Effects of fertilization on Zizyphus mauritiana Lam.growth

The plastic shed fertilization experiment with an orthogonal experimental design L₁₆(4⁵) was conducted to study the effects of N,P,K and their recipe on the growth of Zizyphus mauritiana Lam..Ground diameter,the first branch width and crown width were selected as the growth indices.Results showed that in the growth period of Z.mauritiana,the effects of fertilization were in the order of N>K>P,and the optimal recipe was m(N) 135 g,m(P) 9.90 g, m(K) 93.60 g,ie m(N)∶m(P₂O₅)∶m(K₂O)=1∶0.17∶0.84,which provides a scientific basis for the cultivation,seedling growth and nutritious growth of Z.mauritiana in north China.
