岩棉短程栽培模式中营养液对番茄生长及果实品质的影响

为实现设施番茄短程栽培过程中营养液的高效供给及标准化管理,寻求短程栽培模式中最优的营养液供给方式,在兼光型植物工厂条件下,研究了营养液电导率值（electric conductivity,EC值）、灌溉频率对番茄植株形态和果实品质的影响。试验以岩棉为栽培基质,3水平EC值为2、4和6 d S/m,3水平灌溉频率为1、3和5次/d,采用全因子试验设计方法,进行9组处理。采用综合评价方法获取最佳的营养液EC值和灌溉频率,并对植株形态和果实品质指标进行数理统计分析。结果表明：营养液EC值和灌溉频率影响植株的株高、茎粗、叶数、叶面积、叶形指数和根面比,同时也影响果实的平均质量、可溶性固形物（solub...

Summary:为实现设施番茄短程栽培过程中营养液的高效供给及标准化管理,寻求短程栽培模式中最优的营养液供给方式,在兼光型植物工厂条件下,研究了营养液电导率值（electric conductivity,EC值）、灌溉频率对番茄植株形态和果实品质的影响。试验以岩棉为栽培基质,3水平EC值为2、4和6 d S/m,3水平灌溉频率为1、3和5次/d,采用全因子试验设计方法,进行9组处理。采用综合评价方法获取最佳的营养液EC值和灌溉频率,并对植株形态和果实品质指标进行数理统计分析。结果表明：营养液EC值和灌溉频率影响植株的株高、茎粗、叶数、叶面积、叶形指数和根面比,同时也影响果实的平均质量、可溶性固形物（soluble solids content）和果形指数。其中EC值对平均果实质量影响显著（P〈0.05）,灌溉频率对叶面积和平均果实质量影响极显著（P〈0.01）;试验因素的交互作用对茎粗和果形指数影响极显著（P〈0.01）,对SSC影响显著（P〈0.05）。EC值为4 d S/m,灌溉频率为5次/d的营养液灌溉方式能兼顾植株发育和果实品质良好,该灌溉方式下SSC与平均果实质量呈极显著负相关（P〈0.01）。该研究可为设施短程栽培番茄优质高产提供指导依据。

In order to achieve high efficiency and standardized management of the nutrient supplement, tomatoes of short-term cultivation（Solanum lycopersicom L.; Brilliance 101） were grown in the greenhouse to explore a kind of nutrient solution irrigation condition to guarantee both yields and fruit quality. In this study, tomato plants were grown in an open rockwool system and the plants were irrigated with Yamazaki recipes nutrient solution to determine the responses of plant morphology, fruit weight and fruit quality to 2 factors including electrical conductivity（EC） and irrigation rates of nutrient solution from March to June. A suitable combination of EC and irrigation rates of nutrient solution was further obtained by using comprehensive evaluation method. The experiments were
