摘  要:
[目的]确定延长波尔多液施用间隔时间的可行性,为在实际生产管理中合理施用该药剂提供参考。[方法]2012、2013年分别间隔14、21和28 d施用波尔多液防治苹果褐斑病,评价其对苹果褐斑病的防治效果。[结果]当施用波尔多液间隔期为28 d时,减少施药次数1~2次,仍能有效防治苹果褐斑病。[结论]通过试验延长了波尔多液的施药间隔期并减少了使用次数,节省了成本,降低了污染。

摘  要:
[Objective] The feasibility of delaying the interval of spraying Bordeaux mixture was understand to provide reference for application of the agent.[Method]In the year 2012 and 2013,the Bordeaux mixture was spraying against apple leaf brown spot and three different intervals( 14 d,21 d and 28 d) were used. The control efficiency of Bordeaux mixture against apple leaf brown spot was evaluated.[Result]Bordeaux mixture still took good control efficiency when the interval extended to 28 d,and the applying times was decreased by 1-2 times. [Conclusion]Extending the internals of spraying Bordeaux mixture can reduce the spraying times,save the cost,and reduce the pollution.
