On the second floor of Wangyue Tower, following Liu Jin's explanation, people from the south and the north all stood up and spoke about the climate conditions in their hometowns. As soon as everyone spoke, they immediately understood exactly what Liu Jin said and the explanation made perfect sense.
Liu Jin looked at everyone and said "you, me", he also smiled and took a short rest.
"I understand why the rice here in Luzon can be harvested three times a year. Because it is in the equatorial region, it is summer all year round, and it is warm enough, so it can be harvested three times a year."
"In our Ming Dynasty, the further north we go, the cooler the temperature becomes. When we reach the Qinling Mountains and the Huaihe River line, although we can still grow rice, it can only be harvested once a year, while in the Jiangnan area, we can have two crops a year.
If you go north, because the temperature is not enough, you can't grow rice at all, you can only grow wheat."
Lin Shuhong seemed to have figured out something and couldn't help but say it excitedly.
"Well, that's right."
Liu Jin nodded and said.
"Actually, our agriculture and geographical location are also closely related."
"The south is not only warmer, but also has more rainfall, so we can grow rice. The north is colder and has less rainfall, so we can only grow wheat."
"Have you noticed that the further south you go, the denser the trees on the mountains become? And once you get to southern Jiangxi, Guangdong, Guangxi, and Fujian, the trees will not lose their leaves in winter."
"Trees in the north will lose their leaves, and there are much fewer forests in the north than in the south. This is all related to precipitation. After passing the Great Wall, we entered the Tatar and Oara regions. These regions are not only cold, but also have less precipitation.
Therefore, the vegetation in these places is mainly grassland and there are not many forests."
"Our precipitation basically comes from the ocean. The continent where our Ming Dynasty is located is very huge. The closer to the ocean, the more precipitation there is. The further away, the less precipitation."
"That's why we have our fertile Ming Dynasty. Going north and west, these places are deserts and grasslands, because there is too little water from the ocean."
Then Liu Jin continued to talk about precipitation. A long line was drawn in the Ming Dynasty area, which is also the well-known precipitation dividing line and the dividing line between east and west.
"It turns out that's the case. It's no wonder our Shaanxi province has so little precipitation. This is because we are too far away from the sea."
Someone from the northwest nodded and said.
"The distinction between north and south is actually related to precipitation."
Someone said in sudden enlightenment after hearing this.
"In fact, where Daming is located, precipitation in the north and south is very regular. The precipitation in Daming is a typical monsoon season. The so-called monsoon season is closely related to the monsoon."
"Generally, the precipitation in our next year will start from the south, starting from Guangdong and Guangxi at the earliest. They usually start to rain in March and April."
"Then the monsoon will start to move northward, and when it reaches the Yangtze River area, it will be May and June. This time we call it the plum rain season."
"If you continue to go north, it will continue to go north as time goes by. The further north you go, the later the rainy season will come. The further south you go, the earlier the rainy season will come."
Liu Jin continued to take out his writing brush and drew several horizontal lines on the map, marking the time respectively, so that people could see clearly at once.
"Yes, it rains relatively early here in Guangdong."
The man from Guangdong stood up and said.
“The same is true in the Jiangnan region~”
"It's almost exactly the same time in the north."
Everyone else also nodded.
"If this monsoon moves at the time I mentioned every year, then in that year we will have good weather in the north and south of Ming Dynasty, and it will be a good harvest year."
"However, this monsoon can sometimes be very abnormal. For example, sometimes it stays in the south for too long. In June and July, it is still in the south and has not moved north, so that year we will have a
If there is a disaster year with floods in the south and drought in the north, if it moves too fast and stays in the south for too short a time and reaches the north in May or June, then we will have a famine in the Ming Dynasty with floods in the north and drought in the south."
"Our Ming Dynasty has a special geographical location. Once a problem occurs, it is not just a problem in one place. If there is a drought in the north, there will be a flood in the south. If there is a flood in the north, there will be a drought in the south."
"It's just that because the south is close to the ocean, there is more precipitation, and there are more forests in the south, so droughts and floods have less impact on the south. But the north is different. The north is full of plains with sparse vegetation.
Once a drought or flood occurs, the situation will be very serious. Throughout the ages, disaster problems in the north have been much more serious than in the south."
Liu Jin looked at everyone and continued talking.
The Golden Continent mentioned earlier, Australia, Nanyang, etc., or even the earth, everyone thinks it is relatively far away, and they always don't believe Liu Jin's words.
Now when it comes to the distinction between north and south, the difference between north and south, and the precipitation situation between north and south, this is closely related to everyone, and what Liu Jin said is very accurate, so everyone believes in Liu Jin's words more.
"Is that so?"
"After you go back, you must carefully check the information from previous years and verify it."
When the middle-aged man heard this, his eyes lit up, as if he remembered something.
"Isn't this monsoon the Dragon King? The Dragon King is in a good mood. The weather is good in the south of Ming Dynasty. If the Dragon King is unhappy, it will be either a drought in the south or a flood in the north, or vice versa."
After listening to Liu Jin's words, some people couldn't help but smile.
"Isn't that right? It's really almost the same as the Dragon Prince."
When Liu Jin heard this, he immediately laughed. People in this era like to associate everything with ghosts and gods. As soon as he mentioned Monsoon, some people immediately said he was the Dragon King. It was really dumbfounding.
"No wonder all the problems in the past dynasties were caused by the north first. Every dynasty change must be caused by a severe drought. The Yellow Turban Uprising was caused by a severe drought and no harvest, which ultimately led to the demise of the Eastern Han Dynasty."
"The uprising at the end of the Tang Dynasty was also due to the severe drought at that time, combined with excessive taxation and excessive taxation, which caused turmoil in the world; the time of the Taizu uprising of our dynasty also happened to be a severe drought in the northern region, coupled with the corruption of officials in the Northern Yuan Dynasty, excessive taxation, and excessive levies and miscellaneous taxes, which made the people unable to live. My Taizu
Rising from the sky, this is how I came to be, the Ming Dynasty."
Huang Jinquan is familiar with history. When he heard this, he thought of the rise and fall of past dynasties. His eyes widened immediately, as if he had discovered some pattern, and he said it loudly.
