Abstract: The P fertilization tests, including pot experiments in Jiangsu province and outside experiments in Fujian province, were studied in young Chinese fir plantation. The results revealed that the P utilization percentage of Chinese fir stands in Fujian is much higher than that of the pot experiment in Jiangsu. The highest P utilization percentage is ammonium phosphate, which were 4.06% and 10.04% in pot and outside experiment respectively. In pot experiment, P fertilization increased Fe and N absorption, N and P associate fertilization increased Mo absorption, P shortage may induce Fe and N shortage, N shortage may induce Mo shortage.
