Abstract:

In order to clarify the ratio of N, P, K content influence on deoxyschizandrin in Schisandra sphenanthera in Shangluo Shaanxi Province, and provide scientific theory for the reasonable application of fertilizer in Schisandra sphenanthera production. Three factors and four levels of orthogonal design were used to detect the different ratios of N, P, K effects on the content of deoxyschizandrin. The results showed that there was significant difference between N, P, K content (P<0.05) affects on the content of deoxyschizandrin. And the importance of the elements order was K>N>P. In this experiment condition, the best fertilization effect was N and K combining which could ensure content of deoxyschizandrin was highest in the Schisandra sphenanthera fruit. The best fertilizer content was N 12.0 g, P 0 g and K 8.0 g per plant.
