Abstract

The invention discloses an industrial method for a bio-fertilizer inoculant by utilizing decayed cow dung as a raw material. The method comprises the following steps: proportioning, sterilizing, fermenting, drying and coating, wherein in the proportioning step, 20-70 parts by weight of decayed cow dung, 20-80 parts by weight of field soil, 2-10 parts by weight of rice bran, 2-10 parts by weight of bean pulp and 0-5 parts by weight of talcum powder are mixed; the pH value is regulated to 6.5-7.5 by using quick lime; and water the weight of which is 30-40% of the total weight of the raw materials is added, and then the materials are stirred evenly. The method has the advantages of wide raw material sources and less harsh fermentation conditions, thus being beneficial to industrial production on large scale. In the fermentation production process, no waste liquid is generated, and various wastes can be utilized, thereby meeting development of sustainable agriculture. The inoculant produced by using the method can be widely applied to various aspects and has an effect of obviously increasing the yield and quality of agricultural products.

Description

technical field [0001] The invention belongs to the technical field of agricultural biological fertilizer production, and relates to an industrial method for producing a biological fertilizer inoculant by using decomposed cow dung as a raw material. technical background [0002] In order to reduce the use of chemical fertilizers and the harm that chemical fertilizers bring to the environment. With the enhancement of environmental awareness, green agriculture is being actively developed at home and abroad. Many countries in Europe have generally used biological fertilizers, and the use of biological fertilizers has reached 45% to 60% of agricultural fertilizers, and the use of biological fertilizers in the United States has reached 60% to 70% of agricultural fertilizers. Biological fertilizers can not only effectively replenish soil organic nutrients, but also improve soil fertilizer and water retention capacity, reduce soil compaction and desertification, and are effective ...
