IRRIGATION SYSTEM AND METHOD USING WATER SHORTAGE DIAGNOSIS OF CROPS

摘要

The present invention relates to an irrigation system and method using water stress diagnosis of crops, and in particular, to a decision-making system and method for determining an appropriate irrigation timing and irrigation amount in connection with soil moisture information. The present invention comprises the steps of: generating measurement information by measuring meteorological information including at least one of temperature, humidity, solar radiation, or wind speed of the atmosphere in which the crop is located and the leaf temperature of the crop by a measuring unit; The index value of the moisture stress of the crop in the calculation unit by using the measurement information of a specific time period among the measurement information ( : Crop Water Stress Index) and effective soil moisture content ( Calculating ); And a reference value of the index value and a preset moisture stress in the control unit through the result of the calculation unit ( ), and the effective soil moisture content ( It provides an irrigation system and method using a water stress diagnosis of a crop comprising the step of determining irrigation by comparing with) and a threshold value of the Maximum Allowable Deficit (MAD) of the crop.
