Is Vince An poisonous?

Fast-growing eucalyptus is one of the three famous fast-growing tree species in the world and one of the most precious hardwoods in the world. Planting eucalyptus in a large area is very harmful, which will lead to land desertification, fertility decline and inhibit local protozoa. The representative meeting in Shenzhen submitted a proposal calling for banning eucalyptus planting. \x0d\ Among the people, fast-growing eucalyptus has the notoriety of "water pump", "fertilizer pump" and even "poisonous tree species". \x0d\ Chang Qunqun, deputy dean of the School of Life Sciences of Yunnan University, said in an interview with the media that the drought was first caused by the overall environment of the earth. As for the influence of eucalyptus, it is mainly the underground part of its area. Underground soil may be relatively dry, and its water-holding capacity is also weak. In this case, the drought may be aggravated under site conditions. \x0d\ Xie, Chairman of Eucalyptus Professional Committee of China Forestry Society, said in an interview with People's Daily that southwest China is a transitional intersection affected by various monsoon circulation, with distinct dry and wet seasons. Forests in this area only play a fine-tuning and buffering role in climate change. The rumor that eucalyptus causes drought in southwest China simply cannot be established. \x0d\ Comprehensive evaluation \x0d\ Some problems and defects existing in the development of eucalyptus should be treated objectively and rationally, analyzed scientifically and solved step by step. If eucalyptus is planted in water source forest and agricultural land, it is not the fault of eucalyptus itself, but the afforestation owner has not done it according to the national policy requirements. In some places, eucalyptus is planted on the hillside above 35 degrees, and eucalyptus is cut down in a large area. These wrong practices can also be changed through strict afforestation regulations. He also said that there were no birds in the sky and no grass on the ground. That is, water pumps, fertilizer suction machines, polluted water sources, etc. They don't know the situation, they just hear it through hearsay. Some also require eucalyptus not only to provide abundant wood, but also to maintain and improve plant diversity, which is too high for eucalyptus. So far, through scientific argumentation, there is not a shortcoming of eucalyptus that people can't accept. \x0d\ In short, the development of eucalyptus should be viewed scientifically and evaluated objectively. We should not only affirm the great contribution made by eucalyptus, but also clearly understand the existing shortcomings and seriously study and solve them. On October 7th, 2065438+0165438/KLOC-0, Secretary Peng Qinghua made an important speech after listening to the forestry work report, which pointed out that "in recent years, we must first affirm the contribution of eucalyptus in afforestation. Guangxi ranks first in greening and timber production in China, mainly relying on fast-growing forests, among which eucalyptus is one of the main varieties and has made contributions. At the same time, it is necessary to gradually adjust the tree species structure according to the actual needs, so as to diversify the eucalyptus and stand structure. Don't deny that this kind of eucalyptus grows eucalyptus. "
