Sowing should becarried outin the season when the soil moisture and temperature are suitable，such ason-demand sowing anddrillsowing.According to the characteristics of soybean andcorn varieties，reasonable planting patterns are adopted， including -row corn and -row soybean，2-row corn and 3-row soybean，and -row corn and 4-row soybean. Infield waterandfertilizermanagement，nitrogenfertilizeristhemainfertilizerandphosphatefertilizeristheauxiliary fertilizer.Chemicalcontrol method isadopted tocontrolthe growth ofcornandsoybean.Field weeding management is caried out bychemical weeding andartificial weeding.In viewofcommon root rot，corn borer，cottn bollworm，red fire antand other diseasesand pests of soybeanand corn，comprehensivecontrol measures such as physical control， biological pesticidecontroland ecological regulationareadopted.Adoptartificial or mechanical harvesting，timely harvest soybeans and corn，and timely drying，threshing， when the seed water content is less than 13% ， packaging storage.This paper provides areference forthe further popularizationof soybean and corn strip intercropping technology in the study area and related areas.
