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。
Thirteen cash crops were planted on plots with different salinities, and the crops suitable for planting salina soil with different salinities in this area were screened out. Cultivars of moderate chloride-sulphate saline soils with total salt content 2-4 g / kg in saline soils are cotton, sunflower oil, barley, Atriplex triangularis, beet, sudangrass, sedge, wild Begonia, Astragalus adsurgens, two orchid, alfalfa, Phyllostachys pubescens 12 kinds of cash crops and green manure forage; Among them, the strong salt resistance in the soil full salt content of 4 ~ 6 g / kg of heavy chloride - sulfate salt Five cultivated cashmere crops, green beans, Atriplex triangularis, sugar beet and sudangrass, and green manure and forage grass can be used for planting and planting, and good yields can be obtained.
