How to raise the Golden Bell upside down, the breeding methods and precautions of the Lantern Flower / hanging Bell Begonia; Encyclopedia of knowledge of hanging the Golden Bell upside down (Latin name: Fuchsia hybrida Hort. Ex Sieb. Et Voss), alias: Lantern flower, hanging bell begonia. Perennial subshrubs with erect stems. 50-200 cm tall, 6-20 mm thick, much branched, pubescent and glandular hairy, glabrous when old, young branches reddish. Leaves opposite, ovate or narrowly ovate, 3-9 cm long and 2.5-5 cm wide. Like cool and humid environment, afraid of high temperature and strong light, fertile, loose slightly acidic loam is suitable, the winter temperature is not lower than 5 ℃. Native to Mexico, widely cultivated all over the world, widely cultivated in China, especially in the north or in the northwest and southwest plateau greenhouse. Potted plants are suitable for guest rooms, flower racks, desk embellishments, and bottles with clear water, which can not only be watched, but also take root and reproduce. Upside down Admiralty growth habits: like cool and humid environment, afraid of high temperature and strong light, avoid hot and stuffy heat and rain in the sun. With fertile, loose slightly acidic soil, and should be rich in humus, good drainage. Winter requires warm and humid, sunny, well-ventilated; summer requires dry, cool and semi-overcast conditions, and maintain a certain degree of air humidity. The growth was very slow when the summer temperature reached 30 ℃, and withered and died in large numbers at 35 ℃. If the winter temperature is not lower than 5 ℃ and the weak temperature is less than 5 ℃, it is easy to suffer frost injury. Inverted Golden Bell varieties: coral Red inverted Golden Bell (var.corallina): tufted dwarf varieties with dark leaves and large whorls of flowers; calyx red, Corolla pansy. Spherical short tube upside down Admiralty (var.globosa): branches glabrous, veins red, pedicels long sepals crimson; petals bright blue and pansy, about 1 inch of calyx lobes in length. Heterochromatic short tube inverted Admiralty (var.discolor): clump dwarf variety with dark purplish red branches. Leaves small, 3 whorled, ovate-lanceolate. Flowers small, numerous; calyx red, tube slender; petals obtuse, shorter than calyx lobes. Ray's short tube hangs the golden bell upside down (var.riccartonii): the branches are slender and drooping. The leaves are very small. Flowers long and drooping; calyx tube bright red, petals pansy. White calyx upside down Golden Bell (F.Alba~coccinnea): a cultivated hybrid. Calyx tube white, longer, lobes revolute, petals red. Long tube upside down Admiralty (F.fulgens): the plant is 1 to 2 meters tall, sparsely pilose, with tuberous tubers at the bottom. The branches are slightly succulent, reddish, with longer leaves, 10 cm long and 5 cm wide. Calyx tube long tubular, base slender, bright scarlet, 5 × 7.5 cm long. Petals short, 1 cm long, crimson. Three-leaf inverted Admiralty (F.tri-phylla): low tufted shrub, 20-50 cm high, leaves often 3 whorled, green, bright reddish brown on the back, densely tomentose on the veins. Flowers scarlet, 4 cm long, calyx tube long, enlarged above, petals very short. The main method of propagation is stick insertion propagation. Except for hot summer, it can be carried out all year round, and spring rooting is the fastest. Spring is from March to May and autumn is from August to September. Select strong growing branches, each segment has 2 to 3 stem nodes, leaving an upper pair of leaves, the base is obliquely cut near the node, soak all in 0.1 potassium permanganate solution for 30 seconds, expose the leaves upright, and soak the base for 30 minutes. After taking it out, brush it with clean water, then keep it in clean water for 24 hours before inserting the rod, and the density should not cover each other with leaves. Cuttings should be transplanted as soon as possible after rooting. Generally speaking, the root length should not exceed 2 cm. First, the cuttings were planted in a small bowl with plain soil (50% garden soil and 50% river sand) to promote root growth. Vegetarian soil has little irritation to new tender roots and is beneficial to survival. Pour water twice after planting, place it tightly in a shallow basin and maintain it in a semi-shady place. Field management light likes semi-overcast environment, but there are different requirements for light in different seasons. Winter and early spring, late autumn need full sunshine, early summer and early autumn need half-day sunshine, hot summer and midsummer should be shaded. Temperature upside down Admiralty grows at a temperature of 10-28 ℃, no more than 30 ℃ in summer, and withered and died in large numbers at 35 ℃. Therefore, the cooling work should be done well in summer; sufficient sunshine is required in winter, and the culture temperature should not be lower than 5 ℃, otherwise it will cause frost injury and heat preservation measures must be taken. Humidity spray water to the leaves many times a day, and sprinkle water on the ground to reduce the temperature and increase the humidity of the air. Fertilization due to the rapid growth of upside down Golden Bell, many times of flowering, so in the growing period to master the frequent application of thin fertilizer, about every ten days to apply thin cake fertilizer or compound fertilizer. The basin soil should be dry before fertilization; spray water once with a fine sprinkler after fertilization to prevent the leaves from rotting with fat and water. Fusarium wilt and rust often occur in pest control. 1000-fold solution of 10% acetic acid solution (antimicrobial agent 401) was applied to the soil to control Fusarium wilt. Due to poor ventilation, aphids, scale insects and whitefly can be sprayed with 1000 times of omethoate EC.

A brief introduction to Lantern Flowers

Lantern flower, also known as inverted Golden Bell, hanging Bell Begonia, is a perennial herbaceous flower, it has a wide variety, the main colors are red, purple, white three varieties. Although it is delicate and beautiful, it can not stand the scorching of the summer sun. Sexual preference for cool, humid climate, growth temperature of 10 ℃-25 ℃, sufficient sunshine in winter and semi-overcast environment in summer. When the summer temperature exceeds 38 ℃, the metabolism is slow and the growth is stagnant. The phenomenon of fallen leaves and rotten roots often occurs at this time. If no effective measures are taken, the whole plant will die.

Key points of maintenance of Lantern Flowers

[soil]: like loose sandy loam with good drainage.

[moisture]: water once in 2-3 days in winter and rainy season, once a day in autumn and sunny days, and control moisture in semi-dormant summer to prevent the occurrence of defoliation and rotting roots.

[Rizhao]: like the sunny environment, the lack of sunshine is easy to grow, resulting in a reduction in flowering.

[fertilizer]: sufficient organic fertilizer was applied before planting, nitrogen fertilizer was controlled in the early growth stage, overgrowth was prevented, and phosphorus and potassium fertilizer was applied at flowering stage.

[temperature]: the suitable temperature for growth is 15-25 degrees. If the temperature exceeds 30 degrees, it will enter a semi-dormant state, and not less than 5 degrees in winter.

Propagation techniques of Lantern Flowers

[cutting propagation]

It is often used for softwood cutting in late spring and early autumn, or old wood cuttings with branches from last year in early spring. Is used for cutting nutrient soil or river sand, peat soil and other materials. Due to the limited conditions, it is difficult to get an ideal cutting substrate, so it is recommended to use the prepared and sterilized cutting substrate provided by this station; medium and coarse river sand is also fine, but rinse with clean water several times before use. Do not use sea sand and river sand in saline-alkali areas, they are not suitable for the growth of flowers and plants.

When the tender wood cuttings were carried out, the sturdy branches of the current year were selected as cuttings when the plants were growing vigorously from the end of spring to early autumn. After cutting off the branches, select the sturdy parts and cut them into segments 5-15 cm long, each with more than 3 leaf nodes. When cutting cuttings, it should be noted that the upper cut is cut flat at about 1 cm above the uppermost leaf node, and the lower cut is about 0.5 cm below the lowest leaf node, and the upper and lower cut should be flat (knife should be sharp).

When hardwood cuttings are carried out, after the temperature rises in early spring, last year's robust branches are selected as cuttings. Each cuttage usually retains 3-4 nodes, and the cutting method is the same as that of softwood cuttings. The optimum temperature for rooting of cuttings was 20 ℃ ~ 30 ℃, which was lower than 20 ℃, the rooting of cuttings was difficult and slow, when the temperature was higher than 30 ℃, the upper and lower cuttings were easy to be infected and rotted by bacteria, and the higher the temperature, the greater the proportion of rot. When there is a low temperature after cutting, the heat preservation measure is mainly to wrap the flowerpot or container used for cutting with thin film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings, to cover 50-80% of the sun, and at the same time, spray the cuttings 3-5 times a day, with more times of spraying when the temperature is higher in sunny days, lower temperatures and higher temperatures in rainy days, but less or no spraying times.

The relative humidity of the air must be kept at 750.85% after cutting. The basic requirement for cuttings to take root is to ensure that cuttings are fresh and tender and can be used to produce rooting substances before they take root. However, cuttings without rooting can not absorb enough water to maintain their water balance, so it is necessary to reduce the water evaporation of cuttings by spraying: under shaded conditions, the cuttings are sprayed 3-5 times a day. The higher the temperature in sunny days, the more the times of spraying, the lower the temperature in cloudy and rainy days, the less or no spraying. But with excessive spraying, cuttings are easy to be infected by bacteria and rot, because many kinds of bacteria exist in the water. Cutting propagation is inseparable from sunlight, because cuttings continue to carry out photosynthesis to produce nutrients and rooting substances to supply their rooting needs. However, the stronger the light, the higher the temperature in the cuttings, the more exuberant transpiration of cuttings, and the more water consumed, which is not conducive to the survival of cuttings. Therefore, after cutting, the sun must be shaded by 50% to 80%, and then gradually removed after the root system grows: remove the sunscreen at 4:00 every sunny day, and cover it before 9:00 the next day.

Striping propagation

Select a strong branch and peel off the bark from about 15cm to 30cm below the top. The width of the peeled wound is about one centimeter, and the depth is limited to just peeling off the skin. Cut a piece of film 10 cm 20 cm long and 5 cm 8 cm wide, put some wet garden soil on it, and wrap it around like a wound. The upper and lower ends of the film are tightly tied and bulged in the middle. Take root in about four to six weeks. After taking root, cut off the root system along the edge of the branch to form a new plant.

Upper plate transplanting

When the small seedlings are installed in the pot or the large plants that have been raised for several years are transferred to the basin, a coarse-grained substrate 2cm thick is first put into the bottom of the basin as a filter layer, which is sprinkled with a fully mature organic fertilizer as the base fertilizer, with a thickness of about 1cm to 2cm, and then covered with a thin layer of matrix, which is about 1cm thick, and then put into the plant to separate the fertilizer from the root system and avoid root burning. You can choose one of the following substrates for potting: vegetable garden soil: slag = 3RV 1; orchard soil: medium coarse river sand: sawdust (dregs) = 4RU 1v 2; or one of paddy soil, pond mud, and rotten leaf soil. Pour water once after putting on the basin and keep it in a shaded environment for a week. When transplanting the seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as the base fertilizer (base fertilizer), the thickness is about 46.6 cm, and then cover a layer of soil and put it into the seedlings to separate the fertilizer from the roots and avoid burning roots.

Control methods of diseases and insect pests

1. Grey mold

Botrytis cinerea occurs in rainy weather or when there is too much nitrogen fertilizer or not enough light. It mainly harms stems, leaves and flowers, resulting in water-like spots on the affected parts. If it is not prevented in time, the hyphae will gradually expand and be covered with gray hairs, and in serious cases, the plants will die.

Solution: at the initial stage of the disease, 65% zinc or 50% carbendazim and other new agents with 500 times solution were sprayed every 7 to 10 days, continuously for 3 times, and pay attention to ventilation and light, so as to make the plant grow well and improve the plant's disease resistance. After the disease, the diseased branches and leaves should be cut off and treated in time to reduce the source of the disease.

2. Powdery mildew

Powdery mildew mainly harms stems, leaves and buds. After being infected, there is a layer of white powder on the surface, which shrinks the leaves and makes the flowers smaller.

Solution: pay attention to ventilation and light, increase the application of phosphorus and potassium fertilizer, improve plant disease resistance. After the onset of the disease, spray 70% Tuobu body liquid or 2500 times liquid strychnine or other appropriate agents in time, spray every 10 days, spray 2 times 3 times continuously.

Lantern Flower Summer Guide

[summer shade] enter the summer, if the temperature is more than 30 ℃, to avoid the strong sun exposure, during the day can be moved to the balcony under the balcony in a cool and ventilated place, and then moved to the balcony after sunset (preferably under the shade shed or tree shade). Move the plant from the south balcony to the north balcony in advance to avoid the sun. Put the pot plant in a larger bamboo basket or cardboard box, surrounded by soft pot soil to prevent the flowerpot from being directly baked by the sun.

[heating and cooling] put half or the whole brick into the container, fill the container with water (the water should be higher than the brick surface), and then put the pot plant on the brick to cool down for a long time. Place the pot plant downstairs in a place of ventilation and shelter, dig a small pit in the ground, bury the plant in the soil, and wait until autumn to put the plant indoors. Once the pot plant is heated by the hot sun, it must not be watered on the leaves and in the flowerpot before the heat is dissipated, so as to prevent uneven heat and cold, resulting in accidental damage. During the period of heat prevention and cooling, due to the reduction of light, watering should be controlled, do not be too frequent, and always keep the basin soil moist.

[prevent rain] Summer is a rainy season, before it rains, put the potted plants in a place of shelter from the rain, and if it is too late to move the flowerpot in case of thunderstorm

The stagnant water in the basin should be poured out in time. If the basin is still too wet at this time, you can use burnt charcoal to sprinkle on the surface of the basin soil to evaporate part of the excess water. If the water in the basin soil does not evaporate for a long time, and the basin soil is too wet, it is also easy to lead to fallen leaves and rotten roots, resulting in the death of the whole plant.
