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. The effects of different ratios of P and K on the yield and quality of stem and mustard stems and leaves were studied by field experiments.The results showed that the best N, P2O5 and K2O ratio of 1: 0.3: 0.5, and the optimum recommended fertilizer (N-P2O5-K2O) is 300-90-150kg / hm2. According to this formula, the yield of stems increased 21.5% compared with that of peasants. Based on this formula, Reducing the amount of potassium fertilizer significantly reduced the yield of stem mustard; increasing the amount of potassium fertilizer in the formula did not increase the yield of tumorous stem mustard, but significantly increased the contents of Vc, soluble sugar and amino acid in stem stem mustard.
