| 摘 要： | 以苦荞晋荞麦6号为材料,通过田间试验,研究了不同种植密度对苦荞晋荞麦6号产量及产量构成因素的影响。结果表明,种植密度对产量构成因素有显著影响,其中,分枝数、单株粒数、单株粒质量在不同种植密度下差异均显著,且与种植密度有显著的负相关性;不同种植密度下晋荞麦6号产量差异显著;30万～120万株/hm2种植密度范围内,产量随密度的增加而增加,密度为120万株/hm2时产量最高,达2479.67kg/hm2;当密度增加到150万株/hm2时,产量则有所降低。

| Abstract: | Yield and yield composition of Jinqiao 6 under different planting densities were studied by field experiment.The numbers of branches,seed number per plant and grain weight per plant were significantly different under different densities,which had a significant negative correlation with planting density.Yield under different densities were significantly different,with the highest yield 2 479.67 kg /hm2 under 1 200 000 plants/hm2.The yields were increased along with the increase of density which was from 300 000 to 1 200 000 plants/hm2;when the density was above 1 500 000 plants/hm2,the yield declined. |
