Abstract

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.
