摘　　要：为探索黔油10号的丰产栽培技术模式,采取二次通用旋转回归组合设计研究其产量与主要栽培措施(密度、氮磷、钾、硼施用量)间的数量关系,并建立了各因素与产量指标间的数学模型。进一步明确了黔油10号获得2480kg/hm2以上的丰产栽培配套技术措施优化的组合是:密度11.61～12.81万株/hm2,纯N为172.46～194.55kg/hm2,P2O5为112.47～126.88kg/hm2,K2O为74.60～92.61kg/hm2,硼砂9.72～11.52kg/hm2;其中N∶P2O5∶K2O的最佳比例是2∶1.5∶1。影响黔油10号产量的主要因素是氮肥和磷肥,其次是密度、硼肥及钾肥。For seeking the high yield cultivating technique of rape hybrid, Qianyou 10,quadratic rotational regression combination design was used to study quantity relation of yield and main cultivating technique (the density and amount of N, P 2O 5, K 2O, B applied),also a mathematical model of the main factors and yield was established. And then the model made clear that the suitable cultivating technique of excellent combination for the high yield (more than 2480 kg/ha) were density 1.161～1.281×10 5 plants/ha ,amount of N: 172.46～ 194.55 kg/ha , P 2O 5:112.47～126.88 kg/ha, K 2O:74.60～92.61 kg/ha , B:9.7155～11.5155 kg/ha .The best ratio of N∶P 2O 5∶K 2O was 2∶1.5∶1. N and P 2O 5 were the most important for yield among the factors above in Qianyou 10,and then density, B and K 2O.
