摘要
以玉米为指示植物,在设置不同的土壤湿度、添加不同的肥料和采用不同的接菌方式等条件下,通过作物的形态和生理指标系统地评价了(X、Y1、W2)3种微生物降解土壤中异噁草酮的效果。结果表明,当土壤湿度为田间持水量50%时,3个菌株对异噁草酮的降解效果均最好;在处理90d内,随着降解时间的延长,加入降解菌的处理对土壤的修复效果明显好于对照;添加肥料能够显著提高降解菌对土壤的修复作用,其中添加无机肥的降解效果明显好于有机肥。
The experiment evaluated the, effects of clomazone degrading bacteria named X, Y1 and W2 under different soil moistures, different fertilizer applications and different inoculation methods by corn＇s morphological and physiological indexes. The results showed that the degradation effect of three bacteria under 50% of water field capacity （WFC） in soil was the best. The soil bioremediation effects of treatments with bacteria added were evidently better than that of the blank control within 90 days. Fertilizer could enhance the bioremediation ability of degrading bacteria evidently, and the degradation effect of applying inorganic fertilizer was better than that of applying organic fertilizer.
