Grape flower bud differentiation regulation planting method

Abstract

The invention discloses a grape flower bud differentiation regulation planting method. The grape flower bud differentiation regulation planting method comprises garden establishment and planting, tree body management, flower bud differentiation process regulation, young fruit exogenous treatment, winter shaping and trimming, fertilizer and water management, and the like. According to the planting method, through utilization of reasonable trimming and core picking strength and combination of spraying of ethephon with proper concentration, the spica forming rate of new shoots can be increased obviously, the differentiation process of the grape flower buds is accelerated, the flower bud differentiation cycle is shortened by 15 to 20 days, and a positive effect on production of the grapes at the second season is achieved; meanwhile, through exogenous calcitonin nutritional treatment of summer young fruit in the expanding period and proper calcitonin concentration and treatment cycle, the cytomembrane structure of fruit peel is protected, the lipid peroxide content of the cytomembrane is reduced, the inhibition on the photosynthesis of grape leaves by high temperature is relieved, the sunburn resistance and softening resistance of the fruit are improved, and the commodity of the fruit is greatly optimized.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a planting method for regulating and controlling grape flower bud differentiation. Background technique [0002] Grapes are not only delicious, but also have high nutritional value. They are known as the top four fruits in the world and one of people's favorite fruits. In recent years, with the improvement of people's living standards, people's demand for grapes is also increasing day by day. According to statistics, my country's grape industry is developing rapidly. By 2014, the country's grape cultivation area has reached 760,000 hectares, with a total output of 12 million tons, and it is still rising. The area and output of my country's fresh grapes have ranked first in the world. Grape planting in my country has also developed from traditional advantageous production areas to all provinces and regions across the country, especially the grape planting area in southern produc...

Problems solved by technology

Due to the unstable flower bud differentiation of some grape varieties, the flower bud differentiation process and time of different varieties and different nodes are different, which makes it difficult to determine the follow-up management time of planting operations, which increases the difficulty of regular grape planting

At the same time, the fruit development period of conventionally planted grapes coincides with the high temperature and high humidity season, which is prone to fruit softening, sunburn and other physiological diseases, greatly reducing fruit quality
