Li Zhi should say that he is still a pragmatic emperor. But Chang'an is the face of the country after all, except for this year of great famine, there is nothing to be done.

Therefore, there are many Huangzhuang farms around Chang'an, either the private estates of major families, plus the developed water conservancy, but now the drought still looks very beautiful. Therefore, Li Wei also went to a farther place, not far from Zhongnan Mountain.

Where there are fewer ditches, there are still some farms of large families, but there are also more farms for ordinary people.

Li Wei rode a horse, his riding skills were not very good, but he was not marching and fighting, and he needed the horse to run with all his strength, so it was too peaceful. Bi'er was about the same as him, because she was timid, and when she rode on a horse, her face turned a little pale with fright. After a while, it was close to Zhongnan Mountain, and the mountains were green and green. The upstream of the avenue towards Zhongnan Mountain is full of people.

But he wants to do the right thing, even if he runs away, he has the right to do good things for the people. If you don't run away and strive for peace to be the emperor, then these people are his subjects, and the country is his country, so you should do the right thing.

After taking a look, he galloped along a path to a cultivated field. When I got off the horse, the people were not officials, so what did they have to take a holiday vacation, of course, the Winter Food Festival was once a year, and some people were still resting. But there were also industrious people who began to sow and plough on the ploughed ridges. To Li Wei's surprise, he saw that many farmers were using the new plows. Of course, some people read his benefits, and then said that the prince or something, and praised it so much that even the ghosts and gods came out.

Even though Li Wei's face was still thick, he couldn't help but blush from praise.

Then look at the seeds, one is millet, one is sorghum, and one is soybean. Li Wei was surprised to see that there was actually a field where people were scattering seeds, rice seeds! But there is no need to plant seedlings and throw seedlings, and the harvest also makes him very suspicious.

Even millet and sorghum and beans need water, and I paid attention to it and saw many irrigation tools. There are hand-turned overturns, foot-pedal overturns, ox-pulled overturns, and you can also see a kind of connecting cylinder made of large bamboo. It's a remote place, there are still many ditches, and one of the ditches has been dug up for less than two or three years, and the mud on the ridges on both sides is still fresh. It also shows that the imperial court attaches great importance to water conservancy. It's just that the situation in many ditches is not very optimistic, and most of them have dried up.

He is really not as proficient in the ancient scriptures as those great Confucians, even if he is a lecturer. It is even more unfamiliar with the system. Even agriculture is not very proficient. But he grew up in the countryside when he was a child, and the countryside was still very backward at that time. is not an expert, he also participated in labor when he was a teenager, worked in the fields, at least not a layman.

For example, this waterwheel, maybe the Tang Dynasty waterwheel is very advanced than the Han Dynasty, but it may not be the best, such as overturning, the design of the shaft, vertical wheel, and horizontal wheel is very rough, and the precision is not enough, and a waterwheel has only one set of wooden gears, and the pumping efficiency is very low, and it is laborious.

looked at the big man who was spinning and overturning the car not far away, sweating profusely, and the corners of his mouth moved. In the end, I held back, and a new plow came out, which had been rumored to fly all over the sky, and another waterwheel came out, how could I release myself?

Continuing to observe, there are many large areas that are vacant. There is no need to ask about this, it is to cultivate "earth power". There was no fertilizer left, so I had to rotate the ploughing. Grass ash and livestock fertilizer were also used, but very little. The plant ash mainly comes from the output of cooking rice, which is abundant. The key is that the field is wide. In later generations, there was less than one acre of land per person in the places where peasants were concentrated, and now it is often several acres and dozens of acres. It was spread out and became scarce. Livestock is less fat, and many poor people lack livestock and use manual ploughs to plow the land.

Stood and pondered for a moment. Fertilizer is indeed a bit difficult to solve, recall, farmhouse fertilizer, plant ash, manure. Finally my eyes lit up. But he was silent, went down to the field, looked at the seeds that had been sown, and saw that some of the seeds were not very good.

He was watching, and the peasants didn't pay attention, thinking that these rich children were idle and bored, and it was fun to watch them.

After looking at it for a while, I knew what to expect, so I started talking with a farmer.

There is also manure, sometimes some grass and artemisia are chopped and put in the manure pit to rot to make fertilizer. But when it comes to safflower, it's blank. Fortunately, he was prepared, Li Wei quickly changed his words, Zi Yun Ying, Fei Lian, this is known. Some farmers also use young grass and eat it as a vegetable.

I was speechless about this, because Li Wei had also eaten it when he was a child in his previous life. Only later did I learn that it was poisonous. The crop is widely distributed, mainly on both sides of the Yangtze River, but it is also found in the Guanzhong region of northern China. Regardless of the yield, these fields are idle anyway, and in the "rotation of farming", God knows what year it will be, relying on some nitrogen, phosphorus and potassium accumulated by rain and dust to restore the soil fertility? Planting safflower grass is definitely better than idle.

The same is true for beans, who only know how much land is cultivated, it is food, and even know how much land is cultivated. Not to mention, these idle land to grow soybeans for a year, even if the yield is very low, the accumulated nitrogen fertilizer is ultimately stronger than the idle one.

Sowing seeds is also a problem, like this directly sprinkled seeds into the ground, there is definitely no nutrient bowl to raise seedlings, but I am afraid of trouble, small field seedlings, field transfer, it must be better than the current crop growth, high yield. Of course, because of the problem of the root system, wheat and other crops will definitely not be able to be transferred.

At this time, there were also two crops, and many fields were green and yellow. However, due to the lack of water, the growth is not good. There are even a few fields in the east and west, which makes Li Wei wonder if he can take back the seeds. Other farmers are digging small holes in the gaps in the wheat fields and planting sorghum beans.

He also knows that the selection of good seeds, but because of the wide planting and the thin harvest, at least for him, this is the word to describe it, but only to choose a crop that grows well as seeds, and to choose seeds in the form of seeds that are left for each one. No wonder Wang Rong drilled a hole in his plum's kernel before selling it.

As for single-plant selection and saline selection before the advent of large-scale hybridization, I have never heard of it. It is also this kind of widespread planting and thin harvest that restricts the peasants' thinking. Thinking of salt water selection, he thought of another thing, now salt is really expensive, a pound of salt costs three yuan, a better four to five yuan, but now he weighed a pound, it is very likely that it is not as heavy as half a pound in later generations. So after returning from the East Market, I checked the relevant documents, and only then did I know that I had not thought of drying salt in this era, but boiling salt appeared. But it is mainly pond salt, and in a few places there is well salt. With such an expensive salt, who is willing to use brine to select seeds?

But isn't that the case?

Another place, another conversation with a farmer who seemed to be very experienced, and the result was still the same.

In fact, these methods, in addition to being like a waterwheel or something, are recorded in most of the "Qi Min Yao Shu", such as the single selection and single storage of seeds, and the water selection before spring ploughing, only fresh water is used, and obviously many seeds that are not full can not be removed. Another example is the record of "the law of Fan Meitian, mung beans are the first, and adzuki beans and flax are secondary". Yesterday I deliberately flipped through this book. I still wonder in my heart, because many of the agricultural knowledge recorded in it is quite scientifically advanced, why is the yield so low?

I guessed in my heart, yes, a small number of people have already used a certain method, and they also know the benefits. But it is not standardized and promoted. One thing can be proved that the "Qi Min Yaoshu" has already explained the use of beans to replace idle fields with rotational tillage, but now?

A look at the many large open spaces in the four directions, some of which are on the edge of the ditches, despite the lack of water, illustrate the problem.

Of course, not everything written in it is correct, most of them are right, and he is lucky enough to know that a very small number of them can be improved, or they are wrong, or many of them are not right or wrong.

But how to convince parents, or each Zaifu, to promote the knowledge in "Qi Min Yaoshu" on a large scale throughout the country? Not to mention the re-correction of something in between.

After turning around again, his mind kept thinking, and it was noon, so he took the prepared Hu Biscuits and some side dishes, and sat on the edge of the ridge with the guards and Bi'er and nibbled on them. Because of thinking about things, even eating, my brows are furrowed.

Bi'er asked, "Your Highness, have you come up with a solution to the drought?" ”

Dizzy, solve the drought, although not an expert, but come up with one or two ways to increase production, maybe solve the drought?

Don't say anything about karez, although everything is backward in this era, we can't underestimate people's wisdom. Just like the Longshou Canal, built in the Western Han Dynasty, after more than ten miles of Shangyan Mountain, and then with the tunnel shaft construction, chiseled out more than 40 zhang deep well, the underground passes water. In fact, this method is a qanats.

That was the Western Han Dynasty, and the Tang Dynasty?

Don't say that he doesn't have that much ability, but he has the ability, build an airplane, come to artificial rainfall, can resolve the drought in such a vast arid area?

"No, it doesn't rain all day, and there is nothing to be done about it. Are you thinking about something else, do you remember that I came to inspect it yesterday and looked through "Qi Min's Technique" for today? ”

"Remember, it was the slave who took it off the bookshelf for you."

"Then do you remember what you said to Dai Xianggong at the labor banquet alone, the yield is too low."

"Remember, but Dai Xianggong is right, compared with the Han Dynasty, the grain yield per mu in our dynasty has nearly doubled."

"If we can increase food production, why can't we continue to increase it?"

"But that's hard."

"Things are man-made, just like a stubborn disease of loneliness, which is difficult to cure. But under the exercise, isn't it getting better now? ”

"Your Highness, you are really a good prince."

Jiang Si said very much, "Because I went out of the city, I brought ten guards over." Several guards said together.

The heart is broken.

What other officials inspected, it was superficial work, and everyone knew it. But when the prince inspected the people, he really looked at it, and he didn't make any noise, and when he went to the field, he not only looked, but also asked, and now he was thinking about it. Whether you can figure it out or not, that's one thing. But this intention is commendable.

"Don't boast, the people expect so much from Lonely, but Lone is powerless and uneasy. Always want to make a contribution in return. ”

Speaking of which, the sun was a little hot at noon, and a lot of sweat broke out on his forehead. Bi'er wiped it for him with some worry, and said, "Prince, you have also seen it and asked it, let's go back to the palace." ”

Looking at her concerned and serious expression, the warm spring breeze blowing on the ridge, and the slight virgin fragrance on her body, Li Wei was a little moved.

Spring is deep, and people always have a little thought. There are many girls who make him excited, such as Xiangxue and Hualiu who are still in the East Palace, or the little hot girl of the Xu family, but they have a lot of scruples. Even Yang Min also has a scruple and may not be able to understand her heart.

But there will be no problems with Bi'er.

Isn't Bi'er a little younger, it doesn't seem to be small, besides, there are people who get married and have children at the age of twelve or thirteen in this era......

Thinking wildly, he replied, "Since it's out, let's turn it around again." ”

I calmed my heart and looked at the endless wilderness, and thought of it again. It's not very easy to do, such as this safflower grass, or beans, which can only see the effect for several years, it is impossible to plant a season of safflower grass this year, and then a season of soybeans, and then next year it will be able to produce ten stones per mu, shaking the world, and quickly and widely. If you want this theory to attract the attention of the whole country, you can't scruple about it, and I'm afraid it will take decades for it to be recognized.

It's too difficult, what do you say now, what nitrogen, phosphorus and potassium, well, even the demon Li Chunfeng, who had just passed away not long ago, stood in front of him, and he wouldn't believe it.

But some can still be on. Originally, there were many imperial villages outside Chang'an, and their parents, and even their grandfather, Li Shimin, put agriculture first. If you stand in front of the counter and shout for business, it is estimated that the official can kneel all the way from Taiji Palace to Dongshi. But participating in agriculture, none of the ministers will speak.

With this convenience, now it is just time to grab the time, come to a nutritious bowl to raise seedlings, the field is irrigated, there are not many safflower grass outside Chang'an City, but there are, many of them grow under the Zhongnan Mountain, so that the people can eat them as wild vegetables, or as a prescription for dispelling wind and clearing heat and wind. He is the crown prince, and when he gives an order, he will collect a lot, or deliberately let people bring the bean branches and put them in the field together. When the seedlings grow up, drain the field water, and the green manure is almost ready. Then use some scientific methods to plant.

Don't make too much first, as long as you take care of it well and see the effect, your parents don't promote it, and there are always people nearby who are curious to imitate. But he has a lot of scruples, and the yield is a little higher, if he makes a four-stone field and a five-stone field, it will cause a sensation all over the world...... And if served properly, it's not impossible.

Really worried......

The identity of this prince......

At this time, a person rode a horse, galloped quickly, came to the front, turned over and dismounted, looked at Li Wei and asked, "Your Excellency can be the prince?" ”

The guards immediately became vigilant, and Li Wei waved his hand to stop it, saying, "Exactly." ”

"The subjects see the prince," he turned over and saluted, and then said, "Your Royal Highness the prince, something bad has happened. ”
