土壤缺水對水稻與陸稻期作間生產之影響(一)生長與產量之差異

Abstract

本項試驗以本省陸稻品系2個，日本陸稻品種4個，菲律賓陸稻品種1個以及本省水稻推廣品種4個為材料，分別於1995年第一、二期作栽種於臺灣省農業試驗所農場，以探討土壤缺水對稻穀產量及產量構成性狀之影響，並比較水、陸稻乾旱衝擊之差異。 Drought, or soil water deficit, is known to affect the growth and yield of crop production including rice. With a special two crops system and an unique climatic condition, however, no research has been conducted to compare differences in growth behavior between lowland and upland rice to limited soil moisture in two crops in Taiwan.
