摘 要
随着农业现代化发展，传统肥料逐渐暴露出养分流失严重、利用率低等问题，新型肥料的研发与应用成为提升作物产量和改善土壤肥力的重要途径。本研究旨在探究新型肥料对作物生长及土壤肥力的影响，选取玉米为试验对象，在同一生态条件下设置新型肥料处理组和传统肥料对照组，通过田间试验，定期监测作物生长指标如株高、叶面积、干物质积累量等，并采集土样分析土壤有机质、全氮、速效磷、速效钾含量。结果表明，施用新型肥料的玉米各生育期生长指标均优于对照组，且新型肥料能显著提高土壤中有机质、全氮、速效磷、速效钾含量，降低土壤容重，增加土壤孔隙度。这主要归因于新型肥料具有缓释性，可减少养分流失，提高肥料利用率，同时其中含有的有益微生物能够促进土壤团聚体形成，增强土壤保水保肥能力，为新型肥料在农业生产中的推广应用提供了理论依据。

Effects Of New Fertilizers On Crop Growth And Soil Fertility
ABSTRACT
With the development of agricultural modernization, traditional fertilizers have increasingly exposed problems such as severe nutrient loss and low utilization rates. The research and application of new-type fertilizers have become a crucial approach to enhancing crop yield and improving soil fertility. This study aims to investigate the impact of new-type fertilizers on crop growth and soil fertility, selecting corn as the experimental subject. Under identical ecological conditions, a new-type fertilizer treatment group and a traditional fertilizer control group were established. Through field experiments, crop growth indicators such as plant height, leaf area, and dry matter accumulation were regularly monitored, and soil samples were collected to analyze the content of soil organic matter, total nitrogen, available phosphorus, and available potassium. The results indicate that the growth indicators of corn at various growth stages in the new-type fertilizer group were superior to those in the control group. Moreover, the new-type fertilizer significantly increased the content of soil organic matter, total nitrogen, available phosphorus, and available potassium, reduced soil bulk density, and increased soil porosity. This can primarily be attributed to the slow-release property of the new-type fertilizer, which reduces nutrient loss and enhances fertilizer utilization rate. Additionally, the beneficial microorganisms contained in the fertilizer promote the formation of soil aggregates, thereby strengthening the soil's water and nutrient retention capacity, providing theoretical evidence for the promotion and application of new-type fertilizers in agricultural production.
