Thirteen years of Yuan Heng.

This year, Li Chong has reached the age of sixty-seven.

Although he is obviously a little older, it doesn't affect anything at all.

For example, this kind of land.

In the experimental field, both wheat and onions grew extremely well.

Experiments have proved that potassium sulfate and potassium chloride do have the effect of increasing crop yields, and even seem to make plants have a certain ability to resist lodging.

Because the wheat that has not been applied potassium sulfate and potassium chloride has more or less fallen down.

But, having used it, the wheat seemed to show no signs of falling at all.

Moreover......

The wheat seedlings grew incomparably stronger.

It looks very lush and green.

There are also more tillered leaves.

In April and May of this year, the first harvest is onions, which can only be said to be really like using technology and hard work, all of which grow almost the same size.

If you look at other onions that have not used potash, they will grow one big and one small.

Isn't this typical of technology and ruthlessness?

Then, after this harvest was finished, it was naturally made for five Japanese girls to eat.

The essential......

One by one, they seemed to be eating deliciously.

After the onion harvest is finished, it is about the same time that the wheat can be harvested.

This wheat is the same as onions, nothing else has used potassium sulfate or potassium chloride, and the wheat grows really hard to describe.

And the used ones can even be twice as large as the unused ones.

That's the gap!

In the last weighing statistics, wheat without fertilizer can only produce about one stone or two buckets at most, and those who use farmhouse fertilizer can produce almost two stones, and those who use Li Zhong's potassium sulfate and potassium chloride fertilizers, and also apply farmhouse fertilizer, this yield is surprisingly at least four stones.

All I can say is......

It's also terrifying.

You know, the southern paddy field is only an average of three stones.

Of course!

Li Zhong feels that there is still room for this output to continue to increase.

Because......

He hasn't used the nitrogen fertilizer or phosphate fertilizer yet.

If he can make use of these two, it is not Li Chong's bragging, he feels that there is nothing wrong with producing six or seven stones.

If you pick this kind of seed again, improve it.

That acre of land is 800 catties of wheat or something, it shouldn't be a big problem.

Next......

Naturally, all the wheat harvested went into the stomachs of the five Japanese girls.

All I can say is......

I think it's working pretty well.

Not only did the body of the five Japanese girls not feel any discomfort, but in the past two months, their weight has grown by four or five pounds.

After Xincheng learned of Li Chong's intentions, he also called Li Chong not a person.

Such a lack of virtue can be done.

How can this be experimented on with living people?

What if you really want to eat a good meal?

Li Chong can only say that someone must sacrifice for this, and a few of them should be regarded as dedicating themselves to the food and clothing of the people of the Tang Dynasty.

Of course!

There is also one thing to say.

Although this experiment was very successful, how to control the synthetic cost of chemical fertilizer is also a very important issue.

At least......

At present, the cost of synthesizing chemical fertilizers using laboratory methods is definitely not affordable for ordinary people.

It's best to be able to find some ore.

Can be mined in large quantities.

Li Zhong handed over this matter to relevant professionals to deal with.

That......

Recently, there have been rumors in Luoyang City that Li Zhong is alchemy.

This kind of thing is not very unusual.

After all......

Many dignitaries and nobles in Datang have their own alchemy.

Everyone was just curious, if Li Chong, the former dean of the Academy of Sciences, came to alchemy, would he do something surprising to them?

For example......

Maybe he can refine an elixir that can live forever.

For others, it's definitely not a big deal.

But if it's Li Chong......

He's the man who can do miracles, after all.

This year.

The government used steam tractors to harvest wheat and proceeded very smoothly.

In less than ten days, the wheat around Luoyang was basically cut.

Such a speedy way also subverted the perception of the people of Datang on farming again.

If this is the case every year, then basically the people of Datang can say goodbye to farming.

Of course!

This is just an exaggeration, there is nothing wrong with growing wheat, but planting other ones, this is open to discussion.

But......

Over the years, the Academy of Sciences has also been trying to grow other food crops.

Take soybeans, for example.

How to make soybeans can be planted and harvested on a large scale is also very important.

And......

Speaking of which, soybeans also have the effect of nitrogen fixation to maintain fertility, and it is best to rotate with other crops.

this year.

The big cannibal reached as far as Bukhara, this Bukhara, you say it is the territory of the Tang Dynasty, it seems to be counted.

Merely......

At this time, this place was also a grazing place for the Western Turkic Tiele people.

Then, it can only be said that when Pei Xingjian is dealing with ethnic relations, he should be able to handle it.

This also led to the fact that the Tang Dynasty did not need to send troops, and this big cannibal had already been repelled by the Alishi Department of the Tuqi Shi.

If Datang wants to participate in this war, then he has to walk at least 4,000 miles on the road.

This is probably why Datang is not interested in going west to attack Dashi.

It's still four thousand miles since people walked into your face.

If it hits the other party's hometown, wouldn't it be even farther?

With the presence of the people of the Alishi Department, the west of the Tang Dynasty is not afraid that the big cannibals will attack it.

Merely......

The Alishi division of this turk must not be guarded against.

This year, on Li Tai's side, when the ship was furthest, it also reached Persia.

All I can say is......

It doesn't seem to be much necessary to go any further.

Even......

As long as they can go to Tianzhu, they are already good.

Anyway......

Tianzhu can be used as a distribution center, where large and small businessmen gather.

But......

This is the same as the governor of the big cannibal or something, and I still want to meet him.

After all......

This will open up trade routes for them.

The governor of the Persian side of the Great Cannibal immediately sent an envoy from Li Tai to their capital, Damascus, to meet their caliph, Muawiyah I.

This Mu'awiyya I was undoubtedly a male ruler, because at this time, the territory of the Great Eclipse reached the westernmost part of Europe in the west, the northwest of Tianzhu in the east, the Turgish in the north, and the southern and northern parts of Africa were also conquered by them.

With such a large territory, it can only be said that it looks no worse than Datang.

Then, the two sides had a friendly exchange.

It is nothing more than that the country of Cochin can provide silk, and then everyone has money to earn together.

Mu'awiyya also inquired about the envoys sent by Li Tai.

For example, this Jiaozhi country, this Datang.

For all kinds of things in Datang, he is naturally fascinated, and ......

He also found that the quality of the paper brought from Datang was good.

If it weren't for Li Tai's people who didn't know how to make paper, otherwise, it is estimated that these people would have been left behind by Muawiyah.

I had to teach them how to make this kind of high-quality paper before I let them go.
