Plastic mulching technology is widely used in agricultural technology. But the plastic film is difficult to decompose in the natural environment, scattered in the soil and the natural environment, destroy the soil structure, causing white pollution of the soil and the environment. Studying degradable plastics has become the key to solving this problem.
Multifunctional degradable liquid mulch is modified by lignite, weathered coal or peat to papermaking black liquor, seaweed waste liquor, winemaking waste liquor or starch waste liquor, and is formed by the action of crosslinker through lignin, cellulose and polysaccharide. Polymer compounds are obtained by mixing with various additives, silicon fertilizers, trace elements, pesticides and herbicides. There are three innovations, namely, the emperor and the more salt, the Xiasha private, the moxibustion, the moxibustion, the smoke, the moxa, the moxa, the moxa, the moxa, the moxibustion, the moxa, the moxibustion, the moxa, the moth, the salt, the salt, the cents, and the mountains. kitchen Wo? ãž contempt Ho Hing?

From the perspective of actual promotion and application, the effect was very satisfactory. At present, the scientific and technological departments have formally included the achievements in the implementation of the national implementation plan for resource-saving technology demonstration cities and continue to expand farmland application demonstration in agricultural areas.
Biodegradable liquid film entering the demonstration farm for the control of "white pollution" to find a shortcut
Qingdao Municipal Science and Technology project supported by special programs, Shandong University of Science and Technology's commitment to "multi-functional biodegradable liquid film research and application of" agricultural research recently into the demonstration phase, for the control of traditional plastic mulch "white pollution" to find a shortcut. Jiaonan is expected next year will build an annual output of 10,000 tons scale multi-functional biodegradable liquid film production base.
