Embodiment 1

[0042] Select a certain number of bamboo clumps, and dig up the topsoil of the bamboo clumps at the beginning of March every year to expose the shoots and bamboo pockets, and use the sunlight to stimulate the germination of the shoots. After drying, apply 4 kg of ternary compound fertilizer with N:P:K ratio of 1:1:1 in the rhizosphere of each bamboo clump; intertillage and weeding from June to July. After the new bamboo stalks are put into the forest, the top shoots should be cut off at the height of 1.5m-2m of the new bamboo stalks to facilitate the sprouting of new bamboos; water and fertilizer management should be strengthened. Remove the old, weak and thin branches in the bamboo bushes without damaging the mother bamboo. Ventilate and ventilate bamboo clumps according to conventional methods to prevent pests from occurring; if pests are found, spray a mixture of carbendazim and trichlorfon at a volume ratio of 1:1 with a volume concentration of 50%, and spray for 10 days ...

Embodiment 2

[0047] Select a certain number of bamboo clumps, and in mid-April every year, dig up the topsoil of the bamboo clumps to expose the shoots and bamboo pockets, and use sunlight to stimulate the germination of the shoots. After drying, apply 4 kg of ternary compound fertilizer with N:P:K ratio of 1:1:1 in the rhizosphere of each bamboo clump; intertillage and weeding from June to July. After the new bamboo stalks are put into the forest, the top shoots should be cut off at the height of 1.5m-2m of the new bamboo stalks, so as to facilitate the sprouting of new bamboo shoots; water and fertilizer management should be strengthened. Remove the old, weak and thin branches in the bamboo bushes without damaging the mother bamboo. Carry out ventilated management on the bamboo grove according to the conventional method to prevent the occurrence of diseases and insect pests; if the occurrence of diseases and insect pests is found, spray the mixed solution with a volume concentration of 5...

Abstract

The invention discloses a dendrocalamus latiflorus section-reserving water-storage cuttage propagation method. The dendrocalamus latiflorus section-reserving water-storage cuttage propagation method comprises the procedures of bamboo grove management, scion acquisition, scion treatment, seed bed preparation, cuttage and post cuttage management, through mother bamboo management and protection, secondary branches which are 1-2 years old, grow robustly and have plump kryptoblasts are collected as scions, and the scions are cut in a seed bed after the scion treatment, so that dendrocalamus latiflorus cuttage tree saplings are obtained after the post cuttage management. According to the dendrocalamus latiflorus joint-reserving water-storage cuttage propagation method, the branches of bamboo plants of 1-2 years old are subjected to scion collection, the collected scions are short and are semi-lignified branches, are vigorous in growth and good in rejuvenation effect, and are the easiest to survive; three sections are reserved for the collected scions, and cuttage propagation material loss can be effectively lowered. The dendrocalamus latiflorus section-reserving water-storage cuttage propagation method is low in cost, easy to operate, fast in expanding propagation, high in propagation coefficient and large in obtained nursery stock quantity, and has good economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for cuttage propagation of hemp bamboo with water storage. Background technique [0002] Mazhu ( Dendrocalamus latiflous Munro), also known as "Sweet Bamboo" and "Daye Wuzhu". This bamboo species has wide adaptability, easy cultivation, fast growth and early maturity, and has good functions of revetment, embankment, wind protection and soil protection, greening and beautification. Bamboo shoots are delicious, sweet and nutritious. Planting hemp bamboo requires less investment, quick results, high income, and remarkable economic, ecological and social benefits. In recent years, it has been widely introduced and cultivated in rural areas. In recent years, southern Guangxi has been widely introduced and cultivated, and mother bamboo transplanting is a conventional afforestation method. [0003] At present, the seedling supply of hemp ba...
