摘　　要：开展污泥“变废为宝”的资源化利用,提高污泥资源化利用率,对防治城市生态环境污染,实现资源循环利用,促进社会绿色发展具有重要意义。研究基于华北平原典型小麦-玉米轮作体系长期田间定位试验,通过以不同用量的堆肥污泥部分替代化肥,探究2007-2022年期间施用堆肥污泥对作物产量和经济效益的影响,以期为污泥高效资源化利用提供理论支撑。结果表明,0.5W+0.5N和W+0.5N处理下作物的增产效果与N处理相当。4W+0.5N处理下作物的产量最高,试验期间小麦和玉米的平均经济产量分别为5 131.75 kg/hm^(2)和8 853.16 kg/hm^(2)。作物产量与污泥施用量呈显著正相关关系,相关系数可达0.85。不同污泥施用处理下,W+0.5N处理下的小麦和玉米的净收益达到最高,分别为19 453.22元/hm^(2)和18 848.43元/hm^(2)。The development of resource-oriented utilization of sludge,improving the resource utilization rate of sludge,is of great significance for preventing urban ecological environment pollution,achieving resource cycling and promoting green social development.This study is based on a long-term field positioning experiment of the typical wheat-corn rotation system in the North China Plain.By using different amounts of composted sludge to partially replace chemical fertilizer,the impact of using fertilized sludge on crop yield and economic benefits from 2007 to 2022 is explored,aiming to provide theoretical support for the efficient resource utilization of sludge.The results show that the effect of increasing composted sludge application between 0.5W+0.5N and W+0.5N treatments is equivalent to that of the N treatment.Under the 4W+0.5N treatment,the yield of crops is the highest,with average economic yields of 5131.75 kg/ha for wheat and 8853.16 kg/ha for corn during the experiment.The yield of crops shows a significant positive correlation with the application rate of sludge,with a correlation coefficient reaching O.85.Under different sludge application treatments,the net income of wheat and corn under the W+0.5N treatment reaches the highest,respectively 19453.22 YUAN/hm²and 18848.43 YUAN/hm².
