摘要
我国是水土流失比较严重的国家之一。目前,治理田间水土流失主要有工程措施、生物措施、农业措施等,但都存在或投资大、或周期长、或见效慢等不足。本文应用具有防治水土流失作用的高分子聚合物--聚丙烯酰胺的最优剂型,进行室内试验研究,提出了聚丙烯酰胺防治土壤侵蚀的适宜用量,为化学措施防治水土流失研究奠定了基础,为田间施用聚丙烯酰胺防治土壤侵蚀提供依据和指导,具有重要意义。
China is one of the more serious soil erosion countries. At present, the soil erosion control in fields mainly includes engineering, biological and agricultural measures, but they have the disadvantages of large investment, or a long cycle, or taking effect slow. This paper introduces the experimental research optimal dosage of polyacrylamide possessing to prevent soil erosion and put forward the appropriate amount of soil erosion prevention and control, and has laid a foundation for chemical measures to prevent soil erosion research, and provides the basis for the field application of polyacrylamide reference.
