摘要
耕地土壤环境质量与人类生活息息相关,健康的耕地土壤对人类健康至关重要。耕地安全利用技术是指通过叶面阻控、土壤钝化、水分调节、优化施肥、替代种植等技术手段使污染耕地上种植的农产品食用部位重金属不超标以达到安全利用的目的,这些技术手段虽然能够在一定程度上抑制重金属向农作物可食部位转移,但是土壤环境复杂,不同区域土壤物理性质也差别巨大。因此,不同的土壤环境需选择合适的安全利用技术,才能达到事半功倍的效果。基于此,本文对不同受污染耕地安全利用技术原理及适用场景进行了浅要的分析研究,希望为日后同行进行相关工作提供参考性意见。
The environmental quality of cultivated land soil is closely related to human life,and healthy arable land soil is crucial to human health.Cultivated land safe utilization technology refers to the use of foliar obstruction control,soil passivation,water regulation,optimization of fertilization,alternative planting and other technical means to make the polluted farmland planted on the edible parts of heavy metals do not exceed the standard to achieve the purpose of safe use,although these technical means can inhibit the transfer of heavy metals to the edible parts of crops to a certain extent,but the soil environment is complex,and the physical properties of soil in different regions are also very different.Therefore,different soil environments need to choose appropriate safe use technology in order to achieve the effect of doubling the results with half the effort.Based on this,this paper conducts a brief analysis and study on the technical principles and applicable scenarios of the safe utilization of different polluted arable land,hoping to provide reference opinions for future peers to carry out relevant work.
