在大田条件下，采用4种行距（主处理）和3种密度（副处理）两因素裂区设计，研究了不同行距、不同密度对云薯401产量及主要农艺性状的影响。结果表明，不同行距配置、不同密度以及行距与密度互作间产量均存在极显著差异，适度增加密度可以提高产量，随行距的增大产量有降低的趋势。本试验条件下，云薯401行距70 cm、种植密度6．75万株／hm2为最优栽培模式。

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.
