3414 test results from 2007 to 2009 in Haimen of Jiangsu Province showed that: 1）soil N, P, and K storages could not satisfy rape need sufficiently and applying N, P and K fertilizers currently still could increase rape yield. The optimal uses of N, P and K fertilizers per 667m2 were N 12.5-14kg, P2O5 4-4.5 kg and K2O 4-5kg. 2) per 100kg rapeseed used N 5.50 kg, P2O5 1.00 kg and K2O 5.14 kg and N 4.65 kg, P2O5 0.90 kg and K2O 4.60 kg in the total-fertilizer zone and nutrient-deficient zone, respectively. 3）the use ratios of fertilizers in the total-fertilizer zone were N 22.96%-51.57% with a mean of 37.46%, P 5.07%-19.18% with a mean of 9.94%, K 9.51%-52.67% with a mean of 34.90%.
