When planting cotton seeds, Yang Yue still came out, cultivating cotton, a certain process dù above, is a technical work, this ordinary farmer, planting, it is inevitable that there will be some problems, in order to ensure the germination rate, Yang Yue has always followed, in each petri dish, you can plant 2-3 cotton seeds, under the requirements of Yang Yuanzhao, the final choice is two cotton seeds, when planted, Yang Yue will even put a large amount of charcoal fire in a specific greenhouse, increase a certain amount of carbon dioxide content.

For only 10 days, Yang Yue has been observing these cotton seeds, until a large number of cotton seeds have sprouted, and then he relaxed.

Yang Yue finished inspecting several specific greenhouses, and returned to the greenhouse he had specially opened up, where some local seeds were planted, as well as seeds collected from Shanghai, and there was a research in the United States, which happened to be carried out here.

Just as he was about to enter, there was a sudden sound in the distance, and Yang Yue looked back to see that just a few hundred meters away from his greenhouse, a behemoth appeared there.

It looks very strange, the whole body is made of steel, the bottom is a steel track, the upper building is square, it seems to use some kind of internal combustion engine, and huge black smoke fills this space.

"Tractor!" Yang Yue was stunned for a moment, when he was on the road, Yang Yuanzhao once mentioned that he would help agriculture with the help of the machine.

Large-scale production, in the United States, is also a rising industry, some internal combustion engines are used in agriculture, has played some effect, the tractor was originally steamed, a few years ago, it was changed to an internal combustion engine, but the power is smaller, but it has shown vigorous vitality, but at the moment, Yang Yuanzhao's production of zuò this, is inevitably too big.

After Yang Yuanzhao returned to Baotou, in addition to helping to plant cotton, the rest of the time has been developing tractors, and on the way back and forth to Shanghai, Yang Yuanzhao has figured out a lot of details, and made a large number of equipment, but it lacks real yàn.

In less than 10 days, Yang Yuanzhao has made a lot of attempts, just the configuration of the crawler, hundreds of times, in continuous attempts, Yang Yuanzhao's tractor has begun to take shape.

No, after summing up the lessons learned, Yang Yuanzhao finally came up with such a prototype, which did not install many functions, but only had the most basic plowing function and driving function, but it was enough for cotton field cultivation.

"Yuan Zhao, is this what you call a tractor?" Yang Yue walked to the front of the tractor and looked at the behemoth curiously.

As an agricultural scientist, Yang Yue has some understanding of tractors, specifically, in the United States, tractors have not completely replaced animal power, the reason is that the tonnage of large tractors, it is easy to compact the land, which is not conducive to the cultivation of the land, farmland is relatively soft, the tonnage of the high-horsepower engine, will be too large to bear the Cheng dù, but some small-horsepower tractors, single function, and easy to have problems, in terms of usability, but not as good as flexible animal power, Except for a few researchers and specific places in the United States, very few tractors are used.

Yang Yue's eyes fell directly on the chassis of the tractor.

Crawler, Yang Yue is very keen to grasp the benefits of this kind of thing, he has studied modern physics, he is very clear, the weight of the unit, will be evenly spread to the contact surface, American tractors are considering, how to increase the area of the wheel, but no matter how to increase, the area of the wheel is very limited, can not greatly increase the power of the engine, but Yang Yuanzhao actually pioneered the use of the track, the whole enough to have dozens of square meters of track, evenly distributed the pressure brought by the huge volume, so the pressure per unit area, Even smaller than the wheels, it can be seen from the situation of this field that the soft soil layer did not sink in front of the tractor, which was all steel, and the tractor stopped steadily on the ground.

"Can you do it?"

Yang Yuanzhao nodded and said, "Yes!" ”

This tractor has been modified dozens of times in a row of finished products, steel, more use of later generations of steel, compared to this era, not only lighter weight, but also more solid, crawler, has a certain off-road ability, as long as not more than 2 meters wide ravine, there are some tens of centimeters high and low steps, can be easily traveled, suitable for the field more complex environment.

At present, what Yang Yuanzhao can do is just a simple plow, almost 4 meters long, and there is no choice of disc plough in later generations, because Yang Yuanzhao is not familiar with them, it is the most classic plow, more than ten in a row, because all are used in the later generations of high cemented alloy, not only sharp and abnormal, but also extremely strong.

Tractor, in Baotou, is a new thing, even Yang Yuanzhao has an interest, under the guidance of Yang Yuanzhao, quickly learned to drive, driving on the 3 acres of wasteland, the speed is not fast or slow, when the control button is pressed, the row of plows is placed in the land, and the 50-75 cm deep ploughing of the control zhì begins.

BMW 999 strong power, here is undoubtedly shown, the tractor at a speed of about 10 kilometers per hour, driving through this wasteland, the surface of the barren land is directly divided, replaced by a deep layer of soil, this piece is not familiar land, the soil is poor, but after deep ploughing, when the deep soil is turned out, there is actually a trace of fertility, next to the lively old farmer, grabbed a handful of soil, smelled it, and then exclaimed: "Good things, just so deep ploughing, the yield is more than dozens of catties, It should be no problem! ”

Farmers rely on the weather for food, and they pay more attention to the output of grain and crops, although these farmers have entered the reclamation company, they still do farm work, looking at the tractor and marveling.

I don't know when, Wu Guangren also came here, as a role in hundreds of acres of land of large land, Wu Guangren is more important is the speed of the tractor, ploughing, in the farm work, belongs to the most labor-intensive, the most labor-intensive, even as a big landlord, he has dozens of head of livestock, but when it comes to the season of ploughing, it is also necessary to hire odd workers, otherwise, it will not be able to catch up with the agricultural time, this strange machine in front of him, a huge roar, plus green smoke, but than what large livestock, I don't know how much stronger, three acres of wasteland, how long has it been, it will be completed, if you really want to plough the land for a day, I'm afraid there are 100 acres, such guys, if there are a few, for them landlords who have a lot of land, isn't it the most suitable.

Yang Yuanzhao made the final adjustment to the tractor, mainly to adjust the efficiency of cultivated land, the typical plough speed is a little worse than the disc plow, but the depth can continue to increase, one acre of land, if deep ploughing and drying, can increase the fertility of the land, improve the efficiency of land use, the most important thing is to reduce pests and diseases, the sun ultraviolet rays, will kill some eggs that are turned out, this is the most important effect of deep ploughing.

Finally, Yang Yuanzhao ended the adjustment, this tractor has been basically finalized, even the plow has been determined, next, is the increase in functionality, harvesting and granulation, Yang Yuanzhao basically has some ideas, mainly according to the appearance of later generations, designed a harvesting pendant, but, for the time being, Yang Yuanzhao is not able to directly use the combine harvester, he is not particularly clear about the combine harvester, fortunately, mechanized harvesting, as long as the wheat is cut down, he can design a side hanging, only use to cut, Then it is manually taken to a special threshing machine for threshing, which has one more process, but the difficulty of the design, I don't know how much it is reduced.

Together with Yang Yue, he walked to the edge of the field, and Wu Guangren, who was still waiting, took the initiative to catch up and asked: "Yuan Zhao, I don't know if this machine qì, in the end, in the end, in the end, ......"
