- Intervention effect Aerated irrigation significantly increased soil oxygen content by 18.94~25.17% compared with non-aerated irrigation.
- Intervention effect Aerated irrigation significantly increased maize root biomass by 14.99~19.09% compared with non-aerated irrigation.
- Intervention effect Aerated irrigation significantly increased soil bacterial biomass by 35.10~45.59% compared with non-aerated irrigation.
- Intervention effect Aerated irrigation reduced soil water content by 5.33~12.71% compared with non-aerated irrigation.
- Intervention effect Aerated irrigation did not significantly change soil temperature.
- Intervention effect Aerated irrigation increased mean maize fruit yield by 7.16~20.51% compared with non-aerated irrigation.
- Intervention effect Aerated irrigation significantly increased maize stem thickness by 9.31~17.06% compared with non-aerated irrigation.
- Intervention effect Aerated irrigation significantly increased maize leaf area by 8.68~15.20% compared with non-aerated irrigation.
- Association Soil respiration rate was quadratically and negatively correlated with soil temperature, water content and soil oxygen under the two treatments.
- Association Soil respiration rate was positively correlated with root biomass and bacterial biomass through a power function under the two treatments.
- Observation In the PLSR model, soil temperature had a variable importance for projection (VIP) of 1.51.
- Observation In the PLSR model, soil oxygen content had a variable importance for projection (VIP) of 1.42.
- Observation In the PLSR model, root biomass had a variable importance for projection (VIP) of 1.40.
- Mechanism Aerated irrigation technology is interpreted to drive soil respiration rate by changing soil oxygen content and root biomass.
- Mechanism Improved soil aeration conditions and respiration under aerated irrigation appear to facilitate maize fruit yield improvement.
