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。 According to the theories and methods of plant introduction and domestication, 191 forage grasses (86 families in 22 families) were collected from 1984 to 1989 successively from domestic and foreign countries. Local direct appraisal methods were used for light, medium and heavy d 72 varieties were screened out for selection of salinization soils on coastal saline soil in the west bank of Bohai Bay. The salt tolerance index of some herbage in different growth stages was further studied, and based on this, The corresponding adaptive cultivation techniques and pay for production. In 1989, Cangzhou had 48 million mu of artificial grassland. In the recent three years, the total grassland area of ​​the six provinces (autonomous regions) in the province and Shandong reached 1,503,000 mu, with a net increase of 40,498,000 yuan. Social benefits, ecological benefits are significant.
