Method for high-density layered fruit bearing for grape cultivation in south

Abstract

The invention discloses a method for high-density layered fruit bearing for grape cultivation in south, which includes shed erecting, planting and field management. Field management includes fertilizer application, water control, trimming, fruit bagging and disease and pest control. Shed design and erection, planting and trimming in field management are changed in the method, rain-shading culture trellis sheds shaped as the Chinese word 'feng'(for being abundant) are used, planting density is high, plant and row spacing is 50-70cmX280-320cm, and 340-380 grape plants per mu are planted. The trimming includes trimming in growth period, shaping or trimming in winter, bearing shoot renewing and trimming in summer. By using the rain-shading culture trellis sheds and a branch top trimming technique used with the sheds, group amount and individual distribution in grape planting are optimized, quantity ratio and spatial distribution of branches, leaves and fruits are optimized, intensive utilization of heat, light, fertilizer and water is achieved, cost reduction, efficiency enhancement, rapid growth and high yield can be achieved, fruits can occur in the very year of field planting, high yield level is achieved in the next year, and yield per unit area is above 2000kg.

Description

technical field [0001] The invention belongs to a method for cultivating grapes, in particular to a method for cultivating southern raisins with high density and layered fruiting. Background technique [0002] The cultivation of grapes in our country was concentrated in the north before, and the south was less planted due to the limitations of its climate and cultivation techniques. In recent years, grapes have also been planted in the south, and some successful experiences have been obtained, such as rain-proof cultivation measures. Based on the differences in regions and climates, the cultivation methods of grapes in the south and the north are quite different. At present, the cultivation methods of southern grapes generally include scaffolding, planting methods, field management, etc. Field management includes fertilization, water management, plastic pruning, fruit bagging, pest control and other processes. [0003] Building scaffolding: Generally, cement columns, iron ...

AI Technical Summary

Problems solved by technology

[0014] This cultivation technology adopts the traditional hedge-type rain-proof cultivation greenhouse. The planting density is generally 111 plants per mu (222 plants are planned to be densely planted). The planting density is low and the yield advantage is insufficient; Not high, not conducive to saving costs and increasing efficiency, fast growth and high yield
