不同肥料配方施肥对油菜产量及经济效益的影响

Effects of Different Fertilizer Formulations on Yield and Economic Benefit of Rapeseed

以华油杂50、中油杂19为供试品种,设置8个施肥处理,分析不同肥料配方施肥对油菜产量及经济效益的影响。结果表明:复合肥+尿素处理的油菜产量最高,平均为2891.6 kg/hm^(2),较对照(单施尿素)增产7.5%,差异达极显著水平;且该处理经济效益也最好,平均收入达17852.2元/hm^(2),较对照高407.7元/hm^(2)。复合肥与尿素配施在实现油菜增产的同时,节省了肥料,提高了经济效益,达到了节本增效的目的。综合分析,本试验条件下,以施西洋复合肥或油菜专用复合肥375.0 kg/hm^(2)+尿素300.0 kg/hm^(2)为宜。

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 compound fertilizer and urea resulted in the highest yield of rapeseed,with an average increase of 2891.6 kg/hm^(2)and an increase 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 17852.2 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 efficiency enhancement.The optimal fertilization amount is 375.0 kg/hm^(2)of Xiyang compound fertilizer or rapeseed specific compound fertilizer and 300.0 kg/hm^(2)of urea per hectare.
