行距配置和密度对云薯401产量及主要农艺性状的影响
Effects of Spacing Form and Density on Yield and Main Agronomic Characters of Yunshu 401
摘要
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.关键词
