Affect normal flowering and fruiting. Don't get wet in the rain during flowering and don't water it too often in autumn. In addition, it is necessary to spray and wash the leaves with warm water once a week to prevent the leaves from being polluted by smoke and dust, so that the stems and leaves remain light green all the year round. It is early every day in summer, which can promote its growth and make its leaves bright and green. During the flowering period from June to July, 0.2% dihydrogen phosphate solution was applied every 15 days. The PH value of soil is 6-6.5, which is beneficial to give full play to the availability of nutrients and is suitable for flowering, fruiting, moist and semi-shady plants. Otherwise, it is easy to cause dry tips and scorched edges of leaves, which will affect the ornamental effect. 5% ammonium sulfate should be used for potted evergreen plants, and sandy loam rich in humus should be used for culture soil. Pot soil can be watered with appropriate amount of water at ordinary times. It is better to dry the basin soil than to water it. In addition to keeping the soil moist in summer, we should spray water on the ground around the flowerpot at night to create a humid microclimate. Also pay attention to prevent heavy rain, and add a small amount of 0 when topdressing. Evergreen is the root system of meat, so it should be placed in a dry, ventilated and rainy place, in spring. It grows vigorously in summer and needs to be placed in a cool place to avoid strong light. Change the basin once a year from March to April or 10- 1 1, and it should not be too wet.
In winter, evergreen should be moved indoors for winter, if the room temperature is too high.
In the growing period, the decomposed liquid fertilizer is applied once every 20 days or so; It grows vigorously in early summer, and liquid fertilizer can be applied once every 10 day, which is easy to cause excessive growth of leaves and promote flower bud differentiation, so as to facilitate better flowering and fruiting. Therefore, in winter, we should keep the air moist and the basin soil slightly wet. Generally, it is advisable to water 1-2 times a week. The aged rhizomes and persistent dead leaves must be removed and planted with fertilized acid cultivation soil. Leave it in the shade for a few days after serving.
The key points of evergreen cultivation are: keeping warm. It is easy to cause root rot when changing pots. In winter, if the leaves of evergreen are yellow and scorched, or even the whole plant withers, it is mainly because the roots can't absorb water, which affects the growth. If it is placed in a sunny and well-ventilated place, the temperature is kept at 6- 18 degrees, which consumes a lot of nutrients, so the growth will be weak in the second year, and it is most afraid of water accumulation and waterlogging. Therefore, it is impossible to water more.
2. How can I grow evergreen?
Evergreen is a perennial evergreen perennial plant of Liliaceae, native to China and Japan.
Also known as Yongdong, Open Throat Sword, Ebony Poison, Iron Rod and White Grass. Its leaves are clustered on the rhizome, bright and thick, lanceolate, undulate all over the body, sharp at the end, and 15-50 cm long.
Flowering from April to June, the scape is extracted from the leaves, and the height is about 10 cm. The spike is the terminal, and the colors are white and green. After flowering, the spherical berries turned from turquoise to bright red in September-10, and did not bear fruit until March-April of the following year, which was very beautiful and attractive.

Evergreen likes warm, humid and semi-cloudy; I like slightly acidic sandy loam containing humus; Relatively cold-resistant; Avoid water and sunlight to prevent the leaves from turning yellow.
Old leaves should also be pruned once a year in April and August to promote growth. If it wants to bear more fruits, it should ask snails to help pollinate at night during flowering.
Because its flowers bloom at night and the opening time is short, snails are used to night activities and like to eat their pollen, so they kill two birds with one stone. It can also be artificially pollinated.
The propagation of Evergreen is mainly divided into plants, which are carried out in March-April or 9-65438+1October. It can also be sown and propagated in March-April, then emerge and bloom in 3-4 years, which is rarely used in China.

3. How should evergreen be propagated and cultivated?
The breeding method is: sowing in greenhouse, sowing in each hole 1 grain, covering soil thickness 1. 5cm, keep moist, 30? After 40 days, the seedlings can come out together, so we should immediately put a bamboo curtain on the glass roof of the greenhouse to shade the sun.
The next spring, the seedlings were planted in small flowerpots, and after two years of cultivation, they could form furnishings. Propagation by ramets: Perennial plants can grow many young plants from underground rhizomes, and can be ramed by turning over pots and changing soil, and each ramet should have a sound root system.
First, plant the surface sand in the "two-barrel" pots, and after the roots grow full, use the culture soil instead of the larger flowerpot to continue the culture. In the urban gardens in the south, it can be planted in a single row in the open space under the flower border or shade, with a spacing of 60? 100cm, hole depth 15? 20cm, apply a small amount of organic fertilizer and irrigate after planting.
As indoor ornamental plants, they can be planted in the shade of indoor gardens sporadically, but potted plants are the main ones. Gaza can be used to cultivate rotten-leaf soil, which cannot contain alkali, and the soil should be turned over every two years.
Every spring and autumn 10? Apply liquid fertilizer every 15 days, and don't let the sun shine; In summer, ventilation should be strengthened to prevent heatstroke and cooling; In winter, you can move into the cold room for the winter, or you can continue to display it.

Guangdong evergreen, also known as bright silk grass.
It is a perennial evergreen herb of Araceae. The leaves are mostly oval or rectangular, dark green and shiny.
(1) likes warm and humid environment, has strong negative resistance, avoids drying and is afraid of direct sunlight. Slightly cold-resistant, the room temperature can be kept above 5℃ in winter to safely overwinter; When the temperature is too low, it is vulnerable to freezing injury.
It needs loose and fertile culture soil. If the basin soil is sticky, it is easy to cause root rot. Potted soil should be mixed with humus soil and garden soil with a small amount of river sand.
(2) Apply 1 every month during the vigorous growth period. When the compound liquid fertilizer containing twice as much nitrogen and potassium is sufficient, the stem is thick and the leaves are thick. Water every day in hot summer 1? Twice, the water should be dry and wet alternately in spring and autumn, and the water should be controlled in winter.
If the pot soil is too wet at this time, the leaves will turn yellow and the roots will rot easily. (3) Guangdong Evergreen can thrive in a place with strong indoor scattered light. If exposed to strong light, the leaves will get sunburned or even die.
Old plants that have grown for several years tend to crawl and have poor posture, so we should pay attention to re-cutting.
