Abstract
Based on the fact that Fe toxicity which is usually characterized by leaf oranging and low yield canbe obviously subdued by application of Si or Mn due to counteraction between Fe and Si or Mn. A potexperiment was conducted with four treatments of CK, Si, Mn and Si+Mn to further study the effect ofcombined application of Si and Mn on rice growth on red earths. Water-soluble Si, Fe and Mn were measured,and electron probe was used to study Si, Mn, Fe and Ca in root cross sections. Combined application of Si andMn could increase water-soluble Si and Mn but reduce water-soluble Fe, thus being favorable for correctingFe toxicity. Electron probe study showed obvious differences of Si, Fe, Mn and Ca in rice roots betweenCK and the other three treatments. The combined application of Si and Mn could reduce leaf oranging andimprove rice growth. The Si+Mn treatment had a higher plant height, lower number of oranging leaves anda 25.0% higher rice yield than CK and showed a better effect on rice growth than the treatment of sole Si orMn.
