Abstract

The invention discloses tea tree controlled release fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer preparation. The tea tree controlled release fertilizer is prepared from, by weight, 60-140 parts of wrapping materials and 200-1400 parts of fertilizer particles. The tea tree controlled release fertilizer is prepared through the steps of granulating, drying, cooling, wrapping and the like. The fertilizer is moderate and stable in controlled release speed, balanced in nutrition, and capable of effectively decreasing the fertilizer loss rate, improving the fertilizer utilization efficiency and promoting healthy growth of tea trees, and the average yield of tea leaves is increased by 13.6-14.2%.

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...
