PHOTOSYNTHESIS PROMOTION DEVICE OF PLANT AND CONTROL METHOD THEREOF

摘要

PURPOSE: A photosynthesis facilitating device of plants is provided to supply carbon dioxide of a suitable amount to the plants cultivated at a plantation at the necessary time. CONSTITUTION: A storage tank(110) is installed at a plantation in which plants are cultivated and is filled with carbon dioxide inside. Carbon dioxide is supplied from a storage tank to a supply tube(130). A discharge outlet(140) is formed to penetrate to a supply tube so that carbon dioxide supplied to a supply tube is discharged to outside. Multiple discharge outlet are arranged in a longitudinal direction of a supply tube with separating at a constant interval. Multiple discharge outlet are opened in consecutive order. Carbon dioxide concentration detecting means(150) measures the concentration of carbon dioxide in a plantation. A sprinkler(170) supplies water to plants with arranging at a constant interval in a plantation.
