Abstract

The invention discloses a controlled-release fertilizer for sugarcane and a preparation method thereof, belonging to the technical field of preparation of fertilizers. The controlled-release fertilizer for the sugarcane comprises the following raw materials by weight: 60 to 140 parts of a packaging material and 180 to 1200 parts of fertilizer granules. The controlled-release fertilizer for the sugarcane 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; rapid and healthy growth of the sugarcane is promoted; and the yield of the sugarcane is increased by 12.4% to 13.6%, and the content of sucrose is increased by 0.32% to 0.4%.

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...
