Abstract:
Taking jujube variety ‘Qiyue Xian’ as material,“3414” fertilization program was used to study the effect of different nitrogen(N),phosphorus(P),potassium(K) ratio on production of jujube.By deficiency analysis and multiple regression analysis,the research got the best yield and maximum yield under the relative amount of fertilizer.The results showed that N,P,K fertilizer could significantly improve the yield of the jujube.The order of the effect was K>N>P.The fertilization (N,P2O5,K2O) of the best treatment 6 (N,P2O5,K2O were 0.23,0.12,0.2 kg/plant) could improve the yield by 50% was 0.23 kg/plant,0.12 kg/plant,0.2 kg/plant.The maximum amount of fertilizer were N 0.22 kg/plant,P2O2 0.06 kg/plant,K2O 0.34 kg/plant by model analysis,of which the maximum yield was 12.02 kg/plant.
