Method for regulating grape maturation period in dry-hot valleys

The invention discloses a method for regulating grape maturation period in dry-hot valleys and belongs to the technical field of plant cultivation. The method comprises the steps of conducting first clipping and germination accelerating in the first ten days of March of each year, after branches are matured and aged, conducting second clipping and germination accelerating in the middle ten days of August of the same year when the first clipping and germination accelerating are conducted, and applying hydrogen cyanamide solutions to 2-3 buds on the upper portion of each clipped branch, wherein the mass fraction of the hydrogen cyanamide solutions is 15%. According to the method, by conducting clipping and germination accelerating for twice, namely in the middle ten days of March and in the middle ten days in August, low temperature freezing disaster is avoided in the flowering phase of the grape growth, the high temperature obstacle is avoided in the mature period, so that grapes can appear on the market during New Year's Day and Spring Festival, the yield is increased by 400-500 kilograms per mu, and the yield is increased by 33-50% per mu.
