摘要:

【目的】探究灌溉水平和营养液浓度对椰糠袋培番茄生长特性、产量、品质及水肥利用效率的影响,明确椰糠袋培番茄适宜的营养液水肥管理模式,为设施椰糠袋培番茄水肥精准管理提供参考依据。【方法】设置灌溉下限和营养液浓度2个因素,灌溉下限设3个水平,椰糠袋持水量(FC)的60%(W1)、70%(W2)和80%(W3);营养液浓度设3个水平,霍格兰配方的0.8倍剂量(F1)、1.0倍剂量(F2)和1.2倍剂量(F3)。系统分析不同处理对番茄生长发育、光合特性、养分积累与利用、产量、品质、水分利用效率及肥料偏生产力的影响,结合熵权法、层次分析法(AHP)和TOPSIS法构建综合评价体系,优化灌溉和营养液管理指标。【结果】灌溉水平和营养液浓度均显著影响番茄株高、叶面积指数、地上部生物量、光合参数及氮磷钾养分积累。提高灌溉水平可显著促进植株生长与光合能力提升;在中高灌溉条件下适当提高营养液浓度有利于养分吸收和生物量积累。两年试验中,W3F3、W3F2和W2F2处理产量均处于较高水平,且处理间差异不显著(P>0.05),其中,W2F2处理在保持较高产量的同时,水分利用效率两年均达到最高,肥料偏生产力和综合品质表现较优。TOPSIS综合评价表明,W2F2处理两年的相对贴近度分别为0.7654和0.8177,排名第一。【结论】本试验条件下,灌溉下限为70%FC并配施1.0倍剂量霍格兰营养液的W2F2处理,能够较好协调番茄产量、品质和资源利用效率,可作为设施椰糠袋培番茄较优的营养液灌施管理模式。

Abstract:

【Objective】This study aimed to investigate the effects of irrigation levels and nutrient solution concentrations on the growth characteristics, yield, fruit quality, and water-fertilizer use efficiency of tomato growing in coir bag culture, and to determine an appropriate water and nutrient management mode for coir-grown tomatoes, so as to provide a reference for irrigation scheduling and nutrient solution application in coir bag culture. 【Method】Two factors, namely irrigation lower limit and nutrient solution concentration, were set in the experiment. The irrigation lower limit included three levels: 60% (W1), 70% (W2), and 80% (W3) of the water-holding capacity (FC) of the coir bag. The nutrient solution concentration also included three levels: 0.8-fold (F1), 1.0-fold (F2), and 1.2-fold (F3) of the Hoagland formula. The effects of different treatments on tomato growth and development, photosynthetic characteristics, nutrient accumulation and utilization, yield, fruit quality, water use efficiency and fertilizer partial factor productivity were systematically analyzed. In addition, a comprehensive evaluation system was established by integrating the entropy weight method, analytic hierarchy process (AHP), and TOPSIS method to optimize irrigation and nutrient solution management indicators. 【Result】Both irrigation level and nutrient solution concentration significantly affected tomato plant height, leaf area index, aboveground biomass, and photosynthetic parameters, as well as nitrogen, phosphorus and potassium accumulation. Increasing irrigation level significantly promoted plant growth and enhanced photosynthetic capacity. Under medium and high irrigation conditions, appropriately increasing nutrient solution concentration was beneficial to nutrient uptake and biomass accumulation. In the two-year experiment, W3F3, W3F2 and W2F2 all produced relatively high yields, with no significant differences among them (P>0.05). Among these treatments, W2F2 maintained a relatively high yield, while achieving the highest water use efficiency in both years, together with relatively good partial factor productivity of fertilizer and overall fruit quality. The TOPSIS comprehensive evaluation showed that the relative closeness coefficients of W2F2 were 0.7654 and 0.8177 in the two years, respectively, ranking first among all treatments. 【Conclusion】Under the experimental conditions, the W2F2 treatment, with an irrigation lower limit of 70% FC combined with a 1.0-fold Hoagland nutrient solution, could better coordinate tomato yield, fruit quality and resource use efficiency, and thus could be recommended as a relatively suitable fertigation management mode for greenhouse tomato growing in coir bag culture.
