由中国农科院土肥研究所、北京燕山石化公司研究院以及山东省青州市朱良镇政府等5家单位联合研制开发的液态地膜在山东省青州市正式面市。目前,第一批液态地膜共45吨已被农业部调往北京、甘肃、新疆等地投入应用。液态地膜为液体乳剂,由长链烃基分子组成。乳化后具有强烈的粘附能力,喷施地表后能迅速形成胶结薄膜,将土粒联结成理想的团聚体,从而提高地温,抑制土壤水分蒸发,使农作物生育期不仅提前,而且平均
By the Chinese Academy of Agricultural Sciences Institute of Soil and Fertilizer, Beijing Yanshan Petrochemical Company Research Institute and Qingliang City, Shandong Province Zhu Liangzhen government jointly developed five units of liquid film in Qingzhou City, Shandong Province officially available. At present, the first batch of 45 tons of liquid film has been transferred to the Ministry of Agriculture in Beijing, Gansu, Xinjiang and other places put into use. Liquid film is a liquid emulsion, composed of long-chain hydrocarbon molecules. After emulsification has a strong adhesive ability, after spraying the surface can quickly form a cemented film, the soil particles into the ideal aggregate, thereby increasing the ground temperature, inhibit soil moisture evaporation, crop growth period not only in advance, and the average
