The control method for drip irrigation according to fruit tree's demand for soil water content
with the apparatus as described above, the method includes the following steps:
a. pre-irrigation: pre-irrigate the orchard that will be drip-irrigated, and ensure that the soil
water content is greater than the minimum value of the current water content requirements of the
fruit trees;
b. drip irrigation pipeline layout: a drip irrigation branch pipe 11 is arranged on one side of
each column of fruit tree bodies for drip irrigation, multiple of drip irrigation capillaries 12 are
arranged on the drip irrigation branch pipe 11, and the drip irrigation capillaries 12 correspond to
the fruit tree bodies;
c. installation of the apparatus for irrigating according to the requirements of the fruit trees for
the soil water content: bury active control device for soil water content feedback into the soil
layer, and ensure that active control device for soil water content feedback is maintained at a
distance of 50 cm from the fruit tree trunk; connect the driven waterway control device with the

In step c, the depth of active control device for soil water content feedback in the soil is

In step c, the distance between the nozzle end of the water pipe 7 on the driven waterway
control device and the trunk of the fruit tree is 10cm.
The working principle of the device in the present invention is:
Different soil depths in the soil have different water content. The water penetrates into the
hollow part of the hollow clay head 1, and it will interact with the polymer material that has the properties of water swelling and water loss shrinking. The polymer material can be water-swelling rubber. The water-swelling rubber has a fixed expansion rate and shrinkage rate, after absorbing water and expanding, it will push the piston 3 up, the push rod 4 connected with the piston 3 will slide upward in the guide connecting pipe 6, and the valve plate 9 located in the valve housing 8 will overcome the action of the spring 10 and move upward, thereby close the nozzle of water pipe
7. When the soil water content drops, the water-swelling rubber shrinks, and then cooperates with
the spring 10 to move the valve plate 9 down. When the soil water content drops to the minimum
value required by the fruit trees for soil water content, the waterway of the water pipe 7 is
completely opened, and the water in the drip irrigation branch pipe 11 flows into the soil through
the drip irrigation capillary 12 to perform drip irrigation for the fruit trees. The triggering of the
driven waterway control device by different soil water content is realized by the screw adjustment
between the screw cap 5 and the shell tube 2. When the screw cap 5 rotates upward for a certain
distance, the relative height of the piston in the shell tube 2 rises, and the action of the driven
waterway control device can be triggered only when the soil has a higher water content value.
The valve housing 8 is made of transparent material, which is convenient for observing the
movement of the valve plate 9 in the valve housing 8 and distinguishing whether there is a problem
with the device.
The screw cap 5 and the guide connecting pipe 6 are made of rubber or plastic, which mainly
utilizes their anti-corrosion properties.
The push rod 4 is made of steel wire, and the push rod is mainly in the form of sliding in the
guide connecting pipe, and the guide connecting pipe 6 needs to be used as a track.
When the deflection of the guide connecting pipe 6 is smaller than that of the push rod 4,
when the guide connecting pipe 6 does not undergo irreversible deformation, the function of the
push rod 4 should not be affected. When the deflection of the guide connecting pipe 6 is greater
than that of the push rod 4, when the push rod 4 does not undergo irreversible deformation, the
guide connecting pipe 6 should not affect the function of the push rod 4. This facilitates the
connection of the water pipe 7 and the drip irrigation capillary 12 and reduces the influence of
installation errors on its connection.
Take drip irrigation of the main mid-maturing variety Baifeng peach tree in Lanzhou as an
example, when the peach tree is in the period of rapid peach fruit expansion, which is the period from late July to early August in Lanzhou, the soil water content is required to reach more than
%; first, pre-irrigate the orchard to ensure that the soil water content of the peach tree is greater
than 60%; in this way, when installing the control apparatus for drip irrigation according to fruit
tree's demand for soil water content, it is convenient to observe the action of the valve plate and to
check the driven waterway control device. Arrange the drip irrigation branch pipe 11 on the same
side of the peach tree. The drip irrigation branch pipe 11 is supplied by the water source, and a drip
irrigation capillary 12 is set at the position of the drip irrigation branch pipe 11 corresponding to
the peach tree. Bury the active control device for soil water content feedback into the soil, and
meanwhile ensure that the distance between the active control device for soil water content
feedback and the trunk of the peach tree is maintained at 50cm, and the buried depth is controlled
at 40cm from the ground. The distance between the drip opening of the water pipe 7 and the trunk
of the peach tree is controlled at 10cm, try to ensure that the guide connecting pipe 6 is straight
when embedding; If it is bent, it is forbidden to be bent irreversibly. Connect the driven waterway
control device to the drip irrigation capillary 12 after embedding. The water in the soil and the
active control device for soil water content feedback need a certain time to act. The valve plate 9
seals the nozzle of the water pipe 7, and timing is performed after all the active control devices for
soil water content feedback are buried in the soil layer. After 20 to 30 minutes, add water to the
drip irrigation branch pipe 11. Due to the pre-irrigation, in order to facilitate the investigation, the
driven waterway control device will close the nozzle of the water pipe 7 after 20min-30min. If the
driven waterway control device leaks, it means there is a problem with the device here, and it can
be overhauled separately. When the soil moisture content around the peach tree trunk drops below
%, the water-swelling rubber shrinks, and the valve plate 9 of the driven waterway control
device will move under the assistance of its own gravity and spring, the waterway would be opened
to irrigate the peach trees.
The water content of the soil directly feeds back to the control device that performs drip
irrigation according to the fruit trees' demand for soil water content. The device directly controls
the opening and closing of the drip irrigation waterway through the mechanical structure. This
method for drip irrigation can be used for drip irrigation in all kinds of orchards, especially in the
field or in experimental areas lacking power resources.
Finally, it should be noted that the above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, it is still for those skilled in the art. The technical solutions described in the foregoing embodiments may be modified, or some of the technical features may be equivalently replaced. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
