摘　　要：针对河套灌区玉米连年覆膜种植造成的地膜残留污染问题,2018年在杭锦后旗进行了早熟耐密玉米品种不覆膜1穴多株高密度栽培和中晚熟品种覆膜与早熟品种不覆膜1穴2株高密度栽培间种两种方式试验示范。试验1结果:KX9384 1穴2株、3株和1株处理较西蒙6号覆膜和不覆膜对照处理增产均达到极显著水平,增产幅度最高为1穴2株种植方式,分别为15.79%,19.23%;KX9384三种方式处理间,1穴2株比1穴3株和1穴1株增产极显著,1穴3株比1穴1株增产显著。试验2结果:两品种4∶4间种和2∶2间种较对照西蒙6号覆膜处理均极显著增产,分别增产15.12%和11.84%;4∶4间种比2∶2间种增产,但不显著。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.
