【摘要】 <正> 水稻主要病虫害综合防治技术的研究是全国“六五”期间攻关项目。在1980年国家提出“病虫综合防治”设想和各参加单位原有工作基础上,经过充分酝酿和准备,通过三年来(1983—1985)的协作攻关,成效比较显著。开发出十项关键性综防技术,基本上形成了我国五大稻区水稻病虫综合防治技术体系,提出了各稻区区域性综防要点,通过这项工作的开展和影响,改变了“单一病虫”的防治局面,使水稻病虫防治跨入一个新的阶段——即有计划地开展综合防治的历史阶段。更多还原

【Abstract】 The integrated pest control (IPC) strategy in five main rice growing regions namely the plain between the Changjing river and the Huaihu river, the plain of the Taihu lakeside, the Western plain of Sichuan Province, the plain of the Donting lakeside and the Delta plain of Zhujiang river,has been established in recent years. Variety resistant to leaf blight and rice blast was taken as the crucial approach complemented with rational use of pesticide and protection of beneficial insects in the IPC programme. Since the damaged plants could be well compensated through its internal self-regulation, it was proved that the economical threshold of rice leaf folder, striped stem borer, rice thrip and sheath blight could be widened to 2-5 times that of the conventional control index. Adequate fertilization, especially in applying nitrogen fertilizer, akd method of pesticide application were emphasized, The results of IPC in five main rice growing regions were fruitful. Epidmic of leaf blight, rice blast and BPH were well controlled, 59% pesticide and 30% labour force were saved, the residue of organic chlorinated pesticide in the rice hull and soil of paddy field was decreased to an acceptable level and the prosperity of beneficat animals as well as aqoatic organisms recovered to a prospective status. Both farmers and community got economical,ecological and social benefits from the IPC programme which brought the principles of the strategy for its integral, egionul and critical characters to reality.更多还原
