Carpenter Li didn't have any copper coins in hand, so he had to take the silver back, "Then I'll take it, if you have something in the future, just look for me, don't be polite to me." I just don't sleep all night, and I'll do it for you. ”

Liu Paner smiled: "Thank you, uncle." ”

She received so much reward from His Majesty, so she should not be too harsh on the price of other people's things. They are all from the village, and they are not outsiders.

When Carpenter Li makes money, he will also build a house and buy a house, and he will also spend money in the town. When the time came, she earned her money back.

The people in the village were very curious when they saw that Liu Paner's family had such a good seedling horse. They didn't make that much, but a family of two horses could still afford it. When planting rice, take turns to sit and everyone can rest for a while.

This kind of farming tool is only spread in Jixiang Village, because only the villagers of Jixiang Village, under the influence of Liu Paner, raise seedlings and transplant seedlings. In other villages, it is still according to the previous extensive planting method.

However, Carpenter Li was not discouraged, and when Liu Paner's rice yielded high again, and the double-cropping rice was successfully planted, the seedlings and horses would inevitably sell well.

It used to take six days to complete the transplanting, but now it only takes five days to complete the transplanting, which greatly improves the efficiency of transplanting.

After the rice planting, Liu Paner has to go to the field every day to see the growth of the seedlings. The same is true for Village Chief Li and Li Dashan.

Li Dashan's family was also planting seedlings, but slowly, so he came to Liu Paner's rice field to inspect the growth of seedlings.

Far away, Liu Paner saw Li Dashan pointing at her family's land.

Li Dashan saw Liu Pan'er and said in a surprised voice, "Yuanqing's family, you see, your family's rice seedlings are alive, they are all alive." ”

Liu Pan'er nodded, "Yes, the effect is good, but there are still a few places, the rice seedlings have not been planted well, and they are floating, and I have to pull out the rice seedlings later and come over to make up for them, so I can't waste the land of this plant." ”

"Yes, it needs to be replenished." Li Dashan should go down and keep it in his heart. More confidence in rice planting.

Village Chief Li didn't say about the paddy fields, but looked at the dry fields in the distance, "Yuan Qing's family, you see that those rapeseeds are about to ripen, when can they be harvested?" ”

"In a few days, you'll be able to plant the seedlings." Liu Paner replied that this is rapeseed with a high oil yield.

Li Dashan smiled, "This rape is good, and the seeds are very large." Sold directly to the oil mill, although the price is okay, but I don't think it's cost-effective. ”

Village Chief Li raised his eyebrows, "Dashan, do you still want to build an oil mill in the village?" ”

Li Dashan nodded, "What is there to dare to think about?" Let's sell rapeseed to the oil mill for only five cents a pound. We buy oil, but it costs forty wen a catty, which is eight times the difference, and there is no rape cake meal. If there is an oil extraction workshop in our village, it is not only convenient to eat oil, but also the scraps of rape cake can also be used to feed pigs, chickens and ducks, and be used as fertilizer. ”

"Extracting oil, it's tiring." Village Chief Li shook his head, he didn't think it was a good job, "It's all about manual pressing, in short, it's not that easy." ”

Hearing this, Liu Paner smiled: "I want to find a way to see if I can make a light and labor-saving oil extraction method." Now every household raises pigs, has rape cakes to eat, and saves feed. In addition, I heard that rapeseed cake is fermented and used as fertilizer, and it is particularly fertile. ”

Hearing that Liu Pan'er wanted to find a way, Village Chief Li's eyes lit up, "Yuanqing's family, do you really want to get an oil mill?" ”

Liu Pan'er nodded, "I really think, Uncle Dashan was right just now, the price of oil is too expensive." It's okay if the family is rich, and put some oil in the stir-fry. If you are not rich, put a few drops of oil. How can a dish stir-fried like that be delicious? If there is an oil mill, at least every household has rapeseed, and it is more cost-effective to come and extract oil, pay wages, or change the oil, than to change the oil from other places. ”

Just do it, Liu Paner got home and began to check the books.

Rapeseed oil extraction, first of all, we must be clear about the impurities such as soil and small stones, after crushing, put it in a special barrel for fumigation, improve the oil yield, wrap it into a cake, put it in the press, and then it is the process of pressing.

Traditional oil mills are all labor-intensive, very hard, and stuffy.

When Liu Paner was looking through the information, she saw that there was a method of hydraulic oil extraction, and there were complete drawings. Even Liu Paner, a liberal arts student, can understand it.

With hydraulic oil extraction, then hydraulic grinding is naturally easy.

However, now there is a grain shop of the Wu family in the town, and Liu Paner will not build a water-powered mill for the time being. First of all, build an oil mill, so that people can have oil to eat, so that the pigs at home can have cake to eat, and there is enough fertilizer.

Liu Paner's family now has 30 pigs, and it is not enough to eat pigweed every day, but also to go to the Wu family's grain store to buy bran and soybean meal.

Although rapeseed cake is a little toxic in it, after fermentation, you can add a certain amount of rapeseed cake foil to feed pigs, chickens and ducks.

In addition, Liu Paner wants rapeseed cake meal, which also has a very important role, that is, to make organic fertilizer.

Because cake contains a lot of phosphorus, it is an essential fertilizer for farming. There are other nutrients that can be used to nourish the land well.

In short, the benefits are numerous.

Liu Paner drew the drawings and dimensions and went to Carpenter Li.

Carpenter Li was embarrassed, "Yuanqing's family, it's not that I don't want to help, but I don't know how to measure the strength of this thing, and the things I make may not be usable, nor may they be durable." My craft, you know, will make some tables, chairs, benches, and some simple things. ”

Liu Paner originally thought that if there were drawings, Carpenter Li would be able to make them, but now it seems that it is not possible, "It is difficult for me to be strong." Then I'll go to the county seat and find someone to help. ”

Carpenter Li smiled, "I can't help you, I can't help it." By the way, Yuanqing's family, you're using this to extract oil, right? ”

Liu Pan'er nodded, "Yes, hydraulic milling, oil extraction." If it can be done, it will be convenient for our village to eat oil. ”

Carpenter Li nodded and smiled, "That's really good, stir-fry without oil, it's not delicious." Those who work hard like us don't eat oil and don't have the strength. ”

"That's what Uncle Carpenter said." Liu Paner said with a smile, "I'll go to the county seat to find someone to help, and I won't disturb my uncle's work." ”

Carpenter Li nodded and watched Liu Pan'er leave.

Carpenter Li's daughter-in-law complained a little, feeling that it was inappropriate for her husband to refuse, "You said that you, who have studied carpenter for so many years and done carpenter work for so many years, why can't you make things from the Yuanqing family?" Even if you don't succeed once, you can do it a second time. Anyway, the labor and materials are all from the Yuanqing family, and we don't need to spend more money. ”

When Carpenter Li heard his wife's complaint, he didn't approve of it, and shook his head, "If I can do it, I'll do it; I can't do it, so I just say I can't do it. After all, this thing looks simple, but it is very complicated to do. It doesn't matter if I delay a little effort, if I delay the affairs of the Yuan Qing family, I am even more uneasy. ”

Carpenter Li's daughter-in-law disagreed, and was still complaining about Carpenter Li, "What's uneasy?" Once raw and twice cooked, it can always be made. Maybe you can make this hydraulic oil extraction tool, and you can still get praise from the county master. Anyway, it's not our family's money, you just need to spend some time. ”
