Embodiment Construction

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0039] A degradable liquid mulch, the main components of which include hydrophobically modified polymer materials.

[0040] The polymer material is chitin, polycarbonate, alkyl glucoside, cocoyl glucoside, cellulose acetate, carboxymethyl cellulose.

[0041] The hydrophobically modified polymer material is a polymer material modified by esterification, etherification, hydroxyalkylation, graft copolymerization or crosslinking.

[0042] Hydrophobizing agents for hydrophobic modification of polymer materials are long-chain alkanes or aromatics.

[0043] Hydrophobizing agents are specifically carboxylic acids, epoxy compounds, halogenated hydrocarbons, aliphatic acid chlorides, isocyan...

Abstract

The invention discloses a degradable liquid mulching film and a preparation method thereof, belonging to the field of agricultural mulching films. The main components of the degradable liquid mulching film provided by the invention comprise a hydrophobically-modified high polymer material. The whole mulching film material exists in a liquid form and can be directly sprayed on soil to form a film in use; and since the hydrophobically-modified high polymer material is adopted, the whole mulching film can be degraded, the erosion resistance of the mulching film can be improved, and water retention and soil moisture conservation of the soil are realized; and meanwhile, the mulching film can be directly sprayed to form a film along with the sowing of the seeds, so the labor intensity of farmers is greatly reduced, and use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural mulch, in particular to a degradable liquid mulch and a preparation method thereof. Background technique [0002] Faced with such a severe land form in our country, the use of plastic mulch to plant crops has become a common method used by farmers; the use of plastic mulch cultivation technology to meet crop heat preservation, moisture conservation, maintain fertility, and increase production and income has become one of the top ten in the world today. One of the agricultural extension and application technologies. In the past few decades, traditional agricultural plastic mulches have made great contributions to the adjustment of my country's agricultural industry structure and the increase of crop production and income. With the adjustment of my country's agricultural industrial structure and the promotion of agricultural technology, the use of plastic film to increase crop production and i...
