| 摘 要： | 通过研究多年生黑麦草(Lolium perenne L.)+白三叶(Trifolium repens L.)混播人工草地,探讨了刈割强度与杂草入侵能力间的相互关系。结果表明:入侵杂草的物种数、密度和生物量与刈割强度具有较强的相关关系,其物种数随刈割强度的增加而呈增—减—增的趋势,密度随刈割强度的增加而增加,生物量在轻度刈割、中度刈割时降低,重度刈割时增加。从刈割强度对杂草入侵能力变化的幅度来看,刈割对多年生黑麦草+白三叶人工草地中杂草的入侵影响不大。 |
| 关 键 词： | 人工草地 杂草入侵 刈割强度 |

| Abstract: | The relationship between mowing intensity and weed invasion and the underlying mechanisms in Lolium perenne +Trifolium repens artificial pasture were studied.The results showed that mowing intensity had good correlation with invading species number,individual invaders species number and invading species biomass in different mowing intensity.The trend of invading species number was in increase-decrease-increase trend when the mowing intensity increase.The trend of individual invading species number was in i... |
