Chapter 553: The regrettable rotation of wheat and beans

"Come on, come here with a drill and leave a mark."
Seeing the dumbfounded look of the Wus, the divine child Han Da, who was very useful in his heart, pretended to be calm and calm, and reached out to point at the mark he twisted out with a wooden stick.
This is the center of the circle. At this time, make a mark and find the center of the circle again if you save time.
"Ah good!"
Staring at the wood in a daze at the simple compass, he was stunned for a moment, and hurriedly used a drill to chisel out an indelible mark here.
Han Cheng used the same method to draw a circle on another stone slab with the same radius as the previous one.
No need to say anything from Han Cheng this time, the wood consciously chiseled out a shallow trench along the circle with one hand with a hammer and the other.
As for the simple compasses, they were in Wu's hands by now.
Like a child with a novel toy, they leave circles of different sizes on the ground and enjoy it.
Stone and limping. Two people who wanted to experience this wonderful tool with their own hands. After waiting for a while, seeing the witch still looks enthusiastic, so they found the rope and tree stick and joined the circle on the ground. Go in the ranks of the circle.
Before long, many circles of various sizes appeared on the ground of the Qingque tribe.
After these guys painted, they stood up and admired them. They were silly and happy from time to time. They were obviously satisfied with their masterpieces.
‘These guys who have never seen the world. ’Han Cheng slandered in his heart.
‘It’s just a simple compass, is it fun to have such a novelty? ’
Facts have proved that simple compasses are so fun.
Not long after the belly defamation, the son of Han Da also joined the ranks of circles on the ground.
Moreover, his technique of drawing circles with simple compasses is obviously superior to that of the witch, stone, and crippled naive ghosts.
The regular pentagonal pattern made up of five semicircular arcs that appeared inside the circle made Wu and the others amazed.
It turns out that in addition to drawing circles, this thing can also draw such complex and beautiful patterns, which is really amazing.
As a result, with the addition of Han Cheng, there were already some additional people who didn't want to play, and immediately became interested again.
Such a simple and interesting tool soon became popular among the Qingque tribe and was greatly welcomed by these primitive people who lacked entertainment activities.
Especially those minors, one by one is more happy.
So that in the following period of time, the Qingque tribe can see large and small circles everywhere inside and outside.
Even the wall of the wall and the wall of the tukang have not been let go, which is extremely crazy.
The wood with a mask has hardly stopped clanging with hammers and iron brazing in these days.
As a small piece of stone peeled off, a fan gradually took shape.
After learning the lesson of drawing the circle last time, Han Cheng did not let the wood come at the bottom of the stone mill where small trenches were needed. Instead, he drew lines of different lengths with small wooden boards and small stones. .
Then let the wood chisel along these lines.
Of course, these lines are not rays extending from the center of the circle to the edge of the circle, because after digging out, the more you go to the outside of the stone, the sparser the grooves, and the effect of grinding things is not very good, so draw Become a series of parallel lines.
It is not easy to draw parallel lines on a circle. Of course, except for the line with the diameter as the middle, and then line up on both sides.
The effect of the stone mill made according to this painting method is not as good as the radial effect.
Han Cheng's painting method is to divide the circular grinding into several parts, and then draw parallel lines in these parts.
The lines between every other part are parallel to each other.
In this way, there will be as many grooves on the stone mill as possible, and these grooves are not perpendicular to the edge of the stone mill, which can avoid pouring beans from the mill eye, and run along the groove before milling. The embarrassing thing that came out happened.
It is foreseeable that the wise ancients who first invented the stone mill must not have invented the stone mill like this, but in the process of using it, they constantly discovered the shortcomings of the stone mill, and tried every means to improve it. Make the stone mill the way it is now.
This is the advantage of the traverser, who can stand on the shoulders of giants and pick fruits, and directly absorb the wisdom that has been continuously improved and passed down from generation to generation.
Fortunately for Han Cheng, he is no stranger to stone grinders. This is because he had a grinder at home when he was young.
The things of making jelly with peas and making noodles are not too dry.
When Han Cheng drew the line and the wood clanged along the line and started chiseling, the could be harvested.
Harvesting rapeseed can't wait until the rapeseed is ripe, but it can be sickle if it turns yellow.
The reason for such anxiousness is that every plant is a good mother, and there is a way for the child to leave his arms and live independently.
Dandelion puts a small umbrella on her child, which can be taken away by a gust of wind, and Xanthium puts on her child an armor with thin hooks. When animals pass by, they can take them to a distance.
As for pod-bearing plants such as rapeseed and beans, the method used is sunlight.
When they are ripe, they can easily split the pod and let its children into the embrace of the dirt.
Of course, Han Cheng didn't want to let it happen. They let the rapeseed enter the arms of Mother Earth, and their tribe has been busy this year.
However, compared to the past, this year's harvesting and subsequent processing are much quicker and easier, thanks to the many more slaves from the Qingque tribe.
Everyone worked together, and within a few days, these rapeseeds were harvested and processed.
Then, taking advantage of a good day, the land where the rapeseed was harvested was turned over and planted with late millet.
After the late millet was planted, the planting of soybeans was gradually put on the agenda.
It would be great if there was wheat.
Han Cheng thought with regret.
If there is wheat, the rotation of wheat and soybeans can be carried out. The time is just right. Harvesting two crops a year is simply beautiful.
In addition, soybean roots will also gather a kind of fertilizer called ‘nitrogen’ that wheat needs. Under wheat-pea rotation, not only will it not reduce wheat yield, but it will also increase wheat yield.
Rotating soybeans and millet is a bit unrealistic, and the growing seasons of the two are somewhat conflicting.
If you wait until the millet is harvested before planting beans, the most likely possibility is that the beans just bloomed and a frost came down...
It can be planted with rapeseed in turn~EbookFREE.me~ although they are not a good combination.
Although thinking this way, this year's soybeans did not form a pair with rapeseed. The main reason is that the number of soybeans is too small.
After a few hesitations, Han Cheng finally left five catties of soybeans to make tofu, and the rest of his brain was planted in the ground.
Instead of sowing seeds, they used deer-drawn carts to sow into the ground.
However, before planting, you need to pull out the wooden board blocking the eye of the columbine under the funnel to enlarge the eye.
Otherwise, a soybean that can be worth many grains will not leak.
Although I have adjusted the size of the warehouse as small as possible, and planted as little as possible, only two acres of land were planted for more than 30 catties of soybeans.
This is also due to the small soybean grains at this time. One is only about one-third the size of later soybean grains. If it is as large as later soybeans, I am afraid that the planting area will be less...
