在盐碱地上种植碱蓬和苜蓿的试验结果表明，种植碱蓬有明显的脱盐作用，０～６０ｃｍ深度土壤中的Ｎａ含量每年减少８３～１２８ｋｇ／亩．种植柽柳等８种盐生　和耐盐植物，一年后耕层土壤有机质，Ｎ、Ｐ、Ｋ养分，细菌，真菌数量增加，容重变小，渗透系数增大，土壤肥力状况得以改善．本文还提出８种有种植价值经济盐生植物，并对８种盐　生的耐植物的经济效益进行了比较． The results showed that the planting of Suaeda salsa had obvious desalination effect. The content of Na in the depth of 0 ~ 60cm was reduced by 83 ~ 128kg / mu per year. Planting tamarisk and other 8 kinds of salt and salt-tolerant plants, a year later tillage soil organic matter, N, P, K nutrients, bacteria, fungi increased, the bulk density becomes smaller, the permeability coefficient increases, soil fertility conditions can be improved. In this paper, eight kinds of economic halophytes with planting value were also proposed, and the economic benefits of eight kinds of salt-tolerant plants were compared.
