, mountain air sinking in the leeward slope becomes a hot and dry local wind. Wind up burning a strong, can scorch the leaves of trees, land cracking, resulting in severe drought. It is often so dry fruits and crops, reducing yields.

reason to explore

saying a “foehn” incoming?

see photos of Ginkgo biloba brown, forest pest control and quarantine station of Chengdu’s deputy chief, said Li Hui, see: “is not contaminated by hazardous chemicals, this is not very good about But look at photos, this phenomenon has not only Zipingpu, Chengdu, Pi, Qionglai, Dujiangyan other places have. “

” Ginkgo from the edge of the beginning to turn yellow, curl, slowly spread throughout the leaves, and yellow fall. “See Hui Lee said that from July this year, and more a reflection of a similar situation, quarantine station also yellow Ginkgo biloba special collection of samples, laboratory back. The researchers found that the bacteria do not cause the leaves yellow on the reason. Basically ruled out pests, Li-hui that could see the “foehn” relevant.

“popular terms, ‘foehn’ is actually a hot air for a long time to dry, hot wind blades for self-protection, the loss of water to avoid root, Ginkgo leaf water loss from the edge of yellow. “See Hui Lee said, Ginkgo biloba lock water is not strong, so the” foehn “more sensitive.

claim 2 chemical destruction?

Technology Branch of the Botanical Garden in Chengdu, but Wang Ying, there is another view: “The weather is too dry may be the cause, but too much rain may also lead to this situation. At the same time, If the external environment pollution, the possibility is relatively high. “Wang Ying said, no research, it is difficult to determine.

why a few kilometers or even tens of kilometers away will have a similar phenomenon? The expert said: “Although the chemical gas can drift downwind, may be affected, but it does not categorically a conclusion.”
