[0021] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0022] A shallow liquid flow closed-loop irrigation device, the device includes a cultivation frame 1, a plurality of cultivation troughs 2 are installed on the cultivation frame 1, the plurality of cultivation troughs 2 are arranged parallel to the cultivation frame 1 along the length direction of the cultivation frame 1, and the cultivation troughs 2 can move along the cultivation frame 1. Optionally, a transmission mechanism is provided under the cultivation trough 2, which can move the cultivation trough 2. The transmission mechanism can be made of existing technology and will not be described here. As the plants grow, the plants need more growth space. The progressive cultivation troughs 2 meet the growth characteristics of the plants. The cultivation troughs 2 can be moved regularly on the cultivation frame 1, and the distance between two adjacent cultivation troughs 2 increases with the movement of the transmission mechanism. In other words, on a cultivation frame 1, the cultivation trough 2 at one end corresponds to the plant in the planting cultivation period, and the cultivation trough 2 at the other end corresponds to the plant in the maturity period.

[0023] The cultivation trough 2 is provided with a plurality of planting holes and an irrigation hole at one end of the cultivation trough 2. The cultivation trough 2 is a double-layer PVC structure with a rectangular cross-section. The inner layer of the cultivation trough 2 is black and the outer layer is white. The diameter of the planting hole is 32 mm and the hole spacing is 15 mm. The irrigation hole is a 50*50 square hole. In this embodiment, the cultivation trough 2 is divided into a cultivation trough A and a cultivation trough B. The two cultivation troughs 2 are placed on the cultivation rack 1 at intervals, and the planting holes of the two cultivation troughs 2 are staggered.

[0024] An irrigation main pipe 3 is laid at one end of the cultivation rack 1. The irrigation main pipe 3 is laid at one end along the width direction of the cultivation rack 1. Multiple irrigation branch pipes 4 are connected to the irrigation main pipe 3 through a pressure-stabilizing joint. The irrigation main pipe 3 is a PE pipe, and the irrigation branch pipe 4 is a PE capillary tube. In order to prevent the irrigation branch pipe 4 from deforming due to its soft texture, multiple irrigation branch pipes 4 are fixed by a branch pipe fixing member 5, and each irrigation branch pipe 4 corresponds to an irrigation hole and the end of the irrigation branch pipe 4 is located above the irrigation hole. The branch pipe fixing member 5 can be a common plate member, and the plate member is perforated so that each irrigation branch pipe 4 passes through the perforation and the end is exposed. Both ends of the pipe member are fixed on the cultivation rack 1.

[0025] The other end of the cultivation frame 1 is provided with a drainage trough 6, which is provided at the other end along the width direction of the cultivation frame 1. The drainage trough 6 is located below the cultivation trough 2 and corresponds to the end of the cultivation trough 2. One end of the cultivation trough 2 provided with an irrigation hole is higher than the other end of the cultivation trough 2. That is, the nutrient solution flowing in from the irrigation hole passes through the entire cultivation trough 2 and flows out from the end of the cultivation trough 2. All the nutrient solution is collected in the drainage trough 6. The bottom of the drainage trough 6 is opened, and a PVC drainage pipe is connected through an adapter, and the nutrient solution is discharged from the drainage pipe.

[0026] In summary, the shallow liquid flow closed-loop irrigation device provided by the utility model can adjust the distance between each pipeline-type cultivation trough 2 according to the size of the leafy vegetable growth during the entire growth period after the leafy vegetable is planted. The leafy vegetable is located at different positions of the cultivation rack 1 at different growth stages. The position of the cultivation trough 2 is set according to different time nodes. The irrigation main pipe 3 selects a one-inch PE pipe, and the irrigation branch pipe 4 selects a PE capillary with an inner diameter of 4mm. The end is inserted into the corresponding hole position of the branch pipe fixing part 5, and the outlet of the irrigation branch pipe 4 is directly opposite to the irrigation hole. The drainage end of the cultivation trough 2 is open to ensure the shallow liquid flow form. A drainage trough 6 is fixed at the lower part of the drainage end of the cultivation trough 2. The nutrient solution in the drainage trough 6 is discharged to the nutrient solution pool along the drainage pipeline to complete the entire irrigation process.

[0027] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
