【摘要】 秦油2号、宁杂1号等中晚熟杂交油菜秋发、冬壮、春稳、活熟的栽培技术是本地区超高产的有效技术途径。冬前群体和个体主要形态指标与产量显著正相关。增加角果数的潜力最大，是秋发冬壮栽培的主攻目标。秋发冬壮栽培的群体叶面积发展协调，茎技结构配置合理，结角密度大，角果皮面积指数高，结角成熟期于物质积累多，耐肥抗寒抗倒伏，产量高。更多还原

【Abstract】 The "autumn vigorous, winter sound, spring stable growth and living ripeness" was an efficlent method for extro-high yield of middle-late hybrid rape variety.The main characters of population and single plant were positive correlated to seed yield significantly. Under the cultural practices, the leaf area of population developed reasonably, pod density, pod area index and dry matter accumulated in seed filling period increased, the cold and lodging resistance were strong, and extro-high yield obtained.更多还原
