Background
With the continuous transfer of rural population in China to cities and the continuous reduction of available cultivated land in the cities, the development of urban facility agriculture has important significance for guaranteeing the daily fruit and vegetable supply of the cities. In the greenhouse soilless culture process, the supply of water and fertilizer and the control of greenhouse illumination and temperature are all important for the growth of crops. Therefore, the advanced control technology is adopted to automatically control the water and fertilizer supply, illumination and temperature in the greenhouse, and the method has important significance for reducing agricultural non-point source pollution caused by fertilizer loss and guaranteeing economic benefit.
At present, the water and fertilizer integrated mode is generally adopted in facility agriculture to realize the supply of crop water and fertilizer. In the process of supplying the water and the fertilizer, EC detection is usually adopted to monitor the concentration of the fertilizer, so that the precise supply of the water and the fertilizer is realized. EC reflects the ion concentration of the water fertilizer, belongs to comprehensive evaluation indexes, and interference of other irrelevant ions has no practical guiding significance for realizing precise quantity supply of the water fertilizer. Near infrared spectrum detection is a rapid and nondestructive detection technology and is widely applied to the fields of agriculture, food, medical treatment and the like. At present, no research report for realizing the monitoring of the concentration of the fertilizer by adopting near infrared spectrum detection exists, and the detection of various concentrations of the fertilizer in the water fertilizer by adopting the near infrared spectrum has important significance for realizing precise fertilization. In addition, in the process of spraying water and fertilizer to greenhouse crops, some water and fertilizer which is not sprayed to the surfaces of the crops enters underground water through surface runoff loss, so that underground water resources are seriously polluted and waste of the water resources is caused. And to the control of facility greenhouse illumination and temperature, often adopt manual operation fan ventilation and artificial control LED lamp light filling etc. to realize, its degree of automation is low, intensity of labour is big and to the condition of illumination deficiency be difficult to realize automatic light filling. Therefore, the automatic water and fertilizer application and the automatic greenhouse environment control are integrated by adopting an advanced control technology, and the method has important significance for reducing the greenhouse production investment and improving the greenhouse automatic production water average.
