CONSTANT DARKNESS TYPE CULTIVATION SYSTEM, HETEROTROPIC CULTIVATION CROP, AND CULTIVATION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a high-practicability plant cultivation process control method by a reactive engineering method, particularly to provide a cultivation system or the like capable of producing sprout vegetable and other heterotropic crop at a low cost and efficiently in a plant factory or the like.SOLUTION: A constant darkness type cultivation system 10 comprises a feedback control system 5 which measures a cultivation condition in a cultivation chamber 1 and performs control based on the condition, in which the cultivation chamber 1 comprises flow-down type sprinkling means 2 and one or a plurality of mounting parts 3 which mount an object to be cultivated thereon, the feedback control system 5 comprises measurement means and control means 8, the measurement means includes temperature measurement means 6 and gas concentration measurement means 7, and the control means 8 is designed to control a sprinkling condition of the sprinkling means 2 based on a measurement result. The gas concentration measurement means 7 measures at least oxygen concentration.SELECTED DRAWING: Figure 1
