Propagation of Pinus sylvestris var. mongolica grafted Pinus koraiensis seedlings
Pinus sylvestris var. mongolica has strong adaptability, cold resistance, drought resistance and barren resistance. Grafting Korean pine with Pinus sylvestris var. mongolica as rootstock has the advantages of early flowering and fruiting, quick garden formation and good effect. 1 the preparation of scion 1.1 the selection of mother tree selects excellent mother tree as scion. The tree height, DBH, crown width, fruiting layer thickness, young fruit number, cone number, male and female flowers of each clone were measured in the selected area. at the same time, seed collection per plant, cone number, cone weight, seed yield, seed emergence rate, kernel emergence rate, empty shell rate, insect damage rate, 1000-grain weight and cone length and width were tested.

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.

Artificial promotion of seed setting of Pinus koraiensis
As a tree species with long rotation period, it is very important to excavate seed economic potential, shorten capital return period and solve recent economic income besides considering timber income. There are 800 hectares of Pinus koraiensis plantation in Fengcheng area, of which 3600 hectares have entered the fruiting period. In the bumper year, the average seed yield per hectare is 350 kg, and the total output value can reach 13 million yuan. Further increasing the seed yield of these stands can effectively boost the development of forestry economy in mountainous areas. We February 1998 sap flow before existing into knots

Seed treatment techniques of Pinus koraiensis
Pinus koraiensis (PonusRoraiensisSiebetZucc.), also known as Pinus koraiensis, Pinaceae. It is growing well in Kuandian area of Liaoning Province, and its wood material is soft and durable, edible and squeezable oil. it is a natural green food. In recent years, with the increase of the export volume of Korean pine seed kernel products, the commodity value of Korean pine is getting higher and higher, and the demand for Korean pine afforestation seedlings is also greatly increased, thus arousing the enthusiasm of the majority of seedling workers to raise Korean pine seedlings. Seed treatment is crucial in the process of seedling cultivation of Pinus koraiensis.

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.

Seed collection, storage and seedling raising techniques of Pinus koraiensis
1. Seed collection and preparation of Korean pine is a monoecious tree species, flowering in mid-late June, from flowering to cone maturity takes 15 months, Korean pine seed collection period can be as long as 4 months, cones can be picked or knocked down from trees in the early stage, cones can be picked from snow in the later stage. After the cones are collected, they are spread out to dry or dry in the shade for several days. when the scales are slightly opened, they can be prepared with artificial sticks. The seed emergence rate of natural forest cones is 13%-14%, and that of artificial forest cones is 30%, and the 1000-grain weight is 520 grams. Working in seed collection

Seed treatment of Pinus koraiensis before seedling cultivation?
The method of seed treatment before seedling cultivation of Pinus koraiensis: the seed shell of Pinus koraiensis is dense and thick, covered with wax, not permeable and breathable, and contains tannin and other germination inhibitory substances, so that it is difficult for seed embryo to germinate. Therefore, the seeds should be germinated before sowing. The commonly used false bud methods are as follows: first, the method of overwintering in the open air: soak the seeds in cold water for 2 to 3 days in autumn, remove and mix 2 to 3 times of wet sand and put them in the open cellar. The kiln site should be located in a place with high and dry terrain and good drainage. Cellar depth 1.2 to 1

Grafting of young Korean pine forest
1. The scions should be collected by the mother trees with good growth characters and strong fruiting ability in the seed orchard, and carried out in the early and middle of March in the year of grafting and before the sap began to flow. The collection site is the 2nd ~ 3rd Suaeda salsa branch of the trunk, and it is an one-year-old branch with strong growth. The thickness of scion should be about 8 mm. The scion should not be collected too much at one time, and each plant can control 15-20 branches to protect the excellent mother tree. The scion should be packed, moisturized, transported or stored in cellar after collection. Use the rural vegetable cellar to store, put 50 centimeters of ice at the bottom, put the scion into, seal

What are the characteristics of Korean pine species?
The characteristics of Korean pine species are as follows: evergreen trees of Pinaceae. It can be up to 50 meters high and 1.5 meters in breast diameter. The trunk is straight and complete, and the crown is conical. The tree can be more than 500 years old. It is one of the precious timber tree species in China. Because the trunk is straight, the material is good, the yield is high, the decay resistance is strong, and the technological value is extremely high. It is an excellent material for construction, aviation, electricity posts, sleepers, bridges, vehicles and ships. It is also a good raw material for making all kinds of moulds, plywood, musical instruments and sports equipment. In addition, Korean pine can also extract resin; bark can
