Atonogeton extended (Aponogeton elongatus) – aquarium plant belonging to Aponogeton (Aponogeton), Aponogeton family (Aponogetonaceae).
Atonogeton extended – very beautiful and large enough water plant with long bright green slightly wavy leaves that reach a length of 1.5 m. It is recommended to contain a large body of water. Aquarists this plant is extremely rare.
Seasonality of growth is poorly expressed: in the winter-spring period plant growth slows down, but the main part of the leaves remains.
Atonogeton extended the best thing keep in a tropical aquarium with water temperature from 24 to 26 ° C. Lowering the temperature of the water leads to a slowdown, and then to stop the growth. During the rest period, an elevated temperature (above 26 ° C) leads to depletion of the plant.
Optimum water parameters for content aponogeton elongated: hardness 2-6 ° (parameter increase up to 12 ° is possible), pH 6.5-7.5. Since the plant prefers fresh water, the indispensable condition is a weekly water change up to 25% of the volume of the aquarium. Atonogeton extended has a well-developed root system.
Well-silted coarse and medium pebbles will be suitable as soil. In the fresh soil you need to add clay or a mixture of peat and clay. The thickness of the soil layer should be at least 7 cm.
During the period of rapid growth (summer and autumn) it is recommended to feed the plant with complex mineral fertilizers, with a predominance of nitrogen. Atonogeton extended loves bright lighting and preferably natural.
As an artificial light suitable fluorescent lamps type LB, with a power of 0.4 W per liter of volume aquarium. Incandescent bulbs can be used as an additional backlight. If the young leaves of the plant have a reddish-brown color, this means that apono-geton has enough light.
Duration of daylight should be 12-14 hours. Slightly reduce the length of daylight is possible by increasing its light intensity.
Breeding Atonogetona extended can occur as a vegetative method, and through the seeds. Vegetative reproduction: At the end of the rest period, the elongated rhizome of the plant is divided into 2-4 parts with such condition that growth buds remain on each part. Pieces of rhizome are planted in lightly-silted soil, which is recommended to add charcoal.
From each piece of rhizome a new plant is developed. Propagation by seeds: if the plant grows in favorable conditions, then in the fall it starts flowering.
Spike inflorescences are cross-pollinated. The resulting seeds are planted in a separate aquarium with silted sand.
The water level should not be high. Seeds germinate at a temperature of 26-28 ° C. and intense lighting. As young plants grow, the water level in aquarium increase.
After 3-4 leaves have been formed, the plant can be transplanted into a common aquarium.
