沈抚污水灌区石油烃对土壤及水稻的影响

Effect of Petroleum Groups on Soil and Rice in the Shen-Fu Irrigation Region

本文通过对沈抚灌区土壤及水稻的采样分析,同时结合水稻盆栽试验,分析测定了污灌区土壤中石油烃的残留及其对水稻生长的影响。结果表明土壤中石油烃含量同污灌年限、物理性粘粒含量及土壤质地等有着一定的相关关系,土壤中石油烃含量越高对水稻生长发育的影响越大。

On the basis of test and analysis, the article deals with the relationship between the petroleum groups and the plant growth. The results showed that petroleum groups content in soil was releted to irrigation time, clay content and soil quality. The higher content of petroleum groups was, the heavier the effect was.
