Cultivation method of nandina domestica 1, soil:
Mild acid soil is suitable for Nandina domestica, which can be prepared according to the ratio of sandy soil 5 parts, humus soil 4 parts and manure 1 part. Before planting Nandina domestica, the drainage holes at the bottom of the basin should be covered with broken tiles, and it is better to add a layer of charcoal, which is beneficial to drainage and sterilization.
2. Lighting:
Nandina domestica has a strong adaptability to light. When it is kept indoors, it should be placed in a place with bright light, such as a living room, bedroom, study and other places with good lighting. After the nandina domestica is maintained indoors for a period of time (about one month), it should be moved to a shady place outside (with heat preservation conditions in winter) for a period of time (about one month), and it should be exchanged alternately.
3. Temperature:
Nandina domestica is best maintained in a semi-shady, cool and humid place. Under strong light irradiation, the stems are thick and short and turn dark red, and young leaves? Burn? , leaves turn red; In very shady places, the stems are thin and the leaves are long, and the plants are loose, which is detrimental to the ornamental value and is not conducive to fruiting. The suitable growth temperature of nandina domestica is about 20℃, the suitable flowering and fruiting temperature is 24 ~ 25℃, and it is generally not lower than 0℃ when it is moved into greenhouse in winter. Moved out of the house after Tomb-Sweeping Day the following year.
4. Humidity:
Nandina domestica likes humid or semi-dry climate, and the relative temperature of air in the growing environment is required to be 50 ~ 70%. When the relative humidity of air is too low, the lower leaves will yellow and fall off, and the upper leaves will be dull. As nandina domestica is native to subtropical areas, it has strict requirements on the temperature in winter, and stops growing when the ambient temperature is below 8℃.
5, watering:
Nandina domestica should be watered dry and wet. Water frequently in dry season to keep the soil moist; Water the leaves once a day in summer, and spray them 2 ~ 3 times to keep the leaves moist, so as to prevent the leaves from scorching and damaging the appearance. Pay special attention to watering when flowering, so as not to make the soil dry, and sprinkle water on the ground to improve the air humidity, so as to improve the pollination rate. In winter, Nandina domestica plants are in semi-dormancy, so don't make the basin soil too wet. The watering time should be in the morning and evening in summer and at noon in winter.
6, fertilization:
During the growth period of Nandina domestica, thin fertilizer should be applied to the fine seedlings for about half a month (organic fertilizer containing more phosphorus should be applied). Adult nandina domestica plants should be applied with dry fertilizer three times a year in May, August and1October, and the third time should be applied when they are moved indoors for wintering. The fertilizer can be fully fermented cake fertilizer and sesame sauce residue. Generally, the amount of fertilizer should be less for the first and second time, and the amount can be increased for the third time. During the growth period, cut off the sprouting branches and dense branches at the roots, cut off the branches with longer fruit ears, and leave 1 or 2 branches with lower ears, so as to ensure the beautiful plant shape and facilitate flowering and fruiting.
7, pruning:
Attention should be paid to the pruning of nandina domestica. During the growth period, the sprouting branches and dense branches at the roots should be cut off, and the branches with longer fruit ears should be cut off, leaving 1 and 2 branches with lower ones, so as to keep the plant beautiful and facilitate flowering and fruiting.
