Grafting technique of Pinus koraiensis by terminal bud split grafting
Pinus koraiensis (PinuskoraiensisSieb.etZucc.) is a tall tree of Pinus family with a straight trunk. The average height of the natural forest of Pinus koraiensis can reach 250m, the DBH can reach 40~80cm, and its life span can reach 30000years. In the place where the growth conditions are suitable, the height of the tree can reach 40m, the DBH can reach 200cm, and the life span is about 500years. It has excellent material, straight texture, strong pressure resistance, rich resin, strong decay resistance and high technological value.

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.

Seed collection time and method of Pinus koraiensis?
The time and method of seed collection of Pinus koraiensis are as follows: the number of fruiting trees in the 80-100-year-old stand of Pinus koraiensis accounts for more than 91%. In order to solve the problem of seed shortage of Pinus koraiensis, clonal seed orchard has been established, but it has not borne a lot of fruit at present. On the other hand, the stand with good site conditions and strong growth in the natural forest should be designated as the mother forest, and the tending management should be strengthened to prepare for seed collection. Korean pine cones mature from September to early October, when the cones change from green to yellowish green, some seed scales crack and enter the early ripening stage. After that, the seed scales gradually turned yellow, and individual cones began to fall off.

Planting and raising seedlings of Pinus koraiensis?
The method of sowing and raising seedlings of Pinus koraiensis is: spring sowing is suitable. The northeast region is better from mid-April to early June. Sowing or strip sowing is OK. In recent years, the seeds are usually sown with wide strips, with a width of 8 to 10 centimeters. After sowing, the soil is suppressed once and then covered with soil, which is about 2 cm thick. If it can be irrigated in time, no grass can be covered after sowing, and all-light seedlings can be raised. In order to kill weeds, before emergence after sowing, 3 grams of herbicide per square meter, 1 gram of atrazine or 2 grams of promethazine can be sprayed on the bed surface. Do not irrigate within 10 hours after spraying. The sowing rate of Korean pine is 3000 to 37 per hectare.

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.

Growth environment and growth characteristics of plane tree
Sycamore trees like light, warm and humid climate, cold tolerance is not strong; like fertile, moist, deep and well-drained soil, can grow on acidic, neutral and calcareous soil, but should not be planted in stagnant water depression or saline-alkali land, and is not resistant to grass famine. Stagnant water is easy to rot roots, which can be killed after five days of waterlogging. It usually grows well in plains, hills and gullies. Deep roots, stout taproots, weak sprouting, generally not suitable for pruning. The growth is fast and the life span is long. The leaves are late, but the leaves fall early in autumn. Have strong resistance to many kinds of toxic gases.
