本文主要概括了甘肃草原生态研究所的有关研究结果认为：碱茅（Ｐｕｃｃｉｎｅｌｌｉａｔｅｎｕｉｆｌｏｒａ）种子萌动（相对发芽率达５０％）时的硫酸盐盐渍度２．５～２．７ｇ／１００ｍｌ，ＮａＣｌ为１．６～１．８ｇ／１００ｍｌ，Ｎａ２ＣＯ３为０．９～１．２ｇ／１００ｍｌ。碱茅的抗盐机制为：（１）对Ｎａ＋、Ｋ＋的选择性吸收与运输；（２）渗透调节适应；（３）合成积累有机物质的保护作用等多途径。小花碱茅叶片无盐腺组织，纠正了将其划为泌盐植物的观点。在灌溉条件下建植的Ｐ．ｔｅｎｕｉｆｌｏｒａ－Ｐ．ｃｈｉｎａｍｐｏｅｎｓｉｓ草地，有改良耕层土壤的作用，土壤盐分的下移灌水起主导作用；减少返积盐（向上返盐），草起主要作用。
This paper mainly summarizes the results of Gansu Institute of Grassland Ecology research concluded that: when the seed germination (relative germination rate of 50%) of Puccinellius uiflora seedling 2.5 ~ 2.7g / 100ml of salinity, NaCl is 1 .6 ~ 1.8g / 100ml, Na2CO3 is 0.9 ~ 1.2g / 100ml. Alkali Mao’s salt resistance mechanisms are as follows: (1) Na +, K + selective absorption and transport; (2) osmotic adjustment; (3) the accumulation of organic compounds and other protective ways. Sapwood leaves without salt gland tissue, corrected its point of view classified as salt-producing plants. P. planted under irrigation conditions. tenuiflora-P. chinampoensis grassland, there is the role of improved topsoil, soil salinity downward drip play a leading role; reduce the return salt (upward return salt), grass play a major role.
