Lotus is generally distributed in subtropical and temperate regions of Central Asia, West Asia, North America, India, China, Japan. The lotus flower starts from Hainan Island in the south of China (about 19 degrees north latitude), Fujin in the north (47.3 degrees north latitude), Shanghai and Taiwan Province in the east, and Tianshan Mountain in the west. Except for the Tibet Autonomous Region and Qinghai Province, most of the country The area is distributed. The vertical distribution can reach 2000 meters above sea level, and can also be seen in the deep mountain ponds of Qinling and Shennongjia.
China has been cultivated for more than 3,000 years. Carbonized ancient lotus seeds have been found in Liaoning and Zhejiang, showing its long history. The Taiwan area was introduced only by Japan 100 years ago. In the Baihe Town and Chiayi area of Tainan, the area of cultivation is nearly 350 hectares. It is one of the most important sightseeing areas in Taiwan. Some remote places in Asia still have wild lotus, but most of the lotus is artificially planted.
The lotus is an aquatic plant, and the calm and shallow water, the lake, the zebra, and the pond are relatively stable. The water requirement of lotus is determined by its variety. Large plant varieties such as ancient lotus and red lotus have a relatively deep water level, but cannot exceed 1.7 meters. The medium and small plant shape is only suitable for water depths of 20-60 cm. At the same time, the lotus flower is very sensitive to water loss. If it is not watered for 3 hours in summer, the lotus leaf in the water tank will be wilted. If the water is stopped for one day, the lotus leaf will be burnt and the flower bud will return to dryness. The lotus flower is also very happy, and the environment needs a full light environment during the growth period. The lotus flower is extremely intolerant to shade and grows in the semi-shade to show strong phototaxis.
