The recent over production of municipal solid waste (MSW) poses a significant threat to both the ecosystem and human health. Utilizing MSW for agricultural purposes has emerged as a promising strategy to reduce solid waste disposal while simultaneously increasing soil fertility. To explore this potential solution further, an experiment was designed to assess the impact of varying concentrations of MSW (25%, 50%, and 75%) on the proximate composition of 15 different vegetable species. The experiment, conducted between 2018 and 2019, involved treating soil with different levels of solid waste and analyzing the proximate components, such as crude protein, dry matter, crude fiber, crude fat, and moisture content, in the 15 selected crops. The results indicate that the application of 25% MSW significantly increased the levels of crude protein, crude fiber, dry matter, and fat in Spinacia oleracea, Solanum tuberosum, Solanum melongena, and Abelmoschus esculentus. Conversely, the addition of 75% MSW notably elevated the moisture and ash content in Cucumis sativus. Correlation and scatter matrix analyses were conducted to elucidate the relationships between the protein, fiber, dry matter, ash, and fat contents. Principal component analysis and clustering confirmed the substantial impact of Treatment_1 (25% MSW) and Treatment_3 (75% MSW) on the proximate composition of the aforementioned vegetables, leading to their categorization into distinct groups. Our study highlights the efficacy of using 25% MSW to enhance the proximate composition and nutritional value of vegetables. Nonetheless, further research is warranted to investigate the mineral, antioxidant, vitamin, and heavy metal contents in the soil over an extended period of MSW application.
最近，城市固体废物（MSW）的过度产生对生态系统和人类健康构成了重大威胁。将 MSW 用于农业目的已成为一种有前途的策略，可以减少固体废物的处理，同时提高土壤肥力。为了进一步探索这一潜在解决方案，设计了一项实验，以评估不同浓度的 MSW（25%、50%和 75%）对 15 种不同蔬菜品种的近似成分的影响。该实验于 2018 年至 2019 年进行，涉及用不同水平的固体废物处理土壤，并分析 15 种选定作物的近似成分，如粗蛋白、干物质、粗纤维、粗脂肪和水分含量。结果表明，应用 25%的 MSW 显著增加了 Spinacia oleracea、Solanum tuberosum、Solanum melongena 和 Abelmoschus esculentus 中的粗蛋白、粗纤维、干物质和脂肪含量。相反，添加 75%的 MSW 显著增加了 Cucumis sativus 的水分和灰分含量。进行了相关性和散点矩阵分析，以阐明蛋白质、纤维、干物质、灰分和脂肪含量之间的关系。主成分分析和聚类证实了处理 1（25%的 MSW）和处理 3（75%的 MSW）对上述蔬菜近似成分的重大影响，导致它们分为不同的组。我们的研究强调了使用 25%的 MSW 来提高蔬菜的近似成分和营养价值的效果。然而，需要进一步研究以调查在较长时间内应用 MSW 后土壤中的矿物质、抗氧化剂、维生素和重金属含量。
