There are more than eighty species of pine trees in the world, and they are widely distributed, and can be used for ornamental, medicinal or industrial manufacturing purposes. Today we will introduce how much the saplings of the Korean pine cost per tree and what grafting methods there are.

1. A brief introduction to the Korean pine

1. The origin of the Korean pine

The Korean pine is an evergreen tree that can reach 40 m in height. It is produced in China from the Changbai Mountains to the Xiaoxing'an Mountains in the northeast, and often forms mixed forests with Picea jezoensis and Picea koraiensis. It is also distributed in parts of Japan, Korea, and Russia.

2. The morphology of the Korean pine

The diameter at breast height of the Korean pine is about 1 m. The bark of young trees is grayish brown, while the bark of large trees is grayish brown or gray, with longitudinal cracks forming irregular rectangular scaly blocks, and after the flakes fall off, the red-brown inner bark is exposed. The needles of the Korean pine are basically in bundles of five, thick, hard, straight, and dark green, with fine serrations along the edges. Every year in June it produces red-yellow male flowers and green-brown female flowers. The cones are conical-ovate, conical-long-ovate, or ovate-oblong, and after maturity they slightly open to expose the seeds or do not open. Generally, the cones mature in September and October of the following year after flowering.

3. The value of the Korean pine

The graceful posture of the Korean pine makes it an ideal tree species for greening landscapes, so planting it along sidewalks, roads, and parks is excellent. The seeds of the Korean pine are also called sea pine nuts, a green and healthy food that can be made into candy and pastries, and can even replace vegetable oil for cooking. Using pine nuts as medicine is very effective for tonifying the kidney and replenishing qi, nourishing blood and moistening the intestines, and nourishing and strengthening the body. In addition, the Korean pine is also a precious economic tree that can be used as timber for construction, ships and vehicles, bridges, furniture, and boards, and can also be used to make non-woven fabrics, paints, and lubricating oil.

2. How much does a Korean pine sapling cost per tree?

The price of Korean pine saplings varies depending on the place of origin, purchase quantity, purchase time, specifications, and so on, so the editor of Tuliu.com will use the following as examples for everyone's reference.

1. For 4-year-old Korean pine saplings from Dalian, Liaoning, with a trunk height of 0.6M, soil ball diameter of 0.2M, and diameter at breast height of 0.1M, the price for a wholesale purchase of more than 10,000 trees is 0.8 yuan/tree;

2. For 1-5 year Korean pine saplings from Tonghua, Jilin, with a height of 0.1-0.5M and diameter at breast height of 0.3-0.6CM, pagoda-shaped open-field Korean pine saplings, the price for purchasing more than 10,000 trees is 1 yuan/tree.

Therefore, for different tree ages, specifications, and places of origin, the sapling prices are also different. Everyone should choose according to their own circumstances.

3. What grafting methods are there for Korean pine?

Generally, there are three grafting methods for Korean pine:

1. Graft onto Korean pine rootstock seedlings cultivated in the nursery. After one year, plant the grafted seedlings bare-root on the mountain. In addition, in the year of grafting, it is advisable not to untie the plastic strip; after planting on the mountain the following year, it can then be untied;

2. On afforestation land, plant 4-5 year old rootstock seedlings at different row spacings such as 3×3M, 4×4M, or 3×5M, and carry out grafting on site. In May of the following year after grafting, remove the plastic strip, and for those whose cuts have completely healed in the year of grafting and whose scions are growing well, unbinding can also be carried out in July;

3. Graft onto well-cultivated nutrition cup seedlings and carry out transplanting and planting;

4. During grafting, note that the grafting site of the scion and rootstock should be wrapped and bound with plastic strips. After survival, timely support should be provided, which is relatively beneficial to the survival and growth of the saplings. In addition, after the grafted seedlings are planted, 5-7 consecutive years of tree vigor management are needed, that is, in February-March each year, carry out a comprehensive pruning and shaping of the tree body, cutting off the tips of the rootstock side branches that affect the growth of the scion, so as to ensure that the growth of the scion is always in the position of the main branch. In the first few years, it is only necessary to build up the rootstock side branches; later, cut the side branches again. When the grafted seedlings form complete young trees, the pruning work can be ended;

5. During its growth management process, attention should still be paid to the invasion of pests and diseases such as leaf spot disease, scarab beetles, bagworms, and red spiders. It is best to do preventive work in advance. Plants showing disease should be treated promptly, and severe cases should be removed promptly to avoid affecting other healthy plants.

The Korean pine is now listed as a national second-class key protected wild plant in China, so everyone must not damage or cut it down. Of course, artificially planted Korean pines can still be reasonably utilized and used.
