Abstract

The invention relates to a fertilizer, and particularly relates to a biological bacterial fertilizer. The biological bacterial fertilizer is prepared from fermenting raw materials and a strain activating solution through a solid fermentation technology, wherein the effective viable count of the strain activating solution is 4-30 hundred millions / mL; the volume mass ratio of the addition amount of the strain activating solution to the fermenting raw materials is 1-5 L / 100kg; the fermenting raw materials include the following components in parts by mass: 30-50 parts of grape skin, 30-50 parts of spent mushroom compost, 10-20 parts of furfural residues, 3-6 parts of plant ash and 0.2-0.8 part of inorganic salt; the solid fermentation process comprises the following steps: mixing the fermenting raw materials; adding the strain activating solution to the mixed raw materials; uniformly stirring, and then flatly spreading in solid fermentation equipment for fermentation; and drying to obtain the biological bacterial fertilizer. The biological bacterial fertilizer prepared by adopting a solid fermentation mode is high in effective viable count and high in strain competitive force and solves the problems of strain storage and inactivation in use of the traditional biological bacterial fertilizer.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a biological bacterial fertilizer prepared by solid fermentation technology and its application. Background technique [0002] Traditional biological bacterial fertilizers are mostly prepared by simply mixing liquid bacterial liquid or solid bacterial powder with organic materials, and their production is mostly produced by liquid submerged fermentation, followed by spray drying. This production method requires high equipment, and the equipment Expensive, complex operating parameters, not suitable for large-scale applications, and liquid fermentation can not use organic waste, production is subject to certain limitations. [0003] Every year, a large amount of agricultural organic waste is wasted in our country, causing great environmental pressure. It has become an inevitable development trend to carry out harmless treatment and resource utilization of organic waste. In my country, the research ...
