Double cropping rotation delaying and double cropping promoting cultivating method for facility grapes

Abstract

The invention provides a double cropping rotation delaying and double cropping promoting cultivating method for facility grapes. The method comprises the steps of variety selection, planting and pruning, wherein one-year-old grape mother vines are cultured with prepared vines, autumn delaying fruits are obtained through the annual mother vines of the grapes, and next-year promoted fruits are obtained through the one-year-old mother vines of the grapes. According to the method, the problem that most autumn delaying grapes adopt a late grape variety is solved, the problem that double-cropping grapes within one year need to fruit on the same mother vine is solved, the one-year-old mother vines within one year promote fruiting, different vines of the one-year-old mother vines achieving delaying fruiting fruit twice, and the original predatory mode that the same vine of the same age is pinched, and one-year-old buds are forced to germinate and fruit twice in the current year is avoided. According to the method, the delayed fruits of the one-year-old mother vines appear on the market on New Year's Day, the new-year-old mother vines are promoted to fruit before June, fruiting is carried out in low seasons, and the economic benefits are remarkable.

Description

technical field [0001] The invention relates to a cultivation method for delaying and promoting double ripening by inverting two crops of grapes in a facility, and belongs to the technical field of fruit tree cultivation. Background technique [0002] In the prior art, the mid-autumn delayed grape cultivation mode is generally formed by selecting late-maturing grape varieties; double-ripening in a year means that the first crop of grapes grows in the year and at the same time, the second crop of grapes is formed on the vine at the same time to achieve two crops of fruit, and the same vine is topped in the same year. Forcing buds to germinate to bear fruit twice in the same year is a predatory method, and the same vine bears two fruits in the same year, which affects the yield and quality of grapes. [0003] CN105724166A discloses a method for cultivating grapes in a greenhouse with a single mother vine and two crops in successive years, which requires relatively high-cost se...
