Abstract

The invention provides a high-activity compound microbial fertilizer. The high-activity compound microbial fertilizer is prepared from the following raw materials in parts by weight: 5-20 parts of corn steep liquor fermentation liquor; 30 to 60 parts by weight of corn slurry; 10 to 30 parts by weight of molasses; 10 to 30 parts by weight of mineral elements; 4-10 parts by weight of sugar alcohol calcium; and 0.5-5 parts by weight of trace elements. Compared with the prior art, the high-activity compound microbial fertilizer provided by the invention adopts components with specific contents, realizes better interaction, is comprehensive in nutrition, high in bacterial colony number, high in activity and long in shelf life, can effectively solve the problems of soil hardening and low phosphorus and potassium absorptivity caused by excessive application of chemical fertilizers, improves the utilization rate of the fertilizer, and reduces the production cost. The product yield is obviously improved.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizer preparation, and more particularly, to a highly active compound microbial fertilizer and a preparation method thereof. Background technique [0002] Corn steep liquor is a by-product of the production of corn starch by the wet process. When producing corn starch, the purified corn needs to be soaked in water and then dehydrated, and then soaked in 0.30%-0.5% sulfite solution for 60h-70h, the soaking liquid is corn slurry, during the soaking process corn soluble nutrients such as soluble Protein, free fatty acids, soluble sugars and vitamins all enter the corn steep liquor, so corn steep liquor is rich in nutrients. After testing, corn steep liquor contains 24.7% organic matter, 6.6% total nutrients and 1.17g / L sulfur, which is a natural microbial fermentation medium. [0003] Compound microbial fertilizer is a kind of living microbial fertilizer that is composed of specific microorg...
