近年来,随着种植业结构的不断调整,河北省邯郸市的棉麦两熟面积不断扩大,其中麦套棉面积每年已达12.5万公顷,占全市植棉总面积的60％。种植结构的变化致使棉田生态结构发生改变,形成棉花病虫害发生的新特点。我们针对本市棉花病虫害发生情况推广了麦套棉病虫害防治配套技术,1992～1995年累计应用55.2万公顷,约可节约防治成本1.82亿元,取得了显著的经济、社会和生态效益。
In recent years, with the continuous adjustment of planting structure, the area of cotton and wheat double cropping in Handan City, Hebei Province, has been continuously expanded. The area of wheat-cotton area has reached 125,000 hectares each year, accounting for 60% of the total area of cotton planting in the whole city. Changes in planting structure led to changes in the ecological structure of cotton fields, the formation of new features of cotton pests and diseases. In response to the occurrence of cotton pests and diseases in this Municipality, we have popularized the supporting technologies for the prevention and control of wheat and cotton pests. From 1992 to 1995, a total of 552,000 hectares were used, which saved about 182 million yuan of prevention and control costs and achieved remarkable economic, social and ecological benefits.
