A capillary irrigation device in which flat plates are closely laminated and combined with a tube body

Abstract

A capillary subirrigator (8) with tightly stacked flat-boards and a combined pipe. At least two smooth-surfaced rigid flat-board materials (1, 2) are tightly stacked to form a narrow gap and is enclosed with a water-impermeable material outside, where only narrow gaps at two ends on the top and bottom are not enclosed, so as to form a narrow gap channel (3). The narrow gap channel (3) is combined to a segment of pipe (4) in a "T"-form. An end of the narrow gap channel (3) is placed inside the pipe (4), and the other end is placed outside the pipe (4), so as to form the capillary subirrigator (8). The capillary subirrigator (8) can implement a function of local irrigation of water from the pipe (4) buried in soil to soil in an active layer of the major root system of a plant. The narrow gap confines intrusion of the root system of a plant. The use of capillary action avoids blockage in the capillary subirrigator (8).

Description

technical field [0001] The invention relates to a capillary irrigator, in particular to a capillary irrigator in which flat plates are closely laminated and combined with a tube body, which can realize partial irrigation of water from the tube body buried in the soil to the soil in the active layer of the main root system of the plant. function. Background technique [0002] Infiltration irrigation is a kind of underground irrigation technology, which is one of the most advanced facility irrigation technologies in the world today. It embeds the tubular irrigator in the active layer of the main root system of the crop, and the surrounding of the infiltration irrigation pipe is in contact with the soil. The irrigation pipe slowly seeps out, enters the soil pores and immediately forms soil water after docking, which eliminates the dry-wet cycle of the soil, reduces the water stress of the crops, and has the advantages of saving water, saving energy and increasing production. ...

Problems solved by technology

[0006] In order to overcome the defect that the irrigation pipe is prone to blockage, the present invention designs a capillary irrigation device, Figure 1 is the front view of the capillary irrigation device, Figure 2 is A-A section of Figure 1, Figure 3 is Figure 1, characterized in that at least one piece of smooth and hard flat material (1) is closely stacked with another piece of smooth and hard flat material (2) of the same shape to form a narrow gap, and the outside is surrounded by impermeable materials, only Leave the narrow gaps at the upper and lower ends unclosed to form a narrow gap channel (3). The narrow gap channel is combined with a section of the tube body (4) in a "T" shape. One end of the narrow gap channel is placed in the tube body and the other end is placed in the tube body. in vitro
