In the Olympic National Park in Washington State, a "tree of life" stands persistently on the edge of a cliff caused by the erosion of flowing water. Some call it the Immortal Tree of Magic, while others praise it as a symbol of perseverance.
The tree's roots were already suspended in the middle, exposed to the soil, and it looked as if it had clung to the cliffs on either side for its precious life. Amazingly, it has stood on a cliff for many years, and although it can only barely take root in the soil, it still grows new leaves and shoots. While many of the region's healthy trees have succumbed to the unpredictable weather, the Tree of Life has struggled year after year, failing even by the harsh storms that have plagued the West Coast for so long.
The "Tree of Life" is a Siga spruce tree, and since it has not yet been officially named, it has been given many names such as "Tree of Life" and "Escape Tree". The hollow below is cleverly named the "Root Cave".
It is reported that the cave appeared under the "Tree of Life" because the streams that flowed into the sea gradually took away the soil here over the decades. No one knows exactly how many years the tree's "pose" has been maintained, or how it has performed such a miracle, but it is indeed a natural mystery worth watching.
This hanging tree is not the only wonder of the world, Bahrain also has a "tree of life". Probably 400 years old, the LARGE UNESCO-protected tree grows in the desert and is the only tree within a few kilometres of the neighborhood. In deserts where there is no apparent water source, the tree may survive because it has its own deep-rooted system that can reach groundwater.
In fact, except for this plant, whichse roots are all bare, most of the plants in nature are rooted in the soil (except floating plants, parasitic plants and epiphytes).
Floating plant duckweed
Floating plant hyacinth
Parasitic plant King Flower
Epiphytes Shiwei
Epiphytes wild orchid
Soil is the substrate for plant growth and development. Generally speaking, although the dry weight of plant roots is less than 1/4 of the dry weight of the entire plant body, its spread in the soil is sometimes wider than the space occupied by the aerial part of the plant body. Plants continuously absorb water, nutrients and air from the soil through their roots. Plant roots grow and respirate in the soil, requiring the soil to have the right temperature and ventilation conditions.
The mixed roots of Indian grass, magnet grass, and large-bearded miscanthus show the above-ground and underground and proportional relationship with the human body.
The effect of soil on plants depends on the physical, chemical and biological properties of the soil. Some of them directly affect plants, some indirectly affect plants, and some directly and indirectly affect plants. First of all, let's talk about the most basic properties of soil, that is, the relationship between the mechanical composition of soil and plants. The mechanical composition of the soil affects the moisture, temperature, air and nutrient conditions of the soil, and thus indirectly affects the life of the plant. Depending on the mechanical composition, soils can be divided into clay, sandy and loam.
