Today's meal, there is actually meat!

Stir-fried bacon with leeks.

The bacon was no more, no less, just cut into three slices, and the rest was all leeks.

One piece of Zhu Ming, one piece of Zhu Guoxiang, one piece of children, and three pieces of bacon are finished. There was no way to refuse, so Mrs. Yan grabbed the meat with her chopsticks and stuffed it into their bowls.

The corn porridge was also replaced with corn, and it still did not come off the shell, and the taste was a little poor, but it was dry anyway.

After breakfast, Mrs. Yan went out with a hoe, saying that she was going to weed the wheat. Her family has more than 20 acres of land, most of which is rented to villagers, but she also keeps one acre for her own cultivation.

Shen Yourong went to wash the dishes and brush the pots, then fed the chickens, and then swept the floor.

Several rooms were swept, and the yard was swept again.

When sweeping the yard, there was an unexpected harvest and two pieces of horse manure were found. Of course, horse manure has to be collected and used for compost to grow crops.

After cleaning the inside and outside of the house, Shen Yourong went to weed under the fence wall again, and brought dishwashing water to water the vegetables in the vegetable furrow.

As for the little kid, he is concentrating on practicing calligraphy.

Probably in order to save paper and ink, Bai Qi dipped a brush in water and squatted in the yard to write on the ground.

Don't be afraid of hurting the pen, this broken pen is self-made, and the one who wrote the "Three Character Classic" for Zhu Ming was bought.

"Hey, Dean Zhu, what are you looking at?" Zhu Ming stretched out his hand to block his father's sight.

Zhu Guoxiang's expression was a little embarrassed, and he retracted his gaze and said, "I'm looking at what kind of vegetables the people of the Song Dynasty planted." ”

Zhu Ming teased: "How do I think, you are looking at the person who pours the vegetables?" ”

"I'm not a pervert." Zhu Guoxiang beat him to death and did not admit it.

Zhu Ming smiled and said, "Peek at it, peek at it, what are you arguing about?" It is also normal for older bachelors to suddenly become younger, and there is a turmoil in their hearts. ”

"It's not what you think," Zhu Guoxiang hurriedly explained, "Do you think this Shen lady, doesn't it look like your mother was young?" ”

Zhu Ming said sarcastically: "In your old eyes, as long as you are a beautiful woman, it is like my mother when she was young, anyway, the final interpretation is up to you." ”

Zhu Guoxiang said hurriedly: "I'm not talking about looks, I'm talking about that kind of temperament." Do you understand temperament? ”

"Temperament is a mysterious, you can say whatever you want. I understand, no need to say it again, the explanation is a cover-up," Zhu Ming said with a smile, "People in their fifties, if you marry a pretty widow in your early twenties, do you think this should be called an old cow to gnaw tender grass?" Say yes, you're younger again. Say no, your mental age ......."

"Fuck off!" Zhu Guoxiang was annoyed and angry.

Zhu Ming took advantage of the victory to pursue: "I'm in a hurry, someone is in a hurry." I know who it is, but I won't say it. ”

"I'm too lazy to pay attention to you." Zhu Guoxiang walked away angrily.

The bickering won, and Zhu Ming was triumphant and whistled happily.

Zhu Guoxiang slowly walked behind Shen Yourong, looked at the rape field in the distance and asked, "In another month, these rapes will be ripe, what will be planted after harvesting rapeseed?" ”

Shen Yourong was still watering the vegetables, and he didn't raise his head, and replied, "Plant rice." ”

"Is Xixiang County all rape rice rotation?" Zhu Guoxiang asked.

Shen Yourong stood up and rubbed his waist: "I didn't know about planting in turns before, and I wasted my strength. I heard my father say that it was a method brought by the people of Shuzhong, and the transfer envoy ordered all states and counties to promote it. ”

Zhu Guoxiang asked again: "Shen Niangzi's family also grows rape and rice?" ”

"Orphans and widows, you can't plant that," Shen Yourong said, "When planting rape in the new season, plant less, if you plant one or two acres, it will be very troublesome to drain and turn over the land, and the slightest mistake will miss the agricultural time." This rape and rice are planted in rotation, and the family has to have strong labor to be busy. ”

"Rapeseed seedling transplanting is, where is it busy?" Zhu Guoxiang said.

Shen Yourong was puzzled: "I only know how to transplant seedlings, and this rape seedling can also be transplanted?" ”

"Yes." Zhu Guoxiang began to inquire carefully about the cultivation methods of the Northern Song Dynasty.

After a while, I asked and understood, and then I went back to discuss with my son.

Zhu Ming smiled shyly: "It's okay, Dean Zhu, they're all starting to hook up." ”

"Don't talk nonsense," Zhu Guoxiang said with a serious expression, "I don't know about the south, I just say that here in Hanzhong, the rice planting process has basically matured, but I don't know how to control water and drought and raise seedlings." Therefore, rice cultivation is more severely restricted by climatic and geographical conditions, and cannot reach the limit of rice production in ancient times. ”

Hearing that he was talking about business, Zhu Ming also put away his smile: "How much can the yield be increased by that method of controlling water and drought seedlings?" ”

Zhu Guoxiang explained carefully: "It's not good to count, it depends on the specific situation. The advantages of this method are to improve the quality of seedlings, reduce the cost of raising seedlings, and enhance the ability of disease prevention and resistance. ”

"Why can dry seedlings improve the quality of seedlings?" Zhu Ming was a little curious.

Zhu Guoxiang sorted out the wording and tried his best to make Zhu Ming understand: "Water control and drought breeding, seedlings grow in an arid environment, soil moisture affects the differentiation of seedling roots, controls the occurrence of some seedling roots, and thus increases the number of latent roots." At the same time, the cytoplasmic concentration of dry-bred seedlings increased, the nutrient accumulation was abundant, and the plants were always in a high-energy state. When dry-fed seedlings are transplanted to paddy fields, the root primordium that has been differentiated but not elongated will rapidly develop into new roots, forming the explosive power of roots......"

"Stop, stop, you don't have to say any more." Zhu Ming was really not interested in this thing.

The technology of controlling water and drought seedlings was introduced and promoted in the Ming Dynasty, which made the rice yield per mu in the Ming Dynasty quickly exceed that of the Song Dynasty!

Although Zhu Ming doesn't know how to farm, he knows how to make use of it: "If we guide technological innovation and help the people increase production and income, we can quickly gain the respect of the villagers and gain a firm foothold in Xixiang County." ”

Zhu Guoxiang continued: "In addition, farmers in Hanzhong have mastered the technology of rapeseed rice rotation. However, they do not know how to raise rapeseed seedlings and transplant them, so they have to rush to plant rapeseed when they change them, and they need to double their labor in the short term. If rapeseed seedling transplanting technology is used, it can not only reduce labor input, but also improve the quality of rapeseed seedlings, enhance the disease resistance of rapeseed, and increase the yield per mu of rapeseed. ”

Zhu Ming couldn't help asking: "Seedling transplanting is very simple, right?" ”

"It's very simple, but there is a trick," Zhu said, "and it can be combined with water-controlled and drought-raised seedling technology, because dry-raised seedlings can postpone transplanting, so that there is no need to rush for time when planting is rotated." ”

Water-upland rotation can improve the air and water permeability of paddy fields, improve soil fertility, and reduce the damage of diseases, pests and weeds.

The emergence of rapeseed rice rotation was a breakthrough in the agriculture of southern China in ancient China.

At present, the rapeseed rice rotation method only needs to raise seedlings in drought and transplant rape seedlings, which means that this method is completely mature.

Zhu Ming asked: "Is there any rice planted in Mrs. Shen's house?" ”

Zhu Guoxiang shook his head and said: "No, most of her family's land is rented out, and she only grows some wheat and millet on dry land." Serving the paddy fields requires strong labor, and it also involves plowing cattle and irrigation, and it is difficult for orphans and widows to deal with it. ”

Zhu Ming said: "You can't tell the farmers directly about your two new methods, they don't believe it. We need to make some achievements first, let the villagers know that we are agricultural masters, and then they will be obedient. When we taste the sweetness of increasing production and income, the farmers will be completely convinced, and they will become respectful of us. ”

"But Mrs. Shen doesn't grow rice and rape at home, so we have no place to demonstrate. It is impossible to take back the paddy fields rented out by the tenants, which is equivalent to smashing the tenants' jobs, which is not good for Shen Niangzi and our reputation. Zhu Guoxiang said with a headache.

Zhu Ming said: "We have sweet potatoes and corn seeds, which can be planted in the mountains, and they will definitely be famous when they are harvested." Do you have any other tricks? ”

Zhu Guoxiang looked at the mountains in the distance: "Collect wild shiitake mushrooms from the mountains and make their own mushrooms, and you can grow shiitake mushrooms artificially." By the way, I made a strain of Ganoderma lucidum, and I also planted Ganoderma lucidum with a large grinding plate! ”

Artificial mushroom cultivation technology also existed in ancient times, but it was not until Zhao Jiu established the Southern Song Dynasty. The inventor of the technology is called Wu San, who is respectfully called "Wu Sangong", and after his death, he also built a temple to worship, and the folk worship him as the "mushroom god".

Zhu Guoxiang pointed to the vegetable furrow under the fence wall and said with a smile: "See? Daylily. ”

"See, it's not blooming yet." Zhu Ming said.

Zhu Guoxiang said: "With daylily, colchicine can be extracted to induce polyploidy cultivation of plants. Vegetables, grains, including mushrooms, can be done in this way. ”

Zhu Ming asked: "Do you need high-end equipment to extract colchicine?" ”

Zhu Guoxiang said: "You have to get distilled liquor first, just above 50 degrees." The goldenrod is washed, soaked in alcohol, and extracted by reflux at high temperature, and the resulting supernatant is rich in colchicine. ”

"It's that simple?" Zhu Ming was surprised.

Zhu Guoxiang asked rhetorically: "How complicated do you think it can be?" ”

Shen Yourong took care of the vegetable furrow, went to the eaves of the kitchen, and chopped some of the firewood that he had picked up home before and moved it to the kitchen, and the rest were all stacked neatly against the wall.

At this point, the farm work is still not done.

Shen Yourong took out a clean linen cloth, wiped the mulberry leaves picked back in the morning, leaf by leaf, and brought them to the silkworm house to feed the silkworm babies.

After feeding the silkworms and collecting the silkworm feces and composting them, Shen Yourong finally came to the courtyard and said to Zhu Ming: "Dalang, I'm tired of explaining the "Three Character Classic". ”

Not only for children, but also for adults.

Because Bai Qi can't remember it when he is young, only if Shen Yourong remembers it, it will be convenient for him to tutor his son in the future.

It was noon, but there was no smoke in every house.

Zhu Ming sat down in the courtyard and asked, "If Shen Niangzi doesn't understand anything, you can point it out." ”

Shen Yourong actually knew many allusions such as Meng Mu, Dou Yanshan, Huang Xiang, Kong Rong, etc., and the first question he asked was: "It is said that the ecliptic, the sun is coming." Said the equator, the right in the middle. What does this mean? ”

Zhu Ming went to the pyre under the eaves, folded a dead branch, and drew a pattern on the ground: "This is the earth, this is the sun." Sunday is 365 degrees, and the sun moves 1 degree every day, connecting the position of the sun every day is a circle. This circle is called the 'ecliptic'. This is called 'the ecliptic, the sun is born'. ”

Then, Zhu Ming drew a large round ball: "This is the celestial sphere, which wraps the earth." The upper part is the celestial north pole, the lower part is the celestial south pole, and the north and south poles are connected in series as the axis, and a circle is drawn around this axis in the center of the celestial sphere, and the circle drawn is the 'equator'. This is called 'the equator, the middle power'. ”

It's kind of similar to the geocentric theory, the universe is a celestial sphere, the earth is in the center of the celestial sphere, and the sun rotates around the earth.

Zhu Ming couldn't explain more, and it was impossible for him to talk about modern astronomical knowledge.

After all, Shen Yourong couldn't even figure out the ecliptic and equator, so what was the use of saying more?

Looking at the pattern on the ground, Shen Yourong pondered carefully, digested it for a long time before he figured it out, and said with sincere admiration: "Da Lang is really knowledgeable!" ”

Bai Qi, a little brat, looked at the circle representing the earth and was stunned, and couldn't help asking, "Is the earth round?" ”

Without waiting for Zhu Ming to speak, Shen Yourong said: "The sky is round, and the earth is square. ”

Bai Qi asked again: "The earth is floating in the heavenly sphere, why doesn't it fall?" ”

Shen Yourong couldn't answer, looked at the pattern on the ground, and couldn't help but look up at Zhu Ming.

Zhu Guoxiang did not like to fool the character, he snatched the dead branch from his son's hand, and drew a model of the solar system on the ground: "The earth is round, not only round, but also a ball." This is the sun, which does not move in the middle, and the earth and the five stars of gold, wood, water, fire, and earth, revolve around the sun day and night. This is the moon, and the moon is also a ball that revolves around the earth. ”

Shen Yourong was dumbfounded when he heard it, but Bai Qi's eyes lit up, this little kid felt amazing.

Immediately afterwards, Zhu Guoxiang relied on the solar system model to explain why the moon is cloudy and sunny, and why the sun rises in the east and sets towards the west mountain.

Shen Yourong clenched his fists, treating his fists as the earth, and said dizzily: "We live on the ball, can there be people living under the ball?" ”

"Someone." Zhu Guoxiang said.

Shen Yourong was worried about the humans on the other side of the world: "What should I do if those people fall?" ”

"You can't fall, the earth has gravity." Zhu Guoxiang said.

"What is gravity?" Shen Yourong asked.

Listening to his father's continued explanation, Zhu Ming pursed his lips and walked to the fence wall to look at the scenery in the distance.

Just these 100,000 whys, don't want to talk about the "Three Character Classic" today, since my father is so idle, Zhu Ming is too lazy to go over and get involved.
