摘　　要：耕作层不仅影响耕地的质量水平还是农作物生长的重要基础。目前,国内建设占用耕地时耕作层没有得到有效的保护,一部分原因是耕作层保护的技术不完善,而表土剥离是保护耕作层的一个有效措施。因此,该文针对耕作层在剥离后储存期间的土壤进行培肥技术研究,通过设置3个试验小区,进行表土培肥试验,研究培肥后剥离土壤的有机质变化情况。研究结果显示:3个试验小区的4个处理中,土壤的有机质含量总体呈下降趋势,添加培肥均是有利于土壤有机质的积累;对于长时间的堆放,猪粪培肥效果最好;其次是秸秆培肥,秸秆加菌肥效果最差。对于丘陵和山地试验小区,猪粪培肥效果最好;在平原试验小区,秸秆和猪粪均有利于有机质的积累。The tillage layer not only affects the quality level of the cultivated land,but also is the important founda-tion for the growth of the crops.At present,the domestic construction of the occupation of cultivated land farming lay-er has not been protected effectively.Part of reasons is that magnetism protection technology is not perfect,and top-soil stripping is conservation tillage layer of a effective measures.Therefore,based on soil magnetism after strippingduring storage of soil fertilizer application technology research,by setting the three experimental plot,surface soil fer-tilizer experiment was carried out,the fertilizer after stripping changes of soil organic matter.The results showedthat：three experimental plots of four treatments,soil organic matter content was generally tended to de-crease,add fertilization were conducive to the accumulation of soil organic matter;for a long time stacking,pig manure fertilizer effect was the best,followed by cornstalk fertilization,straw and fertilizer effect of theworst.In hills and mountain plot experiment,pig manure fertilizer effect was best;in the plain plots,strawand pig manure were conducive to the accumulation of organic matter.
