Abstract

The invention discloses a sugar cane controlled-release fertilizer and a preparation method thereof, belonging to the technical field of fertilizer preparation. The sugar cane controlled-release fertilizer is prepared from the following raw materials in parts by weight: 60-140 parts of coating material and 180-1200 parts of fertilizer granule. The preparation method comprises the following steps: granulating, drying, cooling, coating and the like. The fertilizer has the advantages of moderate and stable controlled-release rate and balanced nutrients, is capable of effectively lowering the loss rate of the fertilizer, enhancing the fertilizer utilization efficiency and promoting the quick and healthy growth of the sugar cane, and enhances the sugar cane yield by 11.2-12.8% and the sucrose content by 0.28-0.36%.

Description

【Technical Field】 [0001] The invention belongs to the technical field of fertilizer preparation, and specifically relates to a sugarcane controlled-release fertilizer and a preparation method thereof. 【Background technique】 [0002] Sugarcane is an important sugar-producing crop. The planting area is particularly large in Guangxi, my country. The annual sucrose output accounts for about 70% of the total sugar production in the country. However, sugarcane has the characteristics of large consumption of fertilizer during the growth process, and the amount of one-time fertilization cannot be too much. The fertilizer will cause the phenomenon of "root burning", so a small amount of fertilization is usually used for fertilization. [0003] Some people have already begun to study sugarcane fertilizer. For example, the patent document (Patent No.: ZL200710066326.4) discloses a special compound fertilizer for sugarcane, including base fertilizer and top dressing, wherein the ratio of nitr...
