摘　　要：为明确不同除草措施对辣椒地杂草防除效果,采用田间小区试验方法,研究单独施用除草剂、地膜覆盖、除草剂+地膜覆盖不同除草措施对辣椒地杂草防除效果。结果表明,单用除草剂960 g/L精异丙甲草胺乳油、330 g/L二甲戊灵乳油对辣椒地杂草30 d群体株防效分别为68.75%、65.07%,60 d杂草群体株防效、鲜重防效分别为76.50%、82.88%,82.99%、87.35%。白膜覆盖、黑膜覆盖、白膜覆盖+960 g/L精异丙甲草胺乳油、白膜覆盖+330 g/L二甲戊灵乳油、黑膜覆盖+960 g/L精异丙甲草胺乳油、黑膜覆盖+330 g/L二甲戊灵乳油对辣椒地杂草30 d群体株防效均达97.00%以上,60 d群体株防效均达96.00%以上,鲜重防效除白膜覆盖+960 g/L精异丙甲草胺乳油处理外,均达93.00%以上。综合试验结果表明,地膜覆盖、除草剂+地膜覆盖均能较好地防除辣椒地杂草,实际生产应用中为减少农药使用可直接覆盖地膜防除辣椒地杂草。The efficacy of different control measures:herbicidesused individually,mulch covering and the combination of herbicide with plastic film mulching was determined in pepper fields. Efficacy based on plant mortality of 960 g/L(S)-Metolachlor EC and 330 g/L Pendimethalin EC was 69% and 65% at 30 days after treatment(DAT) and 76% and 83% at 60 DAT,respectively. At 60 DAT control achieved with these herbicides was 83% and 87%,respectively,based on fresh weight determinations. The efficacy of other measures(combination of individual herbicides and white or plastic film) was above 97% at 30 d,and greater than 96% at 60 d. Based on the obtained results,both plastic film mulching and herbicide + film mulching affectively control weeds in pepper. To decrease the dependence on herbicides,theuse plastic film mulching is suggested for controlling weeds in pepper fileds.
