Double-cropping greenhouse cultivation method for xiangfei grapes

Abstract

The invention discloses a double-cropping greenhouse cultivation method for xiangfei grapes, which is used for cultivating xiangfei grapes in a double-cropping manner by adopting an independent main horizontal vine shaping way in the greenhouse. The double-cropping greenhouse cultivation method for xiangfei grapes specifically comprises the following steps of (1), cultivating first-season grapes, wherein winter pruning is carried out within 20-30 days after harvesting the fruits in the previous year, one fruited cane is selected and remained every 15cm-25cm, and the short cranes with two to three buds are pruned; lime nitrogen is used for accelerating germination after the pruning, the young sprouts are tied vertical to the main vane, the six to eight leaves of the young sprouts are remained and pinched according to the inflorescence before flowering; theone to two leaves of the side sprouts are remained and pinched, one to twoclusters are remained for each sprout, and the clusters are mature in the last ten-day period of June to the first ten-day period of July; and(2), cultivating second-season grapes, wherein summer pruning is carried out at the end of July or at the beginning of August, middle sprouts with four to seven buds are remained for the young sprouts and pinched; the lime nitrogen is used for accelerating germination after the pruning; six clusters are remained per square meter; and the second-season grapes are mature and harvested in the last ten-day period of December. The grapes produced by the double-cropping greenhouse cultivation method for xiangfei grapes are excellent in quality, obvious in anti-season effect, high in sale price, considerable in economic benefits and capable of achieving dependable crop every year.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for cultivating Xiangfei grapes twice a year in a greenhouse. Background technique [0002] The time to market has a great influence on the price of grape sales, and grapes produced out of season have good economic benefits. In the existing two-season grape planting technology, Zhang Xinhua et al. realized the open-field cultivation of Frey seedless grapes twice a year. The first-season fruit matures in early July, and the second-season fruit matures in late October; Liu Jinbiao et al. Make the first fruit of Kyoho grape mature in July, and the second fruit in November; Fan Lihua et al. made the first fruit of Kyoho grape mature in mid-July, and the second fruit in mid-to-late November. [0003] There are two problems in the above-mentioned existing two-season grape planting methods: 1) The ripening time interval between the two seasons of grapes is short, and...

AI Technical Summary

Problems solved by technology

[0003] There are two problems in the above-mentioned existing two-season grape planting methods: 1) The ripening time interval between the two seasons of grapes is short, and there is not enough time to accumulate nutrients, which will affect the quality and yield of the second season grapes, and even affect the quality of the next year. The quality and yield of grapes cannot be stabilized every year; 2) There are more grapes on the market in July, October and November, and it is impossible to obtain good off-season economic benefits
