C309: doing experiments

"Little grandma, have some water." Double happiness was afraid that she was over worried, so she put the water in front of her.

Fill two, Chen nianran's line of vision or did not move in front of several kinds of land. This is a small piece of land, that is, ordinary black land that can grow agricultural products, and yellow land that doesn't grow much.

Not far away, an old farmer was still hoeing. From time to time, the old farmer glanced at the knife and looked like he was curious and didn't dare to ask.

Not far away is a mountain forest. Xiaoanzi and Xiwu are going hunting in the mountain. "Little grandma, I'll see if there's any harvest in washing five."

Just at this time, wash five to carry a head of prey to come out, double joy excitedly want to go.

"Go, go."

Chen nianran waves and looks back. It seems that Xiwu has hit a good prey. It seems that this guy has learned how to hunt in the mountains. The effect is different.

The old farmer on one side looked at the hunter in the distance enviously. Seeing Chen nianran coming to him, he stood there chattily. "Madame!"

"Father, how is the harvest this year? I think the effect of the bracts you serve seems to be good. "

Seeing Chen nianran's kindness, the old farmer also relaxed, "if I go back to my wife, the harvest this year is not good. I've worked hard to serve these little things. Now it looks good. But once it rains heavily, the mountain mudslides and so on slide down, the crops of this land don't know whether they can be saved. No plants can be planted anywhere else. "

The old farmer frowned as he spoke.

Chen nianran is interested to see the different distribution of these plants in front of him. "Uncle, you must have a lot of experience in farming. I thought for a moment, like this kind of corn, if planted in this kind of loess field, will there be a harvest? "

The old farmer smiled and wiped his sweat. "Madam, how dry do you look at this yellow mud field. You can't plant corn. If you want to plant corn, you have to look like this piece of black land under my feet. Alas, this one of us is Huangni gang Poverty is yellow mud land, so is suffering. If not, how could our place be sparsely populated? "

"That's it."

Chen nianran knows, but she also knows that there are some farmers living here. Most of all, they came here to evade taxes, or ancestors came to live in such a place to escape.

There are not many farmers with a fixed population here. In recent years, any family with a little bit of Li Gang's interest will all hang out well, so they will move away.

There are not many important people, but there are a group of old people and children.

At this moment, Chen nianran's heart is also a little frustrated.

But she doesn't believe that it can't be changed. At this time, she stared at the land in front of her and thought about how to change it.

This is a place where yellow and black mud are mixed. Most of the black mud that can be cultivated has been developed. What is left can not be reclaimed, that is, some yellow mud land.

However, this kind of yellow mud land occupies a lot of places.

"eh, it seems that the yellow and black areas can also be planted?" Look at the middle area, where the yellow and black mud are mixed. There is a strong bract growing there.

"Old man, it seems that this kind of place with yellow and black mud can grow, too?"

The old farmer glanced casually, "yes, you can grow plants just as you like. However, it's just a matter of reluctance. "

Chen nianran laughed, "ha ha Ha ha... "

The old farmer suddenly laughed at her, his eyes were wide with fear. Back away, the hoe in my hand is even tighter. This woman, there is no one with a brain disorder. Alas, it's a pity to see that it's thin skinned and tender. How could it be a deranged person.

Shuangxi also ran from a distance, "little grandma, little grandma, little Anzi and Xiwu are so powerful. I actually beat a big roe deer. Ha ha, we'll have a good time tonight. "

Chen nianran didn't care much about the harvest of hunting, but he restrained his smile and looked at the old farmer a little excitedly. "Uncle, do you think we can grow crops in these places, black mud fields, mixed with yellow mud fields and neutralized the mud fields?"

In a daze, the old farmer immediately looked at the yellow and black mud fields on the ground. "Well, this seems to be OK, but this is also the first year that is feasible, and there are few in the back. Unless you have to mix the black mud with the yellow mud every year. It's too much trouble. Alas, it's better to be a long-term worker and a runner out of such a laborious and laborious Kung Fu. "

Chen nianran is excited.

She waved her hand. "No, uncle, if we mix some animal excrement and plant ash to improve the soil every year, can't this plant be planted?"

"Soil improvement? Ingredients? " The old farmer didn't understand these advanced words.

Chen nianran thought about it, and he spoke patiently.

"Old man, that's it. If you want to grow plants in this yellow mud field, you need to improve the composition of the soil. It's a little complicated to be specific. I can try it out. If it's feasible, it should be popularized in a large amount next year, so that we can plant some plants in this loess field. "

Nowadays, many loess fields are only used for planting sorghum and so on.

But as Chen nianran knows, this kind of land seems to be able to grow some other plants.

She is not quite clear about what kind of soil it is. She has to do a lot of soil tests if she comes here. Once the test is successful, it means that the loess land can be greatly improved.

Thinking of this, Chen nianran can't stay any longer. He turns around and runs down the mountain.

"Little grandma, little grandma..."

Seeing her running back excitedly, Shuangxi hurriedly beckoned people to turn back.

Before we got there, we saw a carriage stop in front of the garden. The hunchback man standing beside the car, Chen nianran's eyes brightened. "Sir, why are you here?"

This, this is really too unexpected.

"Ha ha, girl, I didn't expect that we would meet again. I heard Xuan say that you have come to this place. He asked me to help him. Maybe you can use my place. "

"Er, using you?" Chen nianran is embarrassed.

"Maybe Xuan will be disappointed. I don't think the city is such a simple town. There's no concierge. The stalls are all set up in any place. For food, there are only a few tables in front. Master, you are a good business expert. I am now... " Where can I ask you.

However, the master smiled mysteriously.

With his hands on his back, he ignored the incident and asked, "you are covered in mud. Have you gone out?"

"Don't you? I've been wandering around for a while now. What kind of crops are suitable for growing here?"

"Can you tell?"

"Yes, I have a preliminary idea."

This time, sir, I was surprised.

He was looking at Chen nianran. "Well, I thought you were a capable girl. Now it seems that you are. It's not bad. It seems that I'm the right choice to let the old five with you. "

"Hey, you are right, sir. When you look at an old business, I'm sure you don't see each other. "

This is a little derogatory. At that time, she was still a little girl. The master saw that she acted in a modern way so as to pay attention. Let Zhou Aoxuan pay more attention to her afterwards, for which Chen nianran is slightly depressed. It's the same old man crossing. Why does he wilt.

"Ha ha, girl, don't say that I have a sharp eye, or I'll have a foothold. However, no matter how poisonous it is, it's not as poisonous as your family. By the way, do you have any idea after seeing the land? All I see on my way here are loess fields. Sometimes it's a bit dark, and the crops will die. This place seems to have less rain. "

It's a man with good eyesight. On his way here, he saw this place thoroughly. Chen nianran said that ginger was still hot.

"In this place, it doesn't rain at ordinary times. Once it rains, it is usually when the rainstorm breaks. Mud and other things are always washed away. In the long run, most of the mud forms in this downstream area. The upstream is seriously drained. The most serious problem is that there is too little black soil and most yellow mud here. So I'm thinking about how I can change the soil. "

The teacher's eyes were more and more bright, and he gave her a thumbs up, "yes, girl, that's a good idea. Only by neutralizing the nature of the soil can they be better exploited. This is the only way I can think of on the road. Loess land is mainly composed of alkaline soil. If you want to grow crops, you need to improve the soil and make it grow acid plants. "

This time, Chen nianran is surprised. Listen to the master's talk. How can she be kind This man knows soil science very well?

"We can change the structure of the soil. It's not just to put feces, plants and ashes. The most convenient and effective way is to put a certain proportion of sulfur powder on the ground. "

Chen nianran's heart thumped, and the people around him slowly gathered.

One by one, they listened to the teacher's instruction as if they were students' enlightenment. Until the teacher finished, the scene was silent.

"Master, come here, come here..."

Chen nianran excitedly pulled his master aside. "You and I tell you the truth. In modern times, are you a soil scientist or a so-called agronomist. Or businessmen? How can you understand so much? "
