Special compound fertilizer for sugarcane

Abstract

The invention relates to the technical field of agricultural fertilizers, in particular to a special compound fertilizer for sugarcane. The ratio of N to P2O5 to K20 in the compound fertilizer is (23-26) to (7-11) to (18-24). According to the compound fertilizer, aiming at the characteristic of poor soil in Guangxi, the contents of N, P2O5 and K20 in soil are increased, and the defects of low sugarcane yield, low sugar content and low benefit due to blind fertilization can be effectively overcome, so that the sugarcane yield is increased, the income level of sugarcane farmers is increased, and the stability and development of Guangxi pillar industry are promoted; the fertilizer is applied in a two-section manner, so that the out-dated production habits of the farmers in the past is changed, the enthusiasm of the sugarcane farmers in promoting development by science and technology is guided, and the productivity level of sucrose industry is continuously increased.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special compound fertilizer for sugarcane. Background technique [0002] Sugarcane is the main raw material for sugar production in my country. In the world's total sugar production, sucrose accounts for about 65%, and our country accounts for more than 80%. Sugar is one of the necessary food for human beings, and it is also an important raw material for food industries such as candy and beverages. Sugarcane is suitable for planting in places with fertile soil, sufficient sunlight, and large temperature differences between winter and summer. Sugar cane is a temperate and tropical crop that is used as a raw material for the manufacture of sugar and for ethanol as an energy substitute. There are more than 100 countries producing sugar cane in the world, and the largest sugar cane producing countries are Brazil, India and China. [0003] The normal growth of su...

Problems solved by technology

[0003] The normal growth of sugarcane has its own rules for the needs of various nutrients. At present, most of the fertilization of sugarcane in production is about 25% to 40% compound ginseng and mixed fertilizer, which cannot meet the growth needs of sugarcane, especially in the In Guangxi, the soil is relatively barren. Most users fertilize according to their habits, rather than scientific fertilization according to physiological needs and soil fertilizer supply capacity. As a result, they cannot meet the growth needs of sugarcane, which restricts the normal growth of sugarcane and affects Increased sugar cane yield
