研究了籼爪交和粳爪交杂种在长沙、三亚两地农艺性状和干物质产量的表现。由引进爪哇稻品种所配的籼 /爪和粳 /爪交杂种 F1 代表现为植株高大 ,生长茂盛 ,具有强大的干物质产量优势。绝对干物质产量 (单株穗期干重 )为 :籼爪杂种 >粳爪杂种 >对照 (籼籼交杂种 ) ,干物质生产率 (单株日干物质产量 )为 :籼爪杂种 >粳爪杂种 >对照。供试籼爪交和粳爪交组合感光性较强。
The agronomic traits and dry matter yields of indica and japonica hybrids in Changsha and Sanya were studied. The indica / pawpaw and japonica / pawpaw F1 hybrids introduced by the introduction of Javanese rice varieties are now representative of tall, vigorous plants with strong dry matter yield advantages. The absolute dry matter yield (dry weight per plant) was: Indica / indica hybrids> Japonica hybrid> control (indica indica hybrid), dry matter productivity (dry matter per plant per day): Indica / indica hybrids > Control. Test indica claw and japonica claw to pay a combination of more sensitive.
