detailed description

 The present invention will be further described below in conjunction with the accompanying drawings.

 As shown in Figures 1 to 5, the invention irrigation system includes a central control system 1 and an irrigation system controlled thereby

2. It also includes a irrigation and drainage system controlled by a central control system. 3. A recovery system 4. The central control system includes a monitoring system 12 and a control system 14; wherein the monitoring system includes air and soil temperature and humidity, solar lighting, raining moisture and wind direction and wind speed monitoring system 122 and nutrient monitoring system 124, control system Including irrigation and control centers for temperature and humidity of air and soil in the greenhouse, solar lighting, rain and moisture and wind speed, sprinkler irrigation and drip irrigation, or irrigation control centers for irrigation, sprinkler and drip irrigation in the open air. 142 and irrigation control center for nutrient irrigation, sprinkler irrigation and drip irrigation 144. The irrigation system for irrigation, sprinkler irrigation and drip irrigation comprises an irrigation pipe network 22 for seepage, sprinkling and drip irrigation formed by a plurality of vertical and horizontal irrigation, sprinkling and drip irrigation pipes 20, and the irrigation pipe network and The water storage tank 5 communicates with the water pump 6 at the inlet of the irrigation pipe network; as shown in Fig. 5, the irrigation pipe 20, which can be used for irrigation, sprinkling and drip irrigation, comprises an outer pipe 201 and a plurality of openings on the outer pipe wall. The outer wall drainage hole 202 is further provided with a main water channel 203 in the outer pipe, the main water channel is V-shaped, and a plurality of inner wall drainage holes 204 are arranged at a position on the wall of the main water channel higher than the outer wall drainage hole. The irrigation and drainage system comprises a drainage pipe network 32 formed by a plurality of vertical and horizontal irrigation pipes connected to each other, and an outlet thereof communicates with the water storage tank 5 through a valve 7, and a filtering device 8 may be disposed between the outlet and the water storage tank. The drain pipe is the same as the irrigation pipe that can be used for irrigation, sprinkler irrigation and drip irrigation. Working wells 9 are provided at both ends of the boundary of the irrigation zone. The irrigation and drainage system further includes an anti-leakage system 34, including a water-impermeable adhesive film 10 disposed at the bottom of the irrigation layer; the working well has a depth greater than the height of the irrigation zone, and a water-impermeable film is also disposed in the working well. The drainage pipe network is arranged in the middle of the entire irrigation layer, and the same drainage pipe network 11 can be disposed under the watertight film at the bottom of the irrigation layer.

When using this system, set up a target working area for each piece, and lay the waterproof film to a suitable depth, open a trapezoidal working well on both sides, and bury the drainage pipe network in the middle to set the seepage at the surface. Irrigation, sprinkler irrigation and drip Irrigation pipe network. If the monitoring system controlled by the central control system is generally a sensor, when the temperature and humidity of the air and soil in the target operating area, solar lighting, raining moisture or nutrient data are low and the scientific reference data is low, a feedback will be given. The signal is sent to the control system so that the central controller gives a signal to the irrigation system for irrigation, sprinkler irrigation and drip irrigation, which should supplement the missing parts of the soil to ensure the best growing soil environment for the crop. If the monitoring system detects that the humidity exceeds the standard during the dry season, the irrigation and drainage system will be automatically activated, so that excess water is discharged from the drainage pipe into the storage tank of the recovery system; When there is too much water in the surrounding environment, water will be drained from the drainage pipe into the storage tank, so that the water can be prevented from being lost or the base of the entire target operation area is unstable. The water stored in the storage tank can be recycled during the spraying of the sprinkler irrigation and percolation system in the dry season, and the part of the water is sent to the sprinkler irrigation and seepage irrigation pipes by the pump, and a filtering device is arranged between the pump and the storage tank. It is also possible to set up a system such as a sedimentation device to process water. A valve is arranged between the outlet of the irrigation pipe network and the storage tank, and the drainage pipe network can also serve as a sprinkler irrigation and percolating device for the intermediate soil layer when the valve is closed, and can supplement the water in the effective range at the position. Parts and nutrients. Valves can also be placed between the inlet of the irrigation pipe network and the pump. In the working well, the real-time state of the irrigation system and the irrigation and drainage system can be directly seen by humans, the basic situation of the soil can be grasped, and the human control can be controlled when the central control system has problems. In addition, a level can be set in the working well to monitor whether the drainage system in the middle layer or the surface is in a horizontal state with the other pipe of the drip irrigation system. If not, it can be artificially adjusted.

Of course, the waterproof film can be laid on the bottom layer of the wave-shaped target work area, or it can be laid on the bottom of the flat target work area. In addition, in order to make the bottom drain pipe better absorb excess water, a layer of pebbles can be laid on the bottom layer. The middle drainage pipe network and the bottom drainage pipe network can be arranged at intervals of the staggered layout.

 It can also be used in conjunction with the film on the soil surface to reduce evaporation and maintain soil temperature, saving irrigation water. At the same time, the irrigation, sprinkler and drip irrigation pipes and drainage pipes can be set in different regions and different crops and according to different purposes, different pipe diameters and different pore sizes can be set.

Of course, it is also possible to provide an atomizing device that can atomize water entering the irrigation system or a liquid containing nutrients, etc. in the working well; or a humidifying aerator that can be humidified or oxygenated, through the mist. The sound wave of the chemical device can atomize part of the water, thereby increasing the contact area and facilitating absorption; if the surrounding soil environment or the moisture in the air is excessive, a ventilator or a dryer can be installed. The irrigation pipe greatly reduces the humidity in the air or in the soil environment. Especially when it comes to soilless greenhouse cultivation, it can absorb crops more effectively. By increasing the temperature and increasing oxygen, it is possible to maintain the humidity and oxygen concentration of the surrounding air during drying, and to change the crop growth environment, thereby increasing the production value. Of course, after the crop is harvested, the soil can be modified before the soil can be used again. In the process of remediation, irrigation pipe spray disinfectant or high temperature steam can be used for disinfection, so that there is a more qualified soil environment when the second crop is planted.
