Water-saving irrigation and fruit quality improvement method for grapes

Abstract

The invention discloses a water-saving irrigation and fruit quality improvement method for grapes. The method specifically comprises the step of watering once every 4-8 days from a fruit coloring period to a fruit maturation period, and the watering amount is 2.5-5 L / plant. According to the method, accurate regulation and control can be implemented according to the demand difference of grapes forwater in different periods, water and labor can be saved, the grape fruit quality can be improved, and therefore economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of grape planting, in particular to a method for water-saving irrigation and fruit quality improvement of grapes. Background technique [0002] Drip irrigation technology is to slowly drip water to the soil through drip irrigation belts or drip irrigation pipes, and it is an irrigation system that directly supplies water to the soil. It does not spray or run water in ditches, it just trickles out slowly and penetrates the soil by gravity and capillary action. Drips of water near the roots of the crops keep the soil in the main root zone of the crops constantly optimally hydrated. [0003] Grapes have high requirements on water, and strict control of water in the soil is a prerequisite for growing good grapes. Grapes need more water in the early growth stage or vegetative growth period, and in the late growth or fruiting period, the roots are weaker and require less water. In grape production, irrigation i...

Problems solved by technology

The frequency and amount of drip irrigation are judged by the experience of the grower, and the accuracy of irrigation cannot be guaranteed. Excessive irrigation times or irrigation volume will not only cause waste of agricultural water, but also cause excessive growth of grape branches, falling flowers and fruits during the flowering period, cracking and rotting fruits during the ripening period, and pests and diseases. The occurrence is serious, and a large amount of growth regulators and pesticides have to be used for prevention and control in production, which brings great hidden dangers to fruit safety.

When the irrigation is insufficient, the grapes grow slowly, the internodes become shorter, the leaves are small, and the photosynthesis is weakened, resulting in weak tree growth, which ultimately affects fruit quality and economic benefits
