Abstract

The present disclosure specifically relates to a preparation method for a degradable liquid-state mulching film by using livestock manure as a raw material, including pulverizing and sieving the dried livestock manure, followed by mixing with water to form a slurry; mixing the slurry with a stabilizer, an inorganic material and water to form a homogeneous suspension, followed by mixing with a surfactant, a grafted monomer mixture, a plasticizer and water to form a pre-emulsified mixed liquid; and finally raising a temperature of the pre-emulsified mixed liquid and adding an initiator under stirring to react to obtain a liquid-state mulching film. The mulching film obtained in the present disclosure not only has the functions of temperature raising, soil moisture conservation and grass controlling, but also has a strong adhesion ability to cause top soil particles to form an ideal agglomerate structure.
