After two or three days of soaking and germination, the sugarcane has successfully sprouted, which is worthy of the seeds given by the system, but after five or six days, the sugarcane has been able to be transplanted into the ground.

During this time, Gu Lan was not idle for a day, and was getting busier day by day, if Beigang Village wanted to plant sugarcane, it was necessary to re-cultivate the field, and the land that had been planted with grain could not be dug up, so it was necessary to reclaim the new field, and it was not easy to open a new field, just digging the soil and loosening the soil, and disposing of the roots and stones in the ground was a big problem.

Fortunately, Xiaolongkan has built some iron farm tools, and there is no shortage of young and middle-aged laborers, and more than a dozen people take turns to farm, which is not too tiring, and the work is very fast.

Planting sugarcane requires deep ploughing and shallow planting, wide rows and dense planting, and application in advance, and then there is another problem.

There are too few poultry and livestock in Xiaolongkan, and the fertility of farming at this time basically depends on livestock, and the land they plant is small, which is not less fertility, but in the first half of this year alone, the newly reclaimed land in Xiaolongkan has hundreds of acres.

Gu Lan also realized that the village needed to buy some cattle, sheep and donkeys and other domestic animals, and composting was a word, which could also greatly alleviate the disadvantages of labor shortage.

However, in terms of Xiaolongkan's current ability, how many cattle and sheep are needed and how many can be raised, all need to be calculated.

Gu Lan had no choice but to find Li Ergou, he was originally a widower in another village, living by fishing, last year because he lost a boat, he was cheated out of money by the Gu family, saying that he wanted to marry Gu Lan to him, but Gu Lan married Aji, he had no money and no daughter-in-law, this person was thick-skinned, and he had no worries about it, and he left his face in Xiaolongkan, specifically to harm the reputation of the Gu family.

If it weren't for him, it is estimated that the Gu family would not have moved out of Xiaolongkan so quickly.

This person is not without merit, in terms of mathematical learning ability, he is the most powerful person Gu Lan has ever seen in this era.

Li Ergou is a person, as long as he can eat and dress warmly in life, it doesn't matter where he lives, even if it leaks wind and rain, so once he falls in love with arithmetic, he will soon be immersed in this mysterious world that has not yet been set foot in.

Others walked in the village, looking at the mountains and waters, and he looked at the mountains and looked at whom, and all he thought about was mathematics.

Gu Lan was afraid that he would be crazy, and also thought that this was a rare genius, and it would definitely come in handy, so she arranged a place for him to live, live with Liu Banzhu and more than a dozen adopted children, and watched him eat on time, and starved to death.

Li Ergou teaches arithmetic in the village private school, he has not gone to school, but he is very proficient in mathematics, and he is extremely serious when teaching children, and the children in the village still like him.

Therefore, as soon as he encountered something related to mathematics, Gu Lan found Li Ergou and told him about the current difficulties in the village.

If you want to raise cattle and sheep, but you don't know where the upper limit of the village is, the cattle and sheep need feed, and the price of a cow is also very high, the market price is between 22 and 30 taels, and many people need to save three or five years to buy a cow.

What's more, cattle are still a very important production material for the imperial court, and ordinary people are not allowed to buy and sell cattle privately, and they must go to the cattle market in the county government to buy them.

Gu Lan also had an idea, since she wanted to buy cattle, she didn't want to buy ordinary cattle, but wanted to buy buffaloes that could produce milk.

If the children in the village can drink buffalo milk, there is no gap now, but when they grow up, whether it is size or physical fitness, they will definitely be able to widen the gap with the local children.

Li Ergou couldn't answer this kind of question at all, except for "how many cows can meet the milk needs of the children in the village", because he didn't know how much milk a cow could produce.

The other questions gave Gu Lan a perfect answer.

After having the answer, Gu Lan began to search for talents, and asked the people in the village if there were any cowherds who knew cattle, and wanted to ask for help to go to the county to buy cattle together.

Within two days, Ram You found a person for her, an old man.

This old man looks at the age of fifty or sixty years old, and his body is still very tough, which is a rare thing, you know, there is a lack of labor force in this era, many people have to work in the field before their bodies are well developed in their teens, and their waists are tired and bent in their twenties, and their thirties look like fifty or sixty years old in their previous lives, fifty or sixty years old...... It's almost time to be in the ground.

The old man's surname is Niu, I heard that the ancestor was to raise cattle for a certain family, and then the family was gone, and his ancestor's skill in raising cattle was passed down, and he specially treated cattle patients within a radius of more than ten miles, and delivered cattle with boys, and worked for most of his life.

I heard that Gu Lan wanted to buy a buffalo that could produce milk, and the cowherd's eyes flashed, it seems that she has met someone who knows how to do it! Their family raises cattle and is in very good health, just because they often drink milk, they didn't tell anyone this secret, but they didn't expect it to be told by Gu Lan.

Gu Lan planned to buy twenty buffaloes this time, eight old cattle, and many males and females.

He said to Gu Lan: "I have tasted the tofu in your village, I heard that this is a kind of food ground from beans, since it is ground from beans, is there still some residue?" ”

Gu Lan raised her eyebrows, and saw that this cowherd also had something on her body.

Nowadays, people rarely see soybeans, and it is quite powerful to be able to guess that there will be bean dregs when making tofu without knowing it.

The cowherd smiled: "I have dozens of cows at home, I usually want to feed these cattle, in order to find food for them, you can say that you have tried, last year I heard that the kudzu can eat, I think since people can eat, these livestock must also be able to, so I grind the kudzu and feed the cattle, I didn't expect to raise it very well." ”

Gu Lan was a little surprised, it takes a lot of effort for ordinary people to raise a cow, this person actually raises dozens of cows at home, what does this think?

She asked the doubts in her heart, and the cowherd sighed and said, "People say that there is a very smart woman in Xiaolongkan, I didn't believe it before, but when I saw you today, I believed it." ”

"I won't tell you, these cattle in my family are not raised for myself, but the county magistrate, the last county magistrate raised a lot of cattle, I heard that I would treat the cattle, so I asked me to see, and then I moved my mind, and entrusted the cattle in the county government to me to raise, originally the court provided feed, this raising is seven or eight years, replaced by the current county order, he does not give feed, dozens of cattle, a day is to eat a few taels of silver, but someone came to buy cattle, and they have to be taken away from my home."

"If I raise the cow to be sick or die, all of them have to settle accounts with my family, I have four sons under my knees, two daughters, neither of them is married, grandchildren can walk and know to help the family weed and feed the cattle, I have a hard time!"

"Gu Dangjia, since you want so many cows, let me ask you for one more thing!"
