摘要

本試驗以梗稻台農67號及秈稻台中秈10號為供試品種，於1989年2月至1993年5月為期共五年。每年（第一期作）每半個月移植一次，連續進行七次。目的在探討水稻一年一作之最佳種植時期。試驗結果顯示：宜蘭地區一年一作水稻最適當種植期是在四月。就品種而言，梗稻台農67號在每年3至4月移植最佳。秈稻台中秈10號以4月開始移植，可獲較高產量。經分析影響第一期作產量的四項產量構成因素中，梗稻台農67號以“千粒重”及“一穗粒數”二項，對稻穀產量之貢獻量，所佔比值最大，其中“千粒重”一項之相關係數達極顯著水準。秈稻台中秈10號，則以“一穗粒數”對產量之相關係數達顯著水準。如配合穗數，則以“一穗粒數”及“穗數”二項，為決定秈稻產量的最重要因子。

Two rice cultivars, Tainung 67 and Taichung Sen 10 were grown in I-Lan area to clarify the effect of transplanting date on the yield. Each culti-var was transplanted on 7 different date from February to May every year, and whole experiment was conducted 5 years continuously from 1989 to 1993. Results indicated that Tainung 67 transplanted on March or April appeared to have higher 1000-grain weight and number of grain per panicle, which are highly correlated with yield. Taichung Sen 10 transplanted on April had higher number of grain per panicle and of panicle per hill, which also highly correlated with yield. The optimum transplanting date for Tainung 67 was March or April, while the best time for Taichung Sen 10 transplantation was April for better yield.
