以水稻品种宁粳53号为试验材料，研究了滴施CO₂水溶液对膜下滴灌水稻生育期、分蘖动态、株高、农艺性状和产量的影响。结果表明，与常规灌溉相比，滴施CO₂水溶液缩短膜下滴灌水稻生育期3 d，但显著提高株高（增幅为7.14%~8.19%）、SPAD值（增幅为10.56%~11.20%）、倒2节茎粗（增幅为6.14%~7.23%）、有效分蘖数（增幅为10.11%~10.34%）、有效穗数（增幅为1.33%~1.52%）和千粒重（增幅为1.64%~2.07%），最终提高产量10.39%~12.21%。

Using the rice variety Ninggeng 53 as material, this study investigated the effects of drip-applying CO₂ aqueous solution on the growth period, tillering dynamics, plant height, and agronomic traits of rice under film mulching drip irrigation. The results showed that, compared with conventional irrigation, drip-applying CO₂ aqueous solution shortened the growth period of rice under film mulching drip irrigation by 3 days but significantly increased its plant height (by 7.14%-8.19%), SPAD value (by 10.56%-11.20%), the diameter of the second node from the top (by 6.14%-7.23%), effective tiller number (by 10.11%-10.34%), effective panicle number (by 1.33%-1.52%), and 1000-grain weight (by 1.64%-2.07%), ultimately, increased the yield by 10.39%-12.21%.
