Land is considered as the life-sustaining platform for food and water. However, there are contaminants such as salt, heavy metal, and industrial waste that decrease land fertility, posing serious threat to sustainable agriculture. In recent years, novel crop varieties with improved tolerance against environmental contaminants have been developed, but most of them face severe yield penalty. Alternatively, naturally tolerant plants such as extremophiles can be screened for their potential as crops. These crops should be tolerant to various abiotic stresses, perform better under extreme conditions and produce higher biomass and yield. In view of this, the present review focuses on the effects of saline soil on plants and how a class of plants termed as “halophytes” can tolerate high levels of salt. The potential applications of halophytes in phytoremediation, desalination, secondary metabolite production, medicine, food, and saline agriculture have been discussed. A concept of saline agriculture has been proposed for rehabilitation of saline and degraded lands. In this context, a potential halophyte is cultivated in salt-contaminated soil for desalination. The harvested halophyte can have industrial value, and later on, rehabilitated soil can be utilized for agriculture purpose. Some success with halophyte cultivation has been demonstrated in environmentally degraded soils, and it is imperative that large-scale adoption of halophytes, as potential candidates, can be accorded top priority for rehabilitating contaminated soils, which can pave way for sustainable agriculture.

生物盐农业中的盐生植物:机理,利用和增值

土地被认为是维持食物和水的生命的平台。但是,盐,重金属和工业废料等污染物会降低土地肥力,对可持续农业构成严重威胁。近年来,已经开发出对环境污染物具有更好耐受性的新型农作物品种,但是其中大多数面临严重的单产下降。或者,可以筛选天然耐受的植物(如极端微生物)的农作物潜力。这些农作物应能耐受各种非生物胁迫,在极端条件下表现更好,并能产生更高的生物量和单产。有鉴于此,本综述着重于盐渍土壤对植物的影响,以及一类被称为“盐生植物”的植物如何能够耐受高水平的盐分。讨论了盐生植物在植物修复,脱盐,次生代谢产物,医药,食品和盐业中的潜在应用。已经提出了盐碱农业的概念来修复盐碱和退化的土地。在这种情况下,在盐污染的土壤中种植了潜在的盐生植物以进行淡化。收获的盐生植物可以具有工业价值,随后,修复后的土壤可以用于农业目的。在环境退化的土壤中已证明了盐生植物的种植取得了一些成功,当务之急是,大规模采用盐生植物作为潜在的候选者,应被视为修复受污染土壤的重中之重,这可以为可持续农业铺平道路。食品和盐农业。已经提出了盐碱农业的概念来修复盐碱和退化的土地。在这种情况下,在盐污染的土壤中种植了潜在的盐生植物以进行淡化。收获的盐生植物可以具有工业价值,随后,修复后的土壤可以用于农业目的。在环境退化的土壤中已证明了盐生植物的种植取得了一些成功,而且至关重要的是,大规模采用盐生植物作为潜在的候选植物,应被视为修复受污染土壤的重中之重,这可以为可持续农业铺平道路。食品和盐农业。已经提出了盐碱农业的概念来修复盐碱和退化的土地。在这种情况下,在盐污染的土壤中种植了潜在的盐生植物以进行淡化。收获的盐生植物可以具有工业价值,随后,修复后的土壤可以用于农业目的。在环境退化的土壤中已证明了盐生植物的种植取得了一些成功,而且至关重要的是,大规模采用盐生植物作为潜在的候选植物,应被视为修复受污染土壤的重中之重,这可以为可持续农业铺平道路。在盐污染的土壤中种植潜在的盐生植物进行脱盐处理。收获的盐生植物可以具有工业价值,随后,修复后的土壤可以用于农业目的。在环境退化的土壤中已证明了盐生植物的种植取得了一些成功,而且至关重要的是,大规模采用盐生植物作为潜在的候选植物,应被视为修复受污染土壤的重中之重,这可以为可持续农业铺平道路。在盐污染的土壤中种植潜在的盐生植物进行脱盐处理。收获的盐生植物可以具有工业价值,随后,修复后的土壤可以用于农业目的。在环境退化的土壤中已证明了盐生植物的种植取得了一些成功,而且至关重要的是,大规模采用盐生植物作为潜在的候选植物,应被视为修复受污染土壤的重中之重,这可以为可持续农业铺平道路。
