摘　　要：实验将耐盐碱牧草(碱茅、披碱草、羊草、紫花苜蓿)分别种植在滨海盐土、田园土壤两种土壤中,每种牧草3次重复,并对粗蛋白与粗脂肪这两种营养成分进行了测定和比较。结果表明:在测定的牧草两种成份中,种植于田园土中的四种牧草的粗蛋白,粗脂肪大于种植于盐渍土中这两个指标的含量。根据研究结果,综合评价了盐碱土对于四种牧草的主要营养成分的影响,通过对两个指标的比较来评价了四种牧草的耐盐碱能力,该结果对盐碱地的改良有实践和指导意义。In this experiment,saline alkali forage(Puccinellia tenuiflora,Elymus dahuricus,Leymus chinensis,alfalfa)were planted respectively in the coastal saline soil and garden soil,where each grass was repeated 3times and two nutrients,crude protein and crude fat,were determined and compared.Result showed that:as for the two components of the forage,coarse prote and coarse fat of the forage planted in the garden soil were more than those in the saline soil.According to the result of the study,comprehensive evaluation of the effect of saline alkali soil for the main nutritional components of four kinds of forage grass was conducted.By comparison of the two indexes,we evaluated the four forage's saline-alkali stress,which would have practical and guiding significance to the improvement of saline alkali soil.
