Where is the dawn redwood mainly distributed? A detailed explanation of the price of a 30-year-old tree and the planting season
The dawn redwood has strong adaptability, prefers moist conditions and grows fast, and is cultivated everywhere south of Beijing. Its wood is light and soft, and can be used for construction, boards, papermaking, and so on; its tree form is graceful, making it an ornamental tree for gardens. So where is the dawn redwood tree mainly distributed? What is the price of a 30-year-old tree? Which season is best for planting?
Geographical distribution
It is distributed in parts of the three counties of Lichuan, Shizhu and Longshan at the junction of the three provinces of Hubei, Chongqing and Hunan, with a vertical distribution generally at an altitude of 750-1500 m.
What is the price of a 30-year-old tree?
Dawn redwood price: First you need to understand the basic measurement methods for dawn redwood.
Dawn redwood measurement: There are two different purposes. 1: For timber such as (furniture and decoration), use a professional measuring tape for timber cubic volume to measure the cross-section; this is discussed in cubic meters, for example: what is the price per cubic meter. 2: For greening and afforestation, generally measure the meter diameter or breast diameter (measured at one meter).
Dawn redwood price: 1: If it is the first type used for timber, it is generally divided into finished and semi-finished products, with prices between 800-1150 yuan.
2: If it is the price of dawn redwood for greening, meter diameter 3-4-5-6-7-8-cm; 4.5-7.5-10.5-25-40-70 yuan; breast diameter 8-10 cm and height 8 m 80 yuan; breast diameter 10-13 cm and height 10 m 100 yuan; breast diameter 13-15 cm and height 12 m 200 yuan;
The above prices are from a report by the national-level Dafeng Dawn Redwood Base in August 2007; specifically, there will be a certain price fluctuation depending on the market and the requirements for dawn redwood.

Cultivation techniques
The planting season for dawn redwood can be from late autumn to early spring, and generally late winter is best. It should never be planted in the severe cold when the soil is frozen or during the growing season (summer), otherwise the survival rate will be extremely low. Seedlings should be dug and planted as they go, avoiding excessive water loss. If they are transported over a long distance, the seedling roots should be soaked in water after arriving at the destination. When transplanting large seedlings, they must be kept with a soil ball, a large hole must be dug, sufficient base fertilizer must be applied, fine soil must be filled in and pressed firm, and after planting they must be watered thoroughly. During the vigorous growth period, fertilizer should be applied as a top dressing, generally once, and attention should be paid to loosening the soil and hoeing weeds.
Hoeing weeds and loosening soil
Hoeing weeds and loosening soil means removing weeds and vines, loosening the soil to enhance air permeability, improving physical and chemical properties, creating a comfortable and good soil environment space, improving the life functions of the root system, promoting its robust and rapid growth, and laying a solid foundation for high yield and efficiency of dawn redwood. Hoe weeds and loosen the soil 2 times each year, and the tending effect is best in May-June and August-September, before the vigorous growth period of dawn redwood.
Moderate intercropping
In order to fully use the open space in the forest, improve land utilization, improve soil structure, and enhance soil fertility, legume crops or green manure can be appropriately intercropped within 1-2 years after afforestation. To avoid affecting the growth of the saplings, the intercropped crops should be kept 30-40 cm away from the saplings. Through intertillage, weeding and fertilizing of the crops, it can both play the role of cultivating instead of tending and increase income, achieving the goal of using short-term returns to support long-term growth.
Moderate pruning
In order to maintain ventilation and light transmission and create good space for the robust growth of the trees, moderate pruning should be carried out after the forest is established. It is best to carry out pruning after the dawn redwood sheds its leaves and before the beginning of spring. The pruning intensity is 1/4-1/3 of the total length of the crown, depending specifically on the growth condition of the trees.
