China News Service, Hangzhou, April 7th (Jiang Yangye and Wang Pingping) In the spring of Hangzhou, Zhejiang, the flying flies in the sky sometimes rushed into the nostrils and sometimes into the neck, which annoyed people. On April 7, the reporter learned from the Landscaping Department of the Hangzhou Municipal Bureau of Landscape and Cultural Relics that after two years of follow-up tests, the Hangzhou phoenix tree (plane tree) fly floc suppression test was finally successful. Next, indus fly floc suppression work will be fully implemented in Hangzhou.

The plane tree can be described as the “king of street trees” and one of the main garden landscape trees in Hangzhou. As a tall deciduous tree, it grows fast, has strong resistance, has a large canopy, and has excellent shading effects in summer. It can quickly form a tree-lined avenue; it can create a better garden landscape in autumn; and deciduous leaves in winter are reduced to a large extent The contradiction between daylighting and greening greatly reduces the pressure of anti-snow and anti-freeze work in the garden industry in winter.

According to incomplete statistics, about 42,000 platanus plants are planted in Hangzhou. Among them, the platanus trees in the West Lake scenic area are relatively older, all over 70 years old, and they have all been included in the list of reserve ancient trees.

The sycamore blossoms and grows new leaves in mid-to-late March each year; from late March to early April, it will bear small young fruits; in September and October, the cones of the sycamore tree will mature , Is greenish-brown and will not produce fuzz; when winter comes, the sycamore trees will shed their leaves, and the round cones will still hang intact on the branches for the winter. From a distance, they look like small bells. That’s why it has the name “Platanus”.

As the temperature continues to rise in the coming spring, mature cones will be completely blown away by a gust of warm wind, forming flying flies.

Chen Liang, a staff member of the Landscaping Division of the Hangzhou Municipal Bureau of Landscape and Cultural Heritage, introduced that the inhibition test of phoenix tree flies was carried out by injection of medicine into the trunk. “This method can make plants receive more balanced drugs, and can also help plants better absorb and decompose drugs, thereby achieving a better inhibitory effect.”

From Tongpu Road and Xiacheng District, Xihu District, Hangzhou According to the results of the fly floc suppression test carried out by Platan on Jisi Road, the number of Platanus in the drug injection section has been greatly reduced, the drug injection hole has healed well, and the plant growth situation is in a good state.

Chen Liang said: “After observations, the cones of Platanus vulgaris in the test section have been reduced by more than 90%, and even the whole plant has no fruit.”

From the point of view of the test, The cost of injecting medicine for the nearly 100-year-old plane tree is only less than 50 yuan, and the smaller tree costs about 10 yuan, and the cost is controllable.

It is reported that the suppression of phoenix fly flocculent will be fully implemented in Hangzhou. (End)
