Slow-release organic fertilizer for tea leaves and preparation method thereof

Abstract

The invention relates to a slow-release organic fertilizer for tea leaves and a preparation method thereof. The slow-release organic fertilizer is characterized by being prepared from the following raw materials in parts by weight: 40-45 parts of vinegar residues, 12-15 parts of rice hull ash, 20-25 parts of kaoline, 4-6 parts of mica powder, 12-16 parts of potassium chloride, 2-3 parts of ammonium molybdate, 1-2 parts of zinc sulfate, 1-2 parts of copper oxide, 3-4 parts of magnesium oxide, 10-12 parts of quartz sand powder, 3-4 parts of polyacrylamide, 5-8 parts of silkworm excrement, 15-20 parts of a soil conditioner, 4-6 parts of epoxidized soybean oil and a proper amount of water. According to the slow-release organic fertilizer for the tea leaves, the organic fertilizer contains inorganic nutriments such as phosphorus and potassium and further contains large numbers of microorganisms and organic matters, the polyacrylamide has a controlled release action to a fertilizer effect and is suitable for the growth of tea trees, and the quality of the tea leaves is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and relates to a tea slow-release organic fertilizer 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 achieve...

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
