Fe, Zn, Cu, Mn, Ca and Mg con2 tents in rice increased first and then decreased with the increasing application rate of N fertilizer. For Diantun 502, contents and yields of Fe, Zn, Cu, Mn, Ca and Mg in rice reached the highest level at 90 kg/ hm 2 N and the rice grain yield at 180 kg/ hm 2 N. However, for Hexi 39, contents of Fe, Zn, Cu, Mn, Ca and Mg in rice reached the highest level at 180 kg/ hm 2 N and grain yield at 270 kg/ hm 2 N, which suggested that indica rice Diantun 502 was more sensitive to N fertilizer than japonica rice Hexi 39. The supply of P fertilizer reduced the contents and yields of Fe, Cu, Mn and Ca in rice, but adequate rate of P fertilizer was of benefit in increasing content and yield of Mg. Properly supply of K fertilizer could increase the contents and yields of Fe, Zn, Cu and Mn in rice. For the two rice varieties, the contents of Fe, Zn, Cu and Mn in rice attained the highest level at 90 kg/ hm 2 K2 O, but supply of K fertilizer significantly decreased the contents and the yields of Mg and Ca in rice.
