The latest Culture method of Phyllostachys pubescens

Phyllostachys pubescens is a common woody flower species in southern China, also known as red quat, candle, red wolfberry, diamond yellow, Phyllostachys pubescens, orchid bamboo and so on. It is an evergreen shrub of Berberaceae. Because of its beautiful plants, bright fruits and strong adaptability to the environment, it often appears in garden applications. Let's take a look at the breeding methods of Phyllostachys pubescens.

Growth habits of Phyllostachys pubescens

Nantian bamboo likes a warm and humid environment, which is more shade-resistant, cold-resistant and easy to maintain. Cultivated soil requires sandy loam with fertile and good drainage. The requirement of moisture is not very strict, which can withstand both moisture and drought. Prefer fertilizer, but apply more phosphorus and potash fertilizer. Liquid fertilizer was applied once or twice a month during the growing period. Potted plants after a few years of viewing, branches and leaves aging and falling off, can be pruned, generally the main stem can be left about 15 cm, April pruning and autumn can be restored to a mystery height, and the crown is plump.

Propagation methods of Phyllostachys pubescens

1. Sowing: seeds are collected in autumn and sown immediately after harvest. On the whole seedbed, trench was opened according to the row spacing of 33 cm, the depth was about 10 cm, and the seed was sown evenly. The sowing rate was 90,120kg per hectare. After sowing, cover the plant ash and fine soil and press it tightly. The seedlings grow slowly in the second year, so weeding, loosening the soil and applying light human and animal manure should be done frequently. In the future, attention should be paid to weeding and topdressing every year, which can be planted in the nursery after 3 years.

2. Ramet: dig out the clump-shaped plants in spring and autumn, shake off the soil, cut off from the weak combination of roots, 2 or 3 stems per clump, take part of the root system, cut off some large pinnately compound leaves, plant or pot them on the ground, and blossom and bear fruit after a year or two of culture.

Culture methods of Phyllostachys pubescens

1. Soil: Phyllostachys pubescens is suitable for slightly acidic soil, which can be prepared according to the proportion of 5 parts of sandy soil, 4 parts of rotten leaf soil and 1 part of manure soil. Before planting Phyllostachys pubescens, cover the drainage holes at the bottom of the basin with broken tiles, adding charcoal is better, which is conducive to drainage and sterilization.

2. Temperature: Phyllostachys pubescens is best maintained in semi-shade, cool and humid places, the suitable growth temperature is about 20 ℃, the suitable flowering and fruiting temperature is 24-25 ℃, and it is moved into the greenhouse in winter, generally no less than 0 ℃. Ching Ming Festival moved out the following year.

3, moisture: Nantianzhu watering should be dry and wet, watering frequently in dry season, keeping the soil moist, watering once a day in summer, and spraying 2 or 3 times to the leaf surface, keeping the leaf surface moist, preventing the leaf tip from withering and scorching, damaging the appearance. Flowering should pay special attention to watering, do not make the basin soil dry, and sprinkle water on the ground to increase air humidity, in order to improve the rate of pollination. Watering time, summer season should be in the morning and late, winter should be carried out at noon.

4. Fertilizer: during the growing period, the fine seedlings of Phyllostachys pubescens are fertilized once every half a month. The adult Phyllostachys pubescens plants are fertilized three times a year, in May, August and October, respectively, and the third time should be fertilized when moving into the room for overwintering. The fertilizer can be fully fermented cake fertilizer and sesame sauce residue and so on. Generally speaking, the amount of fertilizer application should be less in the first and second times, and the amount can be increased in the third time.

5. Humidity: Nantianzhu likes a humid or semi-dry climate environment, which requires that the relative air temperature of the growing environment is 50-70%. When the air relative humidity is too low, the lower leaves yellowing and falling off, and the upper leaves are not glossy. Because Phyllostachys pubescens is native to the subtropics, the temperature in winter is very strict, and the growth stops when the ambient temperature is below 8 ℃.

6. Lighting: Nantianzhu has a strong ability to adapt to light. When it is put indoors, it should be placed in places with bright light, such as well-lit living room, bedroom, study and so on. After the bamboo has been maintained indoors for a period of time (about a month), it should be moved to an outdoor place with shade (heat preservation in winter) for a period of time (about a month), so it will be exchanged alternately.

Matters needing attention in Phyllostachys pubescens culture

The main results are as follows: 1. The pot should be changed once a year in early spring. when changing the pot, part of the old soil and old roots should be removed, basic fertilizer should be applied, and new culture soil should be filled in. 5 parts of sandy soil, 4 parts of rotten leaf soil and 1 part of rotten cake fertilizer should be mixed at seedling stage, and 2 parts of mature cake fertilizer can be added at the end of mature stage.

2. Phyllostachys pubescens is cultured in a well-ventilated shade cool place in summer. When watering every day, it is necessary to spray water on the leaf surface and the nearby ground for 1 or 2 times to increase the air humidity and reduce the temperature.

3. Nantianzhu likes to be wet but afraid of stagnant water. During the period of growth and development, the times of watering should increase or decrease with the change of weather, and should not be too much each time. In general, it is watered once a day in spring and autumn and twice a day in summer to keep the basin soil moist. When flowering, the watering time and amount of water should be kept stable to prevent sudden increase and decrease, sudden wet and dry, otherwise it is easy to cause falling flowers and fruits, and plants are in a semi-dormant state in winter, so watering should be controlled. If watering too much, it is easy to grow, hinder dormancy and affect the blossom and fruit in the coming year.

4. Nantianzhu likes fertilizer. From May to September, thin cake fertilizer water can be applied every 15 to 20 days, and 0.2% ferrous sulfate can be poured every two months. The application of liquid fertilizer at seedling stage should be light but not concentrated (1:10 for liquid fertilizer and water) and slightly thicker at adult stage (1:8 for liquid fertilizer and water). Dry fertilizer is applied in the rainy season, once a month, about 20 to 40 grams per pot.

5. The potted bamboos were moved indoors in the first and middle of October, and put them in a place where they can be exposed to direct sunlight sooner or later, so as not to freeze at room temperature. Spray the branches and leaves with warm water once a week to keep the leaves fresh.

6. Phyllostachys pubescens should be pruned in combination with changing pots, and withered branches and weak branches should be removed from the base to promote the germination of new branches. generally, it is appropriate to retain 4 or 5 branches.
