How to plant cinnamon trees: Key points of cinnamon tree cultivation techniques.

How to plant camphor treesA comprehensive introduction to the planting and cultivation techniques of camphor trees in the field of green plants and flowers, next let's learn about it together.There are two methods of propagation for camphor trees: seeding and cutting. They are adaptable to altitudes below 1800 meters, with an absolute minimum temperature of -0.00°C. Camphor trees prefer sunlight but can tolerate shade; they thrive in warm and humid climates but are not very cold-resistant. They are not strict about soil requirements, with the best being fertile and permeable sandy soil. They can tolerate waterlogging but not drought, barrenness, or saline-alkali soil. They have a developed main root, deep root system, and can resist wind. They have strong germination and pruning tolerance. The growth rate is moderate, with a large tree shape like an umbrella that can provide shade and coolness. They have a long lifespan, growing into towering ancient trees of hundreds or even thousands of years, with strong abilities to smoke dust, conserve water sources, prevent soil erosion and sand, and beautify the environment! Additionally, they have resistance to ocean winds, tolerance to smoke and toxic gases, and can absorb various toxic gases, making them well-adapted to urban environments.In order to ensure a high survival rate during planting, attention should be paid to the following issues and corresponding technical measures should be taken during the planting process.I. Planting and Cultivation1. Planting TimeUsually from mid-March to mid-April, before the spring buds start to germinate. Supplementary planting can be done during the plum rain season. September is suitable for autumn planting. In areas with few frosts or more rainfall in winter, winter planting is also possible. Planting should be timely, meaning that the pruned camphor seedlings should be planted immediately. If the transportation distance is far, the rootstock should be wrapped with wet grass and plastic film to keep it moist. The best time for planting is before 11 a.m. or after 4 p.m., and in winter, it is enough to avoid the coldest days.2. PlantingThe planting hole should be dug according to the general technical procedures, with the depth, length, and width reaching 50-60 centimeters. The bottom of the hole should be fertilized and layered with fine soil, and the planting soil should be loose and fertile. Remove the wrapping material from the camphor seedlings, and the planting depth should be level with the ground and the root collar of the seedling. When planting, the protective soil should be tightly connected with the hole soil, and loose or unconsolidated backfill will cause voids. Insert the seedling vertically in the planting hole, tamp the soil after filling, and continue filling until the top of the hole. Finally, make a water-retaining barrier around the seedling.3. WateringAfter planting the camphor seedlings, water them immediately. For seedlings with soil balls, stir the soil around the hole with an iron rod or wooden rod while watering to ensure that the soil around the hole is filled. When watering, be careful not to damage the soil barrier, and fill the barrier with water to let it slowly seep into the planting hole. To further improve the survival rate, growth regulators can be added to the water to stimulate new root growth. NAA (naphthalene acetic acid) is commonly used as a growth regulator, dissolved in a small amount of alcohol first, then mixed with water to make a 200PPm solution for the first watering. Whether planting on a cloudy or sunny day, water thoroughly once. In dry and sunny weather, water every 7 days. Continuous watering for 3-4 times is sufficient.4. Special Technical TreatmentDuring the transplanting process, to maintain the humidity of the trunk and reduce the transpiration of water from the bark, wrap the trunk with wet grass rope until the top of the main stem, and if the branches are large, wrap them as well. Then, cover the grass rope-wrapped trunk thickly with clay slurry. Afterwards, frequently spray water on the trunk with a sprayer to keep it moist. After digging up the large camphor, prune the broken, damaged, and withered roots and then soak the roots in clay slurry; if the slurry is mixed with 0.03% NAA, it can promote the growth of new roots after transplanting the large camphor.5. Management and MaintenanceSince camphor trees are planted in an unsuitable off-season, it is even more important to strengthen maintenance management after planting. Normally, pay attention to watering, following the principle of "do not water when not dry, and water thoroughly when watering"; also frequently spray clean water on the ground and leaves of the camphor trees to increase air humidity and reduce plant transpiration.II. Transplanting Methods1. Root Pruning to Promote RootingFor seedlings with a trunk diameter of less than 10 centimeters, only need to dig soil balls according to the conventional requirements for transplanting. Usually, the diameter of the soil ball is about 5-6 times the diameter of the main stem. For large tree seedlings with a diameter of 10 centimeters or more, root pruning and root promotion treatments should be performed first. The specific method is: dig a slot on both sides of the main stem, 2-2.5 times the diameter of the tree trunk away from the trunk, and saw or cut off the thick lateral roots with a saw or sharp axe, making the cut surface smooth. Smaller lateral roots can be cut with pruning shears, then covered with fine soil to allow fine roots to grow near the cut ends in the same year, and the operation is repeated on the uncut sides in the second year, with the seedlings lifted in the spring of the third year.2. Trunk Cutting and Branch ReductionFor smaller seedlings, no cutting is needed for 1-2-year-old seedlings, while 3-6-year-old seedlings should have 1/3 of their branches cut, usually cutting off the lateral branches in the lower 1/3 of the main stem and the upper 2/3 in layers. Larger seedlings should have all branches cut. Usually, the height of the main stem of street trees is controlled at 3-3.5 meters, with thick lateral branches retained at 0.3-0.5 meters. After cutting, seal the cut ends with wax or wrap them with plastic film to prevent water loss.3. Ball Lifting and WrappingThe best time for lifting seedlings and transplanting is March, with the soil ball being 5-6 times the diameter of the chest (30-40 centimeters for small seedlings), wrapped with straw rope to ensure the ball does not disperse.4. TransplantingThe diameter of the planting hole should be 1/3 larger than the camphor soil ball, and the depth should be such that the soil ball is in the ground and the root collar is level with the ground. After planting the tree, fill the gaps with fine soil and tamp it down with a thick stick. When there are 10-20 centimeters left, water to absorb the moisture, then fill the remaining soil until the base of the tree trunk is dome-shaped.III. Pest ControlCamphor trees have a majestic posture, colorful spring leaves, and dense foliage, making them the most common landscaping trees in the south, widely used as shade trees, street trees, and for creating landscape and protective forests. Here is a brief introduction to the prevention and control of their diseases and pests:1. Powdery Mildew:This disease often occurs in nursery seedlings. It is most likely to occur under conditions of high temperature, humidity, dense seedlings, and poor ventilation. Gray-brown spots appear on the back of the leaves near the main veins, which then spread to the entire back of the leaf and form a layer of white powder, severe cases can also have white powder on the tender branches and trunk.(1) The nursery should pay attention to environmental hygiene and properly thin seedlings, or immediately remove or burn diseased plants when a few are found.(2) When it occurs, use a 0.3-0.5 degree Bordeaux mixture solution to spray every 10 days, for three or four consecutive times.2. Black Spot Disease:This disease commonly occurs when seedlings have 1-4 leaves after germination. The tip of the seedling turns black and brown and dies. Disinfect seeds, soil, and covering materials when sowing. When the disease occurs, first remove and burn the diseased seedlings, then spray 0.5% potassium permanganate or formalin two or three times to prevent the spread.3. Camphor Leaf Sawfly:This pest has multiple generations a year and a long period of harm. One-year-old seedlings can be severely affected and die, and the top of the tree canopy is often eaten by the larvae after afforestation, which can affect tree growth.You can use 0.5 kilograms of rhododendron or tripterygium powder mixed with 75-100 kilograms of clean water to make a solution for spraying the seedlings, or use 90% diazepam or 50% malathion emulsion at a concentration of 2000 times for spraying.4. Camphor Twig Roller:This pest has several generations a year, with larvae boring into branches, affecting the height growth of camphor trees, causing the trunk to bend.(1) After the new shoots of camphor trees emerge in March, spray 90% diazepam, 50% sodium dichloride emulsion, or 50% malathion emulsion at a concentration of 10,000 times when the first generation of larvae hatch, every 5 days for two or three consecutive times, which can kill the larvae. If the larvae have bored into the new shoots, you can also spray 40% dimethoate emulsion at a concentration of 200-300 times.(2) For nurseries or small-scale forests, collect and burn dead branches and leaves in winter to destroy overwintering pupae.5. Camphor Fruit Moth:This pest usually affects seedlings and young trees under 20 years old. There are two generations a year. The first generation of larvae occur from late May to mid-July, and the second generation from August to September. The larvae gather on new shoots to eat leaf buds, wrapping the residual leaves into balls, wrapping the top buds, causing the new shoots to wither and even the whole plant to die.(1) When the larvae start to move and have not yet formed net nests, spray with 90% diazepam at a concentration of 4000-50000 times, which can kill them.(2) If the larvae have formed net nests, it is best to cut and burn them.6. Camphor Longicorn:(1) During the egg-laying period (May to early June), use a wire brush to scrape the egg-laying scars to kill the eggs or newly hatched larvae.(2)剪除受害枝条，然后从排泄孔注入敌敌畏等药剂，将其中幼虫杀死。The above is the specific content of [Green Plant Enthusiast Website] on how to plant camphor trees and the cultivation techniques of camphor trees, and copying is prohibited without the permission of Green Plant Enthusiast Website!
