摘  要:
采用基于客观赋值法的熵权信息法与主观赋值法相结合的综合评价方法对不同加氧频率处理温室甜瓜综合效益进行评价,并对各加氧处理进行综合效益排序。结果表明,2天1次的加氧频率处理综合效益最好,每天1次的次之,不加氧处理的综合效益优于3天1次和每天2次处理,沟灌处理的综合效益最差。加氧灌溉均可以不同程度地提高温室甜瓜的产量和品质,但由于加氧处理增加了电费及滴灌设备及管件等资金投入,致使一些加氧处理综合效益降低。地下滴灌的温室甜瓜综合效益始终优于沟灌。

摘  要:
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.
