Not far from the village, there is the villagers' fields, which can be said to stretch from the edge of the village to the distance.

Chonghe Village is located in a mountainous area, surrounded by high and low hills, and the villagers' fields are terraced fields carved out of various hillsides.

Unlike the large areas of farmland in the plains, the farmland in the hilly areas follows the topography and has irregular shapes.

Where there is a large emptiness, the area of the land is larger, and the higher it goes, the smaller the area. Layer by layer, like a ladder. If you look down from above, the large and small fields seem to be patches of the earth, which is quite interesting.

Qi Jia and Qiu Niang shuttled on the patch of the earth, and the fun was not a little, but the taste was a little sad.

"Oh my God!" Qiu Niang, as a middle-aged woman who is not full of physical strength, is already out of breath after climbing a few small hills.

"With such terrain and farmland like this, irrigation is a troublesome matter!"

That's right! If the villagers are irrigated, they really have to carry water.

One pole, two buckets, swaying, picked into the ground, how much can be watered?

Therefore, that is, the diligent people are willing to make efforts to carry water and cultivate the land, so that the crops can keep up with the water. If you don't carry water, you have to rely on the sky for food.

Therefore, the field below is good land, easy to cultivate, and watered in time; The higher you go, the harder it is to plant.

The Qi family's several pieces of land are not good land, halfway up the mountain, but Father Qi and Qi Luan are very diligent, try to pick up water and fertilizer, but also serve the crops well.

"This land is thin!"

Not only their own land, but also other people's homes, everyone's is the same! Qiu Niang has been all the way, and the biggest emotion is this.

Hilly land is not fertile soil, and it is used to grow crops, which has a natural disadvantage.

The sparse wheat fields and scattered sorghum show that the yield is by no means high.

"The soil is not good, you see, this gravel land is not very suitable for growing wheat, it is less fertile and has less water." Qiu Niang was pulling the soil while explaining to Qi Jia.

"This kind of soil is more suitable for peanuts, and Daddy is right to grow peanuts. However, the fertility of this land is really not good, even if it is a peanut, the yield will not be high. What's more, there is no chemical fertilizer in this world, so we can only rely on accumulating soil fertilizer. Qi Jia also expressed his opinion.

"You can also farm?" Qiu Niang was surprised when she heard this, "Aren't you a space soldier?" ”

"Space Marines are also versatile! You can't just fight, you have to keep up with this rescue, medicine, and botany, otherwise you have to come to a strange planet, how to solve the problem of survival?

What's more, in some sci-fi worlds, there are interstellar farming missions! ”

I see!

Indeed, the division of the world is very general, and when doing tasks, in the same section, there may be different emphases, and the development of the world will be different.

Qiu Niang gave a thumbs up: "It's much easier for me to know how to farm, we have a common language." ”

"Sir, are we going to break through from farming?"

Qiu Niang found a stone to sit on, and looked at the surrounding farmland to meditate while resting, as if she was an old farmer thinking about the harvest, but she was missing a cigarette pouch in her hand.

"It's hard! This level is not a star and a half.

In the past, I have traveled through many classical worlds, and each world has a different level of agriculture. The higher ones have mastered water conservancy irrigation, multiple planting and intercropping; The lower ones are still in the primitive fire cultivation and water rake.

The world we live in right now is one of the lower averages.

You see, they know how to use the terrain, and with the concept of terraces, this is progress. However, judging from their mastery of crops, the cultivation technology is not mature.

Oh yes, look at the farming tools at home, and you will know the level of agriculture. ”

Qi Jia listened to Qiu Niang's analysis, and also felt that this was indeed the case.

It is not easy to farm, and it is not easy to make a fortune by farming······

"Sir, I think it's okay for us to think differently. Their productivity is low, and if they farm like this, it can be seen that there is still a lot of room for growth. ”

Qi Jia's aura flashed, and his big eyes flashed with brilliance again:

"We can introduce a lot of advanced agricultural tools, such as mechanical ploughing, motor pumping, to improve their labor efficiency! It can also produce fertilizers and increase yields! ”

The sale of every machine and the distribution of every bag of fertilizer may be the source of their own money!

"Your machine is powered by energy, right? Diesel or Electric? Do you have to solve the energy problem first?

In addition, do the complex parts in your machine need to be produced together with various machine tools? Do you have a forging fitter?

In other words, can the steel used to make the machine be made at the level of forging in the world today? ”

"Ah, this······ I didn't even think about it! Qi Jia was a little dumbfounded.

In the past, she traveled through the science fiction world, the level of science and technology, at least the beginning of the spaceship-type, accustomed to living in the high-tech era, suddenly forgot that every kind of scientific and technological products that can bring convenience are supported by a huge scientific and technological chain.

Now, the world is very backward, transportation is basically by walking, communication is basically by roaring, and public security is basically by dogs. You're going to build a sophisticated, state-of-the-art machine in such a world?

"I'm so hard!" Qi Jia supports the forehead.

"That's a difference of more than 2,000 years in productivity!" Qiu Niang said softly.

"However, you can't back down because it's difficult!" Qi Jia was unconvinced, "Improve, you must improve!" ”

Qi Jia squatted beside Qiu Niang, took Qiu Niang's hand and shook it: "Mother, tell me about the farm tools in the world where your level is higher?" I can refine the design and make a production tool that fits the world! ”

Qiu Niang was very satisfied with Qi Jia's comprehension: "No problem! And there's good news!

There are many things that are the same in the parallel world, and there are several high-yield general-purpose crops that often appear in this three-dimensional classical world, which can greatly solve the problem of human rations.

Along the way, I saw that there were no crops suitable for growing here, probably because the people here had not yet discovered them. ”

"Ah, really?" Qi Jia was very surprised: "Which kinds?" ”

"Potatoes, sweet potatoes, corn."

"Ah, I also know that I have encountered them in some mission worlds, and these kinds of crops are indeed high yields, and they are the best crops in some interstellar eras." Qi Jia was even happier, she happened to grow these things.

"It's just that these things are not easy to come by. In many of the classical world, these three things were often imported and could only be obtained with the discovery of the New World or exchanges across continents. "Qiu Niang has traveled through many worlds, and she often encounters this situation.

"I look at the world we live in, I'm afraid there are no such crops in Da Chuli, otherwise the advantages are so obvious, they will definitely be widely planted. But now you see, is there a shadow of them? ”

"That's miserable, could it be that I have to cross the mountains and the sea to find them?" Qi Jia hugged her head and sighed.

I can't leave my brother!

"Oops, it's broken, I forgot something important!" Qi Jia suddenly remembered.
