Abstract

The invention belongs to the technical field of agricultural water-saving irrigation, and discloses an agricultural water-saving irrigation system including a video monitoring module, a water detection module, a temperature detection module, a main control module, an irrigation area determination module, a water demand calculation module, a water pumping module, a spraying module, an alarm moduleand a display module. Accurate data of the maximum soil surface water-seepage rate, the actual soil surface water-seepage rate and primary irrigation water demand are obtained through the water demandcalculation module, and the normal operation of farmland irrigation activities is ensured; meanwhile, through the irrigation area determination module, an irrigation area monitoring method based on the corrected vertical drought index difference threshold is established, the actual irrigation area can be monitored by a satellite remote sensing means and a fewer of ground calibration points, the calculation accuracy of the irrigation water amount is improved, and the management level and the water use efficiency of the irrigation area are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and in particular relates to an agricultural water-saving irrigation system and a control method. Background technique [0002] Irrigation is a technical measure to replenish the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. Irrigation, i.e. irrigating the land with water. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of medicinal plants, growth stages, climate, and soil conditions, and should be timely, ...
