"By the way, Oishi, how do you harvest the wheat every year?"

Thinking that the wheat was about to ripen, Chen Xuhou suddenly thought of a big problem.

Chen Xu remembered that wheat was harvested in the countryside with a small agricultural harvester, and an acre of land was cut in half an hour, and threshing and bagging were completed by the way, but now it was the Qin Dynasty more than 2,000 years ago, not to mention the harvester, and it seems that the meniscus used in later generations has not yet been invented.

Niu Dashi also knew that Chen Xu didn't remember much since he woke up, so he explained without any surprise: "We cut off the ears of wheat, took them home to dry for a day or two, and then beat them several times with a flail or bamboo pole, and then put them in a rattan basket with eyes and shook the wheat and fell out." ”

Chen Xu nodded, this is not much different from later generations, the wheat after the harvester threshing has to be dried and sieved when it is brought home, but only cutting the ears of wheat makes him a little incomprehensible, so he asked curiously: "What should I do with the wheat stalks after cutting the ears of wheat?" ”

"What's the use of wheat stalks, if you like it, cut some and dry it and cook it on the fire, and then set fire to cook the rest when it comes to winter, and then plant wheat!" Niu Dashi shrugged.

"There are no cattle in the village, how can you plow the land?"

"We don't plow the land, we use a hoe to dig a hole and plant wheat!"

it! Chen Xu was directly stunned.

Although he has traveled over for more than 20 days, he has never asked about farming, and the crops in the field have always been taken care of by Chen Jiang's family with Xing'er, so he doesn't know how the village grows crops.

There are no cattle, no plows, the land can not be deeply cultivated so that the nutrients of the soil can be rotated, and the seeds can only be planted by digging a small pit on it year after year, and the weeds in the ground cannot be destroyed and removed, resulting in wild grasses rising wildly every year, which leads to the crops without nutrients and cannot grow well at all.

And he finally understood why a person can plant dozens of acres or hundreds of acres of land at this time, this primitive and extensive planting method is completely similar to playing around, using the method of kitten, far less than the harvest of deep ploughing and planting three or five acres of fields.

However, in this era, there were fewer people and more land, and there was a lack of large livestock and large agricultural tools, so farmers had to resort to this primitive cultivation method.

It seems that in order to change this pattern of farming, you have to buy a cow and then make large farm tools such as a plow.

Cattle were rare and valuable in this era, and even in the later generations until the 21st century, cattle were still an important pillar of peasant families in the mountains, and almost all dynasties for more than 2,000 years had regulations that it was illegal to kill cattle.

Chen Xu has been to Qinghe Town twice, and he has only seen a few cows pulling carts in the town, so it seems that it must be very difficult to get a cow.

As for the plough and harrow, these farm tools are relatively simple.

Chen Xu remembered that when he was a child, he had one at home, and it was made of iron, and he could roughly make it out of wood according to his memory, but I don't know if it is good or not.

But it's too early to think about these things.

And he is not interested in farming, as long as he earns enough money, even in the famine years, he can eat the delicacies of the mountains and the sea.

But it's still okay to be a landlord!

Looking at a small flat field with an area of only 30 square meters in front of the new house, Chen Xu estimated that if all the ears of wheat in the field were harvested, this place would be completely insufficient, but the cost of expanding and leveling a larger area to dry wheat was too great, and it would take two or three days to level the site alone, and it would take two or three days to tamp the ground with a wooden pestle and planks after sprinkling water, and this work would take at least two or three days, and it would take several days for the ground to be completely dried, and it was estimated that it would be too late.

What to do?

Although he didn't know how Chen Jiang had done it with himself and Xing'er before, but now that he had traveled through two thousand years of time and space, and if he had to use this lowest-level and most tiring method to do it, he would obviously lower his score in the filing of the Time and Space Travel Administration.

Every time-traveler is an absolute darling of this era.

You need to stand at the top of the highest tide with the most powerful and mighty posture, brave the wind and pee, and finally become a peerless great man who makes holes in the sky.

Traversers, obscurity is not allowed.

This is a phrase engraved in the entrance hall of the Time Travel Authority.

Therefore, after Chen Xu leveled a piece of sand on the ground with his bare feet, he picked up a thin bamboo stick and began to draw.

Thresher, this is the first farm tool that Chen Xu is going to design.

There are two kinds of threshers he has seen, one is the one on the harvester, which needs to be driven by a tractor or motor, and a smaller threshing equipment, which is stepped on, like an old-fashioned sewing machine, when stepping on the connecting rod, the connecting rod will drive the spindle to rotate, and then put the end of the wheat straw with the ear into the mouth, and some staggered and convex steel bars on the spindle will twist the head of the ear, and the wheat will fall off, and then fall down from the outlet.

At present, there are definitely no connecting rods and belts, but they can be made into hand-cranked, and in this era, only labor is the least valuable, and manpower is not valuable.

After drawing, wiping and painting, and repeating it many times, Chen Xu roughly froze the design.

The design is very rough, and many places are completely made up by imagination, but as a person who has seen thousands of years of civilization in later generations, there is no problem with this simple machine in principle, and the biggest problem is actually production, in this era when there are no chainsaws, no lathes, and even the simplest and most primitive carpenter's tools are not complete, it is not an ordinary difficulty to make a designed thing.

But Chen Xu still felt that he could give it a try, and after the sketch was finalized, all parts were marked with numbers.

"Brother Xu, what are you painting?" Niu Dashi saw Chen Xu squatting on the ground again to write and paint, so he stood quietly behind him and looked confused.

Since Chen Xu woke up, he found that he couldn't understand his eldest brother more and more.

Not only has his temperament and temperament all changed, but the things he has done are even more incomprehensible, he will squat on the ground at every turn to write and draw, and at the same time he will recite words in his mouth as if he has been evil.

"This is called a threshing machine, which is used to thresh the wheat, and if it is done, it can be harvested and threshed in the field, and then the wheat can be picked back and dried." Chen Xu explained.

"You're saying this thing can get the wheat off the ears of wheat?" Niu Dashi asked excitedly.

"Well, the principle should be fine, but we will only know the effect until we have to do it, so let's go and see a tree first!" Chen Xu dropped the bamboo stick and stood up, took a saw and axe and set off, and Niu Dashi hurriedly followed.
