Abstract

The invention relates to an automatic hydroponic cultivation system and method. The system comprises a PLC control system, and a nutrient solution circulation system, an illuminating system, a temperature and humidity adjusting system and an air circulation system which are connected with the PLC control system, and the nutrient solution circulation system is connected with multiple hydroponic frames. According to the system, according to the set temperature, humidity, air circulation time, nutrient solution EC value, PH value and the like, a nutrient solution reaching the set standards can beautomatically added, the nutrient solution flowing down from the hydroponic frames is recycled for secondary adjusting, the nutrient solution reaching the set EC value and PH value is output from a liquid storage barrel continuously, then the volume of addition and concentration of the nutrient solution are accurately controlled, and the growing environment of hydroponic plants is guaranteed.

Description

technical field [0001] The invention relates to a hydroponic planting system, in particular to an automated hydroponic planting system and an automated hydroponic planting method. Background technique [0002] Hydroponics is a commonly used method of plant cultivation in scientific experiments. It is widely used in the research of plant nutrition and plant physiology, especially in the study of the physiological functions of mineral elements and the application of chemical fertilizers. [0003] At present, hydroponic technology has been widely used in tobacco seedling cultivation technology, and floating seedling cultivation technology has become a mature technology and has been promoted. However, hydroponic technology has not been applied to soilless cultivation in the field or laboratory cultivation in the later stage. [0004] However, the current hydroponic devices still need to manually prepare liquid, adjust temperature, humidity, and replace nutrient solution. It is ...
