| Abstract: | 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%. |
