Cultivation method of delaying maturity of wine grapes

Abstract

The invention belongs to the field of grape planting, and particularly relates to a cultivation method of delaying maturity of wine grapes. The cultivation method includes the steps that after wine grapes in autumn of the current year are harvested, fertilizer is applied to wine grape trees to culture the wine grape trees, and a basis is provided for the wine grape trees bearing fruits twice in the second year; in spring of the second year, cluster thinning work is carried out on the wine grape trees in the previous year to manage the wine grape trees before delay fruiting, after new shoots grow out, delay fruit promoting work is carried out through pinching and lateral shoot management; delay fruits are harvested after the midmonth of November of the second year. The concept of the delay fruits of the wine grapes is provided, so that the wine grape mature period avoids the rainy season, disease and insect damage to the wine grapes is reduced, the quality, such as the sugar degree, the sour degree and color, of the wine grapes is greatly promoted, and the delay fruits are used for brewing wine.

Description

technical field [0001] The invention belongs to the field of grape planting, in particular to a cultivation method for delaying the ripening of wine grapes. Background technique [0002] Under the climatic conditions of rainy and hot seasons in our country, most areas have insufficient sunlight in the grape growing season, high rainfall leads to excessive growth of grapes, and affects the quality of grapes, especially for wine grapes. The fruit cannot be effectively protected and is directly exposed to the field environment. Under the environmental conditions of rain and heat in the same season, the grapes are susceptible to diseases. Especially for some mid-to-early maturing varieties, due to insufficient light, small temperature difference and high humidity when the grapes are close to maturity, the grapes are seriously diseased and the fruit quality is poor. [0003] Therefore, be badly in need of can stagger rain and heat in the same season, produce high-quality grape, ...
