Abstract

The invention discloses a controlled-release fertilizer for lychee and a method for preparing the controlled-release fertilizer, and belongs to the field of technologies for preparing fertilizers. The controlled-release fertilizer for the lychee comprises, by weight, 50-150 parts of coating materials and 200-1600 parts of fertilizer grains. The method includes steps of smashing, extracting, filtering, concentrating, fermenting, granulating, drying, cooling, coating and the like to obtain the controlled-release fertilizer for the lychee. The controlled-release fertilizer for the lychee and the method have the advantages that the controlled-release fertilizer for the lychee is moderate and stable in controlled-release speed and is nutritionally balanced, the fertilizer loss rate can be effectively reduced, the fertilizer utilization efficiency can be improved, fast and healthful growth of the lychee can be promoted, and the growth speed of the lychee can be increased; the fertilizer is free of residues in agricultural products, accordingly, environmental pollution can be prevented, and pest and disease damage can be effectively prevented.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a litchi controlled-release fertilizer and a preparation method thereof. 【Background technique】 [0002] my country is the country of origin of lychees and the largest producer in the world. The cultivated area and output of lychees account for 81% and 70% of the world respectively. It plays an important role in the rural industrial structure of main lychee producing areas such as Guangdong, Guangxi, Fujian and Hainan. . Due to the high economic and nutritional value of the fruit, consumption has increased dramatically. For a long time, although litchi cultivation technology has been developed by leaps and bounds, most of the fruit growers use traditional fertilizers for fertilization. For example, the patent document (application number: 201010585728.7) discloses a special formula fertilizer for litchi trees, which includes 240-260 jin of urea, 290-...
