The pruning method of tortoise back bamboo

Tortoise back bamboo, also known as Penglai banana, iron magnolia, perforated happy forest taro, tortoise back banana, etc., originated in the Mexican rainforest, sexual preference for warm, humid environment, avoid direct sunlight, not cold-resistant, the north of our country are indoor potted plants, is a very welcome foliage plant, the leaf shape is unique and beautiful, suitable for home beautification decoration home environment, let's take a look at the turtle back bamboo pruning method!

The pruning method of tortoise back bamboo

Tortoise back bamboo stem node leaf growth is too dense, branches grow too fast, pay attention to pruning the whole plant, strive for natural beauty, 2-3 cm away from the base with a sharp blade can be cut off, do not use scissors, the cut will make the wound squeezed water immersion, not easy to heal the wound. Usually, tortoise back bamboo is not suitable for pruning, because there is only one growing point, unless there is a stem waiting for the main stem to grow to about three centimeters thick, and there is a bud bag on the stem, so it is possible to prune it, even if there are new branches, but the original one is gone. if you want to become a big basin, there is only one way to grow three or four trees in a basin.

Breeding methods of Phyllostachys pubescens

The main results are as follows: 1. Ramet propagation: in summer and autumn, the side branches of large tortoise-backed bamboos are split off in whole segments, with partial aerial roots, and directly planted in wooden buckets or bowls. Not only the survival rate is high, but also the shaping effect is fast. It is now the most commonly used in the breeding of tortoise-backed bamboos, and it is also one of the simplest methods.

2. Cutting propagation: stem-node cutting can be used in spring and autumn, and the cutting effect is the best in April-May in spring and September-October in autumn. Cuttings are suitable for stem node incision healing and rooting during this period of time, and survive quickly. Cuttings select lateral branches with abundant stem tissue and strong growth. The cuttings are 20-25 cm long and the leaves at the base are cut off. Retain the upper leaflet, cut off the long aerial root, retain the short aerial root, in order to absorb water, conducive to hairy roots. The mixed substrate of coarse sand and peat or rotten leaf soil was used to keep 25-27 ℃ and high air humidity after insertion, and it began to take root about 1 month after insertion. After the cuttings took root, the axillary buds on the stem nodes also began to sprout and spread leaves. In order to accelerate seedling growth, keep more than 10 ℃ at room temperature, strengthen fertilizer and water management, and seedling shaping can be used as a commodity in the second year after planting.

3. Sowing and propagation: seed sowing is also a more common propagation method for tortoise back bamboo, but the former two are less used. In order to improve the seed setting rate, artificial pollination is needed in order to improve the seed setting rate. 9-10:00 and 3-4 pm secondary pollination is the best, and the pollination success rate is high. It takes 15 months from pollination to seed maturity. attention should be paid to ventilation and fertilizer and water management in the stage of seed development to promote fruiting and fullness. Soak the seeds in 40 ℃ warm water for 10 hours before sowing, and the sowing soil should be sterilized at high temperature. Tortoise back bamboo seeds are larger, can be sowed on demand, keep 20-25 ℃ at room temperature after sowing, cover the box mouth with plastic film, maintain more than 80% humidity, and generally germinate 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.

The culture method of tortoise back 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, the water should be watered once a day in 4 days and once a day every 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 of the tortoise back bamboo, thin pancake fertilizer and water should be applied every half a month. If the fertilizer is adequate and appropriate, the tortoise back bamboo will grow with lovely leaves.

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 turtle back bamboo pot 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.
