Three imported industrial hemp varieties of Глесия（V₁）, Золотоношские15（V₂） and Гляна（V₃） were used as experiment, the growth characteristics, leaf area, dry matter weight and stem yield of industrial hemp under light and moderate saline-alkali conditions were studied. The results showed that plant height, stem diameter, root length, root volume, leaf area and dry matter weight of different varieties decreased with the increase of soil salinity and alkali concentration, light saline-alkali soil was higher than moderate saline-alkali soil, and the difference was significant. Under saline-alkali soil stress, the growth and development characteristics of V₁ were better than those of V₂ and V₃. The stem yield of V₁ under moderate saline-alkali stress was the highest, and V₂ decreased by 4.34,0.74 t/ha, respectively. Compared with that of V₂ and V₃, the difference was significant. The conclusion is that V₁ has the strongest salt and alkali resistance and V₂ has the worst.
