Chenshan Hongxinshan enjoys the reputation of “famous in the country and in the southeast”. In the pre-Qing Dynasty, Chenshan Hongxinshan was praised as the “closed wood” of Jiangxi and became a tribute to the court. It was also exported to Southeast Asia. In 1959, the 10th anniversary of the founding of New China, Chenshan Hongxin Chinese fir was first exhibited in the Beijing Agricultural Exhibition Center as a treasure of high-quality wood in China. It was praised by Chinese and foreign people. In 1977, the Chairman Mao Memorial Hall was built. 100 cubic meters of stone. National key projects such as the Beijing Olympic venues have also selected Chenshan Hongxinshan as a special material.

Chenshan Red Heart Fir is the best provenance group of Chinese fir with local characteristics. It is naturally distributed in the Anshan Chenshan forest area at the junction of Wugong Mountain, Anfu, Yongxin and Lianhua counties in the middle of Luojing Mountain Range in Jiangxi Province. It is 114°07′ to 114°22′ in the east and 27°11′ to 27° in the north. Between 17', it has three towns and five towns (an town) in Anfu County, namely Chenshan Forest Farm, Yingshang Forest Farm, Wugong Mountain Forest Farm, Pengfang Township, Yangmen Township, Jintian Township, Yantian Town and Yangxi Town. . Chenshan Hongxinshan is named for its relatively large proportion of the xylem of the near-medullary heart, which is named as oily chestnut brown. Its special quality is mainly straight, uniform and uniform, with small diameter and thick sections, and the material is light and tough. The texture is beautiful, especially its reddish anti-corrosion, fragrant aroma, and high proportion of red hearts. Chenshan Hongxinshan is a unique tree species in Jiangxi, which is naturally distributed in Chenshan Forest District and Wugong Mountain in Anfu County. But what is different is that most of the xylem of the near core is oily chestnut brown, red heart and corrosion resistance, less diameter, less fragrant, straight stem, high yield. Zeng Zhiguang, a researcher at the Jiangxi Academy of Forestry, has been studying Chenshan Hongxinshan for more than 40 years. His assessment of Chenshan Hongxinshan is: fast-growing, stable in material, and will not be mutated in other Chinese fir producing areas. The generalized heritability reaches 0.62~0.87. Adapt to planting in the suitable areas of Chinese fir in Jiangxi and surrounding provinces. In the 1970s, Chen Shanhong Xinshan participated in the national provenance test twice. The results showed that among the 43 provenances, the high yield of Chenshan red cedar was ranked 15th, and the height of tree height and DBH exceeded the national standard of fast forest. According to the investigation of the relevant state departments, the red heart rate of Chenshan red heart is about 40% higher than other excellent provenances. “A spring snowstorm in the spring of 2008 raided Anfu. Most of the exotic firs introduced in the other forest farms in the county in the 1950s and 1960s suffered from devastating damage. However, the Chenshan red heart fir stood proudly in the 'Berry. Chen Shan's every hill." This is not a fantasy, but a fact.

Chenshan Hongxinshan quality technical requirements I. Site conditions The production area is 200m to 1000m above sea level, the slope is 20° to 45°, the soil is red soil, yellow red soil and yellow soil. The soil texture is deep and fertile, loose and moist, well-drained loam. , pH 4.8 to 5.5. Second, cultivation management Selection of seeds and cuttings: Select the seedlings of Pinus sylvestris var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. var. The blade, the incision flat bottom or the horseshoe shape can be used. 2. The requirements for seedlings for afforestation are as follows: (1) Seedling requirements: ground diameter u0026gt; 0.50 cm, seedling height u0026gt; 30 cm, root length u0026gt; 20 cm; (2) clonal seedling requirements: ground diameter u0026gt; 0.50 cm, Seedling height u0026gt; 40 cm, root length u0026gt; 25 cm. 3. Planting: Planting time is from December to March, and cloudy planting is most suitable after cloudy; planting density is 2,505 plants/ha; planting should be done with Shugen, planting depth, planting, compaction, planting depth for seedling height 1/3 to 1/2, the soil is slightly above the ground. 4. Tending management: strip-shaped land preparation with inter-band cutting, with surface loose soil weeding; hole-like land preparation with the expansion of joints year by year; when planting, we must dig grass roots, shrubs, buds, and soil, the depth of loose soil is about 10cm; In the first to third years, twice a year, once every year from May to June, from September to October; after the fourth year, only the miscellaneous irrigation, grass and vines that hinder the growth of young trees are removed. 5. Fertilization: In the young forest stage, proper fertilization. The base fertilizer is mainly organic fertilizer and calcium magnesium phosphate fertilizer. Apply urea, calcium magnesium phosphate fertilizer in the 8 to 10 years of life, and open the ditch along the tree trunk. 6. Thinning: When the forest age is 8 to 10 years, it adopts one-time thinning, which is small and large, and it is strictly prohibited to cut the big hair and open the skylight. After thinning, the density is ≤1200 plants/hm2. Environmental and safety requirements: The use of pesticides, fertilizers, etc. must comply with relevant national regulations and must not pollute the environment. Third, the harvesting age is determined to be 35 to 40 years, the forest tree diameter is ≥24cm, the standing stock is 525 m3/hm2 to 600 m3/hm2, and the large diameter material is 225 m3/hm2 to 300 m3/hm2. 90 m3/ hm2 to 150 m3/ hm2. Fourth, the quality characteristics 1. Sensory features: The project's external appearance is straight and straight, the texture is beautiful, the red heart of the xylem near the heart is large and the oil is bright and lustrous, the sapwood is small and the white endurance is tough and savoury. The taste is rich and aromatic. Physical and chemical indicators: the basic density of the project indicators, g/cm30.2987～0.3357 wood late wood rate, %22.6～27.3 wood fiber length, um3400～3763 forest chest height red ratio,%39.4～61.23. Safety and other quality technical requirements: Product safety and other quality technical requirements must comply with relevant national regulations.
