RETRACTED: Study on Water and Salt Transport Features and Regulation for Salt-Effected Soil through Drip Irrigation under Film (Retracted Article)

The technology of drip irrigation under plastic film has advantages in the saline-alkalized land utilization. According to the soil water and salt transport feature with drip irrigation under plastic film, this paper analyzes salt distribution characteristic under drip irrigation in saline-alkalized land, reveals the salt transport rules in the cotton growth with different irrigation quota. The result shows that the irrigation quota is 5250m3/hm2, soil moisture content is in the range of 12.77 similar to 15.92% and salt content is in the range of 0.97 similar to 1.55%, which are good salt-water environment required by normal growth of cotton and have a higher water utilization efficiency. It has theoretical significance and application value on salt regulation and the establishment of irrigation system in saline-alkalized land. (C) 2011 Published by Elsevier Ltd.
