    摘要:

    在大垄窄行栽培条件下,采用大区对比法,鉴定评价51 份株高类型不同的大豆品种。筛选出具有4 500 kg/hm2 及其以上生产潜力的品种10 份。讨论了窄行密植栽培与选用品种问题,认为研究应用大豆窄行密植栽培技术,应吸收其建造植株均匀分布群体结构的技术核心,走采用耐密抗倒高秆品种(适宜密度)的路子;并提出了选育耐密抗倒高秆品种的具体育种目标。

    Abstract:

    Fifty one soybean cultivars different in plant height, were identified. They were grown on 3 rows in 1.3 m wide ridges for 86.4~115.2 m2 for each cultvar. 10 accessions were screened with potential yield more than 4 500 kg/ha. The problems with the condensed planting model and cultivars selection were discussed. The cultvars resistant to lodging, high stem and bearing the density were suitable for condensed planting in this area. The breeding objective were proposed to select the cultivars of ligh stem with condensing telerance and lodging resistance.
