Another world conquest manual

In the breeding center, Xiang Hua introduced Lin Li:

"Academician Lin, you may not know much about it. In our country, rice is divided into three types: heavy panicle type, multiple panicle type and large panicle type.

Among them, the heavy-ear type is suitable for hybrid breeding. Although the large-ear type rice also has relevant technical reserves, it is actually mostly used in corn and wheat.

As for the multi-spike type, due to poor lodging resistance, both the market and scientific research are somewhat out of touch.

There are definitely still people of this type, but the retention rate in the industry is no longer very high. "

Seeing Lin Li nodding to indicate that he understood, Xiang Hua broke off an ear of rice and handed it to him, and continued:

“There are currently twenty-three known rice varieties in the Mojie world, and they are basically multi-spike type.

The one I have is unhybridized No. 4 rice seed, which has low yield, shriveled fruits, and poor resistance to lodging and disease.

The only advantage is that it matures early. Even without the assistance of Spirit Butterfly, its maturity period can reach about 75 days. "

Lin Li took the ear of rice and squeezed it with his fingers.

As a result, as soon as he exerted a little force with his fingers, the tassels on the rice ears came off and fell lightly on the pair of Hongxing Erke he was wearing.

Lin Li's brows immediately frowned.

Regardless of the fact that he is now the top biological authority in the country, living with standard academician treatment, and even equipped with a dedicated assistant and laboratory, his legitimate income can reach tens of millions a year even if he doesn't use his brain.

But when he was a child, Lin Li was a real rural boy.

He was born in the land of Ganpo in the 1970s. During his childhood, he traveled up mountains and down rivers, carried firewood on his back and planted rice.

There is definitely happiness, but more of it is the bitterness of life.

Although you can no longer see the traces of the rural boy from the past on Lin Li's face, his accent that might have evolved into "Biao Guo Wo Rong is here" was corrected when he went to the north to study at university.

But some basic agricultural knowledge is still indelible in his memory.

It's like a bicycle. Even if you haven't touched the handlebars for more than ten years, you can still ride smoothly and fast as long as you pedal with your left foot.

It has become an instinct.

Therefore, the moment he touched the ears of rice, Lin Li subconsciously made a judgment in his mind:

This kind of rice ear yield is definitely not high, and it is very easy to lodging.

The so-called lodging refers to the phenomenon that crops that grow upright become skewed in patches or even fall to the ground due to natural factors such as wind, hail, heavy rain, or external forces.

Lodging will reduce crop yield and quality and make harvesting difficult.

When crops such as wheat and rice are seriously lodging, their yields will be seriously affected and may even lead to harvest failure.

No matter how you look at it, this No. 4 rice seed is garbage among garbage.

And it is this kind of rice seed that can be called waste, but it is one of the most common crops in the Great Mo World.

This shows how serious the food shortage in the Great Mo Realm is.

Seeing that Lin Li's expression was a little complicated, Xiang Hua continued:

"Academician Lin, the lowest output value of No. 4 rice seed is more than 20 kilograms per acre, the highest is about 100 kilograms, and the average yield is about 40 to 50 kilograms.

In addition, even for rice seeds with a maturity period of 120-140 days that have been abandoned by farmers in Da Mojie, the yield is only about 150 kilograms at most, with an average of just over 80 kilograms. "

Students who are more familiar with the concept of land should know this.

Land is generally divided into high-yield fields and low-yield fields, and the concepts of the two can be understood literally.

And even if it is the high-yielding field output that Xiang Hua said, it is not enough when compared with the local area.

The "not enough" here refers not only to modern times, but also to ancient times.

Let’s first talk about the local ancient situation.

"Guanzi Qingchongjia" records the rice yield in the Spring and Autumn Period:

"If you plow a hundred acres all year round, you will only get twenty minutes of harvest from that hundred acres."

That is to say, if a family cultivates 100 acres of land a year, the total income will not exceed 20 acres.

The acres in the Spring and Autumn and Warring States periods were very small. Three and a half acres is equivalent to one acres today. The hundred acres mentioned by Guanzi were actually only 30 acres.

"Zhong" is a unit of capacity, which can hold 130 liters and 80 kilograms of rice. 20 Zhong is 1,600 kilograms.

The total output of 30 acres of cultivated land is 1,600 kilograms, with an average yield of 53 kilograms per mu.

This is almost the average during the Warring States Period.

In addition to Guanzi, Ji Kang's "On Health Preservation" records the output during the Wei and Jin Dynasties:

“Ten dendrobiums per acre is called fertile farmland, and this is the common name in the world.”

In other words, if one acre of land can harvest 10 bushels of grain, it is considered a high yield.

The acres in the Wei and Jin Dynasties were larger than those in the Spring and Autumn Period and the Warring States Period, about one and a half acres equal to one market acres today.

At that time, the harvest of 10 dendrobium per mu was equivalent to the harvest of 15 dendrobium per mu.

How much was 15 dendrobium at that time? ——The current equivalent is 150 liters, which can hold 90 kilograms of rice.

In other words, high-yielding fields during the Wei and Jin Dynasties could achieve a yield of 90 kilograms per mu.

I won’t go into details later, but just take the paper “A Study on Rice Yield per Mu in the Taihu Lake Area during the Song, Ming and Qing Dynasties” published by Mr. Min Zongdian of the Agricultural Heritage Research Office as an example, which records the average mu of rice in the Taihu Lake Basin in the four dynasties of Tang, Song, Ming and Qing Dynasties. Produce:

In the Tang Dynasty, the yield per mu was 138 kilograms;

In the Song Dynasty, the yield per mu was 225 kilograms;

In the Ming Dynasty, the yield per mu was 333 kilograms;

In the Qing Dynasty, the yield per mu was 278 kilograms.

Of course.

The main food in each dynasty is not necessarily rice, so there is definitely an error in the accuracy of the yield of rice varieties.

But this kind of comparison itself is not expected to compare with single digits. Direct comparison with hundreds of digits is enough.

If the basis of people's livelihood in Da Mojie is compared to the Qin and Han Dynasties, then its food level may only reach the level of the Spring and Autumn Period.

As for the current local food production, it is even more terrifying.

That kind of super hybrid rice is a reserve grain, so let’s not compare it for now. Even if it is just ordinary high-yielding edible rice, the yield per mu can easily reach 800-1000 kilograms.

In other words, the local yield of one acre of land can achieve the planting effect of 40 acres of large Mojie land.

Such a comparison can show how poor and lagging the planting industry in the Great Mo Realm is.

In stark contrast to the food output, is the population of the Great Mo Realm.

The population base of the Great Mo Realm is actually not large. Although the size of a city is limited, don't forget that the territory of the Great Mo Realm is actually very vast.

For example, the radiation range of Ziqiong City is almost a circle with a radius of one thousand kilometers.

On the mainland, that is, from the Magic City to Tianfu. Ahem, the straight-line distance from Tianfu City is the diameter of a circle.

And this kind of territory is only one-sixth of the Southern Territory.

The Great Mo Realm is not a centralized country, so if you really want to benchmark, you should benchmark it at the "Earth" level.

Therefore, it is not surprising that Da Mo has a large territory and a large population.

Under such circumstances, the planting industry is extremely underdeveloped, and one can imagine the difficulty of basic people's livelihood throughout the world.

Xiang Hua then took Lin Li to another area, which was only separated by a wall from the No. 4 rice seed.

However, what is completely different from the neighbor next door is that the rice ears in this area are much stronger - as long as they are not Neon's group of blind and disabled referees, most people can easily tell this.

After arriving here, Lin Li looked at Xiang Hua with some understanding:

"Researcher Xiang, could this be it?"

Xiang Hua nodded towards him, confirming Lin Li's guess:

"Yes, this is the first-generation hybrid rice we cultivated in the Mojie, Houji No. 1.

Now the production capacity of Houji No. 1 per mu has reached more than 200 kilograms. Although the gap is still very obvious compared with the mainland, it has somewhat caught up with the level of the ancient heyday dynasty. "

Lin Li nodded approvingly, then showed a hint of curiosity on his face and asked:

"Researcher Xiang, how did you cultivate this kind of rice?"

Xiang Hua smiled. He had prepared relevant drafts before coming and introduced:

"Since the cycle of day and night in the Great Mo Realm is 168 hours, many crops in the Great Mo Realm have characteristics corresponding to this situation. It is natural selection.

Because of this, they cannot be cross-grafted with high-quality local varieties, and local crops cannot be planted in the Great Mo Realm in the short term.

Therefore, our entire project is based on hybridization of crops from the Great Mo Realm. "

Then Xiang Hua paused, seemed to think of something, and said with some sigh:

"Rice is a very strange thing. It is a hermaphrodite crop. If no intervention is done, they will self-pollinate and there is no way to cross with other rice species.

In the local area, due to underdeveloped technical means in the early years, the teacher first looked for natural male sterile strains, that is, female rice, for hybridization.

The teacher spent a full five years and only got a total of 6 natural daughter rice plants.

After that, he searched for suitable male strains for these sterile strains. This search took another six years.

That’s a whole eleven years in one go. How many eleven years are there in a life? "

When Lin Li heard this, his face couldn't help but look a little heavy:

"Researcher Xiang, is this the same method you use in the Great Mo Realm?"

Xiang Hua shook his head when he heard this and said with a smile:

“It’s much simpler now than before. The local technology of manual stamen removal is very advanced and can handle most situations.

And with the help of spiritual thoughts in the Great Mo Realm, sterile strains can be easily found.

This is the case for Houji-1, for example.

After the teacher used his spiritual thoughts to find suitable orphan rice seeds, we carried out pollination and crossbreeding of different strains, and then used spiritual butterflies to help grow them. Finally, we have these first-generation seeds you see.

We will next focus on these first-generation seeds to further optimize more suitable rice seeds. "

Lin Li nodded approvingly and was about to say something when he suddenly came to his senses:

"Wait a minute, you mean... Mr. Yuan's spiritual thoughts?"

Xiang Hua smiled at him and nodded:

"That's right, Teacher has broken through the fourth level of Qi training, and his body and bones have improved a lot.

Oh, by the way, he said that before.

If you don't see him in person, it means that he is resting or taking Xiao Mo to play. Let me remember to tell you that everything is fine. "
