Abstract: According to the theory and method that plant is introduced and domensti-cated,191 varieties of herbage were recommended and collected from herbage of the locality、other parts of the country and abroad from 1984 to 1989.Salt tole-rance of each variety in light、medium、strong saltinized soil were identificated using fied experimental method,72 varieties that adapted to different level salt tolerance soil on the west bank of the Bohai have been sieved.Furtherly,the salt tolerance indexes of different,growth period of some herbage were studied,and corresponding cultivative techniques were adoped in productive practice.The area of artificial pasture was 480 thousands mu in Cangzhou Region in 1989,the total planted area is 1503 thousands in Hebei、Shandong etc.six provin-ces.

摘要： 依据植物引种驯化的理论和方法,1984～1989年先后从国内外及当地引进、采集了191个牧草品补(22个科86个属);采用田间直接鉴定法进行了轻、中、重二种盐化程度的耐盐鉴定,筛选出72个品种可洪渤海湾西岸滨海盐渍土区不同盐化土壤上选择种植;进一步研究了部分牧草不同生育阶段的耐盐指标,以此为依据制定出相应的适应性栽培技术要点并付之以生产。1989年沧州地区已有人工草地48万亩,近三年本省及山东等六省(区)累计草地面积150.3万亩,净增产值4049.8万元。社会效益、生态效益非常显著。
