Abstract: A field experiment was conducted to analysis the absorption,distribution and translocation of nitrogen(N),phosphorus(P) and potassium(K) of spring maize in Gongzhuling and Qian′an of Jilin Province.The results were shown as follows,N and P uptake after silking in Gongzhuling were 26.1%,20.5% of total uptake respectively,which were 28.0%,25.8% in Qianan.K uptake before silking in Gongzhuling and Qianlan were 84.2%,92.3% of maximum K uptake respectively.Trends of N and P accumulation coincided with the transfer of growth center,while K not.The maximum accumulation of N,P and K in Gongzhuling was higher than that in Qianan,while the accumulation of K in Gongzhuling was a little lower than that in Qianlan at maturity stage.Regional difference was related to better soil nutrients,higher accumulated temperature,more rainfall and longer growth period in Gongzhuling.Xianyu335 shows a higher accumulation of N,P and K than Zhengdan958 in both regions.

Key words: Spring maize, N, P, K
