Special organic fertilizer for tea trees

Abstract

The invention discloses special organic fertilizer for tea trees. The special organic fertilizer is prepared from raw materials in parts by weight as follows: 33-35 parts of pomace, 24-26 parts of sweet potato powder residues, 8-11 parts of reed, 4-5 parts of dextrin, 8-10 parts of lobster powder, 7-8 parts of ammonium chloride, 4-5 parts of potassium phosphate, 25-26 parts of coarse compost particles, 29-31 parts of sunflower stalk, 1.2-1.5 parts of dodecyl dimethyl betaine, 0.8-1.0 parts of tween 80, 19-20 parts of bentonite and an appropriate amount of water. The special organic fertilizer is prepared from the raw materials according to nutrient absorption features of the tea trees and integrates advantages of long effective period of organic fertilizer and rapid and high fertilizer efficiency of inorganic fertilizer, and meanwhile, the fertilizer prepared from a biochar framework is compact in grain shape, can be applied to a tea garden conveniently and cleanly, provides nutrient supply stably for a long time while improving soil structure and optimizing the growing environment of the tea trees, thereby overcoming defects of high time consumption and labor consumption for application of farm manure, increasing tea yield and improving tea quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special organic fertilizer for tea trees. Background technique [0002] With the increasing level of agricultural modernization, organic fertilizers are gradually replacing ordinary chemical fertilizers and becoming an important fertilizer in agricultural production. Organic fertilizers have many advantages such as complete nutrition, improved soil, and increased fertilizer utilization. However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is more effective th...

However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is more effective than ordinary chemical fertilizers, it is difficult to meet the nutrient needs of plants when they grow vigorously; fourth, fertilizers are bulky and inconvenient to transport and store; fifth, for special The soil environment such as acid-base, drought-humidity, soil lacking some elements and the nutrient requirements of specific crops are not effectively targeted
