Particle-like helium (Ottelia alismo Growing area
In nature part-shaped ottelia grows in the waters of Australia, North America and Southeast Asia.
Leaves ottelii partly shaped are almost under the surface of the water, rounded in shape, large, painted in a juicy green color. In aquarium conditions content plant in length reaches 70 cm.
Planted calve in the center aquarium, its long stems take up little space, unlike the leaves, which cover a large area of water. For this reason, you need to keep the plant in a large aquarium.
Grows evenly throughout the year. Due to some difficulties in breeding, the plant is not widely spread among aquarists.
Optimal for content ottelii partly shaped is tropical aquarium, water temperature in which in the range of 24-30 ° C, but for ottely content moderately warm as well aquarium with a water temperature of 20 ° C. The parameters are best suited soft water with a slightly acid or neutral reaction. Leaves ottely tender and fragile, in hard water they just begin to disintegrate.
The same happens with the appearance of turbidity or in the old water. Therefore, it is necessary to regularly replace water.
Aquarium lighting, it should be bright, as the plant itself needs it, and the shadow it creates is quite dense, which can badly affect neighboring plants. When content in one with ottely aquarium low-growing plants, it is advisable to arrange side lighting or arrange aquarium near the window. To create artificial lighting apply phytolamps or fluorescent lamps (type LB), whose power is up to 0.5 W / l.
Using incandescent lamps as light sources will not affect growth. ottely. Duration of daylight hours is 12 hours.
The soil that contains part-shaped ottelia, must be silted and contain a large amount of nutrients. When transplanting a plant into a new soil, it is imperative to put clay or a mixture of peat and clay under the roots. Root system ottely well developed, but fragile and brittle roots, in view of which it is better to use large river sand or small pebbles as a substrate.
Soil in aquarium spread with a layer of 5-7 cm. The plant does not need additional fertilizing with minerals.
Breeds part-shaped ottelia in conditions aquarium only seeds. In favorable conditions, the plant constantly blooms. Flowers ottely self-pollinated, and after about two weeks the seed box matures, which then bursts and the seeds sink to the bottom.
In order to prevent the loss of seeds about 10 days after flowering on the box, you must wear a capron cover. In this case, the ripe seeds fall into the cover.
There is also another method of collecting seeds, in which the immature seed box is placed in a separate bowl with a mixture of clay and sand, covered with water and maintained at a temperature of 28-30 ° C. In such conditions, the seeds ripen and fall into the sand. After some time, seedlings will appear from the seeds.
The leaves of these seedlings are different in shape from the leaves of an adult plant: it is lanceolate, elongated. Seedlings need bright light and protection from algae.
After the plants grow to 10 cm, they can be planted in separate containers or aquarium. Particle-shaped otteliya very delicate and fragile plant, and requires careful handling.
