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2~4 g/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4~6 g/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。
In this study ,13 cash crops were planted in saline alkali soils with different salt content to evaluate their salt tolerant ability in Huanghuaihai plain of northern China .The results showed that:Gossypium spp.,Helianthus annuus L.,Hordeum vulgare L.,Atriplex triangularis,Beta vulgaris L.,Sorghum bicolor(L.)Moench ×S.sudanense (L.) Stapf,Sesbania cannabina 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 .
