Effect of Different Fertilizations on the Growth Modulation and Nitrogen Fixation of Myrica rubra

In this paper the influence on growth,nodulation and nitrogen fixing when applied N,P,K chemical fertilizers,organic fertilizer and ash fertilizer to M yrica rubra (Lour) Sieb et Zucc yourdling is studied.When adopting N,P,K three factors,five levels quadric rotation cut orthogonally desigh,three regression equations of N,P,K three factors to nodule growth increment,nodule nitrogen fixing activity,shoots and leaf growth increment of Myrica rubra arc obtained.The contrast test of application shows that the application of organic fertilizer and ash fertilizer promotes the growth,nodulation and nitrogen fixation of M yrica rubra.
