摘要
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)、P_2O_5 224.79 kg·hm^(-2)、K_2O 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 ofPinellia ternate. P and K fertilizers mainly affected the dry-slice-yielding rate of Pinellia ternata. The best fertilizing amount of net N, P205, 1（20 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.
