摘要:
为防止农田表土流失、风蚀和犁底层加厚，为建制机械化的新型耕作制度，以德美亚1号为供试品种，研究了春季深松30和40 cm处理对土壤物理性状及玉米产量的影响。结果表明：春季深松对土壤紧实度、苗期土壤容重的降低和苗期土壤含水量的增加有明显作用,其中，春季深松40 cm处理效果较好；深松能够增加玉米产量，其中春季深松40 cm增产幅度最大，增产20.5%。
Abstract:
In order to set up new mechanical tillage system to prevent subsoil loss of farmland,wind erosion and plow pan thicken,the effect of spring subsoiling treatments on soil physical characteristics and maize yield were studied using Demeiya No.1.The result showed that there were obvious effects of spring subsoiling on soil compaction increasing,soil bulk density decreasing and soil water content increasing，the effect of spring subsoiling treatment with the depth of 40 cm treatment was better. Furthermore,subsoiling could increase maize yield.The spring subsoiling with the depth of 40 cm treatment could increase yield by 20.5%.
