Biological organic fertilizer and preparation method thereof

Abstract

The invention discloses biological organic fertilizer and a preparation method thereof. The biological organic fertilizer is organic food tea plantation special-purpose fertilizer and comprises, by weight, 35-45 parts of urea, 15-20 parts of ammonium dihydrogen phosphate, 16-26 parts of potassium dihydrogen phosphate, 9-14 parts of kaolin, 8-15 parts of bauxite, 3-6 parts of potassium tripolyphosphate, 2-6 parts of sodium metaphosphate, 7-14 parts of disodium hydrogen phosphate, 0.001-0.002 parts of bacillus thuringiensis powder, 25-30 parts of soybean straw powder, 25-30 parts of potato straw powder, 10-15 parts of scapharca subcrenata shell powder, 15-20 parts of Biaoha shell powder, 5-9 parts of China fir wood chip, 5-9 parts of platycladus orientalis wood chip, 0.001-0.002 parts of microzyme powder and 0.001-0.002 parts of actinomyces powder. Compared with the existing organic tea fertilization formula, the biological organic fertilizer contains macroelement nutrients such as N, P and K, contains a certain amount of medium and trace elements, and has good specificity by combination with a tea fertilizer needing rule and tea tree soil nutrient present situation.

Description

technical field [0001] The invention relates to a special fertilizer for planting organic food tea leaves. Background technique [0002] There are many types of fertilizers currently used for tea tree 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 destroy 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. 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 nutrients cannot be achieved. Due to the unscientific formula of tea fertilizer, the yield of ...
