FROST PROTECTION MANAGEMENT SYSTEM FOR ORCHARD

摘要

PURPOSE: To obtain a water-sprinkling frost-protection system for orchard located far from human habitations and free from underground water vein and power supply. ;CONSTITUTION: An orchard having air-agitation fans is provided with a pump actuated with a light-sensor and a meteorological sensor. The pump is driven with a fan-driving generator by receiving the signal from the light-sensor or the temperature sensor to suck the water of the near river, pond or reservoir and the water is sprayed with a sprinkler to prevent the frost injury.;COPYRIGHT: (C)1994,JPO&Japio
