摘　　要：应用 1997～ 1999年贵州省油菜区试资料对黔油 12号的生态适应性进行分析研究 ,确定了该品种的最佳生态适宜区。为探索黔油系列油菜新品种在贵州不同生态条件下的高产栽培技术模式 ,在黔油 12号生态适宜区遵义 ,采用二次最优回归设计研究其产量与主要栽培因素间的数量关系 ,建立了相应的回归数学模型。明确了黔油 12号在该生态区获得 2 80 .0 0 kg/ 6 6 7m2以上的高产配套栽培措施的优化组合是 :密度为6 32 4 .98～ 72 74 .5 4株 / 6 6 7m2 ;施纯 N 12 .4 0～ 15 .0 1kg/ 6 6 7m2 ,P2 O512 .6 1～ 14 .5 1kg/ 6 6 7m2 ,K2 O 4 .83～7.75 kg/ 6 6 7m2。N∶P2 O5∶ K2 O的最佳配比为 1∶ 1∶ 0 .5。在遵义地区影响黔油 12号产量的主要栽培因素是氮肥和钾肥 ,其次是密度和磷肥。Using the rape region trial data (1997~1999) of Guizhou province, the ecological adaptability of Qianyou12 was analysed to confirm the best ecological adaptable region of the variety. For seeking the model of high-yield cultivating technique of rapeseeds, quadratic regression design was used to study quantity relation between yield and main cultivating technique factors (the density and amount of N, P_2O_5, K_2O applied) in different ecological conditions of Guizhou. Also a mathematical model between the main factors and yield was established. And then the model cleared that the suitable cultivating technique of excellent combination for the high-yield (more than 4200kg/ha) were density of 94874.7~109118.1 plants/ha, amount of N:186.0~225.2kg/ha;P_2O_5:189.2~217.7 kg/ha; K_2O : 72.5~116.3kg/ha. The best ratio of N∶ P_2O_5∶K_2O≈1∶1∶0.5. N and K_2O Fertilizers are the most important for yield among the factors mentioned above for Qianyou 12 in Zunyi and density and P_2O_5 the second.
