Abstract

The invention discloses a soil conditioner for preventing and treating tobacco bacterial wilt as well as a preparation method and application thereof, and belongs to the technical field of biologicalprevention and treatment of plant diseases. The soil conditioner is prepared from the following components in parts by mass: 15-25 parts of a folium ginkgo fermentation product, 20-30 parts of an artemisia argyi rhizome fermentation product, 40-60 parts of a marigold rhizome fermentation product and 5 parts of tea leaf after-soaking residue. The soil conditioner is applied to soil in multiple times before tobacco planting, the soil acidification degree can be effectively improved, the number of actinomycetes in the soil can be increased, and the technical purpose of effectively controlling tobacco bacterial wilt is achieved.

Description

technical field [0001] The invention relates to a soil conditioner, which belongs to the technical field of biological control of plant diseases, in particular to a soil conditioner for preventing and treating tobacco bacterial wilt and its preparation method and application. Background technique [0002] Tobacco bacterial wilt is one of the main diseases of tobacco. It is a systemic infection caused by Ralstonia solanacearum. Once the tobacco plant is infected, the whole plant often dies. The harm is devastating. This often results in significant economic losses to tobacco production. The pathogenic bacteria of tobacco bacterial wilt mainly survives the winter in the soil along with plant residues, and can also survive the winter in seeds or other hosts in the field. The soil with bacteria, diseased tissues and organic fertilizers containing bacteria are the main initial invasion of the disease. The source of infection, the spread of the disease mainly depends on irrigatio...
