In the fourth month of the lunar calendar, after two spring rains, the spring is even stronger. The swallows who flew to the south to spend the winter earlier also flew back.

There were no pesticides and fertilizers in this era. There were bugs in the field. In addition to relying on manpower to catch them, we also rely on animals such as swallows and frogs. Xipo Village has many dry land, frogs are relatively rare and swallows are common.

The villagers hope that the swallows would like their place, and they could come back every year instead of going to other places. So they treated the swallows very friendly, and they were almost worshipped.

If a naughty child dares to poke the swallow's mud nest with a wooden stick, broom, etc., a beating is absolutely inevitable. Don't blame his parents for being cruel. Swallows are really too important to farmers. If they annoy them, these naughty children will probably not even be able to eat in the future. What is the point of being beaten?

In fact, swallows are also nostalgic. Last year, most of them still go there. Last year, the swallows grew up and came back with their parents this year to form new families to build new nests.

There was a pair of swallows who chose to build nests in the Luo family's yard. Luo Yong and they were all very happy. The two small ones in the family squatted under the eaves all day long, watching the two swallows come back with soil bit by bit, building a swallow's nest bit by bit.

The weather became warmer, and Liulang and Qi Niang were also alive recently. They chased the chicks in the yard for no reason. When they were happy, they made a giggle and laugh, and the chicks were also chasing and chirping.

Although the brother and sister are twins, they don’t look very similar, after all, they are still fables.

The little girl Qi Niang looked smart, but Liu Lang looked more gentle and delicate than Qi Niang. The two were as old as they were, and they often had to fight. Every time they fought, Liu Lang was often the one who cried. There was no way, and he couldn't beat him.

Luo Yong came out of the house and brought the donkey into the car. When the two little ones below saw him, they hurriedly surrounded him: "Brother, where are you going?"

These two little Douding also said that they were four years old during the Chinese New Year. In fact, they were less than three years old. They could say something, but they were muttering and sometimes they didn't know much. In the past, when Luo Sanlang had not had any accidents, they didn't remember much. Later, Luo Yong woke up and they also recognized their babies. They just fed them delicious food and drink for the past few months, and they had already been fed them.

"Brother, go to the field to water the fertilizer, you two stay in the yard obediently." Luo Yong picked up a few wooden barrels from under the wall and placed them on the donkey cart, and took another long-handled water scoop.

"Brother, I want to go and water the fat too." Liulang said angrily.

"I also want to water the fat, I also want to water the fat." Qi Niang shouted.

"Goro, Goro." Luo Yong stood in the yard and shouted.

"What are you doing?" Goro poked a small head out of the convenience store.

"You take Liulang Qiniang to play for a while, don't let them run around." Luo Yong had no choice but to use these two little ones, so he called Wulang to come and help.

"They don't know how to play by themselves." Goro hummed: "I still have to work."

"Take them to play well, and when they grow up in the future, they can help you." Luo Yong coaxed him.

"How long will it take to wait?" Goro was worried.

"It's only been two or three years old. Look at how many children aged six or seven in the village can work," Luo Yong said.

"Okay." Goro thought for a while and felt that this investment could still be made.

"Brother, I want to take them too and let them work for me." Si Niang heard the sound of the wind and whispered her loose cloth shoes and came out.

"Okay, Liulang will take it to Silang, and Qiniang will bring it to you." Luo Yong assigned them.

Then Siniang and Wulang happily took Liulang and Qiniang to the convenience store to teach them how to work. At this moment, they were picking beans and picking out the bad beans in time so that the good beans would also worm them.

Luo Yong was relieved when he saw this scene. Seeing that in the room next to him, Er Niang was leaning forward to look here, so he waved his hand and signaled her to go there.

There are too many children in the family, especially a baby as big as Liulang Qiniang, which is definitely not OK if no one looks at him. Luo Yong and Er Niang have their own things to be busy with, so they had to coax Si Niang and the others to take these two young ones.

Luo Yong drove the donkey cart out of the yard, went down the small slope in front of his house, and first went to the ditch behind the pigpen to scoop some pig urine.

When his apprentices were building a pigpen for him, they considered that the terrain behind the pigpen was shorter and that pig urine and pig manure flowed there all year round. If they used adobe to repair the wall, they would not be soaked for a long time. So they found some stones and built a low wall with stones there, and then built adobe to build a brick.

A lot of fertilizer has been accumulated in the ditch behind the pigpen recently. When those things first came out, they tasted very strong and didn't look very good. They just fermented for a while, and the temperature has begun to rise recently. Gradually, the dirty water in the ditch turned dark green and the taste was not that heavy.

Luo used about one-fifth of the fat water in each wooden barrel, and then drove the donkey to his own field. When passing a ditch, he added some clean water from the ditch to the bucket. After blending it like this, the fat water will not be easy to burn seedlings.

The wheat in his wheat fields is growing taller now, and the millet has sprouted.

Working with crops is not a light work. Some fine farmers want to work hard in the fields every day. Luo Yong is only about ten acres of land. Generally, a normal household has 100 acres of land, and some people also have to open some wasteland to plant.

Luo Yong has spent some time on farming recently. He saw that the people here are still quite backward in planting technology. Although they also apply fertilization and watering, the fertilizers are mainly human, animal, and birds. There is a saying that compost, but they don’t know how to ferment.

The soil in the Luo family is not fertile. Luo used the book "Soil Fertilizer" in the space in the past two days and read it. This book mainly focuses on the soil structural properties and analysis of various elements, but also talks about some content about organic fertilizer.

Luo Yong saw a passage about green manure earlier, and wanted to try it, but when he thought about it, those things were buried in the fields and rotten, he was afraid that they would attract pests. There are no pesticides that can control pests these days.

As for compost, he is also doing it now. The straw that was pulled out from the pigpen is piled on a small piece of sand and gravel behind the pigpen. When the weather gets hotter and basks in the sun, it will probably be almost done. If you want to do it more carefully, you have to dig a hole and ferment it. Luo Yong has not yet made any effort to do this.

Last night, Luo Yong saw a note in that book. It should be a class note made by the owner of the book before, which read: "The method of burning soil dung, "Chen Funong Book", using hay and fine soil..."

Using this method to make fertilizer can not only obtain effective fertilizer in a relatively short time, but also kill bacterial eggs, which inhibits diseases and pests to a certain extent. Luo Yong thinks he should be able to try it.

I transported several trucks of fertile water to irrigate the land, but I couldn't water all the wheat from the five acres. I only watered more than one acre. Luo Yong made a mark there and would follow this mark to water it back tomorrow. In three or five days, I could water all the wheat.

When I went back, I passed by the pigpen and watered the vegetable field I opened there. The vegetables were watered quickly. When it didn’t rain, I had to water them almost every day. When the weather got hot, I would probably have to water them twice a day. Fortunately, I am close to home here, and the vegetable field is not big, so it is not very difficult to water.

Two days later, in the evening, Luo Yong wrote on the notes and burned dirt on a deserted slope outside his yard.

Many villagers saw the thick smoke soaring into the sky, thinking that it was the Luo family or the Yao family who had gone through water. Someone who was enthusiastic, rushed out of their homes with a wooden barrel, fed water from the ditch on the side of the road, and ran all the way to the entrance of the village. They came over and saw that there was no water flowing. They saw Luo Sanlang and Yao Weng standing next to a smokey mound talking, both of them were looking alright.

"Sanlang, what's going on?" As they came, these people were not in a hurry to go back. In the evening, it was the most leisurely time for the villagers to do this day.

"I plan to cook some fertilizer for the millet in the field." Luo Yong laughed when he saw that many of them were carrying buckets.

"What kind of fertilizer should be used to burn, but it should be used to burn ashes?" They also have the habit of using grass and ash to fertilize the fields. They just look at the small smoke-filled mound, and it doesn't seem like they want to burn ashes.

"There are hay and leaves added there. I guess the crops in the fields will like these. When they are ready tomorrow, they will also mix some pig urine in." Luo Sanlang pointed to the pile of things and squinted at everyone and said with a smile.

"What strange method is this? Don't mess up the crops in the fields." The villagers kindly reminded.

"Look, as long as you feed the pigs some cooked food, they will grow so fat. If you make some cooked food for the crops in the field, they might also like it." Luo Yong said this slightly innocent thing based on his current age.

When the villagers heard him say this, it seemed to make some sense. When Luo Sanlang and the others cooked hot food for the piglets, everyone thought it was a bit weird and some were unacceptable.

But they can see the development of things later. Over the past period of time, the pigs of the Luo family have been rich every day, and their round and plump appearance are no match for other people's pigs. So now people in the village say that Luo Sanlang is really smart and can think of anything that others can't think of.

This time, Luo Yong said that he wanted to cook food for the crops in the field, which was more absurd than the previous pig food. However, with the previous incident, no one interrupted the scene this time. He just watched the novelty and planned to pay attention to the movements of the Luo family in the next few days. If the fertilizers burned are really good, they naturally have to learn.

When they came to see each other the next evening, Luo poured pig urine on the burned dirt manure. The soil dried by the fire absorbed enough moisture. It looked a bit tide and dark, and it looked very fertile.

The farmer did not bother me. He reached out and grabbed it, and it was soft and pinched it, and it would not form a ball. An old farmer with decades of planting experience immediately said, "It's really a good fertilizer."

When the other villagers heard this, they immediately became bustling. It turned out that using hay and fine mud could also burn fertilizer. In this way, how much manure could they save?

In this era, the land was vast and sparsely populated. Because the equal-field system was implemented in the early years, every farmer planted many fields at home. So many fields needed to be fertilized, and the little human, animal manure and urine produced by his family was not enough. If Luo Sanlang's method was practical, they would almost no longer have to worry about the problem of insufficient fertilizer in the future. This is a great thing for the farmers and the farmers.

"If you just burned things, please leave them for two days first to remove the fire, so as not to damage the crops." The old farmer just now reminded Luo Yong again.

"Thank you for your reminder." Luo Yong also acted very modestly.

Afterwards, the villagers asked Luo Sanlang for advice, and the dirt was burned out with something, how to pile up these things and how to burn them. Luo Yong did not hide his own private interests, and said everything he knew.

Then the villagers began to collect things like hay, withered leaves and fine mud. That night, someone lit a pile of dirt dung near their homes. Thick smoke drizzled in the dark sky, drifting further and further under the dark sky until they disappeared between the mountains, making the sunset in the sky seem to smell a little fireworks.

Because many villagers in Xipo Village do tofu trading and have close contacts with people from several nearby villages, this method of burning dirt and dung quickly spread.

"I really don't know who thought of such a good method." One day, a villager was filled with dirt dung, holding a handful of dark and soft dirt dung burned from his home in his hand, sighing to his neighbor.

"You don't know?" his neighbor said: "This method of burning dirt is transmitted from Luo Sanlang in Xipo Village."

"Luo Sanlang?" The villagers felt that these three words sounded a little familiar.

"Maybe that the Luo coffin board?" His wife asked carefully.

"Yes, it's him." The neighbor nodded first, and then immediately said: "Bah, what coffin board? Don't talk nonsense like this again in the future. Be careful to tarnish Mr. Luo's reputation."

"Yes..." the couple quickly agreed.

At the same time, the same conversation has occurred in many other places.

...

"Who did you say?"

"Luo Yong."

"I haven't heard of this name before."

"It's the Luo coffin board."

"Oh! It's him!"

"Shh! Don't talk about any coffin board in the future."

...

...

"Where did you say this method come from?"

"The Luo family in Xipo Village."

"Luo Family?"

"It's that..."

"Oh, I remembered it, it's that Luo Coffin Board, right?"

"Oh, stop calling that."

...

...

"Luo Coffin Board..."

...

"Luo Coffin Board..."

...

"Luo Coffin Board..."
