Using Yongyou 1540 and Chunyou 927 as test materials, we carried out a field trial in 2020, to explore the effects of oxygen-increasing pattern in paddy fields on rice root morph-physiological traits. The results showed that compared with CF treatment （continuous flooding）, OP treatment（topdressing calcium peroxide） significantly increased grain yield by 7.6%~8.7%; meanwhile, it improved rice root morphological and physiological traits, such as increased rice dry weight, root length density, root total absorbing surface area and active absorbing surface area at heading time and mid-grain filling period, and increased root oxidation activity, root bleeding rate and content of cytokinins （zeatin + zeatin riboside） in root bleeding during grain filling period. Meanwhile, OP significantly increased photosynthetic rate of the flag leaf and activities of sucrose synthase and adenosine diphosphate-glucose pyrophosphorylase in grains during grain filling period. The above results indicate that increasing oxygen in paddy fields can improve morphological and physiological traits of rice root, promote root-shoot growth, and increase grain yield.
Key words： rice; oxygen-increasing pattern; root morph-physiological traits; yield
