| 为探究设施蔬菜废弃物原位还田对土壤质量的影响，于2020—2022年设定番茄废弃物不还田（CK）、番茄废弃物原位还田1 a（TRR1）、番茄废弃物连续原位还田2 a（TRR2）、番茄废弃物连续原位还田3 a（TRR3）共4个处理，分析其对土壤理化性状及微生物数量的影响。结果表明：番茄废弃物还田使土壤pH值显著下降，土壤电导率和有机质含量随番茄废弃物的持续还田而显著增加。与对照相比，番茄废弃物持续原位还田处理使土壤速效磷和速效钾含量分别平均提高11.41%和31.40%；土壤脲酶活性变化不显著，TRR1、TRR2、TRR3处理土壤蔗糖酶活性和碱性磷酸酶活性较对照分别显著提高22.12%、30.46%、44.23%和17.90%、17.03%、11.08%。TRR3处理土壤细菌和放线菌数量显著高于其他处理，番茄成熟期TRR3处理分别比CK、TRR1和TRR2处理土壤细菌数量显著提高51.07%、61.21%和61.02%，土壤放线菌数量显著提高41.40%、20.61%和29.60%。土壤真菌数量和根结线虫数量随还田年限的增加而显著下降，其中TRR1、TRR2和TRR3处理根结线虫数量分别较CK降低30.14%、50.89%和81.70%。土壤质量指数分析结果表明，番茄废弃物还田使土壤质量从Ⅱ级提升为Ⅰ级，可作为管理蔬菜废弃物的环境友好型新策略。 |

| To investigate the effects of facility vegetable residues incorporation on soil quality, a total of four treatments were established from 2020 to 2022 including no tomato residues returning (CK), one\|year in\|situ tomato residues returning (TRR1), two\|year continuous in\|situ tomato residues returning (TRR2), and three\|year continuous in\|situ tomato residues returning (TRR3). The effects on soil physicochemical properties and microbial abundance were analyzed. The results demonstrated a significant decrease in soil pH, while there was a significant increase in soil electrical conductivity and organic matter content under continuous returning of tomato waste. Compared to CK, the average increase in available phosphorus and available potassium content in the soil was 11.41% and 31.40%, respectively, with the incorporation of tomato residues. In contrast to CK, there was no significant change in soil urease activity, sucrase activities were significantly enhanced by 22.12%, 30.46%, and 44.23%, and alkaline phosphatase activities were increased by 17.90%, 17.03%, and 11.08% in TRR1, TRR2, and TRR3, respectively. The number of soil bacteria and actinomyces in the TRR3 treatment was significantly higher than that in the other treatments. Specifically, compared to the control, TRR1, and TRR2 treatments, the number of soil bacteria increased by 51.07%, 61.21%, and 61.02% respectively in the TRR3 treatment. Similarly, the number of soil actinomyces also showed significant increases of 41.40%, 20.61%, and 29.60% respectively. The number of soil fungi and root\|knot nematodes exhibited a significant decrease with increasing years of tomato residues incorporation, while the application of TRR1, TRR2, and TRR3 resulted in reductions of 30.14%, 50.89%, and 81.70% respectively in the number of root\|knot nematodes compared to CK. The results of the analysis on the soil quality index indicated that the application of tomato residues in field management has led to an improvement from grade II to grade I, thereby presenting a novel and environmentally friendly approach for vegetable residue management. |
