Mixing of Poplar and Korean Pine
The eastern mountain area of Northeast China is the hometown of Pinus koraiensis. In the natural state, many Korean pine species are associated with certain species of broad-leaved trees in the whole growth and development process, forming a coniferous and broad-leaved mixed forest. With the development and utilization of forest resources in forest areas, Korean pine forest is reduced in a large area, and the consumption of forest resources is very high. in order to restore forest resources as soon as possible, although the introduced varieties of larch and poplar grow rapidly, but it is not conducive to the full utilization of woodland productivity and the restoration of ecological community, and will cause the deterioration of woodland soil conditions and reduce woodland production.

Budding treatment of Pinus koraiensis Seeds with variable temperature
Korean pine is an excellent timber forest and food forest in Northeast China. Korean pine seed coat is thick and hard, with a layer of wax, impervious to water and air, tannin in the seed coat and abscisic acid in other parts. These affect the rapid germination of Korean pine seeds and make Korean pine seeds dormant for a long time. Under natural conditions, Korean pine seeds should be released from long-term dormancy. After maturing, the seeds are buried in winter-summer-winter and taken out in the spring of the third year before they can be sown. In recent years, due to the shortage of Korean pine seeds, the market price is high.

The law of carbon sequestration of aged Korean pine forest in Changbai Mountain was revealed.
On December 23, the project "study on carbon sequestration function of aged broad-leaved Korean pine forest in Changbai Mountain", which was conducted by the National Field Scientific observation and Research Station of Changbai Mountain Forest ecosystem in Jilin Province, passed the expert review organized by Changchun Branch of Chinese Academy of Sciences in Changchun. Experts believe that the integration of a variety of methods in the project, component flux change and process mechanism research has reached the international advanced level. As the main body of terrestrial ecosystem, the process and mechanism of forest carbon cycle play an important role in understanding the function of forest carbon sequestration and its impact and response to global climate change.

Large seedlings of Pinus koraiensis to build Mother Forest
Korean pine, Pinus, Pinus, evergreen coniferous trees. It is mainly distributed in Xiaoxing'an Mountains and Changbai Mountain in China. Pinus koraiensis forest is the top community in this area, which plays an important social, ecological and economic role. In the early days of the founding of New China, in order to meet the needs of economic construction, excessive cutting of Korean pine trees was carried out, resulting in a large reduction of Korean pine trees. at present, there are only about 5 million mature Korean pine trees. Therefore, the massive, rapid and high quality construction of Pinus koraiensis mother forest is important for the restoration and development of the top community of Pinus koraiensis forest in Xiaoxinganling and Changbai Mountains.

What is the distribution area of Korean pine species?
The distribution area of Korean pine species is that Pinus koraiensis is produced in the mountains of Heilongjiang, Jilin and Liaoning at an altitude of 300 to 1800 meters above sea level. The natural distribution is roughly consistent with the extension of the Changbai Mountain and Daxing'an Mountains. Beijing and Shandong Mount Tai, Laoshan, Kunqu Mountain and other places have been introduced and cultivated. Pinus koraiensis adapts to light conditions in a large range, and the light requirement increases gradually with the increase of tree age. Most like the mountain dark brown forest soil with deep, fertile and good permeability. Pinus koraiensis is a shallow-rooted tree species with underdeveloped main roots and wide horizontal distribution of lateral roots, which is beneficial to extreme soil cultivation.

bark rot of Korean pine
Pine bark rot disease is also called drooping branch disease, soft branch disease, dead branch disease, withered shoot disease, is a branch ulcer disease, mainly harmful to pine species. Symptoms: The disease harms the bark of the branches of young Korean pine trees, and can also occur at the base of the trunk when it is serious, causing canker disease. The pine needles above the infected parts turned yellow-green to greyish green, and gradually turned brown to reddish brown. The injured branches shrink and wrinkle due to water loss, and the needle drop marks are slightly enlarged.

Identification and control of red wood bark elephant, a pest of Korean pine
Why is the red wood bark elephant an important pest of young Korean pine trees? Because the larvae of the red wood bark elephant drill under the skin of the branches of Pinus koraiensis, causing the main and lateral shoots to die. It not only affects the growth of Pinus koraiensis, but also makes the branches dry and split, weakens the growth of the tree, and leads to the invasion and harm of other diseases and insect pests. Moreover, because most of the life cycle of the insect is spent under the bark of branches, it is difficult to control. Once it happens in the forest, it may bring serious consequences of deforestation. How to identify the mahogany elephant? The adult is a small beetle, which belongs to

Techniques of rebuilding Pinus sylvestris var.mongolica young forest into Korean pine nut forest
In recent years, the construction of Korean pine fruit forest and Korean pine nut forest in Heilongjiang and Jilin provinces has developed rapidly. Some places regard the development of Korean pine fruit forest as the way to get rich, and large-scale Korean pine fruit forest has been established. However, due to the deviation in people's understanding, they ignore the selection of fine seed spike grafting to build forest, and the selected seed spike is rarely identified. The establishment of Korean pine nut forest like this without selection can not guarantee the yield and quality of seeds. What's more, it can not guarantee prematurity, high yield and stable yield. It has been proved by practice that the juvenile of Pinus sylvestris var. mongolica
