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。
Under the conditions of narrow ridge cultivation of large ridges, the method of large area contrast was used to appraise and evaluate 51 soybean varieties with different types and plant height. Ten varieties with a production potential of 4 500 kg / hm2 and above were screened out. This paper discussed the cultivation and selection of varieties with narrow rows and close planting. It was considered that applying the technology of narrow row and close planting of soybeans should absorb the core technology of constructing evenly distributed population structure of plants, and take the approach of using high density varieties (suitable density) And put forward the specific Breeding objectives of Breeding high density resistant varieties.
