After listening to Wang Shuangming's words, more than 20 students who have completed the first stage of their studies have been very entangled in their hearts, the benefits and treatment of this Huaxia Villa are really good, but their home still belongs to a certain industry in Ziguicheng, if they join the villa like this, it is equivalent to selling all their ancestral businesses to Huaxia Villa. For these people with strong traditional concepts, abandoning their ancestral business is a manifestation of unfilial piety, at least now psychologically they can't get over this hurdle.

Everyone discussed in a whisper for a while, and because the status of businessmen in this era was very low, they finally made a more cautious choice and chose to learn agricultural skills.

Wang Shuangming was slightly disappointed in his heart, because he knew that the current development of the villa was seriously constrained by the lack of population, and if he could supplement some of the population in this group of students, it would be of great help to the future of the villa. But the owner also said that those who join the villa cannot have any private property outside the villa, and whether or not to join the villa must be voluntary, so there is no better way for the time being, so let time prove that everyone's choice is wrong.

Wang Shuangming took the more than 20 students to Xiaobao to apply for temporary identity documents as a proof of their work in the villa, and then came to the front of the greenhouse.

Due to the warmer weather, you can also grow vegetables directly outside, so this greenhouse has temporarily lost the value of use, Wei Minsheng will use this greenhouse as a warehouse to store all kinds of equipment and materials, after all, it can shelter from the wind and rain.

Wang Shuangming said to Tie Zhuang and others: "Your previous agricultural cultivation method of 'slash-and-burn' is outdated, because the fertility in this land is limited, so you need to fallow for land cultivation. But the master gave us a book in which he described the conditions necessary for the grain to be abundant: water, fertilizer, gas, and heat. If we can control these four conditions, we can grow grain at any time and in any place. ”

"This greenhouse is a thing that can control the air and heat, so you can grow fresh vegetables in the winter. But the greenhouse is too small and the output is limited, so if you want to plant a large area, you still have to rely on the climate. Although we can't change the climate, we can change the three conditions of water, fertilizer and gas of the land, and get a large harvest when the climate is right. ”

Tie Zhuang said: "Teacher, we know that this grain needs to be watered, and if you want to grow vegetables well, you need to drench water, I think it is the 'fertilizer' you said, but what is this 'gas'?" ”

Wang Shuangming said: "Manure is only one of the 'fertilizers', and this 'qi' is the need for sufficient voids in the soil to facilitate the growth of grain. With these voids, water is able to carry its fertility deep into the earth, maintaining fertility and facilitating food absorption. ”

Tie Zhuang said: "Teacher, you are talking about ploughing, we have all done this. ”

Wang Shuangming said: "So, how many acres of land can you plow in a day?" ”

"If you have oxen, you can plow two acres of land a day."

Wang Shuangming said: "You should not have an iron plowshare, right? Otherwise, at least fifteen acres of land can be ploughed in a day. ”

"Teacher, do you have iron plowshares?"

"The host gave it to us if we needed it. But even with an iron ploughshare, it is useless, for we have only two oxen in the lodge at the moment. ”

"What about that? Without oxen, you can't plow the land, and if you can't plow the land, you can't grow grain. ”

Looking at Tie Zhuang's anxious appearance, Wang Shuangming said with a smile: "The kind of iron plough you said is useless to us, if you have the ability to plow fifteen acres of land on this day, how can a few people plant thousands of acres of land?" ”

"That's right! The owner of the village said that he has a few people here who have the skills to plant thousands of acres of land, what is it? ”

"I watched a small video from Xiaobao, which recorded a tractor in the world, which is said to be the owner, and created the best result of cultivating 4,800 acres of land 24 hours a day."

"Four thousand eight hundred acres?"

"I'm not wrong, it's 4,800 acres, and the power of this tractor is equivalent to the power of 500 horses at the same time, dragging 20 huge ploughshares made of steel, setting this record."

Tie Zhuang said, "Then why don't we use this tractor to plow the land?" ”

Wang Shuangming said: "Our villa is such a big place, a few back and forth will be over, and then this big guy will be put there?" Besides, the owner said that the thing wants to drink a kind of diesel, and the belly is very large, and the current diesel stock of the villa is small, and it can't afford to drink it. ”

Tie Zhuang was just excited, and listened to Wang Shuangming's words and went down again.

Wang Shuangming paused for a moment and said: "The master said, our villa is surrounded by this kind of hilly area, this kind of big guy is useless here, even if it is given to you, you have no way to start it, and the place where it works must be at least hundreds of thousands of acres of flat land." So, what you're going to learn now is a small ploughing machine. Although it is a small machine, one person can operate it and plough eighty or ninety acres of land in one day. ”

Wang Shuangming led everyone into the greenhouse and saw ten red machines neatly placed in the greenhouse.

The machine was more than a man tall, with a small pavilion on top and a lid in front and a dense network of curved blades underneath, the blade of which glowed with a dark glow that made people shudder.

Wang Shuangming looked at the manual of the rotary tiller and said to everyone: "This machine is called a rotary tiller, which can cultivate paddy fields, dry soil, land reclamation, weeding and grassland regeneration farming. Today we are mainly acquainted with the various parts of this machine and what they do. ”

According to the instructions, Wang Shuangming pointed to the blades and said to everyone: "Why is this machine called rotary tiller?" The main reason is these blades, each machine has 48 scimitars for ploughing the land, when they are ploughing, the machine drives these scimitars to rotate quickly, and the compacted land is connected to the weeds above, all of which are cut into pieces, so as to achieve the purpose of intensive ploughing. The land that has been ploughed with this machine is much better than ploughing with a plowshare. These broken weeds, the owner said, are also a kind of fertilizer after rotting. ”

"This is a trencher, which can open a trench 30 centimeters deep in the intensively cultivated land. In addition, this is a ridge shaper, which can be directly ridged after being installed on this rotary tiller, which is convenient for raising ground temperature, improving aeration and light conditions, and is also conducive to draining excess water and preventing some drought-loving grain crops from rotting roots. ”

"It's ......"

More than 20 students, under the leadership of Wang Shuangming, strangely surrounded the ten rotary tillers, touched here, looked there, and when they basically understood the role of various parts of the rotary tiller, it was almost dark. Wang Shuangming also ended the first day of mechanical teaching.
