Design of intelligent water and fertilizer integrated system for facility tomatoes
The traditional methods of tomato irrigation and fertilization are mainly drip irrigation and foliar spraying,relying on manual experience,which not only has a low utilization rate of water and fertilizer,but also is prone to cause problems such as unreasonable nutrient input ratio and serious waste.In response to the above issues,this study proposed an intelligent water and fertilizer integration system for facility tomatoes based on wireless sensor network technology and automatic control technology.The system built an environmental information collection system,intelligent service platform,irrigation and fertilization system,and greenhouse automatic control system based on factors such as target yield,plant growth potential,and fertilizer requirements of facility tomatoes,which could monitor the growth environment and development of facility tomatoes in real time.According to the fertilizer requirement law of different tomato growth stages,the system achieved timed and quantitative control of irrigation and fertilization,fully improving the utilization efficiency of water and fertilizer.
