Capillary irrigator consisting of tightly stacked flat plates and tube body

Abstract

The invention discloses a capillary irrigator consisting of tightly stacked flat plates and a tube body. According to a physical phenomenon that water in a narrow slit is lifted under the action of capillary acting force. The narrow slit is formed by tightly stacking at least two smooth hard flat plate materials; a non-water-permeable material covers the periphery of the narrow slit, and only the upper end and the lower end of the narrow slit are not closed, so that a narrow slit channel is formed; the narrow slit channel is combined with a section of the tube body in a T-shaped manner; and one end of the narrow slit channel is arranged in the tube body, and the other end of the narrow slit channel is arranged outside the tube body, so that the capillary irrigator is formed. A function of locally irrigating water from the tube body buried in the soil to the soil of a main root active layer of a plant is realized; the root of the plant can be prevented from invading through the narrow slit; and under the action of the capillarity acting force, the capillary irrigator can be prevented from being blocked.

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
