First, hang the Admiralty upside down.
The upside-down golden bell flower, also known as the bell flower, is very cute when it blooms.
First, the form:
The upside-down Admiralty is a perennial shrub with needle-like elliptic leaves, serrated leaves and opposite species tips. Flowers and plants are born, flowers are bell-shaped, petals change greatly, flower stalks are long, and there are many varieties of berries.
Second, the characteristics:
The upside-down admiralty originated in Mexico, and it likes cool and humid, but it is afraid of hot and high temperature. The growth temperature 15 ~ 25℃ will affect the growth of branches and leaves, and the branches and leaves will wither and die above 35℃. When the temperature is lower than 10℃ in autumn and winter, you should move indoors immediately. If the temperature drops to 5℃,
It should be adjusted to above 5℃ immediately, otherwise it will suffer from freezing injury. Second, the cultivation method of upside-down Admiralty
First, the soil choice of upside-down Admiralty culture
Potted soil mixed with sandy garden soil, humus soil and farmyard manure 1/3. Before entering the peak season every spring, we should change pots and soil, remove some pots and soil, cut off some old roots, and use larger flowerpots according to the plant size.
Then replenish the prepared basin soil. The soil should be loose, fertile and well drained. If there is water, plants can easily die because of rotten roots. We should loosen the soil properly in spring and autumn. Second, the fertilization method of upside-down Admiralty culture
The golden bell hangs upside down like fertilizer. When potted, 4 parts of humus soil, 3 parts of garden soil, 2 parts of river sand, and decomposed cake fertilizer powder 1 part are mixed to form culture soil, and no additional base fertilizer is needed to avoid root rot. Turn over the pots and change the soil every spring 1 time. The upside-down Admiralty grows rapidly and can bloom continuously, so during the growing period, apply 1 times 10% ~ 15% cake fertilizer or dilute liquid fertilizer with nitrogen and phosphorus at a concentration of 0 every 7 ~ 10 days. 1%~0。 2% urea water plus 0. 3%~0。 5% calcium superphosphate soaking solution, or 0. 1%~0。 2% urea water plus 0. 1%~0。 2% potassium dihydrogen phosphate fertilizer water. If there is insufficient nutrition, it will be difficult to bloom once.
Third, the requirements of light and temperature for upside-down golden bell culture
Plants should be placed in a ventilated and cool place in summer, and the suitable temperature is 15 ~ 25℃. The room temperature should be kept above lO℃ in winter, and it may freeze below 5℃. When the autumn temperature is lower than 10℃,
It should be kept indoors for maintenance. The light should not be too strong, especially in summer, and long-term direct sunlight should be avoided to prevent the leaves from curling and dying.
Fourth, the watering method of upside-down Admiralty culture
Pay attention to watering, and keep the soil moist during the growing period. Generally, we should master the principle of "seeing dry and seeing wet" when watering the golden bell. If the soil in the basin is too wet or too wet when flowering, it is easy to cause buds, flowers or leaves to fall.
Long-term over-wetting of basin soil can easily lead to rotten roots, yellow leaves and even plant death. When the room temperature is lower than 10℃ in winter, watering should be strictly controlled and fertilization should be stopped to prevent root rot. After each fertilization and watering, loosen the soil and ventilate in time. Fifth, the method of hanging upside down the golden bell to spend the summer safely
Safe summer is the key to maintain the upside-down admiralty, and it should be moved indoors or in a cool and ventilated place in summer. Hanging upside down admiralty likes cool climate, and is most afraid of high temperature, exposure and rain in summer. When the temperature exceeds 30℃, the metabolic activity is slow, the growth is in a stagnant state, and defoliation and root rot are often prone to occur. If effective measures are not taken in time, the whole plant will die. Maintenance and management measures for upside-down admiralty in summer are as follows:
(1) Shade the sun in summer to avoid direct sunlight; Strengthen ventilation and keep it in a cool and ventilated place.
(2) Cooling and humidifying, family potted plants, you can move the flowerpot to a cool place with ventilation and shelter from rain, or put it on the balcony or eaves where you can see scattered light slightly in the north, or put it in a cool and ventilated place indoors with a little sunshine. When the temperature exceeds 22℃, spray water on the leaves 1 ~ 2 times a day; When the temperature exceeds 25℃, spray water for 3 ~ 4 times, and spray water for 2 ~ 3 times on the ground around the flowerpot to reduce the temperature and increase the air humidity.
(3) When the temperature of fertilizer and water exceeds 25℃, fertilization should be stopped to avoid root rot. Generally, in the high temperature season from June to August, fertilization should be stopped, watering should be controlled, and the pot soil should be slightly dry. If the basin soil is often too wet or stuffy and not ventilated. It will cause the leaves of plants to turn yellow and brown, and even the rotten roots will die.
(4) Prevent rain, which may easily lead to rotten roots and fallen leaves.
(5) Cultivate new seedlings. The perennial plants hanging upside down in Admiralty are sensitive to high temperature, but their seedlings have strong heat resistance and will not shed leaves in rainy days. Therefore, transplanting and cultivating new seedlings every year is beneficial to their safety in summer. This is a more positive measure.
Sixth, the coring method of upside-down Admiralty culture
Picking the heart at the right time is an important measure to make the upside-down golden bell flourish. In spring and autumn, the plants should be topped and pitted, so as to promote their branching, make the plants plump and increase the flowering amount. Because the upside-down golden bell has the habit of planting buds between the axils of new leaves, new buds can germinate, grow more branches and flowers, and the plant type is full.
Picking should start from the seedling stage. Generally, when the seedlings grow to about 10 cm, the first coring is carried out to promote branching. About 30 days after the first coring, when the new branches grow 6-8 leaves, the second coring is carried out, with about 5 lateral branches per plant, and the redundant lateral buds are removed. After the autumn is cool, the excessively long branches can be cut short, and the excessively dense branches can be thinned out, so as to promote the development of robust new branches. Water should be controlled after each pruning, and normal watering should be carried out after new branches grow in the axils of leaves. In the season with suitable growth, the new shoots can bloom again after 15 ~ 20 days, so the flowering period can also be prolonged by coring many times. Usually, it is pruned again after flowering in early summer, and then the plant shape is appropriately pruned when it enters the room in autumn to remove excess new buds.
Third, matters needing attention of hanging upside down Admiralty culture
Falling flowers and buds often occur in lodging Admiralty, which is mainly caused by improper cultivation and management. It should be noted that:
First, hanging upside down likes a cool and humid climate. The optimum growth temperature is 10 ~ 28℃. It is in a semi-dormant state under hot and dry conditions. In summer, shading and watering should be used to cool down and increase air humidity, otherwise leaves, buds and flowers will fall.
Second, light. The upside-down golden bell should be cultivated in sunny places in spring and autumn, otherwise it will affect the development and flowering of flower buds due to insufficient light. Shade in summer to avoid leaf burn affecting flowering.
Third, fertilizer and water management. Because the upside-down golden bell has the characteristics of fast growth and many flowers, it is necessary to fertilize and water more in spring and autumn. In summer, control fertilizer and water, shade and cool down.
Fourth, pest control. It is vulnerable to scale insects, aphids, red spiders, whiteflies and leaf spot diseases in summer. In the process of maintenance, attention should be paid to ventilation, adequate light and reasonable water and fertilizer management to improve plant resistance. When pests occur, 20% dicofol EC can be sprayed 800 times to kill red spiders, 40% omethoate EC 1000 times to kill scale insects, aphids and whiteflies, and 50% fungicide 1000 times to control leaf spot.
5. To cool down and humidify, the family potted plants can be moved to a cool place with ventilation and shelter from rain, such as a place where scattered light can be seen under the balcony or eaves in the north, or a cool and ventilated place where sunlight can be seen indoors. At the same time, when the temperature exceeds 25℃, spray water 1-2 times a day, spray water 3-4 times when the temperature exceeds 30℃, and spray water 2-3 times around the flowerpot to reduce the temperature and increase the air humidity.
Six, to prevent rain, rain is easy to cause roots and leaves to rot.
Seven, cultivate new seedlings The old perennial plants hanging upside down are sensitive to high temperature, and the seedlings are more heat-resistant and will not shed leaves in hot summer. Therefore, transplanting and cultivating new seedlings every year is conducive to their safe summer, which is a more active measure.
Fourth, the focus of saving.
One is to place plants in a cool, ventilated, cool and rain-proof place; Spray water on the leaves and the ground several times a day to reduce the temperature and increase the air humidity.
The second is to stop watering and fertilizing perennial plants and successfully pass the dormancy period. Plants should enter the room before the first frost and leave the room after Tomb-Sweeping Day, and the room temperature should be kept above 5℃. In case of cold current, snowstorm and outdoor icing, it is best to move back indoors.
Fertilization should be stopped to avoid root rot. Generally, in the high temperature season from June to August, fertilization should be stopped, watering should be controlled, and the pot soil should be slightly dry. If the basin soil is often too wet or stuffy and not ventilated. It will cause the leaves of plants to turn yellow and brown, and even the rotten roots will die.
