The integrated device for arid agricultural water irrigation comprises a water storage well 1, an open ditch, and a hidden ditch 2, wherein the water storage well 1 is provided with a water storage chamber 11, the water storage chamber 11 is used to store water, and a water level sensor and a water quality detection component are arranged in the water storage chamber 11; the open ditch is connected to the water storage well 1, and there are a plurality of open ditch, and the plurality of open ditch are arranged on the ground surface; the hidden ditch 2 is connected to the water storage well 1, and there are a plurality of hidden ditch 2, and the plurality of hidden ditch 2 are arranged in the soil at a certain distance from the ground surface.

[0046] In this embodiment, the open ditch is an irrigation ditch arranged on the surface. According to the different root depths of crops, underground culverts 2 and water storage wells 1 are arranged in the field, interconnected, and monitored and regulated in real time. The culverts 2 and water storage wells 1 collect and store rainwater and irrigation infiltration water. The total capacity of the culverts 2 and water storage wells 1 is determined comprehensively based on rainfall, irrigation water volume, and water source conditions. The water storage wells 1 and culverts 2 are arranged according to the growth and water demand characteristics of farmland crops based on local topography and climatic conditions. Control gates and water meters are arranged at the inlets and outlets of the open ditch and culvert 2 to form a three-dimensional integrated irrigation and drainage working mode with real-time monitoring and regulation functions, including upper irrigation, middle infiltration, and lower collection and storage. Water level sensors and water quality detection components are both existing technologies, and no further explanation is given here. As long as they can achieve the relevant functions, they are within the scope of protection of this application.

[0047] Compared with the existing technology, this integrated water-adaptive irrigation device for arid area agriculture is based on the concept of efficient and circular utilization of multiple water sources such as rainfall, irrigation, surface water, groundwater, rainwater, recycled water, and mine water. It constructs a system of rainfall (irrigation) infiltration in arid areas-soil water recycling-shallow groundwater storage. The device introduces multiple water sources (such as conventional irrigation water sources such as surface water and groundwater, unconventional water sources such as rainwater, recycled water, mine water, as well as irrigation infiltration, drainage or mixed water sources, etc.) for internal circulation, and maximizes the recycling of existing water sources. Rainwater, recycled water, mine water and other water sources that meet the irrigation water quality requirements within the region, as well as irrigation infiltration and drainage, are collected and stored in the culvert 2 and the water storage well 1, so as to expand the scope of irrigation water sources and improve the regional water supply capacity; irrigation is carried out based on comprehensive consideration of the available water volume, the growth stage of local crops and the critical water demand threshold, and recycling is achieved within the farmland to reduce the loss of fertilizers and other materials with water due to drainage, thus achieving efficient use of water at the farmland scale, reducing external discharge and reducing non-point source pollution; the near-surface groundwater level is regulated through irrigation-storage and drainage of water in the culvert 2 and the water storage well 1, thereby increasing the utilization rate of unconventional water sources such as rainwater, recycled water and mine water and improving the regional ecological environment and microclimate.

According to the farmland water migration process, the recycling degree and water use efficiency are improved from the links of increasing water sources (rainwater, recycled water, mine water and other water sources), reducing migration losses (ground coverage to reduce evaporation) and water collection and recycling (storage well 1, culvert 2 storage and collection of rainwater, drainage, etc.), real-time monitoring of weather, soil and plant growth, and comprehensive regulation of irrigation based on the available water, the growth stage of local crops and the key water demand threshold. According to different situations in the crop growth process, it is summarized into three operation modes: when the arid agricultural water-adaptive irrigation and drainage integrated device is in a water shortage state, and the water stored in the system cannot meet the water needs of crops, it is necessary to supplement water from the outside; when the arid agricultural water-adaptive irrigation and drainage integrated device is in a moderate water supply state, the water stored in the device can meet the water needs of crops, there is no need to supplement water from the outside, and the water source only circulates internally at this time; when the arid agricultural water-adaptive irrigation and drainage integrated device is in an excess water storage state, the water stored in the device can meet the water needs of crops and the collected water exceeds the total storable amount, there is no need to supplement water from the outside and the excess water needs to be discharged into the river.
