Special fertilizer composition for tea and preparation method of special fertilizer composition

Abstract

The invention discloses a special fertilizer composition for tea and a preparation method of the special fertilizer composition. The special fertilizer composition is characterized by being prepared from the following raw materials in parts by weight: 12-14 parts of ammonium nitrate, 9-11 parts of potassium sulphate, 3-5 parts of potassium chloride, 1-2 parts of sodium selenite, 2-3 parts of zinc sulfate, 12-14 parts of sepiolite, 8-10 parts of ground vermiculite, 2-3 parts of copper sulfate, 0.1-0.2 part of diethyl aminoethyl hexanoate DA-6, 0.1-0.2 part of brassinolide, 7-9 parts of ground calcium carbonate, 3-5 parts of sodium metasilicate, 15-20 parts of a soil conditioner, 2-3 parts of tea-seed oil and a defined amount of water. The special fertilizer composition is wide in applicable range, convenient to use and is rich in nutrient, and is capable of effectively increasing the yield. The special fertilizer composition realizes the organic combination of the soil conditioner, medium trace elements and a quick-acting inorganic fertilizer, and meets the requirement of growth of the tea. Meanwhile, the sepiolite and the ground vermiculite are also added to play roles in improving the soil and slowly releasing the fertilizer. The special fertilizer composition is reasonable in formula, balanced in nutrient, and safe without pollution, completely meets the demands on the nutrient in short-long periods of tea trees, is capable of balancing the fertilizer application, improving the soil and protecting the environment, and is also capable of effectively improving the yield and the quality of the tea.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and relates to a special fertilizer composition 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 cannot be achi...

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
