摘要

In the plain irrigation districts in the Tarim Basin, Xinjiang where water resources are scarce, irrigation using brackish water is of great significance. The biggest problem with brackish water irrigation is salt accumulation in soil. The focus of concern of people is that, after 1-year application of brackish water irrigation, whether it is necessary to leach salt using winter irrigation or spring irrigation before sowing of the next year. This paper comprised data of easily dissolvable salt of 0∼60cm in soil which monitored from monitoring area S1 before and after spring irrigation in 2010 in Tarim Township of Yuli County, Xinjiang and salt tolerance indexes during germination, seedling and budding, flowering and boll generating, and boll opening periods of cotton (which are 7.1 g/kg,6.9g/kg,8.2g/kg and 9.2g/kg). The result shows that: in monitoring area S1, we can desalt leaching using spring irrigation once every other year to maintain the germination and growth requirements. The soil desalting ratio of monitoring area S1 before and after spring irrigation is 11.9%∼84.2%. Then we can conclude that the effectiveness of desalting leaching using spring irrigation in monitoring areas S1 were significant.
