摘要
在日光温室、塑料大棚和基本农田条件下,应用48％氟乐灵(Trifluralin)与48％地乐胺 (Butralim)对紫花苜蓿(Medicago sative)进行播前土壤处理与播后地表封闭防治苗期田间杂草试验,结果表明:48％氟乐灵播前7d进行土壤处理,紫花苜蓿种子发芽出苗基本上不产生药害,并能有效控制苗期杂草,防治效果在95％以上;48％地乐胺播后24h内进行地表封闭,可以控制紫花苜蓿苗期田间杂草, 但是要严格掌握用药量。48％氟乐灵+48％地乐胺对紫花苜蓿进行播前土壤处理和播后地表封闭,控制苗期田间杂草效果较好。
In greenhouses, big plastic sheds and basic farmland, 48% Trifluralin and 48% Butralim are used to dispose the soil before sowing the Alfalfa (Medicago sative). They are also be used to seal up the soil surface in order to prevent and cure the weed during the period of the seedling. The result of the experiment indicates that there is almost no Herbicide harm with 48% the Trifluralin disposing the soil 7 days before sowing, and it can control the weed in the farmland effectively. The prevention and cure result is over 95%. Sealing up the surface of the soil with the 48% the Butralim 24 hours after sowing can control the weed in the farmland during the seedling period, but controlling the quantity of the Herbicide strictly is very important. The effect is the better to control the weed in the farmland by disposing the soil and sealing up the soil surface with 48% both Trifluralin and 48% Butralim .
