[目的]探索农村公路交通污染对水稻土壤的影响程度。[方法]以距离公路10、50、200 m的盆栽水稻为研究对象,探讨公路交通污染对水稻土壤微生物种群和数量的影响。[结果]拔节期：在0～10 cm的土壤中,距离公路10和50 m的微生物数量明显少于距离公路200 m的。灌浆期：3个点的不同土层中土壤微生物数量明显高于拔节期,且在距离公路50 m的0～10 cm土层中微生物的数量对比拔节期明显上升。成熟期：0～10 cm土层中,相比灌浆期,距离公路10 m的微生物数量有所提升,距离公路50 m的有所下降;10～20 cm土层中,微生物数量比灌浆期有所上升。而在距离公路200 m的各个土层中的微生物数量受交通污染影响不明显。[...

[Objective] The effect of the rural road traffic pollutant on the microbial population in paddy soil was explored.[Method] The potted rice with 10,50 and 200m away from road being taken as experimental material,respectively,the effect of the road traffic pollutant on the microbial population and quantity in paddy soil was researched.[Result] The microbial quantity in the soil level of 0-10 cm,which was 10 and 50 m away from road,was obviously less than that in soil that was 50 m away from road in rice jointing stage.The quantity of microorganism at the different levels of 3 sampling spots in r...
