"You can plant the herbs first to try the effect, but don't expect any obvious improvement in a short period of time!" Liu Che nodded slowly, agreeing with Liu Ponu's seemingly unreliable and very reliable opinion.

The cultivation of medicinal materials is not uncommon in Dahan, but it is not something that can be cultivated by any medicinal material.

Liu Che didn't have time to worry about those things, so as before, he directly left the matter to Liu Ponu to solve.

Who let this be something he brought up? Who will solve if he doesn't solve it?

As for other ideas, Liu Che is still a little forced in his heart.

What were the living conditions before?

Not to mention eating well, even if you can't eat enough, people can only shrink at home in winter because of the lack of warm clothes, and dare not go out.

What are the living conditions now?

As long as you are willing to put down your body and do it, not to mention that it can make you eat all at once, at least there is no problem to worry about hunger all year round.

Although Quyuan plough made them start to go into debt, the benefits were real.

Even if there is no zigzag plow, with the help of the water conservancy system alone, one or twenty catties of grain can be harvested per acre of land.

The amount of one mu to increase production seems to be small, but what if dozens of acres are added together?

The increase in production alone is enough for the family to eat for two or three months.

Therefore, even if Liu Che does nothing in the future, the premature mortality rate of young children will be lower than before, although the reduction may not be so large.

"In addition to medical care, we must also start arranging the nutrition of food!" Liu Ponu continued.

"How?" Liu Che was a little surprised, but he didn't feel too surprised, and asked calmly.

"The pastures in the north can be arranged, there have been no Huns for a long time, and the pasture grass is fat enough, but we can't graze endlessly like the Huns, and every area must be well planned, and the maximum number of livestock for grazing must be limited, so as not to gnaw this year's bare piece and next year's bare piece will not grow anything." Liu Ponu recalled the current situation on the grassland, and he couldn't help but feel a little worried.

The Huns were like this, when they saw that the grass was fat, they would gnaw it to death, until it was bare, and then continued to gnaw in another place.

Although the grassland is very large, the grassland is actually not big, tens of millions of cattle and sheep have to gnaw so much every year, where do they get so much grass for them to gnaw?

And this barbaric grazing behavior has also opened the door to grassland desertification.

That's right, deserts have already appeared on the steppe now, although the area is not large.

In later generations, the situation was even more serious, and Mongolia, the entire country was founded on the steppe, and there was not much suitable place for grazing.

Anyone who has raised sheep knows that they are almost not picky about rations or anything, and they can eat whatever they want.

"The Ronin Who Started from Douluo"

But if he was allowed to find food to eat, he would be able to gnaw that piece bare, even the grass roots, which was the main reason why grazing was forbidden in many places in later generations.

"In addition, there is a no-grazing area at intervals, and I have studied the growth environment of grass, and every autumn as the grass plants wither and yellow, the grass seeds begin to mature, and when the crops are ripe, they almost fall off at the touch of a button, and most of their propagation methods are through the wind as a carrier to fall freely, and after falling to the ground, they begin to settle here, and when they fall to the ground, they will take root and sprout in the spring of the next year."

"The no-grazing zone ensures that our pastures have a steady stream of grass seeds falling every year, so that there is enough space and grass for grazing each year." The Han Dynasty version of the environmental protection law was like this, and Liu Ponu said it happily.

Of course, even if Liu Ponu doesn't say it, in the next 100 years, the Han Dynasty will officially promulgate the first documented environmental protection law, which is drawn from the Hanging Spring and promulgated by Emperor Ping of the Han Dynasty.

So don't think that the ancients didn't know how to protect the environment, the ancients actually made practical actions a long time ago, but later generations didn't know and didn't pay attention to it.

Liu Che's face gradually became heavy, I don't know if Liu Ponu's method can work, but this idea is really worth trying.

"Is that what you said about why not eat millet food? Have you ever calculated how many cattle and sheep the imperial court needs to raise on the grassland to meet the needs of the Han Dynasty? How much is consumed on the way? After arriving in various places, can the price be acceptable to the people? Liu Che suddenly remembered what he had said to him when he first met Liu Ponu when he mentioned the drought in Kanto.

At that time, he just felt that Liu Ponu was too naïve, so he didn't pay attention.

But now it seems that he has even figured out a way to protect the pastures and graze them sustainably.

Was this just a flash of inspiration?

If Liu Ponu hadn't said that he had studied the growth environment and laws of grass plants, Liu Che would most likely think that this was a flash of inspiration, but he even figured out these problems, which can only prove that this kid was thinking about solving this problem from the beginning.

"Meat is just a supplementary food, and I don't plan to let the people eat meat as a staple food!" Liu Ponu glanced at Liu Che and continued: "I have also studied this, the size of the Huns is generally much larger than our strong men, but in terms of strength alone, the Huns are inferior, and later I studied the Huns who took refuge in us!" ”

"It turned out that after they took refuge in us, their body size has shrunk to varying degrees, but the strength on their bodies is much greater than before, and later research found that their reminders are related to eating meat, and the weakness in their bodies is due to the lack of salt!"

"After taking refuge in us, they are no longer short of salt, but they are short of meat, so while their strength increases, their size also shrinks."

"In the same way, I also found that people who live by the sea have much better vision at night than people who live inland, and I asked them to do a survey and found that all the people who have good vision at night are people who eat fish a lot, and then I let people try it and find that after eating for a while, their vision at night really improved, especially in younger children."

"Although meat and fish cannot be used as staple food, although the energy consumed may be greater than cultivating grain, but these two are also essential, so in terms of food, the imperial court should make some appropriate changes, mainly crops, supplemented by cattle, sheep and fish, not to mention too much, at least to ensure that everyone can have more than half a catty of meat to eat every month."

"As for transportation and preservation, this is simple, beef and mutton can be slaughtered directly in the grassland, and fish can also be slaughtered at the seaside, and then transported back after being made into dried meat and dried fish, so that there is no need to worry about consuming too much on the way, let alone worrying about spoiling or something." Liu Ponu smiled and proposed with a sly face.

Fresh meat is delicious, but it's too expensive.

That is, a family like Liu Ponu can eat fresh meat at once, and the others are ministers in the court, even at the level of Huo Guang, and they dare not guarantee that they can eat meat at every meal.

Home rearing?

Before, no one had food to eat, so where did he go to raise poultry?

Even if you raise a chicken, you are reluctant to eat it, either to sell eggs, or to sell it to nobles in exchange for money or food.

Plundering from the outside is a good way, but the grassland is still far from Chang'an, and how to transport the plundered livestock back is also a problem.

On the grassland, you can let him eat while walking, what will he do when he arrives in the mainland?

You can't let these cows and sheep eat the crops, right?

Therefore, after all the wars, large quantities of livestock were rarely brought back, and most of the trophies were digested by the troops on the spot.

This not only solves the problem that the loot is difficult to transport, but also greatly relieves the pressure of logistics transportation.

Of course, that's all in the past.

"A sheep is only twenty or thirty catties of meat, and even less when it is made into jerky, and then a truck can pull back hundreds ......of sheep, and the most important thing is that this is a business, and it can make a lot of money."

Liu Che's interest in this matter was not so high, but when he heard that Liu Ponu wanted to do this kind of thing as a business, his interest was instantly raised.

In order to motivate the population, Liu Che gave up a lot of calculations, and in the future, the army will also change to a new army, which needs money to solve.

Well, there is also the Jianzhang Palace that Liu Che will never forget, and it is said that the shutdown has been long enough, is it time to consider starting work?

"How much money can I make?"

"If you put it at the national level, you can make tens of millions of dollars a month, you can do it with your eyes closed!"

"That's it, you're responsible for this......"
