Fertilizer special for tea tree

Abstract

The invention discloses a fertilizer special for tea tree, which relates to the composite fertilizer technical field. The fertilizer special for tea tree comprises a coating layer and fertilizer particles in the coating layer, the fertilizer particle comprises 2-3 parts of nitrogenous fertilizer, 2-3 parts of phosphate fertilizer, 10-15 parts of decomposed fermentation silkworm excrement and 10-15 parts of molasses alcohol broth; the coating layer is a slow release carrier, the slow release carrier comprises stearic acid, an adhesive and mineral powder. The fertilizer special for tea tree can provides the trace element such as nitrogen element, phosphor element and potassium element which are required by growth of tea tree, abundant amino acid, humic acid and organic matter in the molasses alcohol broth are used for improving and supplementing nutrition for the soil, can promote the rapid growth of new leaf of the tea tree; the fertilizer particle is coated in the coating layer, the fertilizer is slowly released, so that loss rate of the fertilizer is effectively reduced, the use ratio of the fertilizer is increased, the slow release carrier is composed of stearic acid, the adhesive and mineral powder which are graded, so that white pollution is not generated.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a special fertilizer for tea trees. Background technique [0002] As a crop with high economic benefits, tea trees are widely planted in southern China. However, with the widespread planting of tea trees, the demand for fertilizers for tea trees has increasingly become a bottleneck for the growth and cultivation of tea trees; Fertilizers mostly use nitrogen, phosphorus and potassium compound fertilizers available on 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 period of time. Many farmers use these compound fertilizers excessively in order to increase tea production. Fertilizer, such long-term use will damage the soil aggregate structure, and easily cause soil compaction, soil hardening and salinity, which will affect the growth of tea trees and reduce the quality of tea; The r...
