Abstract

The invention provides a streptomycesvinaceus-drappus microbial inoculum. The streptomycesvinaceus-drappus microbial inoculum uses an active bacteria culture prepared by liquid submerged fermentation or solid fermentation of an active strain of streptomycesvinaceus-drappus, of which the storage number is CGMCC No. 2664, as an active ingredient. A tentative name of the streptomycesvinaceus-drappus microbial inoculum is S506, and the streptomycesvinaceus-drappus microbial inoculum was submitted to the CGMCC for storage on 11st September, 2008. The preparation method comprises the following steps of: A, activation of the strain; B, preparation of liquid seeds of the streptomycesvinaceus-drappus; and C, liquid submerged fermentation of the streptomycesvinaceus-drappus. The invention also provides a novel process of 'liquid seed preparation and solid fermentation' which is favorable for the growth of the streptomycesvinaceus-drappus, and the novel process meets the technical requirements on high effective viable count, high spore production rate, light contamination of crossbred bacteria and short fermentation period. When the active streptomycesvinaceus-drappus is applied to the roots of vegetables, various root diseases, such as blight, root rot and root knot nematode disease, of vegetables can be effectively prevented and controlled, and the streptomycesvinaceus-drappus microbial inoculum has obvious effects of enforcing growth of root systems and degrading autopoisonous matters of root systems, so that the streptomycesvinaceus-drappus microbial inoculum has a wide application prospect in effectively solving the problem of continuous cropping obstacles which are commonly happed to vegetables, fruit trees, medicinal materials and the like.

Description

technical field [0001] The invention relates to an inoculant of Streptomyces brownus and a preparation method thereof, and belongs to the technical field of microbial fertilizers and fermentation engineering, in particular to the technical field of continuous cropping obstacle prevention and control preparations. Background technique [0002] Facility cultivation is one of the most important production methods of modern agriculture. While enriching people's food baskets, it also increases farmers' income. At present, the production of facility vegetables has become the second pillar industry of my country's planting industry, and the output value of facility vegetables accounts for more than 50% of the total output value of vegetables. Because protected cultivation has the characteristics of fixed facilities, difficulty in turning stubble, lack of rainwater leaching in facility soil, and lagging cultivation technology, with the extension of planting years, continuous croppin...
