摘要
本文通过试验及简捷的计算,求得扁秆簏草种群的内禀增长率,从而进一步判断扁秆麓草“疯长”的关键时刻,为有效地控制此种恶性杂草的危害提出了可行措施。
The intrinsic rate of natural increase of Scrirpus planiculmis Fr. Schmidt is got through the rese and simple calculation. Therefore, the cause and cruciai time of Us excessive population could be predicted. It is posstble to work out measures and to control the weeds effective
