People have long learned to use the «tips» of plants in search of water, it was urgent need not only for travel, and when selecting a location for houses and digging wells.
Modern science divides plants in relation to moisture on the three main ecological groups: hygrophytes, mesophytes and xerophytes.
The hygrophytes the higher water requirements, because they live in swamps, rivers, and lakes, wettish areas of meadows and forests, where near surface lie groundwater. Without a huge amount of water they rapidly degenerate, because I’m used to consume water «not saving». These plants possess extensive root system, but it is located at a small depth from the surface of the earth.
Hygrophytes have large succulent stems and leaves, eye-catching eye-catching colors and freshness. The presence of these plants indicates that close below the groundwater. Of the more recognizable hygrophytes can be referred to as broadleaf cattail, air plain, reed, cane forest, oleaster (maslanka), string tripartite, creeping Buttercup and other
Plants that prefer moderate hydration, minuuttia. This group includes most of the plants in our forests and fields, but in search of water, they help us will not have.
If the field grows cattail, means the water is close. In contrast, plants of the steppes and deserts can give a hint where to find water, it is only thanks to her presence they can grow and bear fruit. These plants belong to the group of xerophytes. They have longish root system, often going back to 20-30 meters. Their branches and leaves adapted to lowest evaporation of water and the reflection of the sunlight.
In the midst of xerophytes us in particular will intrigue the so-called plant-pumps (phreatophyte), which roots reach groundwater levels.
To plants, which surely survive in arid criteria, belong saxaul, camel thorn, licorice, tamarisk, jointed glasswort, chii and other
Interestingly, plants group freetoview grow not only in arid areas. These include extensively usersproperties in the middle lane willow white, oleaster, poplar, licorice naked and other Roots have ihne such longish, as in the steppe criteria, but will certainly get the location of the groundwater. Where they grow, people usually dug wells.
It is worth considering that many plants indicate not just on the availability of groundwater, and that the water is fresh and suitable for drinking. Willow, poplar, Loch, always grow over fresh water. So as not to be mistaken, is to direct attention to the presence of several plants, because certain types of well tolerate higher salinity, for example cane usual. Because next to the cane should grow cattail and cereal plants, not determine salinity.
Plants will help to find the, groundwater at minor depths. To get to the water, in this case, you can use a shovel, axe, though by what means are at hand, allowing you to dig a hole. If the water is perfectly fills a hole, you have a couple of otherpath and allow to settle.
Before use, the water should be filtered (for this fit no matter what kind of cloth and boil. Can be used for disinfection of special chemicals. A simple method is to add iodine (2 drops of 5% tincture per liter) or a few crystals of potassium permanganate.
If you find water failed, you can «see» it from plants. One of the simplest methods of obtaining drinking water from plants — collection of evaporating water. To do this, on the branch of a tree or succulent herbaceous stem wear a plastic bag, which tied up tight and leans bottom down.
Evaporating from the leaves of the water will condense on the walls of the bag and drain on its bottom. If you use multiple bags, you can collect water, sufficient to quench thirst.
