The anti-slip layer can be provided with an anti-slip structure which can be anti-slip lines or anti-slip bulges 131.

Because the lifting part in this embodiment adopts the speed reducer 128, when the speed reducer 128 stops moving, the positioning of the position of the follow-up assembly on the guide rail 121 can be realized, and optionally, the speed reducer can be a worm gear speed reducer. Two position switches can be further arranged on the guide rail 121, wherein one position switch is used for stopping the follow-up assembly at the high state of the capillary 102, and the other position switch is used for stopping the follow-up assembly at the low state of the capillary 102. It should be noted that the electric mortise lock can also be used to position the follow-up assembly on the guide rail 121, when the position switch at the high position stops the follow-up assembly at the high position of the tubular billet 102, the bolt of the electric mortise lock at the high position extends out to stop the follow-up assembly, when the follow-up assembly needs to move, the bolt of the electric mortise lock at the high position retracts, and similarly, the bolt of the electric mortise lock at the low position extends out to stop the follow-up assembly. In addition, the position switch can be replaced by a photoelectric switch.

In this embodiment, the operating principle of the lifting portion is: the motor 127 drives the speed reducer 128 to rotate, the speed reducer 128 drives the transmission assembly to move, the transmission assembly drives the follow-up assembly to move along the guide direction (namely the length extension direction of the curve) of the guide rail 121, when drip irrigation operation is needed, the follow-up assembly is moved to a low position state, and when the follow-up assembly touches the position switch, the motor 127 stops moving. When spraying is required, the follower assembly is moved to a high position state, and when the follower assembly touches the position switch, the motor 127 stops moving.

In this embodiment, the operation method of the header hub is as follows: when the water is irrigated, the second switch 116 is closed, and irrigation is carried out according to the irrigation quota. When in fertilization, the second switch 116 is opened, the N, P fertilizers are supplied to the fruit tree in a drip irrigation operation mode, the two fertilizers are respectively put into different fertilization tanks 107 according to the water-fertilizer ratio, and are injected with irrigation water for dissolution and stirring; setting a fertilizer suction ratio in a PLC control system in advance, and opening a first electromagnetic valve 109; the K element and other trace elements (such as Mn element), pesticide and the like are applied in a high-position operation mode; when high-level operation is performed, the first switch 106 is first opened, and water is pumped into the main pipe 101 and the capillary 102 by the first pumping device 105, so as to flush the main pipe 101 and the capillary 102. Similarly, when the low-level operation is performed, the main pipe 101 and the capillary 102 need to be flushed by the first pumping device 105.

One specific application of the water-fertilizer-pesticide integrated irrigation system can be that the application time and the application amount of water, fertilizer and pesticide for pear tree planting are shown in the table I.

Table one:

in table one, date and time both refer to date, i.e., month and day, e.g., 4.2 refers to 4 months and 2 days; the bud stage 4.1-4.15 refers to 4 months 1 to 4 months 15.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
