When did Luzhou umbrella industry originate?

Luzhou umbrella industry originated in the late Ming and early Qing dynasties. Especially from the late forties to the early fifties, Zhuzhu Street near the wharf in the small city of Luzhou was the oil-paper umbrella street in Luzhou at that time.

Expanding knowledge

Luzhou, a prefecture-level city under the jurisdiction of Sichuan Province, was called "Jiangyang" in ancient times, also known as Wine City and Jiangcheng, and is located in the southeast of Sichuan Province. It belongs to subtropical humid climate zone, and the three-dimensional climate in the southern mountainous area is obvious; By the end of December 222, the city had jurisdiction over 3 municipal districts and 4 counties, with an administrative area of 12,236.2 square kilometers; The total registered population is 5,38,2.

Luzhou established Jiangyang Houguo in the Western Han Dynasty; Luzhou was established in Datong, Liang Wudi; In the Song Dynasty, it was an important meeting of the southwest, and in the Ming Dynasty, it stood in a tripartite confrontation with Chengdu and Chongqing, becoming one of the 33 commercial metropolises in China at that time.

Topography

The basic outline of the surface topography of Luzhou City is dominated by low mountains and Zhongshan landforms, and it is a typical mountainous city with a mountainous area accounting for 56.14% of the total land area.

the Yangtze river valley in the middle is the lowest center, and it gradually rises to the north and south banks. The lowest elevation of the Yangtze River Valley is 23 meters (on the river surface of Guan Qiao Village in Lujiao Village, Hejiang), which is the center where the geomorphologic erosion datum level and the runoff on the north and south banks converge in Luzhou area. The highest on the north shore is Wanshou Mountain, with an altitude of 757.7 meters. The highest on the south bank is Luohanlin in Xuyong, with an altitude of 192 meters.

The north and south banks are asymmetrical saddle-shaped, with a height difference of over 1, meters. In addition, the similarities and differences between the geomorphological contours of the north and south banks lie in the fact that the Yunnan-Guizhou Plateau is in the south, mainly in the low and Zhongshan mountains, with dense mountains and little flat land; And the height gradually rises to 192 meters. The north bank is a gentle sloping plain in Sichuan Basin. Except for some low mountains such as Baodaoling, Gufo Mountain and Longguan Mountain, most of them are gentle hills and wide valleys. And the height increase rate is small, showing a landscape of flat fields and fields.

climate

Luzhou is a subtropical humid climate zone, and the three-dimensional climate in the southern mountainous area is obvious. The temperature is high, the sunshine is abundant, the rainfall is abundant, the four seasons are distinct, the frost-free period is long, the temperature, light and water are in the same season, the monsoon climate is obvious, the spring and autumn are warm, the summer is hot and the winter is not too cold. However, affected by the topography of Sichuan Basin, Luzhou City has many thunderstorms in summer, rainy weather and foggy weather in winter, but there are few strong winds all year round, mostly -2 m/s breeze.

in p>216, the temperature in Luzhou was higher, the precipitation was more, the sunshine was slightly more normal, and the light, temperature and water were sufficient throughout the year, which was a normal preference year for agrometeorological years. During the year, meteorological disasters such as high temperature, drought, continuous rain, wind hail and thunderstorm were lighter than normal; The frequency and intensity of strong cooling process are basically the same as normal; Heavy rains and floods occur frequently.
