Development of SWAT-PADDY for Simulating Lowland Paddy Fields

open access: yesSustainability, 2016
The consumption of rice, which recently increases globally, leads to requirement for planning sustainable water management for paddy cultivation. In this research, SWAT model was modified to evaluate sustainability of paddy cultivation. Modifications to simulate paddy cultivation are 1) to equip with a new water balance model of impounded fields, 2) to

Spatial distribution of plant-available silicon and its controlling factors in paddy fields of China

open access: yes, 2021
Silicon (Si) is beneficial for rice health and production by alleviating various biotic and abiotic stresses. However, the continual export of grain off-farm may result in Si deficiency for rice plants.

Effect of straw return on soil respiration and NEE of paddy fields under water-saving irrigation. [PDF]

open access: yesPLoS ONE, 2018
Straw return (SR) and rice water-saving irrigation (WSI) affect the greenhouse gas emission of paddy fields. However, studies on CO2 exchange between paddy fields and the atmosphere with joint regulation of SR and WSI are few.
