摘　　要：通过对氮肥不同施用量对杂交油菜黔油18号制种产量和产量构成因子的影响研究,结果表明:当施纯N增加到300 kg/hm2时,单株有效角果数最多(562.4个)、单株总茎枝数最多(50个)、产量表现最好(1 068.01 kg/hm2),在本试验条件下,黔油18号制种高产施肥水平以施纯N 300 kg/hm2为宜。Different N application amounts were tested in seed production of Qianyou 18 to study the effects on seed yield and yield composition factors. The results show that the highest seed yield, effective pods per plant and total stem and branch per plant was 1068.01 kg/ha, 562. 4 and 50 pod/branch respectively when 300 kg/ha of pure N was applied under the test condition.
