The water content value data and the temperature value data are well understood, and the EC value data are used for measuring the concentration of soluble salt in a solution and can also be used for measuring the concentration of soluble ions in liquid fertilizer or planting media. EC values are expressed in mS/cm or mmhos/cm and the measurement temperature is usually 25 ℃. High concentrations of soluble salts can cause damage to plants or death of plant roots. Normal EC values range between 1-4mmhos/cm (or mS/cm). The content of soluble salt (EC value) in the matrix is too high, reverse osmosis pressure can be formed, and water in the root system is replaced, so that the root tip is browned or dried. Irrigation water EC values of less than 0.8ms/cm are generally required.
When the processor finds that any one of the numerical values is not satisfactory, such as the moisture value is too low, the EC value is too high or the temperature value is too high, the processor controls the on-off of the intelligent valve through the control platform, and then the circulation of the pipeline is controlled, and watering is realized. When the moisture value is too high, the watering is stopped. And when the EC value is too low, the crops are proved to lack fertilizer, the water-fertilizer mixing system is started to mix water and fertilizer, and then the water-fertilizer irrigation system is utilized to perform targeted irrigation. In the process of mixing water and fertilizer, nutrients required by different crops are different, and the nutrients can be selected by utilizing a database.
In the watering or fertilizing and irrigating process, in order to avoid excessive watering and fertilizing, watering or fertilizing and irrigating need to be stopped in time, so that the intelligent valve is intelligently controlled by using a control platform of the data acquisition and analysis system, and the circulation of water or fertilizer in the pipeline is completed through the on-off of the valve.
