After squatting down and hesitating for a moment, Zhang Yue finally buried the jade fruit in his hand in the soil under the wheat seedlings.

Anyway, he is very wealthy now.

The books given by the Taixue were enough to make him squander like this for a long time.

The jade fruit was just buried in the soil, and the wheat seedlings immediately began to grow at a high speed just like the previous three times.

In an instant, it was lifted several inches higher.

But Zhang Yue's expression was even more exaggerated than the miracle that first saw the reaction between jade fruit and crops, because there was a picture that he couldn't believe in front of him.

Just like the scene in a science fiction movie, three three-dimensional images of Mai He appeared in front of him.

The three wheat plants are all the same in shape, but they are slightly different in details.

There are two more ears of wheat in each plant, reaching five ears.

As we all know, wheat is tiller.

Even in this world of BC, if the wheat seedlings during the tillering stage are properly managed, the moisture, temperature and fertilizer are appropriate.

Then, by the time of earing, a wheat plant may produce three or even more ears.

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

Some high-yield wheat species can even produce eight ears.

However, these are just special cases.

In fact, even in later generations, too much wheat tillering may cause it to develop poorly or fall.

As for today, there are no fertilizers, and no advanced wheat cultivation and management technologies.

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

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

This shows that its drought resistance, flood resistance and even nutrient absorption capacity are stronger.

The stems of the last wheat plant are obviously thicker than the other two plants, and the wheat leaves are thicker.

This means that its resistance to lodging and moisture storage ability is stronger!

Simply put, there are three choices in front of Zhang Yue.

A path to high productivity, but with great risks.

A path to stronger survivability and stronger weed resistance.

The last one is...the path of foodies.

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

However, the increase in wheat will definitely lead to a decrease in density per unit area.

Therefore, the output may decline relatively.

Three paths, three choices.

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

The more developed the root system, the stronger the survival ability, and the more fertilizer absorption capacity.

Only in this agricultural society before the B.C., such crops have a future!

After all, in this era, there is no fertilizer industry, and no advanced machinery to cultivate the land.

Agriculture is still in the era of rough farming, and farmers generally rely on the weather for their own income.

Choosing the first path is undoubtedly a dead end!

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

Haven't woken up?

As for the third road...

Is it better to have a full stomach?

This is not later generations!

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

The stream flowed three times in a row.

The leaves and stems of wheat began to shake.

After a few seconds, it seemed that the jade fruit's energy was exhausted, and the drastic changes in the wheat seedlings ended.

Finally, what appeared in front of Zhang Yue were more than ten wheat plants that were about 60 centimeters tall with golden ears and were already ripe.

He reached out to pick the ears of one of the plants, took them in his hand and weighed them, and it looked about seven or eight grams.

Today, the Han Dynasty's land acre system is large.

One acre of land is one step wide and two hundred and forty steps long, but the Han Dynasty stipulated that one step six feet, one foot is about 23 cm in later generations.

Therefore, one acre of land in the Han Dynasty was about 330 square meters in later generations, which was basically more than half acre in later generations.

In this way, the yield per mu is likely to reach an astonishing eight stones, about 250 kilograms!

This is undoubtedly terrifying data!

Of course, this is the output of space.

If transplanted to the outside world, at least it will be folded in half.

After all, there is no fertilizer in this era, and the farming technology is even stuck in the era of rough farming. Farmers rely solely on the weather for their own gain.

Even ox plowing has not been popularized, and the two-ox quarrel technology in history textbooks will take at least six years to start promoting.

Deeply working hard, or something, is completely in imagination.

Even so, such output is exaggerated enough.

But Zhang Yue realized another problem.

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

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

There is not even a curved plow.

Many remote areas even remained in the primitive era hundreds of years ago.

People slash and fire, and even many farm tools are stone tools and wooden tools.

Extremely low productivity.

Even if he relied on space, he cultivated the high-yield grain seeds from later generations.

Who can plant it again?

I'm afraid it's hybrid rice. In the hands of farmers in this era, the yield is likely to be only three to five hundred kilograms.

I want to produce one ton per mu like in later generations.

That requires a complete fertilizer industrial system.

Ammonia fertilizer, nitrogen fertilizer, and urea are needed.

A complete chemical agent industrial system is also needed, requiring a large number of pesticides and herbicides.

But these things are obviously impossible to appear in this era.

It is impossible for Zhang Yue to turn them out of thin air.

Therefore, it is the space to cultivate high-yield seeds.

Inefficient production technologies in this era cannot be realized.

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

Since, the function of choosing crop development or strengthening direction has already appeared.

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

For example, China does not have rubber trees.

Today's navigation technology cannot cross the ocean and allow China to obtain rubber seeds.

However, there is Eucommia ulmoides in China.

Zhang Yue remembers that it seemed that in later generations, there was a technique of using Eucommia ulmoide instead of rubber.

However, the yield and quality of Eucommia ulmoides are significantly lower than that of rubber, so the cost-effectiveness is very low.

However, now there is room in hand, which can selectively enhance certain functions of the plant.

So can we cultivate a kind of Eucommia ulmoide that is comparable to the rubber tree in this space?

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

At least, you should try it!

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

But now, it is obvious that I can't try again.

Because I have been in this space for too long.

What awkward thing if Rou Niang or her sister-in-law comes to find her but finds that she is not in the room?
