Salinity Changes for Long-term Irrigation of Saline Water in Saline Soil in Xinjiang

The saline water irrigation is important pathway to improve the production potential in agriculture region of lack water resource. The cultivation was completely irrigated, the area threaten by salinization is one third of total cultivation, in Xinjiang. So, it will be important action to using the saline water in the saline soil for the improving of the agriculture production. The article be produced through long-term irrigation of saline water in saline soil, field experimentation of Fukang, C.A.S. it display that soil is intensively desalinization at 1 m depth for 2～5 g/L saline water irrigation in area of 3～5 m depth of the groundwater, the silt loam soil. The soil concentration is less through irrigating for 15 years with saline water. The anion/cation is 37 meq/kg at the moment, 0.248% salinity of weight ratio compare with soil in soil layer of 1m. The HCO~-_3 and K~++Na~+ is correspondingly more, respectively 4, 25 meq/kg of average in soil layer of 1m. Nevertheless, the soil salinity did not affect the crop cultivating and growth. So, It is feasible to irrigate the saline soil with saline water without drainage in Xinjiang.
