| 摘 要： | 由于马铃薯从播种到出苗时间长,本试验对何时使用苗前除草剂进行研究。结果表明：用90%乙草胺1950ml/hm^2＋70%嗪草酮450g/hm^2,苗前无论何时喷施对马铃薯田均安全;对产量影响不大,未达到显著水平;除草效果以播种后15～20d喷施除草剂,除草效果最好。

| Abstract: | As the potato requires a long time from planting to germination,the test for when to use preemergence herbicides were conducted.The results show that the potato fields can be sprayed with 90% acetochlor 1950 ml/ha and 70% metribuzin 450 g/ha in any time before emergence.But the effect on yield is little,and is not reach significant level.The effect of spraying herbicide in 15-20 days after sowing is best. |
