The invention belongs to the technical field of mulching films and particularly discloses a liquid-state mulching film and preparation and use methods thereof. The main technical scheme is as follows: the preparation and use methods comprise the steps of taking sludge, and adding a sterilizing agent prepared from water-dissolved trichloroisocyanuric acid, so as to deodorize and sterilize; then, adding humic acid raw powder, inorganic salts and water, mixing, stirring and homogenizing, then, grinding and reacting, so as to prepare a master batch formed by a paste body; taking polyacrylamide and derivatives thereof, lignosulfonate or / and cellulose derivatives, so as to form a sub-material with film forming, penetration, dispersion, chelation and water retention properties; during use, dissolving the sub-material by water, adding the dissolved sub-material into the master batch, stirring to prepare a porridge-like body, then, adding water, uniformly stirring and diluting, and spraying by a mist sprayer, thereby forming the mulching film. The liquid-state mulching film is prepared in a manner that the sludge serves as a main material, so that the problem of sludge treatment is basically solved, especially, the waste is changed into the valuable, and the land capability can be greatly increased; the liquid-state mulching film has the functions of increasing temperature, preserving soil moisture and promoting crop growth, the elimination of white pollution is realized, the flying dust factor of agriculture is controlled, the soil is improved, water resources are conserved, the revenue of farmers is increased, the expenditure of farmers is reduced, and the sustainable development of agriculture is promoted.

The invention provides a production method for a fish oil microcapsule product with ultrafine edible fungus powder as a main wall material. Main materials for microcapsule encapsulation are ultrafine mushroom and tremella powder and perilla oil used as a deodorization substance for fish oil. The production method comprises the following steps: preparation of the ultrafine mushroom and tremella powder; preparation of composite fish oil; and preparation of a fish oil microcapsule. The prepared fish oil microcapsule product has a pure white color and good appearance and can effectively encapsulate a core material. The product has strong antibacterial activity, effectively inhibits fishy smell of the fish oil, supplements and reinforces the function of unsaturated fatty acid of the fish oil and has the excellent characteristics of water solubility, thickening performance, gelatinization, film formation, etc. The wall material of the fish oil microcapsule becomes a nutrition component for the product and enriches nutritional functions of the fish oil product.
