摘要
试验采用40%扑·乙EC为土壤处理剂,剂量为3 750 mL/hm2,分4个时期喷施,以探讨除草剂喷施的最佳时期。试验结果表明,马铃薯播种后14～21 d喷施除草剂,对杂草的防除效果最好;苗前无论何时喷施40%扑·乙EC,对马铃薯均安全,植株生长发育正常。
In order to study the optimal period to spray,acetochlor ＋ prometryn 40% EC was used as a soil treatment with a dosage of 3750 mL/hm^2,and sprayed in four different periods.The test results showed that the control effects on weeds were the best when sprayed acetochlor ＋ prometryn 40% EC during the 14th-21th days after sowing.The herbicide was safe to potato and potato plant growth whenever it was sprayed before seedling.
