We can increase the adsorbed and fixed function of NH_4~+ through put SARs in soil, and decrease the eluviation lose of nitrogen。
8、在土壤中加入高吸水性树脂可以增加土壤对铵离子的吸持作用,减少氮素的淋失。
参考来源 - 高吸水性树脂与铵离子间的相互作用研究This study takes "source control" as fundamental point,adopt laboratory simulating and field experiments,research the effects of PAM application on the nitrogen's move and eluviation in the Three Gorges purple sloping field.
本研究以“源头控制”为基本出发点,采用室内模拟试验和田间小区试验等相结合的研究手段,系统的研究PAM对三峡库区紫色土坡地氮素迁移淋失的影响。
But the sewage sludge includes some heavy metal, which is harmful to the environment and the humanity. It is one of hindrance factors that whether the heavy metal will pollute the underground-water or not through long-term eluviation.
但是污泥中含有一定量对环境和人类健康有害的重金属等有害物质,配施到石灰岩质土中,经过长期的淋溶作用是否会对地下水产生影响值得深入研究。
