Eucalyptus trees are not toxic, nor is the water around the trees.
Eucalyptus is originally a green tree, but it grows very quickly and has a strong ability to absorb water and fertilizer, causing surrounding crops to fail to grow normally. But it itself is non-toxic, and eucalyptus can be used to extract sesame oil, paper, furniture, and fuel.
Eucalyptus is a fertilizer-loving crop. In order to promote its growth, a lot of fertilizer is sometimes applied, which has a certain impact on the water quality around it, but it is non-toxic.
Eucalyptus controversy:
Western Guangdong has a history of more than 50 years of eucalyptus cultivation. The export of processed wood chips has become a pillar industry in the area. So far, there have been no reports of eucalyptus trees releasing toxins that pollute the environment. . On the contrary, eucalyptus oil is also extracted as a valuable spice.
In 2014, in response to questions about whether locally grown eucalyptus trees would pollute water sources, relevant departments in Beihai City randomly selected water samples from Niuweiling Reservoir and took them to the testing department for testing. The final verification report showed that all indicators of water quality were normal.
Since the eucalyptus forest is an artificial ecosystem and an intensively managed pure forest, its biodiversity is definitely much simpler than that of the natural ecosystem, but it is not to the extent that "no grass grows on the ground". . One of the reasons for these criticisms is the lack of understanding of the characteristics of eucalyptus trees. It is unscientific planting methods that really cause ecological damage.
