Problems solved by technology

Moreover, there is currently not enough bamboo forest area for collecting bamboo stalks and bamboo stalks, so these methods are not conducive to mass seedling cultivation; tissue culture methods are immature, and are limited by the weak outdoor stress resistance of young seedlings, so they cannot be popularized and applied in production. Therefore, the main branch and secondary branch cutting method are mostly used in the cultivation of clustered bamboo seedlings.

Embodiment 1

[0031]A method for rapid rooting of clump bamboo branches, the method specifically includes the following steps:

[0032](1) Branch selection: On January 1, select the main branch of 2-year-old, disease-free cluster bamboo, the main branch is one-year-old and the first node of the main branch has a diameter of 1.8cm;

[0033](2) Branch collection: cut off the junction between the mother bamboo stalk and the main branch to obtain the main branch. The collected main branch will not crack and the bud will not be damaged. The main branch will be cut off the tip, leaving the main branch. The branches are 2 knots, 50cm long, without leaves. After collection, peel off the branches of the branches and perform shading and moisturizing treatment;

[0034](3) Water temperature control: Soak the branches of the stripped branches with a 50mg / L rooting powder aqueous solution for 2 hours, and then place them in 20℃ constant temperature water. The branches are placed upright, and the branches are 10cm away...

Embodiment 2

[0038](1) Branch selection: On January 15th, select the secondary branches of 3-year-old, disease-free cluster bamboo, the secondary branches are 1-year-old and the diameter of the first node at the base of the secondary branches is 2.5cm;

[0039](2) Branch collection: cut off the junction of the main branch and the secondary branch to obtain the secondary branch, cut off the tip of the secondary branch, and leave the branch with 3 nodes, 55cm in length, no leaves, peel off after collection The branches of the branches should be shaded and moisturized;

[0040](3) Water temperature control: soak the branches and stems of the peeled branches with 100mg / L rooting powder aqueous solution for 3 hours, and then pre-treat them with the rooting powder aqueous solution and place them in 26℃ constant temperature water, and put the branches upright. The branches should be 12cm away from the water surface. , Through the water temperature automatic controller, keep the water body constant;

[0041](4) ...

Embodiment 3

[0044](1) Branch selection: On January 30th, choose the main branch of 2-year-old, disease-free cluster bamboo, the main branch is one-year-old and the first section of the main branch has a diameter of 2.2cm;

[0045](2) Branch collection: cut off the connection between the mother bamboo stalk and the main branch to obtain the main branch. The collected main branch will not crack and the bud will not be damaged. The main branch will be cut off the tip, leaving the branch with the main branch. 2.5 knots, 52cm long, leaving no leaves. After collection, peel off the branches and branches, and perform shading and moisturizing treatment;

[0046](3) Water temperature control: Soak the branches and stems of the stripped branches with 60mg / L rooting powder aqueous solution for 2.5 hours, and then place them in 22℃ constant temperature water. The branches are placed diagonally, and the branches and stems are 11cm away from the water surface. The water temperature is automatically controlled. Kee...

Abstract

The invention belongs to the technical field of vegetative propagation of plants, and relates to a rapid rooting method for clustered bamboo branches and application thereof. According to the method,one-year-old thick and strong main branches or secondary branches of clustered bamboos which are more than two years old and free of plant diseases and insect pests are selected, branch roots are soaked in clear water in winter, and the water body is kept at constant temperature; and the water body is aerated and oxygenated, early rooting and excessive rooting of the branch roots are promoted, then the rooted branches are transplanted, and therefore the propagation rate of the clustered bamboos is increased. The method is simple and easy to operate, it is ensured that the branches do not losswater by soaking the roots in the clear water, early rooting of the branch roots and excessive rooting of the branches are promoted through constant-temperature treatment of the water body, and it isensured that rotting of tender roots is avoided through water aeration and oxygenation, so that the propagation rate of the branches is increased, branch seedlings are cultivated in the same year andcan be used for afforestation in the same year, the method is very suitable for application and popularization in production, and good economic benefits, social benefits and ecological benefits are realized.

Description

Technical field[0001]The invention belongs to the technical field of plant asexual propagation, and specifically relates to a method for rapid rooting of clump bamboo branches and an application thereof.Background technique[0002]After blooming, clump bamboo is not easy to set seeds and cannot reproduce sexually. Asexual reproduction is a common method, among which branch cuttings are the most common breeding method. Other methods of reproduction are more difficult to apply. For example, burying stalks, burying joints, burying stalks, etc. require a large amount of strong bamboo stalks. Collecting bamboo stalks, bamboo stalks for seedlings or afforestation will cause great damage to bamboo forests. Moreover, there is currently not enough bamboo forest area for collecting bamboo stalks and bamboo berries, so these methods are not conducive to a large number of seedlings; the technology of tissue culture methods is not yet mature, and is restricted by weak outdoor stress resistance of ...
