The Propagation method of Fulukao

Flukao is a perennial perennial herbaceous flower, which is not difficult to plant artificially and can endure low temperature. It can survive the winter in the open field in the northeast of China, so it is very suitable for planting in loose sandy soil. As there are many varieties of horticulture, and the flowering period is very long, it is very popular. The editor will briefly introduce the breeding methods of Fulukao for you.

Fulu textual Research

The common propagation methods of Fulukao are split-plant propagation, cutting propagation and sowing propagation. Ramet propagation is easy to operate and survive quickly, which is carried out in early spring or autumn. The sprouting plants around the mother plant are dug out and planted with complete roots as far as possible to improve the survival rate. Cutting propagation is carried out after flowering, which is suitable for mass production. Take the fully growing and robust branches, cut the cuttings 3 cm long, each cuttings can retain 2 leaves, soak the cuttings base in ABT1 200mg / L rooting powder solution for 30 minutes, then insert the cuttings into clean sterile soil (the soil can be sterilized by watering the seedling bed with potassium permanganate solution), the depth of soil insertion is 1 cm 2 cm, the spacing is 2 cm, and the soil moisture can be maintained. It can take root in about 20 days. If the weather is hot, 50% carbendazim 800 × 1000 times solution can be sprayed once or twice to prevent cuttings from rotting. The main method of sowing and propagation was autumn sowing, and it was sowed in the open field seedling bed at the beginning of September. The suitable temperature for germination was 15: 20 ℃, and the seedlings emerged in about 7 days. The seedlings were transplanted when there were 2-3 true leaves, and moved to the cold bed for winter in the first ten days of October. When the height of the seedling is more than 10 cm, the top tip is removed to promote its branching and shaping.

The Propagation method of Fulukao

Split-plant propagation of Fulukao

The ramet of Fulukao is very simple and suitable for family reproduction, which is usually carried out in early spring or autumn.

The ability of some buds of Phlox root is very strong, and lateral buds often burst out in the process of growth. The sprouting plants around the mother plant are dug out and planted to ensure the complete root system as far as possible, so as to improve the survival rate.

Fulu Kao sowing and breeding

Fulukao is often sown and propagated, sowing in autumn in warm places and spring in cold places, and the suitable temperature for germination is 15-20 ℃.

The vitality of seeds can be maintained for 1-2 years. Sowing in autumn, seedlings after a transplant, overwintering in a relatively low temperature environment, early spring do not come out too early, appropriate fertilizer supplement, April will be normal growth!

Propagation of Propagation by Cuttage

Root insertion: in spring and autumn, combined with ramet planting, part of the root is cut into small segments about 30 cm long and buried in plain sand. Under the condition of 15 to 20 degrees, keep the soil moist, and new buds can grow in about 30 days.

Stem insertion: in spring, summer and autumn, usually after flowering. Stem cuttings are suitable for mass production, combined with pruning, taking fully grown branches, cutting cuttings 3 to 5 centimeters long, and inserting them into clean aseptic sand. The row spacing is 2 to 3 centimeters, and the soil moisture can be maintained. It can take root in about 30 days. Pay attention to spray carbendazim solution 1 to 2 times 1000 times in summer to prevent cuttings from rotting.

Leaf insertion: in summer, take leaves with axillary buds (leaves retain about 1 stop 2), with 2 cm long stems, insert them in clean aseptic sand, pay attention to shade, and keep the soil moist, rooting for about 30 days. The operation is complicated and the survival rate is low.

Fuluke pressing strip propagation

The annual or biennial branches close to the ground are bent and buried in the soil, and the upper end of the branch is exposed to the ground. When pressing, the bark of part of the branches buried in the soil is cut in advance (which can release nutrients and is conducive to rooting). It can be separated and planted from the mother plant after taking root for about 30 days.

The breeding method of Fulukao

Fu Lukao, alias: oleander, plum blossom, Platycodon grandiflorum Caryophyllaceae: Huacheng (plus grass word prefix) family, Fu Lukao is native to southern North America and is now widely cultivated all over the world. The name of the genus Phlox means Flame, and the original flowers are red because of Phlox. The name of the species is in memory of Drummond.

Herbs annual, 15-45 cm tall. Stem erect and much branched, with glandular hairs. Basal leaves opposite, upper leaves sometimes alternate, leaves broadly ovate, oblong to lanceolate, 2.5-4 cm long, apex pointed, base attenuate, slightly clasping. Cymes terminal, Corolla salverform, 2-2.5 cm in diameter, lobes 5, spreading, round, flower tube slender, soft hairs, original red. There are light red, purple, white and other colors in horticulture. The florescence is from May to June. Capsule elliptic or suborbicular, 3-lobed at maturity, seeds Obovate or elliptic, abaxially raised, ventral flattened.

Varieties are: round petal species, petal lobes large and wide, the shape is round. The petal species var.stellaris has three teeth at the edge of the petals and longer middle teeth. Var.firbriata, Corolla lobes denticulate at the margin. Radiation species var.radiata, Corolla lobes lanceolate-oblong, apex pointed. Sex likes to be warm, slightly resistant to cold, and avoid extreme heat. Cold beds can survive the winter in North China. Should be well drained, loose loam, not resistant to drought, avoid waterlogging. Commonly used sowing and breeding, warm autumn sowing, cold spring sowing, the suitable temperature for germination is 15-20 ℃. The vitality of seeds can be maintained for 1-2 years. Sowing in autumn, after one transplant, the seedlings can be transplanted to the cold bed in the first and middle of October, and then transferred to the ground bed in early spring, fertilized in time, and planted in the middle of April. The florescence is longer. The mature period of the capsule is different. in order to prevent the seeds from falling, the inflorescence can be cut off and dried and threshed when most of the capsules are yellowing. Fu Lukao plant is short and rich in color, which can be used as plant material for flower beds, flower borders and rock gardens, as well as potted plants for interior decoration. Varieties with taller plants can be used as cut flowers.
