The invention discloses a tebuconazole pesticide-degrading bacterium, a soil bioremediation bacterium based on the bacterium and application thereof, belonging to the field of biotechnology. Its taxonomic name is Serratia marcescens H2 (Serratia marcescens H2). This strain is a Gram stain negative bacterium, and it is preserved in the China Center for Type Culture Collection (CCTCC), and the preservation number is CCTCC NO: M 2016478 , date of deposit September 13, 2016. The Tebuconazole Pesticide Residue Degrading Bacteria is a strain with strong degrading ability to Tebuconazole isolated from the soil where Tebuconazole has been used for many years through enrichment culture. The strain grows with Tebuconazole as the only carbon source. In the liquid medium, the activity of the bacteria is increased through the induction of tebuconazole, and the degradation ability of the tebuconazole is improved. The preparation method of the bacterial agent is simple, the cost is low, and the application is convenient. It can be scattered on the soil, and the degradation effect in the soil can reach 88%. important meaning.

The present invention provides a method and device for measuring the water-saving potential of an irrigation area based on big data. The method not only considers the saving of water resources, but also ensures the balance of the ecological environment of the irrigation area and surrounding areas of the irrigation area, and protects the ecological environment and species diversity. The original hydrological cycle of the irrigation area and its surrounding areas has been maintained. By selecting dominant species around the irrigated area as a mark, while implementing agricultural irrigation and water-saving development in the irrigated area, determine and evaluate whether the water-saving technical model (irrigation parameters) implemented in the irrigated area is reasonable or not according to the growth of the dominant species around the irrigated area. It destroys the balance of the surrounding ecosystem and species diversity, etc., which can effectively avoid the destruction of the ecological balance of the irrigated area and surrounding areas and the impact on species diversity caused by excessive water saving, and realize the effective implementation of the water-saving technology model in the irrigated area. Based on the evidence, reasonable agricultural water-saving technologies and management models can be selected to better promote local economic development and protect ecological balance.

The invention discloses an endogenous biocontrol strain for inhibiting Acanthopanax blight and its application. The endogenous biocontrol strain is Bacillus sp. SC‑JW‑14, which is preserved in China Microorganisms Preservation Management The General Microbiology Center of the Committee, the preservation address is No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing, and the preservation number is CGMCC No.12921. The Bacillus sp. SC-JW-14 of the present invention can be used for the biological control of Acanthopanax blight, the antibacterial rate against Rhizoctonia solani can reach 69.6%, and the control effect can reach 59.4%. The present invention takes the pathogenic bacteria of Acanthopanax blight as the prevention and control object, isolates and screens the antagonistic endophytic strains existing in healthy plants Acanthopanax senticosus, lays the foundation for the biological control of Acanthopanax blight, and its rational application can reduce the number of chemical agents The environmental pollution caused is conducive to the protection of ecological balance, and can greatly improve and promote the artificial cultivation of Acanthopanax senticosus and the increase in income and production, which has certain research significance.
