以品种为主区，种植密度为副区的二因素裂区试验表明，杂交油菜蓉油3号个体优势明显，其适宜种植密度可稍低，以发挥个体增产潜力，常规油菜中油821单株生产能力不及杂交油菜，生产上应适当密植，以发挥群体优势；种植密度主要通过影响分枝的发生。有效角果数的多少而影响产量；在产量组成中一次分枝的贡献最大，促一次分枝的发生是高产栽培的主攻方向；到成熟时干物质主要分配到角果，其中种子和果壳各占50％左右，其次为茎秆，根系占的比重较小。
The results showed that the hybrid rapeseed oil No.3 had obvious advantages and the suitable planting densities could be slightly lower in order to exert the individual yield increasing potential. The conventional rapeseed oil 821 single plant production Less ability to hybrid rapeseed production should be appropriate close planting, in order to play a group advantage; planting density mainly through the impact of branching. The number of effective pods and affect the yield; in the composition of the largest contribution to the first branch, promoting the occurrence of a branch is the main direction of high-yield cultivation; to maturity, the main distribution of dry matter to the pod, which seeds and husk Each accounted for about 50%, followed by the stalks, roots accounted for a smaller proportion.
