1. Research Concerns

Research works in the team focuses on the low yield and low input-output ratio problems in medium and low-yield fields , and the major problems in moderately and slightly contaminated farmland such as  the high activity of contaminants threatening the safety of agricultural products. In response to the urgent needs for improved agricultural quality and yield , high-quality and safe agricultural products and optimized ecological environment , the team conducts research on the occurrence and amelioration mechanisms of soil obstacle factors in medium and low-yield fields, biological-chemical processes and the control mechanisms of heavy metal availability in farmland, environmental friendly soil amendments  and construction of technical models and systematic solutions, providing strong scientific and technological support for improving farmland productivity andyield and ensuring farmland health and agro-environmental safety.
