What kind of green seedlings are good?
What tree species will be better for this year's landscape planting seedlings in the tree-planting season? A few days ago, the Provincial Forestry Bureau recommended to the majority of farmers a number of famous forest trees that are suitable for sale. The characteristics of these tree species are described below for reference. Songyang Maqin Mushroom Wood Variety: This tree species is of good quality. Seedlings grow fast. The annual growth is as high as 80-100 cm. The annual growth after seedling afforestation is more than 100 cm. When afforestation is made, the 1-year-old height is 60-80 cm. Strong seedlings are good, and “four sides†of afforestation can be planted with large seedlings. In the afforestation areas, soil with deep soil, fertile soil, and low groundwater level is suitable, and it is suitable for planting throughout the province. Poplar Fine Clone--Black Poplar No. 121: This species had rapid growth at the early stage on the non-saline plain beach, with excellent growth of sprouts, salt and alkali resistance, rapid growth on sea salt with a salt content of 0.3% or less, and moderate crown width. With less main lateral branches, strong wind resistance, and good wood quality, it is suitable for the cultivation of timber forests in the pulpwood industry and the construction of coastal shelterbelts in seawater with a salt content of 0.3%. Nozo No. 03 and Noguchi No. 043: Straight trunks, strong cold resistance, and normal growth at minus 5.1 degrees Celsius without freezing and freezing. With seedling height 15-30 cm seedlings afforestation, afforestation throughout the year. Suitable for planting in areas south of Ningbo and Zhoushan. The excellent family of Chinese fir – Dabaozi No. 30, Hunan: This species grows rapidly and grows extremely vigorously. The average tree height at 10 years is 8.3 meters, and the average diameter at breast height is 12.6 centimeters. The trunk is straight and full, and the disease resistance is strong. However, the material is not ideal and is moderate. Suitable for planting throughout the province. Large-leaved cedar: The initial growth was slightly slower. Ten years ago, the height of tree growth was 30-40 cm. After 15 years, the growth of tree height and diameter increased significantly. The tree trunks are straight and straight, the tree crowns are narrow and long tower-shaped, the branches and scales are dense, the wood texture is fine, the structure is uniform, there is aroma, corrosion resistance, and afforestation can be properly planted. It is suitable for planting in the mountains and hills of the whole province. It can also be used as a garden ornamental tree. Japanese cypress: under the same site conditions, the growth rate is higher than that of Pinus taiwanensis and Pinus sylvestris. It is close to the Chinese fir and cedar, and it is of good quality. It is an excellent material for construction, shipbuilding and furniture. Strong resistance, low temperature resistance, snow pressure resistance, strong wind resistance, antifreeze, less pests and veterinary diseases. It is suitable for afforestation of mountains and hills in the province, islands and poor growth of Chinese fir and cedar, or black pine forests for remoulding remnants, and replanting of larch and Pinus sylvestris forests. Japanese cypress: In suitable conditions, the growth rate exceeds Japanese cypress. The material is tough and easy to process. It is an excellent construction material. The forest land does not need to be used to make mountains. It is only necessary to carry the grass or plant large-scale land preparations. In the same year, it is only necessary to cultivate grass. It is suitable for hilly sites, barren hills, pine and cedar, poorly planted sites in the province.
