According to reports, 12 groups have more than 30 villagers, each household has more or less similar situation, but no damage to the statistics of specific data.
different voices a few kilometers away is also yellow ginkgo leaves
Wangjiang residing in the village from the 12 group 3 km outside the village Wang Shuxiang, there is another views.
“just Wangjiang village, there are other places in Dujiangyan, such Longchi, Yutang. Gas leakage can not affect it so far!” Wang Shuxiang said, the beginning of yellow ginkgo, he thought it was pests, to the village had also bought disinfectant, but pouring the syrup, the ginkgo still dry.
“Ginkgo is Wangjiang village’s pillar industries, the economic income each year tens of hundreds of million.” Wang Shuxiang said, if the situation continues to deteriorate, the villagers will suffer huge losses.

return to Chengdu on the way, West China City Daily reporter found, Yutang town there is also a similar situation, have high-speed Timor (microblogging) side, there are many signs of Ginkgo yellowing.
experts say no dead trees will sprout next year
Although the ginkgo tree can not sell this year, but Wangjiang villagers are most worried about is that next year will encounter the same situation?
this regard, the experts looked at the photos have said that at present, but leaves start turning yellow ginkgo trees, the tree is not dead.
“which leaves out, this year can continue to send the leaves, this is not to say, but next year the spring germination is more determined.” Chengdu forest pest control and quarantine, see Li Hui said Zhanfuzhanchang , the villagers can rest assured.
, 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.
Chengdu Green Management Office of the experts also expressed similar views. “The recent climate change does not seem so great.” The expert said, Zipingpu dogged leakage of hazardous chemicals, if the concentration is too large, which have an impact on the Ginkgo is very possible.
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.”
