| 摘 要： | 休眠是杂草种子萌发的内在因素,研究杂草发生,首先要研究种子的休眠,通过26种主要农田杂草种子休眠萌发的试验,提出了以碎米荠为代表的越夏休眠;以稗草、藜为代表的越冬休眠;以看麦娘为代表的越夏、越冬休眠;以马唐、绿狗尾为代表的越冬、越夏休眠。同时还研究了环境条件对休眠萌发的影响。猪殃殃等早生杂草在含水量15%左右土壤的旱田内,易渡过休眠,而在浸水情况下难于渡过休眠,反之稗草、硬草等湿(水)生杂草在浸水的情况下,易解除休眠。看麦娘、稗草、异型莎草在20～30℃时易解除休眠,唯独小藜是在低温下解除休眠。

| Abstract: | Dormancy is an internal factor which effects germination of weed seeds.In order to understand their germination.We have to study the dormancy of weed seeds.In 1975~1978,we collected seeds of different species of weeds a year ahead.They were placed in nylon mesh bags and buried at 12~15cm.under ground,then they were uncovered from soil for testing the percentage of germination once a month. |
