Method for producing special fertilizer for tea trees by using jasmine dried residues and tea dust as raw materials

Abstract

The invention relates to a method for producing a special fertilizer for tea trees by using jasmine dried residues and tea dust as raw materials. The special fertilizer is prepared from the following raw materials in parts by weight: jasmine dried residues 25-30 parts, tea dust 20-25 parts, jasmine stems 20-30 parts, mulberry branches 20-25 parts, peanut vines 10-15 parts, tea tree branches 10-15 parts, roots of kudzu vine rattan 8-10 parts, peanut bran 8-10 parts, black tea fungi culture 3-5 parts, urea 3-5 parts, calcium superphosphate 1-3 parts, potassium oxide 1-3 parts, zymophyte 0.5-1 part and trace elements 0.2-0.5 part. The trace elements comprise the following components in parts by weight: ferrous sulfate 3-5 parts, manganous sulfate 3-5 parts, zinc sulfate 2-3 parts, magnesium sulfate 2-3 parts, copper sulfate 1-2 parts and boric acid 0.5-1 part. The special fertilizer for tea trees is balanced in nutrition, high in utilization rate and good in absorption; and soil cannot be caked easily.

Description

technical field [0001] The invention relates to the technical field of fertilizers for agricultural production, in particular to a method and product for producing special fertilizers for tea trees by using jasmine residue and tea dust as raw materials. Background technique [0002] As a crop with high economic benefits, tea trees are widely planted in southern my country. However, with the widespread planting of tea trees, the demand for fertilizers for tea trees has increasingly become a bottleneck for the growth and cultivation of tea trees; Fertilizers mostly use nitrogen, phosphorus and potassium compound fertilizers available on 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 period of time. Many farmers use these compound fertilizers excessively in order to increase tea production. Fertilizer, such long-term use will destroy the soil aggregate structure, and easily cause soil compacti...

[0002] As a crop with high economic benefits, tea trees are widely planted in southern my country. However, with the widespread planting of tea trees, the demand for fertilizers for tea trees has increasingly become a bottleneck for the growth and cultivation of tea trees. There are many types of fertilizers used for tea tree planting, among which tea Fertilizers mostly use nitrogen, phosphorus and potassium compound fertilizers available on 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 period of time. Many farmers use these compound fertilizers excessively in order to increase tea production. Fertilizer, such long-term use will destroy the soil aggregate structure, easily cause soil compaction, soil hardening and salinity, 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
