Abstract

The invention relates to a universal slow release fertilizer for sugarcane, and scientifically proposes a slow release fertilizer formula, namely N:P2O5:K2O equals to 15:10:5, suitable for wide sugarcane producing areas in China according to a nitrogen, phosphorus and potassium application principle, the nutrient status of soil of the main sugarcane producing areas in China and a fertilizer requirement law of sugarcane. In the formula, the total nutrient content is 30%. The slow release fertilizer is prepared by mixing the following raw materials according to mass ratio: 310-326 kg of urea containing 46% of N, 0-82 kg of monoammonium phosphate containing 49% of P2O5 and 9% of N, 333-556 kg of calcium magnesium phosphate containing 18% of P2O5, 83kg of potassium chloride containing 60% of K2O, 8kg of a fertilizer inhibitor, 2kg of a fertilizer synergist and 25-182kg of fillers.

Description

technical field [0001] The invention relates to a universal sugarcane slow-release fertilizer, belonging to the technical field of slow-release fertilizers. Background technique [0002] Sugarcane is an important sugar crop in my country, with a long growth cycle, high production and high nutrient demand. There are two sources for sugarcane to absorb nutrients from the soil. One is the fertilization capacity of the soil itself, which is mainly affected by soil fertility and texture; the other is the supply by artificial fertilization. In modern sugarcane agriculture, artificial fertilization has become the most important measure for sugarcane production and high-yield and high-sugar cultivation. In the main sugarcane producing areas in my country, multiple fertilizations are required to meet the nutrients required for sugarcane production. Generally, the entire production period of sugarcane requires the application of basal fertilizer, seedling fertilizer, evil fertilizer,...
