摘要
针对黄淮海２０００ｋｍ２内陆盐碱地，经２年时间，用盆栽实验方法进行研究，确定出五种豆科牧草耐盐临界值和极限值。其中保定苜蓿、猎人河苜蓿、红豆草这三种豆科牧草耐盐临界值为０．４％，极限值为０．５％。草木樨耐盐临界值为０．３％，极限值为０．４％。沙打旺耐盐临界值０．２％，极限值为０．３％。
After 2 years pot incubation test aimed at 2000km2 Huang Huai Sea inland saline-alkali region,thecritical and ultimate salt-tolerant value of the five leguminous grasses was determined.The critical valueof the three of them Baoding Medicago,Hunter river and Onobrychis viciaefolia was 0.4%,but their ultimatevalues were 0.5%. The critical value of Melilotus albus was 0.3%,the ultimate value was 0.4%. Thecritical value of Astragalus adsurgens was 0.2%.its ultimate value was 0.3%.
