Single node and side shoot cutting seedling raising method adopting plug tray and applied to tea trees

Abstract

A single node and side shoot cutting seedling raising method adopting a plug tray and applied to tea trees comprises the following steps: greenhouse preparation, substrate preparation, loading of the substrate to the plug tray, cutting selection, shoot cutting, processing of cutting shoots with rooting powder, cutting and seedling management. Moisture of the substrate and moisture of the cutting shoots are kept in an intermittent spraying manner, the survival rate of the cutting shoots is increased, and the callus forming time and rooting time are shortened; seedlings develop fast after rooting of the cutting shoots provided with the side shoots, and the seedling raising period is shortened; seedling raising through the light substrate and the plug tray is adopted, the root systems of the tea tree seedlings are in a net shape and cluster with the substrate, so that the seedlings are not prone to damage during pulling up, transportation and transplanting, the transplanting survival rate is increased, and the problems of long seedling raising period of single node cutting in an open field by adopting a double-layer film, difficult moisture management of single node and side shoot cutting and the like are solved.

Description

technical field [0001] The invention relates to a method for growing seedlings by cuttings of tea trees, and more specifically relates to a method for growing seedlings by cutting short spikes and lateral branches of tea trees, which belongs to the technical field of tea tree cultivation. Background technique [0002] Tea tree is a kind of perennial economic crop and the main source of income for farmers in mountainous areas. It has been cultivated for thousands of years in my country. The production of tea trees mainly adopts the asexual propagation method of double-layer film covering and short ear cuttings in the open field. The field is used as a border, arched, covered with plastic film and sunshade nets, and semi-lignified reddish-brown branches or green hard branches are selected for cuttings. With one mature leaf (mother leaf), one strong axillary bud, the ear length is 2.5-3.0cm, commonly known as "one bud, one leaf, one inch long". [0003] However, some new varie...
