Special environment-friendly tea compound fertilizer and preparation method of special environment-friendly tea compound fertilizer

Abstract

The invention discloses a special environment-friendly tea compound fertilizer and a preparation method of the special environment-friendly tea compound fertilizer. The special environment-friendly tea compound fertilizer is characterized by being prepared from the following raw materials in parts by weight: 5-7 parts of urea, 12-14 parts of ammonium chloride, 4-5 parts of potassium sulphate, 8-10 parts of calcium superphosphate, 12-14 parts of ground tea branch powder, 7-9 parts of crushed crude pearlite powder, 12-15 parts of peat soil, 6-8 parts of crushed bamboo charcoal powder, 1-2 parts of manganese sulfate, 1-2 parts of copper sulfate, 1-2 parts of sodium sulphide, 3-4 parts of aluminum powder, 1-2 parts of amino acid, 1-2 parts of ammonium molybdate, 3-5 parts of soybean meal and 15-20 parts of a soil conditioner. The special environment-friendly tea compound fertilizer is scientific in formula, contains trace elements and natural controlled release materials, is capable of meeting the demand of the growth of tea, is capable of increasing the yield of the tea and improving the quality of the tea, and also capable of conditioning soil and maintaining the soil ecological equilibrium.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special compound fertilizer for green environmental protection tea and a preparation method thereof. Background technique [0002] There are many types of fertilizers currently used for tea planting, among which most of the special fertilizers for tea are nitrogen, phosphorus and potassium compound fertilizers that can be purchased in the market. . 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 leaves. [0003] At the same time, although simple organic fertilizer is rich in organic matter, the release of nutrients is slow, the absorption of tea trees is slow, the fertilizer efficiency is low, and an effective balance cannot be achieved between various effective nutrients. The content of ingredients and trace elements is not ...

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.

[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 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
