Embodiment Construction

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

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

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

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 compound organic tea noodle fertilizer and a preparation method thereof. Background technique [0002] The main organic fertilizers used in tea are commercial organic fertilizers and homemade organic fertilizers. According to their own conditions, various regions are developing various types of tea plants that have a significant effect on the growth of tea trees, especially causing significant changes in new tea leaves, especially the growth of tea top buds. There have been some related reports on the application of chitosan in agriculture, but it is mostly used in food crops and seed coatings. There are not many studies on direct use as foliar fertilizer, especially in tea. [0003] The invention patent application with publication number CN1092399 provides a special foliar fertilizer for tea, which is composed of nitrogen, carbon, potassium, zinc, sulfur and other nutrient elements...
