以晋豆30号为材料，通过田间试验，研究不同种植密度对晋豆30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、单株荚数、单株粒数、单株粒重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；不同种植密度下晋豆30号产量差异显著；15万~27万株/hm2种植密度范围内，产量随密度的增加而增加，密度为27万株/hm2时产量最高，达2680.8 kg/hm2；当密度增加到30万株/hm2，产量则有所降低。
以晉豆30號為材料，通過田間試驗，研究不同種植密度對晉豆30號產量及產量構成因素的影響。結果錶明：種植密度對產量構成因素有顯著影響，其中，分枝數、單株莢數、單株粒數、單株粒重在不同種植密度下差異均顯著，且與種植密度有顯著的負相關性；不同種植密度下晉豆30號產量差異顯著；15萬~27萬株/hm2種植密度範圍內，產量隨密度的增加而增加，密度為27萬株/hm2時產量最高，達2680.8 kg/hm2；噹密度增加到30萬株/hm2，產量則有所降低。

Taking Jindou 30 as materials,by the field test,the effect of planting density on yield and yield components of Jindou 30 was studied . The results showed that planting density had a significant effect on yield components factors ,the difference among the number of branches ,number of pods per plant,grain number per plant and grain weight per plant were significant under different planting density ,and planting density had a significant negative correlation.There was significant difference of Jindou 30 yield under different planting density;150 000~270 000 plants/hm2 planting density range,yield increased with the increasing of the density,density of 270 000 plants/hm2 yield was the highest,up to 2 680.8 kg/hm2.As the density increased to 300 000 plants/hm2,production reduced.
