摘　　要：对兴电灌区油葵不同间作模式的效益进行了比较。结果表明,油葵不同间作模式的土地当量比(LER)均大于1,即均有间作优势。其中油葵+马铃薯、油葵+豌豆、油葵+胡麻、油葵+蚕豆模式的生产优势度较高,稳定性较好,有较高的纯收益和产投比,是兴电灌区比较理想的模式。The benefit of oil sunflpwers interplanting models are compared . The results showed that land equivalent ratio （LER）are greater than 1 in different treatments,it is means has the intercropping advantage . The indicators,such as production advantage degree,stabilization,net benefits and VCR are better than contrast on oil sunflpwers＋potatoes and oil sunflpwers＋peas and oil sunflpwers＋flax and oil sunflpwers＋broad bean,all of those treatments are ideal modes in Xingdian Irrigation Area .
