摘　　要：通过种植碱茅草改良盐渍土壤生态环境进而种植农作物具有明显的效益。地下水位较低且排水良好的盐渍地种植碱茅草3年后再种植甜菜、春小麦、胡麻及糜子等作物其产量、净收益及投产比都达到或接近了当地中产田的水平。土壤盐分仍是影响作物生长的主要因素,需加强管理及进一步研究。Puccinellia chinampoensis planted in saline soil has significant effect of improving the quality of the soil, benefiting the later crop production on the land. After three years of plantation of the species the saline land with a relatively low water table and well drained was used for sugar beet, spring wheat, linseed and millet production. The yield of these crops, the net profit and the input-output ratio of these production activities reached the level of average cropland in the region where the experiment site was located. The salt content in the soil remains as a major factor affecting after crops and this requires more careful management and further studies.
