It is difficult to maintain the fertility of the same land for a long time with the method of slash-and-burn farming, and he is a veterinarian, not an agricultural expert.

In this regard, they actually have experience in this area, and they use the rotation tillage system, also known as fallow. To put it simply, when the yield of planted crops drops, change the land and cultivate it, wait a year or two, and then go back to planting the previous piece of land.

Of course, you can also interplant during the period, and plant different crops at the same time, modern corn and wheat, sweet potatoes and so on.

He also vaguely remembered that planting beans could improve the fertility of the land, and finally weeding and ploughing the ground, which was carried out a few months in advance, but now the conditions did not allow it, so slash-and-burn farming was adopted, and the fire was simply burned.

Anyway, now the land is vast and sparsely populated, and the land is barren, so we will continue to open up the wasteland.

Looking at the burning hillside, Su Yang suddenly felt a little worried, when farming can solve the food crisis, I am afraid it will be a heavy blow to the soldiers, just like the soldiers on the side of the Shenlong Clan have all knelt.

Women would move from gathering to pottery, salt, planting, and grazing. The men are still doing coolies, hunting or something, I'm afraid they will have to continue to be ruled by the matriarchal line, I hope it will flourish and decline!

That night, the people lit a fire outside the Simon tribe, sang and danced, talked loudly, and ate meat until late.

Early the next morning, the elders rushed back with some of the clansmen, each of them had a lot of things to prepare before the winter, Su Yang stayed with hundreds of people, and really responded to the call, although this was only temporary, but it was already very rare for his age.

The hillside by the river had been burned clean, but there was still smoke in some places, most of which had reached the stumps. Everyone is barefoot, and it's not appropriate to clear the land now.

"Prabhu, you take some people to hunt, and I will pick the rest of the camellia fruits."

He was very concerned about eating oil, uh, vegetable oil, and divided the team into several groups, so that everyone could pick the white camellia carefully, so as not to hurt the white camellia, otherwise there would be no fruit to pick next year.

I don't know if there is a plane tree now, if you can get some tung oil to light the lamp, it is not bad, the legend is that the phoenix is not a plane tree, so there should be a plane tree in ancient times. It seems that the paulownia can also be fried and eaten, and the bark of the sycamore tree can be twisted into a rope, which is also very ornamental.

There are more and more people with great strength, and there are more and more camellia fruits that can be picked, and a batch has been sent to the current Mang's tribe, which is dried and stored first, and when he is free, he is slowly studying how to squeeze out the oil.

It wasn't finished until after noon, so the team had to be divided into two parts, and Su Yang took half of the people to clean up the stones on the hillside and loosen the soil by the way. Loosening the soil, preferably by turning the soil underneath over it, will completely kill the grass roots, and allow the soil to fully contact the air, which will be beneficial to restore fertility.

The advantage of slash-and-burn farming is that when you burn it with fire, the soil has become soft and slightly hot, and you can warp the soil with a wooden stick inserted into the ground, and it is easy to clean up any stones that have fallen into the soil.

This hillside can actually be made into a terraced field, but it is too troublesome, so let's keep it as it is.

On the afternoon of hoeing day, sweat drops go to the soil, who knows that the Chinese food on the plate is hard work!

Su Yang can be regarded as experiencing this feeling, it has only been less than half an hour, he can't straighten his waist anymore, sweat is pouring out, and the wind is blowing and cold, which is really uncomfortable. On the other hand, the women in the team, including the merchant women, are still carefully loosening the ground. But the male warriors in the team were a little unbearable, and some were not suitable for this kind of boring work of bending over.

This is the difference between the nature of men and women, but looking back, men will also shout What famous flowers have masters, I will loosen the soil, this soil is not the other soil!

"Businesswoman, you let everyone be busy first, my stomach is a little uncomfortable!" Su Yang urinated and escaped, killing chickens with a cattle slaughtering knife, and physical work was really not suitable for him to do.

By the evening of the second day, the slopes were almost cleared, and if you want to increase the yield, you have to weed and fertilize after the beginning of spring. The camellia fruit has also been picked almost completely, and the harvest is quite abundant, counting the days, there will be snow in half a month at most.

Although he really wanted to stay and build the tribe, he didn't wait for me, and it was the right way to survive the winter first, so he had to hurry up and cut down the trees for most of the day, pile them up, and then withdraw with everyone. However, the people of the Sky Wolf will stay for two days, hunting together with the Mang tribe and stockpiling meat.

There are thirty people left in the team, which is exactly the number of people who can compete with the saber-toothed tigers, and safety is not a big problem.

shook off his messy hair, without any sense of flowing, but he didn't tie it up, what he wanted was this style, dou cool. Primitive people's hair grew more slowly, and there were not so many pure black colors, perhaps because of malnutrition, or perhaps because they were still in the evolutionary stage.

Besides, the lifespan of primitive people is a big problem, there are really not many male warriors who can live past the age of thirty, and women are even better, of course, some women have already tied their hair into small braids, whether they are tied with rattan or something, or coiled on their heads and necks.

In addition to the head, there are two other parts of the body that will concentrate long hair, three inches below the armpit and the umbilicus, and the hair in these two places does not grow, which is the result of evolution, and is related to the slow growth of the hair of primitive people in the current period, and even some primitive people hang up before waiting for long hair to reach the waist. In this case, if the barber travels to the primitive tribe, it will definitely be a tragedy.

As for the nails, the daily work is basically worn out, if the nails are long in winter, you can gnaw them off directly with your teeth, and gnawing nails is also common in modern children, as if it is because of the lack of something in the body.

Su Yang has actually always been curious about one thing, that is, what animal did humans evolve from? In his early years, he was misled by Journey to the West, and he always thought that humans evolved from apes, but in the end he found that there was no scientific basis and it was impossible to confirm this in modern times.

Perhaps, now that he has reached the primitive period, he will have the opportunity to figure out that the group of wild people is obviously half a beat slower than the outer tribesmen, and maybe one day he will meet the true ancestor of mankind, a species that has never been seen in modern times.

"Drive, drive!"

I had a wooden stick in my hand as a horse to ride, not to mention, I felt like I was running faster.

It's a pity that there are no wild horses in the forest, it must be in the plains, even if there are horses now, they can't run in the jungle.

There is no mount, in fact, you can create a "sliding pole", that is, the chair is tied to two bamboo sticks, and it becomes a simple sedan chair, but this thing can be comfortably lying on the chair, and because it is simple, it is specially used for scenic spots in modern times, and steep slopes can be lifted up.

Su Yang wanted to make a sliding rod, and let people carry it when he walked there in the future, even if it was a fairy day.

"Merchant, keep up."

Soon the merchant girl ran up, her hair was already shoulder-length, and she should be an adult before she could wait for her long hair to reach her waist, and she didn't know if Su Yang would be able to tame this fast horse by then.
