"Who is this old gentleman?"
Song Yingxing asked suspiciously when he heard someone making a sound.
"President Song, this is Mr. Xu Guangqi. Your Majesty has just established the Daming Firearms Research Institute. Mr. Xu is the first director of the Firearms Research Institute."
"This is Mr. Sun Yuanhua, an expert in artillery. He is now the director of the Artillery Department of the Right Supervisor of the Firearms Research Institute. He is also a disciple of Dean Xu!"
"This is Lord Bi Maokangbi, an expert in firearms. He is currently the director of the Firearms Department of the Left Supervisor of the Firearms Research Institute."
Sun Chengzong stepped forward to introduce, and then explained the responsibilities and work of the Firearms Research Institute.
Song Yingxing listened with great interest. He was not only interested in agriculture, but also in handicrafts, firearms, etc.
Sun Chengzong continued: "Dean Song, Dean Xu is well versed in Chinese and Western studies, integrating etiquette, mathematics, military and agriculture. If he has doubts about your initiative, please answer it!"
"Student has met sir!"
To everyone's surprise, Song Yingxing gave Xu Guangqi a discipleship ceremony.
Without waiting for anyone to ask, Song Yingxing said: "The student has read Dean Xu's "Bei Geng Lu", "Yi Reclamation Order", "Agricultural Relics Miscellaneous", "Sweet Potato", "Agricultural Book Draft", "Taixi Water Law", etc. ,
In particular, students benefited a lot from the diagrams of various utensils in "Taixi Water Method". "
Everyone suddenly realized that if this was the case, it would make sense to bow as a disciple.
A trace of thought flashed in Chongzhen's eyes.
According to historical records, Xu Guangqi was summoned back in the first year of Chongzhen. The first draft of "The Complete Book of Agriculture" was published in the first year of Chongzhen. It was printed and published in 1639.
Song Yingxing was elected magistrate of Tongxiang County, Zhejiang Province by the Ministry of Civil Affairs in 1631, and the famous "Tiangong Kaiwu" was published in 1637.
If you follow what Song Yingxing said and read Xu Guangqi's book, was Tian Gongkaiwu influenced by Xu Guangqi?
"Dean Xu, please tell us, students will tell you everything they know!"
Xu Guangqi pinched the soil on his hand, looked around, and said to a sergeant: "Excuse me, little brother, help me dig down. Stop when I say."
The sergeant took the shovel and dug in. After digging seven or eight times, a pit one foot deep appeared.
"That's it!"
After Xu Guangqi finished speaking, he reached out and grabbed a handful of excavated soil, and squeezed it hard.
"Dean Song, greenhouses can solve the temperature problem on the surface, but what about underground?
It's severe winter now, and you can see that the entire foot underground is frozen solid, and the temperature is extremely low.
If after the beginning of spring, the temperature rises, the ground surface thaws, and the icy water becomes clear,
It ranges from reduced potato production to severe freeze-killed vines and no harvest. I wonder how you can solve this problem? "
After Xu Guangqi finished speaking, everyone's expressions changed. They had just ignored the underground because of the strangeness of the greenhouse.
If it cannot be solved underground, then it means that we are focusing on the beginning rather than the end, and there will be no way to talk about a greenhouse.
Song Yingxing looked at Xu Guangqi: "Dean Xu is here to teach juniors."
"If you can't plant it if it's frozen underground, then we'll plant it on the ground."
Everyone was confused. Potatoes are grown underground. How can they be grown on the ground?
"A half-meter-high dragon is formed on the surface of the earth. All the soil used to make the dragon is dried in the sun. Wheat straw is placed at the bottom to block the upward flow of underground water. Cow dung is placed in the middle, and chaff is placed on the upper layer. Then half a meter of soil is made.
Potatoes are planted here. As long as the temperature in the greenhouse is enough, watering on the roof will not freeze. This will ensure that the potatoes will not freeze to death. "
"good idea!"
Sun Chengzong clapped his hands and said, "But what are you doing with this cow dung?"
"Mr. Ge, cow dung is a high-heat substance. After being buried, it will slowly rot and generate heat to ensure that the bottom will not freeze.
Secondly, to provide fertility for potatoes, a layer of bran skin prevents the roots from directly contacting cow dung to prevent excessive fertility. "
"Good, good... very clever idea!"
Xu Guangqi also praised: "No wonder His Majesty appointed you to be the dean of the Agricultural Research Institute. This idea alone is enough for you."
"President Xu has given you the award. The predecessors planted trees for future generations to enjoy, but the younger generations are just applying what they have learned.
There are several other methods besides this, but they are too troublesome.
As long as this is harvested and the crops are flattened, the entire ground will become fertile again. "
"I'm also very interested in agriculture. Let's communicate more when we have time!"
"Haha, Song Aiqing and Xu Aiqing have almost finished the first draft of "The Complete Book of Agricultural Affairs".
If you talk more with Xu Aiqing, and through practice, you might be able to publish a book that will have an impact on the world just like the "Mengxi Bi Tan" that fascinates you. "
Chongzhen took over the words and said, Song Yingxing was full of surprise after hearing this: "This junior can only ask for it!"
Xu Guangqi was shocked. There were some people who knew about the compilation of the Complete Book of Agricultural Affairs, but he had never told anyone that the first draft had been completed. How did the emperor know about it?
"Xu Aiqing, I know you are revising the almanac. The almanac is related to farming, production, etc., and is extremely important to the people.
But your "Agricultural Policy Encyclopedia" is more important. Together with the Agricultural Research Institute, it is a perfect match.
I hope you can focus on the "Encyclopedia of Agricultural Affairs" first, and let Li Zhizao and others take charge of the almanac. You can be the editor-in-chief. What do you think? "
"I obey the decree!"
Xu Guangqi agreed without any hesitation. The emperor was trying to wake him up.
I have been an official for decades and have experienced countless ups and downs. If you can't even hear this, then you are in vain.
"Song Aiqing, please show me how to grow potatoes."
"I obey the decree!"
Song Yingxing asked someone to bring out a small basket of potatoes from a house on one side: "Your Majesty, potato planting requires several steps, such as potato selection, cutting, germination, plowing and application of base fertilizer, planting in separate holes, and top dressing for seedling emergence."
After that, he explained the steps to everyone. It took a full quarter of an hour to plant a small piece of potato.
Everyone exclaimed that it opened their eyes.
Chongzhen also nodded secretly. Although it was not as good as later generations, it was not bad after the exploration of royal vegetable farmers.
"Song Aiqing, I think that when you cut potatoes, you should pass the knife in clean water every time you cut.
Then dip the cut potatoes in plant ashes. You can experiment by yourself as to why. "
Everyone was startled again and secretly glanced at Chongzhen, full of doubts in their hearts. Does the emperor still know how to farm?
It's so unscientific. You can read books about military training, commerce, and firearms, but shouldn't you practice agriculture?
"Okay, let's take a look. It's almost lunch time. I'll invite you to play skewers today."
Chongzhen turned back to look at Wang Chengen, who immediately said: "Your Majesty, you are ready and can start at any time."
"Let's go!"
Under Wang Chengen's guidance, everyone arrived at the foot of the mountain.
On a large piece of exposed rock, there was charcoal placed in a strange object, and pieces of dressed chicken wings were placed on it. Several royal chefs turned it over from time to time and sprinkled some seasonings on it.
In the faint green smoke, a peculiar burnt and burnt aroma floated into the air.
Song Yingxing stepped forward to look at the stove and suddenly made a sound.
"Is this Shanglin Fanglu?"
