Chapter 666

With such strong demand, it is natural for Beicheng town to produce at full power. Fortunately, sulun wo has vigorously developed agriculture in the northern wasteland in recent years. The whole Beifeng principality has reclaimed more than one million mu of farmland.

Of course, this figure is not much compared with farmland in other countries, or even far lower. According to the population, there are 600000 people and one million mu of farmland. On average, one person is less than two mu. If it was a previous life, the output of a few mu of land would be enough to feed a family, but this was in the middle ages with backward science and technology.

Normally, even with potatoes, a high-yield crop, it takes 30 mu of land to feed a family. If you include all kinds of taxes, it is estimated that this amount will increase by 50 mu.

After all, the price of potatoes is not high. If you want to make money, you need to plant oats and wheat, and the Lord only collects a small part of potatoes. Most of the farmers in the world grow potatoes by themselves, and more of them grow wheat, barley, oats and other crops.

The output of these three crops is not high. The reason why a large number of crops can be planted in Zhenbei city is the amazing yield per mu here.

Originally, the land here in the northern wasteland was relatively fertile. In addition, due to the harvest altar, the wheat yield here in the north town can reach 600 Jin per mu.

Although there is a big gap between the wheat yield of 600 kg per mu and the wheat yield of 1000 kg per mu in the previous life, it can reach more than 1000 kg per mu through professional breeding and the action of various chemical fertilizers in the previous life. There is no chemical fertilizer in the world.

Under normal circumstances, the yield per mu of farmland in southern provinces is generally about 300 kg, while in the north, the yield per mu is about 250 kg, and even many barren land is only 200 kg. The output of farmland here in Zhenbei city can reach 600 Jin, which is a miracle in this era.

The most important role is naturally the harvest altar. In addition to the harvest altar, sulun also established a farm fertilizer factory. The feces produced every day in Zhenbei city will be collected and transported to the farmyard fertilizer factory for fermentation.

After fermentation, it will be sent to the farmland. Although the fertility of farm fertilizer is not as good as that of chemical fertilizer, it is better than that without chemical fertilizer. With the help of farm manure and harvest altar, the north town not only grows grain, but also a large number of economic crops.

Among them, the planting area of sugar beet is the highest. After all, the demand for white sugar is too strong, and the residue left after sugar beet squeezing is not useless. These sugar beet residues are still good feed.

At the same time, the sweet tea residue combined with wheat bran, soybean oil and the remaining soybean meal can only be a very good feed. Half man horse city has raised hundreds of thousands of horses, cattle and sheep, and the demand for these feeds is very strong.

Among them, the best horses are used as war horses in the North Town, and the second-class horses will be sold to other countries. However, even the second-class horses are also good war horses, which are usually used by heavy cavalry. The second-class horses will also be sold as war horses, and these horses will be used as ordinary war horses. The rest of the horses are used as pull horses and pack horses. Now there are horse farming in addition to cattle farming in Zhenbei city.

Some of the other cattle are used as farm cattle and some are slaughtered as beef cattle to meet the needs of Beifeng principality. Because of the prosperity of Commerce, a large amount of beef is consumed in the north town every day. Cowhide is also a good thing. It can be used to make leather armor or other leather products.

Ox tendons are collected and made into various bowstrings. It can be said that the value of a cow has been excavated to the limit here.

Not to mention sheep. It's cold in the north. Sheepskin is an important cold proof tool for civilians here. Suellen even wants to develop the wool textile industry, but Suellen knows nothing about wool textile technology and can only give it to semi elves with textile experience to tackle key problems.

A large number of cattle and sheep enrich the meat of Beifeng principality. At the same time, the feces produced by these cattle and sheep are also sent to the farmyard fertilizer factory for fermentation. It can be said that Beifeng principality has now formed a good ecological chain.

After several years of development, Beifeng principality has become very rich in food at least. However, in order to continue to expand maritime trade, the area of various food crops in Beifeng principality will continue to expand.

In fact, the planting area of sugar beet has been insufficient. During this period, the shipment of white sugar has doubled. One part is the previous inventory in Zhenbei City, and the other part is the real output.

Therefore, when planting sugar beet this year, the planting area of sugar beet in Zhenbei city will be expanded again, and the planting area of sugar beet will continue to expand in the next few years.

In addition to white sugar, the output of liquor and white paper in Zhenbei city should also continue to expand. Liquor is simpler, because rum is brewed with caramel from the rest of white sugar. With the increase of white sugar output, the output of rum will naturally increase.

As for vodka, this kind of liquor is generally sold in the south, but it is very popular in the north. Now, in addition to these two kinds of drinks, Zhenbei city has also begun to brew ice wine, barley beer and other drinks, but the output of these drinks is still low.

Paper is popular among the aristocrats. In order to produce paper, Su Lun cut down a large number of trees near Jinghu city and prepared to plant bamboo. Because bamboo grows fast and has rich fiber, it is far more suitable for papermaking than grass and trees.

Sulun plans to plant a lot of bamboo as raw material for papermaking. To Su Lun's surprise, he thought that the most popular paper should be all kinds of writing paper, but to his surprise, the sales of these writing paper can be said to be very poor.

However, the sales of toilet paper that he was not optimistic about kept tumbling upward, which was unexpected. For this matter, sulent deliberately asked those businessmen who bought paper. According to them, writing on paper has short storage time and is easy to damage. It is not as strong as parchment.

As for Su Lun's statement that the paper is cheap and the paper with the same weight records more words, which is more conducive to the dissemination of knowledge, this statement was ridiculed by those businessmen. According to the merchants, those nobles are unwilling to let more people master knowledge. It is best to master knowledge in their hands.

So they directly ignored the advantages of paper. For this practice, no matter for a while, these nobles are like those aristocratic families in ancient China in previous generations. They completely want to monopolize knowledge.

After understanding the reasons why writing paper is not popular, Suellen is helpless. On the contrary, toilet paper is popular. In the past, those nobles who used ropes, sticks, leaves and other items resolutely threw away those things after trying toilet paper. What made Su Lun laugh and cry was that papermaking did not bring the dissemination of knowledge, but opened the toilet revolution
