This study aimed to improve water use efficiency at side deep fertilization paddy fields and reduce the direct discharge of tailwater from upstream dry-farming into Erhai Lake. Field experiments were conducted Lake Basin in 2023 2024. In this study, paddies used as storage basins. Two managements set with three replicates: flooding irrigation controlled drainage (CKCD), water-saving (CCD). The rice growth indicators observed. results show that, 2023, compared CKCD, root volume, root-to-shoot ratio, stem node spacing, diameter, plant height, tiller number, leaf area index yield CCD increased by 13.6, 19.6, 12.1, 4.1, 9.4, 3.0, 21.9, 6.5%, respectively. For CCD, total amount decreased 27.3%, while productivity 46.7%. 2024, there similar trends 2023. However, number 11 1.5%, Additionally, 52.5%, 1.4 kg/m3. There regulars soil temperature its relationship other indicates Soil was generally higher than CKCD. It positively correlated but negatively volume. volume height dry matter accumulation. Overall, approach could promote indices growth, increase capacity storage, consumption further achieve savings yields.
