Abstract

The invention discloses a controlled-release fertilizer for a tea tree and a preparation method thereof, belonging to the technical field of preparation of fertilizers. The controlled-release fertilizer for the tea tree comprises the following raw materials by weight: 60 to 140 parts of a packaging material and 200 to 1400 parts of fertilizer granules. The controlled-release fertilizer for the tea tree is prepared by comprising the steps of mixing, stirring, granulating, drying, cooling, packaging, etc.. According to the invention, controlled-release rate of the fertilizer is moderate and stable; nutrition is balanced; the loss rate of the fertilizer can be effectively reduced; utilization efficiency of the fertilizer is improved; healthy growth of the tea tree is promoted; and an average yield of tea leaves is increased by 14.8% to 15.6%.

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...
