Abstract

A preparation method of a novel environmentally-friendly fertilizer comprises the following steps: (1) uniformly mixing an organic fertilizer, composite trace elements, polymerized amino acids, modified starch and modified attapulgite, blending the obtained mixture with water, and stirring the mixture and the water to obtain a mixed solution; 2, adding biomass carbon powder, fermentative compound bacteria, a soil structure conditioner and a slow release agent to the mixed solution, uniformly mixing the added substances and the mixed solution, and carrying out accumulating piling, circulating overturning and fermentation to obtain a fermented material; 3, drying the fermented material until the water content is 5% or below, and crushing the dried fermented material to obtain a powder; and 4, sending the powder into a granulator, and carrying out granulation molding to obtain the finished product. The environmentally-friendly fertilizer prepared in the invention solves the nutrient supply problem of crops and the heavy metal and organic pollution problem in the production process of agricultural products.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a preparation method of a novel environment-friendly fertilizer. Background technique [0002] At present, food safety accidents occur frequently. Farmers may also experience excessive heavy metals in the polluted land according to conventional planting methods. For example, a large number of heavy metals in Hunan rice have exceeded the standard recently, and the excessive heavy metals in the soil is the main cause. In addition, due to the long-term use of pesticides and chemical fertilizers, the content of artificial organic pollutants in the soil is getting higher and higher, and the phenomenon of agricultural environmental pollution and ecological imbalance in my country is becoming more and more serious. The yield and quality of crops are seriously affected, which in turn threatens the survival of human beings. The environment, the resulting pollution o...
