Method for reducing content of pathogenic bacteria in soil for strawberries

Abstract

The invention discloses a method for reducing a content of pathogenic bacteria in soil for strawberries. The method specifically comprises the following steps: before planting is performed, B1619 is uniformly sprinkled into planting ditches according to a using amount of 6 g / plant, a 1.25% brown sugar aqueous solution is poured according to a standard of 1500 kg per mu, solar hot water with temperature of 62-68 DEG C is poured according to a standard of 15 L / m<2>, and after seedlings are survived, B1619 is applied to roots of plants according to a using amount of 4 g / plant; or Chongchakexing and Tugai are uniformly mixed according to a ratio of 1:1, the mixed material is applied to holes according to a standard of 1.5 kg per mu before planting is performed, and a brown sugar aqueous solution with a concentration of 1.25% is poured according to a standard of 1500 kg per mu. The method disclosed by the invention is organic and environmentally friendly, and can effectively reduce the pathogenic bacteria in the soil for growth of the strawberries, especially a content of actinomycetes, verticillium and fusarium, thereby reducing diseases caused by the bacteria.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a method for reducing the content of strawberry soil pathogens by treating the soil for planting strawberries. Background technique [0002] Soil contains a large number of pathogenic microorganisms. They can cause soil-borne diseases and insect pests such as root rot, wilt, bacterial wilt, anthracnose, viral diseases and nematode diseases of strawberries. Sheng Ruyuan conducted research on strawberry root rot, which has become more and more serious in recent years. Through field disease sample collection and pathogenic bacteria isolation, a total of 105 strains were obtained. According to morphological observation, six genera were preliminarily identified, which are Fusarium spp., Pythium spp., Rhizoctonia solani., Phytophthora spp., Pestalotiopsis clavispora, Sclerotinia sclerotiorum. However, Cao Kuirong and others isolated the pathogenic bacteria of strawberry root ...

Problems solved by technology

[0003] At present, common methods to reduce soil pathogenic bacteria include crop rotation, high-temperature stuffy shed, or through selection of stress-resistant varieties and transplantation of varieties. The use of chemical agents to reduce soil pathogenic bacteria is the most commonly used method, but chemical agents are harmful to humans and do not conform to modern organic methods. The development concept of agriculture, so the use of organic and environmentally friendly methods is the demand for the development of modern agriculture
