An automatic control three-dimensional drip irrigation method

Abstract

The invention discloses an automatic control three-dimensional trickle irrigation method, which comprises the steps that an automatic control three-dimensional trickle irrigation system is set; an upper limit signal and a lower limit signal of a soil water content are set, and the opening and closing of control valves are controlled; the automatic liquid supply for plants is realized by the opening and closing of the control valves; under the conditions that an Nth layer and an N+1th layer of control valves are opened simultaneously and a main pipe is always in a full-filling state under the water pressure effect and is a pressured pipeline, at the moment, the Nth layer and the N+1th layer of control valves are opened, water flow enters branch pipes under the pressure effect, the main pipe is rapidly filled due to the pressure difference effect, the water flow is continually supplied until a soil humidity sensor regulates. According to the invention, as a trickle irrigation technology is used, the utilization efficiency of water is high and can reach 90-95%, and the balanced irrigation of water and fertilizer is realized; since the irrigation method is combined with the sensor, the automatic opening and closing of a water supply valve are realized, and a time-saving effect is realized; the pressure which is generated by water self-weight is used as water supply power, so no unnecessary energy sources are consumed.

Description

technical field [0001] The invention relates to an automatic control three-dimensional drip irrigation method, which belongs to the technical field of irrigation. Background technique [0002] In modern cities, many families have flowers or plants planted on balconies or gardens. These plants need to be irrigated and fertilized at certain intervals, otherwise their growth will be affected or they will die. Urban people are busy with work and go out frequently, so they cannot regularly irrigate and fertilize plants, especially in summer and autumn. If plants cannot be irrigated in time, their growth will be affected or even die. Fertigation of homegrown plant species becomes more problematic when the nutrient requirements of these species are high and increase in quantity. Although it is possible to dissolve the necessary fertilizers in the water when watering the plants, so that the purpose of fertilizing the plants can be achieved while irrigating. But how to realize auto...

Problems solved by technology

This method effectively solves the problem that the water supply (fertilizer water) system of the existing household plant growth frame needs to consume additional energy as water supply power; it solves the water (fertilizer water) utilization rate of the existing household plant growth frame water supply (fertilizer water) system At the same time, it solves the time-consuming and labor-consuming problems of the existing household plant growth rack water supply (fertilizer water) system; at the same time, it solves the problem of unbalanced fertilization efficiency of plants to a certain extent
