Abstract

The invention discloses an active auxiliary added into compound fertilizer and a preparation method thereof. The active auxiliary added into the compound fertilizer is medium and small molecule organic matter, oligosaccharide, fulvic acid, surface active agent and the like which are extracted from sugarcane bagasse and peanut cake. The active auxiliary added into the compound fertilizer also can protect cultivated land and improve and activate soil when being continuously used. According to the invention, in a production technical process of the compound fertilizer, active substances are added, properties of the compound fertilizer are improved, and growth condition of crops is adjusted and soil properties are improved, so that the crops can absorb more nutrients, less nutrients are fixed in the compound fertilizer, utilization efficiency of the compound fertilizer is improved, and pollution of the compound fertilizer to the environment is reduced. Development of novel fertilizer and high-efficiency fertilizer auxiliary is one important measure for increasing grain yield, improving utilization rate of fertilizer and reducing environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer production, and in particular relates to a compound fertilizer added with an active auxiliary agent and a preparation method thereof. Background technique [0002] Among the chemical fertilizers applied to the soil, only a small part can be absorbed and utilized by crops, and a large part cannot be absorbed by crops. Generally, the seasonal utilization rate of nitrogen fertilizer is 30% to 50%, and that of phosphorus fertilizer is 20%. ~30%, potassium fertilizer is about 50%, and fertilizers that cannot be absorbed and utilized by crops will volatilize, leaching, and fix in the soil. According to estimates, the national agricultural investment in chemical fertilizers is about 400 billion yuan a year. Fertilizers Excessive and unscientific application of fertilizers has resulted in a decline in the benefits of increasing fertilizer production and a serious waste of resources. Whether i...
