| 目的：研究半夏出干率最大时的肥料（N、P、K）配比。为执行GAP提供参考。方法：采用3因素5水平二次通用旋转组合设计，研究北方人工栽培条件下施肥对半夏等级和出干率的影响。结果：影响半夏等级和出干率的主要因素分别为N、P肥和P、K肥，其最佳施肥量为纯N 431.79 kg·hm-2、P2O5224.79 kg·hm-2、K2O 157.00 kg·hm-2。结论：半夏出干率最大时氮、磷、钾的最佳配比为4：2：1.5，此时，半夏块茎药效成分最大，临床疗效最显著。 |

| Objective: To study the combinations of fertilization, such as nitrogen (N), phosphorus (P) and potassium (K) at the time of the highest dry-slice-yielding rate of Pinellia ternata. Methods: The effect of fertilization on quality grade and dry-slice-yielding rate of Pinellia ternata was studied under the condition of purposive cultivation in northern China by using the design of 3 factors and 5 levels quadratic rotational combination. Results: N and P fertilizers mainly affected the quality grade of Pinellia ternate. P and K fertilizers mainly affected the dry-slice-yielding rate of Pinellia ternata. The best fertilizing amount of net N, P2O5, K2O were 431.79 kg·hm-2, 224.79 kg·hm-2, 157.00 kg·hm-2 respectively. Conclusion: The optimal ratio of N, P and K at the time of the highest dry-slice-yielding rate of Pinellia ternata was 4:2:1.5. At that time, the tuber of Pinellia ternata had the maximal effective component and the best clinical effect. |
