Zhang Juan, a meteorological analyst at China weather.com, said that after October, cold air is frequent and the intensity begins to strengthen. Therefore, the temperature in some places in the north, such as northeast China and Inner Mongolia, has gradually dropped to the standard of Ginkgo discoloration, while it may have to wait until November for ginkgo discoloration in the south of the Yangtze River.
If the autumn wind gives autumn color, then ginkgo is one of the most gorgeous, full of golden yellow, rendering autumn to the extreme! China Weather Network has selected domestic ginkgo viewing places, Dandong, Liaoning, Diaoyutai, Beijing, ancient Guanyin Temple in Xi'an, Shaanxi, Yaozhuang village, Pizhou, Jiangsu, Changxing, Huzhou, Zhejiang, tongziao, Yongzhou, Hunan, Luoyang Town, Suizhou, Hubei, Tengchong, Yunnan, Haiyang Township, Guilin, Guangxi, and pingtian Town, Nanxiong, Guangdong. These places are excellent for appreciating ginkgo. Please make an appointment with TA to freeze the beautiful scenery.
In addition, in recent years, colleges and universities such as Sichuan University, University of Electronic Science and technology, Yunnan University, Liaoning University, Tsinghua University, Suzhou University, Fudan University, Nanjing University, Lanzhou University of technology, Tianjin University, Wuhan University and Xi'an Jiaotong University have become the "online red card punching place" of Ginkgo biloba. The unique vitality and academic atmosphere of the campus are perfectly integrated with Ginkgo biloba to form a beautiful autumn picture.
Note: due to different factors such as tree age and soil, the golden degree, yellowing time and duration of Ginkgo leaves in different sections of the same area are different.
The forecast of Ginkgo biloba in Dandong, Liaoning Province in 2019 is released, and the best viewing period will be entered on October 31
Dandong is one of the earliest areas in China to enter the best viewing period of Ginkgo biloba. It is also the city with the most ginkgo trees over 100 years old in the main urban area, and the viewing scale is also large. According to the situation in recent ten years, the best viewing period of Ginkgo biloba leaves in Dandong lasts about 15 days.
However, this year, Dandong has little rainfall and the average temperature continues to be high. The highest temperature on October 3 also set a new historical record. The low precipitation and high temperature led to the delayed yellowing of Ginkgo biloba this year (the best viewing period is around October 20 all year round).
It is expected that ginkgo leaves with a tree age of more than 10 years in the main streets of Dandong City will accelerate their color change from October 24 this year. From October 25 to 30, you can see the scenery of the "yellow and green corridor". From October 31 to November 5, ginkgo completely turns yellow, and the yellow leaves on and under the trees complement each other. The streets seem to become three-dimensional "Golden Avenue", which is the best time to watch Ginkgo.
Around November 10, with the continuous decline of temperature and the effect of wind, ginkgo leaves fell one after another and covered the ground, forming a 'golden carpet' scenery. Experts from the ecological and Agrometeorological center of Dandong Meteorological Bureau said that when more than 40-50% of the leaves fall off, the best viewing period of Ginkgo ends.
Ginkgo turning yellow temperature is the 'dominant' factor
The effect on the yellowing of Ginkgo biloba and the length of viewing period needs the 'cooperation' of weather, in which the temperature plays a vital role. Zhang Juan said that generally, ginkgo leaves begin to turn yellow after 1-2 rounds of cold air process with strong average temperature. Taking Huzhou, Zhejiang Province as an example, when the lowest air temperature drops below 6 ℃, ginkgo will change color and gradually enter the best viewing period.
In addition, weather factors such as rain, snow and strong wind will directly affect the duration of Ginkgo landscape. For example, strong winds of force 5 ~ 6, strong rain and snow will accelerate the falling of leaves, the leaves will gradually wither, the ground is paved with 'golden yellow', and the viewing period of ginkgo is coming to an end.
