After plowing for about two hours, Zhao Junsheng felt that the cattle were a little tired. He stopped and asked someone to bring a basin of water and a bundle of grass. Physical and mental, the plowing speed is faster.

In one day, Zhao Junsheng cultivated four mu of land, one mu more than the yellow tree.

Back at Huang Shu's home in the evening, Huang Shu's old lady had already prepared a meal.

The accompanying officials and soldiers had their own place to eat, Zhao Junsheng ignored them, and Hua Mulan and their children ate with Huang's family.

Zhao Junsheng sat down at the table and saw a bowl of white flaky soup among several dishes on the table. There were some vegetable leaves in the soup. It looked like tofu, but it was different from the tofu of later generations.

"This is?"

Huang Lishi said: "This is tofu. Presumably the king and princess have never eaten this kind of food that ordinary people eat?"

It is said that tofu was invented by Liu An, king of Huainan in the Western Han Dynasty. Zhao Junsheng has never eaten tofu since he came to this world. After all, the tofu at this time is far inferior in terms of solidification and taste, so it has not become the mainstream of cooking.

Zhao Junsheng picked up a piece of bamboo chopsticks and put it in his mouth to eat. The taste was really bad. No wonder tofu can still become the mainstream of cooking at this time. He asked Mrs. Huang: "Old lady, your tofu is soaked in soybeans. Then grind it into soybean milk, then wrap the soybean milk in gauze, press a heavy object to make the soybean milk flow out, and then put salt in the soybean milk, is this the way?”

Mrs. Huang said in amazement: "That's exactly the case, but I don't think the king knows how to make tofu!"

Zhao Junsheng said with a smile: "Guess the old lady definitely didn't heat up the soy milk, but directly ordered bittern in the cold soy milk, is that right?"

Mrs. Huang asked puzzledly, "Isn't that the way tofu is made? Why do you need to heat it?"

Zhao Junsheng said: "You still have soy milk here, right? Why don't you heat the soy milk according to Gu's method, get rid of the suspended foam, and then try some bittern!"

Mrs. Huang stopped eating and walked to the kitchen full of doubts.

When Zhao Junsheng came to the kitchen to serve the meal, he saw Mrs. Huang had already ordered the brine, and hurried over to put down the bowls and chopsticks and said, "Old lady, come here, let Gu come!"

He took the spatula and kept stirring the soymilk in the wooden bucket. While stirring, the tofu flower condensed in the wooden bucket. He immediately said, "Hurry up and bring a big wooden basin!"

After about a quarter of an hour after the tofu flower had solidified, Zhao Junsheng spread a large piece of gauze on a large wooden basin, and called Huang Shu and Huang Li to pull up the four corners of the gauze.

Zhao Junsheng poured the tofu flowers in the barrel into the gauze, then asked Huang Shu and Huang Li to wrap the gauze around the tofu flowers, and asked his eldest son to find a door panel and lay it on the ground, and put the gauze bags wrapped in the tofu flowers On the door panel, a wooden pot lid is used to press the gauze bag, and the gauze bag containing the tofu flower is flattened, and the water in the gauze bag keeps overflowing.

After everyone finished eating, Mrs. Huang Li packed up the dishes and went back

When she went to the stove to wash the dishes, she screamed. Everyone thought she was in the kitchen, and they all ran to the kitchen. Only then did they find that Mrs. Huang was squatting by the door panel on the ground, staring at a tofu disc in a daze. White bái nèn is tender, exudes an attractive bean aroma, and is still steaming on top.

Zhao Junsheng took a kitchen knife and squatted down, cut a small piece and put it in a bowl for Hua Mulan: "Try it!"

Hua Mulan took the bowl, took the chopsticks and put it in her mouth, "Well, it's delicious, hǎo nèn!"

"Everyone, try it!" Zhao Junsheng cut a small piece for each member of Huang Shu's family to taste. After eating, everyone said that it was good. It was much more tender than Mrs. Huang's before. Much better too.

"Oh, it turns out that as long as the soy milk is heated and boiled, the taste will be completely different, and it will look better. It's really an eye-opener for old ladies!" Old lady Huang said in amazement.

At this time, Hua Mulan smiled and said: "Old lady, you are the only one who knows the skill of making tofu now. With this skill, you can open a tofu shop in the city to sell tofu, and keep your family's food and clothing for generations to come." Don't worry!"

The Huang family were all taken aback, looking at Mrs. Huang, but Mrs. Huang looked at Zhao Junsheng, hesitantly said: "But this... If the king hadn't suggested something, how would the old woman know that boiling soy milk can make tofu so tender? tasty?"

But Hua Mulan said: "Don't worry if you are always old, will the king still go to the street to open a tofu shop and compete with you for business?"

"Hey, my lord, what a gift!" Mrs. Huang yelled, and immediately pulled her sons, grandchildren, and daughter-in-law down to their knees, kowtowing their heads in thanks.

"Get up!"

Zhao Junsheng got everyone in the Huang family to get up, and said to them: "This soybean can not only be made into tofu, but also into dried tofu. When making tofu just now, you only need to put a heavy object on the lid of the pot to dry out the water. , this tofu becomes dried tofu! You can also use a special square-shaped mold to make tofu that is square and square, which is both delicious and beautiful. Tofu can be boiled in soup or fried. Neen, there are many ways to do it!"

Later, Mrs. Huang made dried tofu according to the method Zhao Junsheng said. Later, the Huang family really went to the city to open a tofu shop. Time-honored brand.

After dark, Zhao Junsheng saw Huang Shu and his son taking advantage of the moonlight to harvest the dry soybean stalks on the threshing floor, walked over and asked, "Old Huang, what do you do with these soybean stalks? Do you use them as firewood?" ?”

"Yeah, what can I do if I don't use it as firewood?" Huang Shu asked doubtfully.

Zhao Junsheng waved his hands and said, "No, no, it's too wasteful to use as firewood! Now, I will teach you how to make soybean stalks, dead leaves, cow dung, pig dung, and sheep dung into fertilizer!"

Huang Shu was even more puzzled: "Livestock manure itself is fertilizer, how can it be made into fertilizer?"

Zhao Junsheng said: "Livestock manure is indeed a fertilizer, and it can be directly fertilized in the field, but there are many young eggs of pests in the manure of livestock. If these larvae eggs are not treated and killed, when the spring is warm and the flowers bloom in the next year, the larvae eggs will be killed. It grows up and endangers the crops!"

Zhao Junsheng knows that treating manure in later generations is not just about killing insects in manure. Livestock manure contains a lot of antibiotics. Using high-temperature composting technology can not only kill larvae in manure, but the high temperature generated during the fermentation process can also destroy manure residues. The molecular structure of the drug.Of course, in this era, antibiotics are not widely used to treat livestock diseases, so naturally there will be no antibiotics in manure.

Huang Shu was stunned: "I said why there are always so many pests in the field every year. I dare say that there are larvae in the excrement of livestock!"

"No, the larvae of pests are not only found in livestock manure, but also in large quantities in the soil, and even the wind can blow pests, so these pests cannot be removed, but treating livestock manure can reduce the number and types of pests, understand right?"

"Understood, I would like to ask your majesty to give me the method of making fertilizer from livestock manure, soybean platycodon, and dead tree leaves!" Huang Shu said hastily.

Zhao Junsheng ordered: "Your father and son are outside the yard first.

Find an open space, a little closer to the water source, so it is convenient to fetch water, and a little farther away from the house, it will be very smelly.Use soil to build a square ridge on the open space. The size of the area surrounded by the square ridge depends on how much material you have!The soil ridge should be about one foot high to prevent running water! "

"Now insert a few long wooden sticks into the enclosed square soil ridge circle, and then spread a layer of straw and leaves about one foot or one and a half feet thick, sprinkle some urine, and then spread a layer of livestock manure, and then Spread a layer of straw and leaves, sprinkle urine, and then spread livestock manure, and so on. The straw and dead leaves must be wet with water before spreading, and the water can be squeezed out when you stretch out your hand. Remember to spread each layer Straws or leaves have to be drenched with human urine, horse urine, etc., as long as it is urine!"

"After piling up, cover the piled straw and manure with mud, just like you use mud to paste walls, understand?"

"In about ten days, you will see that the dung pile begins to sink, and the temperature in the pile will drop. At this time, you need to turn over the pile again, mix the badly rotten straw and dung on the edge with the middle, and seal the pile again. There are white hyphae, add some water and re-seal the pile!"

"The manure pile will definitely shrink. When the bellflower turns dark brown to dark brown, and the leached liquid is dark brown to light yellow, and it is brittle, it means that the manure has been decomposed, and it can be taken out to fertilize the field!"

After hearing this, Huang Shu was astonished, "Dare to use this method to make straw into fertilizer. According to what the king said, wouldn't wheat straw and other straws also be made into fertilizer?"

Zhao Junsheng nodded and said, "Of course it is also possible, but the straw needs to be fed to the livestock. As long as the straw is not eaten by the livestock, it can be made into fertilizer by this method!"

Chapter 667 Environmental Problems Brought by Ma Zheng

On the third day, while others continued to harvest soybeans, Zhao Junsheng and Huang Shu began to sow wheat seeds in the plowed fields.

In the area south of the Great Wall, almost all the wheat planted is winter wheat, while in the north of the Great Wall, mostly spring wheat is planted.

Before sowing, base fertilizer should be applied to the plowed field. Today's farmers don't have many ways to fertilize, nothing more than self-produced organic fertilizer. The field is full of stench all day long, and the yellow tree carries the dung bucket They fertilized in the front, Zhao Junsheng planted the seeds in the back, and the others stayed away because of the stench.

The way of sowing is to scatter the wheat seeds evenly in the field. This is also a technical job. How many catties of wheat seeds should be scatter per mu? , After the seedlings emerge, the field becomes lame. Some places have very dense wheat seedlings, while some places have no wheat seedlings or are sparse. This not only looks ugly, but also directly affects the yield.

After a tiring day, Zhao Junsheng and others walked back. When they passed a small ditch, Zhao Junsheng found that there was water in it and it was covered with grass. , he took a bamboo dustpan and put it in the ditch, and asked Xiao Huang to go to the other side of the ditch to wade over, and let him make noise when wading.

When Xiao Huang came over from the other side of the ditch, Zhao Junsheng immediately picked up the dustpan, and the dustpan came out of the water. Dozens of loaches were swimming in the dustpan, and there were several eels in the middle.

"Your Majesty wants to get loach and snake fish, what do you want to do?" Huang Shu asked while watching.

Zhao Junsheng poured a large amount of loach into the bucket and said, "Of course it's for eating, Xiao Huang, let's continue!"

Huang Shu and his son were very surprised: "These two things can be eaten? They are everywhere in the ditch!"

Zhao Junsheng turned around and asked in surprise, "Of course you can eat it. Have you never eaten it?"

Both Huang Shu and his son shook their heads: "This loach and snake fish are too embarrassing and scary to grow. None of us have eaten them. Even in the age of starvation, we would rather eat grass roots and bark than these things!"
