摘要
针对以波斯婆婆纳为主的旱地麦田杂草群落，用１１个除草方案进行了小区化除试验，并对试验结果进行了层次分析基础上的模糊综合评价。结果表明，１１个方案的优劣顺序为使它隆２０％乳剂（２５ｍｌ／６６７ｍ２）＋２甲４氯２０％水剂（１００ｍｌ／６６７ｍ２）、２甲４氯２０％水剂（２５０ｍｌ／６６７ｍ２）、使它隆（氟草烟）２０％乳剂（６０ｍｌ／６６７ｍ２）、绿麦隆２５％可湿性粉剂（２５０ｇ／６６７ｍ２）、绿麦隆２５％可湿性粉剂（１７２ｇ／６６７ｍ２）＋杀草丹５０％乳剂（１６０ｍｌ／６６７ｍ２）、双磺隆２０％可湿性粉剂（５ｇ／６６７ｍ２）、绿磺隆２５％可湿性粉剂（５ｇ／６６７ｍ２）、甲磺隆１０％可湿性粉剂（８ｇ／６６７ｍ２）、麦草宁２０％可湿性粉剂（４５ｇ／６６７ｍ２）、苯磺隆１０％可湿性粉剂（１０ｇ／６６７ｍ２）、甲磺隆１０％可湿性粉剂（６２ｇ／６６７ｍ２）＋２甲４氯２０％水剂（１７６ｍｌ／６６７ｍ２）。
Chemical control tests on weed communities whose dominate species was Veronica persica in wheat fields were carried out.Herbicide efficacy,herbicide price,damage to crop and the spectrum controlling weeds were taken as indices,their weights were obtained based on the analytic hierarchy process(AHP),fuzzy integrated evalution was applied to evaluate the performances of these designs,the results showed that the designs from the best to the worst were Starane 20% (375ml/ha)+MCPA 20%(1500ml/ha)、MCPA 20%(3750m/ha) 、Starane 20% (900ml/ha)、chlortoluron 25%(3750g/ha)、chlortoluron 25% (2625g/ha)+benthiocarb 50%(2400ml/ha)、chlorsulfuron+metsulfuron 20%(75g/ha)、chlorsulfuron 25%(75g/ha)、metsulfuron-methyl 10%(120g/ha)、Maicaolin 20% (67.5g/ha)、tribenuron-methyl 10%(150g/ha)、metsulfuron-methyl 10%(93g/ha)+MCPA 20%(2640ml/ha)respectively.
