摘要

为探讨不同修复模式对轻度砷污染农田的修复效果,2021 年 6-11 月利用田间小区试验开展轻度砷污染农田修复效果研究.种植萝卜、茄子、甘蓝、空心菜 4 种农作物,选用原位钝化技术、农艺调控措施和深耕 3 种常用的农田修复技术,进行了 26 组不同修复技术方案的试验.结果表明:在 26 组修复技术方案中,最优推荐的农田修复方案有 5 组,分别为:(1)"叶面肥+甘蓝"组农作物中砷含量去除率高达 84.6%;(2)"深耕+植空心菜"组土壤中有效砷含量去除率达 94.6%;(3)"叶面肥+植萝卜"组农作物中砷含量去除率高达 70.6%;(4)"土壤修复剂+叶面肥+甘蓝"组土壤中总砷含量去除率达 23.2%;(5)"鸡粪+空心菜"组土壤中有效砷含量去除率达 29.3%.研究表明,单一修复模式更适用于轻度砷污染的农田修复,其具有操作简单、修复费用低和修复效果好等优点,可为大面积开展轻度砷污染农田修复提供示范样板和技术方案.

Abstract

In order to explore the restoration effect of different restoration modes on mildly arsenic-contaminated farmland,a field plot experiment will be conducted from June to November 2021 to study the restoration effect of mildly arsenic-contaminated farmland.Using in-situ passivation technology,agronomic control measures and deep ploughing,26 groups of different restoration techniques were used to plant radish,eggplant,cabbage and water spinach.The results showed that:Among the 26 restoration schemes,there were 5 optimal recommended restoration schemes,as follows:(1)The removal rate of arsenic content in crops in the foliar fertilizer+cabbage group was as high as 84.6%;(2)The removal rate of effective arsenic content in the soil of deep tillage+water spinach group was 94.6%;(3)The removal rate of arsenic content in leaf fertilizer+radish group was as high as 70.6%;(4)The removal rate of total arsenic content in soil of soil repair agent+foliar fertilizer+cabbage group was 23.2%;(5)The removal rate of effective arsenic content in the soil of chicken manure+water spinach group was 29.3%.The study shows that the single restoration mode is more suitable for the restoration of mildly arsenic contaminated farmland,which has the advantages of simple operation,low restoration cost and good restoration effect,and can also provide a demonstration model and technical scheme for large-scale restoration of mildly arsenic contaminated farmland.
