Abstract

The invention relates to application of chitosan oligosaccharide aqueous solution to improve crop quality and usage of the chitosan oligosaccharide aqueous solution. The application of the chitosan oligosaccharide aqueous solution to improve crop quality is characterized in that the chitosan oligosaccharide aqueous solution contains, in weight percentage, 0.001%-0.01% of chitosan oligosaccharide, polymerization degree of the chitosan oligosaccharide is 2-20, and molecular weight of the chitosan oligosaccharide ranges from 500Da to 10000Da, and crops can be vegetables or fruit trees. The usage of the chitosan oligosaccharide aqueous solution to improve fruit quality includes: spraying the chitosan oligosaccharide aqueous solution to leaves of a vegetable crop with a short growth period about 3-5 months for three times every 7-10 days in the middle and late growth period; and spraying the chitosan oligosaccharide aqueous solution to leaves of a tree crop with a long growth period for three to five times every 10-15 days from a young fruit stage. The chitosan oligosaccharide belongs to natural extract, is harmless to crops and human bodies after application to the crops, is environment-friendly, and is simple in usage and easy in popularization.

Description

technical field

[0001] The invention relates to the field of agriculture, in particular to the application and method of an aqueous solution of chitosan oligosaccharide in improving the internal and external quality of fruits of vegetables, fruit trees and other crops. Background technique

[0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the quality of crops, and green agricultural products are becoming more and more popular and occupy a huge market. In the production process of green agricultural products, the requirements for the use of fertilizers are relatively high, and the quality of green agricultural products must be guaranteed.

[0003] In the current production, due to the adverse effects of climate factors, improper fertilizer and water management, use of hormone treatment or pests and diseases, etc., the fruit quality of crops has declined. For example, the sweetness and quality deterioration o...
