How much is the seedling of Pinus koraiensis, a precious tree in the north? What are the grafting methods?

There are more than 80 species of pine trees in the world, and they are widely distributed, whether they are ornamental, medicinal or industrial. Today we are going to introduce how much is the seedling price of one of the red pine trees and what are the grafting methods?

I. A brief introduction to the red pine tree

1. The producing area of Korean pine

Pinus koraiensis is an evergreen tree up to 40 meters high, which grows from Changbai Mountain to Xiaoxing'an Mountains in northeast China and is often mixed with fish scale pine and red spruce. In addition, it is also distributed in some parts of Japan, fried incense, South Korea and Russia.

two。 The morphology of Korean pine

The breast diameter of the red pine is about 1 meter, the bark of the young tree is grayish brown, and the bark of the big tree is grayish brown or gray, which split longitudinally into irregular rectangular scaly pieces, and the lobes will expose the reddish-brown endothelium when the lobes fall off; the needles of the red pine are basically a bunch of five needles, the needles are thick, hard, straight dark green, and there are serrated edges. Red-yellow male flowers and green-brown female flowers bloom in June every year. Cones are conical-ovoid, conical-oblong, or ovate-shaped, showing seeds slightly or not after maturity. Generally, cones mature in September and October of the following year.

3. The value of red pine trees

The graceful posture of Pinus koraiensis is an ideal tree species for greening the landscape, so it is very good to plant along the roadside, on the road and in parks. The seeds of Pinus koraiensis, also known as sea pine nuts, are a kind of green and healthy food, which can be used to make candies, cakes and vegetable oils. it can also be used as medicine for tonifying kidney and qi, nourishing blood and moisturizing intestines, nourishing fitness and so on. In addition, red pine is also a precious economic tree, which can be used as materials for buildings, ships, bridges, furniture and plates, as well as non-search, paint and lubricating oil.

How much is the price of Korean pine saplings?

The price of red pine seedlings will vary according to the origin, purchase quantity, purchase time, specifications and so on, so the following Tuliu.com editor will take the following as an example for your reference.

1. The wholesale price of more than 10000 4-year-old Korean pine seedlings with trunk height of 0.6m, soil ball diameter of 0.2m and DBH of 0.1m in Dalian, Liaoning Province is 0.8 yuan per tree.

two。 Pinus koraiensis seedlings for 1-5 years in Tonghua, Jilin Province, pagoda-shaped open-field Korean pine seedlings with a height of 0.1-0.5m and a DBH of 0.3-0.6CM are purchased at a price of 1 yuan per tree for more than 10000.

So different tree age, specifications and origin, seedling prices are not the same, we have to choose according to their own situation.

Third, what are the grafting methods of Korean pine?

Generally, there are three grafting methods for Korean pine trees:

1. The seedlings of Korean pine rootstocks cultivated in the nursery were grafted, and one year later, the bare roots of the grafted seedlings were planted up the mountain; in addition, in the year of grafting, it was advisable not to untie the plastic strip, and then unbound after planting in the mountain the next year.

two。 The rootstock seedlings of 4-5 years old were planted on the afforestation land according to the row spacing of 3 × 3m, 4 × 4m or 3 × 5m, and the plastic strip was removed in May of the following year. If the cut is completely healed and the scion grows well in the same year, it can also be unbound in July.

3. Grafting on the cultivated nutrient cup seedlings and transplanting

4. When grafting, we should pay attention to the grafting position of scion and rootstock with plastic strips, and timely grafting after survival, which is more conducive to the survival and growth of seedlings; in addition, grafted seedlings need tree potential management for 5-7 years after planting, that is, a comprehensive pruning of the tree body is carried out in February-March every year to cut off the top of the side branches of the rootstock 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 of Xiuqian, only Zhu Shao, the side branch of the rootstock, was needed to set up the side branch, and then the side branch was cut in the later stage. When the grafted seedling formed a complete young tree, the pruning work could be finished.

5. In the process of its growth and management, we should still pay attention to the damage of diseases and insect pests such as spot disease, beetle, big bag moth and red spider, and it is best to do a good job of prevention in advance; plants with disease should be treated in time, and serious ones should be removed in time so as not to affect other healthy plants.

Now Korean pine has been listed as a second-class key protected wild plant in China, so we must not destroy or cut down, of course, artificially planted Korean pine can be reasonably used and used.
