"Boy, guess what I'll bring back to you?" The father mysteriously took out a cloth bag and said.

"I knew you couldn't guess it, look." Dad excitedly unbuttoned the cloth bag, "This is a picture." Yang Heng felt strange. Why did Dad bring some pictures to him?

"You don't know what pictures are, how did you learn secretly?" "Books, aren't books one by one?" Yang Heng was a little confused. This was indeed Yang Heng's mistake. The books of this era were scrolls, whether they were bamboo slips, silk books, or paper books, they were all scrolled up.

"What is a book? This is a book, but I exchanged it for a few preys. If you don't believe it, please read it." My father picked up a scroll of paper, untied the red rope tied on it, and slowly spread it out, "Look, aren't these all words? There are no paintings."

"Scroll six raising sheep felt and crispy cheese..." The manuscript, what is this? First, what is it? Yang Heng started to turn it up in these paper rolls. Oh, this is the first, and saw a capital letter written outside the paper roll, untied the tied rope and slowly unfolded.

"Qi people are important skills, and the preface of the historical records say that Qi people have no cover... Shennong is the plow and hoe..." This is actually the Qi people are important skills, a book of agriculture, but there is a place where Yang Heng didn't know many words on it, all of them are traditional Chinese.

"Grandma, where did you get the book? This book is amazing. It's a book that explains how to farm. Grandma, you are so good. You are also thinking about getting a book for your child." Yang Heng was a little excited, and for a moment he was a little incoherent.

"It's useful, but I'm afraid it's useless. This is what Grandpa went to a veteran's house to visit. He showed me what it was, saying that it was a spoil in a certain battle. At that time, he had not snatched anyone else. There was only such a bag of books left in that place. He had to take it back. He didn't know how to read, so he kept it there and almost burned it. I remembered that you like to listen to others' lectures, so I changed it back with a few preys. As long as you can use it, I'll be relieved, and I didn't waste some prey."

"It can be used, it can be used, thank you, grandpa, thank you grandpa." "What are you saying? You are my son, I am yours. You like to study. Isn't this what you should do if I change the book for you?" the father scolded.

It can be seen that Yang Heng's understanding of his father has further improved. Isn't his father so ruthless?

"Grandma, what else have you brought back? You won't bring back such a book." Yang Heng was very curious.

"Boy, are you thinking about what Grandpa brings you? Don't worry about what you have?" Dad turned around and walked out, then brought in a large cloth bag, "Grandpa, you're back with so much food." Yang Heng was surprised.

"How can it be? Bang, this is for you, madam, this is yours." Yang Heng got a small cloth bag, and my mother's one was a piece of cloth. "What is this, cake." Yang Heng said with some disappointment.

"This is Hu cake. You have eaten it before, and you said it is delicious. Why, you eat meat, but you don't like it anymore." "I like it, I like it, why don't you like it? It's just that I haven't eaten it for a long time." Yang Heng quickly explained. No matter whether it's delicious or not, this is my father's wish. "If you don't like it, you don't like it. Your grandfather bought this for the sake of getting it, right? You guy, you can't even lie. Don't you buy it for you often when you are in the city?" My mother smiled and scolded.

"Look, I also bought some growing grain. Whether the field is successful or not, I still have to buy this kind of seed." Then my father took out a few bags of seeds from the cloth bag.

"This is millet, this is millet, this is rice, and there are some bean seeds. They are said to be fat, but I don't know if they can be planted or not." My father is indeed not a farmer, and now he can't even buy seeds. The rice should be rice. Yang Heng seems to remember that there was no such thing as dry rice in this era. (Yang Heng was a little wrong at this time. There should be dry rice at this time, but not many were planted). Looking at the deserted ridge here, how can rice be grown? But what are millet and millet are? Yang Heng opened the cloth bag and observed it. Then he found that millet is yellow rice, and millet should be a crop like sorghum in later generations, but it is a bit different from sorghum.

The beans look like mung bean seeds, which is used to fatten the fields? When Yang Heng checked Qimin Yao, he realized that the mung beans were really used to fatten the fields. Qimin Yao wrote in the art, "In all the methods of beautiful fields, mung beans are the best, and small beans are the second,... It is the spring valley field, and ten stones are collected per mu, and the beauty is the same as silkworm arrows and ripe manure.

From this paragraph, we can see that these mung beans are used as fertilizer. Yang Heng also remembered that he had read some online articles in his previous life, and there was a saying that mung beans are used as fertilizer. It seems that the source is here.

Even Yang Heng had a saying of interplanting in rural areas in his previous life, that is, soybeans and corn can be interplanted. Corn can be used to increase yield by using rhizobia on soybeans. It seems that mung beans have the same effect. However, when mung beans are used here, they cannot harvest fruits. Instead, they will be turned into the fields after the bean seedlings grow and then plant grains in the next year. According to Qimin, the effect is good. It can actually reach ten stones per mu. I don’t know whether it is true or false. What can be tested is just to consume two or three liters of mung bean seeds. The fields don’t matter. In this era, due to the lack of fertilizer, they usually plant a year, and they have to take a year off and take turns to facilitate the rest of the fields.

Thinking of this, Yang Heng suddenly thought of something, that is, when reclaiming the fields, he packed a lot of weeds, even leaves and other debris in the fields. Originally, Yang Heng piled them all in a big pit to prepare fermentation, but if the fermentation is not good, the fields will easily grow insects and cause overgrowth of weeds. Yang Heng remembered that in his previous life, he wanted to use crop straws in the fields to make mechanical charcoal. He once checked about mechanical charcoal online, among which, grinding mechanical charcoal into powder can add some nutrients to the fields, and even improve the field's ability to absorb heat, increase crops, or vegetable production, and improve quality. Can these weeds, leaves, etc. be carbonized? This can not only be used as fertilizer, but also kill insect eggs and weed seeds inside?
