摘要
研究选择生长速度快、具有一定经济价值的甘薯替代控制紫茎泽兰（Eupatorium adenophorum Spreng）,通过在湖北和四川的田间试验,观察甘薯替代紫茎泽兰的防治效果,以及对紫茎泽兰生长的影响。试验结果表明,无论是淀粉型还是叶菜型甘薯均能有效控制紫茎泽兰,其防控效果为98%-100%,并且能极显著地降低紫茎泽兰对氮、磷、钾和水分的消耗,保持田间水肥条件,保障了甘薯的增产和增收。
The replacement control of crofton weed（Eupatorium adenophorum Spreng） was researched by using sweet potato which growed quickly with certain economic value. The control effect of alternative and its influence to the crofton weed growth were observed in Hubei and Sichuan field experiments. The results revealed that both starch-type and leaf-vegetable variety sweet potato can significantly inhibit the growth of crofton weed in the infected field with control effect of 98%-100%.And the two variety sweet potatoes can significantly reduce the consumption of nitrogen,phosphorus, potassium and water by crofton weed, to keep watering and fertilization of the field, which can protect sweet potato production and income.
