DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a trough intended for the irrigation and moistening of earth in tree plantations and the like, in dry regions requiring soil irrigation to enable trees and plants to develop.
The aim of the present invention is to provide a trough of simple construction intended to make it easier to plant trees, plants and the like, and to allow the said trees, plants and the like to develop under difficult soil conditions, especially where soils are irrigated artificially.
Another aim of the present invention consists in placing the tree, the plant or the like in good soil moisture conditions while relying on an irrigation which is as low as possible.
Another aim of the present invention consists in reducing the quantities of irrigation water which are not used and which are lost in the arid soil.
In accordance with the present invention, the irrigation trough has side walls made of a water-permeable material and whose bottom is waterproofed.
The trough is preferably essentially parallelepipedal in shape and is covered with a waterproofed lid comprising at least one entry opening and/or a coupling for a feed conduit.
The troughs of the present invention are intended to be embedded in the soil to be irrigated and can contain water or a fertilizer solution. The liquid can exude through the permeable side walls and moisten the surrounding soil.
According to a preferred embodiment of the present invention, the leakproof and impervious lid preventing any loss of water by evaporation also comprises a discharge opening and/or a coupling for a discharge conduit. In this way, it is possible to connect a number of troughs in series, at a certain distance from each other, so as to moisten and irrigate the soil as uniformly as possible.
The trough is advantageously slightly trapezoidal in cross-section, with the bottom acting as the long base of the trapezium. A moistening and/or irrigation of the soil which is as uniform as possible is thus obtained.
It has been found, in fact, that, when the trough is interred, the upper crust of the earth is not moistened substantially but remains dry and forms an insulation against the evaporation of water from the moistened lower layers. It should be noted that this forms a control of the moistening and of the loss of water.
The use of a leakproof bottom prevents the loss of water by diffusion downwards, where the water is not necessary. The side parts diffuse water into the earth, where it is available to the roots. Downward diffusion of water takes place in the lateral earth, enabling the water to be made available to deep roots.
According to an alternative form of the invention, the said trough has an outer wall and an inner wall at a distance from the said outer wall and connected to the latter at the bottom so as to form with the latter a peripheral volume intended to contain water, the central volume delimited by the inner wall being open at the bottom and at the top and being intended to contain the earth as well as a tree, a plant and the like.
According to a first alternative form of the embodiment of the present invention, the outer wall is essentially waterproof.
According to another form of embodiment in accordance with the present invention, the outer wall is also water-permeable.
The trough of the present invention may be advantageously embedded in the soil. The tree, the plant and the like is introduced into the earth filling the central volume delimited by the inner wall and the peripheral volume closed at the bottom delimited by the inner wall and by the outer wall is fed with water. In view of the use of a permeable inner wall, the water can diffuse through the inner wall to supply water to the roots of the tree or of the plant and the like, which line the said wall.
When the plant has developed sufficiently, the roots move on through the lower opening of the volume delimited by the inner wall. The water which has not been absorbed by the upper roots diffuses into the soil and thus produces good irrigation.
According to an advantageous embodimen
