Embodiment 1

[0023] Get Bacillus subtilis XF-1 dry powder (content 20 * 10 8 cfu / g) 10 parts by weight and 2 parts by weight of ginkgo polysaccharide powder are uniformly mixed, and stored at room temperature in a vacuum-sealed bag. Detect the quantity of Bacillus subtilis wherein after 3 months, be 16 * 10 8 cfu / g, the mortality rate was 4%. The mortality of Bacillus subtilis XF-1 dry powder alone after storage for 3 months was 12%.

[0024]This shows that Ginkgo polysaccharide has no significant effect on the activity of Bacillus subtilis, and also has a certain protective effect.

Embodiment 2

[0026] Get Bacillus subtilis XF-1 dry powder (content 20 * 10 8 cfu / g) 10 parts by weight and 3 parts by weight of ginkgo polysaccharide powder were uniformly mixed, and stored at room temperature in a vacuum-sealed bag. Detect the quantity of Bacillus subtilis wherein after 3 months, be 14 * 10 8 cfu / g, the mortality rate is 9%, which shows that excessive ginkgo polysaccharides have a certain impact on the activity of Bacillus subtilis, but still have a certain protective effect.

Embodiment 3

[0028] Get Bacillus subtilis XF-1 dry powder (content 20 * 10 8 cfu / g) 10 parts by weight and 1 part by weight of ginkgo polysaccharide powder are uniformly mixed, and stored at room temperature in a vacuum-sealed bag. Detect the quantity of Bacillus subtilis wherein after 3 months, be 16 * 10 8 cfu / g, the mortality rate is 12%, which shows that the amount of ginkgo polysaccharide has a certain influence on the protective effect of Bacillus subtilis.

Abstract

One embodiment of the invention relates to an application of a bacillus subtilis preparation in prevention and treatment of cruciferae clubroot. The bacillus subtilis preparation contains bacillus subtilis and ginkgo polysaccharide. The gingko polysaccharide and the bacillus subtilis preparation are mixed for application for the first time, side effects on the bacillus subtilis preparation are avoided, the control effect on the clubroot of cruciferae can be effectively improved, and production and income are increased.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to the application of a bacillus subtilis preparation in the prevention and treatment of cruciferous clubroot. Background technique [0002] Clubroot of cruciferous crops is a worldwide disease caused by Plasmodiophora brassicae Woron. The disease mainly harms the roots of plants, and is usually susceptible to both the seedling stage and the adult plant stage, and is mainly susceptible to the seedling stage. Usually the seedlings are damaged, and in severe cases, the seedlings die, and the yield is severely reduced, or even the harvest is not harvested; once the field is polluted by clubroot, the soil will be infected for a long time, which seriously threatens the sustainable production of cruciferous crops. In recent years, the incidence of P. brassicae has become more and more serious all over the world, especially in Asia, Northern Europe, Australia, North America and...
