外文摘要：Aiming to study the effects of long-term oxygenation and irrigation technology on soil fertility changes and maize yield under maize continuous cropping system in red loam soil, and explore the mechanism of maize yield increasement under this technology, which can provide theoretical basis for crop quality and yield increasement under aerated infiltration technology, relied on the 7 a (2017—2023) National Soil Quality Zhanjiang Observatory Experimental Station aerated infiltration experimental base, two treatments of traditional subsurface infiltration irrigation (CK) and aerated infiltration irrigation (01) were set up, and soil aeration, soil fertility, root growth, physiological characteristics and yield indexes under different treatments were determined. The results showed that the 01 treatment, which was implemented continuously for 7 a, improved soil aeration and soil fertility indexes compared with CK, and could significantly and very significantly increase soil oxygen content, soil respiration rate, soil bacterial biomass and soil urease activity, with increases of 2. 13% -22.89%, 1.86% -26.67%, 28.71% -49.51% and 13.59% -103.93%, respectively. On the basis of improving soil aeration and fertility, root length, root surface area and root dry weight were increased by 28. 08% -55. 69%, 24. 92% -73. 00% and 17. 16% -44. 86% (P ? 2025 Chinese Society of Agricultural Machinery.
