In order to find out the nutrient requirement of Phyllostachys edulis in winter shoot growing period, the dynamic changes and accumulation rules of N, P and K contents in winter shoots were studied. The result showed that the N, P and K contents in shoot body were much higher than that in sheath. As shoot growing, the contents of the three elements in shoot body showed the change trend of decreaseing at first and then increasing slightly, but in sheath, the dynamic changes of N, P and K contents were not obvious. After sprouting, the nutrient accumulation speed and amount in winter shoot increased gradually as its growing up. By February, the N, P and K in winter shoots accumulated up to 2 807.62 g·hm-2, 305.57 g·hm-2 and 610.23 g·hm-2 respectively. The nutrient accumulation (Y, g) in shoot had a significant correlation with the shoot high (H, cm) and diameter (d, cm), and the model of N accumulation to H and d is Y=-2.068 9+0.001 0 H+0.626 6 d(R2=0.807 2).
