| Abstract: | The critical values of tolerance to Cl concentrations for wheat on neutral and calcareous purple soil were estimated to be 500 ppm and 200-400 ppm, respectively. Correspondingly, the chlorine content of wheat grains and straws and of the shoot at the tillering stage was 0.06%, 1.47-1.58%, 2.12-2.49% respectively on neutral purple soils. On calcareous purple soil, it was 0.06%, 1.51-1.63%, 2.11-2.34% respectively. No unfavorable effects on the yield and quality of wheat were found within the ranges of the above values. |
