Description :

　　White pine: The material is fine and the texture is straight. After anti-corrosion treatment, it can effectively prevent the invasion of mold, termites, and microorganisms, suppress changes in the moisture content of treated wood, reduce the degree of wood cracking, and extend the lifespan of wood to 40-50 years. Camphor pine. Mongolian oak grows in areas with cool summers, cold winters, and suitable precipitation. It is mainly distributed in the Greater Khingan Range of Heilongjiang Province, some mountainous areas west of Hailar in Inner Mongolia, and the northern part of the Lesser Khingan Range in China. Its Russian camphor pine variant. Mongolia has extremely abundant resources and is the main base for importing logs for Chinese enterprises. Cinnamomum camphora anti-corrosion material. Sand holly is widely used in Russia, including wooden walkways, pavilions, water corridors, flower stands, and fences.

　　The trail dock, children's education game area, flower table, garbage bin, outdoor furniture development, as well as students' outdoor work environment, hydrophilic environment, indoor and outdoor structures can all be used.

　　The growth habits of white pine:

　　1. It is a plant species with strong phototaxis and deep roots, which can adapt to ridges and sunny slopes with less water research in social soil, as well as drier sandy and gravelly soils or areas. It is mostly compared to pure forests or mixed with larch trees.

　　Figure 2. White pine is cold resistant, able to withstand low temperatures of -40 to 50 ° C, dry, and does not require soil moisture. The tree crown is sparse, the needles are sparse, the needles are short, the needle cuticle is keratinized, there are thick fleshy parts, there are stomata in the concave folds of the leaves, and the dry epidermis and lower epidermis are thick, which can reduce transpiration in the aboveground part. At the same time, on dry sand dunes, the main roots are generally 1-2 meters deep, up to 4 meters deep, and the lateral roots are distributed in the sand layer of 10-50 centimeters on the surface. The root system extends outward and can fully absorb water from the soil.

　　3. "White pine" is a positive tree species with sparse crown and concentrated needles on the surface of the tree. When the forest lacks lateral light, the trunk naturally prunes quickly; When isolated or with sufficient lateral light, lateral branches and needles become lush, and young trees grow poorly under the canopy. Camphor pine. Mongolian oak has strong adaptability. It can grow well on sandy soils with poor soil nutrients and thin mountain gravel soils. More than 30 species of coniferous and broad-leaved trees have been planted in Zhangjiatai sandy land, but there are some differences in Pinus sylvestris var. mongolica. Mongolian oak can adapt to the environmental conditions of different parts of sandy land, and can grow even on mountain tops with poor conditions. In addition, it also grows well in sandy areas such as Yulin and Ikzhao League. Areas with excessive moisture or stagnant water are not conducive to their growth, and they prefer acidic or slightly acidic soils. The black calcareous soil in the thin carbonate meadow of Zhaodong Experimental Forest Farm, Heilongjiang Academy of Forestry, has a total salt content of 0.08% at pH 7.6-7.8 and grows well. If the pH value exceeds 8 and the sodium bicarbonate content exceeds 0.1, it will have adverse effects.
