Busy going on quickly, the construction of the greenhouse was quickly completed, followed by sowing.

In Datang.

Due to the opening of the Silk Road in the Han Dynasty, there are not a few vegetables that can be eaten today.

Leeks, cabbage, spinach, shepherd's purse, cucumber, lettuce, peas, winter melon, wild rice, purple horn leaves, water spinach, daylily, radish, cress, amaranth, turnip, ginger, yam, lily, mustard.

These exist in every era.

And Li Ming did not plant it on a large scale.

Instead, they planted some of more than ten kinds of vegetables.

As for Li Ming's decision, the young government officials couldn't help but look weird.

Plant in winter.

This is something they have never heard of.

Even a little confused.

After all, spring planting and autumn harvest have been practiced since ancient times, and there has never been a saying of winter planting and summer harvesting.

"Your Highness, this, this?"

Some officials from the Shaofu couldn't help but ask.

"Just listen to me."

"By the way, these things must be done according to my instructions."

"Remember to heat the furnace wall when the temperature is too low, and add more hay."

Li Ming waved his hand and did not explain, but let these people continue according to his ideas.

Although the staff of the Young Mansion were still full of doubts and curiosity, they still followed Li Ming's orders and deployed one by one.

Ten greenhouses.

It seems like a lot.

But not much.

The sowing was completed in just two days.

As for sowing seeds, Li Ming did not participate.

On the one hand, he has no knowledge about signing in, and on the other hand, he is actually not very familiar with agriculture.

The only thing he intervened in was retting.

In this era when fertilization has just appeared, it is not perfect.

According to ancient records, "stepping manure", that is, the production and utilization of manure, appeared in the sixth century AD in our country; it was not until 1591 that the "steaming manure method", that is, the method of accumulating and utilizing compost, appeared; in 1633, "brewing manure" began

"Shit method".

Now it is just the earliest stage of "fat stepping"

The retting at this time is not actually a complete retting.

As a time traveler, Li Ming still has some memories of retting.

In addition, during the sign-in, there are also some retting techniques, so it can be easily done by directing everyone to perfect the retting.

Simple retting technology refers to mixing and accumulating organic waste such as human excrement, inedible rotten leaves, animal excrement, weeds, straw, waste and garbage, sealing it with mud, and then using the fermentation of microorganisms under natural conditions to make the pile material

The organic matter in the soil matures and reaches an acceptable level of stability for the soil.

As for the steps, they are even simpler.

First, dig a pit on the ground. The size of the pit depends on the amount of piled materials. Generally, a square or circular pit with a depth of 3 feet and a length and width of 6 feet is used. The excavated soil piles are surrounded by earth walls.

At the same time, dig a cross-shaped ventilation ditch between the bottom of the pit and the four pit walls, leading all the way along the pit walls to the opening on the ground.

When composting, first use straw or branches to stand on the ditch, stand up wooden sticks or straw at the intersection of the cross ditch, and then fill the prepared pile into the pit. The ingredient method is to chop the straw etc. to a length of about 1 inch, and soak it in water

Wet, mix weeds, leaves, domestic garbage, etc., then add about half the amount of cow and horse manure to the above mixture, and sprinkle an appropriate amount of water and manure.

Add water once for each layer of the pile. The total water added is about 45% to 55%, so as not to flow out, which is beneficial to the decomposition and decomposition of organic matter and the activity of microorganisms. After the pile is full, it is not suitable to be solid, and only another layer of water is applied on the top. 1

~2 inches of thick mud or thin mud. After 2 to 3 days, pull out the wooden stick or straw inserted in the middle to form a ventilation channel.

The decomposition time is generally about 20 days. The color of the decomposed material is black or brown, has no smell, and is soft in texture. It can be kneaded into a ball and crumbled when rubbed, and can be used as fertilizer.

If done now, it can basically be used to fertilize vegetables twenty days later.

Compared with the "step fertilization" that has just become popular nowadays, although this is a simple fertilization, the effect is also extremely outstanding.

It is enough to play a big role in planting in this era.

Of course, in modern times, retting can also produce biogas.

In this era, Li Ming gave up after thinking about it.

Biogas will explode if you don't handle it properly.

Its power is not much worse than that of nitroglycerin.

Once a large-scale explosion occurs, the joke will be big.

In addition, the demand for biogas is not that big nowadays.

Of course he won't think about it.

Now he just needs to calm down and improve the national power of the Tang Dynasty.

It’s better to avoid things that are too dangerous.

The figure is busy.

Greenhouse planting is also in progress.

It is now December, and although the weather in Chang'an has not reached subzero, and there is no snow this year, the temperature is only about three or four degrees.

Planting in greenhouses with such temperatures undoubtedly requires heating.

In this era, there is no heating or daylight.

The only way to heat is firewood.

Several fireplaces were burning, releasing heat to the entire ground.

Although this is bound to cause the temperature of the fireplace to be too high and the edge temperature to be low.

But this is the ultimate that can be achieved in this era.

At least it can ensure that the temperature of the ground in the middle area is within a suitable range.

As for the rest, there is nothing we can do.

As for the people in the Young Mansion, everyone looked at it with curiosity.

Waiting for the results to happen.

Planting in winter was almost impossible in their past memories.

But this is Li Ming, His Royal Highness King Wei, who has made many impossible possibilities possible.

In this case.

They couldn't help but look forward to it.

Even the Shaofu Superintendent came to see it several times.

Of course, he was not heartbroken over the sizzling firewood.

With a steady stream of income from refined salt, it can be said that he is basically not panicking.

Not to mention burning so much firewood, even if it were ten times more, he would not panic at this moment.

No matter how expensive firewood is, how can it be as expensive as refined salt?

What he is curious about is whether this geography can really grow.

And the results did not disappoint them.

In less than five days, the seeds of the vegetables in the field have sprouted.

"It's sprouting!"

"It's sprouting!"

"It's really sprouting!"

The sudden exclamation echoed through the greenhouse, instantly attracting the attention of countless people.

Soon, figures one after another quickly gathered around.

And when they saw that touch of green in the ground, everyone's eyes couldn't help but straighten.

Although everyone had some expectations in their hearts, when the winter seeds sprouted, their faces couldn't help but flush.

So when Li Ming arrived, these people looked at Li Ming as if they were looking at gods.

That's right, it's a god.

Today, Li Ming is no different from a god in their eyes.

Chickens and ducks hatch.

Earthworm breeding.

Plant in winter.
