Description

[0001] The invention relates to a water guiding device.

[0002] In particular, it also relates to a storage device, storage control device and a method for supplying long-term water to trees.

[0003] Devices for watering trees at root depth are known. These devices consist of a water-carrying pipe laid underground with holes and / or slots for water outlet, or a cylindrical, water-permeable body inserted vertically or diagonally into the ground. This is intended to allow the water introduced into the device to reach the roots directly. These devices are designed differently and prevent the holes or slots from becoming clogged by creeping roots.

[0004] The object of the invention is therefore to improve the state of the art and, in particular, to propose a device for subsurface supply, i.e., subterranean supply, such as irrigation of tree roots, especially of existing trees in primarily urban areas. This device is simple to construct and manufacture, requires little space, and guarantees cost-effective subsurface installation in urban areas without damaging the tree roots. It also loosens the root-permeable space, promotes mycorrhiza, provides deep irrigation and nutrients, and encourages the roots to creep into openings. This should also be achieved in particular in areas where trees have only a small water-absorbing area around their trunk and are otherwise surrounded by a sealed surface, such as street trees in cities.

[0005] The problem is solved by the claims.

[0006] The subject of the invention is a water conducting device which has a cylinder whose longitudinal axis is at least twice as long as the linear mass of its diameter, wherein the cylinder surface has openings and the cylinder interior has an open-pored, water-conducting and water-storing substance, such as preferably biochar, wherein the cylinder preferably has openings on its longitudinal axis surface in a ratio of openings to closed area of ​​at least 1:1, 1:2, 1:3 and 1:4.

[0007] The longitudinal axis of the cylinder is at least 2 times as long as the linear dimensions of its diameter, i.e. 2 times as long as the linear dimensions of its diameter, that is, if the diameter is 10 cm, its longitudinal axis is at least 20 cm.

[0017] The cylinder according to the invention preferably has an adapter at one end, with which it can be connected to another cylinder according to the invention. The adapter can preferably be designed as a screw adapter with an external thread at one end and an internal thread at the other end, a bayonet adapter, or a plug-in adapter.

[0018] The cylinder is preferably permeable to diffusion at its ends, i.e. it has a water vapor-permeable, water-permeable cover, such as preferably a grid or a fabric.

[0019] The cylinder preferably comprises a water-conducting, preferably permanently open-pored, water-conducting, and water-storing substance, preferably an organic substance such as biochar, terra preta, leonardite, polyacrylamide, or preferably an inorganic substance such as diatomaceous earth, with biochar being particularly preferred. Open-pored means that cavities, preferably interconnected caverns, are formed between the components of the permanently open-pored substance, i.e., cavities, or caverns, with a wall distance of 0.5, 1, 2, 3, 4, 5, 6, 7, 8, to 9 mm.

[0020] Open-pored means that water can be slowly conducted through the substance, so that roots can penetrate into the open-pored substance and come into contact with water.

[0021] Preferably: with the proviso that the water-conducting substance is not an artificial synthetic polymer, such as a precipitation polymer.

[0022] Biochar, preferably from beechwood, is produced under an atmosphere-free atmosphere at temperatures between 380 °C and 1000 °C (see pyrolysis). Under these process conditions, primarily water is separated, producing biochar, synthesis gas, and heat.

[0023] Biochar has been produced in charcoal kilns since the beginning of the Iron Age. Wood was usually used as the raw material, hence the term "charcoal." This traditional process results in relatively low coal yields, and the pyrolysis gases escape unused into the atmosphere.

[0024] Polyacrylamide can be produced from acrylamide in aqueous solution by radical polymerization. The reaction can be initiated, for example, by ammonium persulfate (APS) as a radical initiator and catalyzed by tetramethylethylenediamine (TEMED).

[0025] Diatomaceous earth consists mainly of the shells of fossil diatoms, which consist mainly of amorphous silicon dioxide.

[0026] Terra preta (Portuguese for "black earth") or terra preta de indio ("black Indian earth") is the name given to a fertile anthropogenic soil found in the Amazon basin, specifically a pretic anthrosol. The soil consists of a mixture of charcoal, biochar, manure, and compost, interspersed with pottery shards and occasionally bones and fish bones.

[0027] Due to its color and the amount of pyrogenic carbon, Terra Preta, the “black earth,” is also called the Indian black earth of the Amazon, but from a soil science perspective, it is not black earth.

[0028] Leonardite is a soft, waxy, and translucent mineraloid that dissolves easily in alkalis. As an oxidation product of lignite, it is found in near-surface brown coal layers.

[0029] Leonardite is rich in humic acids (up to 90

[0030] In another embodiment, the cylinder can also be connected directly to a water supply, but this is not necessary to solve the problem underlying the invention.

[0031] A further object is the planting of plants, preferably trees, wherein the device according to the invention is arranged underground radially around the tree to be irrigated. The device according to the invention is preferably arranged underground perpendicular to the surface, so that the uppermost part of the cylinder is preferably arranged with the turf on the surface, so that the cylinder which is open at the top is flush with the ground surface. This is preferably done within the canopy area, wherein preferably 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 of the devices according to the invention are each arranged around a plant, such as a tree, depending on how large and strong the tree is, whereby the greater the number of devices according to the invention are arranged, the better. However, this can also be limited by the cost of the devices according to the invention.

[0032] A further subject matter is a method for supplying plants, such as trees, wherein at least one device according to the invention is arranged underground radially around the tree to be irrigated. The device according to the invention is preferably arranged underground perpendicular to the surface such that the uppermost part of the cylinder is preferably arranged with the turf at the surface, so that the cylinder, which is open at the top, is flush with the ground surface. This is preferably done within the canopy area, wherein preferably 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 of the devices according to the invention are each arranged around a plant, such as a tree, depending on how large and strong the tree is, whereby the greater the number of devices according to the invention that are arranged, the better. However, this can also be limited by the cost of the devices according to the invention.

[0033] The advantage of the device according to the invention is that it surprisingly loosens the rootable space, promotes mycorrhiza, and provides deep irrigation and nutrients. This can also be achieved in areas where trees have only a small water-absorbing area around their trunk and are otherwise surrounded by a sealed surface, such as street trees in cities. This increases the pore structure and surprisingly leads to an increase in root mass. Figures Fig. 1 Fig. 1 shows a side view of the cylinder 1 according to the invention with its openings 2 and the water vapor permeable, water permeable covers 3 at the two ends of the cylinder, such as preferably a grid, a fabric. Fig. 2 Fig. 2 shows a plan view of the water vapor permeable, water permeable covers 3 with their mainly elongated openings 4.
