玉米除草剂对10种药用植物的药害研究

将有效成分为55％的丙莠滴丁酯悬乳剂玉米除草剂稀释成浓度为0．55％、0．27％和0．18％水溶液,分别喷施于玉竹、山兰、槭叶草、威灵仙、刺五加、金钱草、毛百合、北五味子、暴马丁香和穿龙薯蓣等10种药用植物,结果表明山兰和玉竹对3种不同浓度除草剂均无药害反应发生,可以与玉米进行粮药复合种植。

Phytotoxicity of Corn Herbicide on Ten Medicinal Plants

A 5 5 % propisochlor-atrazine-2 ,4-D butylate suspoemulson,the commonly used herbicide for corn crops,was diluted with water into solutions with herbicide concentrations of 0.5 5 %,0.2 7 % and 0.1 8% and sprayed on 1 0medicinal plants including Poly gonatum odoratum （Mill.） Druce var.,Oreorchis patens （ Lindl.） Lindl.,Mukdenia rossii （Oliv.）Koidz.,Clematis chinensis Osbeck,Acanthopanax senticosus,Lysimachia christinac Hance,Lilium dauricum,Schisandra chinensis （Turcz.）Baill.Syringa reticulate.,Dioscorea nip ponica Makino.Possible phytotoxicity on the plants were examined.It appeared that P .odoratum and O .patens were notsignificantly affected by the sprays,and therefore,could be safely co-planted with the corns on the fields treatedwith the herbicide for weed control.
