Abstract:
Objective The effect of fertilizer application on yield and quality of Notopterygium forbesii was studied in order to provide a theoretical basis for high quality and yield planting.Methods With various nitrogenous(N) and phosphorous(P) fertilizer formula,the field tests were carried out to determine the yield,extract content,and essential oil content,from the root of N.forbesill.Results Showed that various proportion of fertilizer had a great affect on yield,extract content,and essential oil content,and the treatment with N2P2 was the highest.The yield in the treatment with N2P2 increased 43.33%,the extract content increased 17.95%,and the essential oil content increased 43.48% as compared with CK.Different rates of fertilizer application had a certain effect on weight and diameter in the root of N.forbesii,and the N2P2 was the best.Each treatment had a significant effect on diameter in the root of N.forbesii in comparision with CK.Conclusion Amount and ratio of N and P fertilizers have a greater influence on the yield and quality,while improper application could reduce the yield and quality.
