Timely irrigation system
The invention relates to the technical field of water-saving irrigation, in
particular to a timely irrigation system.
Developing efficient water-saving irrigation technology is an effective way and a
fundamental way to solve the shortage of water resources in Northwest China. At
present, it is recognized that the most water-saving irrigation methods are various
forms of micro-irrigation, including Israel's above-ground drip irrigation,
underground infiltration irrigation (including micro-irrigation and trace irrigation) and
negative pressure irrigation, etc., but these micro-irrigation methods have various
technical deficiencies. 1) Drip irrigation is widely used in Israel, and the main
problems are: intermittent irrigation can not realize self-adaptive irrigation , which
requires extremely high water quality, short distance of capillary laying (50-80m),
large loss of surface evaporation and easy blockage of emitter; Surface pipe laying
affects field mechanical operations, etc. 2) Underground infiltration irrigation can
realize continuous irrigation, but can not realize self-adaptive irrigation triggered by
water demand of plant roots, and has higher requirements on water quality, which
requires a special filter device of 120-200 meshes, and the emitter is more easily
blocked, especially the root system blocks the emitter. 3) Negative pressure irrigation
is the only self-adaptive irrigation technology that can realize the touch of plant water
demand at present. However, it requires high sealing performance of emitters, and
emitters in clay pots are easy to be blocked. All emitters must be installed at the same
level. Negative pressure irrigation cannot realize long-distance water delivery. At
present, its application scope is limited to small-scale experiments or pilot-scale tests
such as potted plants and greenhouses. The above technical problems have become
bottlenecks in the development and application of traditional micro-irrigation
technologies (including drip irrigation in Israel, deep underground irrigation and
negative pressure irrigation). Theoretically speaking, the most water-saving irrigation
method is root-triggered self-adaptive irrigation. At present, the only technology that
can realize plant self-adaptive irrigation is negative pressure irrigation. However, in
large-scale application, long-distance water delivery can only be achieved by
pressurizing the capillary water delivery process. The existing negative pressure
irrigation system can not solve the contradiction between positive and negative
pressure at the same time, and can only carry out water-saving irrigation by adjusting
irrigation time, working pressure and emitter effluent flow, but it is difficult to truly
realize plant self-adaptive irrigation.
The purpose of the present invention is to provide a timely irrigation system,
which separates a long-distance positive pressure water delivery device from a
negative pressure emitter device for plant self-adaptive irrigation through a water
storage device as a medium, so as to realize an irrigation mode in which intermittent
long-distance positive pressure water delivery and plant negative pressure self
adaptive continuous irrigation coexist, and truly realize the self-adaptive irrigation in
which plant roots trigger water demand.
To achieve the above purpose, the present invention provides the following
scheme:
The invention provides a timely irrigation system: comprising a water delivery
device, at least one water storage device and at least one emitter device, wherein one
end of the water delivery device is communicated with at least one water diversion
pipeline through a water delivery pipeline, and at least one water storage device is

float valve is arranged between the water storage device and the water inlet pipe,
which is used for controlling the water level in the water storage device, and the water
delivery device is used for introducing water into the water storage device. At least

water delivery device stops supplying water. The root system of plants absorbs water
in the water storage device by capillary action through soil and permeable soil

The purpose of the present invention is to provide a timely irrigation system,
which separates a long-distance positive pressure water delivery device from a
negative pressure emitter device for plant self-adaptive irrigation through a water
storage device as a medium, thereby realizing an irrigation mode in which intermittent
long-distance positive pressure water delivery coexists with plant negative pressure
self-adaptive continuous irrigation, and truly realizing self-adaptive irrigation in
which plant roots trigger water demand.
In order to make the above objects, features and advantages of the present
invention more obvious and easy to understand, the present invention will be further
explained in detail with reference to the drawings and specific embodiments.
As shown in fig. 1- fig. 2, this embodiment provides a timely irrigation system,
which comprises a water delivery device, at least one water storage device 5 and at
least one emitter device 6. one end of the water delivery device is communicated with
at least one water diversion pipeline 4 through a water pipe 3, and at least one water
storage device 5 is communicated with each water distribution pipeline 4 through a
water inlet pipe 7. The float valve 8 is used to control the water level in the water
storage devices 5, and the water delivery devices are used to introduce water into the
water storage devices 5. Each water storage device 5 is provided with at least one
emitter device 6, which includes a permeable soil column, and plants absorb water in
the water storage devices 5 through the permeable soil column. When the timely
irrigation system of this embodiment is in use, the water storage device 5 and emitter
device 6 are placed under the root layer of plants, and water is supplied to the water
storage device 5 through the water delivery device. When the water level reaches the
position of the ball valve 8, the ball valve 8 automatically closes, and the water
delivery device stops supplying water. The root system of plants absorbs water in the
water storage device 5 by capillary action through soil and permeable soil column in
the emitter device 6. When the water level in the water storage device 5 is lower than
the position of the ball valve 8, the ball valve 8 automatically opens and the water
delivery device supplies water to the water storage device 5 again.
Specifically, in this embodiment, the water delivery device comprises a water
source and a filter 2, wherein the water source is communicated with the filter 2
through a pipeline, and the filter 2 is communicated with a water delivery pipeline 3.
A valve 1 is arranged on the pipeline between the water source and the filter 2.
In this embodiment, the water storage device 5 is a water storage tank 9, and the
cover 15 of the water storage tank 9 is provided with an exhaust pipe 12 which is
hermetically connected with the cover 15. One end of the exhaust pipe 12 extends into
the cover 15 and is located above the water level at the ball valve 8, and the other end
of the exhaust pipe 12 extends out of the ground. An oil dipstick 13 is inserted into the
exhaust pipe 12, one end of which extends into the bottom of the water storage tank 9,
and the other end of which extends out of the exhaust pipe 12. The oil dipstick 13 in
the exhaust pipe 12 can monitor the water level in the water storage tank 9 at any time.
If the water source in the water storage tank 9 is sufficient, it can keep the soil of plant
roots moist without waterlogging. If the water source in the water storage tank 9 is
insufficient, the fault can be found in time through the oil dipstick 13, and the water
storage tank 9 or the emitter device 6 can be repaired in a targeted manner without
affecting other water storage tanks 9 or emitter devices 6. The water storage tank 9
has a length of 50-100 cm, preferably 71 cm, a width of 20-50 cm, preferably 34 cm,
a height of 20-50 cm, preferably 34 cm, a wall thickness of 2-4 mm, preferably 2.5
mm, a capacity of about 70 kg, and actual water storage of about 50 kg.
In this embodiment, according to different plants, several emitter devices 6 can
be arranged in a water storage tank 9. The emitter devices 6 include irrigation pipes
which are hermetically connected with the water storage device 5. The upper ends of
the irrigation pipes are flush with the tank cover 15 or extend out of the tank cover 15.
The lower ends of the irrigation pipes are located below the water level at the ball
valve 8. The irrigation pipes include permeable soil column sections 10 and gravel
sections 11 which are sequentially arranged from top to bottom, and the permeable
soil column sections 10 are filled with permeable soil. Gravel section 11 is filled with
gravel, and the pipe wall of irrigation pipe of gravel section 11 is uniformly provided
with a plurality of small holes, and the upper opening of irrigation pipe is covered
with filter cloth 14.The diameter of the small hole is 0.5-2 mm, preferably 1mm, and
the filter cloth 14 is 200-400 mesh, preferably 300 mesh, which can prevent the root
system from entering the irrigation pipe. The diameter of gravel is 2-5 mm, preferably
3mm, and the height of gravel section 11 is 3-8 cm, preferably 5cm. In this
embodiment, the water supply rate is automatically adjusted by the soil matrix
potential, so that the plant root system absorbs soil moisture, and the soil becomes dry,
so that the permeable soil column absorbs water from the water storage tank 9 to
supplement the root layer soil by capillary action, and the water supply rate is
automatically adjusted to ensure that the plant root system grows under humid
conditions for a long time.
In this embodiment, the structure of the float valve 8 is the prior art. When the
ball float valve 8 is installed, the float in the valve cavity must be vertically downward,
and the water inlet pipe 7 is suitable for the nominal diameter of the ball float valve 8.
The float valve 8 controls the water level in the water storage tank 9. When the water
level drops, the float in the valve cavity of the float valve 8 sinks, opening the pilot
hole of the float valve 8. Under the action of water pressure in the water inlet pipe 7,
the sealing surface of the float valve 8 is opened, and water flows out from the float
valve 8 to the water storage tank 9. When the water level rises to the control line, the
float rises, and the float valve cavity is filled with water, and then the float valve 8
closes to stop water supply.
In this embodiment, each water storage device 5 and the emitter device 6 are
embedded into a whole, and are located under the root layer of the plant together. The
water source is communicated with several water storage devices 5 (including the
emitter devices 6) through the water delivery pipeline 3, and a proper amount of water
is always stored in the water storage devices 5, which is slowly and continuously
transported upward by the emitter devices 6 for absorption by the plant roots. After
the water level of the water storage tank 9 drops to a certain extent, the ball valve 8
automatically opens, and water can be delivered to the water storage tank 9 through
the water delivery device. After the water is delivered to the water level, the ball valve
8 automatically closes, and the water delivery pipeline 3 continues to deliver water to
the next water storage tank 9 and the emitter device 6. By adjusting the buried depth
of the water storage tank 9 and the height of the permeable soil column, the moisture
degree of the root layer soil can reach the best condition for plant growth, ensuring the
long-term growth of plant roots under humid conditions, and forming the best growth
environment of roots with suitable water, fertilizer, air and heat balance. The emitter
device 6 realizes negative pressure irrigation, which can reduce water leakage and
evaporation loss among trees to the maximum extent, which not only ensures the need
of plants to utilize water, but also achieves the purpose of saving irrigation water. The
timely irrigation system of this embodiment can be placed at a certain depth under the
plant tillage layer, which is simple to operate, convenient to use and widely applied,
and has more remarkable effects in irrigation of deserts, desert areas, trees and
economic forests.
The working principle of this embodiment is simple, which can avoid
unnecessary evaporation loss, save water resources, achieve the most direct irrigation
effect, truly realize positive pressure water delivery and negative pressure irrigation,
and has great practical value, which can save a large amount of water resources
without power and energy consumption. The timely irrigation system will not be
blocked under any circumstances, and can be successfully installed once, with low
maintenance cost, simple manufacturing and production process, low production cost
and very simple installation.
In this embodiment, the water quality of the water source is low, and it only
needs simple filtration (<20 mesh); Long-distance water delivery can be realized, and
the theory can reach more than 1 km by closing the ball valve 8; through the
permeable soil column, the problem that the emitter of underground drip irrigation is
easy to block is solved; through the embedding of the water storage tank 9 and the
emitter device 6, the difficult problem of sealing the low-pressure water delivery of
the negative pressure irrigation pipeline is solved; the contradiction between
intermittent water supply and continuous irrigation is solved by separating the water
storage tank 9 from the water delivery device. The 300 mesh filter cloth 14 solves the
problem that the root system blocks the emitter device 6.
Application case one
The method for planting Haloxylon ammodendron in desert is as follows:
Planting Haloxylon ammodendron seedlings, digging a pit with a depth of 70 cm,
placing a water storage device 5 and an emitter device 6 at the bottom of the pit,
burying 5-10 cm of soil, placing the Haloxylon ammodendron seedlings obliquely on
the top, digging some wet soil from the other side to cover the root system of
Haloxylon ammodendron, putting the seedlings in layers and burying the soil layer by
layer, finally carrying out compaction treatment to avoid air drying, pouring enough
water for the first time, close the valve 1 on the water delivery pipeline 3, and then
inject water when the water in the water storage tank 9 is about to be consumed, and
inject water into the water storage tank 9 once every three months to realize
intermittent water injection into the water storage tank 9, thus avoiding excessive
energy consumption; the valve 1 can also be kept open as required, and the water
storage tank 9 can be continuously and automatically filled with water under the
control of the float valve 8. Irrigation with timely irrigation system can keep the root
zone in a wet state all the time and effectively improve the survival rate of Haloxylon
ammodendron. And correspondingly, when the prior art is adopted for irrigation,
water needs to be poured once every two days, and in terms of the growth of
Haloxylon ammodendron, the timely irrigation system adopted in this embodiment is
obviously better than the prior art..
Application Case 2
Fruit trees are planted in desert, and the timely irrigation system of this
embodiment is buried in the root area of seedling fruit trees to carry out water-saving
irrigation, which saves irrigation time and labor intensity, is beneficial to the
absorption and transportation of water and nutrients by the root system of fruit tree
seedlings, and promotes the growth of seedlings.

implementation of the present invention, and the explanations of the above
embodiments are only used to help understand the method of the present invention
and its core ideas; at the same time, according to the idea of the present invention,
there will be some changes in the specific implementation and application scope for
the ordinary technicians in the field. To sum up, the contents of this specification
should not be construed as limiting the present invention.
