Video pictures of sweet-scented osmanthus tree planting techniques

Garden uses sweet-scented osmanthus evergreen all the year round, luxuriant branches, autumn blossom, fragrance overflowing, can be described as "exclusive three autumn pressure group fragrance". It is widely used in gardens, often as landscape trees, including isolated planting, opposite planting, and forest planting in clumps. In Chinese classical gardens, sweet-scented osmanthus is often matched with buildings, mountains and stone machines, with tufted shrub plants planted near pavilions, platforms, buildings and pavilions. Old-style gardens are commonly used for planting. In ancient times, it was called "Shuanggui Dangtang" or "Shuanggui Liufang". If you plant sweet-scented osmanthus trees around the house or in front of the window, you can get the effect of "golden wind to send fragrance". Sweet-scented osmanthus has a certain resistance to harmful gases such as sulfur dioxide and hydrogen fluoride, and it is also a good green flower in industrial and mining areas. Sweet-scented osmanthus fragrance, containing a variety of spice substances, can be used to eat or extract spices. At present, China has formed areas with concentrated cultivation of sweet-scented osmanthus, such as Xianning in Hubei, Taoyuan in Hunan, Lu'an in Anhui, Guilin in Guangxi, Zunyi in Guizhou, and Wu County in Suzhou, Jiangsu. Because of the homonym of "Gui" and "Gui", people believe that sweet-scented osmanthus is a "rich tree". It has been hyped all over the country in recent years, and a tree can be sold for tens of thousands or even more than a hundred thousand yuan. saplings can also be sold for a few yuan. Medicinal value Osmanthus fragrans: Oleaceae. Evergreen trees, 3-15 m tall, branches gray. Leaves opposite, leathery, long elliptic, 6-12 cm long, 2-4.5 cm wide, entire. Flowers clustered in leaf axils, yellowish white, 4-lobed. Drupe oval, purple-black when ripe. Flower fragrance, extract aromatic oil, make osmanthus extract, can be used in food, cosmetics, can make cakes, candies, and can make wine. It is also an ornamental plant. Sweet-scented osmanthus is pungent and can be used as medicine. Sweet-scented osmanthus has the function of edible health care, and sweet-scented osmanthus tea has a refreshing effect. After being slightly scalded in boiling water, sweet-scented osmanthus is picked up and dried, crushed with sugar and sealed in a bottle to maintain its color and aroma and can be used as a food spice. Sweet-scented osmanthus, pure lotus root powder mixed with white sugar, it becomes sweet-scented osmanthus lotus root powder, delicious and appetizing. Take high-quality jujube, add sugar to boil, when the soup is about to run out, add sweet-scented osmanthus, that is, sweet-scented osmanthus jujube with invigorating spleen and appetizer. According to traditional Chinese medicine, sweet-scented osmanthus has a warm taste, fried soup, tea or wine, can remove phlegm and blood stasis, and has a certain curative effect on loss of appetite, phlegm, cough and asthma, intestinal wind and blood dysentery and abdominal pain with amenorrhea. Cassia twig, cinnamon seed and cinnamon root can all be used as medicine. Guizhi decoction, made of cassia twig, peony and ginger, jujube and licorice, specializes in treating exogenous wind pathogens, fever and headache. Cinnamon root tastes sweet and slightly astringent. Sweet-scented osmanthus tree propagation: grafting rootstocks can use privet, lobular privet, white wax and tassel and so on. When propagating in large numbers, lobular privet is often used in the north. Before sprouting in spring, cut the rootstock from 5 cm above the ground, cut the 1-to 2-year-old sturdy branches of sweet-scented osmanthus 10 to 12 cm long, and cut both sides of the base into a 45-degree slope. Cut longitudinally at about 1/3 on one side of the rootstock, 2 to 3 cm deep. Insert the scion into the incision, align the cambium, bind it tightly with a plastic bag, and bury it in the soil. Using lobular privet as rootstock has high survival rate and fast growth, but it is easy to form the phenomenon of "small feet". Potted sweet-scented osmanthus is often used by grafting, with tassel as rootstock. Grafting should be carried out in the growing season, select scions and rootstocks with similar branch thickness, cut into prismatic incisions in the appropriate parts of the scion, reaching to the xylem. Cut a cut consistent with the size of the scion on the rootstock, lean the two interfaces together, connect the forming layer closely, and fasten it with a plastic strip. After healing, cut off the rootstock on the interface and the scion below. Before cutting propagation sprouts in spring, select one-year-old developed branches and cut them into 5 to 10 cm long. Cut off the lower leaves, leave 2 to 3 leaves in the upper part, and insert them in the river sand or loess seedbed with a row spacing of 3 × 20 cm. Irrigation shade in time after insertion, keep the temperature from 20 ℃ to 25 ℃, relative humidity 85% to 90% can take root for 2 months. Striping propagation is divided into two types: low pressure and high pressure. Under low pressure, the low-branched or tufted mother plant of sweet-scented osmanthus should be selected. From spring to early summer, the branches of the lower 1-2-year-old flexible parts should be cut or girdled with a sharp knife to reach the xylem, pressed into grooves 3 to 5 cm deep and fixed with wood strips. In the high-pressure method, 1-2-year-old branches were selected from the mother tree in spring. after girdling, the wound was wrapped in a culture medium and fastened in a plastic bag. In the process of culture, the substrate was kept moist all the time, and the roots were cut off from the mother plant in autumn. Osmanthus fragrans seedlings: the common method of sowing and raising seedlings. A large number of sweet-scented osmanthus seedlings can be obtained by sowing and raising seedlings, which is suitable to be used as street trees. Sowing commonly used wide strip sowing, row spacing of 20 to 25 cm, width of 10 to 12 cm, 20 kg per mu of sowing, per mu of sweet-scented osmanthus seedlings 2.5 to 30,000. Before sowing, put the navel to one side, cover one or two centimeters of fine soil, cover with a thin layer of straw, and spray water until the soil is soaked to prevent soil consolidation and reduce water evaporation. When the seeds germinated and unearthed, uncover the grass in time and put the grass between the rows, which can not only keep the soil moist, but also prevent the growth of weeds. Osmanthus Osmanthus tree transplanting: 1. Transplanting time: the transplanting of osmanthus can be in spring or autumn, but the best transplanting is in spring. Transplanting in autumn should be carried out in the place where the temperature gradually turns cool and the water is abundant, and generally transplant in the south of central Guangxi after October. 2. Selection of transplanting seedlings: in August, Gui should choose seedlings with good growth, strong branches, no diseases and insect pests, new shoots and transplants. At the same time, August cassia seedlings should not be fertilized a month ago, and those seedlings that use plant hormones to promote growth had better not be used for transplanting. 3. Soil preparation: the specific way of soil preparation is determined according to the size of the seedlings that are transplanted in August, but no matter what kind of specific way of land preparation, it is best to completely reclaim and release base fertilizer first. If the seedling height of osmanthus is less than 1 meter, it is better to plant on the border, with a length of 20 meters and a width of 0.9 to 1.2 meters. Plant spacing 10 to 30 cm, row spacing 20 to 40 cm; if the seedling height is more than 1 meter, it is best to dig ridge planting, the size of the ridge depends on the seedling, open a good drainage and irrigation ditch. 4, seedling: eight laurel seedlings in cloudy or sunny morning or late, do not rise seedlings in rainy days, the best time not to rise seedlings more than two days, should be irrigated 3 to 5 days in advance, with a hoe, shovel to raise seedlings, the general seedling diameter of less than 2 cm can be bare root seedlings, leaving root length (main root) not less than 15 cm; more than 2 cm to take soil ball, the size of soil ball is 6 to 10 times of diameter class. Try to hurt the roots as little as possible, and do not pull out the seedlings. Long-distance transportation or sunny days should be timely dipped in yellow mud bare root seedlings, and wrapped with wet straw or film, and tightly tied into bundles. Apply straw rope to the seedlings with soil balls or bind them with food bags and ropes. If the earth ball is incomplete, it should be mended with wet yellow mud. The good August cinnamon should be placed in the place of back sun and leeward, and cover the root with a vulva net. 5. Loading and transportation: except for noon in sunny days and rainy days, the rest of the time can be loaded. The bare root seedlings of cinnamon in August can be dressed upright or horizontally, be careful not to trample on the trunk and roots when loading the car, and be careful not to break the terminal bud if the tree is less than 1 meter high. Those with dirt balls should be loaded and loaded, and the number of layers can be determined according to the size of the earth balls, generally no more than 5 layers, and be careful not to be overhigh or overweight. It is best to cover the August osmanthus seedlings with tarpaulins or shade nets, and do not water the seedlings. The transportation had better arrive at the destination within two days. 6. Treatment of seedlings before planting: after Gui Miao is transported to its destination in August, it should be unloaded immediately. Put the seedlings firmly in a place where the wind, sun, or shade is used. If planting in time, you can unload the seedlings at the planting point, pay attention to shading the roots of seedlings with shade nets or other items that can shade but not easily raise the temperature too high on a sunny day; prune the branches, leaves and roots of laurel, generally do not hit the top if the seedling height is less than 1 meter, depending on the situation, the remaining branches and leaves account for 1 to 1 pound of the total branches and leaves, and the big ones can stay more. For the root is mainly split root, long root and so on for pruning. Pruning can be done before planting or can be pruned while planting. 7. Planting: for the August cassia seedlings planted on the border, plant them according to the specifications; for the August cassia seedlings planted in the ridge, first put a small amount of loose soil at the bottom of the ridge, stand the seedling in the center of the ridge, the root neck of the seedling is 3 to 5 cm high, straighten the backfill soil to about 1x2 of the ridge, lift the seedling slightly, then to 2 to 3 cm of the ridge, compacted around and backfill the soil to the ridge. If the weather is dry when planting, you can use yellow mud and 1% calcium to pulp the root and then plant it, and you can also mix mud in the ridge. It should be watered in time after planting. Sweet-scented osmanthus tree disease: anthracnose is easy to occur in a high-temperature and humid environment. At the initial stage of the disease, there are nearly round purple-brown spots on the stems and leaves, and there are black spots on them. In the later stage of the disease, peach sticky substance overflowed from the small black spots, resulting in dead leaves. Starting from July and August, after spraying 500-600x solution of Dyson zinc once or twice, 50% Dysenamine 800-1000 fold solution was used to control it, and the litter and weeds in the garden were completely removed in winter. Apical spot disease often occurs at the tip or edge of the leaf. At the initial stage of the disease, small brown spots appeared on the leaves, which gradually expanded into round or irregular disease spots. In the later stage of the disease, there are many black dots on the disease spot, but there is no mucous overflow. In severe cases, multiple disease spots are connected to form large withered spots, and the leaves are curled and broken. At the beginning of the disease, 1 ∶ 2 ∶ Bordeaux solution was sprayed, and then 50% benzoate wettable powder 1000 to 1500 times was used for prevention and treatment. In the early stage of the onset of brown spot, chlorotic small yellow spots appeared on the leaves, which gradually expanded into nearly round spots, yellowish brown to grayish brown, with a yellow halo on the periphery. In the later stage of the disease, black mildew is produced on the disease spot. When the disease spots are connected, the leaves die and fall off. At the initial stage of the disease, spray 1 ∶ 1 ∶ 200 Bordeaux solution, and half a month later, spray 65% Dysen zinc wettable powder 800x liquid or 50% bacilli wettable powder 1000 times solution for prevention and treatment. Rot mainly occurs in the root and stem, and the injured part is waterlogged. After the disease spot expands gradually, the plant growth weakens and even dies. The rainy season in summer and autumn is serious. A small amount of sulfur powder was sprinkled around the plant in early spring and white in winter. The whitening agent was prepared with 25 jin of quicklime, 3 jin of salt, 0.5 jin of vegetable oil, 1 jin of sulfur powder and 100 jin of water. After the appearance of the disease spot, shave it clean and apply Fumei arsenic kerosene agent. Sweet-scented osmanthus tree insect pests: 1, Jiding insect 1, harm: larvae eat in the cortex of branches, oil dotted brown colloid, when the damage is serious, the bark burst, the main branch or the whole plant withered, adults bite on tender leaves, and in serious cases, a large number of fallen leaves. Where the management is poor, the weak trees suffer more seriously. 2. Control: scrape off the bark during the peak hatching period of the larvae (usually May) and apply 20 times of 80% dichlorvos emulsion; during the adult occurrence period (about June), spray the crown with 1000 times of 90% trichlorfon for 2 to 3 times. 2. Scale insects 1. Harmful conditions: the scale insects that endanger sweet-scented osmanthus include red wax, blowing cotton, bran and so on. Nymphs and adults pierce the branches and tissues with oral needles to absorb sap, causing the branches and leaves to wither and die. At the same time, secrete honeydew, induce soot disease, serious harm. 2. Control: spray 20% chrysanthemum EC or 2.5% deltamethrin EC 2500 times during the nymph incubation period; spray 1500 times EC when the shell is formed, which has good control effect because of its strong permeability. Third, diamondback moth 1, harmful shape: the main diamondback moths that harm sweet-scented osmanthus are yellow diamondback moth, green diamondback moth, green diamondback moth, flat diamondback moth and so on. Most of the larvae overwintered in the cocoon, and the young larvae ate leaves in clusters, which was the heaviest from July to September, and the adults had strong phototaxis. 2. Prevention and control: use black light to trap and kill adults from May to June; manually remove cocoons attached to branches and trunks; chemical control should be carried out in time in the stage of young larvae. 2000 times of cypermethrin or 1000 times of trichlorfon can be selected to spray and kill larvae. Fourth, coir moth 1, harm shape: the main species that harm sweet-scented osmanthus are big coir moth, tea coir moth and so on. The larvae can spit silk into cocoons, which are covered with all kinds of broken branches and leaves, showing various forms of bags. Most of the larvae are concentrated on the top of the crown to feed on the leaves, and in severe cases, the leaves can be eaten, resulting in serious damage to plant growth and even death. 2. Prevention and control: cut off insect branches and remove cysts in winter; chemical control should be carried out in time in the stage of young larvae. 1000 times liquid of 95% crystal trichlorfon or 1000 times solution of 50% fenitrothion can be used to spray and kill larvae. The reason why sweet-scented osmanthus trees do not blossom: poor seedling selection by ①. There is a kind of purple cinnamon that can not blossom until it grows into a big tree. If the purple cinnamon cuttings are mistakenly cut into seedlings, it is difficult to blossom. Osmanthus fragrans seedlings should be grafted with mature branches of improved varieties as scions, or obtained by high pressure at the base of flowering branches, which is not only of good quality, but also easy to blossom after survival. ② was not cultivated properly. Neutral sandy soil is the most suitable, which often rarely blossoms or does not blossom in alkaline loam. Root injury or freezing during transplanting will weaken the growth and can not blossom within 3 to 5 years. Osmanthus fragrans prefer light and avoid temperature, and may not blossom if they are short of light for a long time. Too wet and rotten roots or long-term high temperature drying will also affect flower bud differentiation. Caused by ③ disease. Osmanthus fragrans are afraid of chlorine and are not resistant to smoke and dust. If the smoke is large, the growth is poor, the leaves become smaller and fall off, and can not blossom. Sweet-scented osmanthus is also vulnerable to anthracnose, shell insects and other diseases and pests, not timely control, also affect flowering. In addition, mistakenly cutting spring shoots will affect the flowering of the same year. Too many branches of sweet-scented osmanthus in full bloom will weaken the growth and affect the later flowering. Click to get more sweet-scented osmanthus planting techniques
