Abstract

The invention provides preparation and application methods of foliar fertilizer for increasing freshness of tea and relates to the technical field of foliar fertilizer for tea trees. The foliar fertilizer is characterized by being prepared from a main ingredient, a stabilizer, a synergist, a pH adjuster, a preservative and the like, wherein the main ingredient is soybean meal hydrolyzed amino acid powder, and soybean meal hydrolyzed amino acid powder is compound amino acids and rich in various nutrients; the stabilizer provides a stable environment for nutrients of the foliar fertilizer and plays a chelating role; the synergist is used for improving penetration and spreading capacity of the foliar fertilizer to reduce the surface tension; the pH adjuster plays a role in regulating pH of the foliar fertilizer; the preservative is used for preventing the free amino acids from deterioration during long-term storage and plays a role in bacteriostasis and sterilization. The foliar fertilizer has the beneficial effects that the content of the free amino acids in the tea is increased significantly, the quality of the tea is improved well, higher market demands are met, and the market competitiveness of the tea in the province is improved.

Description

Technical field: [0001] The invention relates to the technical field of tea tree foliage fertilizer, in particular to a method for preparing and applying a foliar fertilizer for increasing the freshness of tea leaves. Background technique: [0002] Anhui Province is located in the middle and lower reaches of the Yangtze River. It has a mild and humid climate and four distinct seasons. The area of ​​mountains and hills accounts for more than 60% of the province. Especially the Huangshan Mountain in the south and the Dabie Mountain in the southwest are suitable for tea plantation. They are the main production and processing places for tea in our province. Among the top ten famous teas in the country, Anhui accounted for three, namely Huangshan Maofeng, Lu'an Guapian and Taiping Houkui. It is the only province in the country that has more than two brands. Under the superior conditions of the three, Anhui famous tea has spread far and wide, and has been loved by a large number o...
