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。
對興電灌區油葵不同間作模式的效益進行瞭比較。結果錶明，油葵不同間作模式的土地噹量比（LER）均大于1，即均有間作優勢。其中油葵+馬鈴藷、油葵+豌豆、油葵+鬍痳、油葵+蠶豆模式的生產優勢度較高，穩定性較好，有較高的純收益和產投比，是興電灌區比較理想的模式。

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 .
