| 摘 要： | 为研究栽培远志对氮、磷、钾的需求特性，指导产区大田生产，采用三因素三水平正交试验设计。结果是氮、磷、钾在不同施用条件下，远志单产有显著性差异。结果发现栽培远志氮、磷、钾的合理施肥比例为1:1.04:1.34，每公顷年平均施肥量为尿素390kg，重过磷酸钙405kg，硫酸钾480kg。

| Abstract: | Objective: Study the fertilizer requirement characteristics of P. tenuifolia on nitrogen fertilizer、fertiphos and potash manure to improve cultural practices in producing region. Method: The experiment was determined by the orthogonal experiment design of three factors and three deals. Result: There is significance difference for the yield per mu in different amount of fertilizer applied. Conclusion: The proper fertilizer proportion of P. tenuifolia is N:P:K=1:1.04:1.34, and the amount of fertilizer applied is annually urea 26kg, concentrated superphosphate 27kg and potassium sulphate 32kg for per 667m2. |
