Nutrient supply control system based on water content of plants growing medium and weight of plants

摘要

The present invention relates to a nutrient supply control system for controlling the nutrient supply according to the water content and the weight of plants of a plant cultivation medium and includes a first flow sensor for measuring the amount of nutrient solution fed into the planted plant medium, A weight sensor for measuring the weight of the medium in which the plant is planted and a second flow rate sensor for measuring the amount of the nutrient solution discharged from the culture medium, the measuring device for transmitting the measurement information of each sensor, A control device for calculating the amount of absorption of the nutrient solution absorbed by the plant and calculating the weight of the plant to control the composition, injection timing, infusion rate and amount of the nutrient solution fed to the culture medium, thereby controlling the water content of the medium And it provides an optimal cultivation environment of plants, which enables economical precision agriculture.
