Culture methods and matters needing attention of indoor potted safe trees

Ping an tree is the elegant name of Orchid Island cinnamon. It can emit the fragrance of correcting peculiar smell and purifying the air. People in the flower growing industry and business have given it an auspicious name "Ping an Tree". The safe tree means auspiciousness, symbolizes peace and happiness, and has a happy life. The following editor will introduce in detail the breeding methods and matters needing attention of the safe tree.

The Culture method of Ping an Tree

1. Temperature. The suitable temperature for the growth of Ping an tree is 20 ℃ to 30 ℃. Young trees are not tolerant to low temperature. If frost lasts for more than 5 days, the plants maintained or cultivated in the open field can easily lead to bark cracking, branches and leaves withering, and even the whole plant being frozen to death. Whether it is a small number of plants in family pot or large-scale production and management cultivation, the greenhouse temperature should be maintained at no less than 5 ℃ in winter in order to keep the leaves green and beautiful all the time. Larger plants can endure a low temperature of about 0 ℃ for a short time when there is no cold wind in the greenhouse. Potted plants in the Yangtze River basin should be moved into the shed before Frosts Descent's arrival and leave the room after the Qingming Festival the following year. Pay attention to prevent the cold damage caused by late frost or late spring cold. At the height of summer, when the temperature is more than 32 ℃, it is necessary to build a shed to shade and spray water on the leaf surface in order to humidify and cool down, so that it can maintain exuberant growth.

2. Light. Ping an tree needs better light, but it is more shady. Its light demand varies with age, young trees are shade-tolerant, 3-5-year-old plants, under shade conditions, plant height grows fast, 6-10-year-old plants require sufficient light. After entering the summer, the potted plant can be transferred in the shade or under the sunshade of 40% to 50%, then the growth is ideal. If the light is too strong, it is easy to cause the leaves to turn yellow and lose their mind, and reduce their due ornamental value, especially the potted plants that have been displayed indoors for a long time, and when they are moved outdoors for restorative maintenance in summer, care must be taken. It should be maintained in an environment of 40% to 50% shade first, which must not be too urgent, otherwise it is very easy to cause leaf burns. In addition, when you encounter the sunny weather after a long rain in late spring and early summer, you should also do a good job of shading in time, otherwise it will also cause leaf burns, and it will be difficult to restore the verdant spirit of its leaves in a short time.

3. Moisture. A safe tree requires a humid environment. For this reason, potted plants should always keep the potted soil moist, but there should be no stagnant water, and the environmental relative humidity should be kept above 80%. In the period of high temperature in summer or relatively dry air in autumn, including when it is kept indoors in winter, we should often spray water on the leaf surface and the surrounding environment to create a relatively humid local space environment to promote its robust growth. Watering should be controlled after entering autumn, and more spraying and less watering should be done in winter. If there is stagnant water in the basin soil, it is easy to lead to plant yellowing, lower leaves yellowing and falling off, and in serious cases, the rotten roots of the plant will die, which should be paid special attention to in the rainy season.

4. Soil. Pot or bag culture of safe trees, it is appropriate to use loose and breathable, unobstructed drainage, rich in organic matter fertile acid culture soil or rotten leaf soil. The hardening of basin soil or pH value higher than 7.5 will also cause yellowing of plant leaves, serious poor growth and decrease of sprouting ability, and affect bud regeneration, and even shorten its cultivation life. For this reason, small plants should change pots once a year, large plants can change soil once every two years, and loosen the soil once a month during the growing season, especially after heavy rain, flowerpots should be checked in time, water should be poured out as soon as possible, and loose soil should be replaced as soon as possible. Potted plants, the annual time to turn the pot to change soil, it is best to arrange after the spring to sprout before it is more appropriate.

5. Fertilizer. Ping an tree has plump plants, large leaves and prosperous growth, so it needs a large amount of fertilizer. Potted safe trees not only require fertile soil, but also apply thin cake fertilizer or alum once a month from mid-spring to early autumn. After entering autumn, phosphate and potassium fertilizer should be applied twice continuously, such as 0.3% potassium dihydrogen phosphate solution, so as to increase the cold resistance of the plant, promote the young shoots to Lignification as early as possible, so that they can survive the winter safely. All forms of topdressing should be stopped in winter to prevent fertilizer from injuring the roots and causing the leaves to yellowing or scorching off, otherwise it is difficult to restore the original appearance of the plant.

6. Disease control

① anthracnose: mainly harms seedling stage and adult leaves. Leaf infection, mostly occurs in the leaf surface, leaf tip, leaf edge, brown, irregular shape, in the later stage often expand or merge into gray-brown spots, the edge of brown, wavy, there are many small black spots on the spot, that is, its conidial disk. Conidia are transmitted by wind and rain, and spore germination invades leaves or seedlings when humidity is high, which is easy to occur in continuous rain, lack of sunlight, soil viscosity or moisture retention in the shed, and is the most popular from February to April. Prevention and control methods: find a small number of diseased leaves, remove and destroy them in time; increase the application of phosphorus and potassium fertilizer in the growing season to improve plant resistance; at the initial stage of the disease, use 25% carbolin wettable powder 500 times liquid, or 60% carbolin wettable powder 700 times liquid, or 75% methyl topiramate wettable powder 600 times liquid, spray alternately, every 10 to 15 days, 3 to 4 times in a row.

② brown spot occurred on the new leaves of the plant from April to May, the oval yellow-brown spot began to appear on the leaf surface, and then expanded continuously, and there were more small black spots on the front of the leaf, and the back of the spot was purple, so that the whole leaf yellowed and withered, resulting in a large number of deciduous leaves. Prevention and treatment methods: 1% Bordeaux solution can be used for prevention; a small number of diseased leaves should be removed and burned in time; at the initial stage of the disease, 50% carbendazim wettable powder or 50% carbendazim wettable powder 1000 times, or 50% fungicidal aqua regia 1000 times, alternately sprayed every 10 days, 3 to 4 times in a row.

③ brown root disease: the leaves of diseased trees gradually turn yellow and droop, turn brown and dry in severe cases, the stems lose water and dry up, the roots turn brown and rot, and the diseased plants die in a short time. Diseased roots, diseased soil and residual plants left behind are the initial infection sources of the disease, which are transmitted by wind, rain or contact, usually occurring in a single plant. Control methods: seriously diseased plants and plants withered due to disease should be uprooted and burned, and disinfected with 50% carbendazim wettable powder 600 times. At the initial stage of the disease, 50% carbendazim methyl should be sprayed. Sulfur suspension 800 times liquid, or 50% Gen Fuling wettable powder 800 times liquid, carry on the prevention and control.

7. Pest control

① leaf curl: it often occurs in summer and autumn. It curls several new leaves into nests, in which the larvae lurk to feed on the leaves. They can be sprayed with 90% trichlorfon crystal 800x solution or 40% dimethoate EC 100x solution.

② aphids: the young leaves and new buds of Ping an tree are prone to aphid piercing harm, resulting in greasy leaves, and then induced coal fouling disease, affecting plant growth and display. Control method: after spreading plant ash on the plant, rinse it with clean water; spray neem leaf juice, which can effectively kill insects; spray imidacloprid wettable powder 2000 times.

Matters needing attention in Ping an Tree Culture

1. A small number of diseased leaves should be removed and burned in time to avoid yellowing and withering of the whole leaves, resulting in a large number of fallen leaves.

2. In Meiyu weather, it is necessary to prevent stagnant water in the basin. If there is stagnant water in the basin soil, it will easily lead to plant yellowing, lower leaves will fall off after yellowing, and in serious cases, it will cause damage to the rhizome and even death of rotten roots.

The reason why the leaves of Ping an tree turn yellow

The main reasons for the yellowing or shedding of leaves in Ping an trees are as follows:

The main results are as follows: 1. Due to accidents or special circumstances, the root system of the plant is seriously damaged, and the leaves turn yellow.

2. The yellow and fallen leaves of Ping an tree were caused by freezing injury when the indoor temperature was below 5 ℃.

3. Too much watering leads to rotten roots at the bottom and causes the plants to yellowing and falling leaves.

4. The water quality is too alkaline, which leads to the slow yellowing of leaves, which is more common in the north, especially in other places.

5. improper fertilization, excessive fertilization and excessive concentration, resulting in water loss, atrophy and necrosis of nutritious fibrous roots.

6. after exposure to the hot sun for a long time, the leaves withered and yellowed.

The solution to the yellowing of the leaves of the Ping an tree is: when it is found that the leaves of the tree are yellowing, you should immediately check whether the roots of the tree are growing normally, and if you find that its roots are rotting, immediately remove the decayed parts, yellowing or dead leaves, cut off and replant them.

Culture methods and matters needing attention of Ping an Tree

The safe tree is fertilized.

Ping an tree has a high demand for fertilizer. From spring to autumn, Ping an tree has to apply thin cake fertilizer once a month. After entering autumn, it needs to apply phosphorus and potassium fertilizer twice in a row, which can increase the cold resistance of the plant and promote the Lignification of new shoots in advance. So that it can survive the winter safely.

After entering the winter, we should stop all right and wrong, and prevent fertilizer from harming the plant's roots, causing the leaves to turn yellow or wither and fall.

How to water the safe tree

We all know that Ping an trees like to be applied to your growing environment, are not resistant to drought, and the basin soil should maintain a certain degree of humidity. The number of times of watering varies according to the season, and on the surface, if the topsoil is a little dry, it needs watering.

You need to spray water on the leaves in dry weather and keep watering them once a day in summer. Safe trees should control the amount of water after autumn, and spray more water and less water in winter. If there is stagnant water in the basin soil, it will cause the plant to yellowing.

Key points of propagation of Ping an tree

The propagation of Ping an tree is often carried out by sowing and sowing, and it is usually planted mainly by trenching and sowing in the south from September to October. When the seedlings of the plant grow 3-4 true leaves, liquid fertilizer should be applied once a month, stop fertilization after autumn, do a good job of cold prevention, and overwinter at an indoor temperature of not less than 5 ℃.

Essentials of safe Tree pruning

The safe tree is pruned in spring. When the temperature is 20 ℃, part of the branches will be trimmed short to increase the number of branches. The cut should be smooth and pick the heart in time to promote multiple branches and buds so as to avoid the imbalance of plant growth. Practice has proved that the effect of timely heart-picking of Ping an trees cultivated in the north is much better than that of pruning.

Safe tree pot soil replacement

Potted safe trees should loosen the soil once a month in order to maintain the normal development of their roots and make their roots in a good state of permeability. Small trees can change pots once a year, and large trees can change pots every 2-3 years. In the process of changing pots, all the necrotic roots should be cut off to ensure the normal growth and development of the plant.

The cultivation methods and points for attention of Ping an tree teach you how to raise Ping an tree.

Ping an tree, formerly known as Lanyu cinnamon, was originally produced in Lanyu Island. It is a kind of bright green and auspicious cinnamon, peace tree and peace wood. In recent years, began to enter the family, will be loved by flower lovers. So, what are the breeding methods and matters needing attention of Ping an tree? The editor will introduce you today and teach you how to raise a safe tree.

Culture methods and matters needing attention of Ping an Tree

1. With moderate light, plant culture needs good light to carry out photosynthesis in order to promote its effective growth. As a light-loving plant, Ping an tree has a natural demand for light, but at the same time it is also afraid of strong light exposure, so it should provide effective shading protection for tree plants in the hot summer sun, and potted plants can also be placed in a position with weak indoor sun. it can still grow well, because Ping an tree is relatively able to tolerate shade.

2. At the right temperature, Ping an tree likes warm heat and is not resistant to cold, so it is most suitable to grow at a temperature of 20 to 30 degrees. It is best to move into the house in winter so that the growth environment is not less than 5 degrees. Summer high temperature above 30 degrees should also do some protection, can spray water on its leaves to lower the temperature.

3. Watering correctly, during the growing period of spring and summer, the soil of Ping an tree should always be kept moist, and the leaves and culture environment should be sprayed frequently to maintain good air humidity. In addition, when watering Ping an trees, some vinegar can be added to improve the acidity of the soil, especially in view of the relative lack of acid in the northern soil, vinegar can be added to the watering to adjust the acidity of the soil.

4. Soil and flowerpot, Ping an tree is suitable to grow in loose, breathable, rich acid decaying leaf soil or culture soil. It is necessary to loosen the soil every other month and change the pot soil every two years. The bottom of the flowerpot should be breathable, and it should not be too small, because Ping an tree grows faster, and too small will hinder its growth.

5. Fertilization, the fertilization of Ping an tree varies according to different growth periods. A pot plant that has just been planted can be used once a month after teething, but in the process of fertilizing the Ping an tree, we should pay attention to the sparse and thin application, and do not release too much oysters, otherwise it is easy to cause the roots of farmed plants to be burned. resulting in withered and yellow leaves until death. In addition, some potassium dihydrogen phosphate solution can be applied before winter to enhance the cold resistance of the plant.

6. Pest prevention, aphids are easy to grow on the young leaves and new buds of Ping an tree. After spreading plant ash, rinse with clean water; spray neem leaf juice, which can effectively kill insects; spray imidacloprid wettable powder 2000 times.
