A method for cultivating green bean sprouts based on pottery jars

Abstract

The application relates to the technical field of intelligent seedling cultivation, and discloses a mung bean sprout cultivation method based on a pottery jar. A piezoelectric ceramic acoustic emission sensor is embedded in a double-layer pottery wall annular cavity, sound emission signals generated by root growth are collected, after amplification and band pass filtering, third to fifth layer energy entropies are extracted through wavelet packet decomposition as root activity characteristic indexes; a stress discrimination model is constructed based on the root activity characteristic indexes, and water replenishment or aeration regulation is automatically triggered. The system comprises a pottery jar body integrated with a sensor, a porous tray, a signal processing unit, a discrimination control unit and an execution mechanism. The application realizes nondestructive, real-time monitoring and intelligent intervention on the state of mung bean sprout roots, significantly improves the cultivation success rate and quality consistency, and has low power consumption, compact structure and compatibility with traditional pottery aesthetics.
