Cultivation method for enlarging fruit grains of facility grapes

Abstract

The invention discloses a cultivation method for enlarging fruit grains of facility grapes. According to the cultivation method, the growth of grape shoots is controlled by changing environmental conditions (mainly for supplementing the ultraviolet rays), removing winter bud shoots and inhibiting the growth of winter bud shoots and simply shaping and trimming the shoots, compared with the traditional way for controlling the growth by manually pinching main and auxiliary shoots for multiple times, the cultivation method of the invention is simple in operation, the labor is saved by more than 25percent, and the management efficiency is improved; the planting cost is reduced, and the growth rate of the shoots is reduced by more than 36 percent compared to the traditional technology; the number of auxiliary shoots is reduced, and the occurrence rate of the auxiliary shoots is reduced by more than 58 percent compared with the traditional technology; the grape grains can be significantly enlarged, and the unit grain weight is increased by more than 35 percent compared with the traditional method; and the grape grain soluble solid content is increased by more than 11 percent, and the rate of high-quality fruits is more than 92 percent.

Description

technical field [0001] The invention relates to a cultivation method for growing fruit grains of protected grapes, and relates to the field of plant cultivation. Background technique [0002] my country's grape cultivation area and output rank first in the world. In recent years, the market's demand for grapes, especially the demand for facility grapes, has increased, and facility grape planting has higher benefits. Grape is a kind of fruit tree that is extremely suitable for cultivation in facilities. In the facility, grapes can be harvested early or delayed according to the change of artificial conditions, and the fresh fruit supply period of grapes can be extended, so as to obtain higher economic benefits. [0003] Due to the weak light intensity in the facility (mainly due to the cultivation time and the shading of the facility), the relative humidity of the air is high (compared with the open field condition), the photosynthetic products of the grape are less, and the ...

Problems solved by technology

[0004] The disadvantage of these measures is that the continuous pinching of new shoots requires a lot of labor, especially under the condition of expensive labor, which greatly increases the planting cost and reduces management efficiency; the rapid growth of new shoots wastes nutrients, which is not conducive to the transportation of nutrients to fruits; The effect is very limited, and 1-2 kinds of growth regulators also have the effect of inhibiting the growth of new shoots and promoting the increase of fruit grains, but the effect is not ideal, and there are certain side effects
