Although the white roots were numerous and covered almost the entire wall of the pit, none of them actually grew outside the wall, as if there was a transparent wall blocking them.

Just when Xu Yi was looking at the pit wall in a daze, those fibrous roots disappeared as if they were suddenly like ice and snow in the spring season seeing the sun.

It's interesting that no rhizomes will grow in.

Make up a picture: a huge cellar, surrounded by white roots that look like wallpaper.

As for the disappearance of this root, it is not difficult to understand, there is no source of nutrition, and the roots cannot continue to survive, so they are all absorbed, Xu Yi thought.

Of course, the evidence of such a mint plant still seems to be too little, and Xu Yi took potatoes, sweet potatoes, and even watermelon seeds, soybeans, and other things that are easy to turn out of the soil for repeated tests.

In the end, Xu Yi came to the same result.

Even if the cellar is left open, as long as the volume of the space covered by the cellar can be guaranteed to exceed half of the total volume, and at the same time maintain more than the volume obtained in the previous experiment, then even if the cellar is planted in the open air and poured with space water, these things will not take root at all. As long as the water seeps out, these things can still be basically kept clean when they are dug out, of course, what will happen if they are buried in the soil for a longer time, and what will happen Xu Yi is not clear, this can only be observed for a long time.

However, if the volume of the covered space is less than half of the total volume, then these buried things will take root and sprout directly as long as they come into contact with the space water, whether they are planted on the covered side or in the open air, no matter how so!

Xu Yi also discovered. Whether planted on or around the lid of this cellar. As long as the space is not less than the previous standard. Then the root system below will never grow into the cellar, just like before, spreading and growing along the four walls to the bottom of the coffin.

Of course, if the volume of the cover is too small, it is difficult to say. If there happens to be a rhizome growing in the direction of the cellar, then this root system is often like a mess, growing horizontally and vertically in the cellar, even when Xu Yi planted a potato. And a small potato grows in the cellar!

Xu Yi naturally didn't have to care about this result, and he didn't have to worry about the roots of this plant growing into the cellar.

After all, this is completely made of soil, and the pit wall is too soft, and more roots can be regarded as an effective reinforcement of the pit wall.

If it weren't for the fact that vegetables, sweet potatoes and other things were too far away from the tree land he had set aside and it would be troublesome to carry things, Xu Yi would have thought about building the cellar in the woods.

In this way, even if those trees are bigger, those roots will surely be able to better strengthen the pit wall.

In addition, Xu Yi also tried to throw some soil into the cellar, after all, the space had been shown before, if the pit was filled with soil. This hole will be filled by itself!

If nothing should change, Xu Yi would have to be careful when he dug this cellar and used it. If you accidentally get some soil, then this cellar is equivalent to digging for nothing, especially those potatoes, ginger and other things, do you have to put them in bags, make space to turn all the soil on it into water before you can put it in the cellar again?

After the experiment was completed, Xu Yi was relieved.

It's about the same as the previous results, if the cellar covers more than half of the total space, and it is larger than the previously calculated volume, then it doesn't matter how much soil is filled, it just piles up there and doesn't change at all.

However, even if you put something in it, so that the remaining volume of the cellar is less than the standard of the fan surface, as long as you fill the cellar with soil, the bottom of the cellar will soon grow soil on its own, and the whole cellar will be leveled little by little.

Even the contents of the cellar will be buried in the soil, and even worse, if the straw that has been roofed is also covered with soil, the straw will be completely absorbed by the soil.

Even cuttings that can be taken up if they are completely buried in the soil, and only those that can be planted are preserved properly – or this is considered a kind of planting in this space.

After the experiment, Xu Yi felt very satisfied.

It never hurts to grasp the laws and make better use of them within a feasible framework, rather than violating them.

As for things that are completely unreasonable, Xu Yi is not too entangled, he has no references, let alone experiments to use, how to explain it?

Even if he can explain it, who do he need to explain? According to these laws, Xu Yi imagined the method of using them, and found that these rules are all beneficial to him, so why bother with them!

After looking around a few clearings, Xu Yi prepared to put the vegetable cellar in the place where the potatoes had been dug up before.

This place is close to the periphery of the space, you don't need to walk around often, this cellar mouth has little impact on you, at most you waste three or four square meters of space, don't worry too much.

This is enough to dig a large cellar by yourself, and it is close to the vegetable fields, so that you don't have to move to the tent after harvesting.

If you want to bring something out of the space, you can come here directly when you come in, all kinds of convenience, why not!

For the rest, whether the vegetable can be preserved for a longer period of time, as long as it can be kept as long as it is kept in a tent.

As for whether long-term storage will lead to a decline in the quality and taste of vegetables, and even lead to the accumulation of nitrite, Xu Yi can't be sure for the time being, so he can only put something in it first, and wait until it is long enough to slowly verify it.

Once the location is chosen, the rest of the calculation depends on the material.

Xu Yi was going to use his basswood to build the load-bearing components of the cellar, after all, this was not like the outside world, the soil on the four walls was too soft, and Xu Yi did not dare to guarantee that directly pressing the upper cover on the four walls would not lead to such a danger as a collapse.

After carefully calculating the length and quantity of his basswood, Xu Yi drew a rectangle on the ground that was more than four meters wide and six or seven meters long, and threw off his arms and dug it.

A deep pit almost one meter deep was dug out to the bottom of the pit, and after it was leveled, Xu Yi stopped, and then at the bottom of the pit along the four walls inward more than a foot wide, and then drew a rectangle.

This is the real cellar when it is dug down.

Of course, with such a deep cellar, I was afraid that I wouldn't be able to climb up after digging it, so Xu Yi went to get a ladder and put it on the edge of the pit, and then began to dig along the line where the finished stone was drawn.

Xu Yi is going to dig a deep cellar, so that no matter how much he loads it, it is impossible for him to install it too high, and it will not affect the safety of the cellar. For added safety, he was even prepared to open the door in the direction of a plug in the cellar, instead of placing the opening above the cellar as in the traditional cellar.

In this way, you can make a door frame in the future, which also makes the side of the cellar roof exposed to the surface, so that even if you really fill the cellar, it will not affect the safety of the cellar itself.

Xu Yi calculated that as long as he didn't dig water, he could dig the cellar to a depth of two to three meters, so that he could use up almost half of his basswood, and he didn't have to worry about the lack of wood.

Of course, for such a large project, the earthwork alone will cost hundreds of cubic meters, and it is not possible to dig it in a moment or three.

Xu Yi went to eat when he was hungry and went to sleep when he was tired, and it took him thirty or forty hours to dig the cellar.

Looking at the cellar that was almost three meters deep, and the bottom of the pit was still dry and refreshing, Xu Yi nodded with satisfaction, and it was time to prepare for the finishing work!

Xu Yi went directly to remove the bamboo poles from the top of the wood, then carried the thick bamboo poles to the edge of the pit, and then carried half of the basswood on the wooden stack.

When moving the wood, Xu Yi also found a problem, the bottom two layers of wood were as wet as when they were cut down before, and they were not dry at all!

However, even if the wood on the third layer is completely dry from the bottom to the top, or due to the influence of ambient temperature, there is no crack on all the wood sections, and the whole wood is as good as ever.

Xu Yi tried to remove a piece of wet wood and throw it on the ground, and then found that white mist quickly emerged from the place where the wood touched the ground, and it behaved exactly like the original behavior of those tree roots!

Hurriedly moved the wood back to the shelf, and checked again, Xu Yi found that the bark on the outside of the wood had been completely absorbed from the previous contact with the ground, and the white trunk was exposed inside, as if it had been peeled.

Not daring to try again, Xu Yi tossed the timber stack again. There is not a lot of wood that is dry underneath, only enough to lay a layer underneath, and Xu Yi has no choice but to wait until the top layer of wood is dry again, and then toss the wood stack again to let the middle layer dry completely.

After being busy, Xu Yi took a tape measure and an electric chain saw and directly cut off the wood. After the material was ready, Xu Yi simply made mortise and tenon joints according to the distance between them, assembled them, and made them into rectangular nest frames that looked like two legs stretched out from below.

Except for a wooden frame that was to be erected on the outermost part and intended to be reserved as an opening in the cellar, all the other seven or eight wooden frames were identical in form.

After assembling all the wooden frames, Xu Yi went down to the cellar and stepped on the ladder directly on the pit wall, digging a continuous shallow ditch on the two side walls and the bottom of the pit at a distance of more than one meter away, the width and narrowness were similar to the thickness of those tree trunks, but the depth was only half the diameter of the tree trunks.

Where the two side walls meet the bottom of the pit, Xu Yi also dug a deep pit about the same depth as the two feet of the wooden frame.

After working for a long time, Xu Yi dug these holes, and then pushed the wooden frames one by one to erect them vertically along the trench in the cellar. (To be continued......)
