Abstract

The invention discloses a special-use nano water-soluble fertilizer for sugarcane and a preparation method thereof. The water-soluble fertilizer is composed of the following components: 15%-20% urea,10%-15% of monopotassium phosphate, 9%-15% of potassium sulfate, 10%-15% of biochemical fulvic acid, 5%-10% of nano carbon, 5%-10% of chelated multi-element nutrient elements, 2%-5% of compound sodiumnitrophenolate, 2%-5% of sodium dodecyl benzene sulfonate, 1%-5% of sodium salicylate, 1%-3% of magnetic nano ferroferric oxide and 1%-3% of mesoporous silica. The water-soluble fertilizer is prepared by mixing bioactive substances such as macroelements, chelated multi-element nutrient elements, a surfactant, a plant regulator, nano carbon, a nano coating agent, magnetic nano ferroferric oxide and mesoporous silica, and is a multi-element compound fertilizer capable of promoting large-scale popularization of water and fertilizer integration.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special nanometer water-soluble fertilizer for sugarcane and a preparation method. Background technique [0002] Water-soluble fertilizer has excellent characteristics such as flexible formula, comprehensive nutrient, rapid effect, high nutrient utilization rate, and economic and safe application. However, the research on water-soluble fertilizer for sugarcane is relatively backward compared to other crops. In recent years, the popularization and application of sugarcane water-fertilizer integration technology has developed rapidly, but due to the unclear fertilization parameters, it is difficult to synchronize sugarcane fertilizer and water requirements. "Large formula, small adjustment" regional fertilization technology and precision irrigation technology integrated water and fertilizer integration precision fine irrigation and fertilization technology will be an inevitable tr...
