With such a strong demand, Zhenbeicheng is naturally going to produce at full capacity. Fortunately, Surunwo has been vigorously developing agriculture in the northern wasteland in the past few years. The entire Beifeng Principality has now reclaimed more than one million acres of farmland.

Of course, this number is not much compared to farmland in other countries, or even far lower. Calculated in terms of population, 600,000 people, 1 million mu of farmland, an average of less than 2 mu per person. If it is a past life, the output of a few acres of land is enough to feed a family, but this is in the middle ages when technology is backward.

Normally, even if you have a high-yield crop like potatoes, you need 30 acres of land to feed your family. If you include all kinds of taxes, this amount is estimated to increase by 50 acres.

After all, the price of potatoes is not high. If you want to make money, you need to grow crops such as oats and wheat, and the lord only collects a small portion of the potatoes. Most farmers in this world grow potatoes for their own consumption, and more often grow wheat, barley, oats and other crops.

The yields of these three crops are not high. The reason why Zhenbei City can now grow a large number of various crops is because the yield per mu here is surprisingly high.

Originally, the land in the northern wasteland was relatively fertile. Coupled with the harvest altar, the yield of wheat per mu in Zhenbei City could reach 600 kilograms.

Although there is a big gap between the yield of 600 catties per mu and the casually yielding 1,000 catties per mu in the previous life, the yield of more than 1,000 catties per mu can be achieved through professional breeding and the action of various chemical fertilizers in the previous life. There is no such thing in this world. fertilizer.

Under normal circumstances, the yield per mu of farmland in the southern provinces is generally about 300 catties, while in the north it is about 250 catties, and even many barren land is only 200 catties. The farmland here in Zhenbei City can reach an output of six hundred jin. It is a miracle in this era.

The main function of this is naturally the harvest altar. In addition to the harvest altar, Sulun also established a farmyard fertilizer factory. The manure produced every day in Zhenbei City will be collected and transported to the farm manure factory for fermentation.

After fermentation, it will be sent to the farmland. Although the fertility of farmyard manure is not as good as chemical fertilizer, it is finally better than no chemical fertilizer. With the help of farmyard manure and harvest altar, Zhenbei City not only grows grain, but also grows a large number of various cash crops.

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

At the same time, the sweet tea dregs are combined with wheat bran and soybean meal left over from the soybean oil extraction. Re-pulverized and mixed is only a very good feed. Centaur has now raised hundreds of thousands of horses, cattle and sheep. The demand for these feeds is very strong.

Among them, the best horses are used as war horses for the northern city of town. The second-class horses will be sold to other countries. However, even the second-class horses are also excellent war horses. Usually these war horses are used by heavy cavalry, and the second-class horses are used by heavy cavalry. Horses will also be sold as war horses, and these horses will be used as normal war horses. The remaining horses are used as horses and pack horses. Zhenbei City now has horse farming besides cattle farming.

Some of the other cattle are used as farm cattle, and some are slaughtered as beef cattle to supply the needs of the North Wind Principality. Because of the prosperity of business, Zhenbei City consumes a lot of beef every day. Cowhide is also a good thing and can be used to make leather armor or other leather products.

The beef tendon is collected and made into various bowstrings. It can be said that the value of a cow has been tapped to the limit here.

Not to mention sheep. The north is cold. Sheepskin is an important tool for the civilians here to keep out the cold. Su Lun even wants to develop the wool textile industry, but Su Lun knows nothing about wool textile technology and can only be handed over to those half-elves with textile experience. Conduct research.

A large number of cattle and sheep have enriched the meat of the North Wind Principality, and the manure produced by these cattle and sheep is also sent to the farm manure factory for fermentation. It can be said that the North Wind Principality has now formed a good ecological chain.

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

The planting area of ​​sugar beet is actually insufficient. During this time, sugar shipments have doubled several times, part of which is the previous inventory of Zhenbei City, and the other part is the real output.

Therefore, when planting sugar beets this year, Zhenbei City once again expanded the sugar beet planting area, and in the following years, the sugar beet planting area will continue to expand.

In addition to sugar, the production of wine and white paper in Zhenbei City will continue to expand. The wine is simpler, because rum is brewed with caramel, which is part of the remaining sugar, and the yield of white sugar increases, so the output of rum is natural. Will also improve.

As for vodka, the sales volume of this spirit is average 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 was favored by the nobles. In order to produce paper, Su Lun cut down a lot of trees near Jinghu City, and at the same time planned to plant bamboo. Bamboo grows fast and contains rich fibers. It is far more suitable for papermaking than grass and wood.

Sulun intends to grow bamboo in large quantities as a raw material for papermaking. UU reading www.uukanshu.com surprised Su Lun. Originally, he thought that the most popular paper should be all kinds of writing paper, but what surprised him is that the sales of these writing papers can be said to be very poor.

The sales volume of toilet paper, which he is not optimistic about, keeps rolling upwards, which is simply unexpected. For this matter, Suren deliberately asked those merchants who bought paper. According to them, writing on paper has a short storage time, is easily damaged, and is not as strong as parchment paper.

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

So they just ignored the advantages of paper. Regarding this approach, no matter it was speechless, these nobles were like those ancient families in the previous life of China, and they completely wanted to monopolize knowledge.

After understanding the reasons why writing paper is unpopular, Su Lun is also helpless. The opposite is the popularity of toilet paper. In the past, the nobles who used ropes, sticks, leaves and other items decisively discarded those things after trying toilet paper. What made Su Lun laugh is that papermaking did not bring about the spread of knowledge, but started the toilet revolution.
