Problems solved by technology

[0009] The invention provides a controlled-release fertilizer for tea trees and a preparation method thereof to solve the problems of poor fertilizer controlled-release effect, low fertilizer utilization efficiency, and the use of a large amount of pesticides and chemical fertilizers, resulting in pesticide resistance of pests, soil compaction, and pollution of water source soil and crops , the quality of agricultural products has declined, and pesticide residues have exceeded the standard, causing food safety and other problems
The controlled-release rate of the fertilizer of the present invention is moderate and stable, and the nutrition is balanced, which can effectively reduce the loss rate of the fertilizer, improve the utilization efficiency of the fertilizer, promote the rapid and healthy growth of the tea tree, and increase the growth rate of the tea tree; the use of the fertilizer of the present invention can fundamentally solve the problem of long-term Excessive application of chemical fertilizers and chemical pesticides has caused problems such as decline in soil organic matter, soil compaction, poor air permeability, and increase in soil-borne diseases

Abstract

The invention discloses a tea tree controlled-release fertilizer and a preparation method thereof and belongs to the technical field of preparation of fertilizers. The tea tree controlled-release fertilizer comprises, by weight, 60-160 parts of a coating material and 200-1600 parts of fertilizer granules. The tea tree controlled-release fertilizer is prepared in the steps such as crushing, extracting, filtering, concentrating, fermenting, granulating, drying, cooling and coating. The tea tree controlled-release fertilizer has a moderate and stable controlled-release rate and balanced nutrition, fertilizer loss rate can be decreased effectively, fertilizer utilization is increased, quick and healthy growth of tea trees is promoted, and tea tree growth speed is increased; by using the fertilizer, the problems such as soil organics decline, soil caking, poor breathability and soil-borne disease increase caused by long-term over-application of chemical fertilizers and chemical pesticides are solved basically.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a controlled-release fertilizer for tea trees and a preparation method thereof. 【Background technique】 [0002] my country is a big tea-drinking and tea-growing country, and its annual output of tea ranks second in the world. Depending on the planting location and variety, tea trees can harvest 2-4 times a year, so it is necessary to maintain a continuous supply of nutrients, especially nitrogen fertilizer, during the growth of tea trees to keep the tea output at a relatively high level. high level. [0003] For this reason, some people have begun to study tea tree fertilizer at present. For example, the patent literature (application number: 93102872.8) discloses a special fertilizer for tea tree foliage, which contains 30%-55% urea, 5%-20% glucose, 10%-25% potassium salt, 10%-30 % zinc salts and antibiotics etc. [0004] At present, more compoun...
