である。However, in the above-mentioned prior art, since the injected chemical solution is turned into harmful gas in the soil, in order to prevent the harmful gas from coming out of the surface, after the chemical solution is injected. The soil disinfecting machine is configured so that the surface of the soil is covered with the mulch film entirely and the end portion of the mulch film is pushed into the soil by the pushing disk. When the mulch film covered with and the mulch film covered in this step are overlapped and pushed by the pushing disc, it is difficult to pass the pushing disc again by tracing the groove formed in the previous step. However, it is impossible to reliably hold and sandwich the multi-film. In addition, since the force for sandwiching and holding the mulch film is particularly weak during the operation under strong wind, the mulch film is easily peeled off and the effect of soil disinfection cannot be sufficiently obtained. Also, if the mulch film peels off, the harmful gasified chemical liquid will leak,
In the case of a field close to a residential area, it may cause a pesticide pollution, such as a bad odor and a bad feeling especially in the vicinity. Therefore, the present invention is to form a soil disinfecting device capable of reliably overlapping and holding the mulch film covered in the previous step with the mulch film covered in the present step, and reliably holding and holding the mulch film. It is the purpose.
