Annual double-cropping cultivation method for greenhouse grapes

Abstract

The invention discloses an annual double-cropping cultivation method for greenhouse grapes. The annual double-cropping cultivation method comprises the following steps of fruiting mother branch winterpruning for germination promotion, summer fruit shoot and flower and fruit management, secondary fruiting mother branch pruning, secondary fruiting mother branch dormancy breaking and winter fruit shoot and flower and fruit management. According to the method, the problems that in sunlight greenhouse early-maturing culture, the grape flower bud formation quality is poor, insertion joint positionsare high, continuous year high yields are influenced, and fruiting positions move outwards are solved; and the problems that the grape delayed cultivation cost is high, the mature period is not easyto control, and premature senility of leaves is caused are solved. Secondary fruits are produced through the empty production period after grape early-maturing culture and fruit picking, great waste of facility resources, manpower and material resources is reduced, the market period of grape fresh fruit picking is greatly expanded, the economic benefits of grape growers are greatly increased, andthe ecological benefits, social benefits and economic benefits are quite remarkable.

Description

technical field [0001] The present invention relates to the field of fruit tree cultivation, and in particular relates to a method for cultivating grapes in a greenhouse twice a year. Background technique [0002] In recent years, due to the continuous and rapid growth of grape planting scale and fruit production across the country, coupled with the relative concentration of ripening and listing periods, the table grape market has been slow to sell in the peak season of grape production, and the supply exceeds demand in the off-season. The contradiction between supply and demand is very prominent, and grape growers increase production without increasing income Not uncommon. In recent years, through the promotion of early cultivation of grapes in solar greenhouses, although the contradiction between supply and demand of fresh grapes in spring has been alleviated, and the economic income of growers has increased, the market for grape picking and fresh fruit during the New Year...

AI Technical Summary

Problems solved by technology

[0005] Generally speaking, the early cultivation technology and delayed cultivation technology of greenhouse grapes both advance or delay the time to market of fresh grape products, and have not realized the annual two-crop production of greenhouse grapes, which is not prominent in terms of economic benefits

In addition, in some areas, the emergence of early cultivation has greatly changed the current situation of the agricultural industry. People have adopted it one after another, and it has become the first choice to improve planting efficiency. The market advantage is gradually lost, and the income is greatly reduced

[0006] From a technical point of view, the early cultivation of grapes in solar greenhouses has poor flower bud formation quality and high insertion nodes, which affects the high yield in successive years and the problem of moving fruit parts outward; the delayed cultivation of grapes is costly, the maturity period is difficult to control, and the premature senescence of leaves is serious.
