玉米田杂草种类多、密度大,大部分田块是禾本科杂草和阔叶杂草混生,如果玉米苗期防除杂草不及时,将对产量造成很大影响。播后苗前进行土壤封闭是玉米田化学除草一种有效手段。42%异丙草胺.莠去津悬乳剂通过混用提高防效,降低莠去津用量,避免其对后茬作物的影响。2004年我们进行了42%异丙草胺.莠去津悬乳剂在播后苗前土壤处理防除玉米田杂草的药效试验,明确了该药对春玉米田杂草的除草效果及对玉米生长的影响。
Cornfield weeds species, density, most of the plots are grassy weeds and broadleaf weed mixed, if the corn seedling weed control is not timely, will have a significant impact on the yield. Soil seedling before sowing is an effective means of chemical weeding in corn fields. 42% Propisalazine Atrazine Suspension mixed to improve the control effect, reduce the amount of atrazine, to avoid its impact on the following crop. In 2004 we conducted a 42% isopropcosamide.Atrazine Suspension in the soil after sowing seedlings in front of the control of weeds in cornfield efficacy test, the drug clear weed on spring corn weeds and corn The impact of growth.
