Black Pine Bonsai Making and Conservation

Black pine is an evergreen tree of Pinus, native to Japan and the coastal areas of southern Korea. It is suitable for growing in warm and humic marine climate areas. It is not only an excellent plant for potted plants, but also an excellent seedling for landscaping. Let's take a look at the production and maintenance of black pine bonsai.

Application of Black Pine Bonsai

Black pine bonsai has a strong ability to adapt to the environment, courtyard and balcony can be cultivated. Its branches spread horizontally, the crown is like an umbrella cover, the needles are dark green, the four seasons are evergreen, and the tree posture is quaint and elegant, which can be appreciated all the year round. During the growth period, it should be placed outside where there is plenty of sunshine and air flow, and should not be placed indoors for a long time. The black pine pile scene, which has been cultivated for many years, is always vigorous and Qiu qu, with intertwined roots, showing the strange posture and indomitable vitality of the dragon's style, which is a good product for the family to cultivate and watch.

The habit of black pine bonsai

Black pine multi-purpose seed seedling propagation, the germination rate is high, up to 85%, the seedling growth is exuberant. The seeds were harvested in the middle and late October, exposed to sun and threshed, cleaned by the wind and stored in bags for the winter. Spring sowing should be early, and the slightly acidic soil with loose soil and good drainage should be used in the nursery, combined with soil preparation, sufficient base fertilizer, and soil disinfection. Soak the seeds in 0.5% potassium permanganate solution for 2 hours before sowing, then soak in 60 ℃ warm water for one day and night (natural cooling). Remove and spread out in a warm place, sprinkle with water once or twice a day, and sow seeds after a week. It began to sprout and unearthed in the middle and last ten days of April, and can come out in 10 days, and the seedlings of that year can be as high as 10-15 cm. Potted plants can be planted with 2-or 3-year-old stout saplings and then processed and modeled.

Production of black pine bonsai

1. When mining, the mining face should be expanded, and attention should be paid to carrying as much soil as possible. Because black pine grows in the sand and gravel soil on the hillside, the soil is less, and the weather is dry in winter, and the soil contains less water and poor stickiness, so it is necessary to protect the root soil as much as possible when mining. Because the root soil is rich in root mold, it is a symbiotic fungus of Pinus koraiensis, which is very conducive to root growth. After excavation, plastic bags should be used to make simple bandage in time to prevent soil loss during handling and facilitate transplanting.

2. When digging, we should pay attention to protect the root system of black pine, start digging a little farther away from the pine tree, first dig out the surrounding soil, keep the main root as much as possible, cut off the root smoothly, cut off the rotten root, and avoid damaging the root system as far as possible. Especially the lateral root and fibrous root of black pine in sand and gravel, the root system is weak, stay as long as possible, and should be protected especially when digging.

3. The black pine dug back should be buried in time, and the faster the better, the longer the time will cause the root to lose water and dry up, which will affect the survival. In order to prevent the roots from being buried too deep, we can take high planting and shallow planting, and then add soil to cover it. Those who have no conditions to cultivate in the field should be pots in time.

4. The upper basin of black pine is very important. Before cultivation, gravel and tiles of the basin bottom cushion are first used to facilitate ventilation and drainage, and then fill the surrounding area with soil. The gap in the soil is too large, it is easy to cause frozen roots, the basin is covered with grass curtain to prevent freezing. The original soil on the mountain is the best for the soil, and the mixture of coarse yellow sand, coal ash and yellow mud can also be used, and the proportion is 0.5-0.25-0.25. It should be fortified in time after potting, too many branches and leaves will affect the insufficient water supply of roots and consume a lot of water and nutrition.

Maintenance of black pine bonsai

1. Environment: black pine is cold-resistant and drought-resistant, and can be placed on the courtyard slope and balcony all the year round, where the light is sufficient and the air flows. However, small bonsai should not be exposed to strong light at the height of summer. Winter can be overwintered in the open field, it is best to bury the basin in the sunny leeward place. If you spend the winter indoors, the room temperature should not be too high, Ching Ming Festival can move to the outside.

2, watering: black pine likes to dry and avoid stagnant water, watering should not be excessive, only when it is dry, it will be watered thoroughly. Proper water control during the growing period can make the branches thick and short, the needles short, and increase the ornamental value. When it is hot in summer, foliar water can be sprayed frequently, which is beneficial to growth.

3. Fertilization: black pine is resistant to barren, the soil is short of fertilizer, can also grow normally, and promote short stem, dense branches and short leaves. However, the proper application of thin and rotten cake fertilizer and water during the growing period is beneficial to robust growth and increase the ability of resistance to diseases and insect pests.

4. Pruning: in order to maintain its graceful and quaint tree shape, the bonsai of black pine should be pruned properly. During the growing period, the main pruning is to pick buds, 3 to 4 evenly every year. When the new buds elongate but have not yet produced needles, you can remove about 1 / 2 of each top bud. If you do not need bonsai to grow branches, you can pick all the terminal buds. The branches that affect the appearance of the tree can be pruned during the dormant period.

5. Turn the basin: the black pine bonsai is usually turned once every 3 to 5 years, and it is suitable to be carried out from February to March. When turning the basin, it is necessary to keep the original basin soil intact, remove 1 inch and 2 old soil, cut off overgrown roots, as well as withered and rotten roots, and trim some unnecessary branches and leaves to maintain the balance between the upper and lower parts of the basin soil. If the capacity of the original basin is not enough, it can be replaced with a slightly larger new basin, and the planting method is the same as that of the upper basin.
