Abstract

The result of using Si in rice showed that (1)Obviously adding gross flower number and grain.(2)Raising rate of effect ear.(3)Improving maxmum LAI, grain- leaf area ratio(grain/cm2) andleafweght(mg/cm2).(4)Obviously raising accumulated dry matter after anthesis(5)Improving structure of stems and enhancing energy of autilodge.Thereby the population quality obviously improved.It was shown that the silicon fertilizer amount of 150kg/hm2 applied as the basic or tillering fertilizer was better for population quality and yield and that 225 kg/hm2 among the different silicon fertilizer amount at jointing stage for population quality and yield was best.
