Polylactic acid has achieved remarkable results in desertification control!

In chaogewenduer Town, wulatehou banner, Bayannaoer City, Inner Mongolia, aiming at the problems of serious wind erosion of the exposed wound surface of the degraded grassland, barren soil and slow plant recovery, researchers have developed a rapid recovery technology of degraded vegetation induced by microbial organic mixture. This technology uses nitrogen fixing bacteria, cellulose decomposing microorganisms and straw fermentation to produce organic mixture, Spraying the mixture in the vegetation restoration area to induce the formation of soil crust can make the sand fixing plant species of the exposed wound of the degraded grassland settle down, so as to realize the rapid repair of the degraded ecosystem.
This new technology is derived from the national key research and development plan “desertification degraded grassland control technology and demonstration” project, which is also one of the many innovative achievements made since the implementation of the project. The project, led by Inner Mongolia University, is jointly implemented by 20 universities, scientific research institutes and local grassland stations, including the Chinese Academy of Sciences, the Chinese Academy of Agricultural Sciences, Beijing Normal University and mengcao group.
In view of the problems that the vegetation on the exposed wound surface of severely desertified grassland is scarce and the plant seeds cannot be fixed, the project has developed the “hybrid technology of mechanical sand barrier and biological sand fixation of new materials for rapid treatment of severely desertified grassland”. This technology uses long sandbags made of low-cost and easy-to-operate biodegradable polylactic acid materials to set up a grid type mechanical sand barrier, combined with the sowing technology of Artemisia ordosica seeds in the sand barrier, It solves the problem of fixing seeds on quicksand and can be used for rapid restoration of severely sandy grassland.
