Abstract
The effects of varietal type and crop season on the performance of some granular herbicides in transplanted rice evaluated at the Chiayi Agricultural Experiment Station, Chiayi, Taiwan, in the first and second crops of 1970 are reportd.
本文係報告嘉義農業試驗分所與國際稻米研究所合作，於民國59年第1期作及第2期作與辦水稻品種與期作對若干水田粒狀除草劑藥效之影響試驗所得結果。鴨舌草與球花蒿草爲試驗田之主要雜草，惟水秤之密度極低。日本型品種嘉農242號試區之雜草數目較印度型品種臺中在來1號者爲多，而第2期作之雜草亦多於第1期作。供試之粒狀除草劑均具良好之治草效果，除草劑冶草效果之品種間差異在生育初期並不明顯，惟在幼穗分化期則可看出明顯差異。即同一除草劑在嘉農242號試區之治草效果稍劣於臺中在來1號。除草劑之治草效果受期作之影響甚微。
