稻秆潜蝇综合防治技术研究

INTEGRATED CONTROL TECHNIQUES FOR CHLOROPS ORYZAE

稻秆潜蝇是浙南山区水稻生产的重要害虫。通过推广薄膜育秧、绿肥田除草、选用抗性品种、实行健身栽培、生态控制等─系列综合防治技术，可达到经济有效的防治效果。在水稻整个生长期可减少用药1～2次，稻秆潜蝇穗被害率减轻41.03％，病虫害损失控制在3.6％以内，稻谷增产9.2％，稻田害虫天敌蜘蛛和黑肩绿盲蝽分别增加38.1％和26.3％，获得了明显的生态、经济效益。

Chlorops oryzae is a major pest in rice field in mountain area of South Zhejiang province. Good results can be achieved through the application of a series of integrated control techniques such as growing rice seedlings with plastic mulching, controlling weeds in green manure field, using resistant rice varieties, cultivating strong rice seedlings, and using ecological control methods. Using the integrated control techniques mentioned above, the numbers of chemical sprayings could be reduced one or two times, the incidence of harmed rice spike reduced41.02％ , the yield loss caused by pests was limited within3.6％ , and the yield increased9.2％ . Moreover, the populations of spiders and Cyrtorrhinus lividipennis increased38.1％ and26.3％ respectively. Distinctive ecological and economic benefits were achieved.
