在人工降雨条件下,应用土壤改良剂和除草剂的不同组合处理,对美国中西部典型土壤类型——迈阿密土壤进行了室内模拟侵蚀试验,以研究土壤改良剂和除草剂的交互作用对土壤侵蚀的影响。结果表明:6种处理中,以土壤改良剂Gypsum和除草剂Atrazine和Metolechlor混合液的组合对降低地表径流,减少土壤流失,增加土壤渗透性能效果最好,其次为土壤改良剂PAM和除草剂混合液的组合,而土壤改良剂Agri-SC和ALES与除草剂混合液的组合处理则对减轻土壤侵蚀没有明显效果。
Under the conditions of artificial rainfall, different simulated soil amendments and herbicides treatments were used to simulate indoor soil erosion of Miami, a typical soil type in the Midwest of the United States to study the effects of soil amendments and herbicides on soil erosion Impact. The results showed that the combination of soil conditioner Gypsum and herbicide Atrazine and Metolechlor had the best effect on reducing surface runoff, soil erosion and soil permeability, followed by soil conditioner PAM and herbicide Liquid combination, and soil amendments Agri-SC and ALES combined with a mixture of herbicides have no significant effect on reducing soil erosion.
