Abstract: The leaching and residual characteristics of Cl- in saline soil were studied after the chlorine fertilizer application,adopting simulated soil column method.Also the application effects of potassium sulfate and potassium chloride on cotton yield,soil salinity and Cl- residue were studied through plot trials with different soil salinities.Simulated experiment results showed that the added Cl- was very easy to be leached out.The possibility of Cl- leached amount out of 0-40 cm soil layer under normal annually rainfall could reach as high as 24-74.7 times of the added amount,without considering its upward movement.Plot trials results showed that cotton yield did not increase statistically with the application of two kinds of potassium fertilizer,under the soil available K content of 332 mg/kg,while it increased statistically under the soil available K content of 189.5 mg/kg.Cotton yield did not differed remarkably between two kinds of potassium fertilizer application under light salinity soil,while potassium sulfate application showed remarkably higher yield-increasing effect compared with potassium chloride,under mid salinity soil.The salinity and Cl- content in 20-40 cm soil layer increased obviously under higher amount application of potassium chloride.
