设施农业中水分调控与水分利用效率关系研究

Relations Between Moisture Regulation and Water Use Efficiency in Facility Agriculture

分析了中国设施农业发展现状及设施可控条件下作物生活因素全方位调控存在的问题。研究了作物水分利用效率与作物生产潜力、产量的关系。基于作物水分利用效率的生理生态机理 ,探讨了设施农业中节水灌溉对作物生活因素全方位调控的可行性。结果表明 ,设施农业环境中 ,在人工可控条件下的水分调控 。

The current situation of facility agriculture development in China and problems of crop growing factors control were analyzed . The relation between crop water use efficiency and crop productivity potential,crop yield were investigated. The feasibility of crop growing factors regulated and controlled by water saving irrigation in facility agriculture was discussed in terms of physio-ecological mechanism of crop water use efficiency. The results indicated that crop productivity potential and water-saving potential could be improved through the artificial moisture regulation and control in the facility agriculture environment.
