Abstract

The invention relates to an intelligent cultivation system of sweet potatoes through drip irrigation. The intelligent cultivation system comprises a water tank, wherein the water tank is connected with a main water pipeline through a water inlet pipe, a filtering device, a drip irrigation pump and a first electromagnetic valve are in connection in series to the main water pipeline, one or more branch pipelines are arranged on the main water pipeline, and a second electromagnetic valve and a flowmeter are arranged at one end close to the main water pipeline, of each branch pipeline; one or moredrip irrigation heads are arranged on each branch pipeline, and a humidity sensor is arranged on the corresponding branch pipeline; and the drip irrigation pump, the first electromagnetic valve, thesecond electromagnetic valve, the flowmeter and the humidity sensor are all connected with a control system. The humidity sensor is used for real-time detection of soil moisture, the control system can realize intelligent drip irrigation of the sweet potatoes according to the soil moisture, the human resources are saved, and the drip irrigation efficiency is improved. The main water pipeline is connected with the filtering device, a multi-layer filtering net is arranged at each drip irrigation head, and a cleaning device is arranged, so that impurities and granular pollutants in the pipelinesand the drip irrigation heads can be timely filtered off, and plugging is avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an intelligent drip irrigation cultivation system for sweet potatoes. Background technique [0002] Drip irrigation is an irrigation method that slowly and evenly drips water with a certain pressure into the soil near the root of the plant through the orifice or dripper on the pipe after filtering. Under the condition of drip irrigation, the effective utilization rate of water is high, and the irrigation water wets part of the soil surface, which can effectively reduce the ineffective evaporation of soil moisture. At the same time, it can be combined with fertilization to increase the fertilizer efficiency by more than double. It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and can also be used for irrigation of field crops in places where there is drought and water shortage. [0003] In the prior art, most of the drip...
