不同肥料在油菜上的施用效果

The application effect of different fertilizers on rape seed

以油菜(Brassica napus L.)品种大地199为试验材料,设置不施肥、常规施肥、常规施肥+沃农丹微量元素、宜施壮40%长效缓释专用肥、洋丰40%油菜专用肥、三宁40%油菜专用肥、祥云40%油菜专用肥7个处理,研究不同施肥处理对油菜生物性状、经济性状、经济效益和农学利用率的影响。结果表明,与常规施肥相比,施用不同肥料对油菜的越冬后叶片数无显著影响,对株高、分枝位置、一次分枝数有不同程度影响;施用宜施壮40%长效缓释专用肥、三宁40%油菜专用肥、祥云40%油菜专用肥显著提高了油菜的产量、单株角果数、千粒重,经济效益分别增加了41.13%、41.74%、42.62%,肥料农学利用率分别增加了4.1、3.9、4.0 kg/kg。

The effects of different fertilization treatments on the biological characteristics,economic characteristics,economic benefits,and agronomic utilization efficiency of the rapeseed(Brassica napus L.)cultivar of Dadi 199 were studied.The seven treatments were set up as follows:No fertilization,conventional fertilization,conventional fertilization+Wonongdan microelements,40%long-acting slow-release special fertilizer of Yishizhuang,40%rapeseed special fertilizer of Yangfeng,40%rapeseed special fertilizer of Sanning and 40%rapeseed special fertilizer of Xiangyun.The results showed that compared with conventional fertilization,the application of different fertilizers had no significant effect on the number of leaves of rapeseed after overwintering,but had varying degrees of impact on plant height,branching position,and number of primary branches.The yield,number of pods per plant,and 1000-seed weight of rapeseed significantly increased under the treatments of 40%long-acting slow-release special fertilizer of Yishizhuang,40%rapeseed special fertilizer of Sanning and 40%rapeseed special fertilizer of Xiangyun.The economic benefits increased by 41.13%,41.74%and 42.62%,respectively,and the fertilizer agricultural utilization efficiency increased by 4.1,3.9 and 4.0 kg/kg,respectively.
