Grafting and replanting method for tea tree

Abstract

The invention relates to a grafting and replanting method for a tea tree. The method comprises the following steps: sawing rootstocks; selecting scions, and carrying out combined scion treatment by using gibberellin with a concentration of 50mg/L and kinetin with a concentration of 50mg/L; splitting the rootstocks; peeling the scions; inserting the scions; carrying out bagging; and carrying out shading. With the grafting and replanting method provided by the invention, grafting survival rate reaches at least 90%; underground pest prevention and control effects are good; old tea garden can quickly put into production; after grafting, picking starts in the fifth month and is 10 to 15 days earlier than planting; and the method also has the advantages of low energy consumption, simple operation and easy popularization.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for grafting and replanting tea trees. Background technique [0002] The promotion and application of improved tea tree varieties play a decisive role in the benefits and market competitiveness of enterprises. The planting area of ​​tea in Guangxi is 665,000 mu, of which 280,000 mu are from Yunnan Dayequn, accounting for 42.10%. Yunnan big-leaf tea is a good raw material for making black tea, bulk green tea and Pu-erh tea. However, the market for black tea and bulk green tea is weak, the price is getting lower and lower, and the benefit is not high. These old tea gardens urgently need to be transformed and replaced by grafting. The technical measures will help promote the optimization and adjustment of the tea tree variety structure in Guangxi. [0003] At present, there are two ways for tea production and processing enterprises and tea farmers to renew and repla...
