摘要: 为探索湖北省天门市种植再生稻适宜的留桩高度,以丰两优香1号为试验材料,开展了不同留桩高度对其生长发育动态和产量影响的试验。结果表明,在15~45 cm的留桩高度范围内,随着留桩高度的增加,丰两优香1号再生季稻的生育期缩短,株高升高,再生苗数增多,穗长、穗粒数均降低,有效穗数、再生率均增加,再生季稻产量以45 cm留桩高度处理的最高,为4 570.45 kg/hm2。从生育期、再生率、产量上综合分析,丰两优香1号再生季应尽可能留高桩。

Abstract: : In order to explore the appropriate stubble height of ratooning rice in Tianmen city, Hubei province, taking the Fengliangyouxiang No.1 as experimental materials, the effects of different stubble height on the growth and development dynamics, yield of ratooning rice were studied. The results showed that, as the stubble height of Fengliangyouxiang No.1 increased at the range of 15~45 cm, the growth period shortened, the plant height increased, the ratooning tillers increased, panicle length and grain number per panicle all decreased, effective panicles, and ratooning rate increased, the stubble height of 45 cm showed the highest yield, was 4 570.45 kg/hm2. Comprehensive analysis of the growth period, ratooning rate and yield,the highest stubble height should be reserved for ratooning cultivation of Fengliangyouxiang No.1.

Key words: ratooning rice, Fengliangyouxiang No.1, stubble height, growth and development dynamics, yield
