Abstract: Based on the normal production of broomcom millet spacing 30cm, density of seedling 70000/667m2 as control, research of broomcom millet in different wide spacing treatments, Keeping a full stand at 30000/667m2 plant of sparse sowing density, whether it can improve the propagation coefficient of its yield, for trying to find a better row spacing treatments, resulting in actual production application of broomcorn millet in order to replace the conventional narrow spacing and high planting density, as a result, broomcom millet could be popularized and applied of the large area in the actual production.
