闽红两优727母本再生力和品种适宜头季机收的再生特性
|
摘要
对不育系闽红249S的再生力以及水稻品种闽红两优727作再生稻头季适宜留桩高度以及机械化生产的产量潜力进行了比较研究。结果表明:闽红249S是一个再生力强的水稻不育系,其再生率(力)为1.89,比强再生力对照佳辐占(1.67)高13.17%,差异达显著水平;闽红两优727作再生稻栽培时较适宜留低桩,留桩高度15 cm,再生季产量构成性状协调、产量高;闽红两优727头季、再生季和全年两季平均每667 m~2产量分别为597.87、320.05和917.92 kg,与机收低桩再生稻全程机械化生产主推品种泸优明占产量相当,适合作机收低桩再生稻全程机械化生产应用推广。
The ratooning ability of sterile line Minhong 249 S, the suitable stubble height and yield potential for mechanized production of Minhongliangyou 727 as ratooning rice in the first season were compared. The results showed that Minhong 249 S was a sterile line with strong ratooning ability. Its ratooning ability was 1.89, which was 13.17% higher than that of Jiafuzhan(1.67), with significant difference. Minhongliangyou 727 was suitable for ratooning rice cultivation with low stubble. When the stubble height was 15 cm, its yield components were coordinated and with high yield in the ratooning season. The yield of Minhongliangyou 727 in the first season, ratooning season and the whole year were 597.87 kg, 320.05 kg and 917.92 kg per 667 m~2, respectively, which was similar to Luyoumingzhan, the main popularized ratooning rice variety with low stubble that suitable for mechanized production. It was suitable for the application and popularization for mechanized production of ratooning rice with low stubble.
