Problems solved by technology

At present, the most effective and safe method for cultivating large-scale clustered bamboo seedlings is the method of seedling burial, but the propagation materials for seedling burial are collected from naturally distributed bamboo forests. Due to the wide distribution range, the collection is difficult and costly. Difficult to achieve large-scale production and seedling cultivation
The supply of seedlings for the construction of large-scale bamboo raw material forest bases cannot be met; and the quality of the propagation materials is uneven, the quality of the cultivated seedlings is uneven, and the effect of the cultivated seedlings for afforestation is difficult to guarantee

Embodiment 1

[0020] (1) Site selection: Choose a plot with gentle terrain, small slope, sufficient light, thick soil layer, medium or excellent fertility, good soil permeability and drainage, no pests and diseases, and sufficient water source as the nursery;

[0021] (2) Nurturing seasons: Nurturing and building nurseries are carried out in spring and summer.

[0022] (3) Female parent selection: Select 1.5-2.5 year old buried culm seedlings, requiring good culm shape, no pests and diseases, full hidden buds, and robust growth, as the breeding female parent;

[0023] (4) Cutting of the female parent: separate the female parent from the bamboo bushes and take them out completely to avoid hurting the bamboo stalks and bud eyes, and bring as much soil as possible.

[0024] (5) Land preparation and planting

[0025] Comprehensive and fine soil preparation, deep ploughing of more than 30 cm, group spacing of 2 × 2 meters, digging ponds of 134 to 167 / mu, pond specifications: 40 cm deep × 40 c...

Abstract

The invention relates to a method for cultivating excellent propagating materials for large-sized sympodial bamboos, which includes the steps: firstly, choosing a land; secondly, building a nursery in spring and summer; thirdly, selecting female parents; fourthly, performing cutting to obtain the female parents; fifthly, performing land preparation for planting, turning soil at the depth more than 30cm, digging ponds 134-167 per mu according to 2mX2m, setting the specification of the ponds to be 35-40cm in depth, 40-50cm in width and 40-50cm in length, planting the female parents in the prepared nursery timely, and irrigating rooting water; sixthly, performing tending management including irrigation, moisture preservation, fertilizing, soil loosening, weeding and disease and pest damage control; seventhly, topping new plants which substantially grow in fixed shapes at the height 2-4m, or not performing topping; and eighthly, collecting propagating materials and cutting off shoots. By the method, the quality of the propagating materials is guaranteed, transport cost of the materials is reduced, and cultivation cost of bamboo seedlings is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of forestry cultivation, in particular to a method for cultivating excellent propagation materials in a large-scale clustered bamboo collection garden. Background technique [0002] Large-scale clumping bamboo has the characteristics of wide use, high yield and good ecological benefits, and is a kind of bamboo species with great development and utilization value. Bamboo is a long-period one-time flowering plant, blooming only once every few decades, and most bamboo species are highly sterile, so it is difficult to use conventional sexual reproduction. Seedlings are propagated by vegetative propagation methods such as nodes and main branch cuttings. At present, the most effective and safe method for cultivating large-scale clump bamboo seedlings is the method of burying seedlings. However, the propagation materials of burying seedlings are collected from naturally distributed bamboo forests. Due to the wide ...
