Key points of ramet propagation of red banana

Banana originated in India and is now cultivated throughout the north and south of China. Banana flower language is a solid future, now often used as illustration material, and planted in the courtyard, window or pool are very beautiful.

red banana

Artificial propagation of red banana is mainly carried out by ramets. 5-8 Month for the appropriate period, at this time is the peak of growth, can be dug in the strong mother plant next to the growth of good young plants planted. When the pot must choose shelter, full watering after planting, but not water. Keep the soil moist in summer and spray water regularly on the leaves to increase the air humidity appropriately. After about 20 days of cultivation, the seedlings can grow new leaves.

Basic information of golden canna

Scientific name: Canna generalis cv, Striatus alias: golden leaf green vein canna, mosaic canna, golden vein big flower canna, golden leaf green vein Yan Hua.

Family: Canna family, Canna genus. It is a cultivated variety of large flower canna.

Perennial bulbous flowers, plant height 70 ~ 100 cm. Rhizome recumbent hypertrophy. Stems and leaves are powdery, stems fleshy, unbranched. Leaves alternate, long elliptic lanceolate, leaf surface pale yellow, veins green. If the climate is mild, it can bloom all year round, usually from June to October. Racemes terminal, petals straight, with 4 petalized stamens, orange-red.

Canna golden-veined leaves bright color, large color Yan flowers, long flowering, rough nature, easy to plant walls, and flowers bloom in the heat when few flowers. Can be used as potted garden layout, windowsill and balcony, such as sufficient light.

(1)C. Generalis): also known as Tan Hua, Hong Yan Jiao, Zhuangyuanhong, is a variety of horticultural hybrids. The leaves are broad, long elliptic-lanceolate, 20 - 30 cm long, 10 - 13 cm wide, entire. May ~ November flowering, racemes terminal, with 2 ~ 3 branches, calyx and corolla are not obvious, there are 5 staminodes, 3 ~ 4 of which expand into petal-like, with milky white, orange yellow, yellow, pink, orange, red, purple and other colors, or with various spots or sprinkled gold, sometimes two colors alternate.

(2)Canna purpurea (C. Warscewiezii): Pseudostems purplish red, stout. Leaves ovate or ovate-oblong, 20 - 50 cm long, 15 - 20 cm wide, dark green, purple or bronze. Flowers from May to November, racemes 15 cm long left to right, terminal, with 2 to 3 branches; bracts purple, sky blue powdery, sepals lanceolate, purple I corolla lobes lanceolate, crimson or orange-yellow, slightly blue outside.

(3)C. Indica): also known as small canna, red banana, small banana, is one of the original species of modern canna. The leaves are broad, ovate-lanceolate, like banana leaves. Flowers terminal, racemes, stamens degenerated into petals, red or yellow.

[Gold Veined Canna Breeding] Plant and sow. It is mainly propagated by ramets.

(1)Rite: early spring before germination. Dig out or pour out fresh and strong rhizomes from pots, cut them into small pieces with 2 ~ 3 bud eyes, and plant them separately. Rooted young plants can also be cut from clustered plants during the growing season and planted separately.

(2)Sowing: Sowing can be carried out after the seeds are mature, or dry storage or sand storage can be carried out until April to May of the following year. Because the seeds are hard, they need to be rubbed with a file or a sharp blade before sowing, or soaked in warm water at 30°C for 24 hours, or soaked in dilute sulfuric acid for 30 ~ 40 seconds, then removed, washed, and then sown. After sowing, it needs to be covered with plastic film to keep warm. Under the temperature condition of about 25°C, it can germinate after 20 ~ 30 days. Seedlings can flower in the same year, but the resulting offspring will produce atavism and lose the beautiful markings on the leaves.

[Key points for cultivation of golden canna]

(1)Temperature: warm, the most suitable temperature for growth is 18 ~ 30°C. Not cold tolerance, when the temperature is lower than 16°C when the plant grows slowly, gas; temperature dropped to 7°C below the frost will wither. If the temperature above 16°C can be maintained in winter, it can grow and bloom all year round. The overwintering temperature of rhizomes should not be lower than 5°C, and underground stems will be frozen below 0°C. In the Yangtze River valley, rhizomes can safely overwinter in soil, but some dwarf varieties and potted varieties are vulnerable to freezing damage, so warm measures should be taken to prevent freezing. Potted plants can overwinter in indoor environment where stems and leaves are cut off before winter and the temperature is above 5°C. When the summer temperature reaches 32°C or above, it is necessary to strengthen ventilation, appropriate shading and environmental spraying to reduce the temperature.

(2)Light f likes sufficient sunshine, can bear half shade, potted plant needs appropriate shade when summer high temperature, sunshine is too strong will make leaf yellow and coke sharp, coke edge. Also avoid too much shade, otherwise the branches and leaves are thin and weak, the amount of flowering is reduced or even no flowers, and the beautiful stripes on the leaves fade, reducing the ornamental value. When flowering plants will be placed in a cool place, can extend the flowering time.

(3)Moisture: like wet soil environment, during the growth period should be fully supplied with water, keep the basin soil moist. When the pot soil is too dry, the leaves are curly and yellow, and affect tillering and shorten flowering. Also avoid basin soil wet waterlogging, basin soil too wet easily lead to plant rotten roots.

(4)Environmental humidity: like humid environment. According to measurements, when the relative humidity of the air is greater than 98%, each flower can bloom for 2 days; when it is lower than 70%, the life of the flower is only half a day. During the growth period, especially during flowering, water should be sprayed regularly to the branches and leaves and the surrounding areas to increase the relative humidity of the air. Too dry air can also cause curling and burning of leaves.

(5)Fertilization: Happy fertilizer. In addition to applying sufficient base fertilizer when putting on pots, nitrogen, phosphorus and potassium fertilizers should be applied once a month during growth and flowering to promote tall and robust stems and leaves, vigorous tillers, green and plump leaves and bright colors. Avoid nitrogen fertilizer alone, otherwise the leaves spend less, leaves on the beautiful stripes fade green. When the fertilizer is insufficient, the plant grows weak, the leaf color is dim, and the flower cannot be bloomed or the flower is rare. Fertilization should be stopped during flowering period, and fertilizer should be supplemented in time only after flowering combined with pruning.

(6)Pruning: The flowering period of each inflorescence of Canna is 10 ~ 15 days. After flowering, the residual flowers should be cut off in time to reduce nutrient consumption. At ordinary times, cut off the yellow leaves that appear at any time to promote tillering and continuous flowering. To control plant height, irrigate 15% paclobutrazol 1 000 ~ 1 500 times after germination, once every 20 ~ 30 days, 3 ~ 4 times in total.

(7)Upper basin and turning basin: upper basin should be carried out in early March. Potted plants should choose dwarf varieties. Planting should choose a large pot with a diameter of 30 ~ 40 cm, and families can choose a medium pot with a diameter of 20 cm. Each pot should be planted with 2 ~ 3 strong buds, and the soil depth is 5 cm. Loves loose fertile and well-drained soil, matrix can be made of decayed leaf soil, garden soil and chaff ash, and mixed with a small amount of cake fertilizer or bone meal as base fertilizer. Turn pot 1 time every spring, replace new soil when turning pot, cut off old stem, divide new stem, replant, generally a pot plant can be divided into 3 pots.

(8)Pest control: virus disease, anthracnose, rust, blight and aphids, banana bracts and other pests harm.

[Common problems of golden canna cultivation]

common problems Cause Leaves curl up, yellow and produce burnt edges ① Too much light;② Too much soil in the basin; ④ Too dry air;④ Poor growth potential caused by virus disease and dim leaf color. No flowers or few flowers Often due to lack of fertilizer potted plants grow too tall ① No dwarf varieties selected;② Insufficient light; ④ Excessive nitrogen application;④ No dwarfing hormone irrigation
