Anti-season cultivation method of fresh grapes

Abstract

The invention belongs to the technical field of gardening cultivation, and relates to an anti-season cultivation method of fresh grapes. The anti-season cultivation method comprises the following steps: selecting a medium and early mature fresh grape variety, harvesting primary mature fruits from the middle period of June to the middle period of July, and performing anti-season secondary fruit facility cultivation, wherein the anti-season secondary fruit facility cultivation comprises the following steps: performing summer pruning from the late period of August to the early period of September, pruning middle shoots of winter buds of new shoots fruiting in the current year, remove all leaves, forcing germination of the winter buds, wiping buds and fixing the shoots, and topping; when the lowest temperature is below 10 DEG C after autumn, regulating the temperature in a shed through a double-layer grape shed and automatic temperature control equipment, so that the temperature in the shed at night after autumn is not lower than 10 DEG C; harvesting mature secondary fruits from the late period of December to the late period of January. By the anti-season cultivation method, the problems of the temperature regulation and control and the like during anti-season cultivation are solved, the secondary fruits can begin to mature on New Year's Day and during the Spring Festival, production of anti-season grapes is fully achieved, and the concentrated marketing period of the fresh grapes is avoided so as to achieve better economic benefits.

Description

technical field [0001] The invention relates to an off-season cultivation method for table grapes, which belongs to the technical field of horticultural cultivation. Background technique [0002] Grape is one of the oldest fruit tree species in the world. It is cultivated all over the world. It is rich in nutrients, such as sugar, organic acid, protein and vitamins. At present, the ripening period of grape fresh fruit is mainly from July to October. The market The main supply period of Shanghai grape fresh fruit is from June to November, and the market supply is very small at other times, and most of them are imported or stored grapes, which are relatively simple. In order to adjust the market supply period of grape fresh fruit, meet the market demand, and increase the income of grape planting, relevant personnel have carried out research on the cultivation of grape twice a year, and achieved corresponding results. It is mainly to promote cultivation in spring: use single-l...

[0004] Another method is to use the secondary shoots of summer buds to bear fruit. In this way, two generations live together, which will easily cause insufficient nutrient supply and decline in quality. The supply period is the same as delayed cultivation.

[0005] To sum up, the relatively mature off-season cultivation supply period still has limitations. It can only guarantee that there will be no batches of ripe grapes in January and February before New Year's Day and after mid-March; It is easy to affect the output of the current year and the next year; delaying the tree-hanging period of cultivation is also lossy, and the supply time is limited
