| 摘 要： | 针对哈尔滨地区种植的不同熟期、不同穗型的水稻品种进行生育期调查和植株测定。结果表明:黑龙江省水稻品种(系)生育期越晚穗粒数越多,在哈尔滨地区种植水稻随着生育期增加产量呈先增后减的趋势,生育期在9月15日左右成熟,即8月2日左右抽穗的水稻产量最高。

| Abstract: | The growth period and plant traits were investigated on rice varieties with different maturity and panicle type in Harbin and the results showed that the later the growth period of rice varieties was,the much more grains per panicle were.With the increase of growth period,the yields of rice varieties increased first and decreased then.The varieties are easy to reach high yield when the maturity time is September 15 or so and the heading time is around August 2. |
