| 摘 要： | 本文就人参施Ｎ，Ｐ，Ｋ肥对干物质积累以及对Ｎ，Ｐ吸收的动态进行了３年田间栽培试验研究，结果表明，施肥对四，五，六年生参根增重率分别为５．１％，３７．４％，４１．１％，对参根Ｎ含量分别提高１９．８％，１５．１％和８．７％，茎中Ｎ含量变化与根基本相同，而叶中Ｎ含量随参龄增加呈降低趋势。人参各器官中Ｐ含量变化规律不明显。六年生各生育期根重和Ｎ积累变化规律是：母根萌发至收获的根重变化经历了从减重到增重的过

| Abstract: | A three -year studies on applying N, P, and K affecting dry matter accumulation and N and P uptake of Ginseng were reported in the current paper. The results indicated that fertilization increased Ginseng root weights by 5. 1%, 37. 4, and 41.1% and increased N contents by 19. 8%, 15. 1 % , and 8.7% for 4,5, and 6 years old Ginseng respectively. The variation of the N contents in stalk and root was similar but the N content in leaf decreased with the ages of Ginseng. There was no significant different for P contents in different plant organs. The root weight and N accumulation for 6 -year-old Ginseng varies as: the root weights from germination to harvesting periods decreasing first and then increasing and applying fertilizers making this .turning point one growth duration early, and the accumulation of N and P in root showing the same trend. |
