When planting cotton seeds, Yang Yue still came out. Cultivating cotton is a technical job to a certain extent. Ordinary farmers will inevitably have some problems when planting this. In order to ensure the germination rate, Yang Yue has always followed. 2-3 cotton seeds can be planted in each petri dish. At Yang Yuanzhao's request, the final choice was two cotton seeds. After planting, Yang Yue even put a large amount of charcoal fire in a specific greenhouse to increase a certain carbon dioxide content.

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

After inspecting several specific greenhouses, Yang Yue returned to the greenhouse he had specially opened up. Some local seeds were planted here, as well as seeds collected from Shanghai. There is another study in the United States, which happened to be carried out here.

Just as he was about to enter, a loud and loud sound came from the distance. Yang Yue looked back and saw that a huge creature appeared there on the open space hundreds of meters away from his greenhouse.

It looks very strange. It is made of steel all over the body. Below are steel tracks. The upper floor building is square and seems to be using some kind of internal combustion engine. Huge black smoke permeates this space.

"Tractor!" Yang Yue was stunned for a moment. While on the road, Yang Yuanzhao once mentioned that he would use machines to help with agriculture.

Large-scale mechanized production is also an emerging industry in the United States. Some internal combustion machines are used in agriculture and have achieved some results. Tractors were originally steamed and were only changed to internal combustion engines a few years ago. However, their power is small, but they have shown vigorous vitality. However, the one produced by Yang Yuanzhao is too big.

After Yang Yuanzhao returned to Baotou, in addition to helping with cotton planting, he spent the rest of his time developing tractors. On the way to Shanghai, Yang Yuanzhao had already figured out many details and made a large number of equipment, but there was no experiment.

The existence of all-in-one machines and any experiments came very quickly. In just less than 10 days, Yang Yuanzhao made many attempts, but only the configuration of tracks was carried out hundreds of times. Through continuous attempts, Yang Yuanzhao's tractor has begun to take shape.

Now, after summarizing the experience and lessons, Yang Yuanzhao finally came up with such a prototype, which did not install many functions, but had the most basic plowing function and driving function. However, it is enough to be used for farming in cotton fields.

"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 tractors with large tonnages can easily compact the land, which is not conducive to the cultivation of land. Farmland is originally soft, and the tonnage of large-horsepower engines will be too large to bear. However, some small-horsepower tractors have single functions and are prone to problems. In terms of use, they are not as good as flexible animal power. Except for a few researchers and specific places, there are very few tractors in the United States.

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

Yang Yue keenly grasped the benefits of this kind of thing. After studying modern physics, he knew very well that the weight of the unit would be spread to the contact surface. American tractors were considering how to increase the wheel area. However, no matter how they increased, the area of ​​the wheel was very limited and it was impossible to significantly increase the engine power. However, Yang Yuanzhao actually used tracks with dozens of square meters of tracks, which evenly distributed the pressure brought by the huge volume. In this way, the pressure per unit area was even smaller than the wheels. From the situation of this field, it can be seen that the soft soil layer did not sink in front of the tractors that were all steel, and the tractor stopped steadily on the land.

"Can you start running?"

Yang Yuanzhao nodded and said, "Yes!"

This tractor has been modified dozens of times in a row. On the steel, more steel from later generations are used. Compared with this era, it is not only much lighter in weight, but also more sturdy. It has a certain off-road capability. As long as the gullies are not more than 2 meters wide and some steps of tens of centimeters high and low, it can be easily traveled, suitable for more complex environments in the wild.

The performance of the tractor is gradually stable, but it is only functional. It needs to be studied. At present, what Yang Yuanzhao can do is just a simple plow, with a format of about 4 meters. He did not choose the disc plows of later generations because Yang Yuanzhao was not familiar with them and used the most classic plows, with more than ten in a row, because all of them were used in later generations of high-hard alloys, which were not only extremely sharp, but also extremely strong.

Tractors are a new thing in Baotou, and even Yang Yuanzhao became interested. Under Yang Yuanzhao's guidance, he quickly learned to drive and drove on about 3 acres of wasteland. The speed was neither fast nor slow. When the control button was pressed, the plow was placed in the land, and the controlled 50-75 cm deep plow began.

The strong power of BMW 999 is undoubtedly revealed here. The tractor drove through this wasteland at a speed of about 10 kilometers per hour. The barren land on the surface was directly cut open and replaced by deep soil. This area is not cooked and the soil is poor. However, after deep plowing, when the deep plowing out, it actually has a trace of fertility. The old farmer watching the fun next to him grabbed a handful of soil, smelled it, and then exclaimed: "Good thing, just ploughing it so deeply, with a yield of dozens of kilograms, it should be fine!"

Farmers rely on the weather for their own income. What they pay more attention to is the yield of grain and crops. Although these farmers have joined the Baoqing Company, they still do farm work and amazed at the tractor.

I don’t know when Wu Guangren also came here. As a landlord who plays hundreds of hectares of land, Wu Guangren attaches more importance to the speed of the tractor and plowing the land. In farm work, he is the most labor-intensive and labor-intensive. Even as a landlord, he has dozens of livestock, but when he is a farming season, he still has to hire odd workers. Otherwise, he will not be able to catch up with the farming season. The strange machine in front of him, with a huge roar and a blue smoke, is it better than a large livestock. How long is it to be completed in three acres of wasteland of land. If you really need to cultivate land for a day, you may not have a hundred acres. If you have more of such a guy, it is not the most suitable for landlords who own a lot of land.

Yang Yuanzhao made the final adjustment to the tractor, mainly to adjust the efficiency of the cultivated land. The typical plow speed is slightly worse than the disc plow, but the fixed depth can continue to increase. If one acre of land is deeply plowed and dried, it can increase the fertility of the land and improve the efficiency of the land use. The most important thing is to reduce pests and diseases. The sun's ultraviolet rays will kill some insect eggs that are turned out. This is the most important effect of deep plowing.

Finally, Yang Yuanzhao finished the adjustment. The tractor was basically finalized, and even the plow was determined. Next, it was to increase the functionality, harvesting and pelleting. Yang Yuanzhao basically had some ideas, mainly to design harvesting pendants based on the appearance of later generations. However, Yang Yuanzhao could not use a combine harvester directly for the time being. He did not understand the combine harvester particularly. Fortunately, if mechanized harvesting, as long as the wheat was cut, he could design a side hanger, and only cut it, and then manually take it to a special threshing machine for threshing. This added a process, but the design difficulty was not known how much it was reduced.
