摘  要:
通过对森林苗圃中杂草种子在其种子库中存留和田间实际发生情况的调查和统计,揭示了森林苗圃杂草种子库中杂草种子的动态特征,提出了森林苗圃中杂草种子库内种子数量是非常庞大的观点。并着重探讨了各类育苗地上杂草种类和数量的释放规律,发现森林苗圃杂草发生数量变化在76—1381株/m~2·a之间,而种子库中种子数量为3100-7150粒/m~2。最后,从杂草发生角度,将东北森林苗圃中主要育苗地上杂草发生情况进行初步归类,以便为科学地防除杂草提供依据。

摘  要:
The investigation and statistics on weed persistence in seed bank and actual occurrence in forest nursery,reveal the dynamic characteristics of seed in forest nursery weed seed bank and put up a review that the existing quantites of seeds are fairly enormous but their release is very limited. The actual weed quality range from 76—1881 weeds/m~2·a on forest nursery, but the weed seed accounts for 3100—7150 grains/m~2. From view of weed occurrence, the seedling-plots in Northeast forestry nursery are classified,it provides scientific basis for preventing and killing weeds.
