Basic Introduction of Chenshan Red Cedar

Chenshan Red Cedar is a unique tree species in Jiangxi Province, naturally distributed in forest areas such as Chenshan and Wugong Mountain in Anfu County. Due to its shiny chestnut brown wood, most of its wood is resistant to rot, has a thick diameter and few nodes, and is fragrant. In addition, its main trunk is straight and its yield is high. It is known as the "Guanshang Wood" of Jiangxi and was presented to the imperial court in ancient times. It is also exported to Southeast Asia. In the 1970s, the central government transported 100 cubic meters of Chenshan red cedar from Anfu for the construction of the Mao Zedong Memorial Hall. Beijing Olympic venues and other national key projects have also selected it as a specialized material

Suitable living environment

Temperature: 16-18 ℃, daily average accumulated temperature above 10 ℃ is 4500-5600 ℃

Rainfall: Annual precipitation of 1200-1800 millimeters

Altitude: 400-800 meters in hilly areas, with an upper limit of 1400 meters

Soil: hilly red soil, mountainous yellow red soil, mountainous yellow soil

Quality and Technical Requirements

1. Site Conditions

Within the production area, the altitude is 200 to 1000 meters, the slope is 20 ° to 45 °, the soil is red soil, yellow red soil, and yellow soil, and the soil texture is deep, fertile, loose, moist, and well drained loam soil with a pH value of 4.8 to 5.5

2. Cultivation Management

1. Seed and spike selection: Select seeds from the red heart fir mother forest, seed garden, and spike collection garden within the production area. The seed quality should meet the relevant national requirements, and the spike should be semi woody, with a spike length of 8 to 10 centimeters, retaining leaves, and can be cut flat or horseshoe shaped

2. Seedling cultivation: Solid seedlings cultivated from red heart fir seeds and asexual seedlings cultivated from ear cuttings in the ear picking garden. The requirements for afforestation seedlings on the mountain are as follows:

(1) Requirements for seedlings: ground diameter>; 0.50 cm, seedling height>; 30 centimeters, root length>; 20 centimeters

(2) Requirements for clonal seedlings: ground diameter>; 0.50 cm, seedling height>; 40cm, root length>; 25 centimeters

3. Planting: The planting time is from December to March of the following year, and it is most suitable to plant on cloudy days after rain; The planting density is 2505 plants per hectare; Planting should be done with relaxed roots, deep planting, upright planting, and compaction. The planting depth should be 1/3 to 1/2 of the seedling height, and the soil cover should be slightly higher than the ground

4. Nurturing management: For strip land preparation, inter strip cutting is used, and strip surface loosening is used for weeding; The use of hole shaped soil preparation involves expanding the holes year by year; When nurturing, it is necessary to dig up all the grass roots, shrubs, remove the sprouts, and cultivate the soil. The soil should be loosened to a depth of about 10 centimeters; From the first to the third year, twice a year, once in May to June and once in September to October each year; After the fourth year, only remove miscellaneous shrubs, grass, and vines that hinder the growth of young trees<5. Fertilization: During the young forest stage, appropriate fertilization should be applied. The main base fertilizers are organic fertilizers and calcium magnesium phosphate fertilizers. Apply urea, calcium magnesium phosphate fertilizer at 8-10 years old, and create a circular ditch along the tree

6. Thinning: When the forest age is 8 to 10 years, one-time thinning should be used, with small cuts leaving large ones and poor cuts leaving excellent ones. It is strictly prohibited to "pluck large hairs" and "open skylights". The density after thinning is ≤ 1200 plants/hectare<7. Environmental and safety requirements: The use of pesticides, fertilizers, etc. must comply with relevant national regulations and must not pollute the environment

III. Harvesting

The main cutting age is determined to be 35 to 40 years. The diameter at breast height of the forest stands is ≥ 24 centimeters, and the standing timber volume reaches 525 cubic meters/hectare to 600 cubic meters/hectare. The production of large-diameter timber is 225 cubic meters/hectare to 300 cubic meters/hectare, and the production of medium diameter timber is 90 cubic meters/hectare to 150 cubic meters/hectare

Regional Location

Chenshan Red Cedar is a unique tree species in Jiangxi Province, naturally distributed in forest areas such as Chenshan and Wugong Mountain in Anfu County. Its uniqueness lies in the unique geographical, climatic, and soil conditions of the production area, which are very suitable for the growth of Chenshan red cedar

1. Excellent material. Chenshan red heart cedar has a high density, strong compressive strength, no warping or cracking, tough and corrosion-resistant, and a high proportion of red heart wood. According to a survey conducted by Jiangxi Academy of Forestry, the red heart ratio of Chenshan red cedar wood is as high as 40%, ranking first in the country. In 1979, Corea chenshanensis was collected as one of the national provenance test provenances of Chinese fir. In 1980 and 1981, seedling raising and afforestation tests were conducted at 55 test sites in 14 provinces (regions) of southern China. From 1997 to 1999, Jiangxi Academy of Forestry Sciences selected 10 test sites in 7 provinces (regions), including Longquan in Zhejiang Province, Mount Huangshan in Anhui Province, Shaowu in Fujian Province, You County in Hunan Province, Xianning in Hubei Province, Wuxuan in Guangxi Province, and Dexing, Tonggu, Anfu and Linchuan in Jiangxi Province, to study and analyze wood core samples. The results showed that the heart rate of Corea chenshanensis planted in Anfu pilot was the highest at 1.3m chest height, averaging 59%, nearly 9 percentage points higher than the average value of each pilot

2. Beautiful material color. The texture of Chenshan red cedar is straight, uniform and complete, with low sharpness and unique color. The heartwood is bright red, with a fragrant aroma and few sapwood

3. Fast growth. The experimental results showed that the high yield of Chenshan red heart fir ranked 15th among the 43 germplasm sources tested nationwide; According to the first survey of the 27 year old germplasm experimental forest, the growth rate of Chenshan red heart fir ranks fourth in the country. According to the investigation of the place of origin by Jiangxi Academy of Forestry, the height and diameter at breast height growth of 8-year-old Chenshan Red Cedar trees exceeded the national standards for fast-growing and high-yielding forests by 23.1% and 36.7%, respectively; 16 year olds account for over 20.0% and 28.2% respectively; Over 2.7% and 28.6% of 24 year olds respectively; 31 year old students account for over 43.7% and 39.0% respectively
