Description

Plastic film laying device for soil fumigation Technical Field The utility model belongs to the technical field of soil plastic film laying, and particularly relates to a plastic film laying device for soil fumigation. Background Soil fumigation is a soil disinfection method in agricultural production, also called soil disinfection, and utilizes the action of high temperature and chemical substances to kill or reduce harmful organisms such as bacteria, ova and weed seeds in soil, and the main purpose of the soil fumigation is to protect crops and improve yield. After fumigating soil, plastic films are required to be paved on fumigated soil, toxic gases of a fumigating agent are enabled to diffuse in the soil, germs are killed, when the fumigated soil is paved with the plastic films, corresponding plastic film paving devices are required to be used, but certain defects still exist in the actual use process of the existing plastic film paving devices, because when the fumigated soil is paved with the plastic films, the whole soil needs to be coated, and when the plastic films are paved with the common plastic film paving devices, two adjacent plastic films cannot be well connected, and the joint of the two plastic films cannot be well covered with the soil, so that gaps exist between the paved different plastic films, the fumigated soil cannot be comprehensively coated, and the film coating effect is reduced. Disclosure of utility model The utility model provides a plastic film laying device for soil fumigation, and aims to solve the problem that the existing plastic film laying devices are poor in laying effect.
