Chapter 553: Regrettable Rotation of Wheat and Beans
"Here, use a drill to hit this place and leave a mark."
Seeing the stunned expressions of Wu and others, Han Da Shenzi felt very relieved. He pretended to be calm and calm, and stretched out his hand to point at the mark he twisted out with a wooden stick.
This is the center of the circle. Make a mark at this time to save time and have to find the center of the circle again.
"Ah...good!"
I was staring at the simple compass in a daze on the wood. I was stunned for a moment and quickly used a drill to carve out an indelible mark.
Han Cheng used the same method to draw a circle on another stone slab with the same radius as the previous one.
This time, Han Cheng didn't need to say anything. The wood consciously used a hammer and a drill to carve out a shallow groove along the circle.
As for the simple compass, it is now in the wizard's hands.
Like a child who got a novel toy, he left circles of different sizes on the ground and never tired of it.
Shitou and Lame were two people who wanted to experience this wonderful tool with their own hands. After waiting for a while, Shitou still looked very interested, so he found a rope and a tree stick and joined in drawing circles on the ground.
Go in the circle.
Not long after, many circles of different sizes appeared on the ground of the Qingque tribe.
After these guys finished painting, they stood up and admired it. They said "hey hey hey" from time to time. They were obviously very satisfied with their masterpieces.
'These guys have never seen the world.' Han Cheng cursed in his heart.
'It's just a simple compass, is it so novel and interesting?'
Facts have proved that simple compasses are so fun.
Not long after the slander, Han Dashenzi also joined the group of people drawing circles on the ground.
Moreover, his technique of drawing circles with a simple compass is obviously much better than that of Wu, Shitou, and the lame ghosts.
The regular pentagonal pattern that appeared inside the circle, consisting of five semicircular arcs, amazed Wu and the others.
It turns out that in addition to drawing circles, this thing can also draw such complex and beautiful patterns. It's really amazing.
So, with the addition of Han Cheng, the addition of someone who was already a little reluctant to play immediately became more interested.
Such a simple and interesting tool soon spread among the Qingque tribe and was greatly welcomed by these primitive people who seriously lacked entertainment activities.
Especially the minors, each one was even more happy.
So in the following period, large and small circles could be seen everywhere inside and outside the Qingque tribe.
Even the top of the wall and the walls of the earthen kang have not been left alone, which can be described as extremely crazy.
Wearing a mask, the wood has been tinkling almost non-stop these days with hammers and iron drills.
As small pieces of stone peel off, a grindstone gradually takes shape.
Having learned the lesson of drawing a circle last time, Han Cheng did not let wood come to the places where small ditches were needed at the bottom of the stone mill. Instead, he used small wooden boards and small stones to draw lines of different lengths.
.
Then let the wood be cut 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 being dug out like this, the grooves become sparser as you go outside the stone mill, and the effect of grinding things is not very good, so I drew
It became a series of parallel lines.
Drawing parallel lines on a circle is not easy to draw, except of course the drawing method where the diameter is the middle line and then arranged in sequence on both sides.
The stone grinding effect produced by this painting method is not as good as the radial effect.
Han Cheng's drawing method is to divide the circle into several parts, and then draw parallel lines in these parts.
The lines between every section are parallel to each other.
In this way, there will be as many grooves as possible on the stone mill, and these grooves are not perpendicular to the edges of the stone mill, which can prevent beans from being poured into the grinding hole and running along the grooves before they are ground.
Embarrassing things happen.
It is foreseeable that the smart ancients who first invented the stone mill must not have invented a stone mill like this. Instead, they constantly discovered the shortcomings of the stone mill during use and tried every means to improve it.
Turn the stone into what it is now.
This is the benefit of being a time traveler. You can stand on the shoulders of giants and pick fruits, and directly absorb the wisdom that countless people have continuously perfected and passed down from generation to generation.
Han Cheng is luckier than the average time traveler because he is no stranger to stone mills, thanks to the fact that he had a millstone at home when he was a child.
There is a lot of work in turning peas into jelly and making flour paste noodles.
When Han Cheng drew the line and the wood began to jingle along the line, the rapeseed was ready to be harvested.
Harvesting of rapeseed should not wait until the rapeseed is fully ripe, but can be harvested when it is slightly yellow.
The reason for being so anxious is because every plant is a good mother and has a way to let its children leave its arms and survive independently.
Dandelion equipped its children with small umbrellas that could be carried away by a gust of wind. Xanthium equipped its children with armor with thin hooks so that when animals passed by, they could be carried to distant places.
As for pod-bearing plants such as rapeseed and beans, the method they borrow is sunlight.
When they are fully ripe, the pods can be easily split open, allowing their children to fall into the embrace of the soil.
Of course, Han Cheng didn't want to let such a thing happen. If the rapeseeds were allowed to enter the embrace of Mother Earth, their tribe's work would have been in vain this year.
However, compared to the past, this year's rapeseed harvest and subsequent processing were much faster and easier, thanks to the many extra slaves in the Qingque tribe.
With everyone working together, the rapeseed was harvested and processed within a few days.
Then, taking advantage of the good weather, the land where rapeseed was harvested was turned over and planted with late millet.
After millet was planted in the late 1990s, soybean planting was gradually put on the agenda.
It would be great if there was wheat.
Han Cheng thought with regret.
If there is wheat, you can rotate wheat and soybeans. The timing is just right and you can harvest two crops a year, which is great.
Moreover, soybean roots also collect a kind of fertilizer that wheat needs, which is called "nitrogen". Under wheat-bean rotation, not only will wheat production not be reduced, but it will also help increase wheat production.
It is somewhat unrealistic to plant soybeans and millet in rotation, as their growing seasons conflict somewhat.
If you wait until the millet is harvested before planting beans, the most likely possibility is that a frost will come as soon as the beans bloom...
You can plant it in rotation with rapeseed, although they are not a good combination.
Although I was thinking this way, this year's soybeans did not form a pair with rapeseed. The main reason is that the amount of soybeans is too small.
After some hesitation, Han Cheng finally left five kilograms of soybeans to make tofu, and planted the rest into the ground.
Instead of sowing seeds, they used deer-drawn columbians to sow the seeds into the ground.
However, before sowing, you need to pull out the wooden board blocking the bin eye under the columbine funnel to enlarge the bin eye.
Otherwise, one soybean, which is worth many grains of millet, will not leak out.
Although the barn openings have been made as small as possible and the seeds sown as little as possible, more than 30 kilograms of soybeans have only been planted on two acres of land.
This is also due to the small size of the soybeans at this time. One is only about one-third the size of the soybeans of later generations. If the soybeans are as big as the soybeans of later generations, I am afraid that the planting area will be even less...
