Introduction and culture methods of torch flower how to grow torch flower like torch flower

Torch flower is a beautiful ornamental flower, torch flower often appears in some poems, metaphor grand and warm scene, torch flower can be planted in the lawn or planted next to rockery, used as a backdrop. Let's take a look at the knowledge of Torch Flower.

I. introduction of torch flowers

Torch flower, also known as red fire stick, is native to southern Africa. It is more hardy and can survive the winter in the open field in the middle and lower reaches of the Yangtze River. Like plenty of sunshine, but also withstand half-shade. It is suitable to be cultivated in sandy loam with good drainage and deep soil layer. Like warmth, it is suitable to grow in loose and fertile sandy soil.

Second, the morphological characteristics of torch flower.

The plant is 80-120 cm high and the stem is erect. Racemes bear hundreds of tubular florets, torch-shaped, Corolla orange-red, florescence from June to July. The leaves are linear. Capsule yellowish brown, fruiting in September.

III. Ecological habits of Torch Flowers

Torch flowers like warm, moist, sunny and sunny environment, but also resistant to semi-shade. Sandy loam with deep, fertile and well-drained soil is required. Appropriate amount of base fertilizer, phosphorus and potassium fertilizer should be applied before planting. After transplanting or ramet, the seedlings should be watered for 2-3 times, cut weeds and keep the soil moist in time, and resume growth after about 2 weeks.

IV. Cultivation techniques of Torch Flower

1. Ground planting

Sowing and raising seedlings in greenhouse in January, planting in open field in April, and flowering from July to August in summer. Appropriate amount of base fertilizer, phosphorus and potassium fertilizer should be applied before planting. After transplanting or ramet, the seedlings should be watered 2-3 times to weed in time and keep the soil moist. Strengthen the cultivation management, sowing seedlings or split seedlings can blossom in the second year. When the scape appears, it is necessary to apply 0.1% potassium dihydrogen phosphate external topdressing 2-3 times, each time at an interval of 7-10 days, or 1% 2% superphosphate topdressing once to enhance the stiffness of the scape and prevent bending. Increase irrigation before flowering, and stop watering after the flowers fade. If the flower is bitten by a beetle during flowering, 0.2% omethoate can be sprayed. Torch flower has strong cold tolerance, so open field cultivation should be properly covered with grass to keep warm in order to survive the winter safely.

two。 Colonization

Seedling height 10cm planting should be 2-3 potassium dihydrogen phosphate extra-root topdressing, each interval of 7-10 days, the concentration of 0.1%, should be replanted every 2-3 years, in order to promote the growth of new roots to promote cultivation. In the production of cut flowers, the florescence should be prolonged as much as possible, which can be controlled by sowing and transplanting by stages. The natural flowering period of torch flower is from late May to mid-June. If the seedlings sown in the previous year are transplanted and planted in April-June of the second year, they can blossom in September-October.

Fifth, the culture method of torch flower

Torch flower can be cultivated in open field or potted in many rows. The planting site should choose clayey loam with high and dry terrain, leeward and sunny place and rich in humus. Before planting, apply more mature organic fertilizer, increase phosphorus and potassium fertilizer, and then dig deep into the soil. The height of the seedling was fixed around 10cm, and the row spacing was 30cm × 40cm. After planting, the seedlings were watered twice, and then ploughed, loosened soil and squatted seedlings to promote the development of new roots. If sufficient water supply and topdressing are needed in summer, it will grow rapidly, and under the condition of 25-28 ℃ and sufficient sunshine, it can heading and blossom in about 5 months. When the flower stem appears, extra-root topdressing of 2-3 potassium dihydrogen phosphate should be carried out. Each time the interval is 7-10 days, the concentration is 0.1%, or 1% of the superphosphate of 2% concentration is used as topdressing of the soil, which can increase the stiffness of the flower stem and prevent bending. More basal fertilizer should be applied before dividing and planting in autumn to supplement the lack of nutrition in the plant. The overwintering ability of torch flower is closely related to the accumulation of nutrients in its body. After flowering, the residual flower branches should be cut off as soon as possible so as not to make it fruiting so as not to consume nutrients. In dry areas in winter and spring, water should be poured through before freezing, and plants should be covered with hay or fallen leaves to prevent drying and freezing death. It is late to remove the cold cover in early spring, so pay attention to the attack of cold in late spring to prevent plant damage.

Torch flower is a shallow root flower, the root system is slightly fleshy, the root hair is less, the root system is dense and clustered for too long, the number of root hair decreases, and the absorptive capacity decreases, so it must be replanted every 2-3 years. To promote the growth of new roots. The seedlings were watered twice when the seedlings were moved, and the seedlings were squatted under ploughing and loosening soil to promote the development of new roots. Appropriate amount of base fertilizer, phosphorus and potassium fertilizer should be applied before planting. After transplanting or ramet, the seedlings should be watered for 2-3 times, cut weeds and keep the soil moist in time, and resume growth after about 2 weeks. When the scape appears, it is necessary to apply 0.1% potassium dihydrogen phosphate external topdressing 2-3 times, each time at an interval of 7-10 days, or with 1% Murray 2% superphosphate topdressing once, to enhance the stiffness of the scape and prevent bending. Increase irrigation before flowering, and stop watering after the flowers fade.
