| 摘 要： | 东北稻区自生杂草稻在目前常用的稻田除草剂常规剂量处理下株防效为0,种子埋深10 cm以下才能控制其萌发出土,灌水深度10 cm对种子发芽没有明显的抑制作用.在秋季灌水条件下越冬的种子冻死率为100％,而在干燥态土壤中多数种子可安全越冬.

| Abstract: | The individual weeding rate of autogeny weedy rice in Northeast China under herbicide treatment at conventional dose is O. The seeds can only be controlled for germination when the weedy rice seeds are deeply buried 10 cm below, and 10 em of irrigating water has no obvious effect on controlling of the weedy rice seeds germination. Cold mortality of the overwintering weedy rice seeds under the condition with autumn irrigation is 100%, while most of the seeds in the dry soil can live through the winter safely. |
