Abstract:

The text of split-plot design, in which three mainly cultivated SCN resistant soybean varieties(Kangxian No.4, No.6, No.8 )in Henglongjiang province were taken as the main plot and 5 planting densities as sub-plot， compared and analyzed the agronomic characteristics and yield in different planting densities. The result indicated that 100-seed weight and seeds per pod were not significantly different with 5 densities; But pods per plant, seeds per plant and seed weight per plant were significantly different with 5 densities and was decreased with the increase of planting density. Suitable density of Kangxian No.4 was about 260,000 plants per ha, Kangxian No.6 was about 230,000 plants per ha, Kangxian No.8 was suitable for high density.
