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 m2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。
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 herbicide 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 m2, 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 herbicide in lawn and economize manpower and resources (The weigh ratio of effective composition of two herbicide is 1:1).
