摘　　要：2004年在三门峡、南阳两点,采用5个播期、4种密度二因素随机区组排列设计。研究了周豆11号在不同播期、密度条件下产量构成因素及产量的变化。结果表明:20个处理中,以6月8日播种,密度为26.25万株/hm2的处理产量最高。而在产量构成因素中百粒重的变异系数最小,说明它是一个相对较稳定的性状。Used five different sowing dates and with four diffent densities two factors random configuration desige, in Sanmenxia and Nanyang of Henan province in 2004. Studies the yield factors and changes of ZhouDoul 1 in different sowing times,density factors and conditions. The results indicated that the yield of 262,500 plants/hm2 and sowing on June 8Was best among 20 treatments, and the 100 seeds weight＇s variation rat was smallest among the yield components, so that it is a relatively stable character.
