摘　　要：为提高旱地胡麻旧膜再利用效率,寻求最佳的覆膜种植模式。以"陇亚10号"胡麻品种为供试材料,研究旧膜直播(T1)、旧膜覆土直播(T2)、旧膜秸秆双重覆盖播种(T3)、春天揭旧膜覆新膜播种(T4)、秋后整地覆新膜播种(T5)以及露地直播(CK)6种种植模式对胡麻经济效益的影响,运用熵权灰色关联耦合的方法对6种种植模式的经济效益进行综合评价。结果表明:与CK相比,T1的总产值、净产值和总利润分别提高了89%、99%、159%。从成本和投资综合来看,T1和T2的成本和投资指标整体较其他处理具有显著优势。覆膜种植模式下经济效益综合得分依次为:T1>T2>T4>T3>T5>CK,其中T1的经济效益显著优于其他模式,综合得分达到0.969,较T2、T3、T4、T5和CK显著提高90%、139%、131%、150%和174%。研究认为,旧膜直播(T1)模式不仅可以缓解废旧残膜造成的污染,而且具有显著的经济效益。In order to improve the efficiency of reusing old plastic film of oil flax in dryland,the best plastic film mulching planting pattern should be found.Taking"Longya No.10"oil flax variety as test material,the effects of six planting modes on economic benefits of oil flax were studied,including direct sowing with old film(T1),direct sowing with old film mulching soil(T2),double mulching sowing with old film straw(T3),sowing with new film mulching soil in spring(T4),sowing with new film mulching soil in autumn(T5)and direct sowing in open field(CK);the economic benefits of six planting patterns were evaluated by using the method of entropy weight grey correlation coupling.The results showed that total output value,net output value and total profit of T1 increased by 89%,99%and 159%,respectively,compared with CK.In terms of cost and investment,T1 and T2 showed significant advantages over other treatments in terms of cost and investment indicators.The comprehensive score of economic benefit of plastic film mulching was T1>T2>T4>T3>T5>CK,and the comprehensive score of T1 was 0.969,compared with T2,T3,T4,T5 and CK,it increased by 90%,139%,131%,150%and 174%,respectively.The results show that the model T1 not only alleviate the pollution caused by waste film,but also show significant economic benefits,so the model is worth to be popularized.
