| Abstract: | In order to provide the theoretic perspective for fertilizer and water save for chinese juniper of highway under drip irrigation. This study carried out optimize composition experiment of three factors among the irrigation, times of irrigate, fitting of N and P fertilizer for the height of chinese juniper under the condition of drip irrigation by cross experiment methods. The result indicates that the optimum combination of the three factors is at 4 times of irrigation, irrigation quota 150 m3/hm2, NIP ratio 2.5. |
