Description

Plastic irrigation system

For the processing and cultivation of ground ν soil, depending on its type and structure, 3 fac goals more or less decisive:

the nutrient supply,

the humidity,

the crumb structure.

Only when these parameters are in harmony is there a specific flourishing of Plants to be expected.

In order to ensure the nutrient supply of a soil, one generally proceeds today so that periodically - from time to time - fertilizers in the form of Powders, granules or solutions can be applied. These fertilizers are then gradually used by the reabsorbed plants that thrive on the ground.

In order to regenerate the moisture balance of a soil or to guarantee permanent moisture , one makes use of the possibility of irrigation from the outside or the water supply via pipe systems · Prevent effectively.

The crumb structure of a soil, on the other hand, becomes successful by introducing Schaunistoff flakes or foam films are guaranteed, as they loosen up the heavy soil, which tends to become coarse "caked" cause.

All of these described technical or auxiliary means are carried out or used to a large extent. They are doing well in developed countries as well as in so-called developing countries; however, they are still in need of improvement.

For example, it is associated with a lot of work if the fertilization of a soil is periodic he follows. Foam flakes are also used for structural improvement a cultivated clay soil, but not, for example, for uncultivated soil Sandy soil. Schautnfolieri that are suitable for all types of Suitable soil have the disadvantage that they are irrigated Make water from above absolutely necessary. Also foam sheets with attached on the underside Water tanks are only suitable for use to a limited extent, for greenhouses and not against it for large areas or remote areas. Dense plastic films, such as those made of polyethylene, are also well suited for steppe soils as well as for cultivated soils. But also -s-you "do an irrigation required from above. That may be somewhat insignificant in developed countries, though a .cn an increasing water scarcity can be expected here must, in developing countries, in stone pens, deserts but these are not suitable for avoiding high water losses. - _.

Claims (2)

The innovation has set itself the task of creating a system that has the advantages of the above Devices or Metboden combined without having their disadvantages. These advantages are: simultaneous, permanent water and nutrient transport without losses occurring with only minimal work involved. This is achieved through a combined foil-foam system Plastic that can be easily prepared on the spot, even in remote, difficult terrain. This system is characterized by the following features: An endless film, for example made of polyethylene, with an oval half-diameter in cross-section ^! is endless at the lowest point, welded in a tubular shape. The welded-in tube is continuously perforated, and the volume formed by the film above this tube is equally endlessly filled with absorbent, open-pored foam. The following drawing is attached for a better overview. It means: a) the outer foil, b) the inserted perforated tube, c) the applied foam, Protection claims: i. Bev.
