摘要
以河南省永城市的矿区复垦农田为研究对象,分析4种不同复垦农作物(莲藕、芡实、水稻和玉米)对当地土壤质量与水质的影响,分析不同土地利用方式下的土壤养分指标,评估其土壤综合肥力指数,从环境角度比较旱生作物和水生作物2种不同复垦方式的环境生态效益,对当地采煤沉陷地复垦方式提出合理建议。结果表明,永城采煤塌陷各区域的水质均达到水田作物的灌溉水水质标准,土壤的氮素供应能力可能是限制水稻、莲藕以及芡实生长的环境因子。速效钾对水稻以及玉米的生长有限制作用。种植莲藕等水生植物促进当地复垦土地的保水保肥,固定土壤有效磷。永城市高潜水位矿区复垦土壤总体肥力水平中等偏上,其中选择水生作物进行复垦效果较为优良。
Taking the reclaimed farmland in the mining area of Yongcheng,Henan Province as the research object,the effects of four different reclamation crops(lotus root,chia,rice and maize)on local soil quality and water quality were analyzed,the soil nutrient indicators under different land use patterns were analyzed,the comprehensive soil fertility index was evaluated,the environmental ecological benefits of two different reclamation methods of dry crops and aquatic crops were compared from the environmental perspectives,and reasonable suggestions were put forward for the reclamation methods of local coal mining subsidence.The results showed that the water quality of the areas of Yongcheng coal mining collapse reached the irrigation water quality standard of paddy crops,and the nitrogen supply capacity of the soil may be an environmental factor restricting the growth of rice,lotus root and gorgon fruit.Available potassium has a limiting effect on the growth of rice and maize.Planting aquatic plants such as lotus root promotes water and fertilizer retention in local reclaimed land and fixes soil available phosphorus.The overall fertility level of reclaimed soil in the high diving position mining area of Yongcheng City was moderately high,and the reclamation effect of aquatic crops was relatively good.
