摘要

PURPOSE:To obtain a multi-purpose control device in an orchard by house culture, usable as a system for liquid fertilization, chemical spraying and irrigating therein. CONSTITUTION:The objective multi-purpose control device is characterized by detachably installing a fan 3 on the top of a house 1 and providing a sprinkler 6 on the ground in the house. Since air temperature in the house can uniformly be kept by stirring of the fan 3 and temperature of the ground surface is prevented from becoming =0 deg.C, this device has effects capable of preventing an orchard from frost damage, and simultaneously, is useful for carrying out multi-purpose control of chemical spraying, irrigation, etc., and further its maintenance is facilitated by making the fan 3 freely attachable and detachable.
