The latest culture method of tortoise back bamboo

Tortoise back bamboo is an evergreen vine, native to the Mexican tropical rain forest, tortoise back bamboo plant shape is beautiful, the leaf shape is strange, the leaf color is dark green, and full of luster, the ornamental effect of the whole plant is good. In addition, it also has a peculiar ability to attract carbon dioxide at night, sweet breeding in the room has a certain role in purifying indoor air, is now widely used as a family potted plant culture.

The growing environment of tortoise back bamboo

1. Like warmth and avoid severe cold: tortoise back bamboo is native to the Mexican rainforest. It likes warm environment and avoids freezing cold weather. The temperature above 5 ℃ will not suffer frost damage, and the temperature above 12 ℃ will grow well.

2. Like shade and cool and avoid strong light: tortoise back bamboo has strong shade tolerance, grows very well in semi-shade environment, shows exuberant growth, well-developed aerial roots, hypertrophic leaves and bright dark green leaves.

3. Like wetting and avoiding waterlogging: tortoise back bamboo likes to grow in a humid ecological environment. There are many Rain Water in the south, if the waterlogging accumulation time is too long, there will be rotten roots, rotten stems and leaves.

4. Bogey lean soil: tortoise back bamboo likes fertile soil, especially fertile sandy loam. Although it can grow on thin red and yellow soil, its growth becomes weaker, tree posture is deformed, leaves become smaller and leaf color becomes lighter, which affects the ornamental effect.

5. Like soil fertilizer and avoid chemical fertilizer: tortoise back bamboo often applies organic fertilizer, such as cake fertilizer, artificial organic fertilizer, livestock and poultry manure, soil fertilizer and so on. Its tree is strong, the leaves are as big as plates, the leaves are thick, and the leaves are dark green and glowing, especially the tortoise shell pattern is more clear.

Breeding methods of Phyllostachys pubescens

The propagation of tortoise back bamboo can be reproduced by sowing, cutting and striping. Now the editor introduces the breeding methods of tortoise back bamboo as follows:

1. Sowing and reproduction

Phyllostachys pubescens blossoms in summer, in order to improve the seed setting rate, artificial pollination is needed, and the second pollination from 9 am to 10:00 and 3 pm to 4 pm is the best, and the success rate of pollination is high. It takes 15 months from pollination to seed maturity. The seeds are oval, yellowish green, like soaked green beans.

Sowing should be carried out indoors, either in the ground or in the pot. Soak the seeds in 40 ℃ warm water for 10 hours before sowing. The sowing soil can be made of plain sand, and the sowing soil should be sterilized at high temperature. Plant row spacing 4~5cm, soil cover thickness 0.2~0.8cm. Spray enough water after sowing, cover the small arch shed, keep the room temperature at 20 ℃ 25 min after sowing, and keep the humidity in the shed above 90%. 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.

When the seedlings were first unearthed, the stems and leaves were not divided, and they were green curved cones. After a week, the cotyledons gradually expanded into heart-shaped, forming young plants with distinct stems and leaves. The seedlings have strong phototaxis and grow faster under suitable conditions of light, temperature and humidity. The sowing seedlings are about lOcm high, and can be put on the pot when 2 true leaves have been born.

2. Cuttage propagation

In fact, cutting propagation is to bury the stem segment, cut off the stem on the mother plant and retain the stem base of the lower 3-4 nodes, so that the hidden buds of their nodes can germinate, and two new stems can be produced soon after cutting and continue to grow. The truncated stem is cut from the Internode according to 2-3 segments, and the following three methods are used for cutting:

① apical leaf burying method: there are no terminal buds and axillary buds on the stem of Phyllostachys pubescens. The primitive body of the new leaf is pregnant in the petiole of the upper stem leaf, which is covered by milky white longitudinal bracts before milking, and the new leaf is born after the bract is split, and the stem extends forward when the new leaf is unfold. at the same time, a groove is left in the lower part of the old leaf, so that the plant continues to grow upward. Therefore, when cutting with the stem segment at the top of the stem, it should be buried with the top leaf, and the bracts on the petiole can split quickly after rooting and give birth to new leaves. The plant can be formed by cutting in the same year. When burying the stem, the stem segment can be planted upright into the cutting medium mixed with plain sand and peat soil, and a bamboo pole can be set up to straighten the terminal leaf.

② with side leaves burying stem method: most of the stem segments intercepted from the upper part of the mother plant stem have leaves, and it is best to keep a leaf when burying the stem, which is quite beneficial to rooting and leaf extraction. Generally retain a leaf at the base, let the stem segment and the soil surface obliquely buried in the cutting substrate, and set up a bamboo pole to straighten the leaves.

③ method of burying stems without leaves: most of the stem segments in the lower part of the stem have no leaves, so they can be concentrated in the most cutting container and buried in the matrix at 15 degrees to the soil surface, so that the crescent leaf marks at the top of the node ring and the soil surface are facing up.

No matter which method is used, the aerial root on the stem should be cut off before burying. Cuttings should be carried out in a well-ventilated room or under a shade in late spring and early summer. Cutting seedlings should always be maintained in a hidden place, often spray water, keep the substrate fully moist, and improve air humidity at the same time. Under the soil temperature of 20 Mel 25 ℃, 35 Murray is expected to take root in 50 days.

3. Striping propagation

During the period from May to August, the aerial roots from the internodes of the stem in the first year were inserted into the water bottle or buried in the basin soil, and many fibrous roots could be produced in about one month. When the root grows to 2cm, cut off the lower stem node of the tortoise back bamboo with a sharp knife, and plant the aerial root part of the cut stem into the pot.

4. Ramet propagation

In summer and autumn, the side branches of large tortoise-backed bamboos are chopped off in whole segments, with partial aerial roots, and directly planted in buckets or bowls, which not only has a high survival rate, but also forms quickly.
