    • 摘要: 为有效提高农业废弃物的利用率,将堆肥、秸秆等农业废弃物和黏土等拌制成一种抗旱促根的基质,研究水肥耦合效应对"爱吉3041"供试基质栽培番茄的株高、茎粗、产量、品质、水分利用效率(Water Use Efficiency,WUE)及肥料偏生产力(Partial Factor Productivity of Fertilizer,PFP)的影响,以当地实际生产水肥施用量作为对照组CK,设置9组基质水肥耦合处理,3组滴灌水量W1(100%ET0,ET0为参考作物蒸发蒸腾量)、W2(80%ET0)、W3(60%ET0)和3组施肥(N-P2O5-K2O)水平F1(240-115-137 kg/hm2)、F2(180-88-121.2 kg/hm2)、F3(112-50-82 kg/hm2)共10组耦合处理,建立番茄产量、WUE、PFP及果实综合品质的多目标优化模型,采用遗传算法多目标优化法寻找模型的Pareto最优解。结果表明:与CK相比,基质对番茄的株高、茎粗、根系发育、产量、品质、WUE和PFP等影响显著,根质量、根长、根表面积分别增加了36.0%、6.27%、3.94%,可有效改善果蔬品质;利用VIKOR法对各处理的果实品质进行综合评价,基质栽培番茄果实风味品质和产量显著提高,W3F1处理下番茄风味品质及产量最佳,利益比率值最小;基于遗传算法多目标优化法表明基质栽培番茄的最佳灌溉施肥处理为W3F2,该处理下的最优产量为25.85 t/hm2,最优水分利用效率为13.77%,最优糖酸比为9.51,利益比率为0.357。研究可为农业废弃物高效利用及高品质果蔬的水肥科学管理提供理论依据。

       

      Abstract: Abstract: A large amount of agricultural waste has been generated each year in China, particularly with about 900 million tons of crop straw and 260 million tons of tailings. The proper disposal can greatly contribute to the high utilization of agricultural waste in the environmental ecosystems, and the less surface pollution in farmland. However, the current resource utilization of agricultural waste has posed a great challenge, such as straw and livestock manure. It is a high demand to find a rational way for the sustainable production of agricultural waste. In this study, a drought-resistant and root-promoting substrate culture was fabricated to mix the compost and crop straw with clay, in order to improve the utilization rate of agricultural waste. A systematic investigation was made to clarify the effect of water-fertilizer coupling on the growth, yield, quality, water use efficiency (WUE), and partial factor productivity of fertilizer (PFP). Taking the tomatoes were grown on "Aegis 3041" as a test crop, nine water-fertilizer coupling treatments were set using substrate cultures, i.e., three groups of drip irrigation water W1, W2, and W3 (high water: 100% ET0, medium water: 80% ET0, low water: 60% ET0, where ET0 was the reference crop evapotranspiration), while three groups of fertilizer F1, F2 and F3 (N-P2O5-K2O) levels (high fertilizer: 240-115-137 kg/hm2, medium fertilizer: 180-88-121.2 kg/hm2, low fertilizer: 112-50-82 kg/hm2), and the CK was used as a control group with reference to the actual local production of water and fertilizer. A total of 10 coupled treatments were developed to comprehensively evaluate the tomato yield, WUE, PFP, and overall fruit quality. A genetic algorithm (GE) multi-objective optimization model was also established to optimize the evaluation. The results showed that the plant height of tomatoes in the substrate culture presented a trend of increasing and then decreasing, with the increase of irrigation amount during each fertility period. The mass, surface area, and length of root increased by 36.9%, 4.0%, and 6.3%, respectively, under the same fertilizer application conditions, compared with CK. Correspondingly, the substrate culture was effectively improved the plant height, stem thickness, root development, yield, quality, WUE, and PFP. The VIKOR method was used to comprehensively evaluate the fruit quality of each treatment. The fruit flavor quality and yield of tomatoes cultivated in substrate were significantly improved. The tomato flavor quality and yield were the best under the W3F1 treatment, and the benefit ratio was the smallest. The GE multi-objective optimization demonstrated that the best irrigation-fertilization treatment was W3F2 for the substrate culture, with the highest yield of 25.85 t/hm2, a lowest WUE of 13.77%, an optimum sugar to acid ratio of 9.51, and a benefit ratio of 0.357. Consequently, the substrate culture cultivation technology can be widely expected to save the water and fertilizer for the higher productivity and quality of fruits and vegetables, there by efficiently improving the utilization rate of agricultural waste resources. The effective way can be served to dispose of the agricultural non-point source pollution for the fewer carbon emissions in the sustainable crop production. The photovoltaic plus brick development can greatly contribute to transforming facility agriculture into natural agriculture in the future, such as the rich land resources in northwest China. This finding can also provide theoretical support to the efficient use of agricultural waste, as well as the rational management of water and fertilizer for the high-quality fruits and vegetables in modern agriculture.
