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。
The effects of different N application rates on the yield and yield components of hybrid rapeseed Qianyou 18 were studied. The results showed that the effective pod number per plant was the highest (562.4) when the net N was increased to 300 kg / hm2, , With the highest total number of stems per plant (50), and the best yield (1 068.01 kg / hm2). Under the conditions of this experiment, the high-yielding fertility of Qinyou 18 could be N 300 kg / hm 2 .
