Grafting variety changing method without influencing yield of grapes in same year

Abstract

The invention discloses a grafting variety changing method without influencing the yield of grapes in the same year, which comprises the following steps: a, cultivating of latent buds: thoroughly watering the whole vineyard with special germination accelerating liquid about 15 days before sprouting in spring, keeping soil in the vineyard moist, and promoting the germination of the latent buds; b, green branch grafting: timely grafting branches after the branches are semi-lignified; c, branch traction: timely performing traction on the grafted branches to ensure that scions grow uprightly; d, timely high cutting; and e, reasonable pruning. According to the method, the yield of grapes in the same year is not affected, new trees can bear fruits in the second year, therefore, seamless joint from old varieties to new varieties in the vineyard is completed, and the grafting survival rate is high.

Description

technical field [0001] The invention relates to a method for planting grapes, in particular to a method for grafting and replanting without affecting the output of grapes in the same year. Background technique [0002] Since 2004, my country's table grape planting area has continued to rank first in the world. In recent years, with the successful application of the cultivation model in southern production areas, my country's grape industry has developed rapidly, and the renewal speed of main varieties in various regions is also accelerating. At present, the techniques for updating varieties of vineyards under simple rain-shelter cultivation in the south are mainly to cut down the original varieties to rebuild the garden or graft and replace them. [0003] To rebuild the garden, it is necessary to dig out the old trees and sterilize the whole garden, and then replant the seedlings of good varieties. The effect is slow and the cost is high. At the same time, it is easy to cau...

[0005] However, the time of grafting of existing green branches has a great influence on the growth and yield of grapes

According to the semi-lignification time of scion, adopt the method of prior art, spring grafting survival rate is not high; Summer grafting is suitable for grafting period shorter, is difficult to grasp in production practical application; And autumn winter grafting survival rate is not high and will affect all year's harvest

In addition, the method of prior art all can influence the output of grape in the year of grafting
