Organic biological controlled-release fertilizer for tea trees

Abstract

The invention discloses an organic biological controlled-release fertilizer for tea trees. The organic biological controlled-release fertilizer is characterized by containing the following substances in parts by weight: 30-45 parts of chicken manure, 25-30 parts of mica powder, 15-20 parts of ammonium nitrate, 9-14 parts of kaolin, 20-25 parts of rice hull ash, 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 part of bacillus thuringiensis powder, 25-30 parts of soybean straw powder, 11-20 parts of lemon wood sawdust, 5-8 parts of oilseed straw powder and 14-19 parts of veronica linariifolia straw powder. The organic biological controlled-release fertilizer has the beneficial effects that the fertilizer gives priority to organic fertilizers, and a great deal of microelements are added, so that the growth needs of tea are supplemented, the quality of the tea is improved, and the soil is also improved greatly; moreover, the organic biological controlled-release fertilizer is high in activity and high in utilization ratio, is free from secondary pollution and is environmental-friendly.

Description

technical field [0001] The invention relates to a tea tree organic biological controlled release fertilizer. 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 fertilizer, the yield of...

Problems solved by technology

These fertilizers are generally expensive, and rarely have porosity and adsorption capacity, and do not have the characteristics of increasing soil fertility and improving soil structure.
