The color of the leaf plate is the hallmark of this plant: aponogeton curly red; aponogeton curly green; aponogone violet; aponogeton dark green; Apono-blue; aponogeton Luzenz (bright green color); apono-green green with double corrugation (it has a wide wave and a small corrugation, its lateral line is wavy). Due to its high decorative qualities Curly hawk very popular with aquarists.
For Curly hawser will fit aquarium any volume. Planted as a rule, on the average plan.
AT aquarium grows throughout the year, slowing growth only in the fall and spring. For content of aphogenetic curly tropical needed aquarium, whose water temperature should be around 24-25 ° C. With slower growth, the temperature can be reduced to 18-20 ° C.
If there are heat-loving plants in the aquarium, then they do not reduce the temperature. For aponogetona soft water is needed, the hardness of which should not exceed 6-8 ° and the neutral reaction of water in the range (pH 6.5-7.2).
Periodically, it is necessary to change 1 / 5-1 / 4 of the volume of water, since aponogatone grows poorly in stagnant water. Aquarists advise to plant this plant in spacious aquariums because of its rapid growth. Although the tuber is not characterized by a dormant period, occasionally they need to be removed from aquarium and dry to avoid exhaustion.
TO lighting the plant has low consumption, withstands slight shading, can grow in the shade of other plants. But with a strong lack of light, the aponogeton is drawn out and its design, the color of the leaves deteriorates.
Lighting can be natural and artificial. Lighting is selected individually, taking into account the existing conditions – the location of the aquarium in the room, the frequency of planting, etc. Artificial lighting can be side and top, for its creation they use incandescent and fluorescent lamps.
Duration of daylight hours ranges from 10 to 14 hours. Moderate silted soil is necessary for aponogeton. When changing water, it is necessary to siphon the soil using a funnel, as this plant does not like excess organic matter.
It is better to use small pebbles as a soil, which will greatly facilitate cleaning, it is better for gas exchange, and, consequently, the aponogeton root system develops better. The soil layer usually does not exceed 5 cm. On condition Curly hawser positive effect mineral supplements.
Complex fertilizers are applied when changing water at the rate of 1-2.5 g per 100 liters of aquarium volume. The dose is calculated based on planting density.
Breeding Curly hawser possibly vegetatively and seeds. The plant blooms at the end of summer, forming seeds.
Seeds are sown in water-covered sand. For seed germination, a temperature of 26-28 ° C is necessary.
Seedlings should be protected from fouling. Young plants with 4-5 sheets are transplanted into aquarium with a low water level. In the vegetative reproduction method, the tuberous rhizome is cut into 3-4 parts, avoiding damage to the growth buds.
The vegetative breeding method is applicable only at the end of the spring dormancy period.
