Method for pre-judging rooting ability of tea tree variety

Abstract

The invention discloses a method for pre-judging the rooting ability of a tea tree variety, which comprises the following steps of: culturing collected tea tree ears in an aerosol culture mode, counting the germination rate and the survival rate of the tea ears, combining ear picking season influence factors, and determining the rooting ability of the tea tree variety in three seasons of April to May, June to July and September to October every year. Culturing the tea branches of the tea trees in an aeroponic culture environment to carry out a germination culture test; calculating according to Y = M * X * S according to the statistical average germination rate and survival rate of the tea ears and the ear picking season influence factor, and finally obtaining a tea ear rooting capability coefficient for analysis; when the tea spike rooting ability coefficient (Y) is lower than 50%, the potential rooting ability of the tea tree is weak, and when the tea spike rooting ability coefficient (Y) is 51%-70%, the potential rooting ability of the tea tree is medium; when the rooting ability coefficient (Y) of the tea spike exceeds 71% or above, the potential rooting ability of the tea tree is strong. After the cutting rooting strength of the variety is pre-judged according to the method, in the subsequent large-scale cutting process, corresponding technical pretreatment can be carried out on the tea trees in the early stage according to the biological characteristics of the tea trees, and the rooting ability of the tea trees is improved.

Description

technical field [0001] The invention relates to a tea tree cultivation technology, in particular to a method for pre-judging the rooting ability of a tea tree variety. Background technique [0002] Tea tree is an important economic crop in mountainous areas in my country, and cultivating high-quality tea seedlings plays an important role in promoting the development of the tea industry. At present, cutting propagation is the main way of propagation of cloned tea plant varieties, and it is also one of the key steps in the selection and breeding of cloned tea plant varieties. However, some of the selected rare and excellent varieties and endangered tea tree resources have problems such as breeding and promotion difficulties. For example, the collection of germplasm resources of the Tea Institute of Lishui Academy of Agriculture and Forestry Research for many years, the selection and breeding of some tea tree lines with excellent characters, the resources are rare and cuttings ...

AI Technical Summary

Problems solved by technology

However, some selected rare and fine varieties and endangered tea tree resources have problems such as breeding and popularization difficulties. For example, the Tea Institute of Lishui City Academy of Agriculture and Forestry Sciences has collected germplasm resources for many years and bred some tea tree lines with excellent traits. The resources are rare and cutting Due to the low rooting rate and other problems, it is difficult to promote it in a large area in suitable planting areas. Therefore, it is necessary to judge the rooting ability of the tea tree variety at an early stage, and then carry out corresponding technical treatments on the tea tree to improve the cutting rooting rate of the tea tree, which can be greatly improved. It is especially necessary to select high-quality, rare and difficult-to-reproduce tea tree varieties to save female parent resources and seedling breeding cycle, etc.
