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 .
