Abstract

The invention discloses a sclerotium rolfsii solid fermentation culture medium and an application thereof. The solid fermentation culture medium comprises a solid substrate and water, wherein the solid substrate comprises wheat bran and agricultural wastes, the wheat bran accounts for 20%-60% of the total weight of the solid substrate, and the weight ratio of the water to the solid substrate is (20-45):100; and the agricultural wastes select rice husk, sweet sorghum straw, an organic fertilizer, a wheat bran substrate, vinegar residue, wine lees, garden dead twigs or sawdust. The sclerotium rolfsii solid fermentation culture medium prepared by the preparation method disclosed by the invention is low in cost, the preparation process is simple, and a herbicide prepared by adopting the solid fermentation culture medium can be preserved at room temperature.

Description

technical field [0001] The invention relates to a solid fermentation medium for Sclerotinia sclerotiorum, in particular to a solid fermentation medium for Sclerotinia sclerotium using agricultural waste and bran as raw materials and an application thereof. Background technique [0002] The continuous application of chemical herbicides has exposed many disadvantages. The development and utilization of microorganisms, especially plant pathogenic fungi, for weed control is an effective, safe, environmentally friendly and sustainable weed management method. To investigate, isolate and use weed pathogenic bacteria for biological control is a hot spot in weed research in the world. Since S. sclerotiorum of the genus Sclerotinia (Sclerotinia spp.) can cause rapid plant disease and kill a variety of broad-leaved weeds at the same time, it has been screened for development as a biological herbicide for lawn control Dandelion (Taraxacum officinale), thistle (Cirsium arvense) and othe...
