Preparation method of organic fertilizer for planting high quality tea

Abstract

The invention discloses a preparation method of an organic fertilizer for planting high quality tea. The organic fertilizer comprises the following substances by weight: 15-20 parts of broad bean straw powder, 5-10 parts of conch shell powder, 5-9 parts of Mactra veneriformis shell powder, 9-14 parts of calcium hydrogen phosphate, 3-6 parts of calcium phosphate, 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 peat, 25-35 parts of chicken manure, 15-30 parts of soybean meal, 1-2 parts of Bacillus subtilis, and 3-6 parts of ground phosphate rock. The fertilizer provided by the invention is rich in organic fertilizer, inorganic fertilizer and other nutrients, has the characteristics of no toxicity, no side effect, no residue, no drug resistance and no pollution to the environment, is conducive to tea growth, can obviously supplement the nutritional ingredient needed by tea, improves the quality of tea, increases the content of substances beneficial to human body in tea, and can improve soil.

Description

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

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
