What are the roots of pine trees like?

The roots of pine trees are shown in the figure below. Macrofungi often grow on the roots of pine trees. Some of them are wood rot fungi, which can decompose pine trees and cause root rot of trees; Some are ectomycorrhizal fungi, which can exchange nutrients with pine trees to prevent trees from lacking nutrients, thus affecting their growth.

The height after maturity is 45 meters, DBH 1.5 meters; The bark is reddish brown, the lower part is grayish brown, and it splits into irregular scales; Branches spread flat or obliquely, with broad tower-shaped or umbrella-shaped crowns. Branches are born once a year, light yellow brown, without white powder, rare white powder and hairless; Winter buds are ovoid or cylindrical, brown, with sharp tips, filiform bud scales, long and tapering tips, and slightly bent down.

Extended data:

Pine roots have strong adaptability to soil, so pine trees can grow in various types of soil, but the soil will still have a direct impact on the growth trend of pine trees. Therefore, we should choose areas with fertile soil as far as possible to ensure the healthy growth of pine trees. If the area is relatively abundant in water, pine trees should be planted in acidic soil as far as possible, but some varieties are more suitable for planting in alkaline soil.

In addition, from the ecological point of view, pine is the most common xerophyte, and it can survive healthily even in areas with very different climatic conditions. "The vast majority of pine trees grow in areas with dry conditions and thin soil. Among them, two-needle pine has stronger drought resistance than five-needle pine. It can be seen that if the soil water content is too large, it will seriously affect the normal growth of pine trees.
