天水地区小麦病虫害综合防治技术研究

The Integrated Controlling Techniques ofWheat Diseases and Pests in Tianshui Areaof Gansu Province

天水地区小麦病虫害以条锈病、白粉病和麦蚜为主。通过1986～1990年的研究,提出了一套适于该地区推广的以农业措施为基础,化学防治为重点,发挥品种本身抗性,保护、利用天敌的策略和配套的技术措施。在2万亩示范区实施5年,累计挽回小麦2766t,折合182.5万元,还有力地带动了天水市小麦病虫害综防工作,社会效益显著。

Wheat stripe rust, wheat powdery mildew and wheat aphids are the main pests of wheat in Tianshui area. On the basis of research in 1986-1990, a series of strategies and technical methods applicable to that area wer e recommended. The strategies are that the author should lay stress on agro-techniques, give priority to chemical control, bring the role of resistance of wheat cultivars themselves into full play, and protect and utilize natural enemies. The above mentioned strategies and technical methods have been used on 20 thousand mu in the past five years, and achieved very good results. It totally retrieved a loss of 2766 tons of grain, which can be converted into 1 825 000 yuan.
