气候变化对半干旱地区作物微量元素利用率影响研究进展

Influence of Climate Change on Bioavailability of Micronutrients in Crops in Semiarid Area

气候变化对世界粮食增产和食品安全构成了威胁,尤其在半干旱地区。在此背景下,作物微量元素营养问题,及其在旱地土壤改良、粮食和食品安全方面的重要作用受到高度关注。本文分析了微量元素在粮食生产和食品安全上的重要地位,归纳了气候变化对作物微量元素利用影响的主要方面,初步梳理了半干旱地区开展相关研究的主要问题和方向,加深了对半干旱地区作物营养响应气候变化问题的理解。

Climatic changes will probably pose a threat to global food and nutrition security,especially in arid and semi-arid regions.In correlative reports of the available literatures,the bioavailability of micronutrients in crops was likely to have important and poorly understanding with climate change,which was of particular concern in soil improvement in drylands.The objective of this paper was to stimulate debate on a theme that bioavailability of micronutrients in foodstuff and food security had been either ignored or avoided in future research for its response to climatic change in semiarid area.In addition,there was a fairly good understanding of authors attempts to highlight potential consequences from experimental studies within process-based patterns of bioavailability of micronutrients in crops that should include interactions between climate and micronutrients accumulation.Furthermore,the authors gave some advices about prediction the bioavailability of micronutrients in crops or drylands soil improvement responses to future global climate change in arid and semi-arid area.
