关中灌区小麦主要病虫害综合防治研究

The Integrated Pest Management of Wheat in the Irrigated Area of the Central Shaanxi Province

1986～1990年研究了关中灌区小麦病虫综合防治问题,确定以小麦赤霉病、条锈病、雪霉叶枯病和吸浆虫为主控对象,提出以农业防治为基础,抗病虫品种合理布局为核心,化学防治为关键的综合防治措施,组建了一套适用的综防技术体系,经实施取得了明显的经济、社会、生态效益,并提出了进一步改进和发展的方向。

In the years of 1986-1990, the integrated pest management of wheat in the irragated area of the Central Shaanxi Province was studied, on the basis of which the principal controlling targets including Fusarium head blight (Fusarium graminearium Schw.) , stripe rust (Pucinia striiformis Westend) , Gerlachia leaf blight (Gerlachia nivalis) and red blossom midge (Sitodipiosts mosellana Gehin) was determined. Also, a set of integrated management strategies, monitoring techniques, forecasting with agricultural control as the base, rational distribution of pest resistant cultirors as the kernel, chemical control as the key link were worked out, thus, forming an integrated system of practical management techniques. The notable economic, social and econological benefits were obtained after its application.
