Disclosed is a sprayable nonwoven fiber weed barrier comprising an aqueous solution of nonwoven fibers and polymer binder. The aqueous solution can be directly sprayed onto the soil to suppress weed penetration through the soil. The sprayable nonwoven fiber weed barrier has a pore structure that allows water to penetrate into the soil, but curbs the growth of weeds.

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.

Disclosed is a liquid mulching agent composition, which is environmentally friendly due to use of seaweed, facilitates soil coating, and has high light blocking efficiency, making it possible to control heat retention and water content in the soil. The liquid mulching agent composition includes a seaweed extract, a first component including at least one selected from the group consisting of humic acid, fulvic acid, and charcoal, and a second component including at least one selected from the group consisting of sodium alginate, polyvinyl alcohol, keratin, and sodium silicate.
