ABSTRACT
Objective:
To estabolish te fertilization index of nitrogen (N), phosphorus (P), and potassium (K) and regression model of Epimedii Wushanensis Herba, and to explore the optimization of fertilization.Methods:
The design of the fertilizer element 3 and factor 4 was introduced, the effect test of N, P, and K fertilizers was laid out and the test data were collected and analyzed statisticly.Results:
An empirical model of the relationship between Epimedii Wushanensis Herba and the contents of Icariin and epimedin C to N, P, and K were established and optimized to analyze the interaction among the tested factors.Conclusion:
Yield and quality of Epimedii Wushanensis Herba are lower significantly without one of N, P, and K and the optimization treatment efficiency is N2P2K2. Single-factor analysis shows that the yield and the contents of active ingredients Icariin and epimedin C increase and then decrease steadily with the increase of the N, P, and K application. The first order interaction analysis indicates that there exists an interaction range between N and P, N and K, P and K. The synergistic and antagonistic effects are shown in the lower and higher.
