Banded cymbidium needs more fertilizer than other orchids, so it can be diluted every 7 ~ 10 days/time in the vigorous growth period. The best fertilizer is that the ratio of nitrogen, phosphorus and potassium is 10: 10: 5. Because the roots of Vanilla are aerial roots, all well-drained media can be used, such as snake sawdust, broken bricks, charcoal, coarse gravel sand and so on. Whether used alone or mixed, it is a good potted soil. In addition to media, pots and pans for planting Vanilla should also be very particular. Among pots and pans made of various materials, wooden strips and pottery pots are the best, and there are more holes in the pots, which is more conducive to good drainage and air circulation. In addition to wooden strips and clay pots, Vanilla can also grow well on snake boards or tree trunks. Don't change the pots frequently unless there are pests and diseases, and only change the pots 1 time for at least 3 years.
In spring, Bandailan is about to enter the vigorous growth period, which is a good time to change pots. The roots of Eupatorium odoratum, which has been growing for many years, will stick tightly to the inner wall of the flowerpot. Therefore, if it is planted in a pottery jar, it is best to break the jar and change it to avoid damaging the roots when taking out the plants.
Finally, no matter which cultivation method is adopted, remember that the basin soil must be well drained and ventilated.
The propagation of Vanilla can be tissue culture or high bud propagation, but the former is not suitable for families because it requires more professional skills. At the end of autumn, Vanilla will grow tall buds in the axils of leaves. When the tall buds grow to 5 ~ 7.5 cm, cut them off from the mother plant with a sharp sterilized knife, plant them in a pot filled with snake sawdust, and transplant them into a larger pot. Remember to apply medicine to the wound to avoid bacterial infection.
In addition, when the plants cultivated for many years grow to more than 1m, the terminal buds with a length of about 30 ~ 46 cm can be cut off, and the two side incisions can be disinfected with medicine, and then planted in pots to keep them moist. Pest control tough leaves are the main reason why Bandai orchid is not easy to suffer from pests and diseases. Except for snails and slugs, common pests rarely appear on the strong plants of Vanilla. However, when water stays in the leaves for too long, or is infected by viruses, some dark stripes or patches often appear and gradually rot. If the situation is mild, the affected area can be removed. In case the rot range is too wide, the whole orchid must be discarded to avoid infecting other orchids.
Breeding method of eight thousand generations
Key points of 8 thousand generation breeding
The propagation of eight thousand generations is relatively easy, and cutting and leaf cutting are easy to become alive during the growing season. If you have experienced 8000 generations of logging, you should pay attention to the following points:
temperature
The suitable temperature for the growth of eight thousand generations is 15-25℃, and the temperature in winter is above 3℃. The temperature is too high in summer, so pay attention to ventilation.
illuminate
Eight thousand generations are light-loving plants, so family planting should give enough sunshine and put it in a well-ventilated place. When the temperature is suitable, it is best to breed outdoors.
land
Generally, sandy soil with good drainage and air permeability is selected, and excess water can be removed in time when watering. In spring, the basin is changed once every two years, and at this time, the roots can be pruned to remove the necrotic old roots.
liquid manure
During the growth period, the water should be thoroughly dried, 10 once a day, and fertilized once a month, and a thin layer of fertilizer should be sprinkled.
decrease
Prune frequently at ordinary times, and cut off the withered old leaves in time to avoid breeding bacteria. If the plant grows excessively or grows too high, the top branches and leaves can be trimmed for shaping, and the cut parts can be cut off to form new plants.
Cultivation method of jadeite orchid
At present, there are several opinions about Cuilan on the Internet, some say it belongs to cornflower, some say it belongs to Dracaena, and some say it belongs to bluegrass. If there is no emerald in the picture in this article, please choose the wrong one. Cuilan likes the substrate with rich loose vegetables and good air permeability, and can also be fully mixed with vermiculite, perlite and peat soil. This matrix is breathable, clean, sterile and tasteless.
Cuilan likes warm, humid and sunny environment, and is also resistant to shade. However, if it is kept indoors for a long time in a too cool environment, it will also cause the leaves to fade. Therefore, it is best to put the flowerpot on the windowsill in the southeast, so as to fully receive the sunlight.
If the emerald green orchid is kept on the balcony, when the sun is too strong in summer, the flowerpot should be moved indoors, especially at noon, and it should be properly shaded, with a general illumination of 40-50% to avoid the sun burning the leaves.
Cuilan likes warmth and is intolerant of cold. Its optimum growth temperature is 20-28 degrees Celsius. If the summer is hot, the temperature exceeds 32 degrees Celsius, or the winter temperature is lower than 15 degrees Celsius, it will be dormant or semi-dormant.
After the end of 10 in the Yangtze River valley and its south, jadeite orchids should be moved indoors one after another to prevent early frost. Throughout the winter, it is best to control the room temperature between 10-20 degrees Celsius, not too low. At the same time, the potted plants should be placed on the south window sill, so that the sun can shine directly on the plants, and the orientation should be rotated regularly to make them receive light evenly.
Cultivation method of potted orchids
It is a widely distributed plant, not only in China, but also in South Asia and Southeast Asia. Its stem is five to thirty centimeters long and has many leaves. Its leaves are generally alternate, slightly fleshy, 23 cm long and 0/.5 to 2.5 cm wide.
I. Maintenance methods
1, temperature: 15-30 degrees, which is beneficial to its growth. However, too hot or too cold should be avoided. Generally speaking, reaching a high temperature above 35 degrees will make its leaves easy to dry. And below five degrees, it is easy to get frostbite.
2. Illumination: Chinese cymbidium is a shade-loving plant, especially afraid of strong direct light. However, it is best not to have no light at all during the growing period. Can be placed in a semi-shady place, shading in summer, as far as possible in the shade. Otherwise, its leaves are easily burnt. However, if you keep it indoors, there will generally be no problem.
3, watering: the basin is wet, afraid of drying. Therefore, in the season of rapid evaporation, in addition to ensuring adequate water supply, water should be sprayed.
4. Fertilization: Generally speaking, all kinds of farmyard manure can be used. It is best to dilute it with water before use. You can apply it once every ten days or so. In addition, we need to pay attention to the comprehensiveness of nutrition.
Second, feeding skills
1. Propagation: You can use the method of dividing plants. Spring and autumn are the best seasons. Generally speaking, more robust plants can only reproduce once every three years. Choose a densely populated place in pseudobulb, and divide it into several parts from here, each part has at least five pseudobulb. After plants are planted in pots, they need to be placed in a cool place. It takes about ten days to half a month to get used to it.
2, pruning: in the growth period, and after the flowering period, it is best to trim. In the growing period, it is mainly to repair some dry and dense branches to prevent them from consuming too much nutrition. After flowering, the main thing is to trim the residual flowers.
Third, the problem diagnosis and treatment
1, disease: there is white silk disease, which is easy to occur in rainy season and will lead to root rot. It can be prevented by lime. And more ventilation and water control are needed.
2, pests: mainly blue lice, they reproduce very quickly in high temperature environment, and the harm is relatively large. It can be controlled by omethoate or brushed off manually.
Four. Other issues
1. Toxicity: nontoxic and harmless.
2. Can I keep it at home? It is ornamental and can be kept at home.
