The main producing areas and planting methods of Fulukao

[alias] oleander, plum blossom, Platycodon grandiflorum.

[varieties, forms and varieties] according to flower color: (1) monochromatic: there are white, goose yellow, a variety of different shades of reddish purple, as well as lilac and dark purple. (2) complex color: including internal and external color, crown tube and crown edge, throat spots, crown edge stripes, white pentagonal star spots in the middle of crown edge, etc. (3) tricolor: such as rose red with yellow heart in base white, or purplish red with white star blue dot and so on.

In addition, there are dwarf species (var.,uura) and large flowers (var.gigantea).

[Origin and distribution] originating from southern North America, it is widely cultivated in many countries.

[habit]

The cold resistance is not very strong, the sex likes the mild climate, does not like the extreme heat, basically can overwinter in the open field in Shanghai area. Like good drainage and easy soil, not resistant to drought.

[propagation] it was sowed in the open field seedling bed or pot at the beginning of September in autumn, and the optimum temperature for germination was 15 ~ 200C. Sprouting neatly. When the temperature is high, it lurks without sprouting.

[cultivation] the seedlings grow slowly, although they can survive the winter in the open field, but the seedlings are too small to manage, so they are accustomed to overwintering in a cold bed (4 to 5 inch pots) and planting in late March, with a distance of 30 cm and a dwarf species of 20 cm. If sowed in the greenhouse in early spring, it can also blossom from September to October, but it does not grow well because of the heat, the clump is small and the development is poor, and the ornamental value is not high.

[seed harvesting] the capsule is uneven in maturity and can crack and scatter the seeds at maturity. It takes too much work to harvest one by one; when most of the capsules in the whole inflorescence turn yellow, they can be picked at the total pedicel and dried and threshed.

[use] for flower beds and flower border materials, can also be used as indoor potted flowers in spring.

It can be planted in a large area on flat land, sloping land or hanging on the wall, or planted in a flower box in front of the window. Because of its long flowering period and long green period (330mur36 days), Cong Fulukao is favored by the masses, especially when it blossoms in early spring. It is most suitable for planting flower beds in the courtyard or in the rock garden, and the group ornamental effect is excellent. It can be decorated with decorative materials or planted in hanging pots. Used for flower beds, flower borders, quilts.

Symptoms: Phlox leaf blight the main feature of the disease is that the lower leaves of the plant first withered and yellow, and gradually developed upward, until the whole branch died. The disease occurs seriously in old plants, but does not affect seedlings and cuttings with new roots.

Pathogen and pathogenesis: the pathogen of Phlox leaf blight is an abiotic factor, that is, the disease is a non-infectious physiological disease. The reason is that the new branches germinated from the old stems in spring do not get enough water supply, so that the lower leaves wither and die at first.

Prevention and treatment methods: in view of the cause, when the old stem germinates new branches in spring, increase sprinkler irrigation, increase soil water content and air humidity, in order to reduce plant transpiration and alleviate the disease, but generally can not return to normal.

The above is the introduction of the shape and growth habits of the clump Fulukao, as well as the treatment of its symptoms. I hope it can be helpful to the majority of flower friends. Please continue to pay attention to the succulent flower bed and learn more about flower care.

Fu Lukao prefers sandy loam and humid environment with good drainage. Cold resistance, avoid cool sun, avoid waterlogging and saline-alkali. The strongest growth in sparse shade, especially shade or western background, or mixed planting with flowers slightly taller than it, such as echinacea, is more beneficial to its flowering and root Fulukao cultivation techniques 1. Open field cultivation should choose the land with leeward and sunny and good drainage, combined with soil preparation and application of stable manure or compost as base fertilizer, the effect of diammonium phosphate is the best. From the beginning of May to the middle of May, the suitable distance from plant to 40~45cm is suitable, and the planting depth is slightly deeper than the original depth 1~2cm. Often water the soil during the growing period to keep the soil moist. During the peak growing season from June to July, human dung or cake fertilizer can be recovered for 1 or 3 times. In the northeast, some varieties should be covered with grass or soil to survive the winter. In the middle of November, frozen water should be watered once, and "green water" should be watered again at the beginning of spring. (2) the pot should be changed once after the new buds germinated every spring, and the soil should be changed when changing the pot. 3 parts of garden soil, 3 parts of deer dung and 1 part of furnace ash should be mixed. A small amount of diammonium phosphate can be applied to the bottom of the basin as base fertilizer, and the basin should be watered thoroughly after changing the basin. When the new buds grow to 6~7cm, some robust buds should be selected according to the size of the basin, and the extra buds should be cut out. Generally speaking, the pots with a diameter of 20cm can leave 4-5 buds. Manure should be applied in time during the growth period, and mature human feces and urine, bean cake water and chemical fertilizer solution can be used for topdressing every 2 to 3 weeks. Pay attention to watering, keep the soil loose and moist, and pay attention to adjust the phototropism to make the plant strong and straight. There are few diseases and insect pests in Fulukao, and there are occasional leaf spot disease and aphids. When leaf spot occurs, 50% carbendazim 1000 times solution can be sprayed for prevention and control. Aphids can be brushed off with a brush dipped in dilute laundry powder, and 1500 times of omethoate EC can be sprayed when a large amount occurs. The propagation method of Furukao can be propagated by sowing, ramet and cuttage. 1. Sowing and reproduction: sowing cold beds in northern areas to survive the winter, we should pay attention to anti-freezing, spring sowing should be earlier, flowering is shorter than autumn sowing, and more dead in the rainy season. Split propagation: break off the sprouting tillers of the mother plant by hand before May, plant every 3 to 5 buds together, pay attention to watering, open field planting can be divided into plants every 3 to 5 years. 3. Cutting propagation: when the new buds grow to 5CM or so in spring, break the buds off, insert them into the seedbed and shallow basin filled with plain sand, buckle with plastic film, and place them in a place where the indoor sunlight is not direct. If the reproduction quantity is not too large, you can set up a shade net shed to cut, the temperature is about 20 degrees Celsius, spray on the leaf surface and seedling bed (1000 times omethoate + 1000 times carbendazim solution), have insecticidal and germicidal effect, and can take root in one month. The variety classification of Sugen Fu Lukao 1. Dwarf plant height 30~50cm, leaves oval-lanceolate, leaves and stems purplish, smooth leaves, whole plant glabrous, large flowers, cold tolerance.
