Foliar fertilizer capable of improving quality of summer-autumn tea and application of foliar fertilizer

Abstract

The invention provides a foliar fertilizer capable of improving the quality of summer-autumn tea and application of the foliar fertilizer, and belongs to the technical field of agriculture. The foliar fertilizer capable of improving the quality of the summer-autumn tea contains active ingredients including 24-epibrassinolide, glutathione and ascorbic acid. The foliar fertilizer has the advantages of being convenient to use, low in cost and free of toxic and side effects. After the foliar fertilizer is used, the content of tea polyphenol and theanine can be increased, the phenol-ammonia ratio is optimized, and then the quality of the summer-autumn tea is significantly improved; meanwhile, photosynthesis of tea trees can be improved, the tea yield is increased, an obvious effect is achieved, and the foliar fertilizer can be widely applied to tea garden production.

Description

technical field

[0001] The invention belongs to the technical field of agriculture, and in particular relates to a foliar fertilizer for improving the quality of summer and autumn tea and its application. Background technique

[0002] Tea production is divided into three seasons: spring tea, summer tea and autumn tea. Among them, spring tea has the best quality, the highest yield and economic benefits. In summer and autumn, due to the high temperature and strong sunshine intensity, the tenderness of buds and leaves is poor, the content of tea polyphenols and other substances with bitter taste in tea leaves increases, while the content of amino acids decreases significantly, so summer and autumn teas have heavy bitter taste and poor freshness. , The quality is not high, resulting in the extremely low economic benefits of summer and autumn tea, and the enthusiasm of tea farmers for production is not high. According to reports, about 50% of the fresh leaf raw materials of the ...
