Abstract：Under field conditions, the effects of different row spacing and densities on yield and main ag-ronomic characters of Yunshu 401 were studied using split plot design with two factors including 4 kinds of row spacing ( main treatment) and 3 densities ( vice treatment) .The test results showed that the effects of different spacing forms, densities and interaction between row spacing and density on yield were all highly significantly different.Reasonably increasing density could improve yield.With the increase of row spacing, the yield showed decrease trend.Under the conditions of this experiment, planting 67 500 plants per hectare with row spacing of 70 cm was the optimal cultivation model of Yunshu 401.
