Abstract

The invention discloses a ful- degradable liquid mulch film, taking renewable and cheap natural macromolecule humic acid, lignin and waste slag as main raw material, containing no artificial macromolecule monomer in burdening. The product is characterized by good thermal insulating, and water retention function, low cost, environment- friendly, and adjustable degradating time about 30-120 days according to different requirement. The invention is characterized in that: it effectively overcomes problem of hard degradation for normal plastic mulch film, and it can fully degrade under natural environment, and the final product is soil humic acid fertilizer and carbon dioxide and there is no harm component residual.

Description

technical field [0001] The invention relates to a fully degradable liquid mulch film and a preparation method thereof. Background technique [0002] According to the data from the Ministry of Agriculture, the area of ​​arable land suitable for plastic film covering in my country is 550 million mu, and since 1994, it has grown at an annual rate of about 10 million mu. [0003] The use of plastic mulch cultivation technology is one of the top ten agricultural technologies well known in this century. The application of plastic film can meet the needs of crops for heat preservation, moisture conservation, frost protection, and fertility maintenance. It is one of the main applications of plastics in agriculture. In the early 1950s, Japan was the first to promote the application of plastic film mulching cultivation technology. my country introduced this technology from Japan in 1978. Since the 1980s, the use of plastic film has shown an upward trend in fluctuations. In 1981, the...
