How much does a fast-growing eucalyptus sapling cost? A detailed explanation of the hazards of planting
Fast-growing eucalyptus is an evergreen tree with a very fast growth rate and a tall, upright trunk. The root system of fast-growing eucalyptus is very deep and extremely drought-tolerant, and it is planted in many places in our country. Besides having a certain greening effect, fast-growing eucalyptus trees can also be used as dyes and for papermaking, giving them high economic value. Let's take a look below at how much a fast-growing eucalyptus sapling costs per tree, and what its hazards are.
1. How much does a fast-growing eucalyptus sapling cost per tree?
The price of fast-growing eucalyptus saplings varies from place to place and is affected by height, crown width, place of origin, market conditions, purchase quantity, purchasing channel and so on. According to related websites, fast-growing eucalyptus saplings of 1.2-1.5m cost about 28 yuan per tree, with a minimum order quantity of more than 1500 trees; the specific price depends on the local nursery stock market conditions.
However, the market for planting fast-growing eucalyptus is no longer what it once was. Although eucalyptus can have high economic value, it also brings relatively many hazards, which will be described in detail below.
2. What are the hazards of fast-growing eucalyptus?
1. Causing severe soil damage
Eucalyptus has an enormous demand for soil fertilizer and nutrients. Wherever eucalyptus is planted, soil fertility declines or even becomes exhausted, and the original vegetation is severely damaged because it cannot obtain enough fertilizer and nutrients, causing land degradation, worsening soil and water conservation, and barren land; by then, introducing other plants simply will not allow them to survive.
2. Causing a drop in the groundwater level
Eucalyptus is a fast-growing, high-yield forest with a strong transpiration effect and an enormous demand for soil moisture. Introducing eucalyptus on a large scale will cause the groundwater level to drop, and its ability to retain water is very poor. Over time, the land surface becomes hard and compacted, and land desertification also occurs.
3. Suppressing and excluding other plants
Eucalyptus secretes a chemical substance that suppresses and excludes the growth of other plants, so that plants beneath the eucalyptus cannot grow at all, and it is extremely suppressive to local native, indigenous and original species. Once it grows, other species cannot grow, and the ecology will suffer subversive damage that is difficult to restore.
4. Releasing irritating odors that endanger human health
Eucalyptus itself is not toxic, but the rubber-based hydrocarbons it releases combine with carbon dioxide to form ozone, and the odor given off has an irritating and toxic effect on the human body. When planting eucalyptus, certain fertilizers and pesticides with strong toxicity and long-lasting toxic effects are applied; once these are applied to the land, they will be very difficult to clean away, greatly polluting water quality, and after people and livestock drink it, they will cause immeasurable harm. In addition, the odor given off by eucalyptus has an irritating and toxic effect on the human body and will threaten the health of local people.
The above is an introduction to questions such as the price of fast-growing eucalyptus saplings and the hazards of fast-growing eucalyptus. We hope it is of some help to you.
