不同肥料配方施肥对油菜产量及经济效益的影响OACSTPCD

To explore the effects of different fertilizer formulations on rapeseed yield and economic benefits,Huayouza 50 and Zhongyouza 19 were used as test varieties,and 8 fertilization treatments were set up to conduct a study on the effects of different fertilization treatments on rapeseed yield and economic benefits.The results showed that the application of com-pound fertilizer and urea resulted in the highest yield of rapeseed,with an average increase of 2 891.6 kg/hm2 and an in-crease of 7.5%compared to the control treatment(single application of urea),with a significant difference.At the same time,the economic benefits were the best,with an average income of 17 852.2 yuan per hectare and an increase of 407.7 yuan compared to the control treatment.The combination application of compound fertilizer and urea in rapeseed not only achieves yield increase,but also saves fertilizer,improves economic benefits,and achieves the goal of cost saving and effi-ciency enhancement.The optimal fertilization amount is 375.0 kg/hm2 of Xiyang compound fertilizer or rapeseed specific compound fertilizer and 300.0 kg/hm2 of urea per hectare.
