适宜机插秧栽培的水稻品种筛选研究

Study on the Rice Variety Screening Suitable for Mechanized-transplanting Cultivation

以水稻品种冈优725、新优3号、金优431、金优207和Ⅱ优838为试材,考察了机插秧栽培的水稻生育期、秧苗素质、主要经济性状和产量等指标,筛选出适宜贵州省都匀市种植的机插秧水稻品种。结果表明:都匀市稻油二熟区较适宜的机插秧水稻品种为Ⅱ优838、金优431和冈优725。

The growth period, seedling quality, main economic characters and yield of five rice varieties （Gangyou 725, Xinyou No. 3, Jinyou 431, Jinyou 207 and Ⅱ You 725） were studied, in order to select the varieties suitable for mechanized-transplanting cultivation in Douyun, Guizhou Province. The results showed that Ⅱ You 725, Jinyou 431 and Gangyou 725 were more suitable for mechanized-transplanting cultivation in rice-rape double cropping system in Douyun.
