摘要：

目的：研究氮磷钾肥不同配比对半夏产量和品质的影响。方法：采用3414法进行盆栽半夏肥效试验，分别应用硫酸-蒽酮比色法、BCA蛋白试剂盒进行多糖和水溶性蛋白的测定。结果：适宜的氮磷钾肥水平可分别使块茎增产22.1%(N1)、19.8%(P2)和37.0%(K2)，并且提高块茎中水溶性蛋白和多糖的含量。结论：在试验条件下，半夏氮肥经济施用量为4.67g/盆，鉴于盆栽土壤P、K含量较高，不建议施用磷钾肥。

Abstract:

Purpose:The present paper explored the changes in yield and quality of Pinellia ternate with different ratio of NPK fertilizers. Methods:The fertilizer response was detected by using the 3414 design. Content of polysaccharide and water-soluble protein were measured by Sulfuric acid-anthrone colorimetric method and Bradford Protein Assay Kit. Results: The appropriate level of NPK fertilizers increased yield of P. ternate by 22.1%(N1),19.8%(P2) and37.0%(K2) respectively as well as the amount of water-soluble protein and polysaccharide in P. ternate’s tube. Conclusion: On the experimental conditions, the recommended economical nitrogen rate is 4.67g/pot. Besides, neither potassium nor phosphorus are recommended to fertilize due to their high contents in the potting soil.
