Abstract

The invention relates to an agricultural microbial compound bacterial fertilizer, in particular to a method for producing a microbial compound bacterial fertilizer. The method is characterized in that activated sludge fermented by a fermentation plant during sewage treatment is used as matrix, molasses is added into the matrix as a culture medium, compound bacteria are grafted into the culture medium after adding water to ferment, then grass carbon is added into the culture medium, and the mixture is dried to form the compound bacterial fertilizer. The method realizes reutilization of sludge waste, and provides economic and efficient microbial sludge bacterial fertilizer for the development of green ecological agriculture.

Description

Technical field: [0001] The invention relates to agricultural microbial compound bacterial fertilizer, which is a kind of fertilizer with activated sludge as the main substrate, adding a certain amount of peat and molasses as raw materials, adding functional strains for fermentation and cultivation, and producing microbial compound fertilizer through granulation, drying, packaging and other processes. The method of bacterial fertilizer. Background technique: [0002] my country's existing cultivated land is about 120 million hectares (hm 2 ), with an annual demand of 150 million tons (t) of fertilizers, it is the world's largest fertilizer importer, nitrogen fertilizer producer and fertilizer user. Fertilizers play an important role in my country's agricultural production, but the extensive use of chemical fertilizers has caused soil compaction, decreased soil fertility, and reduced the quality of agricultural products. Therefore, there is an urgent need to develop more en...
