Study on High-yield Planting Density of Soybean in Northwest Guizhou
[Objective]The study aimed to choose the best planting density of Bidou No. 2.[Method]From 2006 to 2008,took Degou,Hezhan-gshuangping,Heguantun in Bijie of Cuizhou as three test locations, set six treatment groups, and determined all the indexes.[Result]The plant height, height of the bottom pod and internode length increased as density increased, meanwhile, main stem nodes, branch number, stalk weight decreased, and the pods number per plant, grain number and grain weight gradually decreased.[Conclusion]Treatment ④ was the best planting density, and the highest yield reached 2 982.5 kg/hm2.
