Soilless culture substrate liquid discharge amount monitoring device

According to the technical scheme, the soilless culture substrate drainage amount monitoring device is characterized in that the soilless culture substrate drainage amount monitoring device comprises a substrate bag, and substrate percolate can enter a drainage collecting barrel along with a reserved special flow channel. At the moment, the matrix scale which operates in real time for 24 hours can timely weigh the weight change and synchronously transmit the weight change to a software data platform. Therefore, data such as the first drainage time and the total drainage amount can be mastered. And in combination with irrigation volume data, an important index for judging whether irrigation is reasonable or not is obtained by calculating a liquid discharge ratio, so that the change conditions of matrix parameters such as temperature, humidity, pH value and conductivity of different tank bodies and different matrixes under different climates can be conveniently determined. If the parameters are changed extremel
