Steam injection sterilization has been widely used to solve the problem of soil continuous cropping because of its pollution-free and high sterilization efficiency.

[0003] However, when steam is introduced into the continuously cropped soil for disinfection, both steam and hot air heat the soil, but steam alone will cause steam condensation to clog the soil pores. In addition, excessive condensation will cause soil aggregates to disintegrate into fine debris, thereby forming a soil structure with even smaller pores, which will ultimately affect the diffusion capacity of the steam, thereby affecting the heat and mass transfer efficiency of the steam, causing the steam disinfection effect to deteriorate.

[0036] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0037] First embodiment

[0038] Please refer to Figure 1 ,in, Figure 1 The schematic diagram of the structure of the first embodiment of a novel soil steam and hot air disinfection method provided by the present invention. The novel soil steam and hot air disinfection method comprises the following steps:

[0039] S1, first start the vertical electric heating steam generator 1 to transport steam through the three-way control valve 3 and the pipeline, then start the hot air blower 2 to heat the soil inside the pipeline;

[0040] S2. When steam and hot air are transported through the pipeline, the transport amount of steam and hot air is checked and controlled by using the flow meter 4 and the flow valve 5 on the pipeline;

[0041] S3, after the flow valve 5 in S2 controls the steam delivery flow, the steam and hot air delivery pipe 6 is used to deliver the steam to the disinfection pipe 7 inside the transparent soil tank 8.

[0042] The three-way control valve 3 is used to adjust the flow ratio and intermittent ratio of the steam flow and the hot air flow by adjusting and selecting the appropriate hot air ventilation time and ventilation ratio.

[0043] After the steam is introduced, the condensed water from the steam will block the soil pores, and the soil aggregates will also disintegrate into fine debris, forming smaller soil pores. In order to solve the above problems, the present invention intends to solve the problem of excessive condensed water by introducing hot air (hot air) through a hot air blower: that is, hot air has the function of heating and dehumidification, and the three-way control valve 3 is used to adjust the flow ratio (X:Y) and intermittent ratio (i.e. ventilation time ratio) of the steam flow (X) and the hot air flow (Y). By adjusting and selecting the appropriate hot air ventilation time and ventilation ratio, the high temperature of the hot air is used to reheat the excess condensed water in the pores into water vapor, which can dredge the soil pores, improve the diffusion and heating range of the steam, and thus improve the efficiency of steam disinfection.

[0044] In addition, during the process of introducing hot air, the uniformity of soil temperature distribution can be improved by reasonably regulating the hot air flow rate and ventilation time, ultimately achieving the goal of improving steam disinfection efficiency and providing a theoretical basis for efficient disinfection of continuously cropped soil.

[0045] The general procedure is to pass steam and hot air at the same time, or to pass steam first and then hot air, that is, to complete the above two processes by adjusting the flow ratio of steam flow and hot air flow and the steam-hot air intermittent ratio. Passing steam and hot air at the same time, or passing steam first and then hot air, can remove excess moisture in the soil pores, effectively increase the steam diffusion range and temperature distribution uniformity, and thus improve the steam disinfection heating efficiency.

[0046] Compared with the related art, the novel soil steam and hot air disinfection method provided by the present invention has the following beneficial effects:

[0047] The present invention provides a novel soil steam and hot air disinfection method. Using the novel soil steam-hot air disinfection method, the high temperature of the hot air can remove excess moisture in the soil pores, effectively improve the steam diffusion range and temperature distribution uniformity, thereby improving the steam disinfection heating efficiency. At the same time, the temperature of the hot air can also increase the soil temperature, thereby playing a sterilization role.
