Method for cultivating table grapes in high-cold and high-latitude area in winter

Abstract

The invention provides a method for cultivating table grapes in high-cold and high-latitude area in winter. The method comprises the following steps of building a garden, using a high-cold and high-latitude efficient energy-saving solar greenhouse to build the garden, planting and managing grapes, leaving grapes on vines to keep fresh, watering once when the grapes are grown, laying mulch films every other days, controlling the temperature in the greenhouse by controlling time for closing an air inlet, releasing a curtain and rolling up the curtain. When the external temperature decreases below 5 DEG C, thermal insulation is carried out to control the indoor temperature at 10 DEG C. When the external temperature decreases below -10 DEG C, the indoor temperature is controlled at 8 DEG C in day time and at 2 DEG C at night until the grapes are harvested to be sold. The grapes cultivated in the method can be harvested to be directly supplied to fruit markets, the step of storing and refreshing the grapes through chemical agents is removed, the problems of dry peduncles, grape falling, browning, rotting and the like are solved, refreshment of the grapes are achieved to the maximum degree, and meanwhile chemical agent residue is reduced. Furthermore, when the grapes are on grape vines, the sugar content of the grapes gradually increases, and the fruit quality is improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating table grapes in winter in high-cold and high-latitude regions. Background technique [0002] Grape planting in my country has developed rapidly, and it has been cultivated in large quantities from Xinjiang to Gansu, Shanxi, Shandong, Hebei, Dalian in Liaoning, Tonghua in Jilin, and the old course of the Yellow River. Xinjiang is short of water, so the water-saving ability of facility agriculture is even more eye-catching. Xinjiang is a large grape-producing province, and a large number of facility fresh grapes are transported to various regions of the country every year. It takes up to three months from October to New Year's Day and Spring Festival. Table grapes are cultivated in the open field in Changji and other places, but they are not cultivated in the alpine and high latitude areas of northern Xinjiang. In winter, fresh table ...

AI Technical Summary

Problems solved by technology

In winter, fresh table grapes are usually kept fresh after harvesting by picking ripe grapes in batches, pre-cooling, sealing and palletizing at low temperature, and the chemicals used in the process are kept fresh, and drug residues are likely to exceed the standard, or even seriously exceed the standard. Contaminate the grapes and make them inedible

In the storage process, there will be problems such as dry stems, threshing, browning, and rot, which will seriously affect the quality and commerciality of grapes. The annual loss of grapes in my country due to imperfect fresh-keeping technology accounts for more than 20% of the total grape production, causing a large number of grapes. economic loss
