摘　　要：长期采用表层耕作方式(10~15 cm)耕地容易导致土壤耕层变浅而形成明显的犁底层,降低土壤保墒、保肥能力,进而影响玉米根系的生长发育。为此,2023年在阜蒙县开展深旋耕改土增密技术研究,结果表明:种植密度3500株/667 m^(2)、深旋耕30~35 cm、增施有机肥的技术模式,可增加土壤耕层厚度、优化土壤结构和产量构成,有利于提高作物产量和水分利用效率,是辽西地区适宜的种植技术模式。Long-term use of surface tillage(10~15 cm)can easily lead to shallow soil layer and form obvious plow bottom,reduce soil moisture retention and fertilizer retention ability,and affect the growth and development of maize roots.Therefore,in 2023,deep rotary tillage was carried out in Fumeng County to improve soil densification technology research,the results show that:The planting density of 3500 plants/667 m^(2),deep rotation tillage of 30~35 cm and organic fertilizer application can increase soil topsoil thickness,optimize soil structure and yield composition,and then improve crop yield and water use efficiency,which is the appropriate planting technology model in western Liaoning.
