Osmanthus fragrans is a new variety with the most fragrant flowers, the longest flowering period and the fastest growth rate. Cinnamon, which was flourishing in those days.

It can grow to more than one meter, and when it blooms, the trees are full of yellow and silvery white, with flowers and fragrant fragrance, which is refreshing. The obvious advantage of osmanthus fragrans is that its stems protrude from the green leaves and can blossom all year round. Its flower buds can differentiate constantly, with the peculiar characteristics that the tender branches of spring buds will bloom, and the lignified old branches can also bud and bloom intensively. This ensures the long-term flowering and continuation of osmanthus fragrans. That year's two-leaf seedlings blossomed, which is incomparable to ordinary osmanthus. And has good adaptability, cold resistance and drought resistance, and is easy to plant and live.

Osmanthus fragrans' has wide adaptability and strong resistance. It likes neutral acidic soil rich in organic matter; Need a cool and humid microclimate, and have a certain cold tolerance. The germination period is earlier every year. In Northeast China and North China, potted plants can bloom normally; In the area south of Qinling and Huaihe River, it is safer to overwinter in the open field. In Fujian, Guangdong, Guangxi, Hainan and other provinces with high temperature all the year round, it is also more adaptable and can bloom as scheduled every year. According to statistics, each new shoot of' Osmanthus fragrans' has 3-4 pairs of leaves, and each leaf has 2-3 pairs of overlapping axillary buds. For other varieties of Cinnamomum cassia, each new shoot has only 2 ~ 3 pairs of leaves, and each leaf has only 1 ~ 2 pairs of solitary or overlapping axillary buds. This has resulted in the objective material basis of' Nissin Osmanthus fragrans' with a large amount of flowers and great flowering potential. The annual cumulative flowering period can reach more than 200 days, and the variety is named' Osmanthus fragrans'.

Edit the section on reproduction and cultivation.

brief introduction

Osmanthus fragrans' is usually raised by cutting. Because there are many flower buds in spring shoots, cuttings can only heal after cutting, but cinnamon can't.

Can take root, low survival rate. In recent years, the effect of autumn sowing is better; If seedlings can be transplanted once in the following spring, the survival rate of planting can be obviously improved. Sichuan Furong Seed Company cultivated young trees with DBH of 10cm. Shrub ball with crown diameter of 5m; The' Rixing' pile head and bonsai with a diameter of 5cm and a height of 50 ~ 100 cm can meet the market demand. The lowest limit temperature of the birthplace of osmanthus fragrans is -7℃, the highest limit temperature is 38℃, and the soil PH value is 6. It can also grow in neutral soil after trial planting. Sex likes fertile soil rich in organic matter, plenty of sunshine and cool and humid climate. Afraid of cold. The air is dusty and the environment is seriously polluted by sulfur dioxide, so it is difficult to grow and bloom normally. Choose a suitable environment when cultivating. Soil alkalinity can be mixed with 0.3% ferrous sulfate. The north should be protected and cultivated. Potted plants should be covered with plastic film in winter, and moved into a window with sunlight transmission indoors, and the temperature should be kept above 5℃. Osmanthus fragrans should avoid dust, and the leaves should be washed with clear water with a sprayer to keep them clean. The flowerpot should not be near places where harmful gases such as smoke and dust are concentrated. Osmanthus fragrans and other flowers and trees have the same requirements for water. Excessive soil moisture will affect growth and development. When it is found that the young branches and leaves are wilting, the flowerpot should be placed in a clear water basin with a quarter of the soil for about 1 hour, and then it can return to normal. Too much water can also lead to lack of oxygen and rotten roots. Cinnamon has few pests and diseases, and 800- 1000 times of quinalphos solution can be sprayed to control scale insects and red spiders.

Closed cutting technology

Osmanthus fragrans is a treasure of Osmanthus fragrans family, which is evergreen all the year round and has strong resistance. It grows in two directions (vegetative growth and reproductive growth), and the annual flowering period is more than 240 days (mature trees have obvious characteristics). The peak of flowering in China is from September of that year to the end of April of the following year, which is the first choice for landscaping and bonsai production. In recent years, it has quietly entered urban and rural bedrooms and hospital wards. Cinnamon can also extract high-grade natural plant aromatic oil, which has antibacterial, anti-inflammatory, antitussive, antiasthmatic, expectorant and antihypertensive effects. With the development and utilization of its medical and health care functions, its economic value will far exceed the ornamental value of gardens. 1. The key to the survival rate of seedbed preparation is closure, and the form of closure is shed and shed. If possible, the seedbed can be arranged in a greenhouse with light, or a reed curtain shed can be built outdoors (around). The seedbed should be higher than the ground 10 cm, and the drainage should be smooth. The width of a single brick is about 1 m, and the length depends on the cutting scale. The seedbed is made of bamboo (it's best to level it with tools, and both ends are sharpened and inserted into the soil, so that the grinding of stems is conducive to protecting the film). The distance between bamboo bows is 5-60 cm, and the height of the top of bamboo bow is about 0.6 m from the seedbed, so there is nutrient soil. The ph value is between 6.5 and 6.8, and 30% fine sand or river sand should be added to cohesive soil. It would be better if bio-enzyme bacteria could be applied to the seedbed. A 60 cm high shade shed (referring to the distance from the top of the shed to the top of the bamboo bow) should be built above the transplanting bed, and 80% shade net can be covered on the seedling shed for small-scale cutting. Drip-free film is the best film. 2. Cuttings can be treated with branches of the same year or many years (there is no obvious relationship between the age of branches and the survival rate), the length is 8- 10 cm, and pruning is not necessary. The rooting of Osmunda japonica can be at the node or not. Leave 2-3 leaves in the ear of the seedling, and cut 65,438+0/2 flat to avoid consuming nutrition and crowding. The cut branches should be sprayed indoors in time. Conditionally, it can be treated with 3a3 rooting powder 1-2 hours, or it can be made into paste. The row spacing of seedlings is 5cm× 10cm, and the depth is 1/2, with 200-250 plants per square meter. 3. Time and management: The spring sowing time is from May 5th to June 5th, and the autumn sowing time is from August 5th to September 20th. After planting, water is poured enough to cover the film once, and both sides are compacted with bricks or soil, and both ends can be compacted with bricks, which is beneficial to management. During high temperature, the film should be covered with sunshade net or reed curtain (open on cloudy days). Under normal circumstances, you can open the sunshade at 9: 00 in the morning and watch the light for half an hour. At the high temperature of 38℃, one end should be opened for ventilation and cooling. The optimum temperature in the greenhouse should be about 23℃, so the survival rate of seedling transplanting is the key to ensure the long-term stable and suitable temperature environment of seedling ear. It can take root in about 35 days. It is best to stay in bed for the winter because of poor lignification and weak anti-transplanting ability, which affects survival. 4. Pest control According to years of closed cutting experience, Osmunda japonica seedlings and mature seedlings are generally not easy to get sick, and the main pests are spiders. Seedlings can be sprayed with 4000 times dimethoate, and adult seedlings can be sprayed with 3500 times dimethoate in spring and autumn.

Rapid cultivation of bonsai

1. Before the roots germinate in spring, dig perennial ash trees in good shape up the mountain. According to the natural form of the original pile, cinnamon

Stereotype pruning. Be sure to leave 2-4 piles, and the cross section of each pile is 10- 15cm. Wrap the incision with a plastic bag, remove the plastic bag after germination to prevent water loss and dry the upper part of the pile. Then plant it in a flowerpot with the right caliber. After Tomb-Sweeping Day, when the new buds on the stem grow to 15cm, 2-4 stout buds (i.e., one for each rhizome) will be selected at a proper position, and all others will be wiped off. When the remaining branches are semi-lignified or lignified, they can be grafted, and the time is generally May-August. 2. Grafting method (1) Select rootstocks and scions with the same thickness by abutting, and use a sharp knife to cut a face with a length of about 3 cm and a thickness of 1/3 at the abutting part, and the section should be smooth. Put the two sections together, aim at the anvil and the eardrum, tie them tightly with plastic strips, and put them in the sun for normal management. It usually takes about 35 days to heal firmly, that is, the rootstock can be cut off at the upper part of the grafting site and the ear plants can be separated at the lower part. In the future, according to the growth strength, put the rope in time. This grafting method is from butt joint to untied rope, and the scion blooms normally. (2) Select semi-lignified or lignified laurel as the scion for abdominal grafting. Cut into 2-3 leaf segments, leave branches about 2 cm long at the lower end of the leaves, and cut off the leaves according to 1/3. Use a sharp knife to cut the lower end of the scion into a wedge with one side about 1.5 cm and the other side slightly shorter. Cut a tongue-shaped knife with a diameter of 1.5 cm at the grafting part of the rootstock. Immediately wedge the long cutting surface of the scion into the rootstock and align it with the rootstock and the ear cambium. Tie it tightly with plastic strips, put it in a plastic film bag and put it in the shade. After about 40 days, the joint healed firmly. Take down the plastic bag, remove the upper rootstock of the grafting part, and carry out normal management to make the buds grow and bloom normally. Unbind is the same as docking. 3. After successful maintenance grafting, the flowerpots can be ground together for maintenance. After soaking and decomposing once every half month, apply cake fertilizer and spray photosynthetic micro-fertilizer on the leaves. If leaf spot disease is found, it can be prevented by spraying 500 times of Kangkuling. If there is a red spider, you can spray 2000 times of Taoxiaoling to prevent it. When the outdoor temperature is about 0℃, you can move it indoors and put it in a place where the sun shines at level 5 or so. When the lowest outdoor temperature is above 3℃ in spring, it can be moved out of the house and then ground maintenance can be carried out. The author used this method to graft two osmanthus fragrans with 2-3 leaves on a ash tree for decades. After one year's maintenance, more than 100 leaves are basically shaped. 4. According to the natural form of the original pile, it can be trimmed into straight dry type, inclined dry type, horizontal dry type, dry type and exposed root type. No matter what kind of plastic surgery, we must not rush to achieve success, resulting in the consequences of haste makes waste. Special exposure, divided into several times, each time less exposure, remember not to worry too much. Generally, it can be trimmed and shaped in about two years. 5. After grafting, maintenance, pruning and shaping, the heel of Cinnamomum cassia can be replanted in the first-class bonsai basin, with ornaments, moss and flowerpots to appreciate the wonderful style of Cinnamomum cassia bonsai.

Edit this paragraph for planting and utilization.

Osmanthus fragrans' has a well-developed root system, rapid growth and green leaves all year round, which can be enjoyed. Long flowering period and beautiful shape. In Mid-Autumn Festival, National Day, New Year's Day and Spring Festival, four important festivals in China can bloom continuously, which shows that it is a rare evergreen fragrant flower tree species. Japanese Osmanthus fragrans' broke through the general understanding that Osmanthus fragrans doesn't bloom often, but it doesn't smell fragrant' and became a famous Osmanthus fragrans variety in China. This may be the main reason why' Nissin Osmanthus fragrans' series seedlings have been selling well in recent years. Osmanthus fragrans is a high-grade greening tree species with high ornamental value, which has the functions of greening, aromatization and colorization. Osmanthus fragrans can be cultivated into graceful small spherical trees, dense spherical shrubs, potted plants, or cut off branches and leaves to arrange flowers, which is called Osmanthus fragrans.
