In fact, artificial cultivation of mushrooms is a very simple thing. The complicated thing is to simulate the breeding conditions and climate of mushrooms. Therefore, the wild mushrooms in some specific areas can not be popularized to the whole country, such as Flammulina velutipes and Pleurotus ostreatus. Many wild mushrooms can only sell processed products after artificial cultivation, such as the series products of many wild mushrooms in Yunnan.

Xue Lang said cheerfully, "in fact, cultivating mushrooms artificially is a very simple thing. As long as you understand the principle, it's very easy to do it. The difficulty is to simulate the environment and climate of mushroom growth. As long as the environment and climate are simulated, mushrooms will grow naturally! "

The sage nodded and asked, "what is simulation?"

Xue Lang had to explain what simulation is.

Seeing that Xue Lang was right, he was not shooting at a target. The sage said with a smile: "if you look at the Qing family, you must be sure. In this way, I will wait for the Qing family to offer fresh mushrooms to me in winter!"

Xue Lang resound to answer a: "here!"

The king of Qin said with emotion: "if you want to come to a foreign country where you come back, you must be very skilled in farming techniques. You should have a unique way of teaching and educating people. Therefore, Fang Xue Jun Gong is such a erudite and versatile talent?"

The king of Qin has a keen observation. He can always find the key points before his father and brother, and see what they can't see. It's a gift!

Xue Lang secretly looks at Li Yuan and Li Jiancheng. Li yuanmu's admiration has no time to step down. Li Jiancheng lowered his head and could not see his expression. However, he should not be happy. As a mortal, I am always set off by a genius Your highness is really good psychological quality!

If you let Xue Lang be compared every day like a fool, maybe he would have abandoned himself! Therefore, Li Jiancheng is not a poor man, nor a really stupid man. He is just compared by his talented brother No comparison, no harm.

Xue Lang pressed down his thoughts and said, "since the king of Qin asked, the minister said a few words. Agriculture is the foundation of our country since ancient times. This is a national policy, and its status will not change after a thousand years. As the saying goes, food is the most important thing for the people

Food security is the national strategic security. Not to mention the ancient times when there was no food and clothing. Even in modern times, grain production was also a highly valued industry by the state. Therefore, it has always been emphasized to maintain the red line of arable area. As a big country with a large population, if we can't be self-sufficient in food and rely too much on imports, we will be holding our necks directly.

Xue Lang said: "in foreign countries, agriculture as a specialized subject, there are many people to study and study. Some people study how to improve seed yield, others study the improvement of farming technology, and others study how to improve the technology of disease resistance, pest control, drought resistance and waterlogging resistance. There are even special people who often go to the countryside to teach ordinary people how to better cultivate and manage the land, and widely apply the research results to the actual situation, so as to achieve the effect of increasing the yield

"Is it suitable for us to adopt this policy in Tang Dynasty

In addition to the king of Qi, the sage, the prince and the king of Qin all looked at Xue Lang eagerly, waiting for his answer. Xue Lang thought for a moment and said, "according to what I have seen and heard since I returned to the Tang Dynasty, the foundation has not yet been achieved. First of all, the cultivation technology is backward and there is no pattern; almost all of them have their own experience. There is a big gap between the crops cultivated by good hands and those by ordinary people. Second, people's wisdom has not been opened up, and there are still too few people who can read! Throughout ancient and modern times, there have been several agricultural books, which is not to say that there is no record of excellent farming methods in agricultural books. There are records in agricultural books. It can be said that as long as we read the agricultural books thoroughly and combine with the reality, it is not difficult for the rich to be rich but for the small ones. However, even if such practical agricultural books are not widely spread, in the final analysis, there are too few people who can read! "

It is a huge project for the whole people to get rid of blindness and to read, not to mention the present Tang Dynasty, even in the modern era with developed economy. After all, learning cultural knowledge is a very subjective thing. If someone doesn't want to learn, it is impossible to force them to learn.

Xue Lang concluded: "the so-called governance of a big country is like cooking small dishes. Even if the policies and measures that benefit the country should be implemented and achieved, it is not a matter of two days. In particular, teaching and educating people and opening up the wisdom of the people is a kind of painstaking effort, which needs the efforts of generations to be effective. "

Li Yuan said in a deep voice: "it is imperative to open up the wisdom of the people. My generation can't finish it. My descendants should continue to promote it. One day, all the people under the Tang Dynasty will have food to eat and clothes to warm up. Can the prince remember it? "

There was a glimmer of joy in the prince's eyes, and then he saluted solemnly: "I remember it! When you go back, you can engrave the words of the sage on the plaque and put them in the main hall. You can watch them every day to remind you that you will never forget them! "

The king of Qin respectfully said, "so are my ministers."

The king of Qi saw this and followed him: "so do the children's ministers. Never forget the sage's instructions."

"Great kindness!"

The nodding saint is gratified.

Xue Lang was a little confused about how to cultivate mushrooms and open up people's wisdom. However, it was a good thing that Emperor Li Tang and his son had ambition. He was afraid that the emperor had no ambition and wanted to enjoy himself, and the country would be ruined!"Newspaper! Urgent report! It's a hundred and eight leagues

A couple of father, son and brother work together to build the inspirational scene of home and country, and break the existing scene with an urgent report. Xue Lang called out a pity secretly, and looked at Li Yuan --

the saint's face was complete, and he directly called out: "present it!"

Xiaohuangmen immediately stepped out, took the urgent report in and presented it to Li Yuan. Li Yuan took it, directly tore open the wax seal and read the letter. After reading it, Li Yuan's face changed and his face was startled.

the king of Qin immediately asked, "dare to ask the sage, what's the news?"

Li Yuan, calm and worried, said: "the Turkic Jieli Khan led 150000 troops to knock on Yanmen gate, and they have already entered Yanmen pass and disturbed Bingzhou; other departments have disturbed Yuanzhou and fallen into the great earthquake pass! Set up the xuanzheng hall, and the internal servants will ring the bell to call on all the officials to discuss the matter! "

"Here it is

The little yellow men in the hall were busy at once.

In addition to following Liu heikai everywhere to do chaos Turks, Jieli Khan this biggest evil also came! I don't know what happened to your highness. According to the war report, it seems that the Turks have not passed away, but they are still not at ease.

you should finish the affairs in Beijing early, and then go back to Weize pass as soon as possible! If you don't look at it in person, Xue Lang is really worried.

Full of heart to follow the sage to the xuanzheng hall. After the bell rang all over the city, it was only half an hour's work. All the officials who were in charge of the five grade and above positions in the central government of Beijing gathered in the xuanzheng hall in neat robes.

"Chaoyi begins!"

Xiaohuangmen called out, the ministers saluted to Li Yuan: "see the sage, Saint Wanfu."

"You are welcome."

Li Yuan turned his head and looked at xiaohuangmen: "read the urgent report just received to all the ministers."

"Here it is
