Special organic/inorganic compound fertilizer for tea and preparation method thereof

Abstract

The invention relates to a special organic / inorganic compound fertilizer for tea and a preparation method thereof. The compound fertilizer is characterized by being prepared from the following raw materials in parts by weight: 500-600 parts of chicken manure, 40-50 parts of peat, 30-35 parts of urea, 50-60 parts of monoammonium phosphate, 30-35 parts of diammonium phosphate, 12-14 parts of potassium chloride, 1-2 parts of ammonium molybdate, 1-2 parts of zinc sulfate, 2-3 parts of ferrous sulfate, 3-4 parts of fermenting microbial inoculum, 10-12 parts of weathered coal, 0.1-0.14 part of diethyl aminoethyl hexanoate (DA-6), 12-14 parts of iron ore tailing, 6-9 parts of bamboo charcoal powder, 2-3 parts of soybean oil, 1-2 parts of eucalyptus oil and 15-20 parts of soil conditioner. By fermenting with the chicken manure, the compound fertilizer improves the soil fertility of a tea garden, increases the organic substances and improves the soil; and meanwhile, the formula contains macro, secondary and minor elements as well as slow-release components, and the fertilizer efficiency slowly releases, thus meeting the requirements of tea in the growth period and improving the quality and yield of tea.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and relates to a special organic-inorganic compound fertilizer for tea and a preparation method thereof. Background technique [0002] There are many types of fertilizers currently used for tea 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. [0003] 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...

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.

[0003] 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. The content of ingredients and trace elements is not high
