    摘要:

    采用基于客觀賦值法的熵權信息法與主觀賦值法相結(jié)合的綜合評價方法對不同加氧頻率處理溫室甜瓜綜合效益進行評價,，并對各加氧處理進行綜合效益排序,。結(jié)果表明,，2天1次的加氧頻率處理綜合效益最好，每天1次的次之,，不加氧處理的綜合效益優(yōu)于3天1次和每天2次處理,，溝灌處理的綜合效益最差。加氧灌溉均可以不同程度地提高溫室甜瓜的產(chǎn)量和品質(zhì),，但由于加氧處理增加了電費及滴灌設備及管件等資金投入,，致使一些加氧處理綜合效益降低。地下滴灌的溫室甜瓜綜合效益始終優(yōu)于溝灌,。

    Abstract:

    Evaluation of comprehensive benefit was conducted in greenhouse muskmelon under aeration irrigation by applying comprehensive evaluation method, which associated entropy information method based on objective weighting with subjective weighting method. Results showed that the comprehensive benefit order in every treatment was once per two days, once per day, none aeration, once per three days, twice per day, and furrow irrigation treatment. Aeration irrigation could improve yield and quality of greenhouse muskmelon differently, but the comprehensive benefit of some aeration treatments decreased because of the investment of electricity, drip facility, et al. The comprehensive benefit of greenhouse muskmelon in subsurface irrigation treatment was better than in furrow irrigation treatment. 
