[Method] According to a randomized block design with three replicates, four fertilizer treatments and one blank control were set in field trials. Each plot had a net area of 66.7 m2, Finally, the mustard yield and economic benefit per plot among the treatments were compared. [Result] There was no significant difference in yield among the four fertilizer treatments. The agronomic traits and yield of Yongbao 2 were improved when the quantity of fertilizer was gradually increased. The treatment with 750 kg/hm2 compound fertilizer during mus- tard heading had the highest yield. However, the treatment with 450 kg/hm2 of compound fertilizer during mustard heading had the highest economic benefit. By considering both yield and benefit, 450 kg/hm2 was the optimal quantity of fertilizer required for Yongbao 2 during heading. [Conclusion] The results will provide references for future application and extension of Yongbao 2.展开更多
