简介：在盐的sodic土壤下面的标志叶子和影响因素的光合的率调节的网络在米饭的完整的标题阶段被调查。米饭的光合的率离开的网在非盐的sodic和盐的sodic土壤处理在一天内显示出一条双山峰曲线。网的第一座山峰分别地，而第二在14:00两个都达到顶点，光合的率在盐的sodic和非盐的sodic土壤处理出现在9:0010:00和9:00。网的正午消沉光合的率总是不管非盐的sodic或盐的sodic土壤条件出现了。另外，网光合的率显著地减少了在整天在非盐的sodic条件下面与那相比在盐的sodic下面调节。一些差别在在网络之间的关联字符被观察光合的率和所有影响因素在9:0013:00期间。在非盐的sodic条件下面，日报在一天内的光合的率主要是的网的变化由有气孔的传导力引起了，并且限制价值和有气孔的因素用作决定因素；而在盐的sodic应力下面，日报在一天内的光合的率主要是的网的变化由包括轻紧张和空气温度的非有气孔的因素引起了。
