The embodiment of the invention provides an intelligent irrigation method and device. The method comprises the steps that the stem moisture content of crops to be irrigated at all time points is obtained; the transpiration of the crops to be irrigated at each time point is obtained; an irrigation model is established according to the transpiration and the stem moisture content, and the irrigationmodel is the corresponding relation between the stem moisture content and the transpiration at each time point; the stem moisture content at each time point is compared to obtain a daily minimum valueof the stem moisture content; curve fitting is carried out on the daily minimum value and the corresponding date to obtain a fitting curve, and the slope of the fitting curve is detected; when the slope is smaller than a preset slope, the corresponding stem moisture content is obtained, and the current-day transpiration corresponding to the stem moisture content is obtained in combination with anirrigation model; and the corresponding irrigation devices are driven to irrigate the crops to be irrigated, and the irrigation water flow is made to be equal to the transpiration of the day. By theadoption of the method, an intelligent irrigation control strategy for conducting irrigation according to the stem moisture content can be provided.
Description
technical field [0001] The invention relates to the field of irrigation control, in particular to an intelligent irrigation method and device. Background technique [0002] The water requirement of traditional agricultural crops in my country refers to the amount of water consumed by crop growth and development. Studies in recent years have shown that crops have physiological water-saving and drought-resistant capabilities. The water requirements of crops are different in each growth stage, and the sensitivity of each growth stage to water is different. Insufficient irrigation cannot meet the production needs of crops, and excessive irrigation will also affect the growth of crops. [0003] At present, the main basis for intelligent irrigation of crops in China is to refer to the corresponding soil moisture of the crops. The soil moisture can partially reflect the current water demand of the crops. According to the different types of crops, different soil moisture indicators...
