Because when someone talks about business, there is no difference.
Analysis:
It is said that watermelon is native to the tropical arid area of sub-Saharan Africa. Its direct wild ancestor can't be found now, but there is still a large area of wild watermelon growing in Sudan, Africa.
Around the first century BC, watermelons spread from land to ancient Persia and the Western Regions (Xinjiang, China) through the Silk Road.
"History of Han Geography" records: "Dunhuang, the capital of the city, Du Lin, thought that ancient Guazhou was beautiful. The teacher said that there was a surname Rong in ancient times, which was handed down from the left in the Spring and Autumn Period and lived in Guazhou. The ground is still a big melon, and the fox can't eat it in the melon. " Later generations attached the story of Zhang Qian's mission to the Western Regions, and it was said that Zhang Qian (? -Former 1 14) Emperor Wu of the Han Dynasty ordered him to go to the Western Regions, passing through Jiayuguan, and arrived at a seriously ill place. After listening to the doctor's advice, just eat watermelon. To commemorate this place, it was named "Guazhou". Mr. Chang Zheng believes that the so-called Guazhou Rong in ancient times is not the division between the north and the south of Qinling Mountains, but the right and wrong of Dunhuang in Du Jie. See the article "On Chang 'an Guazhou and Jiang Rong Luhun" in the second volume of Beijing World Garden. ) The above information shows that as early as 2000 years ago, China, Dunhuang, Xinjiang and other places were famous for their "beautiful melons".
Watermelon can be widely planted among the people in the Central Plains, starting from the Five Dynasties of Qidan State (AD 916-1115). Then from the north to the Song Dynasty, to the Southern Song Dynasty (A.D. 1 127- 1273), it was already "eating watermelons everywhere every year". (See the poem "Watermelon Garden" by Fan Chengda, a poet in the Southern Song Dynasty: "Watermelon was originally planted in Beiyan, but now it is planted in Henan (south of the Yellow River)". There are special descriptions of watermelons in Song, Yuan, Ming and Qing Dynasties. For example, in Song Gaozong (A.D.111130), Jian Lu described the shape, color and function of watermelon in detail in his Notes on Song and Mo: "Watermelon is flat and round in shape, extremely green in color, and turns yellow when it gets old. Fang Fei in the Yuan Dynasty is even more vivid in his poem Eat Watermelon, leaving a famous sentence: "Plumes of flowers are dyed green, Dan's blood is red on the skin, the fragrance is floating and smiling, the teeth are moist and the clothes are cool." The chapter on melons and vegetables in Xuepu Miscellaneous Vegetables in Ming Dynasty, after detailed comparison with other melons, is called "the first beauty among melons". Li Shizhen recorded the cultivation, quality and medicinal value of watermelon in Compendium of Materia Medica. " Sowing in February ... It's ripe in July and August. When it's white, it tastes bad, sweet and sour, and sour is the next one. " ... and southern melons are not as good as (northern watermelons). "
It can be seen that watermelon has been planted in China for at least 2000 years. Since it was first planted in northern China, it has a history of 1000 years.
Do you know the origin of tomatoes?
Tomatoes are native to Peruvian forests and are called "wolf peaches". Because they are gorgeous and charming, people suspect that they are poisonous. They only looked at them and dared not eat them. /kloc-In the 6th century, it was brought back to Europe by an English duke, and it is still only for viewing.

1around the middle of July, 983, pottery was unearthed in the ancient tomb of the Western Han Dynasty excavated in Fenghuang Mountain in the northern suburb of Chengdu.
Nearly 60 pieces of lacquerware, rattan barnyard grass and bamboo barnyard grass were found, and food remains such as rice grains, fruits and animal bones were found. rice grain
Barnyard grass attached to bamboo, in order to maintain a certain humidity, the digger covered the rattan and bamboo with a cover.
A piece of wet cloth, together with it, was transported to the warehouse of the Cultural Relics Protection Institute for preservation. Strange things happened, ten.
Many days later, it was found that bamboo barnyard grass had plant buds inside and outside, which was very interesting.
Outside. In order to find out the details of this plant, archaeologists invited Sichuan Academy of Agricultural Sciences and China Academy of Sciences.
Experts from Chengdu Branch came to study, and the experts couldn't reach a conclusion at that time, so they decided.
Decided to take the germinated seeds back to culture, and at the same time, the cultural management office left more than a dozen plants for further observation.
Vegetable experts from Chengdu Academy of Agricultural Sciences divided the transferred germinated seeds into four pots and cultivated them in the greenhouse, and seven pots.
A few months later, on February 24th, 1984, all the plants bloomed, bore fruit and harvested on the same day.
34 fruits were obtained, which were in the shape of small red eggs and identified as tomatoes! Later, put the seeds of the results
Cultivation continued in the open field. In the first ten days of 1985+ 1, three small tomatoes matured, followed by researchers.

Scientists and vegetable experts have opened up a new way of thinking. They started working in Yunnan, Sichuan and Guangxi.
Looking for the descendants of the distant ancestors of China tomatoes in mountainous areas, we found several tomatoes that were more primitive than those in the Western Han Dynasty.
Shanxi Academy of Agricultural Sciences "small sour fruit" (also in Jiuzhaigou area)
Experts especially use wild tomatoes found in Guangxi for large-scale cultivation.
The discovery of tomatoes in the Western Han Dynasty not only added new content to the history of vegetable cultivation in China, but also told the world.
