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 Propagation of clustered bamboo main culms in high-altitude layering in spring

[0021] 1) Seedling season: The seedling season is selected from February to April every year;

[0022] 2) Select mother bamboo: choose 1-3 year-old healthy mother bamboo without diseases and insect pests;

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

[0024] 4) Material treatment: For the broken shoots of the main culm that have germinated and branched, keep the middle and lower part of the main stalk, with a height of 2 meters, cut off the bamboo branches 1 cm away from the main stalk, and keep the bamboo pocket; The middle and lower part of the main stalk, the height is 2m;

[0025] 5) High-pressure method: choose a plastic bottomless tube bag suitable for the diameter of the main stalk (thickness 1.5 silk, diameter greater than the diameter of the main stalk 6cm, length 30cm), bagging from the top of the main stalk to the bottom, f...

Embodiment 2

[0030] Example 2 Propagation of clustered bamboos in high altitude layering in summer and autumn

[0031] Basically with embodiment 1, difference is as follows:

[0032] 1) Seedling season: The seedling season is from May to October every year;

[0033] 2) select female bamboo: select the healthy mother bamboo of 2-year-old young bamboos for use in that year, wherein the young bamboos of the current year are selected 2-month-old young bamboos that have been lignified;

[0034] 3) Spraying the leaves and watering the rooting agent in the sleeve, the rooting agent is an aqueous solution containing 0.3wt% potassium dihydrogen phosphate and 0.03wt% naphthaleneacetic acid.

[0035] The bamboo seedlings propagated by the above method take root after 1-2 months of branching and leaf expansion, and the root system is semi-lignified in 1 month after rooting, and can be separated and transplanted in the ground. The rooting rate of different bamboo species can reach more than 80%, and ...

Embodiment 3

[0036] Embodiment 3 Congregation bamboo main branch, secondary branch spring and summer high-altitude layering propagation

[0037] see figure 2 , basically with embodiment 1, difference is as follows:

[0038] 1) Select the strong main branch or secondary branch of mother bamboo to carry out high-altitude layering;

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

[0040] The clump bamboo (bamboo kind is the same as embodiment 1) propagated with the above method, the rooting rate of main branch or secondary branch high-altitude layering all can reach more than 80%, the rooting rate of main branch is slightly higher than the rooting rate of secondary branch, both propagation The survival rate of transplanted seedlings has 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 propagation method of clustered bamboo, in particular to a high-altitude layering propagation method of clustered bamboo. Background technique [0002] Bamboo is widely used, has 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, clustered bamboo generally grows faster and has higher yield, so it is suitable for afforestation. 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 afforest...
