Embodiment 1

[0013] Example 1, see figure 1 , select the water tank as the water source, and process it into a water supply tank 1, a water delivery pipe 2 and a plastic pipe 10; the top of the water supply tank 1 has a water inlet 5, and a detachable sealing plug 9 is arranged on the water inlet 5, and the pressure is installed in the water supply tank 1. Adjusting pipe 8, the lower end of pressure regulating pipe 8 is located below the water surface in the water supply tank 1, and a water outlet 7 with a control switch 6 is opened at the bottom of the water supply tank 1; there is a water outlet 4 on the water delivery pipe 2; the diameter of the plastic pipe 10 is 10-30cm, the length is 15-85cm, the upper and lower ends of the plastic pipe 10 are not closed, the water seepage hole 12 is opened on the peripheral wall of the plastic pipe 10, the water seepage hole 12 is located at the peripheral wall position below the upper port 10cm of the plastic pipe 10, and the hole diameter is 1 -3c...

Embodiment 2

[0014] Example 2, see figure 2 , with embodiment 1, the difference is: take the drip irrigation fruit tree as an example, open the annular sand ditch around the fruit tree trunk between the trunk base 25-75cm, the sand ditch width is between 10-30cm, and the depth is between 15-50cm In between, the surrounding wall in the range of 0-10cm on the upper part of the sand ditch is sealed by an impermeable plastic plate 14, and the inside is filled with coarse sand to form an annular sprinkler 3, and an annular water delivery pipe 2 is placed on the coarse sand of the sand ditch, and one end of the water delivery pipe 2 is connected to the water source Connect, one end opening is water outlet hole 4.

Embodiment 3

[0015] Example 3, see image 3 , for the smaller situation of crop spacing (generally less than 50cm), with embodiment 2, the difference is that the sand ditch is linear, and the water delivery pipe 2 is directly laid on the top of the sprinkler 3 formed by the sand ditch, and the water delivery pipe 2 One end is connected with a water source, and the upper opening is a water outlet hole 4 .

[0016] A kind of indirect underground drip irrigation system according to the present invention uses the water source as the water supply tank, and when in use, the water supply tank is placed flat on the ground at the head of the row of pre-irrigated crops. Lay horizontally on the sand ditch, and for the situation of embodiment 2, the water delivery pipe is laid horizontally outside the sand ditch along the crop row. When irrigating, first turn off the control switch on the water outlet, add water to the water supply tank from the water inlet, after adding water to the predetermined po...

Abstract

The invention relates to an indirect underground trickle irrigation system which comprises a water source and a water transmitting pipe (2), wherein a water outlet (4) is arranged on the water transmitting pipe (2). The indirect underground trickle irrigation system is characterized in that the lower part of the water source is provided with a water nozzle (7) with a control switch (6); the watertransmitting pipe (2) is connected with the water source by the water nozzle (7), and an irrigator (3) is embedded into the soil below the water outlet (4) on the water transmitting pipe (2). The system prevents soil evaporation loss among crops and improves the utilization ratio of water; the water transmitting pipe is positioned above the earth surface, thereby preventing the blockage of a rootsystem; and the invention has simple structure and convenient use, management and maintenance, saves labor, can dissolve fertilizer into water to carry out fertilizer water irrigation and improve theutilization efficiency of fertilizer, is particularly suitable for the viscous soil with worse water permeable ability in a drought and water lacking area and has better effect on an orchard and vegetables of a sunlight green house and a big house.

Description

Technical field: [0001] The invention relates to the technical field of agricultural irrigation, in particular to an indirect underground drip irrigation system. Background technique: [0002] Drip irrigation is one of the most advanced irrigation technologies in the world. Drip irrigation can regulate soil moisture very precisely in time and space, and can create and control soil moisture conditions that promote crop growth or control crop growth as needed, so that crop moisture conditions Always in the optimal state, avoiding the periodic excessive water and water deficit caused by other irrigation methods, and can effectively reduce deep seepage, so drip irrigation can significantly improve crop yield and water use efficiency . Drip irrigation is not only used for crops with high economic value such as horticultural flowers, vegetables and fruit trees. With the occurrence of global fresh water shortage, drip irrigation is gradually used for field crops such as cotton and...
