钩藤施用氮磷钾的肥效试验

Effects of nitrogen,phosphorus and potassium on Uncaria rhynchophylla facilities cultivation

为钩藤高产创建施肥决策,提高钩藤生产效益提供科学依据,采用3414肥料试验方案开展了钩藤的N、P、K肥料效应研究。结果表明:钩藤的株高、茎粗、分枝数均与N、P、K呈线性关系,株高与N、K较相关,相关系数为0.99;茎粗与P最相关,相关系数为0.99;分枝数、折干率与N最相关,相关系数0.97;处理⑥的配方(N∶P∶K=20∶12∶16)最接近最佳施肥量,其第2年的经济效益为574.6元/667 m2,超过大豆138.59元/667 m2,第3年的经济效益翻几番,因而用耕地种植钩藤比种大豆的效益高。

In order to optimize fertilization technique and realize high yield and fine quality of Uncaria rhynchophylla,effects of N,P,and K on Uncaria rhynchophylla was studied through'3414'fertilizer trial.The results showed that the plant hook,height,and stem diameter,the number was linear regression with N,P,and K,the plant height and N,K is related,the stem diameter and P was the most relevant,the number of branches,Fold dry rate and N was the most relevant,the six recipe is closest to optimum fertilization,in the second year,the economic benefits of six processing formula 574.6 yuan was more 138.59 yuan than the soybean planting,in the third year beyond the economic benefits over a few comments,Thus use arable land to plant Uncaria rhynchophylla which the effective higher than the soybeans.
