Safe tree culture methods and matters needing attention: watering | fertilization | Light | temperature

Ping an Tree (Orchid Island Cinnamon) is not only a beautiful potted foliage plant, but also a very beautiful landscape tree. It is more popular in the market and has broad prospects. So how are Ping an trees raised? Is there any good method in breeding? What matters do we need to pay attention to in breeding? Please read on with me with questions.

The culture method of Ping an tree (basic knowledge):

The best propagation time is from April to May in the first half of the year, from September to October in the second half of the year, and the best time is when the temperature is from 22 ℃ to 28 ℃.

The best growth soil: ping an tree pot or bag culture Ping an tree (Lanyu cinnamon), it is appropriate to use loose and permeable, smooth drainage, rich in organic matter fertile acid culture soil or rotten leaf soil.

Growth humidity requirements: ping an tree likes a humid environment and is not resistant to drought, its basin soil should be kept relatively moist, leaves should be sprayed with water in dry weather, leaves should be sprayed once a day in summer, and indoor relative air humidity should be kept above 60%.

The optimum growth temperature of Ping an tree is from 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, or 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.

The best growth light: the safe tree not only likes the sun but also is very shady, but it can not be exposed to the sun, especially when it is placed in the sun in summer, it is appropriate to cover about 50% of its area, otherwise the sun may burn the leaves. It can be exposed to the sun directly in winter without the need for shelter.

Points for attention in culturing Ping an trees:

Application of fertilizer: in addition to the fertile cultivation soil, Ping an tree can 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.

Watering points: Anshu likes a humid environment and is not resistant to drought, and its basin soil should be kept relatively moist. The number of times of watering varies according to the season, and it can be watered when the topsoil is a little dry. Spray water on the leaves in dry weather, and spray the leaves once a day in summer. Safe trees should be watered after autumn, and should be sprayed more and less in winter. If there is stagnant water in the basin soil, it is easy to lead to plant yellowing.

Key points of reproduction: safe trees (Lanyu cinnamon) are raised by sowing method. Mature purple-black fruits can be used to sow seeds in South China from September to October. After the crack of the seed is exposed, sow in the field or sow in the bag. For seeds that have not been germinated by sand storage, soak the seeds with 0.3% formalin solution for 30 minutes before sowing, pour out the excess liquid, seal it for 2 hours, rinse with clean water to remove the solution attached to the seed coat, and then soak the seeds with water for 24 hours. The germination rate can be increased. If the seeds are not disinfected, the seeds can be soaked in warm water of about 40 ℃, and the germination rate can also be increased. It is usually ditched and sown on demand, with row spacing of 20 to 25 meters, plant spacing of 5 to 7 meters, soil thickness of 1.5 to 2 meters, moisturizing with straw, and germination after 20 to 30 days. Keep the seedbed moist, uncover the grass for 2 to 3 times after the seeds are unearthed for 1 / 3, and then set up a shed to shade. When the seedlings grow 3 to 4 true leaves, liquid fertilizer can be applied once a month and stopped after autumn, so as to survive the winter at a greenhouse temperature of not less than 5 ℃.

Pruning essentials: safe tree spring pruning, when the temperature is 20 ℃, part of the branches will be cut short, in order to increase the number of branches, but should pay attention to pruning, the cut to the internode bud hole, the distance should be larger, otherwise it will lose water and cause the branches to wither. And the cut must be smooth, there must be no tear-like safety tree in the process of vegetative growth, timely pick the heart, promote more branches, can avoid plant shape imbalance, practice has proved that when maintaining the safety tree in the north, the effect of timely heart-picking is better than pruning.

Pot soil replacement: during the growing season of potted Ping an trees, it is best to loosen the soil once a month to keep their roots in a good state of permeability. Small Ping an trees can change pots once a year, while large ones can change pots once every 2 to 3 years. When changing pots, part of the necrotic roots can be cut off to ensure the normal growth of potted plants.

Pest control:

Leaf curl: it often occurs in summer and autumn, it curls several new leaves into nests, in which larvae lurk to feed on leaves, which can be sprayed with 800 times of 90% trichlorfon crystals or 100 times of 40% dimethoate EC.

Aphids: the young leaves and new buds of Lanyu cinnamon 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.

The experience of cultivating Ping an trees:

Culture Ping an tree usually should pay attention to moderate light, when placed in the sun in summer, it is appropriate to cover about 50% of its area, otherwise the sun may burn the leaves. The temperature should be kept between 20 ℃ and 30 ℃.

Fertilizing every other month except winter, winter fertilization may hurt the roots. The safe tree will produce anthracnose, which will make the leaf surface, leaf tip and leaf edge brown. When it is found, in addition to removing the diseased leaves in time, it is also necessary to apply more phosphorus and potassium fertilizer to improve the plant's ability to resist diseases and insect pests. Avoid stagnant water in the basin in Meiyu weather, otherwise it may damage the roots.
