摘　　要：对宁夏在小麦在不同盐分含量的土壤中生育情况研究结果表明，随土壤盐分含量的增加，小麦出苗时间推迟，出苗率下降，根系发育受到较大危害。表现为植株矮小，光合能力下降，营养生长期缩短，生殖生长提前，造成减产甚至绝产。The effect of different salt concontration on spring wheat growth were studied in this paper.Theresults indicate that as salt contents increasing ,spring wheat emergence is delayed , and emergence rateis slowed,furthermore,the root systems are harmed seriously, So that spring wheat is hindered from de-veloping further──individual plants are small and low, photosynthetic efficiency declines , vegetativestage is shortened,reproductive growth takes place in advance,and the wheat yield reduces badly andsometimes there is even no harvest at all.

关 键 词：土壤盐分 耐盐能力 春小麦 宁夏
