every all install the second connecting pipe on the lateral wall of semi-closed irrigation section of thick bamboo, every hydraulic spring all installs on the interior diapire of semi-closed irrigation section of thick bamboo, every equal slidable mounting has water pressure board and pressure release board in the semi-closed irrigation section of thick bamboo, and the lower wall of water pressure board and hydraulic spring's upper end fixed connection, install the connecting rod jointly between water pressure board and the pressure release board, a plurality of pressure release holes have been seted up on the pressure release board, the sealed lid in upper end of semi-closed irrigation section of thick bamboo is equipped with mud guard, a plurality of holes of permeating water have been seted up on the mud guard, a plurality of needles of sealing are installed with a plurality of corresponding positions in hole of permeating water to the upper surface of pressure release board.

Preferably, the irrigation pipe is buried in soil, and the pre-buried depths of the irrigation pipe and the semi-closed irrigation cylinders are both more than or equal to 60 cm.

Preferably, the connection position of the second connecting pipe and the semi-closed irrigation cylinder is positioned between the water pressure plate and the pressure relief plate.

Preferably, the diameter of the sealing needle is equal to that of the water permeable hole, and the length of the sealing needle is equal to that of the compression length of the hydraulic spring and is smaller than the distance from the pressure relief plate to the second connecting pipe.

The invention has the following beneficial effects:

1. through a plurality of semi-closed irrigation section of thick bamboo pre-buried below farmland soil top layer for irrigation water can moisten soil gradually, thereby reach the purpose of supplying moisture for crops, it is extravagant to have avoided a large amount of irrigation water to be located the evaporation above the soil surface, has reduced the irrigation number of times, has reduced the labour simultaneously and has practiced thrift the water resource, has reduced the influence of irrigation to river ecology.

2. The rivers get into semi-closed irrigation barrel through the second connecting pipe make rivers pressure extrusion water pressure board and see through pressure release hole extrusion mud guard, because mud guard is fixed, and the hole of permeating water is sealed the needle and is blockked up, then the water pressure board is promoted downstream and compression hydraulic spring by rivers pressure, then make pressure release board and needle of sealing downstream through the connecting rod, make the needle of sealing extract the hole of permeating water, make rivers spill over semi-closed irrigation barrel from the hole of permeating water and moisten the moisturizing to soil, seal the needle and can avoid soil to get into semi-closed irrigation barrel and avoid earth to block up the hole of permeating water, and the hole of permeating water can reduce water pressure impulsive force, avoid influencing the soil structure, the reliability and the stability of irrigation have been increased.

In conclusion, the semi-closed irrigation cylinder and the irrigation pipe are pre-embedded below the soil, so that soil is moistened and supplemented, evaporation capacity and labor force are reduced, water resources are saved, the influence of agricultural irrigation on river ecology is reduced, the semi-closed irrigation cylinder is prevented from being blocked by soil through the needle sealing, and the influence on soil structure caused by water flow impacting the soil is avoided through the water permeable holes.
