Bird of Paradise (strelitzia reginae) is a perennial herb, caulless. Leaf blade is oblong-lanceolate, 25-45 cm long, ca. 10 cm wide, apically acute, base rounded or cuneate, lower margin undulate; The petiole slender.
Flowers are several on a total pedicel about as long as petiole or slightly shorter, bearing a Buddha spathe below; Bracts are naviculate, 20 cm long, green with purplish red edges, sepals lanceolate, 7.5 -- 10 cm long, orange, arrowheads with aurate lobes at base, subequal to sepals, dark blue; Stamens are equal in length to petals; Anthers are narrowly linear, styles prominent, stigma 3.
Bird of Paradise (strelitzia reginae) should have no less than 4 hours of direct sunlight a day, preferably all day long. Take protective measures when the sun is strong. In the main flowering period in winter, sufficient sunshine is beneficial to increase the yield of flowers. Lighting regulation emphasizes the management principle of "not shade in winter, not sun in summer". The leaves of the plant look better in shade, but there are fewer flowers.
The temperature management of Bird of Paradise is of great significance for Flower production. In general, Bird of paradise is stunted in growth above 40℃, suffers from freezing damage below 0℃, and grows well in the range of 18℃-30℃. It is best to ensure the temperature at night (13℃-18℃) and the temperature during the day (31℃-35℃). In the appropriate temperature range, flower buds can be formed in the axils of each leaf of Bird of Paradise.
Ensure an adequate and regular water supply. Keep the soil moist all the time except between September and February, when the plant needs to be dry. The use of well-drained media is the key to cultivation management. Bird of Paradise is afraid of waterlogging, because its fleshy roots are drought-tolerant but water-resistant.
Bird of Paradise (strelitzia reginae) should strengthen ventilation before going out of the nursery, so that the plant undergoes exercise, so as not to produce potted flowers after sales due to environmental inadaptation and affect the growth and flowering, and pick yellow leaves, sick leaves. The harvest of cut flowers is generally cut when the first floret is in bud or fully open, and the cut flowers for storage and transportation can be cut before the bud shows color. The pedicels of cut flowers should be more than 70 cm. After being treated with water, it can be stored at 7-8℃ for one month after harvest. If long-distance transportation is needed, cut flowers should be transported at a dry temperature of 7-8℃ in the moisturizing box after soaking in water. Lower than 7℃ is easy to cause low temperature injury. During storage, cut flowers are sensitive to gray mold, so they need to be protected with fungicide before storage and transportation.
Bird of Paradise (strelitzia reginae) is evergreen, plant chic, with a clear, elegant sense. The Flowering period of Bird of Paradise can reach about 100 days, each flower can open for 13-15 days, 1 flower, another flower in succession and open. Cut the vase can be up to 15-20 days, flower arrangement multi-purpose natural flower arrangement, the 2 Bird of Paradise high and low match, in the other flowers with leaves, close to each other, like a pair of lovers in love in each other's heart, is the best for indoor viewing.In southern regions of China such as Fujian, Guangdong, Hainan, Guangxi, Hong Kong and Macao. Bird of Paradise can be planted in the courtyard corner, used for courtyard landscape and flower beds, flower border ornament.
Harmful symptoms: Harmful leaves and stalks, disease spots round, the edge of the reddish-brown line, the central brown flat. When the conditions are right, conidia by sputtering water spread, from the wound invasion, humidity is easy to come on.
Prevention and control methods: Found the disease along the edge of the leaf cut out, Bird of Paradise can also be removed and burned or buried deep. Spray 25% Charcoal Trane Wettability Powder 500 times Liquid or 40% Polysulfide Gel Suspend.
Prevention and control methods: Found root rot should be timely soil disinfection and control watering, remove rotten roots, and in the soil with quicklime or 70% pentachloronitrobenzene disinfection of the soil. At the beginning of the disease, Bird of Paradise or roots were alternately sprayed with 50% rikujing wettable powder 800 times, 50% benzodiazepine wettable powder 1000 times and 70% methyl tobujin wettable powder 500 times, spraying once 10 days.
Prevention and control methods: Remove the disease and residual body, centrally burned; At the early stage of onset, the patients were sprayed with 72% streptomycin soluble powder 4000 times or neophytomycin 4000 times, once every 10 days, for 2-3 times.
Prevention and control methods: Timely removal of diseased strains found, centrally burned; Cut off the disaffected Bird of Paradise leaves and smear the wound or incision with 30% alkaline copper sulfate suspension agent. At the beginning of the disease, 30% basic copper sulfate suspension agent 400 times liquid or 70% substituted zinc wettable powder 500 times liquid were sprayed on the foliar surface once every 10 days for 2-3 times continuously.
Prevention and control methods: During the onset of the disease, use 80% diacendan wettable powder 500 times liquid or 75% chlorothalonil 500 times liquid, torbujin 500-800 times liquid, 50% carbendazim 1000 times liquid, 50% pulhin wettable powder 1500 times liquid, 60% Antimicrol wettable powder 500 times liquid spray prevention and control.
Control methods: The greenhouse whitefly has a strong tendency to yellow, the sticky oil on the yellow plate was used to trap and kill, or the 40% oxidized dimethoate emulsion was sprayed with 1000 times liquid. Because the insect body is on the back of the leaf, pay attention to fully spray the back of the leaf when spraying.
Harmful symptoms: Also known as cotton red spider. The injured leaves are yellow and white spots at the beginning. When the leaves are serious, they curl, wither and fall off, affecting the growth or not flowering. The adult mites are 0.5-0.6 mm long. The male mite is slightly diamond-shaped, yellowish and slightly smaller. Bird of Paradise likes to live in groups on the back of the leaf feeding, high temperature and drought season prone to outbreak of this disease.
Prevention and control method: Use 20% dichloroacetyl emulsion 800 times solution, or 73% carmite 2000 times solution.
Symptoms of harm: The shell of a female adult is pear-shaped or nearly round, snowy white. The female's shell is silvery white and long. Nymphs hatching yellow-green, ovate, secretion of white wax filaments. Adult, nymphs fixed in the stalks, leaves on the thorn suction leaf fluid, resulting in leaf green, yellow spots. Bird of Paradise branches and leaves turn black, causing early shedding and even death.
Control method: Cut off and burn the insect leaves, or scrape off the insect bodies on the leaves with a knife. Newly hatched larvae were treated with 40% dimethoate emulsion 1000 times solution. In summer at a high temperature, for the medium activity period, we can use 10% imidacloprid powder 2000 times liquid control.
