Long-acting fertilizer special for sugarcane and preparation method thereof

Abstract

The invention discloses a long-acting fertilizer special for sugarcane and a preparation method thereof. The long-acting fertilizer special for sugarcane is prepared from, by weight, 12-14 parts of large granular urea, 36-42 parts of acrylic resin-coated urea, 22-24 parts of potash fertilizer, 5-7 parts of water soluble phosphate fertilizer, 15-21 parts of weak-acid-soluble phosphate fertilizer and 0.5-1.5 parts of chelation type medium trace element fertilizer. The prepared long-acting fertilizer special for sugarcane is used as a base fertilizer for application, the requirements for nutrients of various growing periods of sugarcane can be met, labor can be saved, and soil acidification and hardening can also be avoided.

Description

technical field [0001] The invention relates to the technical field of fertilizer production. More specifically, the invention relates to a special fertilizer for long-acting sugarcane and a preparation method thereof. Background technique [0002] The growth period of sugarcane is generally 10-12 months, and the growth cycle is relatively long. The demand for nitrogen, phosphorus and potassium in the whole growth period is very large. 22-24kg of nitrogen, 9-10kg of phosphorus and 16-18kg of potassium; 24-26kg of pure nitrogen, 10-11kg of phosphorus and 18-20kg of potassium are needed to produce 7-8 tons of sugarcane per mu. However, the proportion of sugarcane's nutrient requirements in each growth period is inconsistent. The amount of fertilizer required in the seedling stage of sugarcane accounts for about 10% of the total amount of fertilizer required, 10%-20% in the tillering stage, more than 60% in the elongation stage, and 10%-20% in the mature stage. %, showing the...

AI Technical Summary

Problems solved by technology

However, the fertilization mode of one-time base fertilizer is easy to lead to nutrient loss and low utilization rate. The nitrogen fertilizer is only 15%-30%, the phosphorus fertilizer is only 8%-15%, and the potassium fertilizer is only 30%-40%. The fertilizer effect period is short and common in the market. The effective period of sugarcane fertilizer is up to 60 days, which cannot meet the nutritional needs of sugarcane at all stages of growth.

Moreover, ordinary sugarcane fertilizers on the market only focus on nitrogen, phosphorus, and potassium, and do not consider the supplementation and scientific combination of trace elements such as calcium, magnesium, sulfur, silicon, zinc, and boron, resulting in lower fertilizer utilization rates and more soil acidification and hardening problems. Seriously, the quality of sugarcane planting has also declined significantly
