Planting and propagation methods and cultivation management of aquatic canna

Plant name: aquatic canna, scientific name: Canna glauca, alias: Florida canna.

Aquatic canna is a large perennial herb. Strong nature, strong adaptability, like light, afraid of strong wind, suitable for growing in wet and shallow water, fertile soil or sandy soil can grow well. The suitable temperature for growth is 15-28 ℃, and less than 10 ℃ is not conducive to growth. There is no dormancy period in the place of origin, annual growth and flowering, and winter dormancy in the cold regions of the north. The rhizome needs to be protected through the winter in a greenhouse.

Sexual reproduction and asexual reproduction are available. The sowing time is carried out indoors from March to April. Before sowing, the seed coat should be broken with a steel file, soaked in warm water for one day, and then the seeds should be removed to control dry water before sowing. Asexual reproduction is planted by dividing tubers. From March to April, the tubers were taken out from the soil, and the sundries were removed and segmented with a spade or sharp knife. Each tuber had 2 or 3 strong buds as propagation material.

When potted, the divided tubers can be directly planted in a pot with fertile soil in spring, the growing point is slightly exposed, and then irrigated with water, put in the shady place of the flowers for 5-7 days, and then moved to the leeward and sunny place to cultivate. Open-field planting can choose pool-side wetlands or shallow water to dig holes to plant, the tubers buried in the soil, covered with soil 7cm, after planting to maintain humidity or shallow water. Potted aquatic canna should be placed in a warm, humid and sunny environment to remove weeds in the basin and the old and dead leaves at the base in time, so as to keep the overall plant shape beautiful. Planting in the open field in the south can survive the winter outdoors. In warm areas, tubers need to be dug up and replanted in situ after 2 or 3 years. After entering the vigorous growth period, the plant density becomes larger, which is easy to cause overgrowth, resulting in the decline of the quantity and quality of flowers. The stems that have already flowered must be thinned at the right time, and the stems that are too dense and high should be properly removed to increase permeability and promote the growth of new buds.

Pictures and introduction of aquatic canna

Aquatic canna, the name can tell that the flower must be very beautiful, but in fact it is very beautiful. When all flowers bloom in spring, aquatic canna also joins in, giving rise to yellow flowers as bright as the sun. The origin of aquatic canna is South America, also known as Florida canna. It is an ornamental flower, which is often used in the periphery of road belts, parks and wetlands, as well as greening in factory areas. It has strong anti-pollution ability and purification ability, and plays a very important role in landscaping. The following editor would like to introduce the aquatic canna with its beautiful pictures for appreciation.

Morphological characteristics

Aquatic canna is a large perennial herb with a height of 1 to 2 m; leaves long lanceolate, blue-green; racemes terminal, many-flowered; stamens petalized; flowers with large diameter, yellow, red or pink about 10 cm;; flowering in temperate regions from April to October, year-round flowering in tropical and subtropical regions The aboveground part dies in winter in the temperate zone, the rhizome enters the dormant period, and the tropical and subtropical regions are evergreen all the year round. The biggest difference in morphology and biological characteristics between aquatic canna and other species of Canna is that the rhizome is small, the internodes are lengthened, resistant to flooding, and can grow normally in 20 cm deep water.

Ecological habit

Strong nature, strong adaptability, like light, afraid of strong wind, suitable for growing in wet and shallow water, fertile soil or sandy soil can grow well. The suitable temperature for growth is 15-28 ℃, and less than 10 ℃ is not conducive to growth. There is no dormancy period in the origin, annual growth and flowering, winter dormancy in the cold areas of the north. The rhizome needs to be protected through the winter in a greenhouse.

Cultivation

Aquatic canna is highly resistant and has no significant disease and insect damage. However, attention should be paid to keep the water clean, salvage duckweed in time and remove weeds. Attention should also be paid to the harm of snails in the southern region.

The control method is to mix trichlorfon and sawdust into a cloth bag, and then tie the cloth bag to the pseudo-stem to make the bag float on the water surface and fluctuate with the water. After the liquid spread, snail damage can be prevented.

When potted, the divided tubers can be directly planted in a pot with fertile soil in spring, the growing point is slightly exposed, and then irrigated with water, put in the shady place of the flowers for 5-7 days, and then moved to the leeward and sunny place to cultivate.

It is also a good flower plant for viewing flowers and leaves in the courtyard, and can be used as cut flowers. It is also a good material for air purification, and has a certain resistance and absorption capacity to harmful gases such as sulfur, chlorine, fluorine, mercury and so on.

Garden function

It can absorb several harmful gases in automobile exhaust and greenhouse gases such as carbon dioxide.

After enjoying so many pictures of aquatic canna and the editor's introduction to it, we should have a more comprehensive understanding of aquatic canna. Aquatic canna has strong resistance to diseases and insect pests, but it still needs to keep the water clean and remove weeds in time. Snail damage should be paid attention to when planting in the south. Aquatic canna has been introduced and planted all over the world, and it has high economic value. Friends who like it can learn more about it.
