Method for preparing organic fertilizers for planting high-quality organic tea leaves

Abstract

The invention discloses a method for preparing organic fertilizers for planting high-quality organic tea leaves. The organic fertilizers comprise, by weight, 15-20 parts of broad bean straw powder, 5-10 parts of conch shell powder, 5-9 parts of mastra veneriformis shell powder, 9-14 parts of calcium hydrogen phosphate, 2-5 parts of calcium phosphate, 1-3 parts of traditional Chinese medicine residues, 1-3 parts of distillers' grains, 3-5 parts of potassium nitrate, 2-6 parts of ammonium nitrate, 1-2 parts of calcium nitrate, 10-15 parts of rapeseed meal, 15-20 parts of soybean meal, 68 parts of grass carbon, 25-35 parts of chicken manure, 15-30 parts of other soybean meal, 1-2 parts of bacillus subtilis and 3-6 parts of phosphate rock powder. The method has the advantages that the organic fertilizers contain different types of nutrition such as organic fertilizers and inorganic fertilizers, are non-toxic and are free of side effect or residues or insecticide resistance or environmental pollution; the organic fertilizers are favorable for growth of the tea leaves, nutritional components required by the tea leaves can be obviously supplemented, accordingly, the quality of the tea leaves can be improved, the contents of substances, which are beneficial to human bodies, in the tea leaves can be increased, and soil can be improved.

Description

technical field [0001] The invention relates to a method for preparing an organic fertilizer for planting high-quality organic 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 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. 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 o...

Problems solved by technology

However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, which will affect the growth of tea trees and reduce the quality of tea.

At the same time, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, tea trees absorb slowly, and fertilizer efficiency is low. Effective balance of various effective nutrients cannot be achieved. Due to the unscientific formula of tea fertilizer, the yield of tea is not high. The content of ingredients and trace elements is not high
