Performance test
Detection of the kill rate of microorganisms in a substrate
The microbial killing rate of the substrates in application examples 1-5 and comparative examples 1-4 was tested, the contents of bacteria, fungi and actinomycetes in the substrates were measured by plate dilution method, and the microbial culture media were beef extract peptone medium, martin bangladesh medium and gao shi i medium.Weighing 10g of soil sample (or matrix sample) and placing in 90mL of sterile water, placing on a constant temperature shaking table (28 ℃) and shaking for 15min at the rotating speed of 120r/min, and then preparing on an ultra-clean workbench to obtain the soil sample (or matrix sample) with the concentration of 10-1~10-4CFU/g suspension, 0.1mL of suspension at various concentrations was pipetted onto the surface of the medium at a bacterial concentration of 10-3、10-4Suspension of CFU/g with a concentration of 10 for fungi-1、10-2Suspension of CFU/g, 10 for actinomycetes-3、10-4CFU/g suspension was spread evenly on solid medium using a triangular glass spatula, with 3 replicates per sample. Culturing the smeared culture medium in a constant-temperature incubator, culturing bacteria at 30 ℃ for 1d, culturing fungi at 28 ℃ for 2d, and culturing actinomycetes at 28 ℃ for 5 d. Recording was started when uniform colonies grew on each medium.

The calculation results are shown in Table 1.
TABLE 1
From table 1, the following conclusions can be drawn:
as can be seen from the data of the application examples 1-5 and the comparative examples 1-4, the disinfection method of the substrate 8 in the application can have good disinfection effect on various substrates 8, so that the microbial killing rate of the substrate 8 is greatly improved;
comparing the data of application example 3 with the data of comparative example 1, it can be seen that the substrate sterilization method of the present application by the apparatus of the present application helps to improve the sterilization effect of the substrate 8, and it is worth mentioning that the sterilization method of the present application enables the operator to inhale as little volatile substances such as formaldehyde solution as possible, thereby helping the health of the operator. And the data of the comparative example 2 are combined, so that when the substrate 8 is disinfected by manually spraying disinfectant such as formaldehyde solution, the concentration of the formaldehyde solution is improved, the disinfection effect of the formaldehyde solution can be improved, but in order to achieve the disinfection effect similar to that of the application, the concentration of volatile disinfectant such as the formaldehyde solution needs to be improved, the disinfection cost of the substrate 8 is invisibly increased, and the physical health of operators is not facilitated.
By comparing application example 3 with comparative example 3, the concentration of the formaldehyde solution cannot be so large that the effect of disinfecting the substrate 8 is reduced. Comparing the data of application example 3 and comparative example 4, it was found that it is necessary to seal the entire substrate 8 and drip irrigation tape 5, and if not, the formaldehyde solution is rapidly volatilized, thereby causing a decrease in the effective ingredient acting on the substrate 8, and thus deteriorating the sterilizing effect of the formaldehyde solution on the substrate 8.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
