摘　　要：狼尾草(Pennisetum alopecuroides)是新型的园林观赏植物,在我国具有广阔的发展前景。利用化学除草剂防除狼尾草生产与应用中的杂草问题,对减少生产与管理费用意义很大。采用盆栽方法研究了狼尾草对常用的苗前型除草剂的抗药性,以期找出适宜控制狼尾草杂草的安全除草剂与安全用量。结果表明,狼尾草喷施异丙甲草胺后叶片变为紫红色,产生严重药害,草酮在2700mL/hm2用量下或二甲戊乐灵在3500mL/hm2用量下狼尾草的生长仍安全。Pennisetum alopecuroides is a new-style ornamental plant which has a broad foreground for application in china. It has a great significance for reduce the cost of management by using the herbicides to control weed. The tolerance of Pennisetum alopecuroides to common emergence herbicides with potted method was studied in order to find the security herbicides and suitable dosage. The results showed that there will be a serious injury on Pennisetum alopecuroides and the color of leaves became mauve by spraying metolachlor and it is security for Pennisetum alopecuroides growth by spraying the herbicide of 2700 mL/ha oxasiazon 3000 mL/ha pendimethalin.
