A kind of cultivation method for growing fruit grains of protected grapes

Abstract

The invention discloses a cultivation method for growing fruit grains of facility grapes. The method controls the growth of new shoots of grapes by changing environmental conditions (mainly supplementing ultraviolet rays), removing the occurrence and growth of new shoots of winter buds, and simple pruning. The traditional artificial main and auxiliary shoots are repeatedly topped to control different growth. This method is simple to operate, saves more than 25% of labor, and improves management efficiency; reduces planting costs, and the new growth rate is reduced by more than 36% compared with the traditional technology; the number of auxiliary shoots occurs Compared with the traditional technology, the incidence of secondary shoots is reduced by more than 58%; the fruit grains are significantly increased, and the single grain weight is increased by more than 35% compared with the traditional method; the soluble solid content of the fruit grains is increased by more than 11%, and the high-quality fruit rate is 92% %above.

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
