Jiangnan recalls, the most memorable is Hangzhou. In the middle of the month, yamaji looks for Katsurako, and the county pavilion pillow looks at the tide. When to revisit.
Hangzhou has an 8,000-year history of civilization and a 5,000-year history of city building, and was listed by the State Council as one of the first batch of historical and cultural cities in China on February 8, 1982.
From July 20 to 23, 1983, on the basis of the vote of the citizens of Hangzhou, the ninth meeting of the Standing Committee of the Sixth People's Congress of Hangzhou decided that the camphor was the hangzhou city tree and the osmanthus flower was the hangzhou city flower.
Hangzhou has a long history of planting camphor, the "Fa Xiang Tang Camphor" by the West Lake, this year should be 1070 years old, in the Hangzhou area, there are written records of the camphor tree, it is the oldest. Near the Yuquan parking lot of the botanical garden, there is also a 700-year-old ancient camphor tree, and there is a tree hole in the thick tree body, which becomes a unique scenery. Hangzhou's city tree, fragrant camphor, is regarded as a village landscape tree, feng shui tree, ancestral tree in the folk, meaning longevity, auspiciousness, and people are very admired.
On August 4, 1999, with the approval of the State Council, camphor trees were included in the list of wild plants under national key protection (the first batch) and are national second-level protected plants.
Camphor is a large evergreen tree of the family Lauraceae, Camphoraceae, and is a subtropical evergreen broad-leaved tree species that prefers warm and humid climatic conditions and is not cold tolerant. It is suitable for growing in areas with an average annual temperature of 16 to 17 °C or more and an absolute low temperature of -7 °C or more. Camphor does not have strict soil requirements and develops well in deep and fertile clay loams, sandy loams, acidic and neutral soils.
The branches and leaves of the camphor are broken and emit aroma, which has a certain repellent effect on mosquitoes and insects, and there are few diseases and insect pests during the growing season, and it is also an important environmental protection tree species.
The camphor tree is majestic in shape, evergreen in all seasons, the canopy is unfolded, the branches and leaves are luxuriant, the shade is covered, the branches and leaves are beautiful and fragrant, and it is an excellent tree species as a street tree, a garden shade tree, a landscape forest, a windproof forest and a soundproof forest belt.
In recent years, the northern region has also begun to plant camphor trees, but in the northern Jiangsu region, in the winter of 2015 and 2020, the continuous low temperature lasted for more than ten days, resulting in serious frosting of camphor trees, and after the spring, the camphor trees had to be "beheaded" to be treated, most of which re-sprouted and survived, but some trees were frozen to death.
