摘要 为探讨不同灌溉水质和水量对设施大棚番茄品质及产量的影响,采用主成分分析法对污水、再生水和清水3种不同水质和灌溉水量处理的番茄各项品质指标及产量进行综合评价。结果表明,所选取的4个主成分的累积贡献率达到89.70%。不同灌溉水质水量处理情况下,番茄果实中所含的维生素 C、硝酸盐、可溶性蛋白差异显著,可溶性糖、产量、灌溉水利用效率差异不显著。试验所采用的3种水质和水量条件下:数据经隶属函数处理的综合评价排名结果表明,水质为再生水、灌溉定额为360 mm 的灌溉条件最佳;2种数据平均排名结果表明,水质为再生水、灌溉定额为320 mm和360 mm 的处理较佳。 In order to investigate the effects of different irrigation water quality and quantity levels on the quality and yield of greenhouse tomatoes, principal component analysis was conducted for comprehensive evaluation of the effects of three types of water, which were sewage, reclaimed water, and fresh water, and the irrigation amount on the quality and yield of tomatoes. The results show that the accumulative contribution rate of four selected principal components was 89. 70% . There existed significant differences in vitamin C, nitrate, and soluble protein, but insignificant differences in soluble sugar, yield, and irrigation water utilization efficiency with different irrigation water quality and quantity treatments. Under the experimental conditions introduced above, the comprehensive evaluation results of the data handled by the membership function ranking showed that reclaimed water with an irrigation amount of 360 mm was the optimal irrigation condition. Average ranking results of the two sets of data showed that reclaimed water with irrigation amounts of 320 mm and 360 mm had a better effect.
