The invention relates to a production process of a sugarcane slow release
fertilizer, belonging to the technical field of fertilizers. The production process adopts a
fertilizer wrapping
fertilizer process to prepare a wrapped fertilizer type efficient slow release fertilizer for sugarcane, the combination of three main
nutrient fertilizers of
nitrogen,
phosphorus and
potassium is realized, and a three-element compound fertilizer is formed; according to the nutritional requirement of the growth of sugarcane,
nitrogen fertilizer
urea serves as a core layer, a
potassium fertilizer serves as a middle layer, and a
phosphorus fertilizer serves as an outer layer; and when the sugarcane slow release fertilizer serves as a base fertilizer and is applied to soil together with sugarcane seeds, the sugarcane slow release fertilizer can meet the nutritional requirement of the sugarcane for the whole life, firstly, at the growth prophase, the
phosphorus fertilizer and the
potassium fertilizer are released to promote the
root growth and
tiller of the sugarcane, and at the growth
metaphase of the sugarcane, the
nitrogen fertilizer of the core layer is released to promote the great growth of the sugarcane. The sugarcane slow release fertilizer is applied once when the sugarcane is planted, and the whole
growing season does not need fertilization, so that the problems that the sugarcane is fertilized for many times, a lot of manpower and financial resources are consumed, and the sugarcane is low in yield and
sugar content at present can be effectively solved.
