Sustained/controlled-release fertilizer for tea trees

Abstract

The invention discloses a sustained / controlled-release fertilizer for tea trees. The sustained / controlled-release fertilizer is characterized by containing the following substances in parts by weight: 30-45 parts of chicken manure, 15-20 parts of ammonium nitrate, 9-12 parts of potassium sulfate, 0.1-0.2 part of lactobacillus powder, 0.1-0.2 part of nitrobacterium powder, 0.1-0.2 parts of rhizobium powder, 3-6 parts of zinc sulfate, 10-15 parts of diammonium phosphate, 5-9 parts of calcium dihydrogen phosphate, 15-20 parts of pigweed cakes, 15-20 parts of rice bran, 10-20 parts of red pine wood sawdust, 10-14 parts of black walnut wood sawdust, 11-20 parts of lemon wood sawdust, 5-8 parts of oilseed straw powder and 14-19 parts of veronica linariifolia straw powder. The sustained / 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 sustained / 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 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 destroy 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 tea is not high. ...

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.
