However, although the Haikou is boasted, the construction principle of these parts is not a day to be able to integrate through, the structure of the fan car, for today's mountain and sea woodworking circles, is undoubtedly more complicated.

Danzhu held his breath, the words were all spoken, and his face was hung on the door, if he couldn't get it out tomorrow, would he still have his name?

The fan cart is a grain cleaning tool that removes chaff from the grain by creating air flow through the rotation of a fast fan wheel. The fan car is a speed-type centrifugal blower, and the work efficiency is much higher than that of the fan, dustpan, etc.

To be honest, I know every word in this sentence, but when combined together, there is a feeling of not knowing.....

The semi-open fan car clamps the fan wheel between the two box plates, and the shaft is located at the middle height or placed on the top of the box, and later there is a more advanced closed fan car, which seals the fan wheel in the box, and the air inlet is located in the shaft, and the air flow in the box conforms to the direction of centrifugal movement.....

Danzhu suddenly felt that this was a challenge for himself, and an opportunity to prove himself.

The reason why Emperor Fangxun doesn't like Danzhu to engage in carpentry work, especially shipbuilding, is because in Fang Xun's view, the sea is very big, the four seas are far away, no matter how big a flat boat is, it is just a humble insect for the waves in the sea, and a wave can overturn the ship, and the ships that can be made by the Great People's Kingdom are too small for the Central Plains.

What's the use? The land is so vast, the products are also abundant, and the things at the doorstep have not been dealt with.

The ship of the adult country capsized, and people could still swim to the edge of Dongyi with their bare hands, but the boat of the Central Plains overturned, so there was no then.

What are you doing running into the sea if you have nothing to do? Ships can already cross big rivers! No matter how you build it, it's just a big piece of wood, and what kind of technology does it have?

Flying gods don't need this thing, and people who can't fly don't need this thing, what's the point of existence of this thing?

But Danju doesn't think so, the sea is very interesting, and even in the middle of a big river, a strong ship, a ship with high maneuverability, can save a lot of people in time.

The fan car is also an agricultural instrument that appeared in the Western Han Dynasty.

"There's a bucket in there..... I'll take a look at ....."

Dan Zhu carefully studied the plank, and at the same time began to prepare the wood, he took out his own tools, and began to beat in his dwelling, of course, to his surprise, it was a thing in Yu Zai's hand.

This is something I haven't seen before, a new version of the ship's mussel sickle! This is the "saw"!?

Enhancement plus twenty?!

In Danzhu's opinion, this thing is no less than an epic artifact, as for the original stone mussel sickle, it is a silver scale cuirass bought for two gold coins, which used to be very good, but now it is a rotten thing.....

"Ah Hong... What are you doing....."

Akamatsuko saw a bamboo sign hanging on the door.

"Don't disturb the maker?"

Chi Songzi immediately understood that it was probably Yu Zai who showed Danzhu something, and the two of them had already come into contact with each other this morning.

In the tribe, grain is being transported to the barn, the barn is naturally built on the high ground, and the drainage ditch around it has long been done, there is a lot of time in the year, many things, do not need to be specially instructed by the concubine, the tribesmen after experiencing the convenience of the canal and ditch, will naturally be on the high ground, in important places, excavate these facilities, to prevent rainwater from soaking into the barn.

The tall barn is storing heavy grain, and those empty stone jars can't fit it, the old patriarch can't close his mouth with a smile, but he didn't expect that the thirty big stone jars that were chiseled before are now full, not to mention, there are more grains that are constantly stuffed in!

"The number of chisels is still small! I knew that I would have chiseled more, but unfortunately there is not enough time!"

"Take all the unfinished ones, shallower ones, shallower ones, and then chisel back!"

The old patriarch asked someone to bring in the wide stone jars that had not been finished and were still being chiseled, and the grain was poured into it, until in the end there was no choice but to make some soil and make it into an earthen platform, and hoard the animal skin bags full of grain on it.

And the largest jar is made of a few pieces of tortoise shell of the old turtle, which can hold at least 5,000 stone of grain!

The cultivated land of the Akakata clan is very large, most of it is composted, and for several months, everyone is working in the field, and the stone oxen pull the plough tirelessly, fortunately, so many factors add together to meet the work needs of so many cultivated land.

But even so, there is still a lot of land, which is widely harvested and thinly planted, because it is really impossible to take care of it, and when the hand is withdrawn, the best time for ploughing has passed, and it is difficult to get it again.

The tortoiseshell tank was full of grain from the land where the dolphins were plowed, and it was so full that it almost overflowed!

"More than 700 grains from one rice plant, and one plant of 1,000 grains from the land cultivated by the dolphins.....!

The old patriarch smacked his tongue!

Yu Zai once said to Huang Kanshan that the joint use of land, water, planting methods, and the yield of one mu may be able to appear in the situation of one grain and one thousand grains, and now, this scene has also been seen by the soldiers of tillers, elites, and reeds.

Bai Huangqi and Huang Liyin were huddled together, holding a big and fat rice plant, which they had specially kept after they picked it back from the field, and they were sending people back to the three mountains and four fields at this time.

"Tell Wu that the Chifang clan has really had a bumper harvest this year, and there are 1,300 grains on this rice plant!

That's almost fivefold!

And Lu also took a grain ear and asked the warriors of the Lu clan to bring it back to the field of Zaori, because the Lu clan is mainly fishing and hunting, and farming is used as an auxiliary, but the old wizard said that if it is a few years later, maybe he will have to give up fishing and hunting and change to farming, mainly depending on the flow of the water veins in the field of Zaori.

And now, following the Chifang clan, even if he turns fishing and hunting to farming, he will not appear in the situation where he has just changed, falling into a situation where he is inexperienced and has no harvest, or he has not enough to eat, causing the clan to complain.

In a word, firm the line, follow the red side, there is food, there is a bumper harvest.

"The red side divides acres of land, and the yield per mu is more than three stones, and the good land is above five stones, and the harvest is ...... There's almost nothing to be done!"

The warriors of the three mountains and four wilderness were in a very complicated mood when they took these slips and sent them back.

The acres and stones of the past dynasties are different, the most famous, one stone of the Tang Dynasty is equivalent to three stones of the Han Dynasty, and one and a half stones of millet in the early years of the Warring States Period, which is converted into nine buckets in later generations. In the land on the edge of Zhengguo Canal, one acre of land can harvest grain for one minute, and one bell is six stones and four buckets, which is equivalent to three stones, eight buckets and four liters per mu in later generations, which is why it is said that Zheng Guoqu, Dujiangyan, the land of Fat Bashu, and the country of Tianfu are cast.

Because of the proximity of the Chifang clan to Daze, the water of Yanzhize is not as deep and vast as Dongting Lake, it is a Daze that likes to be quiet and does not like to move, and the speed of building the canal this year is not fast, and there is no Zhengguo Canal, Dujiangyan such a big project.

However, some of the basic water conservancy facilities that should have been built, such as the waterwheel, have been built and added to the irrigation ranks early, although primitive and not durable, there is no need to worry, because the Akagatta clan now has a senior carpenter in the Central Plains.

The largest project is the dam, which Dayi participated in building.

However, because of the emergence of various farm tools, compost, manure and other methods, coupled with the effective avoidance of insect pests, and the blessing of the harvest beast, the Chifang clan still reached an incredible yield per mu in the mountains and seas.

The yield per mu is three stones, seven buckets and nine liters, which is the calculation of later generations, and has completely reached the level of the land of Bashu in the Qin State in the Warring States Period, and the level of the Qin State, even in the Western Han Dynasty and the Eastern Han Dynasty, is definitely among the best.

Next year, when the real canal is completed, this production will continue to increase!

Irrigated fields that are close to the water flow produce much more than unirrigated fields, generally about two to five times.

For Yu Zai, the yield per mu is two or three hundred catties, which is the scenery of the ancient prosperous times, this year is a surprise, although the yield per mu of later generations is six or seven hundred catties, and even the kilogram is calculated at every turn, and even more than three thousand catties, there is still a big gap....

However, a large area of land in the south has not been developed, and it is unimaginable that the land is abundant! Now it is just the beginning! Here, after all, there is a world of divine power and magic! The productive forces are not enough, and the divine power will make up for it!

And the land where the dolphins are cultivated has a yield of more than five stones per mu!

There are thousands of bells of rice in the ground!

And they believe that their own tribe that has learned the composting method before, this year, even if it is not as rich as the Chifang clan, it must be much better than in previous years!

"There is food in your hands, and you don't panic in your heart!"
