2 growth habit editor
Warm light: dragon boat flower is more suitable for high temperature and sunny environment, and likes damp heat.
Dragon Boat Flower Album (16)
Our climate can't stand the low temperature. The optimum growth temperature is 23~32℃. When the temperature is lower than 20℃, its growth is weakened and its flowering is obviously reduced. But if there is plenty of sunshine, there are still a certain number of flower buds. When the temperature is lower than 10℃, its physiological activity decreases and its growth is slow. When the temperature is lower than 0℃, freezing injury will occur. [3]
Soil: Dragon Boat Flower likes acidic soil, and the most suitable soil pH value is 5~5.5. The soil with good drainage and good fertility preservation can grow well, and the best cultivated soil is sandy loam or humus loam rich in organic matter. If the soil is alkaline, the growth of dragon boat flower is hindered and stunted. [3]
3 distribution editor
Dragon Boat Flower is native to China, Myanmar and Malaysia. China is mainly distributed in Fujian, Guangdong, Hongkong and Guangxi. Vietnam, Philippines, Malaysia, Indonesia and other tropical regions. [ 1] [4]
4 breeding method editing
Dragon boat flowers can be propagated by sowing, layering and cutting, but cutting is generally used. [5]
Cutting propagation method
It is best to do it in June ~ July. Select semi-mature branches, the length of which is 10~ 15cm, and insert them into the sand bed. The suitable temperature after insertion is 24~30℃ and 40 ~ 30℃.
Dragon Boat Flower [2]
Rooted in 50 days. Soaking cuttings in 0.5% indolebutyric acid solution for 3 ~ 5s can shorten the rooting period. [6]
1, environmental factors affect rooting.
The suitable bed temperature for cutting rooting is 25~35℃, which is slightly lower than the bed temperature, about 23 ~ 35℃. Cutting time is the best in late spring and early summer. In general, natural light can basically meet the needs of cutting and rooting. However, during the high temperature period in tropical summer, because cutting is easy to wilt, it is best to use spray seedling, and shading treatment should be carried out within a few days of cutting, from the initial shading rate of 50%~60% to 40%~50%, and shading should be removed after rooting. [3]
2. Cutting of cuttings
The quality of cuttings will not only affect the quality of seedlings, but also affect the subsequent growth. For the requirements of excellent cuttings,
Dragon Boat Flower [2]
Shoots and cuttings are cut in spring and summer. At this time, the plant is sprouting a large number of tender strips, which grow to 8~ 12cm, and are cut when there are no flowers. The best time is sunny evening, choose healthy branches with neat cuttings. Generally, the fresh weight of the cut section is 3 ~ 5g, the length is 10~ 14cm, and the diameter of the cut section is above 3mm. The pruning part is semi-hard branch, which is usually combined with strong pruning of lateral branches or main branches. [3]
3. Drilling cuttings processing
Different varieties have different difficulty in rooting. Generally, short varieties with small leaves are easy to take root, and cuttings can take root well and quickly without treatment. However, for tall varieties with large leaves, it is generally difficult to take root. Treatment with growth hormone substances such as IBA or NAA before cutting can significantly promote rooting. During treatment, low concentration rooting agent can be used for long-term soaking or high concentration instant soaking. [3]

4. Cut the soil
The correct selection of cutting soil has great influence on the rooting rate and seedling rate of cutting. The standard of cutting soil is water retention, strong permeability and cleanliness. At present, there are perlite, vermiculite and river sand. The above materials can be used alone or in combination. River sand has good permeability, but poor water retention, so perlite is generally mixed. If used alone, it is suitable for intermittent spray cutting. Single perlite is suitable for summer drought and strong sunshine. In Hainan, it is best to mix river sand and perlite according to the ratio of 1: 1, or spread a layer of perlite with a thickness of 2~3cm on the sand surface with river sand as the bottom. [3]
sow seeds
Seed collection in winter and sowing in spring. The optimum temperature for germination is 22~24℃, and it germinates 20~25 days after sowing. When 3~4 pairs of true leaves grow, the seedlings can be moved to 8cm pots. [6]
floor
Plants with many branches and dense branches can be peeled from the top 20 cm and wrapped with peat and film, which can heal and take root in more than 2 months. [6]
5 cultivation technology editor
land
The cultivation soil of Dragon Boat Flower is sandy loam or humus loam, which has good drainage, strong acidity and rich organic matter. Before transplanting, the soil layer is deeply turned over to break up the big soil, and according to the soil structure, the river sand and organic fertilizer soil are mixed and fully mixed to achieve the soil conditions suitable for the growth of the dragon boat flower; The nutrient soil for pot seedlings or bag seedlings is fully mixed with 1 part garden soil, 1 part river sand and 1 part organic fertilizer soil, or made of pond mud, river sand and coconut bran in the ratio of1:1:0.5. [3]
transplant
Transplanting should be carried out after cuttage takes root. Generally speaking, when the root length is less than 2 cm, it should be removed from the cutting seedbed. If the root length is more than 2 cm,
Dragon Boat Flower [2]
It is easy to cut off roots when taking seedlings, which affects the slow rooting and initial growth of seedlings. Generally, the cutting diameter of dragon boat flowerpots is 10~20cm. According to the size of the seedlings and the number of plants cut, the cut plants must be neat and of the same color. Cutting pots: change pots every 1~2 years 1 time, and trim and cut off diseased branches and weak branches. Whether it is pot cutting or ground cutting, you should choose a sunny place. The ground cutting of dragon boat flower is a forming block, which has quick effect. Generally, pot seedlings or bag seedlings with the age of 1~3 years are selected, which can be carried out all year round and planted in deeper soil layers. When potted in winter, dragon boat flowers must be kept above 15℃ to continue to grow. Too low a temperature will cause defoliation. [3]
Fecal fluid
Ardisia likes humidity, but is afraid of dryness. The stems and leaves need enough water during the growing period, and keeping the basin soil moist is beneficial to bud germination and leaf growth. However, if it is too humid for a long time, it will easily cause some root rot and affect growth and flowering. If the soil is too dry or sometimes dry and sometimes wet, and the water supply is not timely, defoliation will occur. [3]
Spring, summer and autumn are the growth period and flowering period of the dragon boat flower, so it is necessary to strengthen the management of water and fertilizer, and apply fertilizer 1 time every 30~40 days. All kinds of organic fertilizers or inorganic compound fertilizers are ideal. Planting in the northern region, applying "Huiyou" 2 1-7-7 acid fertilizer 1 time every half month, if the leaves are found to be light green, thin and dull, and the flowers are few in color, it is insufficient light, not lack of fertilizer and water.

6 pest control editor
leaf spot
This disease is caused by Fusarium. The pathogen overwinters on diseased flowers or falls into the soil with diseased leaves, and is spread by wind, rain or water in the following year. [3]
Prevention and control methods:
(1) Horticultural control: it meets the growth conditions of dragon boat flowers, likes sunny, warm and humid climate, and likes loose and fertile acidic soil.
(2) Chemical control: spraying drugs at the initial stage of the disease, and the drugs can be 800 times suspension of 50% thiophanate-methyl; Or 500 times of 50% carbendazim wettable powder; Or 10% antibacterial agent 40 1 acetic acid 1000 times. [3]
anthrax
The disease mainly harms leaves, and pathogenic bacteria overwinter in diseased parts or diseased leaf residues. When the conditions are suitable, it spreads through wind and rain and invades from the wound to carry out primary infection. [3]
Prevention and control methods:
(1) Horticultural control: remove diseased leaves and reduce the source of infection. The spacing between flowerpots or plants is appropriate to ensure good ventilation and light transmission.
(2) Drug prevention: spraying drugs before onset, and the drug can be 1: 1: 200 times of Bordeaux solution; Or 800 times of 50% carbendazim wettable powder and 75% chlorothalonil wettable powder; Or 500 times of 25% carbomer wettable powder. The above chemicals are sprayed every 10 day/time, and the control is continued for 3-4 times. [3]
scale insect
Once the scale insect occurs, it is very harmful, and prevention is the main thing. Once scale insects are found, they should be prevented in time without delay. Scale insects will not only hinder the growth of plants and cause other diseases, but also affect their ornamental value. [3]
Prevention and control methods:
(1) Horticultural control: It is forbidden to bring in or bring out the seedlings with insects, and increase the application of organic fertilizer and compound fertilizer in time to enhance the seedling vigor and improve the insect resistance.
(2) Drug control: root application of internal absorption granules, such as 3% carbofuran granules, with the dosage of 0.5 ~ 1g buried in a flowerpot with a diameter of 20cm, can last for 40~60 days. Spraying pesticides in time at the peak of egg incubation can be 40% omethoate EC 1500 times and 50% chlorpyrifos EC 1000~ 1500 times. [3]
aphid
When aphids harm young stems and leaves, 2.5% EC 1200 times solution should be sprayed. [3]

Scenery, windowsill, balcony and various room furnishings; Dragon boat flowers in tropical areas are especially suitable for open planting, and are used for plant selection in courtyards, hotel communities, roadsides and scenic spots. Widely used in gardens, single planting, cluster planting, row planting and stick planting have their own characteristics. [3]
Plant these small pieces to form a big ribbon-shaped color block.
In the blooming season, dragon boat flowers are red as fire, orange as chardonnay, flowers floating on leaves, long flowering period and rich colors, including red, yellow, orange and white. Therefore, it is often planted in a large area in the garden. In the middle of the isolation belt next to the road or the driveway, large color blocks are planted, which is very imposing and unusual. With the different seasons and colors, colorful ribbons appear in front of people. The varieties suitable for flower belt are dwarf dragon boat flower series. In an open and flat area, it is a common practice to assemble small plants into jumping large color blocks in landscaping. [3]
Ornamental planting of dragon boat flowers [2]
Flower bud planting
The varieties with excellent plants in dragon boat flowers grow slowly and do not need to be pruned frequently. They belong to excellent shrubs with low maintenance cost. They are often planted and trimmed into strips in the garden, which are green when they bloom and green when they don't bloom. With different colors, they are very elegant and varied. This kind of greening usage is common on both sides of stairs, along walls, along roads and on the edge of grass. It not only beautifies the environment, but also plays a guiding role. It can also be used as a green pheasant to prevent people from crossing and trampling on the lawn. [3]
Trim a shape to form a pattern
In the open lawn and street green belt, in order to break the single style of lawn, many short bamboos are often planted on the lawn, combined with pruning, to form various patterns and patterns. Short dragon boat flowers with slender leaves are very suitable for modeling patterns. In many scenic spots, it is very common to use dragon boat flowers to construct paintings.

The dragon boat flower cultivated in China should be cultivated as an ornamental plant in the south yard at the end of 16. At the end of 17, Taiwan Province Province introduced the dragon boat flower from Guangdong for the first time. In the 1920s, Guangdong and Taiwan Province introduced new cultivated varieties from Singapore, and in the 1980s, they introduced new hybrid varieties from Europe and America, which enriched the cultivated varieties of dragon boat flowers in China, and more ornamental plants were potted in the southern courtyards.
