Youbin Zheng PhD, MPhil, MAg, BAg.
Adjunct Professor
Research Scientist
Manager, Technical Operations for CESRF
Dept. of Environmental Biology, University of Guelph

Research Interests:

Light and crop production in greenhouse and controlled environment;

Irrigation (sensors and automation, balance water and oxygen in the root zone);

Plant nutrition, especially science and technology related to nutrient recirculation in hydroponic system and the application of low nutrient strategy in greenhouse production;

Disinfection technologies (e.g. electrolytically generated copper ion, ozone, chlorine etc) for water, nutrient solution and facilities in greenhouse and other controlled environment production systems (e.g. advanced life support system, nursery);

Root zone oxygenation (using modern technology to improve plant root zone oxygen environment and the responses of plant growth, physiology and diseases to root zone oxygenation);

Growth substrates development and evaluation (especially environmentally friendly growth substrates such as biodegradable and recyclable growth substrates) for greenhouse production;

Growth regulators [e.g. Ethephon (Ethrel)] application in floriculture production and their plant physiological effects;

CO2 enrichment and its effects on photosynthesis, respiration, transpiration, nutrient uptake and crop production;

New technology for growing medicinal crops (e.g. Echinacea and St. Johns Wort) in controlled environment (e.g. greenhouse);

Plant stress physiology, including plant response to O2, SO2, NOx, acid precipitation, water, heat, nutrient etc.

Organic Greenhouse Production;

Nursery Production.

I serve floriculture industry, greenhouse vegetable production industry, nursery industry and space advanced life support industry.
