摘  要：
【目的】研究煤粉对于控制粪肥施用后农田径流磷流失的作用,为研发适用于小农户的农业面源污染控制技术提供科学依据和技术参考。【方法】在自然降雨条件下,采用径流试验装置,设置不施肥、单施猪粪、猪粪添加煤粉3个处理,对种植期内地表径流的体积、不同形态磷的质量浓度及流失量进行检测,分析猪粪添加煤粉施用对地表径流磷流失及植株生长的影响。【结果】与单施猪粪相比,添加煤粉可以减少地表径流的产生,显著降低不同形态磷的质量浓度和流失负荷。总磷(TP)、水溶性总磷(TDP)、颗粒态磷(PP)、水溶性无机磷(DIP)和水溶性有机磷(DOP)质量浓度分别降低22.54%、16.84%、27.84%、20.94%和5.10%,流失负荷减少26.6%、19.6%、32.0%、23.2%和14.5%。添加煤粉对前2茬小白菜生长不利,但从第3茬开始出现显著的促进作用。【结论】添加煤粉可以有效降低猪粪施用后引起的农田径流磷流失风险,但可能存在一段对作物生长不利的时期。

摘  要：
[Purpose]To gain knowledge of the effect of coal powder application on controlling phosphorus loss through runoff caused by manure application, and to provide scientific basis and technical reference for the research and development of technology applicable to small farmers to control agricultural non-point source pollution.[Method]Farmland runoff simulation experiment was carried out under natural rainfall regime and three treatments were designed, that was non-fertilizer, pig manure only, pig manure plus pulverized coal. During the culture, the volume, concentrations and loss load of phosphorus in various forms of runoff were tested to study effects of pig manure application mixed with pulverized coal on phosphorus loss through runoff and the growth of plants.[Result]Compared with pig manure application only, pig manure application mixed with pulverized coal could reduce the amount of runoff produced during the rainfall, and significantly lowered the concentration and loss load of different phosphorus species. The concentrations of total phosphorus(TP), total dissolved phosphorus(TDP), particle phosphorus(PP), dissolved inorganic phosphorus(DIP), dissolved organic phosphorus(DOP) in surface runoff were reduced by 22.54%, 16.84%, 27.84%, 22.54% and5.10%, while loss load reduced by 26.6%, 19.6%, 32.0%, 23.2% and 14.5%. The addition of pulverized coal had a negative effect on the growth of pakchoi of the first two crops, but a better promotion effect was observed starting from the third crops.[ Conclusion] The addition of pulverized coal could effectively reduce the risk of phosphorus loss through runoff caused by pig manure application in farmland,which yet may produce a bad effect on the plant growth during a time.
