Systems of subirrigation

Abstract

This underground irrigation system comprises the following steps: embedding a porous pipe 22 into the ground of the fields (cultivation areas 13), setting up a water level setting tool 31 on the lower-stream side of the porous pipe, regulating a drainage water level by the water level setting tool to set the water level of the field, embedding an underground water supply pipe 41 for supplying water for use from a water supply channel 14 into the ground of the field, connecting the underground water supply pipe 41 with the porous pipe 22 at the drainage side of the porous pipe to supply the water for use from the underground water supply pipe to the porous pipe.

Description

technical field [0001] The present invention relates to an underground irrigation system. Specifically, it relates to an underground irrigation system for setting the ground water level or surface water level of a field by adjusting the drainage water level from a perforated pipe buried in the ground. Background technique [0002] Underground irrigation, which has been continuously carried out in recent years, is to adjust the groundwater level of the field during cultivation, to replenish water through capillary phenomena, and to increase the yield of crops by adjusting the groundwater level to a water level suitable for crops. This kind of underground irrigation is usually buried in the ground of the field by the underdrain drainpipe that is made of perforated pipes, the remaining groundwater in the ground is discharged into the drainage channel, and the underdrain drainpipe is also used to supplement the insufficient water (for example, refer to Page 2 and figure 1 , f...

Problems solved by technology

In addition, when the supplied water contains a large amount of foreign matter such as garbage or sand, these foreign matters may accumulate in the drain pipe of the underdrain and hinder the water flow performance.
