The three-garden system is also known as the "three-field system" and "three-zone rotation system". Pen, fun, pavilion www. biquge。 infoA cereal-growing system that prevailed in medieval European countries. At that time, due to the progress of production technology, especially the popularization of wheeled heavy ploughs, large-scale land development activities increased a large amount of arable land, and after the 8th century, the three-garden system prevailed in Central and Western Europe with flat terrain, humid and cool climate, and heavy soil. It divides cultivated land into three cultivated areas: fallow land, spring sowing land, and autumn (winter) sowing land, which are roughly equal in area. Crops are also rotated in the districts, with spring crops or barley or oats or legumes, and autumn (winter) crops or wheat or rye. Cultivated land and crops are rotated year by year, with a three-year cycle.

(Of course, the above is definitely not the author's making up the number of words) Tang Meng quietly recalled the knowledge learned in biology class, but he still had a clue, after all, the teacher didn't elaborate. But then Arni spoke.

"Actually, you still don't understand why I'm showing you this, so I'll give you some hints. What we have been seeing is indeed the historical process of the continent of Goblez, and it is in it that I want to ask. Yani said slowly, his eyes looking at Tang Meng.

At this time, all the worlds began to change again, as if there was a magical force, which made the whole world shatter into pieces, and then Tang Meng and Mar were in nothingness, and then the whole world was reorganized again, like glued pieces, and there was a piece of perfect world.

So Tang Meng and Mar found that they were now in the middle of the countless wheat, and in front of them was still the throne, and Arni was sitting there, smiling and looking at them.

Mar stomped lightly on the ground, and found that it was solid earth, so she breathed a sigh of relief, she had just floated in the sky, if it weren't for those historical fragments to distract her, she was afraid that she would have fainted.

"I think you've given enough hints, maybe what you want to test us should be about grain planting?" Tang Meng asked tentatively.

Arni nodded slowly, then stood up, facing the endless rice fields, and snapped his fingers slightly. So the wheat swaying in the wind began to quickly turn into a seed.

Can you imagine such a vast wheat field, and now all the wheat has become its original appearance, as if it had been harvested en masse. Then time seems to speed up, and each wheat sprouts, emerges, tillers, overwinters, regreens, joints, booting, heading, flowering, filling, and ripening. These processes repeat themselves quickly, like endless cycles over and over again.

"The growth of food is so repetitive, silently contributing everything to humanity and feeding the world. But God said that it was their work, and the people thanked the gods, but they were not grateful for the insignificant grains. ”

In short, Tang Meng and Mar watched this process incredibly, like watching a fast replay of a movie, and after listening to Yani's words, their mood at the moment was very complicated.

"So, what do you want to ask?" Tang Meng said as he looked at Yani seriously.

"I just wonder if there's a way to increase food production, that's all. If you can name one, I'll pass you. Arni said lightly.

This question made Tang Meng stunned, he never thought that it would be such a question, after all, it must be a high-end question about the origin of the relationship between God and planting, or the influence of religion on planting, right?

Seeing Tang Meng's puzzled eyes, Yani thought that he was in trouble, and Yani was also a little unbearable. He thought: Well, yes, the method of increasing grain production for thousands of years has not been tried by anyone, but there are too few results. After all, those who succeed will be the pioneers of mankind. But that's the purpose of building this palace in the first place, and it's the reason why I protect it here. For humanity to go further, that's all.

"Young man from the Eastern Continent, I'm still quite optimistic about you, after all, you are from the Eastern Continent, maybe there is really a way to increase food production. Twenty years ago, they had been here, but they still couldn't answer, that the nun had prepared a method of illuminating the grains with holy light, but it didn't seem very practical. Yani said that he first encouraged Tang Meng, and then recalled some things from the past.

"Lady Arni, are you talking about my parents?" asked Marr when she heard this.

"Parents?" Arni muttered to herself, then looked Marr up and down for a moment, and then said, "Oh, so you are their daughter? ”

"It turns out that the way to enter this palace is difficult?" Tang Meng asked on the side, he wanted to know more about this palace.

"Actually, it's not, I ...... it at the beginning" Suddenly Arni seemed to realize something and closed his mouth in time.

At this time, the surrounding wheat also stopped growing again, and there were golden waves of wheat here.

"Could it be that there is any secret involved in this? Maybe it is not necessarily the reason for the construction of this palace?" Tang Meng boldly guessed.

"This ...... Okay, stop guessing. Arni said with some weakness, "You can think about it slowly, I can give you a month, although it is difficult, but I hope you can come up with it, so that you can also contribute to humanity." ”

"For a month, Master Tang Meng and I have brought three days' worth of dry food?" exclaimed Mar.

"Don't worry, there is so much food here, enough for you to eat. That's how your parents came over, and then they seem to be still emotional? I really don't understand. Arni said slowly, shrugging her shoulders.

Mal's face turned red as an apple, and she was speechless for a moment.

It turns out that parents love each other like this? Mar thought, and secretly glanced at Tang Meng, who was thinking next to him.

Immediately, Arni stretched out his hand and drew an inexplicable trajectory in the air, and a portal appeared, and he made a gesture to leave.

"Wait!" Tang Meng called out to him.

"What's the matter, young man from the Eastern Continent, don't you look like someone who wants to give up so early?" Arni asked, thinking Tang Meng was going to give up.

"No, I'm not giving up, but I've already thought of the answer, one can increase grain production by 20 percent. Tang Meng said lightly.

Arni jumped up all of a sudden, this young man couldn't speak with a brain, how could this be? If this is the case, then how many people can the world feed?

"If you lie to me, I will not hesitate to send you out, and I will not let you enter this palace for the rest of your life. Arni said in an unkind tone.

Tang Meng nodded, and then thought to himself, it was really good to know a scientist from Huaxia Kingdom, Yuan!

It turned out that Tang Meng's contemplation just now was actually recalling the content of Huaxia Guo's biology class...... (To be continued.) )
