Special fertilizer for tea

Abstract

The invention discloses special fertilizer for tea, and belongs to the technical field of compound organic fertilizer. The special fertilizer for tea is prepared from the following raw materials in parts by weight: 20-28 parts of amino acid fertilizer, 24-28 parts of organic fertilizer, 40-50 parts of azophoska, 2-7 parts of humic acid and 0.1-0.3 part of borax. The amino acid fertilizer is prepared through fermentation or hydrolysis of bean pulp and rapeseed dregs, the bean pulp is subjected to hydrolysis to prepare an amino acid solution, and the rapeseed dregs is subjected to fermentation to prepare a rapeseed dreg fermentation product; the amino acid fertilizer is prepared through blending of the amino acid solution and the rapeseed dreg fermentation product at the mass ratio of (0.3-0.6) to 1; the organic fertilizer is prepared through fermentation of livestock manure; the azophoska is prepared from the following components in parts by weight: 5-15 parts of monoammonium phosphate,17-27 parts of urea and 8-18 parts of potassium sulphate. The disease resistance and cold resistance of a tea tree are remarkably improved by applying the fertilizer, the weights of one hundreds of buds are increased, and the yield of tea can be increased by 18% around.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, in particular to a special fertilizer for tea. Background technique [0002] There are many types of fertilizers currently used for tea tree planting. Among them, most of the special fertilizers for tea are NPK compound fertilizers available on the market. It is 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, easily cause soil compaction and soil hardening, thereby affecting the growth of tea trees, and the promotion effect on the growth of tea trees is not obvious. [0003] At the same time, although simple organic fertilizers are rich in organic matter, the release of nutrients is slow, the absorption of tea trees is slow, the fertilizer efficiency is low, and effective balance cannot be reached between various effective nutrients.
