Special fertilizer for sugarcane and preparation method of fertilizer

Abstract

The invention discloses a special fertilizer for sugarcane. The fertilizer comprises the following raw materials in parts by weight: 300-500 parts of plant ash, 100-200 parts of peanut bran, 600-1,000 parts of fermented animal dung, 5-10 parts of potassium dihydrogen phosphate, 10-20 parts of potassium nitrate, 3-5 parts of borax, 8-15 parts of manganese sulfate and 6-10 parts of zinc sulfate. A preparation method of the fertilizer comprises the following steps: performing pile fermentation on the fermented animal dung and the plant ash for 3-6 months; crushing a fermented product and the peanut bran into powder with the particle size of 200-300 microns; fully mixing the obtained powder, potassium dihydrogen phosphate, potassium nitrate, borax, manganese sulfate and zinc sulfate to obtain a mixture; granulating the prepared mixture by a granulator to obtain granular substances; drying the prepared granular substances at 80-100 DEG C, and storing granule shapes to obtain the finished fertilizer.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a special fertilizer for sugarcane and a preparation method thereof. Background technique [0002] 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 fertilizer, which cannot meet the growth needs of sugarcane, especially in Guangxi. In the area, the soil is relatively poor. 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, restricting the normal growth of sugarcane, and affecting sugarcane. Increased production. [0003] When people fertilize sugarcane, they generally use chemical fertilizers, urea, manure and other raw materials to topdress sugarcane. Although the effect is good, the nutrient...

[0002] 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 fertilizer, which cannot meet the growth needs of sugarcane, especially in Guangxi. In the area, the soil is relatively poor. 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, restricting the normal growth of sugarcane, and affecting sugarcane. Yield increase

[0003] When people fertilize sugarcane, they generally use chemical fertilizers, urea, manure and other raw materials to topdress sugarcane. Although the effect is good, the nutrients contained in chemical fertilizers and urea are far from meeting the nutritional needs of sugarcane. Yellow leaves, small leaves, slow growth, small sugarcane, light weight, poor disease resistance, easy to suffer from leaf spot, and more prone to various diseases and insect pests. The sugarcane area has only paid attention to the application of nitrogen fertilizer for many years. The supplement of trace element fertilizer is very little. At the same time, micro-fertilizer is added to compound fertilizer as base fertilizer, which is difficult to promote in production due to its high cost and poor fertilizer efficiency. Go yield and sugar low
