Although the transformation of the plough has not yet been completed, Song Xuan has already begun to train these animals in the tribe.

The easiest to train is naturally Uncle Deer and his three daughters-in-law, they are relatively docile in character, and have experience in animal power, when the children in the tribe are fishing, from time to time they will pull one or two out to help pull goods.

Although there is a big difference between carrying things and pulling force, this is all strength work, just walk forward with your head stuffy.

The main training is the synergy between them, exactly four adult deer, in pairs of two, the lasso shares a main rope, and then ties to a log, allowing them to drag the log forward.

As Song Xuan imagined, except for Uncle Lu, the other three were not very adaptable at first, but fortunately, there was Uncle Lu on the side to appease them, and they slowly lowered their heads and pulled forward hard.

The two cows in the tribe, although they have not been trained, have been relatively obedient when they were exchanged from the cattle tribe, but after they arrived at the Teng Snake, the heroes were useless and had never played a role.

Now, even with the lasso on them, the two cows only snorted, and did not struggle like other deer.

Song Xuan was worried at first that they might not be able to adapt to the feeling of being "tied up with five flowers", but after some training, the effect was quite good, and it basically didn't take much effort.

Now everyone is not very busy, and the land has melted away, except for the occasional colder and freezing, it has basically returned to its usual state.

Song Xuan took advantage of this time to take everyone to start dealing with the unfinished tree roots, which were the things that affected cultivation the most.

Although letting them rot in the ground is a good thing for the fertility of the land, the rhizomes on the surface still affect the planting too much, and the soil is loose, which will have a very big impact on the yield.

However, it is definitely impossible to make such a large area of land too clean, and after the main big roots are finished, it is estimated that it will be rotten clean in the remaining year or two.

And the fewer roots on the surface, the more convenient it is to use the plough later, otherwise it will be like the previous test plow, and from time to time it will encounter obstacles.

Everyone is still very experienced in digging tree roots, whether it is a small plot of land last year or at the end of the year, a lot of roots have been dug up.

After shaving, you can set fire to it when it is dry, and you don't have to burn it too much, just burn off the surface layer, but the more you burn, the better.

The fertility of the land is the last thing Song Xuan has to worry about, the land around the tribe can be regarded as black soil, at least the surface of these twenty or thirty centimeters, the color is gray and black.

Not to mention that the forest above was still burned to ashes by the fire, and many places still accumulated a thick layer of ash until this time.

Although the land was flooded several times last year, it is clear that it is difficult to absorb so much plant ash completely.

Song Xuan was even a little worried that the fertility of the land was too strong, whether it would burn the rhizomes of the rice, but thinking that the land was also made like this last year, there should not be any big problem.

In addition to digging up tree roots, it is also important to have a good irrigation system for the land.

Such a large area must still be divided, so that it will be more convenient to deal with it when the time comes, how to divert water is very important, the water is naturally brought down from the upstream, the same as the small land last year.

But last year it was only a small plot of land and a ditch would suffice, and this year such a large plot of land still has to be designed with a good flow of water so that it can be irrigated into each field relatively quickly.

Whether it is irrigation or water release, ditches are involved.

Song Xuan hadn't considered this matter before, but when he thought about it now, it seemed that this was also a very big project, and he regretted getting such a large piece of land all of a sudden.

It would take miles to dig a ditch around the field, not to mention extend it inward, and most importantly, it would have to be deep.

It's convenient to be too shallow, but it's not easy to get the water when the time comes, not to mention half a meter deep, thirty or forty centimeters is still necessary.

Song Xuan was also glad that the winter had allowed everyone to create a lot of tools, otherwise it would be really dark when he was busy at this time.

Digging a trench is obviously more important than cleaning the roots, even if the roots are not treated, which means that this year's yield is slightly lower.

However, if there is no proper irrigation system, it will be inconvenient when the rice is in urgent need of water, and it will have devastating consequences for the rice.

However, the roots still have to be dealt with, Song Xuan still left twenty people to be responsible for solving the conspicuous big roots, as for the smaller ones, it depends on whether there is time, if there is time, then continue to deal with it, if there is no time, he can only let him rot in the ground, and when the time comes, he can only trust the speed of those decomposers.

When Song Xuan remembered the importance of the ditch, he immediately rearranged the manpower, and did not even think about the design of the entire irrigation system.

Fortunately, no matter what, it still has to be done to circle around this field, so Song Xuan still has a lot of time to plan the internal route.

“……”

Seeing Song Xuan's big hand wave, everyone was a little speechless.

The amount of work in a circle alone has exceeded everyone's imagination, Shi Meng and the people have just come back not long ago, and they are about to come over to join in the fun, but they were directly caught by Song Xuan, and at this time, his mouth opened wide and confirmed to Song Xuan in disbelief:

"Divine envoy, do you really want to dig so much?"

"Well, you dig first, and there's one later!"

“？！”

Fortunately, although everyone was shocked, everyone's execution was still quite good, and after assigning the task, they returned to the tribe one after another, and took out the tools that had been polished a long time ago.

In addition to being used to plough the ground, the effect of digging ditches will be better, one will dig the land, and the other will be like a shovel, shoveling the loose soil to both sides and tamping it.

While everyone was digging a ditch, Song Xuan began to plan the internal route, and at the same time divided the land, hundreds of acres is only Song Xuan's rough estimate, and the size of the area can only rely on this guess.

There is no need to make a piece of land too small, especially now that the tribe is acting as a whole, and it is not alone, but the area is too large, and it is not convenient for subsequent processing.

Song Xuan is still ready to refer to the small field dug up for the first time, and it can even be a little smaller, three or four acres is quite good, so that one person can be responsible for a small piece of irrigation and weeding.

If the area is too large, there will be some more than enough to do.

A piece of land, forty meters wide and fifty meters long, is basically a little more than three acres, although the unit of rice is not popular among the tribe, but Song Xuan has already made a few rulers according to the length in his memory.

It's mainly calculated from your own height.,Although it's not a special standard.,But the error won't be too big.,Anyway, there's no unified weights and measures in this era.,Or what you say is what.。

Although it would be more convenient to divide the fields casually, Song Xuan still decided to be a little more rigorous, otherwise when assigning tasks, maybe everyone would have complaints, and it would also be inconvenient to record the output of each piece of land.

Although most of the seeds in the tribe are harvested last year, many of them are harvested from other tribes.

These seeds naturally can't be mixed together, and no one knows if the characteristics of different seeds are the same, and Song Xuan also wants to select the best ones for breeding.

From this year onwards, all the rice harvested as before will no longer be used as seeds, and Song Xuan will definitely have to choose the stout ones from them, and there will also be a demonstration field at that time.

The area is uniform, and it will be more convenient to calculate the output and assign tasks.

Song Xuan simply took a bamboo and bent it, and fixed a triangle with a rope in the middle, and the distance between the two ends was exactly one meter, and the length could be easily determined with this.

It just so happens that the drop of this piece of land is not particularly large, and the highest point to the lowest point is estimated to be less than one meter, and in general, the error after measurement is still very small.

In the end, it was divided into thirty-five pieces, although the last few pieces would be a little smaller due to the limitations of the terrain, but they were about the same as Song Xuan's estimate at the beginning, which was more than a hundred acres.

After determining the area of each piece of land, Song Xuan also used a small wooden stick to mark the places that needed to be dug trenches, and when the time came, everyone just dug along the log.

The outermost ditch is the most demanding, not only deep, but also wide enough to hold enough water, while the inner one is not so strict, almost enough.

After the arrangements were made, Song Xuan also joined the trenching team.

It was only after a long time that Song Xuan already had a sore back, last year these tasks were all handed over to the captives at that time to complete, subject to the high oppression of the Teng Snake, they themselves had no complaints, but at this time all the personnel were put in, and one by one they began to understand how hard the captives worked last year.

Even at today's meal, there was more food left for the captives, and although the Teng Snake didn't ask for anything, it was obvious that they were sure that they would have to do it faster than the Teng Snake people, and it would be a lot more tiring.

Fortunately, from the day they were taken prisoners, they did rough work, so they also dug a ditch for a day, but the performance of the captives was better than that of Teng Snake, unlike people like Teng Snake, who all rubbed their waists and sighed and walked back.

"Oracle, this is much more tiring than hunting!"

Seeing that Shi Meng still had the strength to complain, Song Xuan could only reward him with a roll of his eyes, at this time he was so tired that he didn't want to speak, he just wanted to eat a full meal, and then hurry back to rest.
