While Li Yu was making arrangements for building a house, he also did not forget to solve the problem of eating.
The food the lizard people brought out from the swamp was mainly some dried meat and wild vegetables, plus the grain stocks and some poultry they grabbed after looting several villages.
This food could probably sustain them for a month, or even longer, but Li Yu still spent money to purchase a batch of grain from Black Rock City, mainly wheat and rye, plus beans and peas.
There are onions, which are also some of the most common foods on the tables of ordinary people in the Red Lion Empire.
In addition, there used to be a lot of farmland on these two pieces of land, and it was almost time to harvest.
Although some of them have been ruined by the lizard people, some of them can still be saved. In addition to the specialty carrots of Green Field, there are also barley and wheat, which are almost mature.
Of course Li Yu didn't want to waste it.
Some time ago, he and Yin Leya made a lot of money selling pepper together in partnership, but now he has spent most of the money in just a few days.
And this is only a small part of the initial investment.
After Li Yu followed Miss Rabbit to her territory, although he seemed a bit unprofessional, he wandered around the green fields with his little maid Clara and a few undergrown children every day.
But it was this valuable experience of field research that gave him a deeper understanding of this land.
Among them, agriculture was especially the focus of Li Yu’s inspection.
Food production is the most important thing at any time and anywhere.
If you have played Don't Starve games, you should know that in the early stages of the game, most of your time will be spent on collecting food to feed yourself, which sounds very simple.
In fact, overproduction is one of the basic conditions for creating civilization.
If you can get the land to produce more food, you can free up more people from the land to do other work.
The level of agriculture on the continent of Bratis is so backward, and the ratio of planting to harvest is as high as 1:4. This is actually the result of various conditions working together.
Putting aside the geographical climate and the species differences of the starting crops themselves (for example, rice in Asia is naturally much more productive than wheat in Europe), factors such as this are temporarily difficult to change.
First of all, there are big problems with the tools.
Li Yu had seen the plows used by farmers in Luye, and they were still similar to the scraping plows used by the ancient Romans.
This kind of plow is made of wood, with blades and iron birches on the head, and can be dragged by humans and animals. However, it can only plow the top layer of soil, and cannot really turn the land, loosen the soil, or remove the roots of weeds located in the lower layers.
Once the seeds are sown, the weeds will begin to compete with the seeds for nutrients in the soil.
Moreover, the number of such scraping plows was pitiful. There were often only one or two in a village, owned by the lord, which was far from being able to meet the farming needs of a village.
Li Yu took the right medicine and planned to introduce the share-type plow. This type of plow actually appeared very early in China, but it was introduced to Europe thousands of years later. It is still widely used around the world. Of course, many of them have been mounted on tractors.
It's over.
Its structure is not complicated, including a share, a soil divider, a plow frame, and a small wheel that can adjust the height.
Among them, the rubber wheels can be replaced by wooden wheels. It is best to use iron for the plows and soil dividing blades. If not, you can even use wood. After all, during the Spring and Autumn Period and the Warring States Period, many plows were made of pure wood, but the effect was less effective.
If you replace the plowshare with a chisel, you can also aerate the hard soil that has been cultivated too hard.
In addition, Li Yu is also planning to buy a seeder. The principle of this thing is also very simple. It is a wheelbarrow that can be pushed by hand, plus a rotating wooden baffle and funnel. As long as the seeds are added from above, the seeds can be evenly distributed.
Sprinkling it on the land can improve efficiency a lot more than planting seeds bit by bit with your hands.
There are also sickles. The short-handled sickles used on the Bratis continent can only cut half of the straw.
And if the handle of the knife can be lengthened, more straw can be cut, and the straw can be used as fodder to feed livestock...
For all of the above tools, Li Yu can easily find suitable models on Taobao.
Use it as a prototype, and then recruit blacksmiths to cooperate with the carpenters in the territory. As long as you try a few more times, you should be able to achieve mass production. In the future, if Li Yu finds other useful methods on Taobao and can use today's Bratis technology,
The replica farm tools will also be moved here.
In addition to backward production tools, the scarcity of fertility is also a major factor.
Most areas of Bratis Continent still use the two-field system, which means dividing the fields into two pieces. Only half of the land is planted every year, and the other half of the land is allowed to rest. The land that was previously cultivated will be replaced in the next year.
Next, work on another vacant land, and so on.
The reason for doing this is to allow the land to rest and restore its fertility.
Of course, the shortcomings are also obvious. The fields are only half utilized, and half of them are empty every year.
Only a few areas with very fertile land will implement the three-bed system.uu看书www.uukanshu.com
This is very similar to the two-field system, except that the land is divided into three parts. Each part of the land is idle for one year and can be cultivated for the remaining two years.
Just a simple calculation can show that the efficiency of the three-field system has been greatly improved compared to the two-field system. The land utilization rate has increased from 50% to 66.7%, and each piece of land can harvest almost 30% more grain.
Unfortunately, not all places are fertile.
Taking the green field where Miss Rabbit is located as an example, we can only adopt a two-field rotation model and forcefully change it to a three-field system. Maybe we can get a bumper harvest in the first two years, but the harvest will get worse and worse in the future, until it is completely impossible to cultivate.
The Church of Silver Moon claims that this is the goddess teaching the people in this land not to be too greedy.
Li Yu knew that the nitrogen in the land had been exhausted.
The solution to this problem is also very simple. Every modern person who has completed nine years of compulsory education can easily tell the answer, that is - beans.
To be more precise, it is rhizobia that live in the roots of legumes. This special bacteria can return nitrogen from the air back to the soil.
Taking advantage of this feature, not only can the land that can only be implemented in the two-field system be upgraded to the three-field system, but it can also be further developed to develop a four-field rotation model.
Moreover, instead of each of the four fields resting for one year after three years, they are all planted with crops for four years. By planting different legume crops every other year, the land utilization rate is increased to 100%.
This was a necessary means for Li Yu, because compared to the land he received, the number of lizard people was obviously more, almost twice as many as the households living on this land before.
If you want to achieve self-sufficiency, you must make good use of every piece of land.
