The fertilizer applicator 10 is provided with a filter 5.

The utility model discloses more detailed description is as follows:

an automatic drip irrigation device for a greenhouse is connected with a water supply pipe and is characterized by comprising a drip irrigation pipe, a fertilizer applicator, a controller, a soil humidity probe and a power supply. The water supply pipe is connected with the drip irrigation pipe through a fertilizer applicator. The fertilizer applicator is provided with an electromagnetic valve and a valve for switching on and off water flow. The controller controls the closing of the electromagnetic valve by receiving a signal of the change of the soil humidity, so that the automatic drip irrigation is realized. In a preferable embodiment, the fertilizer applicator is provided with a filter and an electromagnetic valve, and the electromagnetic valve is connected with the controller. The controller is connected with a soil humidity probe, the soil humidity probe is buried under the ground surface of the drip irrigation pipe at the position of 8-12cm, and the controller regulates and controls the electromagnetic valve through signals transmitted by the soil humidity probe.

After the technical scheme is adopted, the beneficial effects of the utility model are that automatic drip irrigation device passes through the fertilizer applicator and links to each other with the delivery pipe, is equipped with solenoid valve and the valve that is used for switching rivers on the fertilizer applicator, and the solenoid valve links to each other with the controller, is connected with the probe of response soil moisture on the controller, drips irrigation through installing in drip irrigation pipe the water drip evenly and slowly instil into near the soil of crop root zone, makes moisture infiltration and diffusion in soil, supplies crop root system to absorb and utilize. The controller automatically regulates and controls the drip irrigation operation according to the change of the soil humidity: when the soil humidity gradually decreases and reaches the set value of the controller, the controller controls the electromagnetic valve to open for drip irrigation; when the moisture permeates to the soil humidity probe and the soil humidity is higher than the set value of the controller, the power is cut off and the drip irrigation is stopped. The drip irrigation device is used for drip irrigation, automatic drip irrigation can be achieved according to the change of soil humidity, meanwhile, watering and fertilization can be carried out synchronously, and labor and force are saved.
