Abstract

The invention relates to a special medium-concentration slow release fertilizer for sugarcanes. The slow release fertilizer contains nitrogen, phosphorus and potassium according to the ratio that nitrogen: phosphorus: potassium equals 20: 10: 5. The special medium-concentration slow release fertilizer disclosed by the invention can effectively improve the emergence rate, tillering rate and plant height of the sugarcanes and significantly improve the agricultural yield and sugar yield of the sugarcanes; tests prove that the yield per unit of the sugarcanes and the sugar yield of the sugarcanes are improved; and the quality of the sugarcanes is obviously improved, and the special medium-concentration slow release fertilizer is more suitable for being applied to soil with medium-concentration fertilizers in sugarcane areas in tropical and sub-tropical regions in southern China.

Description

Technical field: [0001] The invention relates to agricultural fertilizers, in particular to a medium-concentration slow-release fertilizer specially used for sugarcane. 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, and 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, ...
