| 摘 要： | 为了研究长穗小麦新品系86(306)对密度和肥力变化的反应,试验设置了4种密度和4种肥力水平。结果表明,在密度为345万/hm2下,施肥N:315 kg/hm2,P2O5:240 kg/hm2的处理可以使长穗小麦86(306)的产量达到最大值;产量构成因素穗数、穗粒数和千粒重分别在密度345万/hm2,施肥N:315 kg/hm2,P2O5:240 kg/hm2;密度120万/hm2,施肥N:415 kg/hm2,P2O5:240 kg/hm2和密度345万/hm2,施肥下N:315 kg/hm2,P2O5:240 kg/hm2达到极大值。

| Abstract: | In order to understand the impact of density and fertility to yield and its factors for long spike wheat 86(306),4 density levels and 4 fertilities levels were used.The result showed under the density 3.45 million/hm~2 and fertilizing N:315 kg/hm~2,P_2O_5:240 kg/hm~2,the yield got maximum value among different treatments;its factor spikes/hm~2,kernel numbers per ear and 1000-kernel weight got maximum value under different treatments of the density 3.45 million/hm~2 with fertilizing N:315 kg/hm~2,P_2O_5:240 kg/hm~2,the density 1.20 million/hm~2 with N:415 kg/hm~2,P_2O_5:240 kg/hm~2 and the density 3.45 million/hm~2 and fertilizing N:315 kg/hm~2,P_2O_5:240 kg/hm~2. |
