Biofertilizer for promoting growth of tea trees

Abstract

The invention discloses a biofertilizer for promoting the growth of tea trees. The biofertilizer contains the following substances in parts by weight: 25-30 parts of potato straw powder, 30-40 parts of highland barley straw powder, 15-20 parts of horse bean straw powder, 5-10 parts of conch shell powder, 5-9 parts of white clamshell powder, 9-14 parts of dicalcium phosphate, 3-6 parts of calcium phosphate, 3-5 parts of potassium nitrate, 2-6 parts of ammonium nitrate, 1-2 parts of calcium nitrate, 10-15 parts of rapeseed cake meal, 15-20 parts of soybean cake meal, 0.001-0.003 part of bacillus thuringiensis powder, 0.001-0.003 part of aschersonia powder and 0.001-0.003 part of bacillus thuringiensis powder. The biofertilizer has the beneficial effects that the fertilizer disclosed by the invention is rich in a variety of nutrients, such as organic fertilizers, inorganic fertilizers and the like, is free from toxicity, side effects, residues and drug resistance and does not pollute the environment, so that the growth of tea is facilitated, nutritional ingredients required by the tea can be supplemented obviously, the quality of the tea is improved, the content of substances, beneficial to human bodies, in the tea is increased, and the soil can be improved.

Description

technical field [0001] The invention relates to a biological fertilizer for promoting the growth of tea trees. Background technique [0002] The purpose of tea tree planting is to pick tea greens and make dry tea. The growth process of tea trees in a lifetime can be roughly divided into three years before planting to promote the growth of seedlings and three years after planting to pick tea greens. For young tea trees in the first three years of planting, early rooting and rapid development are the focus of tea farmers' management and protection. As far as fertilization is concerned, on the one hand, it is necessary to meet the nutrient needs of young tea trees and promote the rapid growth of young tea trees. On the one hand, according to the fact that tea gardens are mostly reclaimed from low hills and barren hills, and the soil organic matter and beneficial microorganisms are low, organic fertilizers and beneficial microorganisms should be added to achieve fertilization an...

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.

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
