This article provides an introduction to the purple delphinium flower language and symbolism, as well as an introduction to the green plant flowers that represent the meaning of delphinium, let's get to know it together.
Introduction to Delphinium
Delphinium, scientific name: Consolida ajacis (L.) Schur, is a perennial herbaceous plant of the Ranunculaceae family and Delphinium genus. It is named for its unique flower shape, resembling little swallows. The flower diameter is about 4 cm, elegant in shape, and endearing; 35-65 cm tall, stems with sparse branches, leaves palmately divided. The raceme has 3-15 flowers, petaloid, blue or purple-blue, 1.5-1.8 cm long. Delphinium is a plant with a direct root system, few fibrous roots, suitable for direct sowing, and transplanting with soil clumps. It is relatively cold-resistant, sun-loving, heat-intolerant, and dislikes waterlogging, growing best in deep and fertile sandy soil. It is native to southern Europe and cultivated in various provinces of China.
Cultivation Techniques of Delphinium
Propagation Methods
Delphinium can be propagated by seeds or cuttings.
Seed Propagation
The optimal germination temperature is about 15°C, with the best soil temperature below 20°C, and it germinates in about two weeks. Autumn sowing is from late August to early September, first sowing in open ground seedbeds, entering a cold bed or cold room before winter, and transplanting in spring when it warms up. In the south, direct sowing in early spring, thinning to maintain a plant spacing of 25-50 cm. In the north, seedlings are usually raised in advance, transplanted in mid-April, transplanted when there are 2-4 true leaves, and planted when there are 4-7 true leaves. Pay attention to drainage during rainy days. The fruit ripening period is not consistent, and it cracks naturally after ripening, so it should be harvested in time. Generally, ripe seeds are harvested 1-2 times in June, and all are harvested and dried in July. Cutting propagation is carried out in spring, cutting the stems when the new leaves are more than 15 cm long and inserting them into sandy soil.
Division Propagation
It can be done in spring and autumn, generally dividing once every 2-3 years.
Cultivation Methods
In hot summer areas,播种 in late August, and when the seeds germinate and grow 2-4 true leaves in mid-to-late October, transplant them into sunny plots. The seedlings will have 4-7 true leaves in the following March and can bloom from May to July. If grown in a greenhouse in hot areas, the growth period can be shortened, and blooming can be advanced by 2-3 months.
Specifically: Sow in late August, transplant once in mid-to-late September, plant in mid-October, keep the temperature constant, add heat and light from December to the following February, and the blooming period can be advanced to March to May.
Apply nitrogen fertilizer before flowering and more phosphorus and potassium fertilizer after flowering, water appropriately, and increase lighting in October to promote early blooming. When the plant grows to 20 cm high, set up a支架 and stretch a net to prevent lodging.
Precautions
Delphinium requires a sunny and cool growing environment, it can tolerate cold and drought, but not high temperature and moisture, and it is not very picky about soil. However, the following issues should be noted during planting:
① Sowing Time. Spring and autumn can both be sown, but if sowing in autumn, it must be done by mid-September.
② Maintenance. Keep the soil moist after sowing, the simplest method is to cover it with grass and gradually remove the covering after seedlings emerge.
③ Transplanting. When delphinium has 2 true leaves, transplant it into small pots with soil, and change pots again when the seedlings grow larger.
④ Watering. Water when the soil is dry, and water a bit more during the flowering period to avoid excessive dryness.
⑤ Fertilizing. Apply dried manure as a base fertilizer when changing pots, and apply 1-3 times of decomposed cake fertilizer water per month according to the growth condition.
⑥ Controlling Height. After changing pots, use Paclobutrazol to control the height of the plant, specifically: Apply 0.5% Paclobutrazol every two weeks.
⑦ Seed Collection. Collect seeds in time to prevent the fruit from cracking after maturity.
Disease and Pest Control
Common diseases include black spot disease, root collar rot, and chrysanthemum leaf blight nematode disease, which can damage leaves, flower buds, and stems. Use a 30% wettable powder of Thiram at a concentration of 500 times for spray control. Pests include aphids and nocturnal moths, which can be controlled by spraying 10% dimethoate emulsion at a concentration of 2000 times.
White Powder Disease
1. Symptoms: The disease affects the leaves and stems of the plant. Initially, the affected parts of the plant show white powdery mold spots. In severe cases, young leaves and shoots will curl and growth will be inhibited. In the later stage of the disease, black granular structures form in the mold spots, which are the closed ascocarps of the pathogen.
2. Pathogen: The pathogen is the powdery mildew fungus of the Asteraceae family, Polygonum powdery mildew fungus, and Monosporascus fungus, all belonging to the Ascomycetes subphylum, Pyrenomycetes class, and Erysiphales order.
3. Incidence Law: The pathogen overwinters in ascocarps, and in the second spring, it produces conidia and ascospores, which are spread by wind and rain to infect the host. The disease is more severe in wet and cool seasons.
4. Control:
① Reduce the Source of Infection: After flowering, burn the diseased plants and residual bodies together.
② Strengthen Cultivation Management: Pay attention to drainage in the planting area to prevent moisture. Avoid dense planting and maintain good ventilation and light conditions.
③ Drug Control: When the disease occurs, spray with a 50% wettable powder of Benomyl at a concentration of 1000 times, or a 15% wettable powder of Triadimefon at a concentration of 800-1000 times.
Delphinium Root Collar Rot is a devastating disease of delphinium. The pathogen invades the plant from the roots and root collar, cutting off the water supply, causing the plant to suddenly wilt and die.
Black Spot Disease
1. Symptoms: The disease affects the leaves, petioles, stems, and flowers of the plant, mainly the leaves. Lower leaves of the plant usually develop the disease first. The affected leaves show bright black spots on the front and irregular-shaped spots on the back.
2. Pathogen: The pathogen is Pseudomonas syringae pv. delphinii (Smith) Young, Dye et Wilkie.
3. Incidence Law: The pathogen overwinters on the soil surface or diseased leaves, and when conditions are suitable in the second spring, the bacteria are spread by rainwater and enter through the host's stomata, causing infection and damage. The disease is more severe in conditions of heavy rain and moist soil.
4. Control:
① Remove and burn diseased leaves immediately, and cut old stems in autumn.
② Use streptomycin at a concentration of 1000 times for spray control when the disease occurs.
③ Cultivate disease-free seedlings.
