摘　　要：通过田间试验研究不同肥料配施对穿心莲生长和内酯含量的影响。结果表明:增施钾磷肥或有机肥的平衡施肥对穿心莲的生长有明显的促进作用。不同氮磷钾和有机肥配施处理较仅施氮肥的对照产量增加16.85%-26.67%,平均增产22.07%。穿心莲内酯含量增长0.70-8.21个百分点,相对提高2.82%-33.08%;经济收入提高5202-8237元/hm2,施肥产投比为4.50-8.22∶1。Experiment of high yield, high efficiency fertilization technology was carried out. The result showedbalanced fertilization of potassium, phosphorus and organic manure application could obviously promote the growth of creat, yield increased by 16. 85 - 26. 67% averagely 22. 07%. The content of Andrographolide enhanced by 0. 70 - 8.21 percent and 2. 82 - 33.08%, and the profit raised by 5202 - 8237Yuan/hm2 with the value cost ratio 4, 50 - 8.22： 1.
