Squatting down and hesitating for a moment, Zhang Yue finally buried the jade fruit in his hand in the soil under Mai Miao.

Anyway, he's rich now.

The books that Taixue gave him were enough to squander them like this for a long time.

As soon as the jade fruit was buried in the soil, as in the previous three times, the wheat seedlings immediately began to grow at a high speed.

In an instant, it was a few inches taller.

But Zhang Yue's expression was even more exaggerated than the miracle of the reaction between the jade fruit and the crops when he saw it for the first time, because a picture appeared in front of his eyes that made him unbelievable.

Just like the scene of a science fiction movie, three images of three-dimensional wheat He appeared in front of his eyes.

The three wheat plants are all similar in shape, but slightly different in details.

Two more ears of wheat per plant, up to five ears.

Wheat is known to be tillered.

Even in this pre-AD world, if the wheat seedlings at the tillering stage were properly managed, with the right amount of moisture, temperature and fertilizer.

Then, by the time the heading is taken, a wheat plant may produce three, or even more than five ears.

In later generations, due to the development of scientific planting technology and the continuous progress of wheat seed cultivation.

Some high-yielding wheat varieties can even produce eight ears.

However, these are the exceptions.

In fact, even in later generations, too much tillers of wheat may cause its development to be stunted or lodging.

Today, there are no chemical fertilizers, let alone advanced wheat cultivation management techniques.

So too much tillers of wheat is not a good thing, but a disaster!

The other plant has only two normal spikes, but it is obvious that its root system is much more developed than that of the five spikes, not only with longer roots, but also with significantly thicker roots.

This shows that it is more resistant to drought and waterlogging and even has a stronger ability to absorb nutrients.

The stalks of the last wheat plant were noticeably thicker than the other two, and the leaves were thicker.

This means that it is more resistant to lodging and water storage!

To put it simply, there are three choices in front of Zhang Yue's eyes.

A path to high yields, but with great risks.

A path that points to greater viability and resistance to weeds.

The last one is...... The way of foodies.

The leaves are larger and thicker, the photosynthesis capacity is stronger, the wheat kernels may also have more nutrients, and the wheat kernels themselves will be fuller.

However, the increase in the size of individual wheat will inevitably lead to a decrease in the density per unit area.

As a result, production is likely to be relatively low.

Three paths, three choices.

Zhang Yue thought about it and finally chose the second one.

The more developed the root system, the stronger the viability and the stronger the absorption capacity of fertilizers.

In this pre-century agrarian society, such crops had a future!

After all, in this era, there is no fertilizer industry, let alone advanced machinery to plough the land.

Agriculture is still in the era of extensive farming, and farmers generally rely on the weather for food.

Choosing the first path is undoubtedly a dead end!

You may not be able to grow ordinary wheat well, and you still want to plant five ears?

Didn't wake up, did you?

As for the third way......

Delicious, can it be better than having a full stomach?

This is not the afterlife!

After making this choice, the wheat seedlings in front of Zhang Yue's eyes immediately changed drastically.

In the stream, there are three consecutive streams.

The leaves and stalks of the wheat began to shake.

A few seconds later, it seemed that Yuguo's energy was exhausted, and Mai Miao's upheaval was over.

In the end, what appeared in front of Zhang Yue's eyes were more than a dozen mature wheat plants about 60 centimeters tall with golden ears of wheat.

He reached out and plucked one of the ears of wheat, took it in his hand and weighed it, and it looked like seven or eight grams.

Nowadays, the Han family's acre system is a large number of acres.

One acre of land is one step wide and two hundred and forty steps long, while the Han family stipulates that one step is six feet, and one foot is about 23 centimeters in later generations.

One acre of land in the Han Dynasty is about 330 square meters in later generations, which is basically more than half an acre in later generations.

In this case, the yield per mu is likely to reach an astonishing eight stones, about two hundred and fifty kilograms!

This is undoubtedly terrifying data!

Of course, this is the yield of space.

If it is transplanted to the outside world, at least make a fold.

After all, there were no chemical fertilizers in this era, and the farming technology was even stuck in the era of extensive farming, and the farmers purely depended on the sky for food.

Even ox farming has not yet been popularized, and it will take at least six years for the two-ox pole technique in history textbooks to be promoted.

Cultivating or something, completely staying in the imagination.

Even so, such a yield is exaggerated enough.

But Zhang Yue realized another problem.

"Perhaps, space is used to cultivate crops, but it is only its most basic, inconspicuous, and even the most inefficient ......function," Zhang Yue thought to himself as he touched the ears of wheat in his hand.

In this era, there is no industrial fertilizer, and there is no mechanized production.

Not even a zigzag plow.

Many remote areas are even stuck in primitive times hundreds of years ago.

The people slash and burn, and even the farm tools are many stone tools and wooden tools.

Productivity is extremely low.

Even if he relied on space to cultivate those high-yield grain varieties in later generations.

Who can grow it again?

I am afraid that it is hybrid rice, and in the hands of farmers in this era, it is likely that the yield is only three or five hundred catties.

I want to be like the future generations, and I can yield a ton per mu at every turn.

That requires a complete fertilizer industry system.

Ammonia, nitrogen, urea are required.

There is also a need for a complete chemical industry system, which requires large quantities of pesticides and herbicides.

But these things, obviously, could not have appeared in this day and age.

Zhang Yue couldn't have conjured them out of thin air.

So, it's the space that breeds high-yielding seeds.

The inefficient production technology of this era cannot be monetized.

However, the new function of the space that has just appeared has opened a new window for Zhang Yue.

Since there has been a function that can choose the direction of crop development or strengthening.

So is it possible to strengthen certain characteristics of certain plants at a fixed point in space?

For example, there are no rubber trees in China.

It is impossible for the current navigation technology to cross the ocean and let the current China get rubber seeds.

However, China has Eucommia.

Zhang Yue remembered that it seemed that in later generations, there was a technology to replace rubber with eucommia gum.

It's just that the yield and quality of eucommia gum are significantly lower than that of rubber, so the cost performance is very low.

However, now there is space at hand to selectively enhance certain functions of the plant.

Isn't it possible to breed a kind of eucommia that is comparable to a rubber tree in this space?

Thinking about it this way, Zhang Yue felt that it was very feasible!

At the very least, you should try!

Even if it fails, it doesn't matter, it can provide valuable experience and technology for the enhancement and cultivation of other plants in the future, and it can also allow you to further understand and explore the space.

It's just that now it's obvious that you can't try it anymore.

Because, I've been in this space for too long.

In case, Rou Niang or sister-in-law came to look for her, but found that she was not in the room, how embarrassing would it be?

Zhang Yue had no choice but to put aside his thoughts for the time being, close his eyes, and leave the space.
