摘　　要：采用田间试验方法,研究了不同磷钾配比对茎瘤芥茎叶产量和品质的影响.结果表明:茎瘤芥高产的最佳氮磷钾肥料(N:P2O5:K2O)配比为1:0.3:0.5,最佳推荐施肥量(N-P2O5-K2O)为300-90-150kg/hm2,依此配方施肥瘤茎产量比农民习惯施肥增产21.5%,在此配方的基础上调整磷肥用量和减少钾肥用量显著降低了茎瘤芥茎的产量;在该配方上增加钾肥用量,茎瘤芥增产不显著,但显著提高了茎瘤芥茎中Vc、可溶性糖和氨基酸的含量.A field experiment was carried out to investigate the effect of different nitrogen phosphorus and potassium combinations on the yield and quality of tumorous stem mustard. The result indicated that the best NPK ratio was N ： P2O5 ： K2O= 1 ： 0.3 ： 0.5, and the best recommended fertilizer rate was N-P2O5- K2 O=300-90-150. Compared to local farmers＇ conventional fertilization practice, the above formula treatment increased the yield of tumorous stem mustard by 21.5%. Adjusting phosphorus fertilizer rate or decreasing potassium fertilizer rate on the basis of this formula significantly decreased the yield of tumorous stem mustard. Increasing potassium fertilizer rate on the basis of this formula failed to significantly increase the yield of tumorous stem mustard, but it did significantly increase the contents of Vc, soluble sugars and amino acids of the crop.
