Working Prophet.

Chapter 97 Banquet Invitation

In addition to growing beans, the aqua toilet that Li Yu asked the designer to design can also come in handy.

These dry toilets can not only prevent the lizard people from urinating and defecating on the church territory, and maintain a clean and hygienic environment, but also collect feces and urine for use in agricultural production.

On the continent of Bratis, farmers also fertilize the land.

The fertilizer they use is mainly livestock manure, in addition to lime and river mud, and farmers in coastal areas will also sprinkle seaweed into the fields.

However, compared to the vast land, the fertilizer they can collect is somewhat limited.

Generally, these fertilizers are thrown into the fields of winter crops, because these winter crops tend to grow better and can be sold at a higher price. As for the summer crops, they generally leave them alone.

Moreover, the methods used by these farmers to use fertilizers are also very primitive, basically dumping the collected livestock manure directly on the fields. In doing so, the fertilizers are often not completely absorbed by the land, and at the same time it is easy to attract underground pests.

As for human excrement, it is generally regarded as filth by the church, and it is not allowed to be used on the farmland on the grounds that it will pollute the crops.

Of course, Li Yu and Saturday behind him don't recognize this, so he must also use human feces.

It's not just those on the territory of the church. Li Yu plans to personally talk to several other nearby villages and ask the villagers there to keep their excrement as well. Then he can send people to buy it regularly.

For a little money, you should be able to get quite a bit of manure.

And Li Yu didn't plan to add these manures directly to the fields, but planned to compost them first.

The so-called composting is to mix the collected feces and urine with straw, weeds, fallen leaves, and pond mud, and then through the action of microorganisms, various complex organic nutrients in it are converted into soluble nutrients and humus, and fermented The high temperature at the time can also kill the grass seeds, germs and pests in it.

Using it as a base fertilizer can not only improve the soil, improve soil utilization rate, but also greatly reduce soil-borne diseases.

There are hundreds of methods of composting. In the north, composting is generally done in a composting shed, and rags, mats or plastic sheets are covered on the compost heap. If there is no composting shed, it is not impossible to be in the open air, but the sun and rain will inevitably lead to reduced fertility.

In the south, more soil pits are dug for retting, and urine and manure, green manure, weeds, stalks and pond mud are put into the pit together and fermented with water.

Li Yu was not sure which of these two composting methods was better, so he just tried both, anyway, it was just a matter of building a shed and digging a hole.

All of the above are means to increase production or improve efficiency that can be effective in the future.

In addition, there is another thing that may not be effective in the short term, but the long-term persistence will increase the benefits, and it is easy to be ignored, that is-breeding.

Like animals, plants in nature are constantly evolving, although their evolutionary process is often not very eye-catching.

However, the same plant is often very different from thousands of years apart.

For example, the corn 9000 years ago was only one-tenth of its current size, and there were less than ten corn kernels on one corn. If you want to fill your stomach with this kind of corn, you may have to buy thousands of them.

What is even more outrageous is watermelon. The length of watermelon before 5000 years is only 5mm, and it has a hard shell like a walnut. Under this shell, it is full of fat and starch. It is not easy to get a sweet taste from it.

Although most of the plants on Bratis Continent are familiar to Li Yu, there are still many gaps with those in modern society.

Wheat, oats, rye, and the carrots that the Arias family has been growing in large quantities are far from what Li Yu usually eats in terms of yield and taste.

It's a pity that he couldn't bring the seeds of another universe, otherwise, if he planted any kind, the original crops of this universe would have no way to survive.

But Li Yu didn't have to wait for thousands of years like he did in the original universe.

Now that the knowledge of genetics has been learned in the biology class of junior high school, as long as the targeted selection is used, artificial intervention can be performed, which greatly speeds up the process.

The most famous example of this is hybrid rice.

Academician Yuan Longping, who is known as the father of hybrid rice, developed the third-generation hybrid rice "Sanyou No. 1500". The combined average yield of early rice and late rice has even exceeded [-] kilograms per mu, which can be called a biological miracle!
He has fed 7% of the population with 22% of the world's arable land, and it took him only a few decades to do this.

It's a pity that there is no rice on the Bratis road, and it is not so easy to find male sterile lines, so Li Yu can't directly copy homework.

But he has always attached great importance to breeding.

In fact, Li Yu had already started to do this not long after he arrived in Luye. He entrusted Miss Rabbit to find four boys and girls for him.

Among the screening conditions given at that time was the best farming in the family.

Later, Li Yu also taught them Arabic numerals, just to facilitate their future statistical research.

And not long ago, Li Yu had already given them the first task, asking them to pick out the ones with the highest yield, the best appearance, or the ability to resist pests and survive in harsh environments. Specialty crops grown under.

Collect their seeds and record their characteristics.

Li Yu will set up several experimental fields on the territory of the church to plant these special crops, continue to select plants with other outstanding characteristics from their descendants, continue to cultivate them, and promote them at the right time.

This process is a bit like swiping entries. It takes patience and a little luck to flash red entries.

But once you get good entries, such as cold resistance, drought resistance, and salt and alkali resistance, and successfully keep them, you can definitely make a lot of money.

…………

The agricultural revolution initiated by Li Yu is bound to have a profound impact on the progress of civilization on the continent of Bratis.

But like all great changes, in the beginning, not many people noticed.

People's eyes still linger on those great figures and their decadent or boring daily life. The love and hatred of those nobles can attract many topics with every move.

And if you want to say who is the most influential person in the entire western region recently, it has to be the new head of the Arias family, Ilea.

The Arias family, located in the backcountry, has always been low-key. It has been a long time since there have been any amazing and brilliant people, or have done any great achievements worthy of special mention.

However, recently, it has been uncharacteristically. First, the matter of choosing the head of the family went to the Marquis of Cullen, and then he took the initiative to disclose the election process, and there were twists and turns, and mysterious foreigners appeared on the stage and performed miracles. It can be said that it has earned a lot of attention.

It is said that the two candidates fought a battle after returning to the territory. Seeing that the outcome was decided, everyone thought that the good show was about to end. No one expected that Ilea, who had just taken office, had another wave of orgasm.

The Patriarch of Arias appealed to the Marquis of Cullen and other nobles in the western region for help overnight, claiming that he had encountered a large-scale attack by the Lizardmen, and begged them to send troops to help rescue the innocent people who were trapped in the Teacup Castle. a group of people.

But before the families could figure out the specific situation, just one day later, Ilea withdrew her request for help, saying that the crisis had been resolved.

When receiving the letter, the heads of many families turned into question marks, wondering what the writer wanted to do, and after half a month passed, the new head of the Arias family seemed to remember, After inheriting the territory, he has not held a banquet yet.

So he wrote to a group of nobles in the western region, inviting them to come to his territory as guests.
