Fertilizer special for tea

Abstract

The invention discloses a fertilizer special for tea, and belongs to the technical field of compound organic fertilizers. The fertilizer is prepared from the following raw materials in parts by weight: 20 to 28 parts of amino acid fertilizer, 24 to 28 parts of organic fertilizer, 40 to 50 parts of nitrogen phosphorus potassium fertilizer, 2 to 7 parts of humic acid and 0.1 to 0.3 parts of borax, wherein the amino acid fertilizer is prepared by fermenting or hydrolyzing soybean meal and rapeseed meal; the amino acid fertilizer is prepared by mixing an amino acid solution and a rapeseed meal leavening according to (0.3 to 0.6) to 1; the organic fertilizer is prepared by fermenting living stocks; the nitrogen phosphorus potassium fertilizer is prepared from 5 to 15 parts by weight of mono-ammonium phosphate, 17 to 27 parts by weight of urea and 8 to 18 parts by weight of potassium sulfate. By adopting the fertilizer special for the tea, disease resistance and cold resistance of a tea tree are improved greatly, hundred-bud weight is increased, and the yield of the tea tree can be increased over 18 percent.

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 planting, among which the special fertilizer for tea is mostly NPK compound fertilizer available in the market, which 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] Simultaneously, although pure organic fertilizer is 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 among various effective nutrients.
