But this pattern only lasted for a little more than a day, and Hong Tao got out of the house, rode a horse with a few dogs, and headed south. Gorou and Rokuro sent news that the land of Qionglin Yuan was about to start spring ploughing, and asked the officials if they had any other instructions.

"How did I forget this! Hurry up, prepare the barrel, and go to the water tiger wings to collect urine. And the crown said, as long as the urine does not, a bucket of urine gives a liter of wine! ”

A must have! When Hong Tao heard the word spring ploughing, he threw the pen and ran out. Then Zhu Bajin was unlucky, and he received a job with a heavier taste.

"You two go to the pharmacy to buy fifty catties of gypsum, and by the way, inquire where the plaster in the pharmacy came from, and I need the kind of white stone that burns the plaster."

Gorou Rokuro didn't run away either, their mission didn't taste heavy, but it was quite troublesome. There won't be so much plaster in the pharmacy, so you have to go door-to-door to make up a little bit.

"Big head, go and buy ten big iron pots for the officials, the bigger the better!"

"Hu Er, put aside the work in your hand first, and find someone to build a five-eye stove in the wind. Now, stay away from here! Immediately afterwards, Wang Dalang and Hu Er also received orders, and for a while, the construction site of Wujin Xing was full of chickens and dogs, and no one knew what kind of wind the horses were pumping again.

"Official, why do you want to collect those pickles?" The princess still felt sorry for her husband, and was afraid that Lian'er would not be able to do it alone, so she added an extra green lotus. These two little girls have to serve Hong Tao's eating, drinking, and sleeping every day, and also have to act as secretaries and translators.

“…… Remember! 50 catties of human urine are heated to 20%, steamed in a crockpot until 10, and 2 catties of cooked gypsum are stirred, dried and crushed. This material is called urea gypsum, 10 kg of base fertilizer per mu, 5 kg of top dressing in the later stage, and the effect is to be determined......"

Hong Tao did not answer Lian'er's question, but stretched out an index finger to the sky. Seeing this, Lian'er immediately took out a pen and paper from her briefcase, and Lu Lotus did not lag behind, so she quickly took the leather bag and held it up as a desk, and asked Lian'er to write it, recording every word the official said.

As for what they remembered, most of them didn't understand, but it didn't matter, the princess had already explained, the horse is now a big man who can write books and speak, every word is very precious, and it is not normal to be able to understand it! The laity don't need to understand, they just worship.

"Enlighten the big officials, human and animal feces and urine should be put into the soil pit to remove the cold and heat, and only after the sex is calm can the crops be watered." But the green lotus came for a short time, and it was impossible to worship blindly, and when he heard that the master was talking about the problem of cultivation and fertilization, he couldn't help but correct his mistakes.

"Oh, you know how to farm, too?" Lian'er couldn't hear anyone slandering her master, and she couldn't question it, so she was about to teach a lesson, but was stopped by Hong Tao.

"There is farmland in the palace, and the Queen Mother often has to go down to the fields to cultivate herself, so we naturally have to be familiar with the techniques......"

Midori doesn't feel like she's wrong, because she's well-founded. There was an imperial field in the palace, and although not every emperor liked to farm the land himself, the queen mother did not abandon this homework.

"Well, it's very good, the people live on food, and they can't starve to death if they can farm. But this fertilizer is different from the fertilizer you use, it's called chemical fertilizer. Just like the official's black gold line, in the hands of others it is a smoky and choking charcoal, but in the hands of the officials, it is smokeless and tasteless honeycomb charcoal. Do you want to learn how to make fertilizer from officials? If you want to learn, you must not be afraid of smelling bad, let alone afraid of soiling your dress. ”

Green Lotus is not right, whether it is human manure or human urine, if you want to use it as farm fertilizer, it is best to ferment and rot first, in order to be called fertilizer, the nutrients in it are easier to be absorbed by crops, and it will not burn roots. But this is not a farm fertilizer in the traditional sense, it should be called soil fertilizer, which is a kind of nitrogen fertilizer.

I didn't deliberately learn this thing from anyone, but because I liked to grow grapes in later generations and didn't want to buy chemical fertilizers, I went around collecting all kinds of home remedies and doing it myself, the picture was pure green and pollution-free, and then I talked about high yields.

Does soil fertilizer really work? It really works, this kind of soil method is not someone who has a hot brain, but in order to solve the problem of chemical fertilizer shortage in the early days of the founding of the People's Republic of China, many agricultural experts came up with an alternative method according to local conditions. Although it is not as effective as pure chemical fertilizer produced in industry, it is also faster than the simple use of farm fertilizer.

Isn't it bad to use farmyard manure? In the long run, the use of farm manure coupled with reasonable rotation tillage is indeed of great benefit to the land.

However, if you want to increase production in the short term, it is impossible to rely on farm fertilizer alone, and you must use chemical fertilizer. And it is not a chemical fertilizer that can be done, it is necessary to use several combinations to ensure that nitrogen, phosphorus, potassium and various trace elements are sufficient.

Well, it's a big drawback. Long-term use of chemical fertilizers and pesticides will gradually become acidic or alkaline, and become less and less suitable for farming. But Hong Tao can't take care of these anymore, he is only looking at the output at present, and he will talk about the protection of the land later.

"I'm not afraid, I want to learn!" Green Lotus is a girl who likes cleanliness very much, and it is not too much to describe it as spotless. Compared with her, Lian'er, who was originally very neat, looked very sloppy.

At this time, the contrast of suddenly letting such a girl learn how to boil urine is a bit big, and she was hesitating, but another female voice came from behind her.

It's not Lian'er, it's the smaller little little Dian Chenniang. This little guy will follow Hong Tao as long as he has the opportunity, and he has to follow if he doesn't have the opportunity to create opportunities.

In view of this situation, Hong Tao can also take her with him as much as possible, anyway, she won't cause any trouble to adults, why not make her happier.

"I'm not afraid, I'm learning!" With a leading Lian'er, she is not to be outdone, even if she really doesn't want to smell the smell, she has to be on top of it, and she can't be compared to Chen Niang.

"Can the slave family change a dress......" Lu He is not only a neat girl, but also likes to dress up very much, and makes the dress as beautiful as possible every day. Thinking about the smelly environment, she really couldn't bear this dress.

"Don't be afraid, you're still young, you don't really have to do your own work, just look at it with your eyes and remember it with your heart. Remember what the official said, art is not pressing. It doesn't matter if it's useful or not, as long as you can learn, try to learn it, maybe you will use it one day, and maybe one day you will save your life. Now the two of you take Chen Niang to Pig Killing Alley, buy 500 catties of pig and sheep bones from the butcher and hire a car to pull them back, and then see how the officials cast spells! ”

Hong Tao himself also likes to be clean, as long as the conditions allow, regardless of spring, summer, autumn and winter, he has to take a bath every day. Although I don't pay much attention to dressing up, my clothes must be clean, so I can naturally understand Midorihe's concerns. He didn't plan to let the three little girls do any work, but just wanted them to experience the difficulty of labor, and by the way, increase their knowledge.

A large five-mouth iron pot, the fire below is blazing, and the top is steaming. If there is rice porridge in the pot, the aroma will spread to the entire lake. It's a pity that there is human urine inside, and the smell is also wafting, even if you are in the limelight, you still have to cover your nose.

On the other side, there were five large iron pots, which were full of gypsum powder with white flowers, and several strong laborers covered their mouths and noses with strips of cloth and took turns to stir them.

Originally, raw gypsum had to be heated in a calciner to become cooked gypsum, but now it is too late to get a cast iron furnace body, so simply fry it in an iron pot. It's not good to fry it, it's not bad, it can be used if it's improvised, but it takes a long time and costs coal.

However, Wujin Xing is really not afraid of coal, with the stone mill and water mill in place, Zhu Bajin's group of apprentices have begun trial production, and small batches of honeycomb carbon are constantly being pressed and formed by hand, and neatly stacked under the greenhouse to dry.

Hong Tao was reluctant to use honeycomb charcoal, but changed to a simpler briquette. Anyway, I'm not afraid of smoke in the wild, how cheap and how to greet.

The pig and sheep bones that Lian'er and the others bought are also in place, but they can't be processed yet. These bones should also be heated in a large iron pot first, the fat is boiled out as much as possible, dried and then smashed with water, ground into powder with water, and mixed with plant ash is a good phosphorus and potassium fertilizer.

When the crown heard of this, he immediately sent troops to pull all the bones away. He wants to boil bone broth for the soldiers to drink, which is more or less oil star, and it can't be wasted. Hong Tao is not against the use of waste, but emphasized one point, no salt is allowed, otherwise let Shui Huyi compensate for his losses!

With farmhouse fertilizer, plus nitrogen fertilizer and phosphorus and potassium fertilizer, no matter how bad the rice sac flower is, Hong Tao will have no rut. The planting industry has always relied on God's grace, and even if there is a greenhouse, it is not much better. As soon as the flowers bloom, there will be a hailstorm, and the greenhouse is also in vain, so do your best to obey the destiny of God.
