本文就不同土壤肥力、不同种植密度和施肥水平下控制性试验结果，分析了杂交油菜蓉油３号各产量构（组）成因素与产量的相关关系及其对产量贡献的大小以及经济产量、生物产量和经济系数与主要农艺性状之间的相关性。结果表明种植密度与单株产量同等重要，单株产量构成因素中以角果数贡献最大，其次为每果粒数；在产量组成中一次分枝的贡献最大，其次为主花序；有效分枝数与产量呈正相关，分枝高度与产量呈负相关，株高与生物产量呈正相关，与经济产量不相关。
In this paper, based on the results of controlled experiments under different soil fertility, different planting density and fertilization level, the correlation between yield factors and yield components of rapeseed oil No.3 and its contribution to yield, economic yield, Correlation between Biomass Yield and Economic Coefficients and Major Agronomic Traits. The results showed that planting density was as important as single plant yield. Among the components of single plant yield, the number of pods was the largest, followed by the number of per pod; the contribution of primary branches was the largest, followed by the main inflorescences; the effective branches The number was positively correlated with the yield, the branch height was negatively correlated with the yield, and the plant height was positively correlated with the biomass yield, but not with the economic yield.
