| 中文摘要: |
| 主要从取样方法、取样时间和种类鉴定等方面对土壤种子库研究方法进行综述,重点介绍了种子萌发法,并且提出了要采取长期定位观测的方法对土壤种子库的长期完整动态进行较系统的研究,而且最好在种子库长期的定位研究中搞清楚研究区内植物种的物种特性并且建立一个幼苗标本库,以增加土壤种子库研究的准确性。 |
| 英文摘要: |
| Soil seed bank includes all live seeds existed both in litter and in soil,which is simply classified into transient soil seed bank with seeds germinated within a year of initial dispersal,and persistent soil seed bank with seeds remained in soil more than one year.The soil seed bank,as the potential for regeneration,plays an important role in the natural restoration of vegetation.This paper reviewed its research methods,including sampling methods,sampling time and identification of seedling.It suggests that long-term anchor observation is adopted for the dynamics of soil seed bank and seedling specimen bank should be founded to identify seedling correctly. |
