Boxwood in Hokkaido
Buxuzhi', a Euonymus japonicus variety in Hokkaido, has wide leaves, oval to wide oval, blunt top, thick leaves, annual growth of not less than 70 cm and few lateral branches.
Morphological characteristics of Euonymus japonicus in Hokkaido: Euonymus japonicus is an evergreen tree with leathery leaves, dark green front and light green back. In the cold winter, the leaves are green and there are no fallen leaves. Leaves ovate or oblong, 5-6 cm long and 4-5 cm wide. The leaf margin is shallow, and the petiole is about 1 cm long. Flowers are light yellow, with a diameter of 0. 1- 1 cm. The capsule is nearly spherical, with 4 shallow grooves and a diameter of 1-2 cm. The fruit is light green when tender, reddish brown on the sunny side, and the seeds are nearly spherical. 1 1 cm ripens, and the peel cracks automatically when it ripens.
Euonymus japonicus is a cultivated species of Euonymus japonicus, belonging to Euonymaceae, Euonymus japonicus, native to Japan. 1986 was introduced to Beijing by Chinese Academy of Forestry. After years of domestication, breeding and optimization, it has become an excellent new variety suitable for the climatic conditions in northern China.
Buxus japonicus in Hokkaido grows rapidly, with the highest annual growth rate of 170cm and the average growth rate of 70cm. The five-year-old seedlings are more than 3 m high, with strong top and obvious top edge, which shows excellent tree characteristics. Easy propagation, high survival rate of cutting, and rapid mass propagation.
Buxus japonicus in Hokkaido has good cold resistance and drought resistance, and its adult trees can tolerate the low temperature of -23.9℃, and its drought resistance is also better than that of ordinary Buxus japonicus. Strong ability to absorb harmful gases, strong ability to resist harmful gases such as sulfur dioxide, hydrogen and hydrogen fluoride. In winter, the crown of the tree is beautifully green, and the ripe fruit splits, exposing the red aril, and the green leaves support the red fruit, which is pleasing to the eye and of great ornamental value.
Suitable scope: Suitable for winter planting in cold and arid areas in northern China. In courtyard greening, it can be planted singly or in rows or groups.
Uses: Boxwood in Hokkaido is tall and straight, evergreen all the year round, resistant to pruning and shaping, and is an excellent variety of landscaping in small towns in northern China.
Muxiuqiu
Viburnum, Viburnum hydrangea, is a plant of Caprifoliaceae.
Distribution: It is native to the Yangtze River valley in China, and also distributed in Shandong and Henan.
Morphological characteristics: semi-evergreen shrubs, bare buds, branches, leaf north, petiole and inflorescence all have gray-white star-shaped hairs. The leaves are oval.
Growth habit: like light, slightly tolerant of shade.
Garden use: it is a traditional flower and tree that is deeply loved by people.
Propagation and cultivation: cutting. Layered and propagated by dividing plants.
Originated in China and Japan. I like warm, humid and semi-cloudy environment. The suitable growth temperature of hydrangea is 18 ~ 28℃, and the winter temperature is not lower than 5℃. It takes 6 ~ 8 weeks for flower buds to differentiate at 5 ~ 7℃, 20℃ can promote flowering, and maintaining 16℃ after flowering can prolong flowering. But the high temperature will make the flowers wither quickly. Pot soil should be kept moist, but it should not be watered too much, especially in rainy season, to prevent root rot caused by waterlogging. Indoor potted plants should be slightly dry in winter. If it is too dry and humid, leaves rot easily. Hydrangea is a short-day plant, which is treated in the dark for more than 10 hour every day and forms flower buds in about 45 ~ 50 days. Usually, cultivation should avoid exposure to the hot sun, and 60% ~ 70% shading is the best. Loose, fertile and well-drained sandy loam is the best soil. However, the change of soil pH makes the color of hydrangea change greatly. In order to deepen the blue color, aluminum sulfate can be applied during bud formation. In order to keep pink, lime can be added to the soil. Commonly used branching, layering, cutting and tissue culture propagation. Propagation by ramets: it should be carried out before germination in early spring. Separate the rooted branches from the mother plant, pot them directly, water them too much, and maintain them in semi-shade, and then transfer them to normal maintenance after sprouting new buds. Layered propagation: it is carried out when the bud germinates and can grow after 30 days. The next spring, it can be cut from the mother plant, transplanted with soil, and can bloom in the same year. Cutting propagation: in rainy season. Cut off the upper shoots, about 20 cm long, and remove the lower leaves. The optimum cutting temperature is 13 ~ 18℃, and after cutting, 15 takes root. Pots of 15 ~ 20cm are commonly used for potted hydrangeas. Potted plants should be fully watered after germination in spring to ensure that their leaves do not wither. During the flowering period from June to July, fertilizer and water should be sufficient, and fertilizer should be applied every half month 1 time. When the light is too strong in midsummer, proper shading can prolong the flower viewing period. Remove the stems after flowering to promote the production of new branches. The color of flowers is influenced by soil pH, and the flowers in acidic soil are blue, while the flowers in alkaline soil are red. Change the pot once a year in spring. Prune properly to keep the plants beautiful.
