Method for automatic watering of plants relates to crop production and is designed for automatic selective watering of plants.

The known method for automatic watering of plants, implemented in the device for automatic watering of plants [1]. The device comprises a container with the medium to grow at least two plants, which drop inlets with holes for supplying irrigation fluid to the plants, container for the spray fluid dispensing irrigation fluid, having an output tube with a tip, a displacement device of the handpiece and software device with an automatic control device of the flow of irrigation fluid and a displacement device of the handpiece according to prescribed programs. The actuator to move the tip is used to move from one of a suction nozzle to another at a distance equal to the distance between the suction nozzles. Irrigation method, implemented in the design of the facility allows for individual watering each plant with the desired flow rate of irrigation fluid.

The disadvantage of this method of irrigation is the lack of the ability to flexibly change the watering places whose location depends on the location of the receiving ports.

The closest the �technical essence and the achieved result is a method of automatic watering of plants implemented in the device for automatic watering of plants [2]. A device for automatically watering plants comprising a container with a medium for growing plants, container for the spray fluid dispensing irrigation fluid, having an output tube with a tip, a displacement device tip having a mounting leg, and program the device with the possibility of automatic control of the dispensing irrigation fluid and a displacement device of the handpiece according to prescribed programs. The tip is set at an angle to the container with the medium for growing plants and is movable along its axis, and mounting legs of the device for moving the tip in an L-shape, with one of the tribes of the leg is located beneath the container with the medium for growing plants. Irrigation method, implemented in the design of the facility allows for individual watering each plant with the desired flow rate of irrigation fluid and manually change the location of the device movement of the tip relative to the capacity of the environment for the cultivation of the plants and the tip and, thus, to adjust the location of watering all the plants at the same time as they grow.

The disadvantage of this method of irrigation is that it does not pre�provided the possibility of independent change of the places of watering for each plant individually.

The problem solved by the invention is to ensure the possibility of independent change of the places of watering for each plant individually. The task is achieved in that in the method of automatic irrigation of plants comprising feeding a regulated amount of irrigation liquid to the plant via a pump and sprinkler heads, moving from plant to plant by using the managed software from a drive device, prior to the implementation of cycle automatic irrigation sprinkler head located in the initial position, is supplied by the actuator in manual control mode, to each plant in turn and stops. In-memory software device recorded the coordinates of the stopping places, after which it is returned by the actuator to its initial position, at which the software and the device is in automatic mode playback stopping places.

In the proposed method, it becomes possible flexible, independent changing of watering for each plant individually through the software settings of the device in the adjustment mode taking into account the required watering places and subsequent auto-play a predetermined law of motion of the sprinkler head. With the growth of plants or transplant them, i.e. when you change the ground floor�VA, you need to make a conversion software devices.

Fig.1 shows a diagram of the implementation of the method.

The method is carried out as follows. Supply irrigation fluid to the plant 1 is carried out from the tank 2 by the pump 3, hose 4 and sprinkler heads 5. The movement of the sprinkler head 5 from plant to plant by using the actuator. It consists of a carriage 6, guide 7, a belt transmission 8 and the stepping motor 9. The operation of the stepper motor 9 and the pump 3 controls software device 10. Prior to the implementation of cycle automatic irrigation sprinkler head 5, which in the initial position, is supplied, in the manual control mode, to each plant 1 turn and stops. In the memory of the programming device 10 are fixed locations are stopping sprinkler head and set the watering duration. Then spray head 5 is returned to its original position at which the programming device 10 is translated in automatic play mode stopping places. When the set start time watering sprinkler head 5 automatically makes the move from the initial state to each plant 1 alternately. Upon reaching the plants 1 she stops, turns on pump 3 at the time of the presumed races� " s irrigation duration, and irrigation fluid from the tank 2 through the tube 4 and the spray head 5 is supplied to the plant 1. After last watering plants sprinkler head 5 moves to the starting position.

The efficiency of the method was checked when automatic selective watering of ten plants planted at different distances from each other in the box in terms of size 200*700 mm. Software device containing a microcontroller (ATmega 328, which governed the operation of the stepper motor and pump according to the control program by means of two electromagnetic relays. Prior to the implementation of cycle automatic irrigation sprinkler head located in the initial position, summing up, in the manual control mode, to each of ten plants in turn and stopped. In-memory software device recorded the coordinates of the places you stop watering heads and wondered, use the keypad to program the device for the duration of watering each plant in seconds. It was for different plants range from 5 to 15 seconds. After which the sprinkler head is returned to its original position, at which the software device was transferred into auto play mode places the stop of the sprinkler heads and irrigation duration. When the set start time watering sprinkler head � automatic mode made the move from the initial state to each plant in turn. Upon reaching the plants she would stop, turn on the pump at the time established for this plant irrigation duration, irrigation fluid from the tank through a hose and sprinkler head was fed to the plant. After tenth irrigation plant watering head is moved to the initial position.
