Method for preparing organic fertilizer from sweet potato starch processing powder residues

Abstract

The invention provides a method for preparing an organic fertilizer from sweet potato starch processing powder residues. The method comprises the following steps: S1, preparing raw materials including sweet potato starch residues, corn straw powder, soybean meal, livestock manure, a fermentation inoculant, distillers' grains and wheatgrass; and S2, after the corn straw is completely leached, putting the corn straw into a crusher, and crushing the corn straw which is completely leached through the crusher. According to the method for preparing the organic fertilizer from the sweet potato starch processing powder residues, the sweet potato starch residues are fully utilized for producing the efficient high-quality biological organic fertilizer, absorption and utilization of crops are facilitated, circular economy can be developed, the production cost and the environment cost of enterprises are reduced, the quality and safety of agricultural products are improved, soil is improved, and the environment is protected; the method improves the safety of soil planting, increases the additional value of the fertilizer, is beneficial to improving the yield and quality of crops, has a good practical application effect on improving boron-deficient soil and planting boron-rich crops, and improves the utilization rate of the fertilizer.

Description

technical field [0001] The invention relates to the field of organic fertilizer preparation, in particular to a method for preparing organic fertilizer by using sweet potato starch processing powder slag. Background technique [0002] Organic fertilizers refer to carbon-containing materials that are mainly derived from plants and (or) animals and are applied to the soil to provide plant nutrition as their main function. They are processed from biomass, animal and plant waste, and plant residues to eliminate the Toxic and harmful substances, rich in a large number of beneficial substances, are the main nutrients for green food production, commonly known as farmyard manure, including various animal and plant residues or metabolites, such as human and animal manure, straw, animal residues, and slaughterhouse waste etc. In addition, it also includes cake fertilizer (rapeseed cake, cottonseed cake, bean cake, sesame cake, castor bean cake, tea seed cake, etc.); compost; This is ...
