Crop straw organic fertilizer for tea tree planting

Abstract

The invention discloses a crop straw organic fertilizer for tea tree planting. The crop straw organic fertilizer is characterized by containing the following substances in parts by weight: 20-25 parts of rice hull ash, 25-30 parts of chicken manure, 15-20 parts of potassium chloride, 15-20 parts of ammonium nitrate, 9-11 parts of diammonium phosphate, 8-14 parts of calcium dihydrogen phosphate, 3-5 parts of calcium nitrate, 2-8 parts of potassium ore powder, 1-4 parts of rock flour, 3-6 parts of grass carbon powder, 2-8 parts of conch shell powder, 3-5 parts of white clamshell powder, 11-20 parts of venerupis philippinarum shell powder, 10-13 parts of talcum powder, 25-30 parts of urea and 15-20 parts of calcium superphosphate. The organic fertilizer disclosed by the invention contains inorganic nutrients, such as nitrogen, phosphorus, potassium and the like, and is also provided with a large number of microelements and organic matters, so that the fertilizer effect is remarkable, the tea disease can be alleviated, the cost is low, the economic benefit is high, and then, the application prospect is huge.

Description

technical field [0001] The invention relates to a crop straw organic fertilizer for planting tea trees. Background technique [0002] There are many types of fertilizers currently used for tea tree 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. 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 ...
