由“白色革命”带来的“白色公害”,可望结束。我国光·生物降解塑料农用地膜经过“七五”、“八五”10年的研究和实验,技术已走向成熟。 据悉,目前我国参与研制和开发这项技术的单位已有数10家。其中北京高分子材料科技开发公司中试研究所,较好地解决了地膜厚度、透光性能和机械强度等技术难题,取得了突出成果。在新疆、黑龙江、北京、天津、山东、河北等产棉区大面积推广应用,地膜60天后逐渐消失。 光·生物降解塑料农用地膜是最新石油制品,以其不污染环境、节能、制造成本低、使用面广而被世界厂商看好。美、法、日等国拥有此项技术而垄断着数10亿美元的国际市场。 据试验,它能使作物适合生长的地球纬度提高2
The “white pollution” brought about by the “white revolution” is expected to end. China’s light and biodegradable plastic agricultural plastic film has undergone research and experiments during the “7th Five-Year Plan” and “Eighth Five-Year Plan”. The technology has matured. It is reported that at present, China has participated in the development and development of the technology of 10 units. Among them, the Beijing Institute of Polymer Materials Science and Technology Development Co., Ltd. has successfully solved technical difficulties such as film thickness, light transmittance and mechanical strength, and achieved outstanding results. In Xinjiang, Heilongjiang, Beijing, Tianjin, Shandong, Hebei and other cotton production areas to promote the use of large areas, the film gradually disappeared after 60 days. Light biodegradable plastic Agricultural plastic film is the latest petroleum product, which is favored by the world’s manufacturers for its non-polluting environment, energy saving, low manufacturing cost, and wide application. The United States, France, Japan, and other countries own this technology and monopolize the international market of several billion U.S. dollars. According to experiments, it can increase the latitude of the earth suitable for growing crops by 2
