| 摘 要： | 通过盆栽试验探讨了种植皇竹草（Pennisetum hydridum）对阿特拉津污染土壤的修复效果,阿特拉津对皇竹草生长的影响,以及皇竹草对土壤微生物数量的影响,以期为阿特拉津污染土壤的植物修复提供参考。结果表明：在≤200 mg.kg-1质量分数范围以内,种植皇竹草对土壤阿特拉津的初期降解效率比对照明显提高,最大提高了29.64%,达到显著或极显著差异;阿特拉津质量分数在≤200 mg.kg-1范围内对皇竹草株高没有影响,≤50 mg.kg-1质量分数范围内对生物量没有影响,根冠比变化不明显;随阿特拉津质量分数的增加皇竹草根际和非根际土壤中的细菌、真菌、放线菌数量均呈先增加后减少的趋势,在质量分数为100 mg.kg-1时达到最大,根际土壤中细菌和放线菌数量明显高于非根际土壤,真菌数量在根际与非根际土壤中变化不明显。说明种植皇竹草有助于阿特拉津降解效率的提高,且与种植皇竹草后改变了土壤微生物数量及皇竹草的生长状况有关。

| Abstract: | Pot experiments were conducted in order to understand effects of atrazine on growth properties,soil microbial quantities of Pennisetum hydridum and degradation efficiency of atrazine with Pennisetum hydridum.The results indicated that degradation efficiency of atrazine increased significantly under planting Pennisetum hydridum with soil atrazine concentration <200 mg.kg-1 compared with the control.The maximum degradation efficiency reached to 29.64%.Height of Pennisetum hydridum with atrazine concentration ... |
