不同还田材料对废弃宅基地复垦土壤电导率的影响
|
摘要
为了探索不同还田材料在废弃宅基地土壤复垦中的熟化效果,研究了添加粉煤灰、有机肥和熟化剂三种还田材料后土壤电导率分布特征。结果表明:连续种植三季后施用有机肥处理耕作层土壤的保水性较其它两种处理有所提升,电导率下降较多,深层土壤电导率增大,能够减少次生盐渍化风险。不同还田材料的作物产量存在差异,与其它两种还田材料相比,施用有机肥能够较好的熟化废弃宅基地复垦土壤,促进冬小麦及玉米产量增长。
To explore the ripening effect of different returning materials to the soil reclamation in abandoned residential sites,the soil conductivity distribution after adding three kinds of returning materials,such as fly ash,organic fertilizer and curing agent,was studied.The results show that:(1)Compared with the other two treatments,the soil improved by organic fertilizer after three consecutive seasons has better water retention,the conductivity decreased more,and the conductivity of deep soil increased,which could reduce the risk of secondary salinization.(2)The crop yields of different returning materials are different.Compared with the other two kinds of returning materials,the application of organic fertilizer can better ripen the abandoned homestead to reclaim the soil and promote the growth of winter wheat and corn.
