摘要
[目的]研究浙油50在合肥市的适宜施氮量和密度。[方法]以浙油50为材料，设置施氮量（180、225、270 kg／hm2）和种植密度（22．5万、30．0万、37．5万、45．0万株／hm2）2个因素，研究不同施氮量和密度对油菜产量的影响。[结果]密度、施氮量对产量的影响达极显著水平；在该试验条件下，油菜获得高产的适宜施氮量270 kg／hm2、密度37．5万株／hm2，产量为3161．84 kg／hm2。[结论]该研究为浙油50在合肥市的推广应用提供科学依据和技术支撑。
Abstract
Objective] The aim was to study appropriate nitrogen content and density of Zheyou 50 in Hefei.[Method] With Zheyou 50 as material, effects of N application and density on economic characters and yield of Zhejiang 50 were studied.[ Result] The influence of density and applied amount of N fertilizer on yield reached very significant level.Under the condition of the experiment, the yield reached 3 161.84 kg/hm2 with the suitable N application of 270 kg/hm2 and density of 375 000 plants/hm2.[Conclusion] The study provided the scientific ba-sis and technical support for popularization and application of Zhejiang oil 50 in Hefei City.
