Problems solved by technology
However, due to the fact that most of the above-mentioned experiments place the samples directly in the matrix, with the extension of the experiment time, the samples cannot be recovered effectively and completely, resulting in large errors in the experimental data, or directly causing some indicators to be unable to be measured.

The invention discloses a recycle method for plastic thin film in liquid and soil. The method comprises the steps that the plastic thin film is laid on adjustable grid meshes, two frames are fixed through magnets, and the plastic thin film is clamped between the two adjustable grid meshes; the frames and the plastic thin film in the frames are placed into dug soil, an appropriate amount of bacteria liquid is added to the surface of the plastic thin film, and then the surface of the plastic thin film is buried with soil; according to the time designed by experiments, the soil is dug, the framesare taken out, the plastic thin film in the frames is recycled, the possibility of man-made damage to samples due to excavation is greatly lowered in the excavation process, the recycle rate of experimental materials is greatly increased at the same time, and the experimental errors are greatly reduced.
Description
technical field [0001] The invention relates to a recycling method for experimental materials, in particular to a recycling method for plastic films in soil. Background technique [0002] Agricultural mulch film has the functions of heat preservation, moisture retention, insect resistance, disease prevention, and weed suppression. It can maintain soil moisture, improve water use efficiency, alleviate the problem of soil water shortage in arid and semi-arid areas, and improve the growth environment of crops at the same time, which is conducive to crop growth and development. , Improve crop yield and agricultural benefits, so plastic film is widely used, however, agricultural film residues will cause serious "white pollution" problems to the agricultural ecological environment. Not only that, in modern life, all kinds of plastic products such as polystyrene, polypropylene, polyvinyl chloride and polyethylene are discarded after use and thrown away at random. Among them, variou...
