牛蒡高磷处理产量偏高，高氮中磷处理产量也较高，其施肥量以６６６．７ｍ２施Ｎ２０ｋｇ、Ｐ２Ｏ５２５ｋｇ，Ｎ：Ｐ２Ｏ５：Ｋ２Ｏ＝１：１．２５：０．５或１：１．６６７：０．４较为适宜。
The yield of high-phosphorus-treated burdock was high and the yield of high-nitrogen medium-phosphorus was also high. The fertilization amount was N20kg, P2O525kg, N: P2O5: K2O = 1: 1.25: 0.5 or 1: 1 at 666.7m2. 667: 0.4 is more appropriate.
