Abstract


Water development of natural resources indispensable for human survival , arid - semi-arid areas of sustainable development of agriculture is an important limiting factor with the rapid development of the national economy , the lack of water has become salty water resources development and utilization of irrigation water can effectively alleviate shortage. Drip irrigation is salt water using better irrigation , drip irrigation will be state-of-the-art water-saving irrigation technology - drip irrigation and mulching planting organic combine to form a water-saving but also development and utilization of saline and control of salinization the new method for saline areas of land and water resources development and utilization of new ideas and approaches . In this study, two saltwater drip irrigation under plastic film bottomed measured pits trials , positioning the observation field trials and pot experiments , discusses the film under salt water under drip irrigation , soil salinity distribution in time and space and accumulation characteristics ; analysis irrigation water salinity on cotton growth and yield of cotton the salt production function ; soil salinity affect on cotton germination rate and seedling growth ; summed up and in accordance with the relevant test data test soil salinity and its conductivity relationship.
