Description

Recovery device with strong agricultural residual film adsorption capability and use method Technical Field The invention relates to the technical field of mulching film recovery devices, in particular to a recovery device with strong agricultural residual film adsorption capacity and a use method thereof. Background The mulch film has the functions of warming and preserving soil moisture, preventing and controlling insect attack, inhibiting weed growth, promoting crop growth and the like, is important agricultural production data of high and stable yield, plays an extremely important role in modern agriculture, and the practical area of the agricultural mulch film in China is maintained above 1750 ten thousand hectares at present. However, the mulching film can remain in the soil for about 300 years, and along with the continuous increase of the dosage and the service life of the mulching film, a large amount of mulching film remaining in the soil is difficult to degrade, so that the soil is polluted and damaged, the soil structure is damaged, the seedling emergence of crops is influenced, the root growth is hindered, the yield of crops is reduced, large-area white pollution is formed, serious negative effects are brought to the agricultural ecological environment, and the mulching film becomes a prominent problem facing the green development of agriculture.
