Organic biological slow-control fertilizer for tea tree

Abstract

The invention discloses an organic biological slow-control fertilizer for a tea tree. The organic biological slow-control fertilizer comprises the following materials in parts by weight: 30 to 45 parts of chicken manure, 45 to 50 parts of duck manure, 10 to 12 parts of bean dregs, 2 to 9 parts of bone meal, 3 to 6 parts of nitryl humic acid, 5 to 9 parts of potassium chloride, 0.002 to 0.003 part of azotobacter powder, 0.001 to 0.002 part of phosphorus bacterium powder, 0.001 to 0.002 part of potassium bacterium powder, 3 to 6 parts of powdered rock phosphate, 2 to 6 parts of powdered rock potassium, 15 to 20 parts of cotton straw powder, 10 to 20 parts of pinus koraiensis wood chips, 10 to 14 parts of black walnut wood chips, 11 to 20 parts of lemon wood chips, 5 to 8 parts of oilseed straw powder and 14 to 19 parts of turnip straw powder. The organic biological slow-control fertilizer has the beneficial effects that the growth needs of tea leaves are replenished, the quality of the tea leaves is improved and the soil is greatly improved by the organic fertilizer taken as a main material through the addition of a large number of trace elements; the organic biological slow-control fertilizer is high in activity and utilization rate and environmental friendly and cannot perform secondary pollution.

Description

technical field [0001] The invention relates to an organic biological slow-control fertilizer for tea trees. 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.
