Cutting seedling raising method for ancient tea trees

Abstract

The invention relates to the technical field of cutting seedling raising, and discloses a cutting seedling raising method for ancient tea trees. The method comprises steps as follows: step 1, seedling selection; step 2, preparation of a seedling raising bed: a seedling raising substrate is laid in a bed frame of the seedling raising bed, then a drainage pipeline is laid in the seedling raising substrate, after the drainage pipeline is laid, the surface of the seedling raising substrate is flattened, finally, multiple sets of seedling raising grooves are dug in the surface of the seedling raising substrate side by side, the diameter of each seedling raising groove ranges from 2.5 cm to 3.5 cm, each seedling raising groove is 2-3 cm in depth, the distance between every two adjacent seedling raising grooves is 6 cm, the distance between every two adjacent sets of seedling raising grooves is 8 cm, a drainage groove is formed between the seedling raising grooves in each set, and the width of each drainage groove is 4 cm; step 3, early stage of cutting; step 4, middle stage of cutting; step 5, later stage of cutting; step 6, early-stage maintenance; and step 7, later-stage maintenance. The cutting seedling raising method for the ancient tea trees is high in cutting survival rate, large-scale propagation of cutting of the ancient tea trees can be achieved, and large-scale popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation by cuttings, in particular to a method for seedling cultivation by cuttings of ancient tea trees. Background technique [0002] Ancient tea trees refer to wild ancient tea trees and their communities distributed in natural forests, semi-domesticated artificially cultivated wild tea trees and artificially cultivated ancient tea gardens over a century old. Ancient tea trees are trees that have grown for hundreds of years or even thousands of years. Once they die, they cannot be reproduced. The ancient tea tree is the precious wealth left to us by history, and it is a living cultural relic that cannot be regenerated and replaced. To protect an ancient tree is to protect a history of natural and social development, to preserve a precious and ancient historical relic, and to protect a The excellent germplasm gene bank is also to protect a human and natural landscape. To protect ancient te...

Problems solved by technology

[0003] There are still many deficiencies in the existing ancient tea tree seedling breeding technology, which are mainly manifested in the following aspects: 1) the survival rate of cuttings is very low regardless of hard branches or twigs; disease”; 3) The cost of tissue culture is high, the technology is complex and cumbersome, and rapid large-scale breeding cannot be achieved
