液态地膜是由中国农科院土肥研究所、北京燕山石化公司研究院等五家科研单位共同研制的新产品,该产品为液体乳剂,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,使作物生育期提前,而且平均增产幅度在20％以上。 液态地膜与普通地膜相比,优点有
Liquid membrane is a new product jointly developed by five research institutes including Soil and Fertilizer Institute of Chinese Academy of Agricultural Sciences and Beijing Yanshan Petrochemical Company Research Institute. The product is a liquid emulsion consisting of long-chain hydrocarbon-based molecules with strong adhesion after emulsification , After spraying the surface can quickly form a cemented film, the soil particles together into an ideal aggregate, thereby increasing the ground temperature, inhibit soil moisture evaporation, crop growth period ahead of schedule, and the average yield increase of more than 20%. Liquid film compared with ordinary film, the advantages are
