天津地处海河下游,有较丰富的尚未开发和利用的土地资源。全市929万亩耕地,其中盐碱地302万亩,亩产粮不足100公斤的低产田200万亩,尚有62.5万亩盐碱荒地。其中宁河县有连片荒地6万亩,低产田10万亩。为充分利用上述土地资源,天津市畜牧局组织有关科研单位和大专院校协作攻关,研究开发洼区草业,综合治理盐碱荒地及发展草牧经济的途径,经过4年努力已取得显著成绩。试验区自然条件和选择耐盐牧草试验区位于宁河西部大洼地带, Located in the lower reaches of Haihe River, Tianjin is rich in land resources that have not yet been developed and utilized. The city’s 929 mu of cultivated land, of which 302 mu of saline-alkali land, mu yield of less than 100 kilograms of low-yield fields 2 million mu, there are 625,000 mu of salt and alkali wasteland. Among them, Ninghe County has contiguous wasteland of 60,000 mu with a low yield of 100,000 mu. In order to make full use of the above land resources, Tianjin Animal Husbandry Bureau has organized significant scientific research units and tertiary institutions to make joint efforts to tackle this problem, to study and develop the depression grassland industry, comprehensively harness the saline-alkali wasteland and develop the grass-pastoral economy. After four years of hard work, remarkable achievements have been made . Experimental area of ​​natural conditions and selection of salt-tolerant grass test area is located in the western part of Ninghe depression,
