Abstract

The invention discloses a preparation method of an organic fertilizer, comprising the following steps: S1, respectively airing crop waste and poultry excrement, the uniformly mixing, then adding mixedamino acid and fermentation preparation to perform aerobic fermentation, and after fermentation is completed, smashing, screening and drying to obtain a fermentation product; S2, adding functional microbial bacteria and sodium carboxymethyl cellulose to the fermentation product, uniformly mixing, and pelleting, drying, cooling and screening to obtain prefabricated material A; S3, adding additivessuch as ammonium nitrate, calcium-magnesium-phosphate fertilizer, diammonium phosphate, sodium carboxymethyl cellulose and modified charcoal to the fermentation product, uniformly mixing, pelleting,drying, cooling and screening to obtain prefabricated material B; and S4, uniformly mixing the prefabricated material A with the prefabricated material B, thus obtaining the organic fertilizer. The organic fertilizer prepared according to the invention not only can provide nutrients needed by growth of crops, but also can increase the fertilizer utilization rate and improve the soil environment.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a preparation method of organic fertilizer. Background technique [0002] Although traditional inorganic chemical fertilizers have high nutrient content and rapid fertilizer effect, their fertilizer effect is strong but not long-lasting, and the effect of improving soil is not great, and even has side effects of destroying soil properties. The large-scale use of inorganic chemical fertilizers in agricultural production will bring such as Various problems such as quality decline, soil compaction, and water pollution. With the improvement of people's living standards, residents' demand for safe, hygienic and pollution-free organic and green food continues to increase. The majority of farmers urgently need to use organic fertilizers to improve the market competitiveness of agricultural products. [0003] There are many types of chemically synthesized fertilizers cur...
