Atonogeton ulvovidny (Aponogeton ulvaceus) – aquarium plant, belonging to Aponogeton (Aponogeton), Aponogeton family (Aponogetonaceae).
Atonogeton ulvovidny come from the island of Madagascar. These plants grow both in stagnant water and in fast-flowing reservoirs.
You can meet this view at a depth of 80 cm, in sunny and shady places at an altitude of up to 1,250 meters above sea level.
Leaves apongeton ulvovidnogo fairly wide, oblong, large, light green color with a distinct manifestation of the pattern of veins in the form of a grid, planted on long cuttings. AT aquarium can grow up to 50-70 cm. in length. After flowering, the plant drops foliage, while the tuber remains in the ground and “leaves away” for 2-3 months.
This process can be observed twice a year.
Atonogeton ulvovidny is recommended contain in large aquarium, positioning it along the back wall. Content of this plants will be optimal in a tropical or moderately warm water aquarium.
The most suitable water temperature is 22-26 ° С. Water hardness should not exceed 8 °.
The medium should be neutral or slightly acid. More hard water will lead to the destruction of the tender leaves of the plant. But if the water hardness is less than 1 °, the leaves of the plant will become shallow.
At the time of finding the tubers aponogeton ulvovidnogo at rest, they do not have to be taken out of the ground, but the water temperature should not exceed 22-23 ° C. Otherwise, it is better to remove the tubers. They are stored in wet sand at a temperature of less than 20 ° C for two months.
Then they are placed in an aquarium with new clean water, subject to all the necessary conditions for growth. During the growing season, it is necessary to add every week to aquarium fresh water (about a quarter of the volume of the aquarium).
Lighting should be bright. Fluorescent lamp class LB is ideal as a source of artificial lighting.
The power of such a lamp should be 0.5 W per 1 liter of water. If there is not enough light, then the leaves of the plant are strongly drawn out, losing their decorative appeal.
Light day at the time of the main growth of the plant should be 12-14 hours. Atonogeton ulvovidny not demanding on the nutritional value of the soil. If the soil is dominated by silt, the root plants can start to rot, it is more dangerous for the growing season.
It is best if the soil contains clay and peat (its content should be small). Charcoal can also be included in the composition of the soil.
The role of the substrate is not significant, but it is better to use small pebbles or coarse sand. The soil should be 4-5 cm thick and more. During the growing season it is necessary to feed the plant with a complex mineral fertilizer.
As such a fertilizer is well suited fertilizer, which consists of trace elements. If a aquarium densely populated fish, it is enough to add only trace elements.
Breeding ulpogeton ulvovidnogo occurs both vegetatively and by seed. Vegetatively this plant multiplies pretty unproductive. At the end of the rest period of the plant tuber, it can be divided into 3-4 independent parts, and they will give new shoots.
But this will happen only if the cutting points were not damaged when the tuber was cut. Otherwise, the new tubers die.
An adult plant, under all conditions of detention, repeatedly produces several spike-shaped inflorescences. Polished aponogaton ulvovidny cross method, that is, one plant is pollinated by pollen of another. In aquarium conditions, pollen is transferred using a brush with soft bristles or by touching one flower with another.
When the seeds of aponogeton ulvoid ripen, they are placed in sandy soil, to which clay and bottom sludge are added. Water in the tank with the seeds should be a little. The temperature should be in the range of 26-28 ° C.
The presence of bright light is important. In the process of how the seeds germinate water in the tank must be poured.
As soon as 3-4 leaflets are formed, seedlings need to be transplanted into the ground aquarium.
