摘要:
对黑龙江省庆安、查哈阳、北安3个地区的有机种植基地与周边常规农田的土壤进行取样调查,旨在比较有机种植与常规种植2种种植方式对土壤主要理化性质以及土壤中重金属含量的不同影响。结果表明,与常规种植相比,施用有机肥的有机种植能明显提高土壤养分含量。其中,土壤有机质、总氮、总磷的含量最大提高6.97%~769%;而速效磷、速效钾等养分含量提高18.52%~53.5%;且施用有机肥,对土壤物理性质有明显的改良作用,能降低土壤容重,增加土壤中>0.25 mm水稳性团聚体含量。此外,有机种植对土壤中重金属的富集有一定的抑制作用,其中土壤中As、Hg、Cd、Cr含量降低了51.46%~82.99%。
