Key points for conservation of transplanting sweet-scented osmanthus trees

Sweet-scented osmanthus tree is our more common greening tree species, because sweet-scented osmanthus is relatively unique, so the ornamental value of sweet-scented osmanthus tree is also high, loved by many people. In landscaping, the price of sweet-scented osmanthus trees is also relatively high. However, some flower friends will find that sweet-scented osmanthus trees need careful care to ensure their survival after transplanting.

Osmanthus fragrans

1. Wrap the tree trunk

In order to reduce the evaporation of water from the trunk and maintain the humidity of the trunk, wrap the trunk closely from the base of the trunk with a moist grass rope, then cover the rope with clay mud, and then spray it with water to moisturize it, or wrap a layer of plastic film on the outside of the rope. In the hot summer, the canopy of newly transplanted trees should also be sprayed with plant transpiration inhibitors and drenched regularly to reduce water evaporation.

2. Bracing and strengthening

Support tree trunks, set up sunshade nets, hanging curtains, located in the southeast coast, typhoon activities are frequent, must be supported after planting, and must be firm. Leaf transpiration is large in summer and autumn. in order to maintain ecological balance, shade net and hanging curtain must be set up in shade shed.

3. Irrigating rooting liquid

Osmanthus fragrans should be irrigated with rooting liquid in time during planting or after transplanting, which can quickly stimulate the growth of new roots, increase the number of capillary roots and absorbing roots, improve the ability of trees to absorb water and fertilizer, and then achieve the purpose of transplanting survival. But the rooting liquid should choose the regular brand rooting solution of regular manufacturers, and the big tree rooting solution produced by Zhengzhou Linyi Biotechnology Co., Ltd is recommended here. It can be used 3 times in a row with an interval of 7 Mel for 15 days.

4. Prevent retting from roots

Root rot and root retting of newly transplanted trees is a fatal killer of tree survival. Once retting root trees are difficult to survive, the prevention of root rot should be done well in advance. The specific measures are to control the amount of watering and prevent a large amount of stagnant water in the roots (water is watered for the first time). In the future, according to the appropriate amount of soil moisture, do not water too much), disinfect tree pits and backfill soil during transplanting (root rot kang can be used), avoid planting too deep, and choose high planting or container pseudo-planting for pseudo-planted trees.

5. Use big tree drip to supplement life elements

The transplanting of large sweet-scented osmanthus trees can use Lindu brand tree drip, which can not only supplement a large number of trace elements and water needed for tree growth, but also stimulate tree cell growth activity and stimulate tree rooting and sprouting, so as to improve the survival rate of tree transplanting.

6. Watering and fertilizing

Watering should follow the principle of no drying and no watering, and watering means thorough watering. Especially in summer, it is necessary to spray water on the ground and canopy, and if necessary, add potassium dihydrogen phosphate or 0.3% urea solution to fertilize outside the root. In order to restore the tree potential as soon as possible, topdressing should be applied in the autumn of the first year after transplanting, but in a small amount. Fertilize 2-3 times in early spring and autumn in the second year, and topdressing outside the root if necessary.

What are the technical points of transplanting Osmanthus fragrans?

Sweet-scented osmanthus is one of the more common plants. Today, I would like to share with you the technical points of transplanting big sweet-scented osmanthus trees.

Transplanting season and selection of Osmanthus fragrans

Transplanting season of Osmanthus fragrans: the transplanting time of Osmanthus fragrans is too early, the temperature is high, the transpiration is large, the root system is easy to be damaged, the ability to absorb water is weakened, often resulting in fallen leaves and even death. Because most of the sweet-scented osmanthus trees are transplanted from the south, the time is too late and there is no transition stage, can not adapt to the northern climate, easy to freeze to death. Even if the survival is a few backbone branches, the branches and leaves are sparse, which can not achieve the effect required by the project. After groping, the best time for sweet-scented osmanthus trees in Zhengzhou is mid-November. At this time, the temperature began to drop, the transpiration was small, the ground temperature was high, and the wound of the injured root system healed quickly. At the same time, the root can grow some capillaries, alleviate the lack of nutrient absorption capacity, and ensure the smooth winter of sweet-scented osmanthus trees.

Sweet-scented osmanthus tree selection: to choose a full tree, luxuriant branches and leaves, no diseases and insect pests, easy to dig, lift sweet-scented osmanthus tree.

Work preparation before transplanting Osmanthus fragrans

Digging tree pits: the newly planted tree pits should be dug about a week before transplanting. The diameter of the pre-dug tree pits is about 1 meter larger than the packing diameter of the transplanted trees (convenient for workers to operate in the pits), and the height and height of the transplanting packaging can be level. The excavated topsoil and the subsoil are placed separately, spread out to dry, and clean up the bricks, tiles and other impurities in the soil. According to the mixture ratio of 10 ∶ 1 (10 parts of soil), ferrous sulfate was mixed to increase the acidity of the soil, disinfect the soil and enhance the fertility at the same time.

Pruning: pruning of sweet-scented osmanthus is one of the keys to transplant survival. Because the sprouting ability of sweet-scented osmanthus is not strong, it is not advisable to truncate and cut branches. You can only prune the leaves of sweet-scented osmanthus, cut them with scissors, leave petioles, protect axillary buds, and retain 1/3 of the original leaves. This can not only reduce the evaporation of water, but also retain the beauty of the original crown.

Seedling emergence and Transportation of Osmanthus fragrans

Seedling: the transplanting of sweet-scented osmanthus is best in hard packaging. The large sweet-scented osmanthus trees to be transplanted should be watered once a week in advance so that their roots can absorb enough water. In this way, it is easy to dig into balls, and the soil balls will not spread out because the soil is too dry. The diameter of the soil ball should be 8 times of the crown diameter of the height of 1 meter above ground, and the height is 70% of the diameter of the soil ball. It is better to dig big under the condition. When excavating, the topsoil at the base of the trunk should be removed, and the diameter of the lower mouth is 1 × 3 of the diameter of the upper mouth, and the diameter of the earth ball is 5ml / 10cm larger than the diameter of the formwork (in order to tighten the soil ball with the formwork). While digging the earth ball, prepare the formwork, wire piercing (steel wire cover), iron wire, etc., in order to pack the earth ball in time after digging. The big roots that need to be cut off should be sawed off by hand saw instead of chopping with other tools. The cross section of the roots should be adjusted to paste with sulfur powder and ABT rooting agent according to the ratio of 3 ∶ 2. After digging the earth ball, buckle the formwork quickly, tighten it with thread, and the tree trunk is packed with grass rope and hoisted.

Transport: the big sweet-scented osmanthus is hoisted to the vehicle to be placed upright, the earth ball is tied to death with woven bags around the original soil (the old soil of the earth-digging ball), and the crown is tightly wrapped with plastic film to prevent movement and shaking in the process of transportation.

Planting and later Management of Osmanthus fragrans

Planting: before planting, it is necessary to transport the original soil brought back by the sweet-scented osmanthus tree to the pre-dug tree hole with 10mm backfill soil. Because the sweet-scented osmanthus tree is not resistant to flooding, the depth of the planted sweet-scented osmanthus is 10m / 15cm higher than the original ground. First of all, put the sweet-scented osmanthus tree in the direction of its original growth, and then put a plastic pipe in each of the four corners of the tree pit to increase the air permeability of the root after filling the soil. Then remove the formwork sequentially while backfilling to 1x3 of the height of the earth ball, fill the original soil close to the surroundings of the soil ball, and fill a solid layer to prevent the soil ball from breaking. All the tree pits are filled firmly, cofferdam, braced and watered for the first time.

Post-management: first, it is 3 to 4 days from the first watering and then watered again. Second, after all the water is dry, the remaining soil around the original tree pit is surrounded by the roots to form a mound with high middle height and low surroundings, so that the sweet-scented osmanthus tree will not be drowned because of stagnant water. Third, the spring water must be watered once next spring. Fourth, the leaves and branches were sprayed with the mixture of potassium dihydrogen phosphate and fungicides (carbendazim, etc.) at an average temperature of about 20 ℃. It not only carried out foliar topdressing for sweet-scented osmanthus trees, but also played a role in sterilization.

The main technical points of transplanting sweet-scented osmanthus trees are shared with you here. I hope this article will be helpful to you.

Culture methods and matters needing attention of Osmanthus fragrans

The common cultivated varieties of sweet-scented osmanthus are cinnamon, cinnamon, silver cinnamon and four seasons osmanthus. The flowering time of different varieties of sweet-scented osmanthus is different, and the color of the flowers is also different. The flowering period of cinnamon is from September to October, and the color is often golden yellow. The flowering period of cinnamon is from September to October, and the color is white or yellow-white. Cinnamon florescence in October, the color is mostly orange red or orange yellow. Four seasons cinnamon blossoms, every month there are a small number of flowers, the color is white.

Planting Environment of Osmanthus fragrans

1. Cutting: the cutting time is generally from June to July or from September to October, and sandy loam is suitable for cutting. The semi-mature branches of the same year are selected for cuttings, and the terminal branches are the best. After cutting, it should be shaded and watered in time, and the management of water and fertilizer should be strengthened. Generally, cuttings begin to heal 20 days after cuttage, and can take root in 30-40 days. Cold prevention measures should be taken in winter, and the seedlings can grow to about 30 centimeters in the following year.

2. Pressing: there are two kinds of pressing: high pressure (air pressing) and ground pressure, which can be carried out all the year round. The high pressure method is carried out in the first ten days of April, and the ground pressure method should be carried out in the first ten days of April or the rainy season. Striping should be cut or ring-peeled, and separated from the mother plant after 1 year. The depth of the ground pressure strip is about 4-5 cm, and the more curved the branches are, the better.

3. Grafting: the propagation time of grafting is from March to April. The rootstock uses lobular privet and big leaf privet. The grafting method is branch grafting, cutting grafting, splitting grafting and leaning grafting. Shading and moisturizing are required when grafting. Splicing and splicing require that the interface be as low as possible, usually cutting off the rootstock 3 centimeters above the ground. After binding, the soil is cultivated to the top of the scion, so that it is possible to take root from the part of the scion and improve the survival rate.

4. Sowing: sowing in winter or early spring, strip sowing, row spacing 15-20 cm, 30-40 seeds per meter long, 8-10 kg per mu, covered with humus or burning soil, about 1.5 cm thick, and covered with grass. Generally, it begins to germinate 40-50 days after sowing and lasts for 50-60 days, and the germination is very irregular. The peak period of seedling growth is from July to September, so attention should be paid to topdressing and drought resistance. One-year-old seedlings can come out of the nursery if they are more than 30 cm high.

5. Seedlings coming out of the nursery: after the striping seedlings and grafted seedlings take root, they can be afforested in winter or planted in the nursery to cultivate large seedlings. The height of cutting seedling is more than 30 cm, the sowing seedling is more than 25 cm, and the ground diameter is more than 0.4 cm, which can be afforestation out of nursery or transplanted to large seedling cultivation area. The root system should be kept intact as far as possible when the seedlings are raised, and should be planted in time after the seedlings are raised. If long-distance transportation is needed, attention should be paid to moisturizing.

Variety Classification of Osmanthus fragrans

1. Four seasons cassia varieties: four seasons cassia tufted shrubby, tree-shaped low, short and dense branches, round crown. The new leaves are deep red and the old mature leaves are green or yellowish green. The leaf is oval in shape, and the intersection angle between the main vein and the lateral vein of the leaf is very large, close to the vertical state.

In which month does sweet-scented osmanthus bloom

1. Cinnamon: the florescence is from September to October, and the color is golden yellow. Yingui: the florescence is from September to October, the color is white or yellowish white. Cinnamon: the florescence is October, the color is orange-red or orange-yellow. Four Seasons Cinnamon: there are a small number of flowers every month, the color is white. In addition, the flowering time of sweet-scented osmanthus varies slightly according to different planting areas. Shanghai, Anhui, Jiangsu and Jiangsu basically opened in October, the northeast in August, Beijing, Tianjin and Hebei in September, and Sichuan, Guangxi and Shaanxi in September.

2. Osmanthus fragrans will not blossom until they are old enough to bloom. Sweet-scented osmanthus has a long life, generally can live for several decades to hundreds of years, and some even live to a thousand years, so its flowering age is relatively late. The seedlings sown take about ten years to blossom, the cuttings take four years to blossom, the grafted cinnamon has 1/5 to blossom the following year, and the grafted cinnamon blossoms in the same year, but very few. Some of the transplanted sweet-scented osmanthus trees can blossom in the same year, while others have to adapt to one or two years before they bloom.

How much is the sweet-scented osmanthus sapling?

1. Variety: the variety of sweet-scented osmanthus seedlings determines the price of sweet-scented osmanthus seedlings. Sweet-scented osmanthus is divided into four major varieties: Golden osmanthus, silver cinnamon, cinnamon and four seasons of osmanthus. Of course, there are many small varieties in each large variety, but the prices of small varieties under large varieties are similar. The price of cinnamon is the highest, with red flowers.

2. Size: sweet-scented osmanthus saplings are also large and small, and the big ones are of course a little more expensive. if small seedlings are now in the industry, they are generally distinguished according to the height of the seedlings (in the past, according to the age of the trees). At present, the most commonly planted seedlings are sweet-scented osmanthus seedlings with a height of about one meter.

3. Origin: the origin of sweet-scented osmanthus seedlings has a great relationship with the price, because the regional relationship first leads to different costs of cultivating sweet-scented osmanthus seedlings in different places, resulting in a little deviation in price. and the cost of seedling distribution and transportation also has a lot to do with the region.

Quantity: the purchase quantity of sweet-scented osmanthus seedlings is also closely related to the price. As we all know, if anything is purchased wholesale, the price will be a little cheaper.

How to grow Osmanthus fragrans well

1, timely watering: sweet-scented osmanthus pot soil should grasp the principle of whether it is dry or irrigated, but spray fresh water to the leaves once a day. After the Qingming Festival, the sweet-scented osmanthus should be watered once in the open air, which should be watered in the morning and evening in summer and around noon in winter, so that the water temperature is close to the soil temperature, so as not to cause sudden cold and heat, and pay attention not to stagnant water.

2. Rational fertilization: sweet-scented osmanthus is mainly ornamental, and sufficient fertilizer should be provided. Nitrogen fertilizer can be applied twice during shoot sprouting, and phosphorus fertilizer is mainly applied before flower bud differentiation and flowering. The basin soil should be a little drier before fertilization, and it is appropriate to loosen the soil first so that the fertilizer can be absorbed, and water should be watered the next day.

3. Pour the basin and change the soil: the sweet-scented osmanthus should change the soil once every 2 ~ 3 years, cut off part of the old and withered roots, cover the bottom of the basin with a layer of river sand or vermiculite to facilitate ventilation and drainage, and place rotten cake fertilizer as the base fertilizer, the fill must be compacted. The ratio of soil to soil is not very strict, and it can usually be made of garden soil, barnyard manure and river sand.

4. Pruning and shaping: Osmanthus fragrans generally adopt the method of combination of climbing and pruning, which should be carried out after autumn. Plants with poor tree shape can cut off the whole top branch at 2 / 3 or 3 / 4, and plants with too dense branches should be thinned. After flowering, they should also cut off overgrown branches, withered branches, disease and insect branches, dense and thin branches.

5. Overwintering management: sweet-scented osmanthus overwintering room temperature should be kept at 0: 5 ℃ and relative humidity at 50: 80%. Winter cold indoor light should be good, especially before the early spring buds began to sprout, but also required sufficient sunshine, the following year Grain Rain arranged potted sweet-scented osmanthus to come out of the room. After leaving the room, first concentrate on the outdoor leeward to the sun, so that it gradually adapt to the external environment.

6. disease control: the common diseases of sweet-scented osmanthus are leaf spot, coal pollution, algae spot, root rot, iron deficiency and so on. Leaf spot, coal pollution and algal spot can be sprayed with 0.5 Bordeaux solution or 5% carbendazim 500-1000 times. Root rot should pay attention to keep the soil loose and permeable, do not accumulate water.

7. pest control: the common pests of sweet-scented osmanthus are leaf wasp, whitefly, mite, white scale, yellow moth and so on. Leaf wasps, whitefly and mites can be sprayed with 40% dimethoate 1500-3000 times liquid, and Changbai scale can be sprayed with 40% omethoate 1000 times solution or 40% fenitrothion 500 times solution in the first and second generation nymphs except manual brushing.

Pruning methods of sweet-scented osmanthus bonsai

1. The pruning of the viewing period refers to the pruning of the sweet-scented osmanthus trees after the bonsai is formed, in order to protect and maintain the beautiful shape of the osmanthus trees. This kind of pruning is long-term. A large number of them must be done well.

2. The trunk and main branch of sweet-scented osmanthus bonsai cultivated with tree stump have been determined after stereotyped and pruned. What needs further processing and pruning are the secondary branches and the finer tertiary branches. The basic points to be mastered in the processing and pruning of these branches are: a branch should have a certain degree of curvature, and each branch should be divided into length and length in order to be beautiful.

3. When pruning, the cluttered cross branches, overlapping branches, parallel branches and opposite branches should be adjusted, that is, one of them should be cut or thinned. For the branches left behind, they can grow stout because of the concentration of nutrients. When the cultured branch grows to a suitable thickness, it is pruned with strength to shorten it. Give birth to the second branch. When the second branch grows to a suitable thickness, it will be cut again. In the future, the second and fourth branches will be treated in the same way. Usually two twigs are left on each branch. The twigs are long and short. After years of pruning, the branches are short, stout, vigorous and powerful, and gradually form the required tree shape.

Seed sowing method of sweet-scented osmanthus

The main results are as follows: 1. From February to early April of the following year, the seeds can be sowed and raised only when the seeds are white. The strip sowing method is generally used, that is, to make horizontal or longitudinal grooves on the seedling bed, with a width of 12 cm and a depth of 3 cm, and sow a germinated seed every 6-8 cm in the ditch. When sowing, the navel of the seed should be placed on the side so as not to bend the radicle and young stem and affect the growth of the seedlings. In Guilin area, it is usually sown with wide strips, with a row spacing of 20 cm, a width of 10 cm and a width of 10 cm. Sowing 20 kg per mu can produce 25000 seedlings.

2. Cover the fine soil immediately after sowing, and the thickness of the soil should be no more than 2-3 times the transverse diameter of the seed; smooth the border surface after covering the soil to avoid stagnant water; cover with a thin layer of straw to prevent the cover grass from being blown away by the wind; then spray water fully with a fine-eye sprayer until the soil is soaked. Grass mulching and water spraying can keep the soil moist, avoid soil hardening, and promote early germination and emergence of seeds.

How can sweet-scented osmanthus blossom more?

1. Select the basin soil: sweet-scented osmanthus likes slightly acidic soil. Pot culture can choose 5 parts of mountain mud, 3 parts of humus soil, 2 parts of sandy soil or half of rotten leaf soil and sandy loam soil as culture soil. If the soil is too acidic, the growth is slow and the leaves are withered and yellow. If alkaline soil is used, it can lead to leaf withering and even death after 2-3 months.

2. timely watering: sweet-scented osmanthus watering should be mastered "two less and one more", that is, less watering before the occurrence of new shoots, less watering in rainy days, and more watering in dry weather in summer and autumn. Usually watering is appropriate to keep the water content of the basin soil about 50%. Drainage should be carried out in time on cloudy and rainy days to prevent stagnant water in the basin from rotting roots, otherwise it is easy to "drown".

3. Skillfully applying topdressing: sweet-scented osmanthus likes pig dung, and the flower proverb is "to get sweet-scented osmanthus, prepare more pig manure tanks". If the rotten and thin pig manure is applied once every 10 to 15 days from April to May, once every 10 to 10 days from June to July, and the last time at the beginning of August, the sweet-scented osmanthus will grow luxuriantly, bloom more and taste fragrant. There is no pig manure in the city, so rotten cake liquid can be used. If there is not enough fertilizer, there will be fewer branches, fewer flowers, and no fragrance.

4. Proper pruning: Osmanthus fragrans have developed root system and strong germination. Adult sweet-scented osmanthus trees shoot twice a year. Therefore, in order to make sweet-scented osmanthus blossom flourish, it is necessary to prune properly to maintain the physiological balance between reproductive growth and vegetative growth. In general, long branches, weak branches, disease and insect branches should be cut off to facilitate ventilation and light, nutrient concentration, to promote sweet-scented osmanthus to give birth to more and fuller flower buds, then bloom luxuriantly.
