Problems solved by technology

[0002] Sunburn is a plant physiological disease that seriously affects the quality of fruit in the market. In arid and semi-arid fruit production areas, strong solar radiation and high temperature for a long time during the growing season will cause the surface temperature of the fruit to reach a very high level, causing fruit sunburn Diseases, reduce fruit quality, increase agricultural economic losses

Abstract

The invention discloses an agent for preventing and treating sunburn of crops, which comprises sodium humate, polyethylene glycol and sugar maple leaf-papaya extract; 10-20 parts of diol, 60 parts of sugar maple leaf-papaya extract; the sugar maple leaf-papaya extract is a composite extract of sugar maple leaves and papaya pulp. The sunburn control agent for crops in the invention is mainly obtained by extracting natural green plants, is non-toxic and polluting, and is healthy and environmentally friendly; and has a good control effect on apple sunburn, improves fruit quality, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation and planting, in particular to a sunburn prevention and control agent for crops and a preparation method thereof. Background technique [0002] Sunburn is a plant physiological disease that seriously affects the quality of the fruit market. In arid and semi-arid fruit production areas, long-term intense solar radiation and high temperature during the growing season will cause the fruit surface temperature to reach a very high level, causing fruit sunburn. Diseases, reduce fruit quality and increase agricultural economic losses. Increased levels of UV radiation due to the continued depletion of stratospheric ozone, as well as increasing global warming from fossil fuel emissions, point to more frequent extreme weather events in the future. On the other hand, with the increase in consumer demand for high-quality fruit, the competition in the fruit industry has become increasingly fier...
