Abstract EN
Rice is the staple food for more than half of the world’s population, but selenium (Se) is low in many rice growing countries.
Water management model affects rice soil pH and Eh, and then affects the bioavailability of Se in soil.
A pot experiment was conducted to investigate the effects of water management on soil Se species, dynamics and selenium uptake by rice plants.
Sodium selenite was added to the soil so that the soil selenium content reached 0.5 mg kg1 to study the effects of 3 different water management modes on soil selenium uptake by rice plants.
These three modes are flood irrigation (F), aerobic irrigation (A) and alternate flood and aerobic irrigation (AFA).
The results showed that flooded irrigation treatment increased the soil soluble selenium concentration, and the selenium in soil solution mainly existed in the form of selenite and selenomethionine selenium oxide.
The content of selenium in grain was 2.44 and 1.84 times that of flooded irrigation treatment under A and AFA respectively.
The content of selenium in straw was 1.32 and 1.58 times that of flooded treatment under A and AFA respectively.
After rice grain enzyme hydrolysis, HPLC-ICP-MS analysis showed that Selenomethionine was the main selenium speciation in rice grains.
This study showed that aerobic flooded treatment is one of the most effective ways to increase selenium content in rice field
