In fact, Silence doesn't teach too much esoteric knowledge in class. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Just tell them that it will be this way, but without saying why, simplify the lesson.

Generally, in 3 to 5 days after composting, the organic matter in the compost begins to be decomposed by microorganisms to release heat, and the temperature in the compost rises slowly, and after 7 to 8 days, the temperature in the compost rises significantly, up to 60 to 70C, especially in the southern part of Liuqiu Island, when the temperature is still high.

Quietly and easily gave them a lesson, saying, "When the compost gets hot after seven or eight days, you can use a long iron rod to stick it into the pile, park it for five minutes, and then pull it out and try it with your hands."

The hand feels warm about 30C, feels hot about 50C, and feels hot about 60C or more.

Then observe the wet and dry conditions of the surface where the iron rod is inserted.

If it is in a moist state, it means that the water is appropriate; If it is dry, it means that there is too little water, and you can make a hole in the top of the pile to add water.

Within 25 days, it is necessary to turn over the pile once, turn the outer layer to the middle, turn the middle to the outside, and add an appropriate amount of feces and urine water to re-accumulate to promote decay.

After re-stacking, after another month, the raw materials are almost black, rotten, and smelly, indicating that they are basically rotten.

It can be used, or the cover soil is pressed and stored for later use. ”

After Quiet finished speaking, looking at the reactions of the twenty and a half children, most of them were pretending to be listening, and some were pretending to be taking notes, but Quiet believed that he just wrote it down in his notebook, not in his heart.

Only Feng Zheng was listening with sparkling eyes.

Badaohe Agricultural Base benefited from the good material conditions of this time and space, and through the use of whale bone meal, sambar bone meal or other fish bone meal, fish production and offal preparation, composting, as well as potassium carbonate extraction from plant ash and other backward and primitive technical means, it has barely prepared three types of chemical fertilizers at the primitive level: nitrogen, phosphorus and potassium.

Of course, struvite is a compound type of slow-release fertilizer------

In short, they may have opened the door to modern agriculture and laid a solid material foundation for the rapid development of agriculture in the following decades.

Therefore, the preparation of relevant soil and chemical fertilizers is a kind of "new normal" in agriculture in the Badaohe area, due to various reasons, this kind of work has to be done every month, every day!

Black people in East Africa and Japanese farmers are busy with this every day, they are the main force in the production and processing of soil and fertilizer, and their busy figures have never stopped except for rest days.

There were also many peasants among the miscellaneous soldiers of the Great Song Dynasty, but they had never seen so much preparation work for farming------- but although they had not seen it, they also understood very well that these methods might be useful.

At this time, the Great Song Dynasty farmers and Japanese farmers had already begun to use manure to fertilize their fields.

The rice seed chosen by Zhang Guoan is the early rice seed of this time and space.

The "early rice" and "late rice" in the Great Song Dynasty were not early rice and late rice in the modern sense, but mainly referred to the early and late harvest periods.

Therefore, even the so-called "early rice" is mostly a mid-to-late maturing variety.

Originally, they brought 60 days to mature conventional rice seeds.

Early rice in the Great Song Dynasty was mainly distributed in Sichuan, Jinghu, Jiangdong, Jiangxi, Zhejiang, Fujian and other places in the Yangtze River Basin.

From the original intention of choosing early rice cultivation in these places, it is first and foremost aimed at drought resistance, especially avoiding autumn drought.

At this time, there is a proverb, "He is afraid of autumn drought, and people are afraid of old age and poverty."

Badaohe agriculture guards a Badaohe, but it is not afraid of this, Zhang Guoan likes that its yield and maturity period can be faster than other seeds.

Of course, they had to reduce the number of varieties when they traveled over, so the main seeds still had to rely on this plane.

Zhang Guoan plans to plant second crop rice or other dry crops such as soybeans and broad beans after the early rice harvest.

In terms of the arrangement of agricultural areas, he divided them into paddy fields, dry fields and hillside areas according to the topography.

These half-grown children don't understand, why should all crops be seedled?

Even wheat seedlings are raised?

They chose spring wheat seeds from this plane.

Wheat was rarely grown in the south, and it was gradually spread to the south after the Han Dynasty.

It was mainly spread by the peasants themselves, and sometimes by the dynastic government or magistrates.

In the early years of the Southern Song Dynasty, a large number of northerners migrated to the middle and lower reaches of the Yangtze River and Fujian, Guangdong and other provinces.

The northerners were accustomed to eating wheat, and the sudden increase in the demand for wheat led to a sharp rise in the price of wheat, which stimulated wheat production. As a result, the cultivation of wheat spread rapidly.

The growing seasons of wheat and rice are different, as long as the arrangement is good, you can plant wheat after harvesting rice in autumn, and transplant rice after harvesting wheat in summer, and the same field can be double-cropped in a year.

The shrewd farmers of the Great Song Dynasty found that the popularization of wheat did not hinder the cultivation area of rice, and they began to be very enthusiastic, and after more than 100 years of development, the south has a considerable level of technology for wheat planting, and the yield per unit area is relatively high, which is not worse than that of the north.

So in the eyes of these half-sized people, wheat is not a new thing.

Spring wheat is the first to be planted in the Badaohe agricultural area, and because of its well-developed root system, it is necessary to be extra careful not to damage the roots and leaves when taking it out of the seedling field.

The half-sized ones are responsible for taking seedlings and sending seedlings, and the miscellaneous soldiers of the Great Song Dynasty are responsible for cultivation, doing it, some of them are really annoyed, and said to Zhang Guoan's main family: "Zhang's family ------ potatoes, sweet potatoes, corn, we have not seen it, we may want to raise seedlings, rice seedlings are also a common thing, but wheat is definitely not to raise seedlings, we have never seen it!" ”

Zhang Guoan smiled, these sweaty half-sized children are really not afraid of hardship, I heard that when they worked in the wood processing factory and bamboo processing factory, they were even happier than the craftsmen of the Song Dynasty!

They're dry, and this one really needs to be sharpened.

He said mysteriously: "Wheat seedlings are not only raised to increase yields, but also have an important use, that is, to train the carefulness and endurance of a gunner when the seedlings are raised!"

I ask you, will a hunter who does not have care and stamina succeed in hunting wild beasts? ”

Of course not, it's common sense!

The half-boys laughed and said, "We have been squatting in the grass for two hours!" ”

Zhang Guoan pretended to be profound at this time: "Therefore, in Yindi Anguo, an excellent arquebusier, he must know both workers and peasants, and he must also take classes to study------"

Oh, it turns out that the lords have good intentions!

The half-size children are the half-sized children, and their labor momentum came all of a sudden, and they actively devoted themselves to the spring plowing and production in the Badaohe area.

In the plan of the six space-time smugglers, after they completed the spring ploughing production, the other four people will go back, after all, earning money is the highest requirement for everyone now.

For them, it is no longer possible to make money by taking the right path, and they can only rely on such an evil path.

Many of the systems that can make you rich are not designed for them, they are for others.

The 3,000-odd men began their final busywork, each of them turning around like a Dutch-style windmill.

This guy's efficiency is really far higher than that of a water wheel.

The craftsmen of the Great Song Dynasty immediately understood the benefits of transverse shaft transmission, which was labor-saving and stable!

The second windmill was immediately put into construction, and Wang Defa didn't have to worry about it.

Just when he thought he could save himself, something happened again.

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

One of the soldiers who accompanied Huang Zu to recruit the indigenous labor force ran back crying.

Huang Zuxiang and his first cadres were detained by a tribe and asked to exchange them for fine cotton and linen and iron tools.

After hearing this, Wu Dapeng didn't know whether to cry or laugh.

In front of those who are bent on violent robbery, no matter how talented people are, they will not be able to display their abilities.

What else can I do, save people!

Things have changed a bit, and in the final analysis, it is still related to Huang Zu's head.

Last year, Huang Zuxiangshou captured more than 70 natives who stole upland rice on the main island of Pinghu, which was the main force of a tribe, but he was lured by Wu Dapeng and stayed here to carry coconuts every day.

The word handling is used very accurately, because there are so many coconuts in this time and space, and Wu Dapeng also said that whether it is landed or fresh, it is needed here.

Wu Dapeng is also thinking about burning activated charcoal with coconut shells.

There are not many people left in those indigenous tribes, and it doesn't matter if it doesn't matter, but I don't know where a bunch of aborigines came from!

The two sides also did not understand the language, but the people were ready to rob them, so they killed the tribal chieftain, and killed the remaining young and strong, the old, the weak, the sick and the disabled, leaving only women and children.

In a jungle society, equality of power is the only element that can live in peace, without which slaughter and enslavement can occur at any time!

As a result, Huang Zu didn't know that he was still taking people to recruit labor, and he thought it was a small matter.

Of course, no one knows about this tragedy.

The victorious chieftain on the other side saw the cotton, linen, and ironware they had brought, and his eyes lit up.

It doesn't matter if you don't understand the language, robbery is something that everyone understands.

They were detained at that time.

In fact, Huang Zu's head was actually carrying a weapon, and he had also made certain defensive preparations.

But I didn't expect that the other party had changed, and the method had also changed, and when they were surrounded by more than 200 people at once, they could only surrender, and the other party was also young and strong.

The chief looked at Huang Zu's clothes, liked it, and took it off on the spot; I looked at the boat they were on and had an idea.

At that time, he gestured to the first few people of Huang Zu's chamber, and pulled out one of Huang Zu's subordinates, and compared cotton, linen and iron.

Finally, try to put your hands in a circle, meaning so many things.

At that time, his people all saw it, and made a sound of "poo, poo, poo", and they were extremely happy!

Of course, the entourage can see it------

Wu Dapeng hugged his shoulder with one hand and chin in the other hand and patiently listened to the cry of the entourage.

Finally he asked, "How young and strong can you think they are?" ”

The attendant said that it was 200 at one time, and 500 at another, and was completely frightened.

Well, Wu Dapeng deduced from common sense that this bandit group is a tribe, they live in the mountains, if they rely only on the agricultural level that can only grow upland rice and they can only use extremely rudimentary hunting tools------ these sub-natives will not dig traps now!

Their ability to survive is very low, and they lack the ability to sustain the size of a population, so a tribe will never exceed five hundred people!

The six of them discussed it and decided that they should tell the natives who were moving it.

When rescuing, it is still necessary to take them as the main force, of course, to give them great help------ at present, these natives are all people who have finally received their worldview education, although there are not too many, but it is not easy.
