The Tang Dynasty started from saving Empress Changsun

Chapter 164

After breakfast, Chen Jingke took the initiative to find Zhang Ping, and the two came to his small courtyard together.

Take out the rice seeds soaked yesterday and plant them in three pots.

After finishing her work, she reminded: "Take out the pot to bask in the sun when it's hot at noon, and put it inside the house at other times. If the weather turns cold and it rains for days, you have to light the brazier in the house..."

She paused at this point, and said: "Your room has a fire wall and a heated kang, so it is more convenient to keep warm."

Chen Jingke nodded and said, "I see."

Zhang Ping took out a few pages of paper from his sleeve and said, "Here are some essentials for growing rice that I wrote. You can take a look and hope it will help you."

Chen Jingke said gratefully: "Thank you, if these rice seeds are successfully cultivated, I will definitely write your name on them."

Zhang Ping stared at him with big eyes, seeing that he didn't seem to be lying, his heart warmed up, but he shook his head and said, "I didn't do anything, so I dare not take credit for it."

Chen Jingke said domineeringly: "Why didn't you do it? If it weren't for your rice seeds, I don't know if you can grow them. Don't refuse, it's such a happy decision."

Zhang Ping glanced at him again, then lowered his head, not knowing what he was thinking, and did not refute.

Then the two came to the garden in the courtyard, trimmed the field she had selected, and even watered it themselves.

Yi Nu and Yuzhu naturally came to help, but they knew nothing about farming, so they could only help with some physical work.

"The grass must be removed to prevent it from competing with the seedlings for fertilizer. White ground is the best time for weeding. Where there is no crops, there is grass and deep plowing is enough to dig out the roots."

Zhang Ping explained to them: "You can also fertilize in advance. Ordinary fertilizers are easy to burn the crops to death. Just let them rot in the ground for a few days."

Yuzhu asked curiously: "Why did the fertilizer burn the crops to death when it wasn't hot? Why didn't they burn to death after they rotted?"

Zhang Ping shook his head and said, "I don't know, but this is the experience passed down from generation to generation. I tried it and it is true."

At this time, Chen Jingke explained: "Most objects contain heat, but usually this heat is hidden, or our eyes cannot see it."

"This kind of heat can be released through some special methods. For example, if the food is covered for too long, it will heat up, mold and rot, which is the result of the release of heat contained in the food."

"Fertilizer also contains heat. If you apply fertilizer directly to crops, it will be burned to death. After the fertilizer decomposes, the heat is released, and the rest is fertilizer, which is harmless to crops."

Zhang Ping froze for a moment, then showed a thoughtful expression.

Yi Nu and Yu Zhu both looked at a loss, but it was because they didn't understand them that they felt more profound, and said admiringly: "So that's how it is, real people know so much."

Naturally, Chen Jingke could see that they didn't understand, but this kind of thing really couldn't be explained clearly in a few words, so he didn't explain too much.

He just said: "You just need to know that the excess heat in the fertilizer can be released through decay. Putting the fertilizer in the ground decays too slowly, and the method of retting was invented in the Qin and Han Dynasties to speed it up."

"It is to dig a hole in the ground to put the compost pile in, and then cover it with a layer of soil to keep it warm, so that the compost will decay faster."

"The high temperature generated by retting can also kill insect eggs in the fertilizer, so as not to cause them to damage crops and reduce yields. The resulting juice is an insecticide, which can kill pests when sprayed on crops."

The ancients discovered the existence of fertilizer long ago. The earliest slash-and-burn farming discovered that plant ash could fertilize the field, so they took the initiative to use dead branches and leaves to burn ashes as fertilizer.

From the Spring and Autumn Period to the Qin and Han Dynasties, the retting and composting methods were summed up, which not only solved the problem of burning the roots of farmyard manure, but also made use of waste, so farmyard manure began to be widely used.

After the Wei and Jin Dynasties, it was discovered that some plants can also fertilize the fields, among which beans are the main ones.Sowing beans can not only harvest grain, but also can fertilize the field with straw, killing two birds with one stone.

Of course, these things are too unfamiliar to Yi Nu and Yu Zhu, and they are all taken as stories.

Zhang Ping was different. She had read agricultural books and knew about slash-and-burn farming, manure composting, planting beans to fertilize fields, etc., but she didn't know the development process.

I don’t know why retting does not burn the roots, and I don’t know that retting juice can kill insects, and I don’t know that the reason for planting beans to fertilize the field is because rhizobium bacteria fix nitrogen.

Listening to Chen Jingke's explanation can be said to be enlightening, and all the questions that I couldn't figure out before were answered one by one.

At the same time, she also felt his great knowledge (zhì) again, not only his poems are well written, but also his research on agriculture is so deep.

These things are very common in previous lives, just pay attention to the fact that it is everywhere on the Internet.

There are also many experts who organize ancient agricultural books into a line and connect them in series, so that people can better understand the development process of agriculture.

However, in this era, books are precious, and knowledge is even more precious.It is a very remarkable thing to be able to sort out these things and string them together.

So after listening to it, Zhang Ping stared at him with a pair of beautiful eyes and said, "It's unbelievable that a real person has such deep research in agriculture. The little girl did not know how much she made a fool of herself before, so I hope the real person is not to blame."

Chen Jingke was a little embarrassed by her, and said modestly: "Miss Zhang, don't say that, I just read a few books to understand some theoretical knowledge, and any old farmer is better than me when it comes to farming."

"What surprised me was you. I really didn't expect that in your capacity, you would know how to farm and would be willing to work in the fields yourself."

Zhang Ping seemed to have found a confidant, and said with an open heart: "My old man likes farming, and there are many agricultural books at home. When I was young, I was curious about how delicious food grows in the fields, so I often went to him."

"The Er Weng devoted himself to serving Tianzun and never married. He treated me as if he was his own. He taught me to read and write and also taught me to farm. But..."

Speaking of this, she was a little depressed, and said: "But other people don't understand him, and think that farming is degrading, so I am not allowed to farm with him."

Chen Jingke sighed and said: "The way of the world is like this. People who say they emphasize agriculture on their lips actually regard farmers as humble people in their hearts... What happened next?"

Zhang Ping seemed to have thought of something funny, a smile appeared on the corner of his mouth, and he said, "Er Weng doesn't listen to them, every time he scolds them for picking up the bowl to eat and putting down the bowl, he's not a good person."

"He not only took me to farm, but also took me into the water to catch fish and shrimp, and went to the market to play."

It can be seen that she likes the second grandfather very much. Speaking of the joyful smile on his face, Chen Jingke is also sincerely happy for her.

"You have a good Aon."

"Well, yes." Zhang Ping nodded heavily.

However, in today's world, is this really good?

She couldn't help recalling what Er Weng had told her: A girl must marry after all, and her husband's family would never allow her to do such things.

So she must learn how to be a lady and how to care for her husband and children while playing.Otherwise, how happy she is now will be how uncomfortable she will be in the future.

At that time, she naively asked, why can't she find a husband who also likes farming?
Er Weng told her that because of etiquette and face, she could not marry a farmer, and wealthy families would not allow their housewives to plow the fields.

Living in a wealthy family since she was a child, she naturally understands this truth.So I didn't forget to read books and learn etiquette, and strive to make myself a person who meets the expectations of the public.

But now... She took a look at Chen Jingke, and thought to herself: Er Weng, there may really be men in the world who don't care about my farming.
