Background
At present, land irrigation modes mainly comprise flood irrigation, sprinkling irrigation, drip irrigation, furrow irrigation, limited irrigation, under-film irrigation and the like. The traditional irrigation modes such as flood irrigation, furrow irrigation and the like not only have large irrigation quantity, are easy to cause evaporation among plants and increase transpiration quantity of plants, but also cause a large amount of water to leak to the deep layer of soil, thereby causing serious waste of water resources.
Currently, for example, chinese utility model patent with patent publication No. CN206165357U discloses an irrigation system capable of automatically determining whether the moisture in the green land is sufficient. Including tank, water delivery device and the soil body layer of being irrigated, water delivery device includes the water pump and drips irrigation the pipe, still includes the feedback device that catchments, the feedback device that catchments is including setting up the french drain of soil body layer below and the collector pipe of connecting the french drain, the collector pipe is equipped with the liquid monitoring ware that can pass through feedback signal control water pump, collector pipe and tank intercommunication. When the water content in the land is insufficient, the blind ditch can not collect water, the liquid monitor can not detect water flow, the water content is judged to be insufficient, the water pump in the water delivery device is controlled to be started, and the water in the water storage tank is delivered to the irrigated land layer. When water permeates the soil body layer and enters the blind ditch, the water is collected through the water collecting pipe, the liquid monitor detects water flow, the water is sufficient, the water pump is controlled to be closed, and irrigation is stopped.
The above prior art solutions have the following drawbacks:
by adopting the irrigation method, a large amount of water resources are absorbed by soil and evaporated, but not directly absorbed by plant roots, so that the utilization rate of the plants to water is greatly reduced.
