摘　　要：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,并对粗纤维与Ca^(2+)含量进行了测定和比较。结果表明:种植于田园土中的4种牧草的Ca^(2+)含量大于种植于盐渍土中这个指标的含量,而粗纤维的含量并不具有上述特点,表现为大小不一。此研究结果,可以评价在不同土壤中牧草对Ca^(2+)吸收能力,并且对研究田园土与盐碱土对作物的影响有着实践意义。In this experiment, saline alkali grass （Puccinellia tenuiflora, Elymus dahuricus, Leymus chinensis, andal-falfa） were respectively planted in two kinds ofsoil, the coastal saline soil and garden soil, each repeated 3 times and the content of crude fiber and Ca^2＋ were determined and compared. The results showed that the Ca2＋ content of the four kinds of grass planted in the garden soil was larger than that in the saline soil, but the content of crude fiber did not have the above characteristics, instead,it hadthe performance of different sizes. According to the research results, the Ca^2＋ absorption capacity of grasscould be evaluated in the different soils, and it hada practical significanceto study the influence of rural land and saline soil on the crop.
