What are the common garden trees?

Its remarkable features are:

Red leaves with green stems have excellent ornamental value; Males have no flying flocs and do not pollute the environment; The branches are green, straight, smooth and not cracked. The crown is well branched, with large opening angle and uniform distribution; The wood is fine and white, and the material is good; Strong stress resistance, wide planting area, cold tolerance (seedlings at MINUS 30 degrees, no smoking), drought resistance and salt tolerance. Especially suitable for planting in western, northwest, alpine, arid and semi-arid areas of China;

High survival rate, strong rooting ability, strong physiological activity of healing tissue and strong regeneration ability of cambium; It is the best grafting tree species found at home and abroad at present, and its grafting affinity is unmatched by any poplar variety.

2. Platanus acerifolia

Ecological habits: like light, like humid and warm climate, and cold-resistant. The requirements for soil are not strict, but it is suitable for slightly acidic or neutral soil with good drainage. Weak alkaline soil can grow, but it is easy to turn yellow. The distribution of root system is shallow, so it is easy to be injured and inclined during typhoon. Strong anti-air pollution ability, the blade has the function of absorbing toxic gases and dust retention.

This kind of tree has tall trunk, lush branches and leaves, rapid growth, strong adaptability, easy survival, pruning resistance and smoke resistance, so it is widely planted as a street greening tree and a fast-growing timber tree. It has strong resistance to toxic gases such as sulfur dioxide and chlorine.

Distribution: It is native to southeast Europe and west Asia and has a long cultivation history. According to records, it was introduced into China in the Jin Dynasty. There is an ancient tree called Quhan Tree or Kumarajiva Tree in Huyi District, Xi City, Shaanxi Province.

3.pine trees

growing environment

Soil requirements: Try to plant in fertile areas to ensure the healthy growth of pine trees.

Shade tolerance: Most pine trees like light, and their morphology is reflected in sparse crown distribution and strong natural pruning ability, so physiologically, their compensation points will not be the same as other tree species.

Drought resistance: If the soil moisture content is too high, it will seriously affect the normal growth of pine trees.

Growing climate: the distribution of pine trees is significantly different. Generally speaking, Pinus sylvestris var.mongolica. Quercus mongolica and panax quinquefolium have strong cold tolerance, so the requirements for heat in planting are not high.

4. Italian poplar

Growing environment: rapid growth and straight branches. Positive tree species. Like warm environment and moist, fertile and deep sandy soil, it has strong resistance to poplar brown spot and sulfide.

5, red maple

growing environment

Subtropical tree species prefer humid, warm climate and cool environment, are more resistant to shade and cold, and avoid sun exposure, but they can grow in full light in spring and autumn. The soil requirement is not strict, it is suitable for growing in fertile acidic or neutral sandy loam rich in humus, and it is not tolerant to waterlogging.

Hongfeng likes warm, humid and cool climate. It likes light, but it is afraid of the scorching sun. It is a neutral shade tree species. In summer, when it is attacked by dry and hot wind, its leaf edge will shrink and its bark will be scorched at high temperature. Although Hongfeng likes warmth, it is cold-resistant. In the Yellow River basin, the temperature is as low as -20℃ in winter, but as long as the environment is good, it can still overwinter in the open air. As for the north of the Yellow River, potted plants should be used, and it is advisable to go indoors in winter.

Acer truncatum can adapt to the soil pH value range of 5.5~7.5, so it can grow in slightly acidic soil, neutral soil and calcareous soil.
