However, after Yang Huairen asked about the yield per mu of Lian'er sugarcane and the sugar yield of sugar refining, the answer she got made her overjoyed.

In terms of the yield per mu of sugarcane, the Song Dynasty could not be compared with the later generations, and the later generations had developed biotechnology and had great advantages in the field of cultivating high-yield sugarcane seeds.

At present, there are too few places to grow sugarcane, because the yield of sugarcane is too low, only half of the later generations, and if there is a bad year, it is even only one-third of the future generations.

The extraction level of pressing and other processes in this era is indeed not as good as that of later generations, but because the purity of the frosting in the output is poorer, the sugar yield is two or three percent higher than that of later generations.

According to this calculation, one acre of sugarcane land in later generations can produce 600 to 700 kilograms of sugar, and now one acre of sugarcane can produce more than 400 catties of frosting.

Because sugar is heavier than rice, the unit of measurement converted into market transactions is to produce three stone frosting per mu, so 30,000 acres of sugarcane land can produce 90,000 stone frosting.

Although this figure cannot be compared with the annual output of 10 million tons of sugar in later generations, in the Great Song Dynasty, if all 90,000 stone sugar frostings were sold, it would be a lot of money.

But Yang Huairen suddenly remembered that the current annual output of frosting in the Great Song Dynasty is only tens of thousands of stones, if it is so easy for him to produce 90,000 stones of sugar a year, it can basically be said that the sugar output of the Great Song Dynasty is doubled, is it too easy?

In the current situation where businessmen are everywhere, if there is such a profitable business, it is impossible for others not to do it?

Under careful questioning, Wang Xialian couldn't help but smile, "Official, the account is not calculated like that, our family's 30,000 acres of land can't produce the 90,000 stone sugar frosting you said."

The final product produced in the sugar factory is not frosting, but stone honey, which is the best part of the sugar, and the rest is stone honey.

The gentleman in the college calculated that the final sugar yield of 30,000 acres of sugarcane land should be nearly 10,000 stone of frosting and 5 to 60,000 stone of stone honey. ”

Yang Huairen sighed, his scientific calculations were still wrong, and the gap between the actual situation and the theoretical calculations was really a bit big.

Stone honey is the most common sugar food among the people, and it is a bit similar to the rock sugar of later generations, but the purity is definitely a lot lower, and the color is dark yellow, and the sweetness is average, but it is much cheaper than the purer frosting.

Yang Huairen said to himself, "If that's the case, it's still not enough." ”

Lian'er asked, "What do the officials mean, is we still going to buy land in Lingnan?" ”

Yang Huairen smiled, "That's not necessary, it's really not good to have too much land, even in a place like Lingnan, but others will still find us trouble."

It's different now, the higher your status, the more people are staring at you, it's okay to pretend to be stupid and stupid like before, but now it's enough to choke, no one is really stupid.

What I mean is can we mobilize the local people to reclaim more land to grow sugarcane?

According to the Song law, the land is owned by whoever reclaims it, and there is a five-year tax exemption treatment, and there are not many places suitable for reclamation of land in the Central Plains and Jiangnan.

But Lingnan is different, the land is vast and sparsely populated, and although there are more mountains, there should be many places that can be cultivated into fields.

Let the people reclaim the land to grow sugarcane, and our family will buy it, and the price given is enough, so that they can feel that planting sugarcane is more profitable than growing grain, and they are not afraid that they will not plant.

Our family only needs to be responsible for the acquisition, transportation, transportation and sugar refinery, and it is not necessary to take all the links into our own hands.

The 30,000 acres of land is also enough, on the one hand, we master the planting technology and market, and on the other hand, we also invite some gentlemen of agriculture in the college to guide and do some things like cultivating good seeds. ”

Lian'er thought about it and seemed a little worried, but it was not good to say it directly to make the official's face look bad.

Yang Huairen asked, "What's wrong?" Can't I do it? ”

Lian'er hurriedly said, "No, the official's method is naturally good, but it's a pity that there are not so many people in Lingnan." ”

"Huh?"

Only then did Yang Huairen remember that the current Liangguang area is still a place that has just been opened for a long time, and the population density is extremely low, except for some prefectures and counties with relatively large populations around them, and more places are still mountainous areas and primeval dense forests.

In the exile of the Great Song Dynasty, the most severe was the distribution of Lingnan and Danzhou, because the current Lingnan is still too backward and relatively desolate, and there are still many ethnic minorities living in the surrounding area, which are called Nanban by the Han people.

It's not that people can't survive here, but compared to places like the Central Plains and Jiangnan, Lingnan has a very difficult life.

Not to mention the hot and humid climate all year round, there is too much rain in summer and autumn, and there are often super strong winds blowing from the sea, and natural disasters such as floods and mudslides occur almost every once in a while.

Lian'er said, "Our family's 30,000 acres of sugarcane fields are also insufficient, there are not many Han people in Qinzhou, and there are some mountain people and Nanban in Yongzhou in the west, so we can't find them to grow sugarcane for our family, right?" ”

Yang Huairen was a little helpless, Lian'er said this is not discrimination, because it is indeed as she said, on the side of Guangnan West Road today, the Han people occupy some larger urban settlements, and the larger land is inhabited by mountain people.

The mountain people are also divided into many large and small tribes, they have their own habits and rules, which are completely different from the habits of the Han people, and some mountain people do not obey the education and do not know the etiquette, and the Han people living there treat them as savages, and they rarely come into contact with them.

30,000 acres of sugarcane fields, even if it is an extensive planting method, requires thousands of laborers, but after all, the number of Han people is not large, and it is difficult to make up so many people to work in a short period of time.

This is not counting the labor problem of the sugar factory, even if you hire laborers from the Central Plains to work in Lingnan, it is not an easy task, if it is not for the homeless people who really have no way to live, who wants to go to Lingnan to suffer?

Yang Huairen also understands more and more that Lian'er is in charge of the family's business, which is very laborious, and it is usually Yang Huairen who thinks of an idea and says it casually, so he arranges the specific business matters to Lian'er and the housekeepers to do.

He turned a blind eye to the shopkeeper, but Lian'er wanted to do something, but he broke his heart.

Lingnan is indeed suitable for growing sugarcane, but the problem is that the land in Lingnan is cheap, but there is not enough labor, and some of the people recruited now are recruited from other places to bring to Lingnan to work, and the treatment of people must be very good.

Even so, listening to Lian'er's meaning, there are still not enough manpower, Yang Huairen sighed in his heart that Lian'er was too hard, and he also thought that he could share her worries.

Thinking of this, Yang Huairen suddenly thought of one thing, isn't it going to conquer Jiaozhi next year, the war will naturally produce a lot of refugees, maybe these refugees are the solution to the shortage of labor.
