| 摘 要： | 从水稻生长密切相关的生育期和农艺性状指标,探讨了黑龙江省近几年来主栽的68份水稻品种(系)的抗旱性.结果表明,栽培稻旱作较水作生育期延长、株高降低、分蘖减少,每穗实粒数降低.通过抗旱力指数法的综合鉴定得出本试验中综合抗旱能力较好的水稻品种(系)有:牡丹江22、东农425、垦稻12、牡丹江19、龙稻6号,抗旱综合指数均达到70%以上. |

| Abstract: | From growth period of rice-growing closely related to growth peroid and agronomic traits,the 68 cultivars of rice varieties(lines) of the drought-resistance in recent years of Heilongjiang province was investigated.The results showed that cultivated rice by dry cultivation than by water the growth period extended,plant height reduced,tillering reduced,grains per panicle reduced.Through drought-resistance index reached a comprehensive identification of the test,the capacity of an integrated drought-resistanc... |
