Problems solved by technology

At present, the commonly used propagation methods mainly include branching, burying stalks, burying knots, and cuttings of bamboo branches, etc., which have low seedling efficiency and high cost; all the seedlings cultivated are bare-rooted seedlings, and the survival rate of afforestation is low, especially after long-distance transportation. In the case of prolonged drought, the survival rate of afforestation is lower
It often leads to no forest in afforestation, which not only increases the cost of afforestation, but also delays the time for afforestation
[0003] A few places also use the container method to cultivate bamboo container seedlings, but the cost is high and the transportation is inconvenient, resulting in high afforestation costs and slow afforestation speed, which is difficult to meet production needs, which greatly affects the promotion and use

Embodiment 1

[0020] Example 1 The main stalks of clumping bamboo were reproduced in high altitude in spring

[0021] 1) Nursery season: The nursery season is selected from February to April each year;

[0022] 2) Choose mother bamboo: Choose 1-3 years old healthy mother bamboo without pests and diseases;

[0023] 3) Select the material position: choose the middle and lower part of the main stalk;

[0024] 4) Material treatment: Cut off the shoots of the main stalk that has sprouted branches, keep the middle and lower part of the main stalk, 2 meters in height, cut the bamboo branches 1cm away from the main stalk, and keep the bamboo pockets; cut off the shoots of the unsprouted main stalks, keep The middle and lower part of the main stalk, the height is 2m;

[0025] 5) High pressure method: use plastic bottomless tube bags (thickness 1.5 filaments, diameter greater than the diameter of the main stalk 6cm, length 30cm) that are compatible with the diameter of the main stalk, bagging from the top of ...

Embodiment 2

[0030] Example 2 High-altitude layering propagation of clump bamboo in summer and autumn

[0031] It is basically the same as Example 1, with the following differences:

[0032] 1) Nursery season: the nursery season is selected from May to October each year;

[0033] 2) Choose mother bamboo: choose the healthy mother bamboo of 2 years old, and choose the 2 month old young bamboo that has been lignified;

[0034] 3) Leaf spraying and irrigating the rooting agent in the sleeve, the rooting agent is an aqueous solution containing 0.3wt% potassium dihydrogen phosphate and 0.03wt% naphthalene acetic acid.

[0035] The bamboo seedlings propagated by the above method will take roots 1 month to 2 months after the branches and leaves, and the roots can be semi-ligninized 1 month after rooting, and they can be separated and transplanted. The rooting rate of different bamboo species can reach more than 80%, and the survival rate of transplanting can reach more than 90%. Transplanted from August ...

Embodiment 3

[0036] Example 3 The main and secondary branches of clumping bamboo are propagated by high-altitude layering in spring and summer

[0037] See figure 2 , Basically the same as embodiment 1, the difference is as follows:

[0038] 1) Choose the strong main or secondary branches of the mother bamboo for high-altitude layering;

[0039] 2) The rooting agent is an aqueous solution containing 0.1 wt% potassium dihydrogen phosphate and 0.06 wt% naphthalene acetic acid.

[0040] For clumping bamboo (bamboo species are the same as in Example 1), the rooting rate of the main branch or secondary branch can reach 80% or more. The rooting rate of the main branch is slightly higher than that of the secondary branch. The survival rate of seedlings after transplanting reached more than 90%.

Abstract

The invention belongs to the field of plant cultivation and relates to a high-altitude layering propagation method for sympodial bamboo. The method comprises the following steps of: breaking shoots of main culms, main branches and secondary branches, keeping main culms or secondary branches which are 1-3 meters in height on the middle lower part, cutting growing bamboo branches which are 1-2 centimeters away from the main culms, main branches or secondary branches, and keeping bamboo bases; and covering every culm ring of the main culms, main branches or secondary branches with a plastic bottom-free barrel bag, tightening the lower side of each barrel bag, filling a root inducing substrate which comprises a culm bud and a branch bud, tightening the upper side of each barrel bag to form a cylindrical container, and keeping the root inducing substrate in each barrel bag wet. Due to the adoption of the method provided by the invention, the problems of low survival rate of bare-rooted bamboo seedlings, high cost and severely insufficient bamboo seedling supply during the development of the bamboo industry are solved; and moreover, the method is easy to operate, materials are readily available, the cost is low, and large-scale popularization and application to production are facilitated.

Description

Technical field [0001] The invention belongs to the field of plant propagation, and relates to a method for multiplying clump bamboo, in particular to a method for high-altitude layering propagation of clump bamboo. Background technique [0002] Bamboo has a wide range of uses, with important ecological benefits and high economic value. Bamboo industry development is one of the most potential emerging industries in my country's forestry construction. Compared with scattered bamboo, clump bamboo generally grows faster and yields higher, which is suitable for afforestation. At present, the commonly used propagation methods mainly include arborization, burying of stalks, burying knots, bamboo cuttings, etc. The seedling raising efficiency is low, and the cost is high; all the seedlings cultivated are bare-rooted seedlings, and the survival rate of afforestation is low. In the case of prolonged drought, the survival rate of afforestation is lower. This often leads to afforestation...
