Abstract: The aim of this study is to address the problem of soil film residue pollution caused by continuous mulching of maize in Hetao irrigated area.Two types of high-density cultivation were conducted in Hanggin Rear Banner,Inner Mongolia,for early-maturing and high-density maize varieties in 2018.The results showed that the treatment for KX9384 were clearly different in three ways from the control for Ximeng No.6 between film and non-film treatments.First,the yield of two plants per hole increased to 15.79%and 19.23%higher than the control.Second,the yield of two plants per hole had significant difference for Ximeng No.6 from yields with one plant per hole and three plants per hole.Third,the yields of 4∶4 interplanting and 2∶2 interplanting were significantly increased by 15.12%and 11.84%relative to the control treatment.The yield of 4∶4 interplanting was higher than 2∶2 intercropping,but not significantly.
