摘    要:90年代 ,新型PAM产品 (具有很高分子量的阴离子型PAM )和改进的应用技术 (低用量配合灌溉水 )使得PAM在农业上的使用成本大大减少 ,而农用效益大大提高 ,土壤调理剂PAM的农用重新受到重视。目前美国西部已将PAM的农用作为一项农田水土保持新技术而得到越来越广泛的应用。土壤调理剂PAM曾于 80年代后期介绍到我国 ,但是由于成本高等其它问题而未能在农业上推开 ,目前新型PAM的农用研究也在我国引起重视。国外大量研究和国内有关研究表明 ,PAM的农用效益体现在水土保持、灌溉效率、农业生产、环境、经济等方面。土壤调理剂PAM用于农田水土保持、防止水土流失前景看好

关 键 词:土壤调理剂   PAM   水土保持

Abstract:In the 1990’s a great interest to PAMs’ agricultural use was renewed to arouse with the development of the advanced PAM(very high molecular weight anionic PAMs) and the new application strategies(at very low rate via irrigation water),which makes it possible to reduce the cost and increase the benefits for practical agricultural use. Nowadays, the use of PAM was issued a western states interim conservation practice in the USA. In the late of 1980’s PAM was introduced into China, however, has not been adopted for agricultural use because of high cost and some other problems. Research on the new PAM used in agriculture is also being given reconsideration. Studies at home and abroad showed that the use of PAM could provide soil and water conservation,ingation, efficiency, crop production, and environmental and economical benefits. Use of soil conditioner PAM shows promise in protecting soil and water from erosion.
