摘　　要：为了对威宁芜菁甘蓝标准化高产栽培提供科学依据,试验采用4因素二次正交旋转组合设计研究氮肥、磷肥、钾肥和有机肥对威宁芜菁甘蓝块根、茎叶产量、种子经济性状和种子产量的影响。结果表明:N(尿素)和有机肥对芜菁甘蓝叶片产量影响较大,硫酸钾和过磷酸钙对芜菁甘蓝块根产量和总产量影响较大;块根最佳施肥量为:尿素749.6 kg/hm2、硫酸钾749.6 kg/hm2、过磷酸钙1 000 kg/hm2、有机肥22 489.2 kg/hm2,芜菁甘蓝的产量最高为:块根达70 536.0 kg/hm2,叶片19 009.5 kg/hm2,总产量89 545.5 kg/hm2;过磷酸钙对种子产量有极显著影响,芜菁甘蓝种子最佳施肥量为尿素749.6 kg/hm2、硫酸钾749.6 kg/hm2、过磷酸钙2 000 kg/hm2、有机肥22 489.2 kg/hm2,种子产量最高达1 797.5 kg/hm2;影响种子产量的经济性状是单株有效角果数、每角粒数和千粒重,随着单株有效角果数、每角粒数和千粒重的增加种子产量明显提高。In order to give scientific basis of Brassica napobrassica（ L. ） Mill. CV. Weining The tests used secondary urthogonal design to research af- fect seed characteristic and seeds productions on nitrogen fertilizer,phosphorus fertilizer,potash fertilizer and manure. The result showed： nitrogen fertilizer and manure most effected leaves productions, potash fertilizer and phosphorus fertilizer most effected root tuber productions and totall productions. Root tu- ber best fertilized nitrogen 749.6 kg/hm2 ,potash 749.6 kg/hm2 ,phosphorus fertilizer 1 000 kg/hm2 and manure 22 489.2 kg/hm2. Root tuber produc- tions were 70 536.0kg/hm2 , leaves productions were 19 009.5 kg/hm2, totall productions were 89 545.5 kg/hm2. Phosphorus fertilizer significantly effec- ted seed productions, seeds best fertilized nitrogen 749. 6kg/hm2, potash 749. 6kg/hm2, phosphorus fertilizer 2 000 kg/hm2 and manure 22 489.2 kg/hm2 , seed productions reach to 1 797.5 kg/hm2. Affect seeds characteristic were silique numbers, grain mumber and thousand grain seeds weight, seed productions raised markedly along with silique numbers. Grain numbers and thousand grain seeds weight, maybe phosphorus fertilizer raised silique numbers so then raised seed productions. The research were science facts to high yield cultivation standardizedly of Brassica napobrassica （ L. ）Mill. CV. Weining.
