Hydrophobic degradable liquid mulching film and preparation method thereof

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...

[0005] 2) The influence of residual plastic film on crop growth

[0009] In order to solve the above problems, some scientists have proposed to use degradable liquid mulch to replace the above-mentioned plastic mulch. At present, many units and individuals at home and abroad have carried out research and application on degradable liquid mulch, but at present, this part of liquid mulch is generally used. Humic acid, cellulose, starch, ethyl cellulose, polyglutamic acid and other extremely hydrophilic materials, or polymeric polymer materials simply mixed with these hydrophilic materials, such materials basically cannot form a film, only Can say simple chemical coverage
