Facility grape early-maturing promoting culture method

Abstract

The embodiment of the invention provides a facility grape early-maturing promoting culture method, and relates to the field of agricultural planting. Time to market of facility grapes can be 10 to 20 days earlier than time to market of conventional early-maturing promoting culture grapes, and economic benefits are increased. The method includes the steps that during the secondary expansion period of the facility grapes, 2 to 3 bud eyes are reserved on a mother branch in advance, and the mother branch serves as a main fruiting branch in a next year; the reserved 2 to 3 bud eyes grow into young sprouts under the normal management condition and reach the degree of lignification before artificial hibernation of the facility grapes, flower bud differentiation is ahead of time, and the facility grapes bloom and bear fruits in advance.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for promoting early cultivation of protected grapes. Background technique [0002] Grapes, Vitis, deciduous vines. Originated in western Asia, most of the world's vineyards are distributed between 20-52 degrees north latitude and 30-45 degrees south latitude, most of which are in the northern hemisphere. Chinese grapes are mostly grown between 30-43 degrees north latitude. There are many kinds of grapes, there are more than 8,000 kinds in the world, and there are more than 500 kinds in China. Red grape, also known as red earth, is a Eurasian species. Originating in California, USA, it is a grape variety bred by researchers from California State University in the 1970s through hybridization experiments. Since the introduction of this variety in my country in 1987, except for Heilongjiang and Jilin, other provinces in the north have introduced and cultivated it, es...

Problems solved by technology

However, under the condition of extensive management, the reserved 2 twigs may not meet the lignification requirements and affect the differentiation of flower buds, which will lead to less or no fruit in the next year, reducing yield and affecting economic benefits.
