【摘要】 以分枝型和主茎型各两个品种为材料，３种密度处理，２因子裂区设计试验，分析种植密度对大豆生长发育与产量的影响．结果表明：在中等栽培水平下，分枝型中熟、中晚熟品种以每穴单株、每公顷１６．０—１７．０万株，主茎型中熟品种以每穴双株、每公顷２０．０—２２．０万株比较适宜。更多还原

【Abstract】 A split-plot trail was conducted to investigate the effects of 3 plant densities on growth and yield of branching and main-stem types of soybean. The results showed under middle level of cultivation, the fit density of plants/ha for mid-maturing and mid-late maturing varieties in branching type was 0.16-0.17 million by sown single plant in a opening, while that for mid-maturing varieties in main-stem type was 0.2-0.22 million by sown double plants in a opening.更多还原
