TEMPERATURE CONTROL FOR WATER IN RICE PADDY

摘要

PROBLEM TO BE SOLVED: To provide a water temperature controller for rice paddy that can prevent the cool damage caused by water temperature. SOLUTION: The water level setter 30 is set to a proper level suitable for growth of rice plants and weather conditions. The water-level and water- temperature controller 40 calculates the amount of water to be fed for attaining the water level set by the water level setter 30 and calculate the water temperature after the water feeding based on the water temperature of the water source to be fed 110 and the water temperature in the rice paddies and control the proper water feed and output the data for water feeding. The automatic water feeder 60 feeds water to the rice paddies based on the water feed data.
