Fuzzy control system for hydroponics cultivating

The main process in hydroponics plants cultivating is aquatic induction. Aquatic induction is the process of cultivating plants in the right artificial environment to induce aerenchyma formation, which can make plants be grown in water. With long-time practices and researches, rules and environment parameters for aquatic induction was summarized. And a set of fuzzy control system for hydroponics cultivating was developed. Making use of the experience from practices, a method was put forward to control dissolved oxygen, CO₂ and EC in some hydroponics cultivating greenhouses without oxygen detector, CO₂ detector and EC detector. The result of the system running shows that the system can achieve hydroponics cultivating without watchers.
