After seeing the Yuchi area, Yan Changqing continued to walk forward with Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes.
Then he stopped in front of a huge square, turned around and looked at the square:
"The area we are in now is the killing area!!!"
“All the marine fish we caught from the sea yesterday will be unloaded to the previous fish pond area, and then transferred from the fish pond area to here for slaughter.
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes also turned their heads and looked over when they heard the words. When they saw a huge square covering an area of several acres.
Among them, water channels made of cement are criss-crossing, dividing the square like a large chessboard.
The underground water pipes that control the urban water supply system continuously transport seawater here.
Then, through the criss-crossing small water channels, the preliminarily filtered and clear sea water is transported to each chess grid in the square.
In each chess grid there is a "243" chair with a backrest for people to sit on. In front of the chair are a chopping board and a kitchen knife.
On the left side of the chair, there is a transparent glass water tank about three feet in diameter. There are various sea fish in the water tank.
Thousands of fisherwoman workers from Haizhou City, recruited through labor recruitment, sat on chairs and wore the gloves issued to them.
From the transparent glass tank on the left, take out the fish one by one, put them on the chopping board, slaughter them, remove the fish scales, remove the internal organs, and then throw the fish internal organs into the large transparent glass tank on the right.
Then put the slaughtered fish into the water channel beside you, and use the flowing water to remove the blood, mucus and blood stains on the surface of the fish, as well as the blood on the abdomen.
The flowing water will take away fish scales, fish blood and other impurities together, and then flow into the sea through the underground channel in front of the square and the underground drainage system.
After rinsing the fish, place the slaughtered fish on the bamboo rack on the right side of the chair.
From time to time, someone would push a small trolley and pass by the fisherwomen and workers.
Or replenish their nearly empty glass tanks with new fish to be slaughtered.
Or take away the slaughtered sea fish piled up around them.
Or remove the large glass tank that has been filled with fish offal and replace it with a new, empty large glass tank.
The whole process can be said to be orderly and smooth.
However, with the arrival of Yan Changqing, Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, the fisherwomen and workers who were actively working began to feel a little commotion.
Because the news that Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes had promised in public that people all over the world would be able to eat meat every now and then also reached here.
Faced with a prince who cared so much about common people like them, they also wanted to express their feelings.
Fortunately, the steward here got orders from Yan Changqing and told them in advance when they saw Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes.
Don't make a fuss, continue to do your own thing seriously and hard, this is the best reward for the princes Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes.
Therefore, the most the fisherwomen and workers could do was secretly glance at Prince Zhu Biao, Zhu Chong, Zhu Fan, Zhu Di and other princes, but they did not do anything else.
Yan Changqing continued walking and introduced:
"The workers in this area are mainly responsible for the slaughtering of marine fish. The slaughtered marine fish will be placed on the bamboo shelf nearby.'
"Then other workers passing by will transport the slaughtered fish to the pickling area for pickling."
"And the offal of the slaughtered fish will also not be wasted."
"Because fish offal is rich in a variety of fertilizer substances and trace elements, it can well supplement the fertility of the soil and convert nutrients into fertilizers that can be absorbed by plant roots."
"To put it simply, fish offal can be used as land fertilizer, thereby making the land fertile and increasing food production!!!"
Prince Zhu Biao, Zhu Fang, Zhu Fan, Zhu Di and other princes were originally just listening with calm expressions.
After hearing the last sentence of Yan Changqing, "Fish offal can be used as land fertilizer, thereby making the land fertile and increasing food production."
Even though I was interested, I still had a strong interest!!!
As a descendant of Yan and Huang, no one can be indifferent to methods to increase grain production.
Especially in this era where food is the most important thing for the people, the food problem has always been an issue that no one can get around.
Even princes like them are no exception!!!
Therefore, Prince Zhu Biao couldn't help but ask:
"How to use those fish offal to make the land fertile and increase food production?!!"
Zhu Cang, Zhu Fan, Zhu Di and other princes also stared at Yan Changqing with their bright eyes, waiting for his answer.
Yan Changqing smiled and said without hiding anything:
"There are three methods, one is direct landfill method."
"However, this method depends on the planting environment and species. Generally speaking, ground-planted crops can be used if there is deep soil.
"However, if it is a potted plant or some plants with a weak root system, then this method cannot be used."
"For some crops grown in the open field with relatively developed root systems and strong growth."
“You can dig deeply away from the roots, bury the fish guts directly, and cover them with thick soil to avoid contact with flies.
"Then the fish offal is allowed to ferment and mature in the natural environment, and finally it is slowly absorbed by the roots of crops and plants."
"In this way, the odor will not be too great, and the effect as a land fertilizer is also good."
"The second method is composting, which is currently the most commonly used and most practical retting method here."
“Using original soil, adopt a stacking method, with one layer of soil and one layer of organic matter, such as fish offal, peel, eggshell, bones and other kitchen scraps piled behind the warm soil.
"We often use our rice water for irrigation, and the top layer of soil must be kept clean to avoid the proliferation of fly maggots."
"With the isolation of the soil, high temperature is generated inside for decomposition. When the temperature is high in summer, it can be retting and matured in one to two months.
"There is no obvious odor after opening, so it can be used as land fertilizer."
"This method also doesn't have much odor, and the fertilizer effect is also good."
"The third method is the soaking method."
"Place the fish offal and some other items in the container, add water, and close the lid."
"The lid must have air holes to prevent a large amount of gas from being produced during fermentation, which may cause overflow."
"Then it is placed in a warm place and fermented for about a month before it can be used as liquid fertilizer."
"The liquid fertilizer produced by this method has the best effect and is rich in nutrients, but it has an extremely strong smell!!!"
"If it's made in a closed space, the smell will be like falling into a cesspit that hasn't been dug out in years!!!"
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other 1.1 princes all memorized the three methods of making land fertilizer from fish offal mentioned by Yan Changqing.
At the same time, it was unanimously decided that if possible in the future, the people under the rule would be allowed to make this kind of land fertilizer, especially the most effective liquid fertilizer.
As for the stench caused by making liquid fertilizer, Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes did not care at all, and neither did the people of the Ming Dynasty.
What’s wrong with the smell?!
If being stinky can make them produce two more kilos of food, then no matter how stinky they are, they will still smell "good"!!!
In this era, apart from being hungry and not having enough to eat, there is nothing else that cannot be endured!!!
