Method of regulating producing period of southern grapes to produce spring fruits

Abstract

A method of regulating producing period of southern grapes to produce spring fruits comprises following steps: step 1: rejuvenating grape trees, promoting branches maturing and flower bud differentiation: after autumn grape fruits are matured, applying 50 to 100 kg composite fertilizer so as to recover the trees, wherein it will take more than 28 days to recover trees so as to promote branches maturing and bud differentiation; step 2: tree trimming: timely trimming the grape trees after recovery, and the specific time is based on the harvest time of autumn fruits; selecting well grown foliage branches and partial bearing branches and trimming and defoliating at stem diameter about 1 cm; step 3: winter bud dormancy breaking and germinating: for the grape branches after trimming in step 2, engraving and coating with 2.5% cyanamide for accelerating germination so that the winter buds germinate after 5 to 7 days, inflorescence is present, spraying two thousandths potassium oxide phosphate and borax at 3-leaf stage for two times for further promoting flower bud differentiation. By means of the method of regulating producing period of southern grapes to produce spring fruits, grapes can be produced at two seasons in one year.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for regulating the production period of grapes in southern China to produce spring fruits. [0003] 【Background technique】 [0004] Grape berries are rich in nutrition and have certain medical value, so they are deeply loved by people, and the annual sales volume is constantly increasing, which has good economic benefits. In recent years, my country's grapes have developed rapidly from the north to the south. Since the introduction and planting of the Kyoho variety in 1984, especially the practice and promotion of the "three avoidance" technology, the south of my country has transformed from a sub-suitable area for traditional grape planting to a special advantage planting area. [0005] At present, the biggest problem facing my country's grape industry is that the variety structure is extremely irrational. 80% of the world's grapes are used...

AI Technical Summary

Problems solved by technology

[0005] At present, the biggest problem facing my country's grape industry is that the variety structure is extremely irrational. 80% of the world's grapes are used for winemaking, drying, and juice making, and fresh food only accounts for about 20%. Grapes account for 80% of the total area, about 20% of which are processed. The update speed of good new varieties is slow, and the mix of varieties at different maturity stages is unreasonable. The main varieties planted in the country are still dominated by Kyoho and Red Earth, and the market period of fresh table grapes is too concentrated. , often causing a backlog, leading to price drops and poor economic benefits
