摘要： 在不同盐碱程度的地块上种植了13种经济作物,筛选出了适宜本地区不同盐渍度盐渍土种植的作物。能在盐渍土壤全盐含量2~4g⁄kg的中度氯化物-硫酸盐盐渍土上种植的有:棉花、油葵、大麦、三角叶滨藜、甜菜、高丹草、田菁、野豆子、沙打旺、二月兰、苜蓿、毛叶苕子12种经济作物和绿肥牧草;其中抗盐性较强的能在土壤全盐含量4~6g⁄kg的重度氯化物-硫酸盐盐渍土上种植的有田菁、野豆子、三角叶滨藜、甜菜、高丹草5种经济作物和绿肥牧草可种植利用,并获得较好的产量。

Abstract: In this study,13 cash crops were plantd in saline alkali soils with different salt content to evaluste their salt tolerant ability in Huanghuaihai plain of northern China.The result showed that:Gossypium spp.,Helianthus annuus L.,Hordeum vulgare L.,A triplex trainglaris,Beta vulgaris L.,Sorghum bicolor(L.) Moench×S.sudanense(L.) Stapf,Sesbania cannavina Pers.,G.soja.Sieb.et Zucc.,Orychophragmus violaceus(L.) ,Astragalus adsurgens Pall.,Medicago sativa L.,Vicia villosa Roth,these 12 crops could grow well in the soil with salt content 2-4 g/kg;Sesbania cannabina Pers., G.soja.Sieb.et Zucc.,Atriplex triangularis,Beta vulgaris L.,Sorghum bicolor(L.)Moench×S.sudanense(L.) Stapf could grow well in the soil with salt content 4-6 g/kg and got a better biomass.
