Is fast growing eucalyptus acidic or simple?

1.Fast-growing eucalyptus is an evergreen tall tree, with more than 600 species. There are periodic dead leaves falling off throughout the year, and most varieties belong to tall trees, and a few are small trees and shrubs.

2.The vast majority of eucalyptus trees are native to mainland Australia. A small part grows in neighboring Indonesia, the Philippines and so on.

3.Therefore, fast-growing eucalyptus does not have a clear distinction between acidic and alkaline, but its leaves contain a lot of toxins. Generally only koalas can be eaten!

Acidic. 1. Eucalyptus is a "pumping machine" Eucalyptus is a fast-growing and high-yield forest, which has a great demand for soil moisture, and the introduction of eucalyptus in a large area will lead to a decline in the groundwater level, and the ability to maintain water is very poor.

2. Eucalyptus is a "fertilizer extractor" Eucalyptus has a great demand for fertilizer and nutrients in the soil.

Fast-growing eucalyptus trees should be acidic.

Alkaline, plants are alkaline, animals are acidic.

Fast-growing eucalyptus refers to the hybrids of Eucalyptus macrophylla*Caudal Eucalyptus, Eucalyptus macrophylla*Red Eucalyptus, Eucalyptus willowifolia*Eucalyptus longensis and Eucalyptus caudal*Eucalyptus microphylla, etc., with many strains, named after the series code. The characteristics of each strain are different: the one that grows fast rolls up to 10 meters a year; cold-resistant ones are more resistant to two degrees of low temperature than the original species; There are also disease-resistant.

There are two main ways of seedling propagation: tissue culture and cuttings, and it is necessary to regularly select superior plants as seed sources. If the site conditions are good, it can be harvested for five years, and the yield per mu is eight cubic meters of woodThe rate of economic return (economic maturity) is more than 20% years.

The wood is mainly made of plywood, and the secondary wood is used to make high-grade coated paper or copy paper.

1.Natural forests are destroyed. Forest land is needed to create fast-growing forests.

2.The single tree species causes simple plant communities, destroys the ecology, and causes serious soil erosion. The growth cycle of fast-growing forest is very short, and because it is developed as a cash forest crop, it is often unable to form the ecological chain that the mountain forest should have in the area where it is planted, and the vegetation is single, which causes great damage to the living environment of wild animals, birds and insects.

3.Those who demand more than return soil fertility have experienced destruction.

4。Excessive use of chemical fertilizers, poisoning the soil.

5.Invasive alien species, most of the fast-growing forest species introduced in the south are alien species, such as eucalyptus, which has strong vitality and is difficult to break roots, which threatens native species and changes the entire natural ecological balance. Native trees in fast-growing forests are difficult to survive and other crops cannot be grown.

6.Fast-growing forests usually have the ability to absorb water and fertilizer, which often makes the plants around the fast-growing forest unable to survive, and destroys the diversity of vegetation searched by the first party. At the same time, because of his domineering ability to absorb water, people who are familiar with this plant usually give him the title "pump".

In areas where "pumping" is planted, after many years, it is often found that the soil is loose and desertified. Often, in the cols with dense vegetation, we can find springs and streams. However, where fast-growing forests grow, it is difficult to find springs and streams in even the densest areas due to frequent logging.

7.The income period is short, and the first three rounds of planting generally have better economic benefits, but even if a large amount of chemical fertilizer is used in the future, it is difficult to have better forest income.
