Embodiment 1
[0034] Such as figure 1 As shown, the embodiment of the present invention provides a method for recycling irrigation utilization, comprising the following steps:
[0035] Open several ditches 1 on the ground in the greenhouse, lay a PE film 2 in the ditches 1, place a cultivation substrate 3 on the PE film 2, and wrap the cultivation substrate 3 with the PE film 2;
[0036] Make a nutrient solution return hole 4 at the bottom of the film at one end of the trench 1, and connect the recovery branch pipeline 5 outwards through the hole 4, and the recovery branch pipeline 5 is connected to the recovery main pipeline 6. The nutrient solution flows into the recovery bucket 8 through the recovery main pipeline 6, and the recovery bucket 8 is positioned lower than the trench position;
[0037] The recovery barrel 8 is provided with a pumping device, the pumping device is connected to the fertilizer distribution bucket 10 through the circulation pipeline 9, and the nutrient solution i...
Embodiment 2
[0046] Such as figure 2 As shown, the embodiment of the present invention also provides a circular irrigation utilization system, including a surplus nutrient solution recovery subsystem, a recovery bucket, a fertilizer bucket and irrigation pipes;
[0047] Such as image 3 As shown, the nutrient solution recovery subsystem includes a trench 1, a PE film 2, a cultivation substrate 3, a recovery branch pipeline 5 and a recovery main pipeline 6, the PE film 2 is laid in the trench 1, and the PE Place the cultivation substrate 3 on the film 2, wrap the cultivation substrate 3 with the PE film 2; make a nutrient solution return hole 4 at the bottom of the PE film at one end of the trench 1, and connect the return flow hole 4 through the hole 4. Incoming and outgoing pipelines 5, the recovery branch pipelines 5 are all connected to the recovery main pipeline 6;
[0048] The recovery main pipeline 6 is connected to the recovery bucket 8, and the recovery bucket 8 transmits the nu...
