Family Genus: Jing Tian Branch
Latin name: Kalanchoefedtschenkoi'RosyDawn'
Origin and habits:
Native to dry, sunny tropical areas of Madagascar.
Morphological characteristics:
Perennial succulent herbaceous plant, plant height 20-30cm, leaves alternate, flat, oval to oblong, margin toothed, blue or grayish green, irregular white, pink or yellow patches, new leaves It is even more colorful and beautiful. Loose cymes, florets red or orange.
Growth habits:
Can only tolerate extremely short-term low temperatures around 0°C, intolerant to cold and frost. Sex enjoys a warm and cool climate and is not resistant to hot sun.
Happened by astigmatism, it is appropriate for summer to be placed under sparse sunlight. The autumn grows vigorously and the inflorescences are extracted in winter.
In South China, it is generally safe to go winter in the open air. The northern part should be planted in pots and winter in greenhouses. When the temperature is above 13°C, it can normally bloom for viewing. The leaves are meaty, more drought resistant and do not require frequent watering.
Breeding:
The main use of cutting propagation, the best of May to June. Use a thick, plentiful top stem, cut 10–12 cm long, insert the incision in the sand bed after a little drying, and take root about 7–10 days. When the root length is 2-3 cm, transplant the pot. Can also be inserted into leaves, cut single leaves, cut out after drying, oblique plug sand basin, insert about 10 days after plugging new roots. After 30 days, plantlets were planted from the leaf base.
Cultivation:
Jade bells are short-day plants that bloom every winter. If the light is more than 12 hours, flowering will be postponed until early spring. After the spring flower replacement basin, and the entire plant pruning, control of plant height, promote multi-branching, in the emergence of new shoots, watering can be more. During the growth period, fertilizer is applied once a month, nitrogen fertilizer is reduced, and phosphorus and potassium fertilizers are applied more. The pattern of leaves is even more beautiful. Summer should be slightly shaded, but too shady, stems and leaves easy to grow long, soft, dark leaves lack luster. Winter room temperature at 10-12 °C, jade bell can normal flowering.
Pests and diseases:
Stalk rot and brown spot disease are common hazards and are sprayed with 65% dexamethasone WP 600 times. Insect pests are harmed by scale insects and whitefly, sprayed with 40% omethoate EC 1000 times.
application:
For the succulent plants of the foliage to share, pot planting, indoor viewing.
In the south of China, the flowering period is set to http://>New Year's Day, New Year and http://>Christmas, http://>Valentine's Day and other festivals. Strings of colored bells and exquisite branches give a festive atmosphere to the festival. .
Suitable for potted flower arrangement halls, in front of, flower beds, flower racks, etc., or planted flower beds, rockery, and so on, the scenery is particularly good.
It is also an important cut flower, giving a gift to others, expressing a soft spot. As an important ornamental plant resource, it is a kind of high prospect for the development of the rooting class.
After the erosion of the leaves of the same kind of plant, it can eliminate inflammation and detoxification, and it can be used to cure sores.

Jade Bell Roof Greening Technology
With the rapid development of the economy and the acceleration of urbanization, a high-rise building has been erected. The heat island effect of the city's stone-wet forest has become more apparent. In order to increase the area of ​​green space, the demand for roof greening and roof greening has become even stronger. At present, the application technology of roof greening mainly focuses on the improvement of planting substrates and new types of roofs, and the excavation and application of new wild greenery resources. These traditional greening technologies are applicable to the greening of a large number of old buildings in the city. It seems unsuitable because the roof load capacity of these buildings is small. For new buildings in the city, real estate developers generally have regulations and requirements for roof greening. Developers also need light weight because of economic cost considerations. With low-cost roof greening technology, these requirements cannot be solved by the current roof greening technology.
We provide a light-weight, low-cost sedum plant jade bell roof and its greening technology to solve the problem of greening the roofs of various types of cities in order to increase the urban green area and improve the environmental quality.
The roof greening technology implementation plan is as follows:
According to the area where the roof needs to be greened, a simple frame made of 2 to 3 cm thick wooden squares is used. The middle is divided into 40 to 50 cm long boxes, which are then fixed on the floor and covered with 15 to 20 mm thick frames. The mixture of peat soil and sandy loam soil is used as the growth layer of the plant, and the volume ratio of peat soil and sandy loam soil is 1:1. Then the following methods are used:
1. Remove rooted plantlets from grape stems of jade pendants and plant them in planting soil;
2. For cuttings, 4 to 5 cm long, thick and thick top stems were cut off, and the incisions were dried and inserted into the planting soil. Rooting took place in about 7 days.
3. When leaves are inserted, single leaves are cut, the incisions are allowed to dry, and the soil is inserted obliquely. New roots are grown about 10 days after planting, and plantlets grow for about 30 days. Watering keeps the soil moist for about 1 month, and it is properly pruned or picked. To control its height and promote branching, in addition, no other post-management.
The basic principle of Jade Bell Roof Greening:
From the aspect of physiological physiology, the plant is a succulent plant with strong drought-resistance-resistant, light-tolerant and light-weight soils, and is suitable for constructing light roof vegetation in thin soil layers; in terms of biological principles, the plant is low in vines. Roots and stems are easy to form a large number of rooted plantlets, stems, leaves can also be used as breeding materials, reproductive materials rich, easy to reproduce, easy to form new vegetation.
The greening technology has the following advantages:
1. With light weight, the selected matrix materials and planting materials are all lighter and smaller, and it is the construction of thin soil vegetation. As a result, the weight of roof vegetation formed is very light, and the increased roof load is very small;
2. The scope of application is wide, and the formed roof is light in weight and suitable for all types of roof greening;
3. The cost of construction and maintenance is low, the materials used are easy to obtain, the price is low, and the selected plants are strong in stress resistance and adaptability, and no post-management is required;
4. The technology is in line with environmental protection requirements. The materials used are all natural biological materials and do not cause damage to the environment.
5. Beautiful appearance, low plant height, only 20 to 30cm high, dense stems and leaves, bright and varied leaf color, flowering, standing inflorescences, blooming orange flowers, unusually attractive, very beautiful.
Jade Bell roof greening technology is generated due to the demand for improvement of the human settlement environment, and it is also a powerful measure for environmental protection. Therefore, the market has broad prospects.
