Abstract: Experiments were conducted on container seedling of Phoebe hui from the same provenance treated with four different ratio of N, P and K, and with two different foliage fertilizer to study influence of different treatment on height growth, cold resistance indicators and field cold hardiness of seedlings. The result showed that height growth of seedlings treated with N：P：K ratio of 1:1:1 and 1:2:1, and with foliar fertilizer was significantly lower than that without foliar fertilizer. Height growth of seedlings treated with N：P：K ratio of 1:1:1, 2:1:1 and 1:2:1, and without foliar fertilizer had significant difference with the other 9 treatments. SOD, POD activity and MDA content varied among fertilization treatments. There were significant differences among three treatments of four N:P:K ratios in Pro, SS and SP contents. The average membership grade with no foliar fertilization was significantly lower than that with foliar fertilization with the same N:P:K ratio, but cold hardiness index was not significantly different. Integrated evaluation resulted that seedlings treated by N:P:K ratio 1:1:2 and foliar spraying of 5 mmol/L salicylic acid had the optimal cold hardiness and higher seedling height.
