Abstract

In the arid valley of the upper reaches of the Minjiang river,combined nitrogenous and phosphorus fertilizers were applied on the one-year-old seedlings of Pinus radiate.An appropriate amount of fertilization was explored to provide the basis of fertilization management of yung P.radiate in the arid valley.Different combined fertilizations of nitrogenous and phosphorus were studied based on the randomized blocks design.The results showed that in comparing three treatment groups with control groups,the first and second treatments significantly increased the ground diameter and height of P.radiate.The third treatment merely significantly increased the ground diameter.Under the condition of this study,the recommended fertilization amount was 30 grams of urea and 150 grams of calcium superphosphate per plant for the one-year-old P.radiate.
