Perlschläuche

The care of plants requires a lot of knowledge, skill and above all the right growing conditions. While too few nutrients, lack of light or a little too low temperatures can be weathered quite well for a long time, water shortage or water surplus is fatal for most plants within a very short time. That is why it is indispensable for a successful care to irrigate plants adequately. While in home use a small watering CanIn order to provide plants with the right amount of water and this usually works very effectively by eye, more effective irrigation methods are needed in large beds. Depending on the plants you care for, you need the right irrigation method to ensure adequate water supply. Many plants are not overly demanding, especially in the garden when the soil is very well drained and it is possible to plant the flower beds with one water hosebut this is not always the case. In many cases, plants are sensitive to wet leaves, need especially in the midday heat, when the pouring from above forbids, especially a lot of water or make for other reasons a more effective and more targeted irrigationnecessary. Such irrigation system provide drip, slot or perl hoses.

Structure and function of a Perschlauchs

A Perschlauch is in principle very simply constructed. It consists of a connecting piece with which the hose can be connected to a water pipe. Following the connector, there is a pressure reducer. While the working pressure of the hose should be between about 3 and 10 bar, this pressure would destroy the actual hose. The effectively fed into the hose water pressure is just under 2 bar.
Following the pressure reducer is already the actual Pearl Hose , This usually consists of recycled and recycled rubber. This is extremely porous and allows the water contained therein to leak or pearl over the entire surface. Since the pore size is very small and therefore allows a very uniform distribution of the cavities over the entire surface of the hose, an equally uniform irrigation of the soil is guaranteed. When watering with the Pearl Hose The water is released by the pressure in very small quantities, as the name implies in the form of individual drops to the outside. Since the soil is not overloaded by this evenly small amount of water, the water can be absorbed effectively, spread in the wider environment of the hose and is thus available to the plants in a constant amount.

History of the pearl tube

The the Pearl Hose underlying irrigation method is called drip irrigation. A first mention of drip irrigation can be found in Fan Sheng-Chih Shu from the 1st century BC. In China. However, as a porous material clay was used and used in the form of water-filled pots, as is still done today with Tonkegeln. This method was maintained for centuries until finally 1860 German scientists carried out experiments for further development. This clay pipes were used, but were first laid underground. Here, too, the water seeped through the highly porous material into the ground. However, clay has the disadvantage that it is chemically active. It acts as an ion exchange filter, which filters out many desirable constituents, such as minerals and other nutrients, from the water. Therefore, while sound provides a very even supply of water, long-term irrigation with this method provides the same riska nutrient deficiency or at least an unbalanced supply of nutrients that ultimately actually negatively impacts plant growth. At the same time, clay is a very fine-pored material. After prolonged use for irrigation and continuous filtration of nutrient salts from the water, these are deposited in the pores so strong until they clog and a uniform water supply is no longer guaranteed. As a result, in the next few decades worked on the further development, until finally known today Pearl Hose was developed. Since this is made of rubber, it is chemically almost completely inactive and does not remove nutrients from the water. Thus, a high-quality and perfect irrigation is ensured even over many years.

Fields of application for hoses

Hoses are laid underground to direct water to where it is needed – to the plant roots. Since the active water-bearing portion of the root is near the top rather than the near-surface base, irrigation from above is ineffective. Especially on hot summer days, part of the water evaporates before entering the earthseeps. Another part of the water penetrates only superficially into the earth and also evaporates again unused. Perl hoses are therefore usually laid underground to deliver the water directly at the right depth and to provide the active part of the root. Since the water is low due to the low, evenly Pearl Hose it is possible to irrigate large quantities of land in the ground without discharging into the groundwater or evaporating at the surface. This makes the pearl hose ideal not only for irrigating beds, but also for one raceto provide evenly with water and, above all, to get green all over the summer.

Advantages and disadvantages of Perlschläuchen

Hoses offer the advantage to bring water very targeted to the roots of the plants. As a result, losses due to evaporation are avoided and too much watering and the resulting infiltration of the water into deep layers of soil are prevented. Because the beaded tube remains permanently in the soil, it can continuously deliver water to the soil, and in exactly the same quantities as the irrigated plants are able to utilize. As a result, an extremely efficient and targeted irrigation can be realized which helps to significantly reduce water consumption. At the same time it is also possible to water plants in the middle of the day, especially when their water consumption is highest. When watering from above, drops of water remain on the leaves, bundle the sunlight and can damage the plants through sunburn. The reduced evaporation at the earth’s surface also helps to prevent salting of the soil. If watering from above, the water evaporates again, but all minerals, nutrients, but especially lime remain in the soil. These substances are flushed deeper in a rain shower in high concentration and can then damage the roots. Another advantage of Perlschläuchen is that thanks to the pressure reducer to non-adjustable water pumpscan be connected. This makes it possible for example water in one rain barrelWith liquid fertilizerand use a water pump to feed this fertilizer solution into the hose. This not only provides the plants with efficient water, but also nutrients. Nevertheless, the pearl hose has some disadvantages. First of all, the laying requires a lot of work and is hardly possible without damage to the plants in the case of already completed beds. Particularly deep-rooted plants require deeply buried pearl hoses. Another disadvantage concerns the filtering of nutrients. Although the rubber binds no nutrients as it does clay, however, deposited here in a purely physical way also lime in the pores and clogs it sometime. Ultimately, rubber is a very weather-resistant material. This significantly increases the life of the hoses, but each gum will become porous and cracked over time. The complete removal of all residues can be difficult with unknown consequences for the environment.
