Chen Zilong then asked: "In the harvest year, you said that there was little rain in Jingshi and Hedong, to what extent?"

Huaxue is a little cloudy, this is the original text of the record, that is, there is less rain. I had to say: "It's hard to say to what extent, let alone now, it's hard for me to accurately judge even in the summer, but it's definitely less." ”

The more Hua Xue said that she couldn't judge accurately, the more everyone felt that he was not a believer, and the more they felt that he was reliable, because most liars would speak loudly and say that they could do anything. Of course, their thinking is too simple in the information age, but in the context of the times at that time, it was not easy to make such a judgment.

Chen Zilong also nodded in his heart, in fact, there is no accurate enough record of rainfall in the books, like Hua Xue, a prediction method that relies on the data to study by itself, based on the data itself is only to use words such as "less rain" and "drought" to describe the drought, if Hua Xue can make a more accurate judgment, it is not normal. Chen Zilong asked this not to know a more precise description, but to verify whether Hua Xue was bragging.

Chen Zilong continued to ask: "In the harvest year, you said that the rain is formed because the water vapor is cold, so why is there a deterioration of rainwater?" ”

This is not difficult to pour Hua Xue, the original planet was very polluted back then, so later the interstellar era learned a lesson, and the education of environmental protection has never been relaxed, so Hua Xue does not need to check the information to know why the rain may deteriorate.

"You may not see it much, but a few of you who are in the north all year round should see dust and dust. There is not only water vapor in the air, but also dust that is swept up by the wind, and the drier it is, the heavier the dust will become. The dust raised by the storm is mixed with the condensed rainwater and falls, which causes the rainwater to deteriorate. Although I know about the more complex changes, I don't understand it for you, you just need to know that there is such a thing. ”

Hua Xue was not only annoyed by the question, but the key was that it was difficult for him to explain the reasons for the last two predictions, so he simply blocked the words and waited for the results to come out, it was clear at a glance whether it was right or not, no matter how much he explained now, it would be useless once the results were wrong.

Chen Zilong was choked again, this kid was really unfriendly to him.

The other people have no expertise in this area, so they don't understand and have no objection to Hua Xue's words, except that they feel that Hua Xue is a little crazy, and they can only look at Chen Zilong to see how he reacts.

Chen Zilong couldn't help it, so he turned to Chongzhen and replied: "Your Majesty, the five predictions made by Mr. Feng Nian this time are all easy to determine once they happen. In particular, the first prediction about hail says that it will happen in these two months. Listening to Mr. Xiao's prediction, he is not only coherent, but also able to justify himself, and his credibility is quite high. Moreover, Mr. Jr.'s conclusion does not contradict the way he said he reached the conclusion, which adds to the credibility. Chen was sure that Mr. Xiao had real talent and learning, and at least in astronomy, the student was willing to bow down. As for the accuracy of the forecast, we have to wait for specific information. ”

Chongzhen understood that Chen Zilong was convinced, but there was still confusion: "What does Qing mean by 'no contradiction'?" ”

Chen Zilong said: "Mr. Xiao's research is not based on his own field measurements over the years, but through the materials that have been circulated over the years. The records in these materials, just like the words used by Mr. Xiao before, are 'little rain', 'big drought' and so on. The minister asked Mr. Xiao before about the degree of 'lack of rain', and the more accurate conclusion is that he needs to personally measure the rain in the local area for many years, which is information that Mr. Xiao cannot obtain personally. And what Mr. Xiao said is difficult to judge, which just shows that the source of his judgment is indeed those circulating materials. ”

Hua Xue rolled her eyes on the side, this Chen Zilong was too yin, and he actually dug a pit for him. Fortunately, there are indeed those vague words in the historical record, otherwise it would be difficult to explain.

Chen Hongmi's prediction of Hua Xue is convinced, so he is more concerned about how to help the people affected by the disaster.

"You made these predictions in a good year, can you have corresponding disaster relief measures?"

Hua Xue's database is still relatively complete, but what he wrote down at the time were all historical materials, so the disaster relief measures recorded in the history books are also the responses recorded in the history books, and these countermeasures have the limitations of the times and regions, and Hua Xue doesn't know if it's good or not, so I don't plan to take it out. But there are some measures that are universal.

"The damage caused by hail is a one-time occurrence at the time of the hailstorm, and there are very few subsequent disasters. Therefore, there are two main ways to reduce the damage caused by hail. The first is to remind people to prepare bamboo baskets or wicker baskets and the like when they go out in the past two months, and protect their heads in case of hail, so as to reduce casualties. Second, the crops planted this year should be mainly sweet potatoes and the like, rather than those that will be destroyed when the hail is smashed. ”

These two measures are not recorded in historical records, the former is thought of from the helmet, and the latter is the basic understanding of tuber crops.

Chongzhen asked, "What is a sweet potato?" ”

"A crop similar to sweet potatoes, there must be one in Shaanxi, and I don't know if there is one in Shanxi. Sweet potatoes are also available. ”

Chongzhen continued to ask, "What is a sweet potato?" "How could he, an emperor who grew up in the court, have any insight into crops? What's more, both of these are newly introduced crops.

Hua Xue was helpless and said: "Sweet potatoes are also called sweet potatoes, Xu Ge always knows that there is a "Sweet Potato Shu", right?" ”

Even if Chongzhen saw it, it was impossible to remember, and turned his head to look at Chen Zilong.

Chen Zilong nodded: "Yes, indeed." Xu Shi said that sweet potatoes are suitable for promotion in most parts of the country, with high yields, drought resistance, and good taste. As for white potatoes, I don't know much about them either. ”

Hua Xue said: "You can send someone to Shaanxi to investigate the matter of white potatoes, I heard that there is planting over there, but I don't know what the people over there call it." Like sweet potatoes, they are dug out of the ground, which is rounder than sweet potatoes and has an earthy yellow skin. Like sweet potatoes, they are drought-tolerant crops. Moreover, compared with sweet potatoes, white potatoes are cold-resistant and suitable for cultivation in dry and cold areas in the northwest. ”

Chen Zilong wondered: "How do you know this?" ”

Hua Xue said: "I asked when I was eating, and I said that it was a rare thing brought from Shaanxi. ”

"And how do you know its characteristics?"

"Of course they asked together."

Chen Zilong obviously didn't believe it, even if the person who brought the thing knew where the thing came from, how could he know that the thing was drought and cold-resistant? And Hua Xue said that she didn't know what to call it in Shaanxi, and there was obviously a problem. However, since Xiaohuaxue said so, Chen Zilong knew that he would not say anything if he asked again, so he didn't ask again.

Chen Hongmi asked again: "What about the others?" ”

Hua Xue shook her head: "With this old disciple of Xu Ge here, how to fight the disaster, you don't need to ask me, right?" I really don't have any research on these specific issues! ”
