Like warm and humid environment, avoid strong light exposure and drying, shade-resistant, easy to grow in fertile and loose, large water absorption, good water retention of slightly acidic loam, rotten leaf soil or peat soil is the best. The suitable temperature for growth is 20-25 ℃, and freezing injury is easy to occur when the temperature is lower than 5 ℃. When the temperature rises above 32 ℃, the growth stops.

Breeding methods of Phyllostachys pubescens

1. Sowing: soak the seeds in 40 ℃ warm water for 10 hours before sowing, and the sowing soil should be disinfected at high temperature. The seeds are larger and can be sowed on demand. After sowing, the room temperature is kept at 20: 25 ℃, the box is covered with plastic film, and the humidity is kept above 80%. Generally, it germinates at 20-25 days after sowing. If the room temperature is too low in the process of sowing, not only the emergence of seedlings will be affected, but even the seeds will rot like water stains.

2. Cutting: the cutting effect of tortoise back bamboo is the best from April to May in spring and from September to October in autumn. The cuttings select the lateral branches of the same year with full stem tissue and strong growth, and the cuttings are 20-25 cm long. Cut off the basal leaves, retain the upper leaflets, cut off the long aerial roots and retain the short aerial roots to absorb water and help to root. The mixed substrate of coarse sand and peat or rotten leaf soil was used to keep 2527 ℃ and high air humidity after insertion, and it began to take root about one month after insertion.

3. Ramet: the split of the tortoise-backed bamboo is carried out in summer and autumn, the side branches of the large-scale tortoise-backed bamboo are split off, with part of the aerial roots, and directly planted in the barrel or bowl, not only the survival rate is high, but also the molding effect is fast.

How to raise potted turtles with bamboo?

1, lighting: tortoise back bamboo sex like warm and humid environment, avoid drought, afraid of direct sunlight, otherwise it is easy to cause withered leaves. In summer, the tortoise-backed bamboo should be placed indoors or under the shade shed, not on the balcony where the sun is too strong, so it is easy to die. When the temperature drops to 6 ℃ in winter, the tortoise-backed bamboo should be moved indoors to keep warm.

2. Watering: the water of the tortoise back bamboo should be sufficient, and the culture soil must always be kept moist. During the growth period in summer, the leaves should be watered once in the morning and in the evening, and the leaves should be sprinkled frequently to keep the leaves bright and the air moist. If the water evaporates slowly in winter, it will be irrigated once every 3-4 days. It can be watered once a day.

3. Fertilization: tortoise back bamboo is a more fertilizer-loving plant, so we should pay attention to fertilizing it properly. During the growth period, the tortoise back bamboo will apply thin pancake fertilizer and water every half a month. If the fertilizer is adequate and appropriate, the tortoise back bamboo will grow with pleasant leaf color.

4. Diseases and pests: tortoise-backed bamboo is very vulnerable to shell insects, and its stems and leaves are most vulnerable to shell insects. It can be sprayed with 1000 times of omethoate after cleaning with an old toothbrush. The common diseases of tortoise back bamboo are leaf spot, gray spot and stem blight, so we should pay attention to timely control.

5. Change the basin: the pot of the tortoise back bamboo needs to be changed once a year, and the best time to change the basin is between March and April. When changing the basin, remove the old soil, cut off the withered roots of the tortoise back bamboo, and then add mature organic fertilizer or phosphorus and potash fertilizer as base fertilizer.

Matters needing attention of tortoise carrying bamboo

1, afraid of strong light exposure: back bamboo is a typical shade-tolerant plant, large-scale production must be equipped with shading facilities, can use 50% shading net, especially sowing seedlings and fresh cuttings into live seedlings, avoid direct sunlight, so as to avoid leaf burns. The molded plants should also pay attention to shading in the middle of summer, otherwise the leaves will age and lack of natural luster, which will affect the ornamental value.

2. Fear of air dryness: tortoise back bamboo grows naturally in the tropical rain forest and likes to be moist, but the potting soil will also rot the roots, make the plant stop growing, the leaves droop, lose luster, and the leaves are uneven. Watering should grasp the principle of rather wet than dry, often keep the basin soil wet, but not stagnant water, watering every 2-3 days in spring and autumn. In the midsummer season, in addition to watering every day, water should be sprayed many times to keep the leaves fresh, and hanging cultivation should be sprayed more frequently. In winter, the evaporation of leaves is weakened, and the amount of watering water is reduced.

3. Apply thin fertilizer frequently: Phyllostachys pubescens is a more fertilizer-tolerant foliage plant. In order to have more new leaves and green leaves with natural luster, fertilizer is applied once a month during the growing period. Be careful not to let the fertilizer liquid stain the leaves when applying fertilizer. At the same time, the root of tortoise back bamboo is relatively tender, do not apply raw fertilizer and thick fertilizer, so as not to burn roots. It is best to use "Huiyou" 20Mel 8Mel 20 with high potassium nitrate fertilizer and 20Mel 20Mel 20 general fertilizer in four seasons, which is more beneficial to the growth of tortoise back bamboo.

4. Need to be ligated and reshaped: Phyllostachys pubescens is a large foliage plant with large stems and thick leaves, especially when the ramet of adult plants, it is necessary to set up a frame and tie it to avoid lodging metamorphosis. The bracket is removed after it is finalized. At the same time, when the leaves of the stem nodes grow too dense and the branches grow too long, pay attention to the pruning of the whole plant and strive for natural beauty.
