摘 要:灭鼠时间,投饵量和投饵位置是决定灭鼠效果的关键因素。本文采用正交旋转组合设计试验对此作了较详细的研究,并据此把灭鼠时间、投饵量、投饵位置有机地结合起来,提出了“春季灭鼠、分片定量、定向投饵”的规范化配套技术。经几年多点100万亩以上的大而积示范证明,此项技术具有防治成本低、直接灭鼠效果高等优点。The controling time,quantity of baits deposited and the technology of baits deposition were the key factors to decide the efficiency of rats control.The problems above were studied by means of orthogonal reverlution design test.A specification technology and their complain- ing means of rats chemical control were put forward,e.g.optimal time was spring,baits quantity varied with fields and baits putting location. This set of technology was applied more than one million mu from a few counties in past years showed that it needed less cost but more ef- ficient.
