Example 1
The application utilizes the method to carry out a comparative test to test the disinfection and disinsection effects of the method. The method comprises the following specific steps:
1. preparing three storage cabinets with the same numbers of 01, 02 and 03 respectively;
2. putting the same amount of culture medium soaked with Aspergillus niger and the same amount of Toxoplasma chinensis into the three storage cabinets respectively, and sealing;
3. the humidity of the three storage cabinets is adjusted to 50% -55% by using the system; adjusting the temperature to 25-30 ℃;
4. the oxygen content of the 01 storage cabinet is controlled to be below 1% by utilizing the system; controlling the oxygen content of the 02 storage cabinet to be below 1%, and adding cassia oil for fumigation; only adding cassia oil with the same quantity as that of the 02 cabinet into the 03 storage cabinet for fumigation;
5. monitoring the fumigation effect in the cabinet, wherein the fumigation lasts for 24h, and recording the result.
The result is: the visual inspection shows that the diameters of the mold fungi of 01 and 03 are increased compared with the diameters of the mold fungi in the 02 storage cabinet; the three are placed in an incubator for cultivation, and the observation of a microscope shows that 85% of mould in the 02 storage cabinet is inactivated, which is the best, and the 03 storage cabinet is slightly better than the 02 storage cabinet, but the difference is not obvious; the booklice in the storage cabinet No. 01 die in all 4 days; all the booklice in the No. 02 storage cabinet die in 1 day; the booklice died in the storage cabinet No. 03 in 5 days. Therefore, by adopting the composite fumigation method of the low-oxygen environment and the fumigant, the fumigation time is shortened, and the working efficiency is improved.
Example 2
The method is used for carrying out a comparative test, and the disinfection and insect killing effects of the temperature on the method are tested. The method comprises the following specific steps:
1. preparing three storage cabinets with the same numbers of 01, 02 and 03 respectively;
2. putting the same amount of culture medium soaked with Aspergillus niger and the same amount of Toxoplasma chinensis into the three storage cabinets respectively, and sealing;
3. the humidity of the three storage cabinets is adjusted to 55% by using the system; the oxygen content is controlled below 1 percent;
4. controlling the temperature of the 01 storage cabinet at 10 ℃ by using the system, and adding cassia oil for fumigation; controlling the temperature of a 02 storage cabinet at 20 ℃, and adding equivalent cassia oil for fumigation; controlling the temperature of a 03 storage cabinet at 30 ℃, and adding equivalent cinnamon oil for fumigation;
5. monitoring the fumigation effect in the cabinet, wherein the fumigation lasts for 24h, and recording the result.
The result is: by observing that the diameters of bacterial plaques in the three storage cabinets are not obviously changed, wherein the mould in the storage cabinet 01 is not changed greatly, about 15% of mould in the storage cabinet 02 is inactivated, and about 90% of mould in the storage cabinet 03 is inactivated, and the reason for the phenomenon is analyzed that when the temperature is lower, the killing effect of the low-oxygen compound fumigation on the mould is poor, and the mould is slowly increased, so that the mould in the storage cabinet 01 is not changed greatly, the low-oxygen compound fumigation effect is enhanced along with the increase of the temperature, and the mould killing effect is obvious; the booklice in the storage cabinet No. 01 die 90% in 10 days; all the booklice die in the No. 02 storage cabinet within 7 days; the booklice died in the storage cabinet No. 03 in 1 day. The results show that the fumigation efficiency can be improved and the treatment time can be shortened by increasing the temperature.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the scope of the present invention, and therefore, all equivalent technical solutions should fall within the scope of the present invention.
