人工雨水處理對水稻產量構成要素之影響

Abstract

本試驗目的在於探討水稻各生育階段施以人工雨水處理所造成的影響，尤其著重於有關不稔實率的研究，其結果如下： 1.於水稻不同生育期施以人工雨水處理，可以延遲抽穗期，長期處理之效果較為明顯；稉稻臺南5號所受之影響較秈稻臺中秈3號為大。 The purpose of this study was to examine the effect of rainfall on the yield performance of rice crop in the first and second crop season. Potted rice plants at different developmental stage were subjected to artificial rein by spraying water for 8 hours per day at a rate of 100mm/hr. Two cultivars, Tainan 5 (Japonica type) and Taichung Sen 3 (Indica type) were tested in Taichung, Taiwan in 1980.
