Embodiment Construction

[0016] The following examples will further illustrate the present invention.

[0017] The chitosan bran is packed into chitosan powder in the form of powder, and the co-solvent and nutritional additive are mixed in proportion to be packaged into a solubilizing additive solution. The content of chitosan and solubilizing additive according to mass ratio is chitosan: solubilizing additive=1:10, solubilizing agent:nutrient additive=1:0.6. Cosolvent selection H 3 PO 4 solution, H 3 PO 4 The concentration of the solution is 3%, and the nutritional additive is selected from humic acid, ZnSQ 4 and KNO 3 Other organic and inorganic minerals, by mass ratio Humic acid: ZnSQ 4 : KNO 3 =1:0.5:2, the humic acid is organic humic acid.

[0018] When in use, it is prepared on site by mixing the chitosan powder and the solution of the solubilizing additive and diluting with water, and the amount of water is 700 times that of the mixture of the chitosan powder and the solution of the sol...

Abstract

This invention discloses a method for preparing organic tealeaf fertilizer from chitosan by compounding. The organic tealeaf fertilizer comprises chitosan and dissolution additives at a weight ratio of 1 :( 10-15). The dissolution additives comprise cosolvent and nutrition additive at a weight ratio of 1 :( 0.5-0.75). The method comprises: packaging chitosan powder, and mixing cosolvent and nutrition additive to obtain additive solution. When used, chitosan powder and additive solution are mixed and diluted with 500-800 times of water. The organic tealeaf fertilizer can improve the productivity and product quality of tealeaves.

Description

technical field [0001] The invention relates to a fertilizer mixture, in particular to a chitosan compounded organic tea flour fertilizer and a preparation method thereof. Background technique [0002] The organic fertilizers used for tea mainly include commercial organic fertilizers and self-made organic fertilizers. According to their own conditions, various regions are developing various types that have a significant effect on the growth of tea trees, especially causing significant changes in new tea leaves, especially the growth of tea terminal buds. There have been some related reports on the application of chitosan in agriculture, but it is mostly used in food crops and seed coating, etc. There are not many studies on direct application of chitosan as foliar fertilizer, especially in tea. [0003] Publication No. CN1092399 provides a special foliar fertilization progerin for tea leaves, which is composed of nitrogen, carbon, potassium, zinc, sulfur and other nutrient e...
