为探讨高产油菜适宜叶龄移栽期,进行了杂交油菜幼苗期全株干物质积累规律和不同叶龄移栽期的试验。结果表明,油菜在五叶期前是缓慢生长期,五叶期后是快速生长期;油菜在缓慢生长期移栽较好,三叶期移栽表现适宜。
In order to investigate the suitable leaf age transplanting period for high yielding rapeseed, the law of dry matter accumulation of whole plant and seedling transplanting stage were studied. The results showed that the rapeseed had a slow growth stage before the five-leaf stage and a fast growing stage after the fifth-leaf stage. The rape transplanted in the slow-growing stage was better and the transplanting in the third-leaf stage was suitable.
