Soilless planting method for grapes in northern cold region

Abstract

The invention provides a soilless planting method for grapes in a northern cold region. According to the method, the growing temperature of the grapes is controlled through increase of high-temperature light source irradiation on shaded surfaces of the grapes, so that the grapes can be planted earlier, the fruit swelling period is prolonged, the average size of fruit is increased, and meanwhile, the problem of large difference in taste of the grapes of the same plant due to uneven irradiation on the grapes is solved.

Description

technical field [0001] The invention relates to the field of grape planting, in particular to a soilless grape planting method in the northern cold region. Background technique [0002] Grapes are one of the oldest fruit tree species in the world. Plant fossils of grapes have been found in Tertiary strata, indicating that they were all over Europe, Asia and Greenland at that time. Grapes are native to western Asia and are cultivated all over the world. About 95% of the grapes in the world are concentrated in the northern hemisphere. [0003] The minimum temperature required for grape growth is about 12°C-15°C, the minimum ground temperature is about 10°C-13°C, the optimum temperature for flowering is about 20°C, and the optimum temperature for fruit expansion is 20°C-30°C. If the temperature difference between day and night is large, the coloring and sugar content are better. In some cold areas in the north, due to the large temperature difference between day and night, th...

Problems solved by technology

[0005] In order to solve the problems of the prior art, the present invention provides a soilless planting method for grapes in cold northern regions. The growth temperature of grapes can be controlled by increasing the irradiation of high-temperature light sources on the back of the grapes, which can advance the planting time of grapes and prolong the production of fruit. During the expansion period, the average size of the fruit is increased, and at the same time, the problem of the large difference in the taste of the same grape caused by the uneven illumination of the grapes is solved
