Title:
PLANT MOISTURE STRESS CONTROLLER AND METHOD FOR CONTROLLING PLANT MOISTURE STRESS
Document Type and Number:
Japanese Patent JP2022122289
Kind Code:
A
Abstract:
To provide a plant moisture stress controller and methods for controlling plant moisture stress that can avoid a facility environment, in which moisture stress increases to a plant, by using the secondary time derivative value of Humidity Deficit.SOLUTION: A plant moisture stress controller of the present invention has control means 30 and a secondary time derivative value calculating unit 40 for calculating the secondary time derivative value of Humidity Deficit measured by a Humidity Deficit measuring means 11, the humidity in a facility being controlled based on the secondary time derivative value of Humidity Deficit calculated by the secondary time derivative value calculating unit 40.SELECTED DRAWING: Figure 1
