摘要
为建立大豆品种黑河50高产、高效的生产技术体系,以大豆品种黑河50为材料,采用二因素裂区试验设计,设密度为主处理,栽培方式为副处理,研究了种植密度和栽培方式对大豆产量及相关农艺性状的影响。结果表明:种植密度、栽培方式以及二者的互作均对大豆产量影响显著,其中处理A2B5产量最高,即密度45万株·hm-2与15cm平作组合,且与其它处理差异极显著。种植密度和栽培方式对大豆单株粒数、单株荚数和单株粒重影响显著,且种植密度的影响要大于栽培方式。
In order to establish high-yield and efficient production technology system of Heihe 50,a splitplot ex- periment was carried out with planting density being assigned to the main plot and cultivation method to sub- plot. The results showed that density, cultivation method and the interactive between density and cultivation method had a significant effect on yield,and A2B5 had the highest yield which was the combination of planting density was 450 000 plants-hm-2 and flatten culture,the difference was more significant than other treatments extremely. Planting density and cultivation method had a significant effect on grains number per plant, pods number per plant and grain weight per plant, planting density had more effect than cultivation method.
