Soil water and salt distribution features during the grape growth season under field drip irrigation.

【Objective】 Distribution features of the soil water and salt under drip irrigation were studied to offer a reference for the adjustment and control of soil water and salt.【Method】 The soil water and salt distribution features were analyzed based on the field experiment in the grape farmland in Xinjiang.【Result】 The maximum soil water content under plastic mulching exists in the position about 30 cm from the dripper,and the water content decreases at the two sides of the position.The average soil salt content along horizontal direction is the highest at the position about 30-60 cm from the dripper.The salt concentration distribution feature is similar to the salt content,and the salt concentration is the highest at the soil surface.The soil remains dry for the irrigation period of 7.5 days.【Conclusion】 The irrigation technique parameters should be considered when the soil water and salt distribution features are adjusted.
