【摘要】 [Objective] To explore the effects of formula fertilizer of N, P and K on the growth of annual Scutellaria baicalensis Georgi. [Method] Three factors secondary D-saturation optimal design was employed to discuss the effects of N-P-K ratio on the growth of annual Scutellaria baicalensis Georgi, thereby establishing an optimal fertilizing method. [Result] Growth indexes of Scutellaria baicalensis Georgi in fertilization treatments were higher than that in blank control group, which pointed out that the combined application of N, P and K was conductive to the growth of Scutellaria baicalensis Georgi. On the whole, the combined application of N, P and K was superior to the combination of two elements and single element. The optimal fertilization condition for Scutellaria baicalensis Georgi was 79.41 kg/hm2 N, 150.00 kg/hm2 P2O5, and 150.00 kg/ hm2 K2O. Under this condition, the content of polysaccharides in the roots of Scutellaria baicalensis Georgi was 7.4%. [Conclusion] The optimal fertilizing method was selected, which provided basis for the production of Scutellaria baicalensis Georgi.
