[Effect of N, P, K on yield and quality of Rabdosia rubescens]

To research the three fertilizer of N, P, K impacting Rabdosia rubescens on the yield and quality.

The optimum design of three factors with D-saturation design plan of N, P, K was adopted in the pot experiment.

The fertilizers of N, P, K made an obvious improvement in the growth, yield and quality of Rabdosia rubescens.

The N fertilizer plays an important role in the growth of plants. The K fertilizer makes a great impact on the accumulating of oridonin. The N, P, K fertilizers applied reasonably can make the Rabdosia rubescens high yields and improve its quality.
