大豆田使用氟乐灵在播前进行土壤处理,能控制早期杂草,使大豆出苗后在杂草较少的环境中正常生长。但氟乐灵对阔叶杂草的防效较差。为了进一步提高对大豆田杂草的防效,我们引进赛克并与氟乐灵混配进行了试验。一、材料与方法 1.试验田概况:试验区设在新曹农场农科站1号田,面积0.54亩。大豆品种为灌豆1号,前茬大麦。沙壤土,有机质含量1.84％,pH7.5,播种时土壤含水量20.01％。大豆人工开
Soybean fields are treated with trifluralin prior to sowing soils can control early weeds and allow normal growth of the weeds in less weedy environments after emergence. However, trifluralin against broad-leaved weeds less effective. In order to further improve the control effect on weed in soybean field, we introduced Saik and tested it with trifluralin. I.
