Precautions for cultivation of Nandina domestica, Nandina domestica is also a very good ornamental plant, especially the bright fruit is more attractive. Nandina domestica is one of the favorite ornamental tree species for pot lovers, but some novices don't know how to raise it. Now share the precautions of nandina domestica cultivation.

Matters needing attention in cultivating nandina domestica 1

Nandina domestica likes warm and humid environment, which is more resistant to shade, cold and easy to maintain. Farming soil requires fertile sandy loam with good drainage. The requirement for moisture is not strict, and it is resistant to both moisture and drought. If you prefer chemical fertilizers, you can apply more phosphorus and potassium fertilizers. Liquid fertilizer 1 ~ 2 times a month during the growing period. After several years of ornamental potted plants, the branches and leaves are aging and falling off, which can be trimmed. Generally, the main stem can be left about 15 cm. 4. After pruning in autumn, the height can be restored to 1, and the crown is full.

Propagation method of nandina domestica

1. Sowing: Collect seeds in autumn and sow immediately after harvest. On the whole seedbed, furrow was dug, the row spacing was 33 cm, the furrow depth was about 10 cm, and the sowing amount was 90 ~ 120 kg per hectare. After sowing, cover plant ash and fine soil and compact. In the second year, the seedlings grow slowly, so it is necessary to weed frequently, loosen the soil and apply light human and animal manure. In the future, attention should be paid to weeding and topdressing in intertillage every year, and planting can be carried out after 3 years of cultivation.

2. Plant separation: In spring and autumn, dig out the overgrown plants, shake off the soil and cut them from the weak foundation. There are 2 ~ 3 stems in each cluster, so it is necessary to take part of the root system, cut off some large pinnate compound leaves at the same time, plant them in the ground or put them in pots, and cultivate them for one or two years to blossom and bear fruit.

Cultivation method of nandina domestica

1, soil: nandina domestica is suitable for slightly acidic soil, and can be prepared according to the ratio of 5 parts of sandy soil, 4 parts of humus soil and manure 1 part. Before planting Nandina domestica, the drainage hole at the bottom of the basin should be covered with broken tiles, and it is best to add a layer of charcoal, which is beneficial to drainage and sterilization.

2. Temperature: Nandina domestica is kept in a semi-cool, cool and humid place. The suitable growth temperature is about 20 degrees Celsius, the suitable flowering and fruiting temperature is 24 ~ 25 degrees Celsius, and it is generally not lower than 0 degrees Celsius when it is moved into a greenhouse in winter. Moved out of the house after Tomb-Sweeping Day the following year.

3. Moisture: Nandina domestica should be watered when it is dry and wet. In the dry season, water frequently to keep the soil moist. In summer, water the leaves once a day and spray them 2 ~ 3 times to keep them moist and prevent them from burning and damaging their appearance. Pay special attention to watering when flowering, so as not to dry the soil, and sprinkle water on the ground to improve the air humidity, so as to improve the pollination rate. The watering time should be in the morning and evening in summer and at noon in winter.

4. Fertilizer: During the growth period of Nandina domestica, apply thin fertilizer to excellent seedlings every half month. Dry fertilizer should be applied to adult nandina domestica plants three times a year, in May, August and June, 5438+ 10, respectively, and the third time should be applied when moved indoors for wintering. The fertilizer can be fully fermented cake fertilizer and sesame paste residue. The amount of fertilization is general, the second time it is less, and the third time it can be increased a lot.

5. Humidity: Nandina domestica likes humid or semi-dry climate, and the growing environment requires the relative air temperature to be 50 ~ 70%. When the air relative humidity is too low, the lower leaves will turn yellow and fall off, and the upper leaves will be dull. As nandina domestica is native to subtropical areas, it has strict requirements on temperature in winter, and it stops growing when the ambient temperature is lower than 8 degrees Celsius.

6. Lighting: Nandina domestica has strong adaptability to light. When placed indoors for maintenance, it should be placed in a bright place, such as a well-lit living room, bedroom, study and other places. After being cured indoors for a period of time (about one month), Nandina domestica should be moved to an outdoor shady place (with heat preservation conditions in winter) for a period of time (about one month), alternately.

Matters needing attention in cultivation of Nandina domestica

1. Change the pot once a year in early spring. When changing pots, some old soil and roots should be removed, base fertilizer should be applied and new culture soil should be filled. 5 parts of sandy soil, 4 parts of humus soil and 1 part of decomposed cake fertilizer powder should be mixed at seedling stage, and 2 parts of decomposed cake fertilizer powder can be added at adult stage.

2. Cultivation of Nandina domestica in well-ventilated flower shade in summer. When watering every day, spray water 1 ~ 2 times on the leaves and nearby ground to improve the air humidity and reduce the temperature.

Nandina domestica likes humidity but is afraid of water accumulation. During the growth and development, the watering frequency should increase or decrease with the weather, and it should not be too much at a time. Generally, water once a day in spring and autumn and twice a day in summer to keep the soil moist. When flowering, the watering time and water quantity should be kept stable, so as to prevent more and less, dry and wet alternately, otherwise it will easily lead to falling flowers and fruits, and the plants are in a semi-dormant state in winter, so watering should be controlled. Too much watering will lead to white growth, hinder dormancy and affect flowering and fruiting in the coming year.

4. Nandina domestica likes fertilizer. From May to September, pancake fertilizer water can be applied once every 15 ~ 20 days, and 0.2% ferrous sulfate water can be poured once every two months. Apply liquid fertilizer lightly at seedling stage, but not intensively (the ratio of liquid fertilizer to water is 1: 10), and apply it slightly intensively at growing stage (the ratio of liquid fertilizer to water is 1: 8). Dry fertilizer is applied once a month in rainy season, and each pot is about 20 ~ 40 grams.

5. The potted plants of Nandina domestica were moved indoors in the middle of June in 5438+ 10, and placed in the direct sunlight in the morning and evening to avoid freezing at room temperature. Spray branches and leaves with warm water once a week to keep them fresh.

6. Nandina domestica should be trimmed and reshaped by changing pots, and the dead branches and weak branches should be thinned from the base to promote the germination of new branches. Generally, it is advisable to leave 4 ~ 5 branches.

Bambusa australis, also known as Tianzhu, Zhu Lan and Lantian bamboos, is an evergreen shrub. Its branches and leaves are slender, leaves turn red in autumn and winter, and red fruits are numerous, which is very lovely. South of the Yellow River can be planted in courtyards, parks and flower beds; Potted plants are often used to decorate windowsills, halls and meeting places in the north of the Yellow River. In winter, you can put fruit ears in bottles to watch. In addition, its roots, stems, leaves and fruits are all medicinal. Breeding is mainly based on sowing and rameting.

When the fruit is ripe in autumn, it should be sown with the harvest, germinated before Qingming in the following year, and properly shaded in summer. Plant division can be carried out in February-March or autumn, and the root of the plant after division is dipped in mud and planted in middle school. It is also propagated by cutting. Annual branches, about 10 cm long, were taken in March and used at the base. Soak in 0. 1% indolebutyric acid solution for 15 seconds, and then insert into the sand bed to a depth of 1/3 of the total length of the cuttings. After inserting, spray water frequently and keep moist.

Pay attention to watering in the early drought season to keep the soil moist, but don't water too much in flowering period to avoid falling flowers. Potters change pots every 3~5 years, combine with ramets and cut off dense branches.

Nandianzhu likes a warm, humid and well-ventilated semi-cloudy environment. Suitable for fertile and loose soil.

To raise nandina domestica well, we should pay attention to the following points:

(1) Change pots in early spring every year. When changing pots, some old soil and roots should be removed, base fertilizer should be applied and new cultivation should be irrigated.

(2) In summer, put it in the shade of a well-ventilated flower bed, and spray 1~2 times a day on the leaves and nearby ground to improve the air humidity and reduce the temperature.

(3) Nandina domestica likes humidity and is afraid of water accumulation. During the growing period, the watering times should increase or decrease with the weather. Generally, water once a day in spring and autumn and twice a day in summer to keep the soil moist. When flowering, the watering time and amount of water should be kept stable to prevent more and less, and dry and wet alternately. Plants are semi-dormant in winter, so water should be controlled. Nandianzhu likes fertilizer. From May to September, pancake fertilizer water is applied every 15~20 days, and 0.2% ferrous sulfate water is poured every two months.

(4) June 10. Move it indoors in the middle, and put it in direct sunlight after entering the room, so that it will not freeze at room temperature.

Nandina domestica likes semi-shady environment, grows poorly under strong light, leaves are not straight, and it is difficult to bear fruit, so it is not suitable for cultivation in direct sunlight.
