摘　　要：[目的]探寻浚单29不同肥力水平地区的适宜种植密度。[方法]研究在高产田与一般田2种肥力水平下浚单29种植密度与产量及其相关产量性状的关系。[结果]2种肥力水平下通过种植密度变化影响穗部性状来影响产量,相同密度,一般田肥力水平下,密度对穗部性状影响大于高产田对穗部性状影响。[结论]在一般田肥力水平下,浚单29最适宜密度为6.75万株/hm2,高产田肥力水平下,浚单29最适宜密度为7.50万株/hm2。[ Objective ] The suitable planting density of Xundan 29 in different ferlility levels was explored. [ Method] Influence of different plant density on yield and yield traits of Xundan29 was studied by the fertility levels of high yield field and genera field. [ Result] The results show that changes of density influenced panicle traits which influenced the yield under the two fertility levels. Under the same density, effects of density on panicle traits were higer comparing the general field fertility levels with high yield field fertility level. [ Conclusion ] In the general field fertility levels, most suitable density of Xundan 29 was 67.5 thousands plants per hm^2. In the high yield field fertility levels, most suitable density of Xun- dan 29 was 750 thousands nlants her hm^2.
