Chapter 1657： Earthworms and eggs

For this October rain, Marin was also taken aback. Because if there is no samarium this year, the harvesting speed will be much faster, and the autumn harvest in the northwestern part of the North Sea will also be affected a lot this year.

However, he dare not guarantee that the North Sea country can avoid the rainstorm during the autumn harvest every year. Therefore, after thinking about it, he decided to dry multi-storey ovens in various towns by drying dehydrated vegetables. Each floor uses a large iron plate with food in it, and it is dried in a room with dozens of degrees. In the event of rainstorms during the autumn harvest, the harvested wheat will be dried in the oven at medium temperature for a long time while organizing the harvest. It should be noted that the temperature cannot be too high. Otherwise, the food will be cooked.

In addition, ordinary people can also build fire-kang in their homes, and use the fire-kang to dry moist food. Therefore, after the end of the autumn harvest, Marin promoted the use of a version of a grass-framed adobe house to completely replace the original broken wooden house, while building fire-kang in each adobe house bedroom.

There are many plants in the countryside, and firewood can be seen everywhere. Therefore, the adobe houses promoted in the countryside all have Chinese-style earth stoves with chimneys, and are wood-saving stoves with thick stove walls.

The reason for this is that in addition to the fact that it is cheaper to use firewood in the country than coal, the wood and ash left over from the stove is also an important fertilizer. In order to prevent the waste of grass and trees, Marin ordered every farmer to build a latrine and collect feces. The grass and ash left over from the daily fire must also be piled up in a small house that does not leak rain. This hut can be a mud hut or a grass hut. In short, it does not need to leak rain. After all, as soon as the plant ash meets water, the potassium component is dissolved and washed away with the water.

Then, every few days, there will be a special agency in the town to send people down to various villages to collect manure and grass ash, and take it back to be processed into fertilizer.

In other words, Marin promotes the use of earthen stoves in the countryside, in fact, to collect grass and ash. Although he now has a potash mine in the Harz Mountains, God knows when the salt mine will be mined. Therefore, collecting some plant ash and extracting potassium salts is just a matter of course. After all, he is also collecting feces, collecting and using grass and ash, but it is a matter of convenience.

It's funny to say that Europeans have long discovered that using grass ash and lime water is mixed, and then reacted with fat to get soap. However, they didn't know that they used ash as fertilizer.

Of course, modern chemistry has not yet emerged, and Europeans do not understand the principle, but just stumbled upon this way to make soap, and did not understand the truth at all.

Marin is different, his middle school chemistry is not in vain. Therefore, he collected the plant ash, soaked the water directly in the pond, then filtered, and extracted less potassium carbonate. In this way, most of the plant ash is useless, so as not to occupy space. When it is necessary to fertilize, the potassium carbonate dissolved water is directly incorporated into the main fertilizer.

In fact, potassium carbonate is the "ash frost" in the ancient Chinese legend, which was extracted from the grass ash by ancient Chinese alchemists. An important role of ash frost is to purify saltpeter. If there are magnesium ions and calcium ions in saltpeter, it will easily absorb water molecules in the air and get damp. After ashes are added, carbonate ions, magnesium ions and calcium ions form a precipitate. The potassium ions and the nitrate combined with the original magnesium or calcium ions form new potassium nitrate, which further improves the purity of nitrite ...

In addition, significant progress has been made in the breeding of earthworms with feces in the North Sea country, and multiple earthworms that like to eat feces are selected. At present, the craftsmen who like to study under Marin are calculating the conversion rate of feces and earthworms, that is, the ratio of how much feces the earthworms eat and how much black earthy feces are discharged.

However, the research on feeding earthworms with feces is still at the stage of horse, cattle and sheep feces. Human feces have not been successfully used to feed earthworms. Because horses, cattle and sheep eat grass, the feces are rich in cellulose, and it is not as burning as human feces. Earthworms eat cow dung, sheep dung and horse dung, and they are very comfortable. But people eat whole grains and meat, high salt, and the environment of manure is very unfriendly. The earthworm eats it and is very uncomfortable, even sick, and needs processing.

But there are no professional scientists in Beihai, so it is a little difficult to transform human feces into a milder one, so that earthworms can eat. Therefore, Marin is now mixed with manure in the fertilizer, and the earthworm feces converted from the feces of cattle and sheep are also mixed. There are also many "black soils" made of human feces that have been dried for a few months.

Once the research on the treatment of human feces is successful, the main body of fertilizer in Beihai becomes earthy earthworm feces, even if it is stolen by foreign spies, it will never be recognized.

...

In fact, because it is still an era of animal power, there are many cattle and horses in Beihai. In addition, the number of sheep is also very large. Therefore, although the total amount of animal feces is less than that of human feces, it is not much.

Therefore, the actual situation at present is that the scale of feeding earthworms with the dung of horses, cattle and sheep has reached a huge scale of millions of pounds. And the earthworm droppings obtained have reached 20-30 million pounds, and the earthworm droppings transformed every day have 300,000 pounds. At present, the breeding center is collecting a variety of earthworms, including those from the Americas, to compare data to select the most suitable species to transform feces.

And recently, those less professional researchers under Marin suddenly discovered that-it seems that pig manure is also a good feed for earthworms. That is to say, most of the feces of domestic animals can be used to raise earthworms. Only human feces may have high salt content, and other factors cannot be directly used to raise earthworms.

This research result is very important because the number of newly introduced Taihu pig populations in Beihai is expanding very quickly. There are more than a dozen births, and they grow fast. As long as there is enough feed, feces are absolutely sufficient. By that time, earthworm droppings are definitely enough.

And ~ www.novelhall.com ~ Recently, earthworms have made great achievements in chicken breeding. The famous laying hens introduced from the Ming Dynasty-Luhua chicken, after eating hot-water boiled and sterilized earthworms, the egg production rate has been greatly improved, and the average egg laying is every two days. In this era, it is definitely a miracle. In general, chickens often lay eggs only once every few days. Moreover, after laying eggs, they like to squat on the eggs and hatch themselves.

Marin established a chicken farm near Aurich and built professional chicken coops. While restricting the movement of the reed chicken, it also feeds the earthworms. Moreover, a special cloth is used to cover the hen's sight, and then take the opportunity to take the eggs. After the eggs are taken away, the Luhua chicken hen will be very confused. Then, continue to eat and drink eggs. In this way, this professional chicken farm provides enough grass eggs for Marin's palace. Every morning, Caesar, Robert, Jack Ma, and Mary eat breakfast with eggs and milk. As for William, because he is too young, he has not been weaned, and he cannot eat eggs ...

Now, as long as enough fertilized reed eggs are hatched in the Kang room, and more reed chickens are hatched, there will be no shortage of eggs in the North Sea. Although it can't keep up with the efficiency of laying eggs every day in later generations, laying eggs once every two days is definitely high.

However, eggs are still very expensive. A dozen eggs (12 eggs) cost 1 Finney, which is half a day's salary for ordinary people, which is equivalent to 50 yuan for later generations. In other words, the current egg is equivalent to more than 4 dollars in later generations, which is really expensive. She can buy a pound of eggs when she rests in later generations. However, it is not surprising to think about the current food prices in Europe ...
