中文摘要 | 本試驗主要為探討施藥技術及栽培管理方式對水稻水象鼻蟲(Lissorhoptrus oryzophilus Kuschel)之防治效果。結果顯示,以插秧機附掛深層側條施肥機施藥防治水象鼻蟲效果最為顯著。省工防治試驗結果顯示,以依芬寧藥劑「集中式施藥」(周圍施藥、投入施藥、滴定施藥)可以有效防治水稻水象鼻蟲,比一般水面施藥更省勞力。插秧期之影響試驗顯示,第一期作晚植可以避免越冬成蟲侵入為害產卵。而水稻插秧後是30天起排水曬田如超過10天幼蟲族群明顯下降,稻穀產量比未處理增加9.3-15%。 |
英文摘要 | Field experiments were conducted at the Taoyuan District Agricultural Improvement Station, Hsinwu during the two crop seasons of 1994 to determine the effects of inseticide application and cultural methods on the control of the rice water weevil (RWW) Lissorhoptrus oryzophilus Kuschel. Slide dressing application with fertilizers and the concentric application (peripheral application, throwing application and dripping application) of ethofenprox in the peripheral zone of a paddy field was effective in controlling of the RWW and resulted in an increase of grain yield. Delayed planting is also effective to avoid the peak of adult oviposition after hibernation. Results was showed that the population and pupa reduced apparently while the duration of field drainage for more than 10 days. As a result, the yield increase from drainage plots was 9.3 to 15% over the control. |
