随着农业集约化发展，化肥过量施用导致土壤板结、氮磷淋溶损失等问题日益突出。本文以辽宁省朝阳县腰儿营子村作为试验点，选用A677玉米品种，设置40%、50%、60%、70%、100%五个有机罐肥替代化肥梯度，配套总养分≥12%、有机质≥40%的有机罐肥与控释期60天的三宁牌控释肥，采用随机区组设计，每处理3次重复，系统评估不同替代比例对玉米农艺性状、产量构成、籽粒品质及土壤理化性质的影响。结果表明：70%、100%替代处理平均亩产量分别达1068.07kg、1075.09kg,较对照增产12.52%、13.26%,差异达显著水平，即P<0.05,单穗标准干重最高达0.298kg,籽粒含水量降低1.2%～3.4%,干物质积累量提升9.8%～15.6%。研究证实，有机肥与控释肥协同施用可通过优化养分释放节律、改善土壤团聚体结构、提高微生物生物量碳氮含量，实现玉米稳产增产与品质提升的双重目标，为辽西地区化肥减量增效提供了一定的技术支持。

With the development of agricultural intensification, excessive use of chemical fertilizers has led to increasingly prominent problems such as soil compaction and nitrogen and phosphorus leaching losses. This article takes Yaoeryingzi Village, Chaoyang County, Liaoning Province as the experimental site, selects A677 corn variety, and sets up five organic tank fertilizers to replace chemical fertilizer gradients of 40%, 50%, 60%, 70%, and 100%. The organic tank fertilizers with total nutrients ≥ 12% and organic matter ≥ 40% are matched with Sanning brand controlled-release fertilizers with a controlled release period of 60 days. Randomized block design is adopted, with 3 replicates per treatment, to systematically evaluate the effects of different substitution ratios on maize agronomic traits, yield composition, grain quality, and soil physicochemical properties. The results showed that the average yield per mu of the 70% and 100% substitution treatments reached 1068.07kg and 1075.09kg, respectively, with an increase of 12.52% and 13.26% compared to the control. The difference was significant, with P<0.05. The highest standard dry weight per spike was 0.298kg, the grain moisture content decreased by 1.2% to 3.4%, and the dry matter accumulation increased by 9.8% to 15.6%. This study confirms that the synergistic application of organic fertilizers and controlled-release fertilizers can achieve the dual goals of stable and increased corn production and quality improvement by optimizing nutrient release rhythms, improving soil aggregate structure, and increasing microbial biomass carbon and nitrogen content. This provides technical support for reducing chemical fertilizer input and increasing its use efficiency in the western Liaoning region.
