【摘要】 本试验研究了草坪宁51号和草坪宁71对狗牙根草坪上杂草的防除效果,结果表明,在草坪杂草1～4叶期,用草坪宁51号和草坪宁71混合进行防除,对杂草的防除效果比单独使用时的防除效果好。其混合用量 (按两种药剂的有效成分的重量1:1的比例混合)为4．5 ml/10 m~2时,对杂草的防除效果较好。混合使用化学除草剂,可以节省用药量,降低除草剂在草坪上的残留量,并且节省了人力和物力。更多还原

【Abstract】 This experiment research is that when they were used in the Bermuda grass turf the Caopingning-51 herbicide and Caopingning-71 herbicide controlled the effect of weed which the Caopingning-51 herbicide and Caopingning-71 her- bicide were used by way of solitude and combination.The result indicate that when the weed were in one leaf to four leaf, the effect which the Caopingning-51 herbicide and Caopingning-71 herbicide were used by way of combination was better than solitude when the weight of combination was 4.5ml/10 m~2,the effect which they controlled weed was much better.That the chemical herbici de was used by way of combination may cut down the weight of herbicide,reduce remaining of the her- bicide in lawn and economize manpower and resources(The weigh ratio of effective composition of two herbicide is 1:1).更多还原
