Datang Longya

Chapter 97 Nitrogen Fertilizers
In the early morning, as soon as the gate of Chang'an City opened, Liu Yuan led a tall horse and walked slowly towards Tianxia Manor.

As the minister of Sinong Temple, one of the nine ministers, Liu Yuan has not been so leisurely for four or five years.

Five days, this is a holiday approved by the emperor, Liu Yuan, who has never had such a long holiday, suddenly felt that every corner of his body was singing.

Coming out of Chang'an City, Liu Yuan would stop and take a look at the growth of the crops every time he came to a piece of farmland. This is his professional habit and cannot be changed.

Looking all the way, when he found that the sun had risen halfway, he immediately patted his head.It is a very serious faux pas for a guest to post a greeting card and not arrive before noon the next day.

So he immediately got on his horse and galloped away.

In order to facilitate the transportation of materials, the small roads along the Wei River have been opened and expanded into main roads by craftsmen.The first seven-story cement building of Tianxia Civil and Military Academy has been completed, and the second floor is under construction for the second building.

Opposite the Civil and Military Academy, beside the Wei River, there are two exquisite wooden houses. Yao Silian and the great Confucian Yu Huanzhi are fishing in the small pavilion in front of the river.

Seeing the two great Confucian scholars, Liu Yuan slowed down and cupped his hands on the horse: "Students have appointments with others, so they go first."

Yao Silian waved his hand: "Let's go."

Seeing Liu Yuan leaving, Yu Huanzhi snorted: "If you have an appointment with someone, you should make a schedule. How can you be so flustered?"

Yu Huanzhi cares most about rules, he is an extremely upright old gentleman.

Yao Silian coughed and said: "Okay, okay, this Liu Yuan is considered a good young man. He has been in the official position for so many years, and he has never been corrupt, nor has he used his power to arbitrarily collect money to serve his mother wholeheartedly. He can be regarded as one of the officials. Model."

"Huh? Take the bait!"

Liu Yuan passed by Jinglei Division, because his horse was very fast, and was stopped by the Xuanjia Army.

"This is an important place for the Tang military. Fast horses are not allowed on the road! Who are you?"

The gleaming horizontal knife was about to reach his neck, Liu Yuan hurriedly said: "My official is Liu Yuan, Secretary of Sinong Temple."

After finishing speaking, Liu Yuan took out his official spy.

Several of the soldiers of the Xuanjia Army who were in charge of guarding the place were literate. They looked at the official spies, and after confirming that they were correct, they removed the horizontal knife: "My lord, please forgive me, my lord came on horseback. Didn't you see the notice on the road? ?”

Liu Yuan said embarrassingly: "I have an appointment with the crown prince, and it seems that I will lose my date, so I should ride faster."

The soldier returned the spy to Liu Yuan, and said with a smile: "The crown prince is not far away in Tianxia Manor, sir, just look for the tallest mansion in the manor."

The sergeants got out of the way, and Liu Yuan got on his horse and continued galloping towards Tianxia Manor.

There are farmlands on both sides of the road. Even though he knew that he was about to lose his time, Liu Yuan couldn't help getting off his horse to have a look.

When he found that the wheat in the field with manure applied was the same as the wheat in the prince's experimental field, he was immediately discouraged.

Those filth can really fertilize the land!
After a long journey, Liu Yuan finally arrived at Leng Mansion in time.

Li Chengqian waited in front of the door in his new crown prince's clothes, and smiled after Liu Yuan saluted: "It's really time for Si Qing to come, the banquet is already set."

Liu Yuan said with shame: "Earlier, I went all the way to check the mulberry situation in the farmland, and was stopped and questioned by the Xuanjia army. I almost missed the time. I am ashamed, ashamed!"

Li Chengqian waved his hand: "This place is not above the court, so don't call yourself a humble minister, please come in."

Liu Yuan followed the prince into the Leng Mansion, and seeing the elegant and exquisite interior of the Leng Mansion, he couldn't help admiring: "The courtyard arranged by Master is really elegant."

Li Chengqian said with a smile: "Men really put a lot of effort into this courtyard. Civil servants will find an elegant atmosphere here, and military officers will also find iron and blood here. Oh, my teacher was hurt a few days ago and is resting in bed. It is not suitable to wait." Sir, please forgive me."

Liu Yuan hurriedly said: "Don't dare, don't dare, I don't know if Master has gotten better?"

"My master doesn't need you to worry about it, come in quickly, I have been waiting for you for almost an hour!" Li Tai shouted from the restaurant door.

If the guests don't arrive, the host will not open the table.But Li Chengqian ordered the kitchen to cook a table of delicious dishes, which made Li Tai's mouth water.

When they usually eat, there are no more than five of them at the same table, and there are only three dishes, and they are afraid that if they can't finish it, it will be wasted.

Liu Yuan blushed, and after seeing Li Tai and Li Ke, he sat in the guest seat.

After five tastes of food and three rounds of wine, Liu Yuan cupped his hands and said to Li Chengqian: "Your Highness, you don't have to wait for the wheat to mature, I admit defeat! But I don't understand why the method of the predecessors who lasted for thousands of years is not as good as your highness's method?"

Li Chengqian put down his chopsticks and said, "Liu Siqing, let me just tell you my teacher's guess about the grass, trees and fertile land. If what you say is wrong, Liu Siqing just laugh it off."

Liu Yuan was very curious about His Royal Highness's mysterious master, and hurriedly waited for Li Chengqian to speak.

"What does Liu Siqing think the peasants in the world believe in the most?"

Liu Yuan bowed his head and thought for a while before saying, "Emperor Heaven, Houtu!"

"Whether it's civilians or us offering sacrifices to our ancestors, there are many ways, the most common of which is burning.

Therefore, my master speculated that the earliest act of burning straw should be to sacrifice to the soil and thank the gift of the earth. Later, it gradually evolved into the saying of "burning straw and fertilizing with plant ash".

Liu Siqing, have you never thought about what supports straw burning?Meat that has been burned by fire cannot be eaten. Will crops 'eat' the straw that has been burned? "

It was the first time for Liu Yuan to hear such conjectures and arguments, and after thinking hard for a while, he felt that this argument might be very reasonable.

Li Chengqian added: "According to my master, even if the straw is chopped into pieces and filled into the ground, it is better than plant ash. Liu Siqing might as well experiment like this year in the coming year."

Liu Yuan shook his head: "No need, what Master said is very reasonable, His Royal Highness, I see that soybeans are planted between every two rows of wheat in your field. I don't know what this means?"

Li Chengqian blushed now: "That's an insurance that my mentor set up for Gu. My master said that it was the first time for him to do such a thing as fertilization. I don't know how the effect will be, but he is sure that interplanting soybeans and wheat will improve wheat production."

This was the first time Liu Yuan had heard of this kind of statement, and he couldn't help asking: "I don't know why this is?"

Li Tai interjected: "Master Ben Wang said that there are nodules on the roots of legumes, which will produce nitrogen fertilizers. Most crops need nitrogen fertilizers. This is the first time I have seen the word 'nitrogen' in nitrogen fertilizers. The word 'Qi' for breath and the word 'Yan' for heat."

"Nitrogen fertilizer? A word formed by gas inflammation?"

At this time, Liu Yuan admired the master of His Highness the Crown Prince, he never thought that this master was so knowledgeable, he should pay a visit to him anyway.
