Résumé partiel
Due to the special geographical location and climatic conditions,the southern margin of Junggar Basin is short of water resources and the ecological environment is extremely fragile.Haloxylon ammodendron,as a typical desert plant in the region,has good functions of sand fixation and ecological conservation.The proportion of agricultural water in the middle and upper reaches of the southern margin of Junggar basin is too large,so it is difficult to guarantee the ecological water resources in the lower reaches.Therefore,the development and utilization of local saline water resources to irrigate desert plants provides a new way for ecological environment construction.In this experiment,the typical desert plant Haloxylon ammodendron was selected as the research object,and the pit test was carried out in the Key Laboratory of Modern Water-saving Irrigation Corps.Five irrigation salinity levels were set as A:1 g L-1,B:6 g L-1,C:9 g L-1,D:12 g L-1,E:15 g L-1.The effects of drip irrigation with different mineralized water sources on soil water content,soil salt content,ion distribution and soil hydrochemical types of Haloxylon ammodendron were studied.The contents of chlorophyll,proline,malondialdehyde,soluble protein and soluble sugar,plant height,branch length,stem diameter and crown width of Haloxylon ammodendron were determined.Based on the above
