Ask in knowing, and I will answer you with knowing.
Aloe vera is a tropical plant, naturally afraid of cold, but it is also an easy-to-live plant. Of course, in order to make aloe grow fast and more, it must be carefully cultivated according to its characteristics.
Soil: Aloe vera likes to grow in loose soil with good drainage and is not easy to harden. In general, soil can be mixed with some water gravel ash, such as rotten leaf grass ash. The soil with poor drainage and air permeability leads to blocked root respiration, rotten root necrosis and poor growth of aloe.
Temperature: Aloe is afraid of cold. Grow in a frost-free environment for a long time and stop growing at about 5℃. At 0℃, the life process is blocked, and below 0℃, it will be frostbitten. The optimum growth temperature is 15-35℃ and humidity is 45-85%.
Water: Like all plants, aloe needs water, but it is most afraid of stagnant water. In rainy and humid seasons or under the condition of poor drainage, leaves are prone to atrophy, branches and leaves and roots rot or even die.
Sunshine: Aloe needs plenty of sunshine to grow. It should be noted that the new aloe does not bask in the sun. It is best to see the sun only in the morning, and after ten and a half months, slowly adapt to the sun and grow sturdily.
Fertilizer: Fertilizer is indispensable for any plant. Aloe needs not only nitrogen, phosphorus and potassium, but also some trace elements. In order to ensure that aloe is a green natural plant, fermented organic fertilizer should be used as much as possible. Cake fertilizer, chicken manure and compost can all be used, and earthworm manure is more suitable for planting aloe.
Propagation method: Aloe generally adopts techniques such as seedling transplanting or cutting for asexual propagation. The asexual propagation speed is fast, and the excellent characteristics of the variety can be stably maintained.
Aloe vera is a tropical plant and is naturally afraid of cold. But it is also a good living plant. Of course, in order to make aloe grow fast and more, it must be carefully cultivated according to the characteristics of aloe.
Aloe vera likes to grow in loose soil with good drainage and is not easy to harden. General soil can be mixed with some crushed stone ash, such as rotten leaf grass ash. Soil with poor drainage and air permeability will cause root respiration to be blocked and root rot and necrosis, but too much sandy soil will often lead to the loss of water and nutrients, which will make aloe grow poorly.
Aloe is afraid of cold. If it is below 0℃, it will be frostbitten. When the growth is stopped at about 5℃, the optimum temperature is 15℃ ~ 35℃ and the humidity is 45% ~ 85%. Using greenhouse for heat preservation cultivation will solve the wintering problem of planting aloe in northern China. Aloe vera, like all plants, needs water, but it is most afraid of water accumulation. In rainy and humid seasons or poor drainage, leaves are prone to atrophy, branches rot or even die. Aloe grows fastest at around 15℃ ~ 35℃, and most parts of China meet this temperature from March to 10. During this period, it is necessary to strengthen management, loosen soil and weed for many times, which can promote soil aeration, accelerate soil nutrient transformation, promote root development, improve disease resistance and achieve rapid and healthy growth.
In hot summer, timely watering is particularly important. Aloe likes light and heat resistance, but it should also prevent drought in the case of high temperature and less precipitation in summer. Proper watering can get higher yield. Water should not be excessive, and it can be watered once every 5 ~ 10 day. During the vigorous growth period, nutrients in the soil are continuously absorbed by plants, and timely topdressing will affect the growth of aloe. Organic fertilizer is generally slow in fertilizer efficiency, and it is too late to fertilize after aloe growth is affected. Fertilization should not be too much at one time. Don't pollute the leaves. If it is contaminated, rinse it with clean water. Aloe can be picked after planting for about three years. Leaves over three years old have high medicinal value. Generally, leaves should be picked from the lower part of the plant, and the mature leaves should be cooled with the heat to avoid damaging the plant and keeping the intermediates intact during the day. Because the moisture in aloe leaves accounts for more than 96%. The sap from damaged leaves is a loss of nutrition. In addition, damaged blades are not easy to store, which will also affect the storage of other blades. To control watering in autumn, you can use the method of spraying water, even if the soil is dry, it doesn't matter, otherwise it will easily rot the roots. In addition to keeping warm in autumn and winter, we should also pay attention to let aloe see more sunshine as much as possible. Indoor potted aloe can be placed in a sheltered and sunny place. If the temperature is low, you can sunbathe after 9 am and before 3 pm, covered with transparent plastic bags.

narcissus
Temperature, light and water supply are the three elements of narcissus hydroponics in winter. Narcissus needs plenty of sunshine to grow; The suitable temperature is 65438 02℃-65438 05℃; Clean water.
Before hydroponics, peel off the dry brown scales on the outer layer of bulbs, remove the root protection mud and brown rotten roots at the base (be careful not to touch the new white roots), wash the surface, stand upright in a shallow basin without drainage holes, and fix them with pebbles around to prevent dumping. Add clean water to 2/3 of the bulb. When you first come to the basin, you should change the cold and dry tap water once a day, 2-3 days before flowering.
Control flowering time. Under the condition of abundant sunshine and clean water supply, it takes about 40 days for daffodils to soak and bloom when the indoor temperature is 12℃- 15℃. Room temperature is about 18℃, which takes about 30 days. At room temperature of 20℃, it only takes 25 days to blossom; Therefore, the soaking date of narcissus balls can be determined as needed, and the fragrant and beautiful narcissus can be enjoyed in time.
Narcissus doesn't need any flower fertilizer, just water. In order to make narcissus grow strong, it should be taken to the balcony to bask in the sun during the day. If you want to postpone the flowering period, you can take the method of lowering the water temperature, or take the method of pouring water in the basin at night and adding fresh water the next morning. In addition, if you can't see the full flower buds before the festival 10, you can heat the flowers with water, and the water temperature should be close to the body temperature.
As long as you master the conditions of narcissus conservation, you can "open as you like"; Otherwise, it will be delayed, or even the long leaves will not bloom.

(1) peeling: peeling off a layer of brown epidermis outside the bulb.
(2) Ball cutting: at the left and right parts of the upper half of the bulb, at 65,438+0/3, cross-cut downwards, then cross-cut upwards to remove 2-3 layers of scales, and at the same time, cut a knife at the middle part of the bulb between the left and right sides of the bud. When operating, you should avoid hurting the buds and carefully remove the old roots and soil at the bottom.
③ Bulb soaking: soak the cut bulb 65438 in clear water for 0 ~ 2 days, and then rinse the glue flowing out of the bulb.
④ Accelerating germination: Soaked bulbs should be exposed to the sun, and it is best to put them in a container and cover them with a layer of chaff. Water the rice chaff once a day to keep the temperature and humidity. At this time, we should pay attention to the cold, the light is too strong, and we can cover it properly. A week later, when the new buds germinate, they can fully irradiate the sun. After about 50 days, when the flower heads appear, you can take out the narcissus balls, wash them and transplant them into the water basin for planting.

Control of Flowering Period of Narcissus
[Author: at your service reposted from: original hits on this site: 174 common sense input: at your service]
The cultivation of daffodils is closely related to the temperature change, and the flowering period needs to be controlled by adjusting the temperature. If you need to bloom during the Spring Festival, you can generally start soaking in water about 26 days before the festival. Treat narcissus head to make it grow normally.
(1) When the temperature is high, daffodils grow fast, and there are signs of early flowering, they should be shaded appropriately to reduce sunlight.
(2) In case of cold wave, it is estimated that it is impossible to blossom as scheduled, so it is necessary to keep warm, increase the light, and take artificial warmth measures when necessary, such as using a temperature regulator or raising flowers with warm water. In rainy days, you can supplement the light with electric lights.
Narcissus warms up and promotes flowering.
[Author: at your service reposted from: original hits on this site: 109 common sense input: at your service]
Narcissus grows slowly at low temperature, so it can be accelerated by increasing the temperature:
(1) Sunshine warming: put it in the outdoor sunshine or in front of the sunny glass window facing south indoors during the day until it blooms.
(2) Light heating: cover the flowerpot with a plastic cover, turn on the electric lamp for irradiation, and stop when the temperature in the cover rises to 23℃.
③ Electric heater heating: Turn on the electric heater or put the hair dryer in a position that won't burn the daffodils, and let the warm wind blow the flowers slowly for a few days until bloom.
④ Warm water heating: put a little warm water into the basin to raise the water temperature to 12 ~ 15℃.
Salt prolongs the flowering period of daffodils.
[Author: at your service reposted from: original hits on this site: 85 common sense input: at your service]
When the daffodils are all in full bloom, putting a little salt in the pot can prolong the flowering period. Don't put salt when daffodils are in bud, otherwise it will inhibit the bud from opening.

Cactus flowers are divided into two types in cultivation: terrestrial cactus and epiphytic cactus. These two kinds of cactus flowers have very different requirements for temperature, light and water in winter. However, the author believes that the management of their wintering should begin in autumn. After the Mid-Autumn Festival, palm plants should receive as much light as possible. After entering the late autumn, we should gradually control the watering until it stops. When necessary, a small amount of potassium chloride solution can be applied to increase the concentration of plant body fluids and enhance the cold resistance. From late autumn to early winter, don't rush to let palm flower enter the room prematurely. Instead, we should try to let plants receive enough sunshine during the day and exercise at low temperature at night. If there is no cold wave, palm flower can go indoors when the minimum temperature drops to 4℃ at night. Don't break in the middle Generally, after this treatment, palm flower's tolerance to low temperature is enhanced, which is beneficial to overwintering.
Terrestrial cactus is native to arid areas, extremely drought-tolerant, and most of them have the habit of dormancy. It is absolutely forbidden to water after winter, and the soil in the basin is kept dry, so that it enters a dormant state. If the temperature is not lower than 2℃-5℃, you can safely overwinter. Because palm plants have the strongest cold tolerance during dormancy. If improper watering in winter breaks their dormancy and restores their physiological activity, the cold tolerance of plants will be reduced and they will be prone to freezing and rot. If the room temperature is too low during the winter, you can cover the plants with plastic to keep warm. Even when necessary, plants can be wrapped in cotton and straw, and flowerpots can be stored in wooden boxes and cabinets. Even if the temperature is below 0℃, it can safely overwinter. Sometimes when there are many flowers planted at home but the space is limited and the conditions are poor, after winter, when the soil in the basin is dry, you can take off the plants, wrap the bare roots with cotton stalks and put them in boxes or cabinets, which not only saves space, but also keeps warm. When the temperature rises to 10℃, remove the wrapping material of the plant, put it in a pot again, put it in a dry place indoors to gradually adapt to the sunshine, and spray water at noon to make it gradually resume growth. Although this will have some impact on the growth of plants in the coming year, it is also a good way to spend the winter for families with insufficient space and poor insulation facilities.
Epiphytic cactus is native to tropical rain forest with high air humidity, such as epiphyllum, lotus, crab claw orchid and so on. They also need higher temperature and air humidity in winter, and there is no dormancy period, so it is more difficult to manage winter than terrestrial cacti. We need to create an ideal winter environment for them. The author assembled a 5 cm thick glass box by the south window. The bottom of the box is covered with charcoal ash, and a light bulb of 100w is installed in the box to raise the temperature. The cactus is placed in a box, covered with plastic film, and the flowerpot is buried in charcoal ash. When the weather is fine, lift the film properly for ventilation. If the weather is bad, cover it with plastic film, if necessary, cover it with quilt or straw curtain, and light the bulb to heat it. Even on a clear night, the glass box should be covered with a straw curtain or quilt to keep warm. In this way, the temperature in the box is generally maintained between 65438 02℃ and 65438 03℃. Usually a small amount of water can be used to keep the basin soil in a semi-dry state. Usually, it is necessary to properly sprinkle water on the wall of the glass box to maintain a large air humidity in the glass box. This can meet the water demand of epiphytic cactus, so that the plant can maintain a low growth level, which is conducive to the growth and flowering in the next year. Here, if there is no glass box, using double-layer plastic film to build a heat preservation shed for the same management can also make the epiphytic cactus safely overwinter.
Many people are interested in planting cactus, because its fleshy flowers are peculiar in shape and easy to cultivate, which can purify indoor air. So, how can we raise cactus? The author believes that there are the following aspects:
Temperature cactus likes high temperature and dry environment. In winter, the indoor temperature should be kept above 20℃ during the day and not lower than 10℃ at night. Too low temperature is easy to cause root rot, and too high temperature is easy to cause scale insect damage.
Lighting cactus needs plenty of sunshine, but it can't be exposed to strong light in summer, so it needs proper shelter. Indoor cultivation can use light to make it grow healthily.
Soil cactus is suitable for growing in sandy loam with good drainage. Artificial culture soil is often used for indoor cultivation, usually mixed with peat soil and fine sand. It can also be planted by adding fine sand to crushed pine needles and mixing the prepared culture soil.
Watering cactus needs a dry environment, and it is afraid of water accumulation in the basin. Usually, we should keep the basin soil "dry and wet". It is best to water it with dry water.
When fertilizing cactus to change the soil, a small amount of base fertilizer, such as horseshoe slices, bean cakes or sesame sauce residue, should be applied to the bottom of the basin. During the growth period, the fermented organic fertilizer liquid fertilizer should be watered once every half month (the concentration is 20%), and the fertilizer concentration should not be too high.
Pest control in high temperature and poor ventilation environment, pests and diseases are prone to occur. The disease can be sprayed with carbendazim or thiophanate; Spraying dimethoate can kill pests. No matter what medicine is sprayed, it should be done outdoors.
Cactus can be propagated by grafting, generally by flat grafting, and the rootstock can be made of three-edged arrow or strong palm. The specific method is as follows: first, cut off the top of the rootstock, cross-cut the base of the scion, connect the two, and then tie it with a string. Two weeks later, take off the rope.
The aging of cactus begins at the bottom. When aging yellow appears, I painted Dayun 120 on the sphere several times without adding water with a brush to make the yellow fade and make the cactus rejuvenate. This is my experience. Dayun 120 is a plant growth regulator containing hormones, and high concentration is harmless to bulbs. It has less adverse reactions than other plant growth regulators.
You can buy this medicine at the pesticide store.
Nursing care of cactus
Cactus likes sunshine and is not afraid of dryness. So water 1 time a month in spring and summer and 1 time a month in winter. Pay attention to be watered thoroughly when watering; Changing pots should be done in spring. Don't water the newly changed cactus immediately, wait 1 week before watering it. Cactus should be cultivated in a flat-bottomed clay pot, and the soil in it should be mixed according to the ratio of 1 sand 1 soil 1 bone meal, and thin fertilizer should be applied twice a year/kloc-0, so that you can raise cacti well.
Cactus is a perennial succulent plant, native to Argentina and southern Brazil. Its stems are spherical, solitary or clustered, and the old plants are cylindrical. In summer in bloom, flowers grow on the side of the sphere. Most varieties of flowers are trumpet-shaped, white, fragrant and fleshy. Cactus likes light, but it should avoid long-term direct sunlight and shade in summer, and should not be placed indoors for a long time. Medium fertile sandy loam with good drainage and ventilation is needed. The propagation of cactus is mainly through cutting and grafting. In the growing season, the young bulbs are peeled off from the mother bulbs and planted separately, or the bulbs can be grafted on top of other columnar or rattan cacti to cultivate a new landscape. Potted cactus can be planted with 3 parts humus soil, 3 parts garden soil, 3 parts coarse sand and plant ash 1 part culture soil. It is best to put and change pots in early spring. The size of the basin is best to accommodate spheres with tiny gaps. When placing the basin, the basin bottom should be padded with a layer of broken tiles or gravel about 3 cm thick to facilitate drainage. The suitable planting depth is that the root neck of the ball is flush with the soil surface. The newly planted cactus need not be watered, just spray water 2 to 3 times a day. After half a month, a small amount of water can be watered, and after new roots grow around 1 month, the amount of water can be gradually increased. Pay attention to watering the cactus when cultivating, and keep the soil not too dry. The lower the temperature, the drier the soil should be. With the increase of temperature, the dormancy of plants is gradually released, and the amount of watering is gradually increased. However, in hot summer, water should be properly controlled and potted flowers should be placed in the shade. After the dog days, when the weather turns cold, you can resume normal watering. Apply dilute liquid fertilizer or compound flower fertilizer every half month in the growing season, and stop applying fertilizer in winter and hot summer. In summer, besides shading, we should also pay attention to good ventilation. Insufficient light, excessive shading or excessive fertilizer and water will lead to no flowering in cultivation. In northern China, potted plants can be maintained outdoors in the sunny place after the warm weather in spring, and moved indoors in the sunny place before winter, and the room temperature can be kept above 5℃ for safe wintering.
The cultivation and management of cactus is simple, mainly to master watering. Change pots in early spring every year. When changing pots, cut off some old roots and dry them for 4-5 days before planting. Don't plant it too deep, and the root neck of the sphere should be flat with the soil surface. Don't water the newly planted cactus immediately, just spray water and fog 2-3 times a day. After half a month, you can water a little. After 1 month, when new roots have grown, you can gradually increase the amount of water. Proper watering should be done in winter to keep the soil dry. Rooms with good heating conditions can be watered normally in sunny mornings. Spring begins in Zhixia, and with the temperature rising, the frequency and quantity of watering can be gradually increased. It needs a high-temperature and high-humidity environment, but in the high-temperature rainy season, it should be properly watered and placed in a well-ventilated shade. After the dog days, the weather turned cold and normal watering resumed. Apply 1 time decomposed pancake fertilizer every 18 days or half a month in the growing season, and no fertilization is needed in winter.
After autumn, the temperature continues to drop, especially at night. When there is a cold current, the first frost sometimes appears at night. At this time, the physiological activity of cactus tends to be slow, and the water consumption of the sphere is also obviously reduced, so watering must be controlled. If it is sunny and warm weather, it is usually watered twice a week. In autumn, as the temperature turns cold, water it once a week or two. Water evaporation is slow in rainy days, so it is forbidden to water, otherwise the soil will be too wet and the roots will rot easily. After autumn, cactus can't be fertilized more. Generally, it is advisable to fertilize once a month. Fertilization will be stopped at the Cold Dew Festival. If fertilization is applied at this time, cactus will continue to grow, and the growing part of the ball will become tender, reducing its cold resistance. In late autumn, the temperature difference between day and night is large, and the delicate cactus ball is easy to cause freezing injury.
When the weather turns cold in early winter, the cactus will be moved to a place where the sun is common indoors. If the temperature is lower than 5℃, the smaller sphere can be covered with a can bottle, and the larger one can't be bottled, so the whole basin can be covered with a plastic bag. If there are many cactus balls, nail a wooden box (cardboard box is also acceptable) according to the number of balls, and then cover it with plastic film. Pay attention to the airtight seal of the box. It's better to put a 40-watt light bulb in the box. When the weather forecast temperature reaches zero, turn on the light at night to keep warm, and then use old cloth to make a cotton cover on the outer layer of the ball box to keep the triangle safe and warm for the winter. It is often suggested that sunny, warm and windless weather can be used to bask in the sun, thus forming a warm microclimate in the hood, and the temperature in the hood can generally be kept above 5℃. In cold weather, don't open the plastic film to watch the ball, because the ball and triangle will suddenly be attacked by cold wind, the ball will shrink and the triangle will freeze.
After the cold winter, cactus should pay attention to leaving the house in spring. Bloom is warm in spring, chilly in spring and changeable in climate. Don't rush out of the room too early, and don't water it in early spring, otherwise the hard maintenance in winter will be ruined. Before and after going to Grain Rain, when the temperature is stable, you can move outside for normal maintenance and management.
