People are in the Tang Dynasty, creating a mythical dynasty

And it is different from the salt extraction technology.

Even if the greenhouse technology leaks, there is no way to place it. They don’t have plastic film, and without plastic film, there is no way to ensure enough light masks, and there is still enough warmth.

It can be said that this thing can continue to be used until the moment he really wants to popularize it.

Or wait for him to make plastic or glass before there is a possibility of imitation.

Chapter 36 Really Sprout

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

in the Tang Dynasty.

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

Leek, cabbage, spinach, shepherd's purse, cucumber, lettuce, pea, winter melon, water bamboo, purple horn leaf, water spinach, day lily, radish, cress, amaranth, turnip, ginger, yam, lily, mustard greens.

These have existed in all ages.

And Li Ming did not plant on a large scale.

Instead, they planted some of a dozen kinds of vegetables.

As for Li Ming's decision, those Shaofu staff couldn't help showing strange looks.

Plant in winter.

This is something they have never heard of.

Even a little confused.

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

"Your Highness, this, this?"

Some people from the Shaofu couldn't help asking.

"Just listen to me."

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

"The furnace wall remembers to heat when the temperature is too low, and put more hay."

Li Ming waved his hand, without explaining, but let these people proceed according to his ideas.

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

Ten greenhouses.

looks like a lot.

But not many.

However, the sowing was completed in two days.

As for sowing, Li Ming did not participate.

On the one hand, he did not sign up for relevant knowledge, and on the other hand, he was not very familiar with agriculture.

The only thing he interfered with was fattening.

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

According to ancient books, "stepping on manure", that is, the production and utilization of manure, appeared in the sixth century AD in our country; until 1591, there appeared "steaming manure", that is, the method of accumulating and utilizing compost; in 1633, "brewing manure" began. feces method".

Now it's just the earliest "stepping fat"

The retting at this time is actually not 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 composting techniques, and it is naturally easy to direct everyone to perfect composting.

The simple retting technology refers to the mixing and accumulation of human excrement, inedible rotten leaves, animal manure, weeds, straw, waste garbage and other organic wastes, paste and mud seal, and then use the fermentation of microorganisms under natural conditions to make the piles The organic matter in the soil matures to an acceptable degree of soil stability.

As for the steps, it is even simpler.

First, dig a hole on the flat ground. The size of the hole 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 mounds are surrounded by soil walls, and at the same time, a cross-shaped ventilation ditch is dug between the bottom of the pit and the four walls of the pit, leading to the opening on the ground along the pit wall.

When composting, first use straw or branches to frame the ditch, erect wooden sticks or straw at the intersection of the cross ditch, and then fill the prepared pile into the pit.The batching method is to chop the straw to a length of about 1 inch, soak it with water, mix weeds, leaves, domestic garbage, etc., then add about half the amount of cow and horse manure of the above mixture, and sprinkle a layer of water manure and urine in an appropriate amount.

For each layer, add water once, and add about 45% to 55% of water in total, so as not to flow out, so as to facilitate the decomposition of organic matter and the activities of microorganisms.After the pile is full, it is not suitable to be steadfast. Just paste a layer of 1-2 inches thick slime or thin mud on the top. After 2-3 days, pull out the wooden sticks or straws inserted in the middle to form air passages.

The decomposing time is generally about 20 days. The color of the compost after decomposing is black or brown, has no odor, and is soft in texture.

Now, it can basically be used for fertilization of vegetables after 20 days.

Compared with the "stepping fat" that has just emerged today, although this is a simple retting, the effect is also extremely outstanding.

Enough to play a big role in this era of planting.

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

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

Biogas is something that will explode if it is not handled properly.

Its power is not much worse than nitroglycerin.

Once there is a massive explosion, the joke is off.

In addition, the demand for biogas is not so great nowadays.

Of course he wouldn't think about it.

All he needs to do now is to improve the national strength of Datang with peace of mind.

Things that are too dangerous should be avoided.

The figure is busy.

Greenhouse planting is also in progress.

It is now December, and although the weather in Chang'an has not reached below zero, and this year's weather has not snowed abnormally, the temperature is only about three or four degrees.

Planting in such a temperature greenhouse undoubtedly requires heating.

In this day and age, there is no heating, no sun lights.

The only way to heat it is firewood.

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

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

But this is also the extreme that can be achieved in this era.

At least it can ensure that the temperature of the ground in the middle is in an appropriate range.

As for the others, there is no other way.

As for the people in Shaofu, everyone looked at it curiously.

Waiting for the result to happen.

Planting in winter, such a thing is almost impossible in their past memories.

But this is Li Ming, His Royal Highness King Wei, who has turned many impossibilities into possibilities.

In this case.

They couldn't help but look forward to it.

Even the Shaofu supervisor came to see it several times.

Of course, he wasn't heartbroken over the sizzling firewood.

With a steady stream of income provided by refined salt, it can be said that he basically does not panic.

Not to mention burning so much firewood, even if it was ten times more, he didn't panic at this moment.

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

What he was curious about was whether this geography could really grow.

And the result did not disappoint them.

In less than five days, the vegetables in the ground germinated with seeds.

"Sprouted!"

"Sprouted!"

"It really sprouted!"

A sudden exclamation resounded through the shed, instantly attracting the attention of countless people.

Soon one after another figure quickly surrounded him.

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

Although everyone already had some expectations in their hearts, when the real winter seeds germinated, their faces couldn't help flushing.

So much so that when Li Ming came, these people looked at Li Ming's eyes as if they were looking at gods.

That's right, it's God.

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

Chickens and ducks hatch.

Dragon breeding.

Plant in winter.

All kinds of incredible things seem to be so simple and so easy in the hands of this person.

Chapter 37 What to do with salt and no sugar

Seeds germinate in winter.

Such an unbelievable event instantly caused a lot of commotion in the entire Shaofu, and it was not until a few days later that the commotion gradually calmed down.

But the respect for Li Ming has undoubtedly reached a new level.

As I said before, compared to everyone in the Shaofu, Li Ming already existed like a god-man.

From the very beginning, I didn't care, or felt anxious.

By the time they saw Li Ming one by one, they already had respect from the bottom of their hearts.

It can be said that the attitude of the especially young prefect has completely changed.

Li Ming was naturally aware of this, but he didn't pay too much attention to it.

The days remain.

Raise chickens and ducks, and earthworms.

Greenhouse planting.

Occasionally look at his dozen or so little piglets.

As for raising pigs, he has no plans to further expand in the short term.

There is no way, the grain nowadays is not enough for people to eat, my cheap daddy can't wait to break a grain of grain into two and use it, it is impossible to feed him to pigs, and although earthworms are high in protein, they can be fed to pigs first. Whether it is suitable or not, the amount required is too large, and there is no way to use it as a staple food.

Now it is the limit to be able to feed these ten or so heads.

No matter how much, he couldn't bear it.

The divine book of natural postpartum care for sows is useless for the time being, and we can only wait for the locusts to arrive.

At that time, let alone more than ten pigs.

Even tens of thousands of heads can bear it.

Locusts can be cooked with wild vegetables, and exposed x can be used as a substitute for y rice. If you try your best to catch them, they can both eliminate harm and serve as food. Why not do it?Chongzhen Xinsi, Jiahu dry locusts, m people catch locusts to feed ducks, ducks are very easy to fatten, and people, livestock and pigs in the mountains cannot buy food, try feeding them with locusts, the pigs initially weighed [-] jin, and fattened to more than [-] jin in ten days ....

This is the "Book on Eliminating Locusts" written by Xu Guangqi to Chongzhen, and the meaning is very simple.

Locusts can be mixed with wild vegetables and cooked together; after drying, they can be eaten as dried shrimps. Try to kill locusts to get rid of pests and get food.During the reign of Chongzhen, farmers hunted and killed locusts to feed ducks, and the ducks easily grew fat and big.Feeding pigs with locusts will grow more than 30 catties in ten days.

Li Ming has been staring at this locust plague that made Datang rich.
