The pond with his hands
Today, many garden and suburban areas dug ponds. And not only fire ponds, and ornamental ponds.
The pond at the cottage, in addition to the practical value (supply of water for irrigation or for poganyj needs) and has an important aesthetic value. In addition, the pond with his own hands made, and there will be a subject of pride of owners and envy of neighbors. Garden pond is not difficult. It is important only to observe some rules and to follow this interesting subject – the pond with their hands.
Unlike earth, where all the time something changes: planted new plants, are made of ridges, flower beds, Alpine slides, etc. to the pond does not reach the hands, he lives his life. And how does she live? He, like soil, have their indicators, their “pests”, “weeds” and “plants”.
That’s about them, about indicators, and how they can change and improve, and we’ll talk. What would a pond with his own hands made please you for many years.
Key features garden pond:
Thus, the characteristics of the water in the pond include:
– oxygen saturation
– saturation with carbon dioxide and nutrients
– the temperature.
The acidity is determined by the level of pH and pH depends largely on the content in the pond of lime, phosphates and nitrates, as well as processes of decay. A neutral pH level is 7, that is, at lower water is considered acidic, while higher, respectively, alkaline. Most of the plants and fishes satisfied neutral environment (pH=6,5–7,5). The stiffness associated with the content in water of dissolved salts of calcium and magnesium. And if you have in the pond are actively developing filamentous algae which form slime, then water is hard. Soft rainwater passing through limestone rock becomes too hard.
To correct the hardness, soften water capable of submerged pond plants: pondweed, hornworts, they absorb the salt. Furthermore, it is known that only a handful of alder cones can during the day to make soft 50 litres of hard water.
Now that affects the oxygen content in the water. First, the temperature: the colder the water, the more oxygen. Flowing into the pond streams saturate the water with oxygen. The number of plants in the pond through which water is saturated with oxygen. Keep in mind that deciduous leaves, dead stems, once in the pond, decomposition consume oxygen.
Especially a lot of oxygen is consumed for oxidation of organic substances, which gradually get mineralized (transformed into simple compounds carbon dioxide, water, salts of ammonia and other salts). The oxidation and mineralization of organic substances takes place with the bacteria.
In winter the oxygen in the water falls through the hole in the ice or through the dry stems of riparian plants (cattails, reeds, cane, rush, iris, calamus), or in locations in the water large stones.
The next indicator saturation with carbon dioxide and nutrients necessary for plant development and life, when they lack they can even hurt. Carbon dioxide is produced by various living beings of the reservoir, as it is formed during the oxidation of organic substances, but too much is dangerous for fish, as it violates their breath.
If the water is too rich in nutrients, the pond begins to “bloom” in the water was the rapid development of single-celled algae.
If nutrients are few, do not grow plants such as water lilies, cattails, reeds. With excess nutrients in the pond remarkably quickly deal willow with narrow leaves, they can be planted along the pond.
The temperature of the water. In cool water less breed mosquito larvae, rarely observed “bloom”. To the surface layer was cold, the required mixing water, which provides the population of pond fish, frogs, and ducks. Cooling water (and thus increase the content of oxygen in it) will also help the plants floating on the surface (duckweed, vodokras, Lily pads) and shading due to trees growing nearby.
It is clear that the water level in the pond may change to decrease. Try to keep in the pond got more than soft rain water, from water to grow filamentous algae.
It is very important during the first filling of the pond to pour water from a reservoir with an established ecosystem in the pond hit the right microorganisms. Pour water as accurately as possible, so as not climbed the soil from the bottom.
