When the buds are in bud, Common poppy(Papaver rhoeas) droops like a girl in ancient times with her head lowered to meditate. When the flowers bloom, they descend like a fairy. Flowering period is in summer, color red, white, purple, blue and other colors. It is a fine grass flower for beautifying flower beds, flower borders and courtyards in spring. It can also be potted or cut.
Common poppy is an annual herb with entire outstretched bristles, thinly glabrous. Stems are erect, 25-90 cm tall, branched, covered with yellowish bristles.
Common poppy leaves ARE alternate, leaf blade lanceolate or ovate, 3 -- 15 cm long, 1-6 cm wide, pinnate, lower total cleavage, lobes lanceolate and two back to pinnate shallow crack, the upper part of deep crack or shallow crack, lobes lanceolate, the upper course dentate pinnate shallow crack, lobes usually large, small lobes apex acuminate, both sides are flaxen hair, bulging veins in the back, on the surface slightly concave; Lower leaves are sessile, upper leaves sessile.
Common poppy flowers are solitary at the apex of stems and branches; Pedicels are 10-15 cm long, covered with yellowish spreading bristles. Buds are oblong-obovate, pendulous; common poppy has 2 sepals, broadly elliptic, 1-1.8 cm long, green, outside bristle; Common poppy has 4 petals, rounded, transversely broadly elliptic or broadly obovate, 2.5 -- 4.5 cm long, entire, sparsely crenate-dentate or apically notched, purplish red, base often spotted with deep purple; Stamens are numerous, filaments filiform, ca. 8 mm long, deep purplish red, anthers oblong, ca. 1 mm long, yellow; Ovary is obovate, 7-10 mm long, glabrous, stigma 5-18, radiate, with a flat, margin crenate discoid.
Common poppy capsule is broadly obovate, 1-2.2 cm long, glabrous, with inconspicuous ribs.Seeds numerous, reneform oblong, ca. 1 mm long.
Common Poppy flowering period is from Mar. to August.
Common Poppy is native to Europe and cultivated as an ornamental plant all over the world and in China.
Common poppy is suitable for growth and development at a temperature ranging from 5°C to 25°C. In areas with high spring and summer temperatures, the flowering period is shortened and the temperature difference between day and night is large. Low temperature at night is conducive to growth and flowering, and it grows well in high altitude mountain areas, and its color is more gorgeous.Life span is 3-5 years.
Common Poppy is hardy and shy of summer heat. It likes sunny environments and well-drained, fertile sandy loam soil. Common poppy can not tolerate transplanting, avoid continuous cropping and water.Since the broadcast.
Common Poppy likes sunny and airy places, cold resistant, moisture resistant, heat, not suitable for planting on the soil of too much fertilizer, not suitable for repeated planting. Common poppy should not be in the low-lying, wet, water and fertilizer, poor light of the place seedlings and planting; The soil requirement is not strict, but with loose fertile sandy loam is best, row spacing is 20 cm, after sowing, cover with mulching film, or sowing in early spring when the surface just thawed, after emergence of seedlings gradually uncover mulching film.
In January, Common Poppy put mostly loose old pot soil in a 20cm inner diameter pot, press it flat, sow 20 to 30 seeds, cover the soil so that no seeds can be seen, and soak the pot with main water after sowing. Seedling unearthed, a few times thinning, to the weak, stay strong, finally stay 3 to 5 plants colonization. When the height of the plant is 30 cm, gradually fill in the planting soil to the edge of the mouth to prevent the plant stems from falling thin. Keep adequate light, clean air, not less than 5℃ at night, avoid drought and waterlogging, and can bloom in March, until the "May Day" section.
Common poppy is usually cultivated as a biennial. When the seedlings have 5-6 leaves, thinning is carried out, and the row spacing of the plants is generally 30×30 cm. Common Poppy isn't portable, so it's best to live in a garden.
Common Poppy Apply thin liquid fertilizer 2-3 times before flowering, but not too much fertilizer, otherwise it is prone to pests and diseases. The ground is planted in overwintering before applying twice thin fertilizer, to bloom before applying a liquid fertilizer. Apply a final topdressing before flowering to make the flowers big and colorful and open strongly.
Do not overwater the plants while they are growing, but keep them moist. In general, it is not necessary to water frequently for ground planting. For pot planting, water should be watered once every 3 to 5 days depending on the weather and the situation of pot soil. It is better for the development of Common Poppy to use 60% of the maximum field soil water capacity. Overwintering when less pouring, spring growth should be more pouring.
After transplant, the temperature of Common Poppy is maintained at about 20℃, and the buds can appear in 7-10 days. If the infected plant is found, it should be treated in time and field hygiene should be paid attention to. Do not make the garden hot and humid or poor ventilation. Avoid continuous cropping.If you cut off the dead stalks that have bloomed, you can prolong the flowering period and make the flowers large and beautiful. Seeds mature uniformly, so they can be harvested at once.
It is usually grown for 2 years. Common Poppy flowers and plants of the same genus are taproot tropical, have few fibrous roots, and are not resistant to transplantation, so direct propagation should be applied. If it is needed for garden layout, it is better to grow seedlings in a nutrition bowl or small paper basin, and transplant them in a bowl or basin, otherwise it is difficult to survive or grow poorly. According to the climatic characteristics of the decision of sowing time, the northeast region is cold, and can be in spring as early as the initiation. Seed are small, sowing to fine, the use of drill, row spacing 25-30 cm, in the severe winter in the surface of hay cover cold. The optimum temperature for seed germination is 20℃. Home can live in the pot.
Spring and autumn can be sown, under normal circumstances, spring sowing in March to April, flowering in June to July; Autumn seeding is from September to November, and flowering is from May to June of the following year. In order to collect seeds, it is best to sow in the autumn. Soil arrangement should be fine, do bed pouring permeable, and then broadcast or drill. Because Common Poppy's seeds are small, the soil needs to be leveled and beaten, and a thin layer of sand can be applied instead of being covered after sowing. Soil thickness is no longer visible, seeds should be appropriate (0.2-0.3 cm). In North China, it is difficult for seedlings to survive the winter due to the severe cold in winter, so direct seeding in the "Minor Snow" in early winter is usually adopted, so that seedlings can germinate and grow as early as possible in spring.
Common Poppy diseases include seedling blight, which is sprayed with 25% tobutzine WP 1000 times liquid. Usually after the emergence of cotyledon with 1000 times of liquid chlorothalonil or a spray every week, 2-3 times in a row. The insect pest has the aphid harm commonly, the adult insect nymph is dense in the tender shoot, sucks the SAP on the leaf. 35% ovium net emulsion of 1000-1500 times, 2.5% Uranus emulsion of 3000 times, 50% methaphidum emulsion of 1000-1500 times, 10% permethrin emulsion of 3000 times, 2.5% kungfu emulsion of 3000 times, 40% chlorpyrifos emulsion of 1500 times, 40% oxidized dimethoate of 1000 times, and 2.5% spritz extract of 1500 times.
Common Poppy is not only beautiful in flowers, but also has high medicinal value. Take medicine to call yung poppy, poisonous, have cough, analgesic, stop diarrhea, hypnosis, wait for action, its seed can fight cancer to change tumor, prolonging life.
Common Poppy's colorful and beautiful flowers can be used in Flower beds, flower borders, POTS or cut flowers. Used as a cut flower, Common poppy must be cut in the elliptical half, immediately immersed in warm water, to prevent excessive milk outflow, or flower branches quickly shrinkable, flowers can not fully open. It is planted in the park, and the scenery is very pleasant. Because there are many flower buds on a plant, Common poppy can keep a long ornamental period. If sown by stages, it can be opened from spring to autumn.
