酸土修复材料在漠沙酸化坡耕地玉米产能提升中的示范应用

Demonstration Application of Acid Soil Remediation Materials for Improving Maize Productivity on Acidified Sloping Farmland in Mosa Town

摘要: 为探明酸土修复材料对滇南酸化坡耕地玉米产能的提升效果，2025年在新平彝族傣族自治县漠沙镇胜利村开展田间示范试验。以先正达901为供试品种，设常规种植(CK)、商品酸土调理剂(T1)和自主研发酸土修复材料(T2)3个处理，比较各处理对土壤理化性状、玉米农艺性状及产量的影响。结果表明：T2处理折亩产581.82 kg，较CK增产5.72%，土壤pH由4.62提升至4.94，速效磷含量显著提高；T1处理折亩产497.17 kg，较CK减产9.67%，土壤改良效果亦不理想。自主研发酸土修复材料在本地区酸化坡耕地上具有较好的适应性和增产效果，具有推广应用价值。

Abstract: To investigate the effects of acid soil remediation materials on improving maize productivity in acidified sloping farmland in southern Yunnan, a field demonstration experiment was conducted in Shengli Village, Mosa Town, Xinping Yi and Dai Autonomous County, in 2025. The maize variety Syngenta 901 was used as the test material. Three treatments were established: conventional cultivation (CK), a commercial acid soil conditioner (T1), and a self-developed acid soil remediation material (T2). The effects of different treatments on soil physicochemical properties, maize agronomic traits, and yield were compared. The results showed that the yield of T2 reached 581.82 kg per mu, representing an increase of 5.72% compared with CK. Soil pH increased from 4.62 to 4.94, and available phosphorus content was significantly improved. In contrast, the yield of T1 was 497.17 kg per mu, which was 9.67% lower than that of CK, and its soil improvement effect was also unsatisfactory. The self-developed acid soil remediation material showed good adaptability and yield-increasing effects on acidified sloping farmland in this region, indicating its potential for further extension and application.
