中文摘要: |
检测地下水中无机物和嘧磺隆含量,并进行嘧磺隆对蔬菜毒性效应的盆栽试验。结果表明:地下水嘧磺隆污染对大白菜和莴苣生物学性状有明显影响,大白菜叶片变黄,株高与幅宽两项指标均小于对照。莴苣新叶皱缩、扭曲,失绿变黄,老叶枯黄下披,植株生长迟缓,受害严重者死亡。污染区井水处理的莴苣株高、根长、茎粗、叶片数、叶片总面积均比对照降低;对大白菜、莴苣叶绿素及电导率的测定结果表明,污染区井水处理会使其叶绿素含量下降,电导率增大;污染区地下水中的嘧磺隆明显降低了大白菜和莴苣的产量,方差分析差异显著或极显著。 |
英文摘要: |
Pot experiments were conducted to investigate toxicity effects of sulfometuron methyl on vegetables on analyzing inorganic matter and sulfometuron methyl contents in groundwater.It provided basis for pollution area to prevent contamination in agriculture production.Research results showed that vegetables were damaged at pollution area by sulfometuron methyl.That groundwater polluted by sulfometuron methyl had obvious effects on biological properties of Chinese cabbage and lettuce.The leaves of Chinese cabbage became yellow,and plant height and breadth were both lower than that of control treatments.The new leaf of lettuce appeared toxicity symptom such as crimple,distort and losing green becoming yellow,and the old leaf scorched.The lettuces grew sluggishly,and some plants that contaminated seriously died.The plant height,root length,the diameter of stalk,number of leaf blade and total acreage of lettuce that treated by polluted groundwater were all lower than that of control treatment.The analyzed results showed that chlorophyll contents decreased and specific conductance increased when Chinese cabbage and lettuce were treated by polluted groundwater,and biological yields decreased.Variance analysis expressed significant difference or very significant difference. |
