Problems solved by technology

[0002] Slow-release / controlled-release special fertilizer is a compound technology that can slow or control nitrogen in the soil by using nitrogen as large-grained urea, polypeptide urea, sulfur-coated urea and slow-controlled release long-acting agent compound technology. The fertilizer with medium nutrient release rate has the advantage of high nutrient utilization rate, obvious effect of increasing production compared with common fertilizer, less fertilizer application, and is being widely used. Compound controlled-release special fertilizers with a multi-technology combination that meet nutritional needs. The only slow-release / controlled-release fertilizers with a single technology are only used for ornamental plants such as flower seedlings due to their high prices. It is a special controlled-release compound fertilizer that releases nutrients according to the characteristics of nutrient requirements during the growth period of corn

Abstract

The invention relates to the field of chemical fertilizers, in particular to a compound controlled-release fertilizer special for spring corns and a production method of the compound controlled-release fertilizer. The compound controlled-release fertilizer special for spring corns is composed of the following components in parts by weight: 300-500 parts of nitrogenous fertilizer, 100-170 parts of phosphate fertilizer, 120-235 parts of potassic fertilizer, and 3-15 parts of a slow controlled release long-acting agent. The nutrient supply, the efficiency and the time of the compound controlled-release fertilizer special for spring corns are synchronized with the crop growth requirements, the special proportion of nitrogen, phosphorus and potassium of the special fertilizer in the soil for crops can be enhanced and the formula balanced fertilizing is achieved.
