定西旱区地膜胡麻覆膜方式对比试验结果表明，两种覆膜方式下的胡麻出苗、成熟期均比露地（对照）提早，单株果数、千粒重等经济性状比对照增加。两种覆膜方式中，以平膜穴播产量较高，比对照增产９３．８％；垄膜沟播的经济效益较好，纯收益为３１２１．２元／ｈｍ２，稍高于平膜穴播，比对照收益提高１２３．１％，是经济、有效的覆膜栽培方式。
The results showed that the flax seedling under the two kinds of film mulching had earlier emergence and maturity than the open field (control), and the economic traits such as fruit number and thousand-grain weight per plant increased more than the control. In the two kinds of laminating methods, the filming yield was higher at flat film hole, yielding 93.8% more than that of the control film. The economical benefit of ridge filming and furrowing was good with the net income of 3121.2 yuan / hm2, slightly higher than that of flat filming, Revenue increased 123.1%, is an economical and effective film cultivation methods.
