Multifunctional degradable liquid mulch film, production method and uses thereof

The invention provides a multi-functional degradable liquid mulching film which comprises the materials with the following weight percentage: a polymer of polyether glycol-polyvinyl alcohol-polyaspartate: 15.0 percent to 40.0 percent, an emulsifier: 1.0 percent to 5.0 percent, a disperse speader: 0.5 percent to 5.0 percent, a pH value regulator: 0.1 percent to 5.0 percent, an antifreeze: 1.0 percent to 5.0 percent, and water as the rest; after the mulching film being watered and sprayed on soil surface, the macromolecules thereof are combined with soil particles and a layer of black curing film can be formed on the soil surface rapidly which can restrain the soil water from vaporizing and prompt the soil to absorb more solar energy, thereby improving the earth temperature. The liquid mulching film completely degrades into a humic acid organic fertilizer, water and carbon dioxide which can be absorbed by crops; the degradation products effectively accelerate the formation of soil grain clusters; and the number of grain clusters with water stability is increased by 10 percent to 15 percent and the volume weight of soil can be decreased by 5 percent to 10 percent. If sprayed on the surface of sandy soil, the liquid mulching film can effectively slow down the infiltration of the water to reserve water, thereby saving the water consumption of irrigation. The liquid mulching film can replace plastic mulching films in a certain range and has a certain social meaning and market prospect.
