A method for reducing the content of pathogenic bacteria in strawberry soil

Abstract

The invention discloses a method for reducing the content of pathogenic bacteria in strawberry soil. The method is specifically: before planting, B1619 is evenly sprinkled into planting ditch holes at an amount of 6 grams per plant, and then poured with 1.25% brown sugar according to the standard of 1500 kg per mu. Aqueous solution, then according to 15L / m 2 The standard perfusion of 62 ~ 68 ℃ solar hot water, live seedlings in the amount of 4 g / plant B1619 applied to the root of the plant. Or evenly mix the heavy stubble nemesis and soil reform in a ratio of 1:1, apply in holes uniformly according to the standard of 1.5kg per mu before planting, and then press the standard perfusion concentration of 1500kg per mu to be 1.25% brown sugar aqueous solution. The method is organic and environmentally friendly, and can effectively reduce the content of soil pathogenic bacteria that affect the growth of strawberries, especially the content of actinomycetes, verticillium and fusarium, thereby reducing diseases caused by these 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
