Abstract

The invention discloses a lychee release-control fertilizer and a preparation method thereof and belongs to the technical field of fertilizer preparation. The lychee release-control fertilizer comprises, by weight, 60 to 120 parts of coating material and 200 to 1200 parts of fertilizer granules; the lychee release-control fertilizer is prepared by steps of mixing, granulating, drying, cooling, coating and the like. The lychee release-control fertilizer has a moderate and stable release control speed, has balanced nutrition and is effective in reducing its loss rate, improving its availability and promoting healthy growth of lychee, lychee yield is averagely increased by 11.6% to 12.8%, and lychee sugar content is increased by 0.32% to 0.39%.

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-...
