Abstract

The invention belongs to the technical field of fertilizer, and provides a special controlled slow release fertilizer for dry land sugarcane. The special controlled slow release fertilizer comprises formulas of a base fertilizer type sugarcane controlled slow release fertilizer and a top dressing type sugarcane controlled slow release fertilizer, wherein the base fertilizer type sugarcane controlled slow release fertilizer is prepared by uniformly mixing 3% sulfur and resin coated urea, diammonium phosphate, potassium chloride, potassium silicate, magnesium sulfate, zinc sulfate and borax, the top dressing type sugarcane controlled slow release fertilizer is prepared by uniformly mixing 3% sulfur and resin coated urea, diammonium phosphate and potassium chloride, the base fertilizer type sugarcane controlled slow release fertilizer is applied one time as the ground fertilizer during the sugarcane planting stage, and the top dressing type sugarcane controlled slow release fertilizer is applied one time during the sugarcane tiller stage. According to the present invention, the nutrient combination is performed according to the soil nutrient characteristics and the nutrient absorption regularity of the sugarcane in the dry land sugarcane region, and the sulfur and resin coated urea is adopted to control the nitrogen release, such that the requirements for the nutrient by the sugarcane at different periods are met, the sugarcane growth is significantly promoted, the adverse influence on the environment due to improper nitrogen fertilizer application is reduced so as to achieve comprehensive benefits of yield increasing, fertilizer saving and labor saving.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special controlled-release fertilizer for sugarcane in dry land. Background technique [0002] Sugarcane (Sugarcane) is the main sugar crop in my country. It is widely planted in tropical and subtropical regions of my country and plays an irreplaceable role in promoting economic development and social stability in production areas. Sugarcane is a C4 crop, which has the characteristics of long growth period, high yield, and high nutrient consumption. It is an economic crop that requires a large amount of fertilizer. Studies have shown that each ton of sugarcane needs to absorb 1.5-2.0 kg of nitrogen (N) from the soil, phosphorus (P 2 o 5 ) 1.0~1.5kg, Potassium (K 2 O) 2.0~2.5kg, fertilizer has become the most important means of production of sugarcane. However, for a long time, my country's dryland sugarcane (accounting for more than 90% of the total area of ...
