People are in the Tang Dynasty, creating a mythical dynasty

Thinking of this, his gaze at these potatoes became even brighter.

National power, that is national power.

Eyes with excitement.

The next moment Li Ming didn't hesitate anymore, he picked up the ten catties of potatoes, and quickly walked towards Shaofu.

With this artifact.

Of course he couldn't wait for this moment.

It just so happens that the greenhouse is now a little empty, and it is completely possible to start planting.

Chapter 62 A must for cross-farming, under potatoes

Shaofu.

Now with Li Ming serving as the supervisor of the Shaofu, the Shaofu is undoubtedly busier.

At this time, the Shaofu not only has the original things, but also has several more things.

For example, breeding chickens and ducks, earthworms, refining refined salt, refining snow sugar, and purchasing Imperatae at the same time.

Although Bai Mao's speed began to decrease as time went by, it was still a cumbersome job.

But Li Ming didn't care about these at all.

He just needs to explain it, if it doesn't work out, it's their business.

Just like this moment.

Li Ming rushed to the Shaofu in a hurry, and soon called the Shaofu supervisor over again.

This time several farmers are required.

After the Shaofu Supervisor agreed, he quickly brought in manpower.

Three in total.

They are all experienced farmers.

"Look carefully, are there bud eyes on this potato? If the whole potato seed is planted, many seedlings will appear in one planting hole. Not to mention wasting the seeds, it will make the seedlings too dense and affect the yield of potatoes. Therefore, potato seeds It is recommended to cut into pieces."

"When cutting the seed block, try to leave the bud eyes on the top. One or two bud eyes are enough for each seed block. As for the potatoes at the end, you can use it or not."

"After the potatoes are cut into pieces, there will be cuts, so we need to sprinkle plant ash on the cuts of the potatoes!"

After speaking, Li Ming took out a small knife and slowly cut open a potato under the blank eyes of several farmers.

One or two fists were directly cut into four or five shapes by him carefully.

"Well, Your Highness, won't the seeds go bad like this?"

Seeing Li Ming's movements, a farmer couldn't help but speak.

In their cognition, they haven't separated the seeds yet.

As he spoke, the other people also had strange expressions on their faces.

And faced with the weirdness and curiosity of a few people.

Li Ming pondered for a moment, but he still opened his mouth to explain.

"No, this is a seed from a distant continent. It has a special feature. The special feature is that each seed is in the bud eye."

"Just do it my way."

The words were simple and didn't go into details, and he didn't understand even if he couldn't ask him to go into details.

"promise!"

Although the few people were still full of curiosity, they still followed their words.

And in the action of several people.

Li Ming greeted another person and began to work in the shed.

Now there are just vegetables that have begun to mature and can be picked.

There is no doubt that a new greenhouse will be vacated.

And this greenhouse is naturally where Li Ming plans to grow potatoes.

Compared with ordinary vegetable cultivation, the cultivation of potatoes requires more trouble.

The growth of potatoes has very high requirements on the soil, which requires soft and breathable soil. Therefore, when plowing the land, it needs to be plowed slightly deeper. In the previous life, it was about 40 cm. According to the fertility of the soil, an appropriate amount of farmyard manure was applied. Then stir evenly, and then form a ridge to increase the soil thickness of the planting layer.

Tilling the land is undoubtedly very cumbersome in this era.

This is especially the case when it is relatively deep.

Fortunately, these are old farmers.

And it's still too small.

For other common people in the Tang Dynasty, farm tools are still extremely lacking, but for the Shaofu, there is naturally no shortage.

Plowing was done in no time.

Ordinary potato seed blocks, generally about 350 catties can be planted in one mu of land (667 square meters), so ten catties of potato seed blocks can be sown in an area of ​​about 25 to [-] square meters.

What Li Ming got when he signed in was a special kind of potato.

Its planting area is wider and can reach about forty square meters.

Naturally, such a small range does not require much time.

And after plowing the land.

Just apply the right amount of farmyard manure.

There are ready-made and decomposed feces used in the cultivation of earthworms, which are completely applicable.

Soon it was a matter of finishing the land.

Then you just need to wait for the potatoes to germinate before planting them.

And it doesn't take long to wait.

Put it in a greenhouse.

With sufficient temperature and direct sunlight, in less than fifteen days, seedlings began to emerge.

Look at the potato seedlings that are gradually exposed.

The few farmers couldn't help being surprised.

They didn't expect that the potatoes could actually germinate after they were cut open.

All of them were shocked and confused.

There was a new change in the eyes looking at Li Ming.

Li Ming didn't care about the changes in the eyes of these people.

After all, he has gone through this journey several times.

Compared with this, he is more concerned about the planting of potatoes, which is related to the entire Tang Dynasty.

If my father knew about it, I'm afraid he couldn't take it too seriously.

Although he didn't plan to say it now, it was inevitable to pay attention to it.

No. On the 16th day, he began to direct people to plant potatoes.

Compared with other cultivations, the cultivation of potatoes can be said to be somewhat different.

Before planting potatoes, dig out several planting pits in the plot according to a certain interval, the pits are about 20 cm deep, and then sprinkle half a pit of farmyard manure + plant ash into the pits, and then sprinkle a thin layer of soil, Slightly cover the farmyard manure in the pit, plant the potato pieces with the bud eyes facing upwards, and finally cover with about 1.5 cm of soil, and cultivate the soil after the potatoes emerge.

This is a very delicate step.

During the whole process, Li Ming held the planting manual and taught the old farmers how to plant.

He didn't breathe a sigh of relief until it was completely planted.

After the potato pieces are planted, the seedlings will emerge in about 5 days. At this time, there is no need to worry about it, because the main source of nutrition for the potato seedlings at this time is the potato pieces.

You need to wait until the potato seedlings grow to a height of more than 15 cm, and there are a lot of leaves. At this time, you need to start topdressing.

And if possible, it is best to use nitrogen fertilizer as the main direction of fertilization, and you can use fermented liquid fertilizer + chicken manure or potassium sulfate fertilizer.

Compared with the previous life, it is naturally impossible to have ready-made purchases in this era.

Then you can only do it yourself.

Fortunately, the production method of nitrogen fertilizer is not too complicated, and there are related production methods in the sign-in.

One or more of soybeans, peanuts, and melon seeds can be crushed, fried, sealed with water, and can be rotted and fermented into organic nitrogen fertilizer in about half a month.

Although peanuts and melon seeds do not exist in Datang today, soybeans do exist.

And the number is not low.

Generally, when farmers are planting wheat and corn, they will plant some soybeans in their spare time. These soybeans are generally used to satisfy hunger in times of famine.

Shaofu naturally has many.

Li Ming directly asked someone to make some.

Nitrogen fertilizer is prepared in half a month, and the potato seedlings will grow to the height of later generations at that time, and there will be no delay.

Chapter 63 Locusts begin to hatch

Compared with ordinary potatoes, this time it is considered refined planting.

In the previous life, potatoes were generally planted in October-December, but the specific planting time is related to the local climate. The Northeast and Gansu, Qinghai and other Northwest are planted from mid-to-late April to early May. Most potatoes are planted in 10-12 months. It can mature in the middle of the year, and it is slower in the northwest. It is generally not mature until autumn.

As an experimental species, the potatoes this time need to mature earlier than ordinary potatoes.

Even in the northwest, there is a high probability that it will only take about three months, and it will mature in no more than four months.

And if it is in the south, it is even enough to fully mature in about two months.

And its output is enough to make one's scalp tingle. Under normal planting, it can reach a maximum yield of 5136 kg per mu, which is a real top high-yield crop.

For this small piece of land, he was extremely caring the moment he planted it.

After all, this is the key to whether Datang's national strength can advance rapidly.

Many things cannot be fully unfolded now.

One of the most critical points is food.

For example, there is not enough food for raising pigs. The so-called popularization of raising pigs is a joke.

Even if the locusts can support it, the locusts will eventually pass.

In particular, it must be popularized throughout the country. Locusts alone cannot make up for it. It is necessary to ensure that food production can keep up.

The most important reason why the breeding industry was so developed in the previous life is the horrible grain production in China every year.

Otherwise, it would be impossible for the aquaculture industry to go up.

For Datang, this is also extremely critical.

Originally, Li Ming was still considering how to increase Datang's output.

For a person of later generations, and for him who has signed up for various technologies, it is not too much of a problem to increase the grain production on the basis of Datang's original.

For example, more effective planting methods and more scientific planting types.

As well as disease and pest control, various fertilizers.

These are enough to increase food production.

But these are not the key issues that can really solve the grain production.

In later generations, pesticides and fertilizers are of great importance, but higher-yield crops are the key. Without high-yield crops, Datang's food production will be limited after all, and it will not be able to meet his needs at all.

The advent of potatoes today certainly satisfies this last condition.

With only such a few potatoes, Li Ming naturally didn't want any surprises. After all, he really didn't know that he would be able to sign in next time.

Especially these potatoes, not ordinary potatoes.
