Double-cropping cultivation method of grapes

Abstract

The invention discloses a double-cropping cultivation method of grapes. The method comprises routine management in an open field during a culturing and growing period, temperature, humidity, lighting and nutrient and water management in a sunlight greenhouse, growth regulation and control of branches, leaves, flowers, fruits and roots, as well as routine cultivation and management techniques. Premature grape varieties with fast flower bud differentiation, strong repeated fruiting capability, high and stable yield and high disease resistance are selected; trimming, bud promotion, as well as pinching and lateral shoot processing of first-crop fruit and second-crop fruit are performed for matching; lateral shoot processing and spike determination management are performed on the second-crop fruit; and more than two times of fruiting in one year is achieved through a comprehensive management technology of forced pinching and lateral shoot processing. According to the method, grapes are cultivated in semiarid areas in western part of Liaoning province in the north, two times of fruiting in one year are achieved, a use mode for land cultivation of the grapes in the north is changed, and the grape yield is increased by more than two times; the land use capability is doubled, and appreciation of land value is maximized; and product quality, yield, economic benefit and safety of the grapes are better than the grapes cultivated under natural conditions and in a traditional sunlight greenhouse.

Description

technical field [0001] The invention relates to the technical field of grape production and cultivation, in particular to a cultivation method for grapes bearing fruit twice a year. Background technique [0002] The origin of grapes is in western Asia. Most of the vineyards in the world are distributed between 20-52 degrees north latitude and 30-45 degrees south latitude, and most of them are in the northern hemisphere. Most of the grapes in China are grown between 30 and 43 degrees north latitude. In recent years, the grape industry has made great progress in my country, with large cultivation area and high yield. Because grape is the only fruit tree that can bear fruit many times a year in deciduous fruit trees, it has not been rationally utilized in production, and there are no supporting technical measures to promote it both at home and abroad. Rational use of the habit of grapes to bear fruit many times a year can increase the yield per unit area, prolong and adjust t...
