摘　　要：在互助县台子乡,进行了磷肥施用量对春油菜产量和千粒重的影响研究。结果表明：OPT＋1/2P处理产量最高,为6 261 kg/hm2;推荐施肥方案OPT处理产量为6 068 kg/hm2,居第2位,较无肥对照增产24.2%,较减磷处理增产8.6%~10.9%。The effects of application amount of phosphorus on the yield and 1 000 seeds weight of Brassica napus were studied in Taizi Town,Huzhu County.The results showed that the yield was the highest（6 261 kg/hm2）with the treatment of OPT＋1/2P.The yield with the treatment of OPT took the second place（6 068 kg/hm2）,which increased by 24.2% than that of no fertilizer,and decreased by 8.6%-10.9% than that of reducing the amount of phosphorus.
