Abstract

The invention discloses a sugarcane controlled release fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer preparation. Raw materials of the sugarcane controlled release fertilizer comprise, by weight, 50-150 parts of a coating material and 200-1200 parts of fertilizer particles, and the sugarcane controlled release fertilizer is prepared through the steps of crushing, extracting, filtering, concentrating, fermenting, granulating, drying, cooling and packaging. The sugarcane controlled release fertilizer has the advantages of moderate and stable controlled release rate, balanced nutrition, effective reduction of the loss rate of fertilizers, promotion of rapid and healthy growth of sugarcane, improvement of the output of the sugarcane, effective prevention of diseases and pest damages, soil environment improvement and ecology and environmental protection maintenance.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a sugarcane controlled-release fertilizer and a preparation method thereof. 【Background technique】 [0002] Sugarcane is an important sugar-producing crop, and its planting area is particularly large in Guangxi, my country. The annual sucrose production accounts for about 70% of the total sugar production in the country. However, the sugarcane growth process has the characteristics of large fertilizer consumption, and the one-time fertilization amount should not be too much, and the fertilizer will cause the phenomenon of "burning roots", so a small amount of fertilization method is usually used for fertilization. [0003] At present, some people have begun to study sugarcane fertilizer. For example, the patent literature (patent number: ZL200710066326.4) discloses a special compound fertilizer for sugarcane, including base fertilizer and topdressing...
