It is widely planted in the north and south of China, especially in Wuhan and Hangzhou. Lotus is one of the earliest species and genera of angiosperms. According to the study of fossils by paleobotanists, lotus was distributed in many waters in the northern hemisphere10.35 billion years ago.

It grew on the earth much earlier than the appearance of human ancestors (2 million years ago). Lotus is an ancient plant before the Ice Age, which ranks with Metasequoia glyptostroboides, Ginkgo biloba, Liriodendron chinense of China and Sequoia sempervirens. , is the representative of the residual plants that survived the ice age.

According to different cultivation purposes, it can be divided into lotus root, lotus seed and Hualien. Lotus is called lotus root, which mainly produces lotus root, and this kind of variety has few flowers; Purple lotus, which mainly produces lotus seeds, has dense flowers, but its ornamental value is not as good as that of Hualien. Hualien, which is mainly ornamental, is mostly bubble-shaped or petal-shaped, and often cannot bear fruit.

Lianxi enjoys relatively stable still water and avoids running water with great fluctuation and wind and waves. In general, the water depth should not exceed1.5m. The optimum temperature of stems and leaves in the growing season is 25~30℃.

It needs plenty of sunshine, so it is not suitable for long-term indoor cultivation. Clay loam rich in organic matter is suitable for soil quality.

Lotus seeds have a very long life span, and thousands of years old lotus seeds can sprout new plants. Lotus is often propagated by ramets or by sowing.

Lotus root It is one of the earliest species of angiosperms. According to the fossils studied by paleobotanists, lotus plants were distributed in many waters in the northern hemisphere10.35 billion years ago.

At that time, it was in the late stage of the rapid decline of the giant reptile dinosaur, and its growth time on the earth was much earlier than the appearance of human ancestors (2 million years ago). According to Paleobotany (1965) by A.H. Christophevich of the former Soviet Union, lotus fossils have been found in Cretaceous strata in the Arctic of North America and amur river Basin of Asia (i.e. Heilongjiang), as well as Oligocene and Miocene strata in Europe and East Asia (Sakhalin Island) and Japan.

At that time, the temperature on the earth was warmer than it is now. There were about 10~ 12 species of lotus plants distributed in five continents. With the advent of the post-glacial period, the global temperature dropped, making many plants extinct, while others were forced to drift away, completely breaking the original geographical distribution.

Because of this disaster, two varieties of lotus survived, and their distribution range narrowed. Chinese lotus (Nelumbo nucifera) is distributed in Asia and northern Oceania, and N.lutea drifts to North America. Paleobotanists also pointed out that the lotus fossils from Pleistocene to Holocene (2 million years ago) excavated in Hokkaido and Kyoto are similar to modern China lotus; The lotus leaf fossils unearthed in Qaidam Basin, China, 6.5438+million years ago are similar to modern China lotus.

In 1970s, China Institute of Petroleum Exploration and Development Planning, Ministry of Petrochemical Industry and Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences recorded in the book "Early Tertiary Sporopollen in Coastal Areas of Bohai Sea" that two kinds of lotus pollen fossils were found in Panshan, Liaoning, Beidagang, Tianjin, Kenli, Guangrao, Shandong and Cangzhou, Hebei. Fossils of the genus Nelumbo were also found in the strata of Changchang Basin in Qiongshan, Hainan Island, China, in the Tertiary tropical phytogeographical region.

At present, the original wild lotus is still distributed in lakes and swamps in Fuyuan, Hulin, Tongjiang and Shangzhi counties of Heilongjiang Province. The above shows that lotus is an ancient plant before the ice age, and it belongs to the representative of relict plant that was not swallowed by the ice age glaciers, such as Paeonia suffruticosa, Ginkgo biloba, Liriodendron chinense, Sequoia sempervirens and so on.

[Edit this paragraph] Hualien-innocent. Muddy but not dirty, clear but not demon, straight through, not crawling, indicating firmness and purity. Another way of saying it: the flower language of lotus is faith.

Anthers are long, filaments are slender and inserted under receptacle; The style is very short, and the top of the column is born; The receptacle (lotus house) is 5- 10 cm in diameter.

Second, growing habits

Lotus is an aquatic plant, which likes relatively stable and calm shallow water, lakes, swamps and ponds, and is its suitable habitat. The water demand of lotus depends on the variety. The relative water level of large plant-shaped varieties such as Gulian and Chiba is deep, but it cannot exceed 1.7 meters.

Small and medium-sized plants are only suitable for water depth of 20-60 cm. Meanwhile, lotus is very sensitive to water loss. In summer, as long as there is no irrigation for 3 hours, the lotus leaves planted in the water tank will be sluggish. If the water is stopped for one day, the lotus leaves will be burnt and the buds will wither. Lotus is also very fond of light, and it needs full light environment during its growing period. Lotus is extremely intolerant of shade, so it will show strong phototaxis when it grows in semi-shade.

7. Lotus knowledge

Lotus is a perennial aquatic plant.

Rootstock (lotus root) is thick and knobby, born in sediment. The leaves are shield-shaped, round, dark green on the surface, gray-green with waxy white powder on the back, and undulate all over.

Petiole cylindrical, densely barbed. Flowers are solitary at the top of pedicels and above the water surface, with single petals, compound petals, double petals and double petals.

There are many cultivated varieties of lotus, which can be divided into three systems according to different uses: lotus root, lotus seed and Hualien. Lotus originated in China, from Viet Nam to Afghanistan, and generally distributed in subtropical and temperate regions such as Central Asia, West Asia, North America, India, China and Japan.

China was cultivated as early as 3000 years ago. Now carbonized ancient lotus seeds have been found in Liaoning and Zhejiang, which shows its long history. Taiwan Province Province was introduced from Japan only 100 years ago. At present, the cultivated area in Baihe Town and Chiayi in Tainan has reached nearly 350 hectares, which is one of the most important tourist areas in Taiwan Province Province.

There are still wild lotus flowers in some remote places in Asia, but most of them are planted artificially for landscape decoration and eating. For example, in China, lotus is cultivated as a cash crop. Many people once mistakenly thought that lotus was produced in Egypt and the Mediterranean.

Around 500 BC, lotus was introduced into Egypt, probably brought by Persians. The ancient Egyptians decorated "lotus buds" on the top of the pillars of the temple, imitating water lilies, while Homer's epic "Odyssey" actually drank a drink made of dates (unrelated to lotus flowers) and entered a state of forgetting troubles.

Herodotus, a Greek writer, wrote when describing Egyptian plants: "There are some lilies like roses growing in the river, and the fruits grow in pods like yellow honeycombs. There are many fruits the size of olive stones to eat, fresh or dry. "

What he said was clearly a lotus flower. Lotus, one of the top ten famous flowers in China, is not only colorful and fragrant, but also has strong adaptability. It can be widely planted in lakes, which is spectacular and can be potted in bottles. Since ancient times, precious aquatic flowers in palace gardens and private gardens have been favored by people more and more, and are widely used in modern landscape gardens.

Lotus is called "living fossil" and is one of the earliest plants in angiosperms. Before humans appeared, about 104500 years ago, most of the earth was covered by oceans, lakes and swamps.

At that time, the climate was bad, disasters were frequent, there were no animals, most plants were eliminated, and only a few wild plants with strong vitality grew on this barren land. Among them, there is an aquatic plant that we call "Lotus" today, which has withstood the test of nature and stubbornly survived in amur river (now Heilongjiang), the Yellow River, the Yangtze River basin and the swamp lakes in the northern hemisphere.

About 9,000 years later, primitive humans began to appear. In order to survive, human beings collect wild fruits to satisfy their hunger, and soon find that the wild fruits and root nodes of this "lotus" (namely lotus seeds and lotus roots) are not only edible, but also sweet and delicious.

Gradually, "Lotus", a food source for human survival, was deeply imprinted in the hearts of our ancestors, primitive humans, and became a symbol of human survival. Named after its shape: Lotus: Li Shizhen's Compendium of Materia Medica explains: "Lotus stems carry leaves and leaves carry flowers, hence the name."

Hibiscus: Also known as Hibiscus. The Chinese dictionary Erya explains: "Lotus contains Pupu."

Another book, Shuo Wen Jie Zi, said, "It's not lotus, it's hibiscus." Li Shizhen also said that the hibiscus flower means "to dress up brilliantly", so it is no wonder that Sima Xiangru, a writer in the Han Dynasty, compared his wife Zhuo Wenjun to the hibiscus flower of water.

2. Named after their growth habits: Shuizhi, Huashui, Yunshui, Shuidan, Shui Mu and Zezhi: Because lotus is a perennial aquatic plant, the ancients classified it as an aquatic plant, and most of them were named after the word "water". Cao Zhi, a litterateur of the Three Kingdoms, praised "a hundred flowers blossom, and there is no flower soul" in the Lotus Fu, and compared the lotus to Ganoderma lucidum in the water.

3. Named after the holy and elegant temperament of lotus: Junzihua, Ling Boxian, Shuigongxian, Yuhuan, etc. According to "The Tale of the North Dream", Su Changyuan lived in Wuzhong (present-day Suzhou) during Tang Chaoyuan and his reign (806~820), and met a pink-faced girl from plain clothes and gave him a jade ring. Soon, he found a lotus flower in the pool of his yard, and a jade ring in the pistil, but it was "absolutely broken" and later generations called it the jade ring.

4. In the ancient Jiangnan custom, June 24th of the lunar calendar was the birthday of the lotus, so the lotus was nicknamed "June Flower God". 5. It is called "the gentleman in the flower" because it is "out of the mud but not stained".

The most famous is "Lotus Out of the Water" by Wu Bing of the Southern Song Dynasty Painting Academy, which vividly and delicately depicts the fresh and refined style of lotus. There is also the "Lotus Yuanyang Map" by the painter Zhang Zizheng in the late Ming Dynasty; Chen Qing painted lotus flowers; Lotus and mandarin ducks in Ren Bonian in Qing Dynasty: Lotus and Flowers and Birds by Xie in the Republic of China; Ma Song Xingzu's "Dredging Birds"; Song Fan painted "Late Lotus Fruit Suotu"; Song people painted "Lotus Crab Map"; Song Feng has a picture of Taiyue Lotus Wind; Inheriting the Song people's "Children and grandchildren together".

8. Some knowledge about lotus.

1, Chinese name: Lotus, lotus scientific name: Lotus (English name: Lotus) Alias: Lotus, Lotus, Shuizhi, Zezhi, Blooming Lotus, Shuidan, Grass Hibiscus, Water Hibiscus, Yuhuan, June Spring, Hindu Lotus, Six.

China was cultivated as early as 3,000 years ago, and now carbonized ancient lotus seeds are found in Liaoning, Zhejiang and other places, which shows its long history. Taiwan Province Province was introduced from Japan only 100 years ago. At present, the cultivated area in Baihe Town and Chiayi in Tainan has reached nearly 350 hectares, which is one of the most important tourist areas in Taiwan Province Province.

There are still wild lotus flowers in some remote places in Asia, but most of them are planted artificially for landscape decoration and eating. For example, in China, lotus is cultivated as a cash crop. Many people once mistakenly thought that lotus was produced in Egypt and the Mediterranean.

Around 500 BC, lotus was introduced into Egypt, probably brought by Persians.

Herodotus, a Greek writer, wrote when describing Egyptian plants: "There are some lilies like roses growing in the river, and the fruits grow in pods like yellow honeycombs. There are many fruits the size of olive stones to eat, fresh or dry. "

What he said was clearly a lotus flower. 3. [Study on the Mystery of Longevity of Lotus Seeds] It is often reported that ancient lotus seeds will bloom after sleeping for thousands of years, which is related to the structure of lotus seeds.

The outer seed coat of lotus seeds is hard and dense, like a small "sealed bag". Sealing the seeds inside can prevent the infiltration of external moisture and air and prevent the loss of moisture and air inside the seeds, so the life activity of lotus seeds is extremely weak, which is equivalent to being in a dormant state. This is an important reason why ancient lotus seeds still have vitality.

In addition, it will also be related to the environment where ancient lotus seeds are buried. For example, ancient lotus seeds are buried in a peat layer about 30-60 cm deep, and peat has good water absorption and moisture resistance; In addition, the peat layer is covered with thick soil, so the ancient lotus seeds are almost in a closed environment.

In such an environment, ancient lotus seeds do not have the conditions to take root and sprout, so they can preserve their vitality. 4. Variety ① Traditional cultivated varieties in Beijing.
