Abstract: Different banding planting width of 20, 40, 60 and 100 cm with line width of 20 cm and sowing whole district were conducted in field, the effect of seeds distribution on population dynamics, yield and yield three factors were studied. The results showed that ear number and tiller number of per plant at all growth stages increased with the increase of planting width, ear number and tiller number of per plant reached the least when planting width was 20 cm, ear number and tiller number of per plant reached the maximum when sowing whole district; the variation of thousand-grain weight and kernels number of per spike was in the opposite to hectare spike number; thousand-grain weight and kernels number of per spike reached the highest when the planting width was 20 cm, and they reached the lowest when sowing whole district. The yield increased first and then decreased, the yield-increasing effect was the best when planting width was 20-60 cm, the yield was the lowest in sowing whole district treatment. The results suggested that suitable wide planting was benefit to the increase of group growth and yield of wheat compared with equal line width planting and sowing, the percentage of ear-bearing tiller and yield ratio were higher. In the experiment condition, 60 cm planting width had the highest yield, more tiller and high percentage of ear-bearing tiller.
