After ploughing the land, it's time for the columbus show. The efficiency of the columbone is higher, and it can sow forty or fifty acres of land a day, and the efficiency is so high that it is a mess. Then, when spring planting and sowing are over, it will start in April. In other countries, spring ploughing has just been carried out in a small part.

Seeing that the whole country had the intention of resting, Marin felt that it was a bit of a waste. Suddenly, he remembered that he could plant grass!

The so-called grass planting does not refer to planting the grass for greening in later generations, but planting pasture. It's mainly alfalfa grass, but also ryegrass.

Ryegrass is not rye, the two are two things. Rye, also called triticale, is a food crop. Ryegrass, on the other hand, is pasture grass and belongs to something else.

The most powerful thing about ryegrass is that it grows more than a year. That is, it can be harvested several times a year. Of course, it is also possible to graze directly and let the cattle and sheep graze on the ground. After eating, rush to another place. After a few months, the ryegrass grows back and can be grazed again.

Therefore, in later pastures, ryegrass and alfalfa were generally used for mixed sowing. In Australia, for example, alfalfa and ryegrass are commonly used for mixed sowing.

Why mix it with alfalfa? Because, alfalfa is a leguminous crop and can fix nitrogen. Planted with alfalfa, it can fertilize the ground. Ryegrass, on the other hand, is a crop that consumes land power. Growing ryegrass alone even requires fertilization.

The alfalfa and ryegrass in the fertile land are mixed so that the effect of alfalfa in nitrogen-fixing fertilizer can be used to "wrap up" ryegrass at the same time. In this way, there is no need to fertilize the pastures. Moreover, alfalfa itself is a top-notch high-quality pasture.

……

It's just that most of the grasslands in Beihai are native weeds, and the animal husbandry effect is not good. Cattle and sheep eat it, and it is difficult to gain weight.

That's why Marin came up with the idea – why not take advantage of spring ploughing and plant alfalfa and ryegrass as much as possible on the land that has been reclaimed for farmland?

Alfalfa nitrogen-fixing fertilizer, ryegrass can provide multiple rounds of forage for livestock. As long as the pasture planting is done well, Beihai can raise more horses, cattle and sheep in the future.

Moreover, these professional forages are rich in nutrients, and can also be used as feed, instead of grain, to raise horses......

In addition to this, Marin is also going to rotate. There is enough land in Beihai Country, but it is very laborious to grow grain on one piece of land one by one. Although there is a complete fertilizer technology with three fertilizers, it is not as fertile as the land itself.

Marin's plan is to rotate crops with arable land and grassland. He plans to create equally large or even larger meadows around the cultivated land and mix alfalfa and ryegrass. With alfalfa's function of fixing nitrogen and fertilizing the land, after a year or two, the grassland will become fertile.

The cultivated land on the edge is barren because of the consumption of fertility. But it doesn't matter. After a year or two, arable land and grassland are exchanged. The original meadows were used for food, while the original arable land was planted with alfalfa and ryegrass. In this way, the strength of the earth is maintained.

Moreover, the grassland planted with professional pasture can also allow farmers to raise horses, cattle and sheep on a large scale. Among other things, there was an ample supply of fodder for horses used to cultivate the land.

You know, although the Mongolian horses in Eastern Europe eat a lot of grass. However, eating professional and nutritious pasture grass is not the same thing as eating weeds in general. If you eat too much weeds, the horse will grow thin and tired. And if you eat grass every day, you will be fat and strong. When the farm is busy, pulling the plow and the cart is also more powerful.

……

So, Marin ordered the farmers who had finished spring plowing and spring planting to continue plowing the land on the edge of the farmland and use it to grow professional pasture.

Why plough the land? Because the weeds that were in place were to be killed. If the soil is ploughed, the roots of those weeds will be exposed to the air and endure the spring cold. Then, freeze to death.

There are no herbicides these days, and if you want to get rid of those weeds, you have to do this. After the weeds freeze to death, they are mixed with alfalfa grass and ryegrass. In this way, the original uh weeds can be replaced smoothly with professional pastures.

At the sound of the order, the peasants continued to move and continue to plow the fields on the edge of the fields.

But after plowing the land, Marin discovered an extremely embarrassing thing - he did not have enough grass seeds......

This era was not the era of highly modernized animal husbandry in later generations, and the Europeans of this era did not pay attention to the cultivation of professional pasture at all. It is only in Beihai that a lot of alfalfa has been cultivated and there are a lot of alfalfa seeds in reserve.

However, this reserve is really insignificant compared to the huge Beihai Kingdom. You must know that there are 12 million acres of cultivated land in Beihai State. If the crop rotation system is followed, at least 12 million acres of pasture land need to be planted.

However, the alfalfa seeds in Beihai are only enough to sow 1 million mu, which is less than one-tenth of the demand.

As for ryegrass seeds, there are quite a few on the English side. Because, England mainly relied on ryegrass to raise sheep. But Marin sent people to buy it, and he only scraped together enough to plant 1.2 million mu. After all, there is only a lot of wild ryegrass in England, and ryegrass is not deliberately cultivated and cultivated, so the number of seeds is limited.

Then, Marin was embarrassed - more than 10 million acres of grassland were ploughed in China, and as a result, only 2.2 million acres of seeds could be provided......

In desperation, Marin had no choice but to order the sowing of some grain seeds on the seed-poor land. Originally, he wanted to sow rye seeds. However, in consideration of the needs of animal husbandry, on more than 9 million acres of grassland, Marin ordered half of the rye seeds and half of the oat seeds to be sown.

There are too many rye seeds in Beihai Country, and the warehouse is full of them. As for the oat seeds, Marin specially sent people to other countries and regions to buy a lot of them and use them to sow them.

Because it is a sowing, not a scientific and reasonable seeding. Therefore, Marlin did not expect much yield on these ploughed meadows. Fortunately, whether it is rye or oats, the vitality is very tenacious. When the time comes, there will be some gains......

Anyway, whether it's these extensively cultivated rye or oats, they are used to feed livestock. It is best to have the best yield, and if not, the straw is chopped and fed to the livestock......

But because of the embarrassment of this year, Marin specially ordered the formation of the Beihai National Seed Cultivation Base, and began to cultivate alfalfa and ryegrass seeds on a large scale for the next year.

In the future, Beihai will use professional alfalfa and ryegrass mixed planting technology to gradually transform most of the barren grassland in Beihai into pasture.

In this way, farmers can raise a lot of horses, cattle and sheep while farming. Even the harvested grass can be used to feed the pigs.

If it is used to raise horses, with silage technology, horses can be raised to be fat and strong. In the event of a war, all estates can draw a group of fat and strong military horses to use in the war.

In addition, these meadows, which are mixed with alfalfa grass and ryegrass, can be exchanged with arable land to become fertile arable land. The two rotate every two or three years, and agriculture and animal husbandry are correct.

Even, with enough pasture, Marin plans to make it mandatory to raise cows or sheep on all estates in the future. In this way, every child on the farm can drink highly nutritious milk or goat's milk......

At that time, the North Sea Kingdom will be like the Netherlands, which was extremely developed in agriculture and animal husbandry in later generations, because the people have an abundant milk source, resulting in everyone being tall and strong. In this way, in the event of war, the Beihai Kingdom can also pull out a large number of tall and strong soldiers. If you fight with a bayonet, you will have an advantage in height and hand length. The devil soldiers of later generations have such good military literacy and strong stabbing skills, but when they encounter the Northwest Army's broadsword team, they still suffer. Without him, it's not a matter of ability, it's a matter of insufficient height and arm length. No matter how good the technology is, with a height of more than 1.5 meters, in front of the strong men with long hands in the Northwest Army, they will still suffer. Only when they shoot at each other do the devils have the upper hand......

Even in the face of the eight roads that are not very professional in stabbing, the devil does not have the upper hand. At most, they can rely on powerful technology to inflict great casualties on the Eight Roads. But in the end, it's still the devil who suffers. Why? The veterans who have been trained for many years are not the same as the militia randomly recruited from the countryside by the Eighth Road, and the training cost is not the same at all. Even if the casualties are equal, the devils have suffered a big loss. There is no way, the height is not enough, the arms are too short, and fighting with a bayonet is a loss. Even if the technique is good, people can compete with you by relying on their hands.

Therefore, after World War II, the devils were ruthless, and the whole people drank milk and ate beef. As a result, in the 21st century, the height of the devil is about the same as that of the Chinese, and even slightly surpassed.

And in World War II, according to the height, you can judge the origin of the devil. For example, when he sees a group of tall devils, the commander can conclude that this is not a local devil, but a second devil in Goryeo. And a group of devils who are 1.5 meters tall or 1.6 meters tall...... Well, local devils, it's more difficult to do...... The devil played by Mr. Pan, although he is more stupid and does not conform to the facts, but his height is not lying. Even, Mr. Pan's height is a very standard height among the devils during World War II. Otherwise, the devil would not have been called a "little devil" at that time......
