What are the common garden tree species

1, Chinese red poplar

Significant features:

Green pole red leaves, excellent ornamental value; male no flotsam, do not pollute the environment; rods green, straight and smooth not cracked. The crown is complete with many branches, large opening angle, uniform distribution; wood is fine and white, good material; strong resistance, suitable for planting in a wide range of areas, cold-resistant (seedlings at minus 30 degrees, do not pumping), drought-resistant, saline-resistant. Particularly adapted to China's western, northwestern, alpine, arid, semi-arid areas planted;

Planting a high rate of survival, rooting ability, the physiological activity of the healing tissues, strong regenerative capacity of the formation layer; is the best grafted species found at home and abroad up to the grafting affinity is incomparable to any of the varieties of poplars.

2, three-ball bellflower

Ecological habits: light-loving, prefer humid and warm climate, hardy. The soil requirements are not strict, but suitable for slightly acidic or neutral, well-drained soil, slightly alkaline soil can grow, but prone to yellowing. Root distribution is shallow, easy to victimize the typhoon and inverted. Resistance to air pollution is strong, the leaves have the role of absorbing toxic gases and stagnant dust.

This kind of tree trunk is tall, luxuriant branches and leaves, rapid growth, strong adaptability, easy to survive, pruning resistance, resistance to smoke, so it is widely planted for avenue greening species, also for fast-growing timber species; it has strong resistance to toxic gases such as Ryukyu dioxide and chlorine gas.

Distribution range: native to southeastern Europe and western Asia, cultivated for a long time, according to records of the Jin Dynasty in China that has been introduced. Shaanxi Province, Xi'an City, Shuangyi District, there is an ancient tree, called the expectorant tree or the Hatchet Tree.

3, pine

Growing environment

Soil requirements: should try to choose fertile soil area planting, in order to ensure the healthy growth of pine trees.

Shade tolerance: the vast majority of pine trees like light, its shape is specifically manifested in the crown distribution sparse, natural branching ability is very strong, so in terms of physiology, its compensation point will not be the same as the height of other trees.

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

Growth climate: the distribution of the origin of the pine tree has a significant difference, in general, camphor pine and five-needle pine, etc. has a strong cold resistance, so the planting of the heat requirements are not high.

4, Italian poplar

Growth environment: fast-growing, straight pole. Positive species. Prefer warm environment and moist, fertile, deep sandy soil, strong resistance to poplar brown spot disease and sulfide.

5, red maple

Growing environment

Subtropical species. Prefer humid, warm climate and cool environment, more tolerant of shade, cold, avoid sun exposure, but spring and fall can grow in full light. The soil requirements are not strict, suitable for growth in fertile, humus-rich acidic or neutral sandy loam, do not tolerate waterlogging.

Red maple like warm and humid, cool climate environment, like light but afraid of the sun, is a neutral shade species, in the summer when the dry hot wind blowing will cause the edge of the leaf withered roll, high temperature sunburn will also damage the bark, red maple although like the warmth, but it is still hardy, in the Yellow River Basin area, the winter temperature is as low as-20 ° C, but as long as the environment is good, you can still overwintering in the open ground. As for the north of the Yellow River, it is appropriate to pot, winter into the room is appropriate.

The red maple can adapt to the range of soil pH5.5~7.5, so it can grow in slightly acidic soil, neutral soil and calcareous soil.
