摘要

The mechanized large-ridge production technology of potato was summarized,including preparation before sowing,deep tillage and land preparation,deep application of chemical fertilizer,sowing,intertillage,disease and pest control,harvesting and other related contents.The comparative experimental study of large ridge and small ridge modes focused on the effects of ridge spacing on soil bulk density,temperature,water retention,crop growth and yield.The technology has the advantages of time saving,labor saving,seed saving,and fertilizer saving.It can significantly improve production efficiency,and is a high-yield and high-efficiency planting mode that increases potato yield.This model can increase yield by 370 kg/hm 2 and improve income by 160 yuan/hm 2.The results of this study have greatly promoted the promotion and application of mechanized largo-ridge potato planting technology.
