Not all the ministers are divided into grains. Many people have also heard this poem. After waking up, Boyi and yang xian have come over in vain. "Can this manure field be as fertile as rotten grass?"
Yang xian nodded "more effective"
The princes were excited when they cried, regardless of the smell in the air. What’s more, they bowed to the seven captains of Luyue Xiyuan.
The direct consequence of the decline of soil fertility is, of course, the decrease of crop yield, which is different from natural disasters for farmers.
Reducing production means that hungry people are likely to starve to death.
Therefore, in order to maintain the fertility of the land, farmers can adopt fallow and rotation tillage, and the original method is either three years and two seasons, or planting chestnuts in one season and then planting beans in another.
There is nothing rotten grass, but the effect is not so remarkable, and it is obvious that the West Park has achieved good results with such a big fight
Yang Xiandao said, "Human and animal dung stoves are dusty, but once they enter the fields, they will turn into cloth, silk and millet."
Being chosen to accept the truth, it’s all traceable
When the West Park was first built, Hu Ximei regarded chicken excrement as a link in the Sangji fish pond. Now it is not surprising that yang xian says that they have worked together to make manure.
Several ministers of the people’s livelihood gathered up the courage to watch carefully next to the pit.
The doctor Yao Zhong said, "Since the manure can be fertile, why dig a hole to put the manure in the middle?" And it seems that these feces are mixed with other things? "
Yeah, why are you digging a hole? Is it not strong enough? Have you seen hoarding food, seen hoarding goods and hoarded shit?
……
Chapter 266 athel Loren buff!
Yang xian stroked his burnt beard and smiled. "This manure can be fertile, but if fresh manure is applied to the field, it will not be fertile, but it will burn seedlings. It is necessary to put the manure for a while before applying the manure to the field. This was discovered by Lu Daochang."
Lv Yue cleared his mind and said, "At that time, I thought that ordinary weeds could only fertilize the soil with rotten grass, so the feces must also rot."
"Dig a big pit like this and then put the human and livestock manure in the West Park, add plant ash, usually put the leftover livestock bones in the house into ashes, and break the straw and then pour the urine in the urine bucket at ordinary times …"
"After a few days, slag fertilizer and liquid can improve the fertility of the land, and according to my observation, ordinary insects dare not approach it, but they still have insect repellent effect."
Zhu Zhen kept throwing leftover bones and pig’s trotters into the pit with a big belly.
I also made great efforts, and half of these livestock bones were contributed by my old pig.
After listening, I retched for a while.
The merit of Lu Yue is really a little hard. Don’t waste your bragging that you are the first person in the sect to do such a thing.
I was surprised at the thought of the consequences of manure coming out.
Manure is as cheap as paper.
I am very worried that this year Chentang will vigorously promote wheat and rice planting. If manure is still half of the land that can’t grow anything, the rest may be 70% of all the land in previous years.
No, no, on second thought, it’s different. I’m too worried
Chaoge here, even if Yuan Hong and others are quite popular, they are whatever they say. Who knows who Yuan Hong is?
People in other places have never seen manure, and I’m afraid I feel guilty. After all, I have to pour filth like manure into the fields.
Don’t worry too much if the court doesn’t carry manure and promote it vigorously.
"That was a blaze of fire?"
Ministers have also looked at yang xian. Yeah, how can manure still burn?
Yang xian meaningful look to the eldest brother Yuan Hong Yuan Hong tilting head some Yan see people.
"Look at the position". yang xian took out a bamboo tube to cover the pit and made a snap of his fingers to give birth to a small flame. As a result, a slightly cracked bamboo tube actually emitted a yellow and reddish flame.
"This …"
It’s not that bamboo tubes burn. Bamboo tubes can’t be ignited so quickly.
There’s something weird about this scene. The bamboo tube burns like a jack-o’-lantern.
"This is what Lu Daochang once said when the gas from the bamboo tube burns, which is called biogas."
"Biogas … biogas …"
I am familiar with this scene when some people have a heart attack.
Lv Yue got biogas out?
"This bamboo tube is connected with cow intestines, fish glue, cowhide, etc., and it goes straight around the pit. I didn’t expect that feces can not only turn into fertilizer, but also burn gas."
Yang xian is very excited. How big is this merit?
Although biogas was developed by Lv Yue alone, manure was explored by them together. It was only a few years since the animal husbandry and virtue mountain in Jiaxiyuan was built, and it took hundreds of years to practice hard in the mountain!
"Ha, ha, ha ….." The quick way "This biogas can burn, ha, ha, ha ….. put this out first and blow it up"
"I can know that the fire explosion is caused by biogas."
Yang xian put the rag in his hand back into the bamboo tube and threw it directly to the ground
Being scared in a cold sweat means you’re a monster. Lu Yue is a fairy artist. Dare to do so?
The pit where excrement is fermented is a refugee biogas pool!
In case the biogas digester is detonated, Dashang should change his country name today.
Fortunately, nothing happened.
I couldn’t help wiping my forehead with a cold sweat. He realized that the explosion was a biogas digester, not a fight or gunpowder.
"I want to make more manure and send it to farmers to see the effect, so I dug several pits in the West Park and I know that manure is the most important thing in this West Park."
"My brother was so impetuous that he dug a new pit and placed excrement and sundries. He forgot to measure the depth of the pit, then lit it and wanted to measure it with a measuring tool, but he forgot that Lu Daochang told me to detonate the pit, which led to flames …"
The ministers were relieved. So that’s it.
So it seems that the seven captains of Xiyuan are not mortal!
That way, the fire can be completely damaged
Looking at Yuan Hong a face of shame sample all suppress a smile.
The pit is full of feces. What would it look like if it were blown up?
