Abstract

The invention provides a special fertilizer for sugarcane and a preparation method of the fertilizer. The fertilizer comprises the following raw materials in parts by weight: 400-440 parts of fused urea, 10-30 parts of humic acid, 100-145 parts of monoammonium phosphate, 30-45 parts of potassium chloride, 100-135 parts of potassium sulfate, 50-62 parts of dolomite dust, 2-3 parts of magnesium sulfate, 1-2 parts of zinc sulfate and 2-3 parts of polyaspartic acid. The invention provides the fertilizer which can satisfy the absorptive amount of sugarcane on various nutrients and improve the output and stress resistance of sugarcane, and the production is increased by over 15% compared with common composite fertilizers. The fertilizer further can promote absorption of nutrients by sugarcane to improve the utilization ratio of effective components in the fertilizer, so that the use level of chemical fertilizer is reduced by over 20%. Furthermore, the fertilizer can improve the crop quality and is environmental friendly, sugarcane is good in taste and high in quality, and the commercial performance of sugarcane is remarkably improved.

Description

technical field [0001] The invention relates to chemical fertilizers, in particular to a special fertilizer for sugarcane and a preparation method thereof. Background technique [0002] Fertilization for traditional sugarcane planting is to apply decomposed farmyard manure or commercial organic fertilizer per mu before planting, and then apply ordinary commercial fertilizer. After ordinary commercial fertilizers are applied to cultivated land, part of them will be transpired, dissipated and lost with water, part of them will be fixed and utilized by soil and soil microorganisms, and only part of them will be absorbed and utilized by crops. Studies have shown that: the utilization rate of urea and ammonium bicarbonate is 20% to 46%, phosphate fertilizer (diammonium, monoammonium, heavy calcium) is 10% to 25%, and potassium fertilizer is 45% to 60%. It can be seen that the utilization rate of ordinary fertilizers is very low. [0003] The growth period of sugarcane is long, ...
