Four levels of nitrogen (N: 0, 150, 300, 450 kg/hm2)，phosphorus (P: 0, 75, 150, 225 kg/hm2) and potassium (K: 0, 150, 300, 450 kg/hm2) were fertilized to sugarcane fields in order to study N, P and K accumulation in sugarcane plant and their influence on sugarcane yield and quality. The results indicated that sugarcane yield significantly increased with the increase of K, while did not influenced obviously by N and P levels. Sugar yield increased significantly with the increases of P and K levels, but did not influenced by N level. Sugar content did not change directly with the levels of N, P and K. The nutrient components in plant increased with the increase of N, P and K levels, the accumulation of N, P and K in sugarcane were in order of stalk＞tip of plant＞dull leaf for N and P while in order of tip of plant＞stalk＞dull leaf for K.
