| 摘 要： | 林业苗圃杂草种群结构的研究结果表明:苗圃地的杂草种群结构受环境条件的影响,不同的覆盖物、不同的时期杂草种群的结构有所差异;苗圃杂草种群的形成有一定的规律,遵循S型曲线的变化规律;杂草种群个体数量的高发生期在10 d左右,一般在6月中旬大量发生;播下林木种子后,立即施用除草剂,能够有效地控制杂草种群,缩短杂草的大量发生期限。

| Abstract: | The weed population structure was measured in forest nursery.The results showed that population structure was affect by environmental conditions.The weed population structure varied among populations with different coverage at different time.The size of weed population changed following S curves.The peak number of individuals in weed population occurred at middle of June for about 10 days.To control weeds effectively and shorten the term weeds bursting,the herbicide should be used immediately after seeds of forest-tree were sown. |
