| 摘 要： | 在结缕草萌动前对结缕草草地进行火烧处理,研究生长季内不同月份火烧对结缕草草地杂草的控制效果。结果表明:整个生长季内火烧对结缕草草地杂草株数、植物量(地上,干重)均有较好的防控效果,平均防控效果分别为23.97%、39.90%;株数防控效果最好为5月份,为40.95%,植物量防控效果最好为10月份,为65.74%;火烧对结缕草草地杂草的防控效果在春季主要表现在防控杂草的数量(株数),在秋季主要表现在防控杂草的重量(地上植物量)。 |

| Abstract: | The effects of fire before regreening on the control of weeds in Zoysia japonica grassland were studied and the results showed that the average control rates in terms of plant number and aboveground phytomass in the growing season were 23.97% and 39.90% respectively.The control rate for weeds number reached the highest in May(40.95%),and it was in Octorber(65.74%) for aboveground phytomass.This suggested that the features of weeds control by fire were lower weeds density in spring and lower phytomass in autumn. |
