Organic/inorganic special fertilizer for tea and preparation of fertilizer

Abstract

The invention discloses an organic / inorganic special fertilizer for tea and a preparation method of the fertilizer. The special fertilizer is characterized by being prepared from the following raw materials in parts by weight: 12-14 parts of urea, 16-18 parts of ammonium dihydrogen phosphate, 8-10 parts of monopotassium phosphate, 1-2 parts of sodium selenite, 3-4 parts of potassium sulphate, 2-3 parts of quicklime, 5-7 parts of calcium oxide, 8-10 parts of kaolin, 5-8 parts of bauxite, 1-2 parts of ammonium molybdate, 10-12 parts of oil sediments, 14-16 parts of manioc waste, 4-6 parts of humic acid and 15-20 parts of a soil conditioner. The special fertilizer, in comparison with existing organic tea fertilizer formulas at home and abroad, not only contains a great amount of nutrient elements such as N, P and K, but also includes medium and micro elements in a certain proportion; meanwhile, the fertilizer formula disclosed by the invention, combining fertilizer requirement law of tea and soil nutrient situation of tea forest, has stronger specificity. The fertilizer is more well-directed to tea, more complete, balanced and reasonable in nutrition, and better in practical application effect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and relates to a special fertilizer for organic and inorganic tea leaves and a preparation method thereof. Background technique [0002] There are many types of fertilizers currently used for tea planting, among which the special fertilizer for tea mostly adopts nitrogen, phosphorus and potassium compound fertilizers available in the market, which are mainly composed of three inorganic elements N, P, and K, which can meet the growth needs of tea trees in a short time . However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of tea trees and reducing the quality of tea. [0003] At the same time, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, absorbs slowly from tea plants, and has low fertilizer efficiency. Effective balance of various effective nutrien...
