Overview
Background
Dr. Youhong Song is currently leading a research in crop/plant modelling and smart agriculture for sustainable crop production in School of Agricultural Sciences, Jiangxi Agricultural University.
Youhong is also supporting research in crop ecophysiology in Anhui Province, China where it is known as one significant food supplier province in the nation, aiming to sustain high maize/wheat productivity in facing the constraint of extensive abiotic stresses under climate change. Waterlogging during early canopy establishment, drought/heat stress during reproduction, lodging/interplant competition in maize season while in wheat season, late spring coldness, sprouting and lodging/interplant competition, are major concerns in achieving high crop production. To address the challenges, the knowledge from multidiscipline including crop physiology, agronomy, biology and crop modelling applies, extending from molecular to whole plant level. Projects are ongoing in relation to the above topics.
In particular, Youhong is engaged in bringing scientists together in collaborations for sustaining crop production and food security worldwide.
