Abstract

The invention discloses an irrigation device based on root region soil moisture stress response. The device comprises a water supply tank, a transit water tank and a root irrigation pipe, wherein thewater supply tank, the transit water tank and the root irrigation pipe are sequentially connected into a loop through a pipeline, and the transit water tank is also connected with a Markov bottle; electromagnetic valves are arranged among the water supply tank, the transit water tank and the root irrigation pipe separately and electrically connected with a controller. The controller is also connected with a plurality of sensors which are arranged around the root irrigation pipe. In addition, the invention also discloses an irrigation method of the device. The device is applied to various agricultural production conditions in arid areas and cooperatively used in a stage-by-stage water supply mode, so that the relative stability of the soil water content in root areas is ensured, most agricultural irrigation water is saved, the loss and waste of water resources are prevented, the consumption of electric power and other energy is reduced, and the input cost of agricultural production is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation equipment, and in particular relates to an irrigation device based on root zone soil water stress response, and also relates to an irrigation method using the device. Background technique [0002] In the process of farmland crop production, moderate water supply can not only improve the metabolism of crops, but also promote the growth of crops, which is a necessary condition for crop growth and production. Especially in arid areas, the process of crop growth requires artificial irrigation for field soil water replenishment to meet the normal water demand of crop growth. Since the development of field irrigation, many irrigation forms have appeared, such as flood irrigation, drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, infiltration irrigation and root irrigation. The choice of irrigation form is mainly to meet the needs of different crops for soil...
