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。

Abstract: In 2004 in Sanmen Straits, Nanyang two, uses 5 broadcasts the time, 4 kind of densities two factors randomized block arrangement design. Studied week bean 11 in differently broadcasts under the time, the density condition the output constitution factor and the output change. The result indicates: In 20 processing, sow seeds by June 8th, the density is 262500/hm2 processing output is highest. But hundred grains heavy cofficient of variation is smallest in the output constitution factor, explains it is one correlation stable character.
