气候变化可能会影响世界农业系统提供粮食的能力,纤维,为不断增长的世界人口提供燃料,特别是盐碱化土地的面积将会增加。然而,由于很少有植物物种(不到所有植物物种的1%)可以耐受盐渍土壤,我们认为,评估它们作为盐渍化土壤作物的潜力非常重要。我们分析了eHALOPH数据库中列出的植物的经济和潜在经济用途,包括最宽容的物种,盐生植物。对于经济价值的九个主要类别,截至2022年7月,在eHALOPH列出的所有物种中,我们共发现1365种使用;在盐生植物中,这一数字减少到918种.我们没有发现耐盐性较高的盐生植物和整个耐盐性植物之间的排名有任何明显差异,使用顺序是医学的,其次是牧草,传统医学,食物和饮料,燃料,薪材,和生物能源。虽然许多物种作为作物可能很重要,盐浓度对其用途的影响文献很少。增加盐浓度可以增加,减少,或者对不同物种中抗氧化剂的浓度没有影响,但是几乎没有证据表明盐度对潜在产量(浓度和生物量的乘积)的影响。盐度对牧草品质的影响也因物种而异,经常减少,但是对畜牧业生产的总体后果很少得到评估。耐盐植物在退化土地的生物修复中具有潜在用途(包括重新植被,植物修复,和NaCl的提取)以及生物燃料的来源,尽管使用盐水可持续灌溉耐盐作物必须极其谨慎。
Climate change is likely to affect the ability of world agricultural systems to provide food, fibre, and fuel for the growing world population, especially since the area of salinised land will increase. However, as few species of plants (less than 1% of all plant species) can tolerate saline soils, we believe it is important to evaluate their potential as crops for salinised soils. We have analysed the economic and potential economic uses of plants that are listed in the database eHALOPH, including the most tolerant species, halophytes. For nine main categories of economic value, we found a total of 1365 uses amongst all species listed in eHALOPH as of July 2022; this number reduced to 918 amongst halophytes. We did not find any obvious differences in rankings between the more tolerant halophytes and the whole group of salt-tolerant plants, where the order of use was medical, followed by forage, traditional medicine, food and drink, fuel, fuelwood, and bioenergy. While many species are potentially important as crops, the effects of salt concentration on their uses are much less well documented. Increasing salt concentration can increase, decrease, or have no effect on the concentration of antioxidants found in different species, but there is little evidence on the effect of salinity on potential yield (the product of concentration and biomass). The effect of salinity on forage quality again varies with species, often being reduced, but the overall consequences for livestock production have rarely been evaluated. Salt-tolerant plants have potential uses in the bioremediation of degraded land (including revegetation, phytoremediation, and extraction of NaCl) as well as sources of biofuels, although any use of saline water for the sustainable irrigation of salt-tolerant crops must be viewed with extreme caution.
