| 摘 要： | 为给寒地水稻的生产提供技术方案,通过不同高氮肥水平试验,研究了寒地水稻在产量及群体形态上的变化。结果表明:尿素施用量为362.5kg.hm-2时,龙粳18和龙粳20产量达到了最大值(11 407.41和9 710.24kg.hm-2),尿素施用量400kg.hm-2时龙粳14产量达到9 246.19kg.hm-2,并且各个处理小区增产效果明显;增施氮肥对穗长和剑叶的长度无显著影响,随着施氮量的增加,平均穗粒数具有显著增加趋势,而在最高的氮肥应用量上结实率显著降低。

| Abstract: | The changes of yield and group morphology were researched through experiments of different high-nitrogen fertilizer to provide technical solution for the high-yielding rice production in cold region.The results showed that urea fertilizer was 362.5 kg·hm-2,the yields of Longjing 18 and Longjing 20 reached maximum yields(11 407.41 and 9 710.24 kg·hm-2).Urea fertilizer was 400 kg·hm-2,the yield of Longjing 14 was 9 246.19 kg·hm-2,and the effect of increasing yield was obvious in each treatment area.Increasing N fertilizer wasn’t significant impact on panicle length and flag leaf length.Average grain number per panicle had a significant increasing trend as increasing N application,while seed setting rate significant decreased on the highest amount of N fertilizer application. |
