A group of people asked out of curiosity: "Sir, what is this 'experimental field'?"
Liu Zheng smiled and said nothing. Liang Erfu stood up next to him and said, "Young master is planning to use it to plant new crops!"
"New crops?"
"What is this?"
A group of people were very confused.
Liang Erfu laughed loudly: "If this plant is successfully cultivated, our Yinzhou's grain output will definitely increase several times! We can harvest twice a year!"
Everyone was in an uproar and were shocked.
These farmers have always sown in spring and harvested in autumn. When have you ever heard of two crops a year? Everyone didn't believe it. Jiang Xuan, in the crowd, also sneered: "Two crops a year, this young man, I'm afraid
It’s just a fool’s dream!”
Liu Zheng didn't care about them. The fastest thing about sweet potatoes was naturally the cultivation of sweet potato seedlings. He didn't intend to hide his clumsiness in this regard. Anyway, there were all farmers he trusted, so he asked Liang Erfu to call them all over.
There are two ways to cultivate sweet potato seedlings.
The first is to cultivate sweet potatoes. This is also the method Liu Zheng plans to adopt this time. Select sweet potatoes without mold and lesions and cultivate seedlings in an environment of 35 degrees.
This is why Liu Zheng must "test the field", because in Yinzhou, there is only one way to make the fields reach this temperature in the winter! And Liu Zheng chose not only greenhouse seedlings, but also fire kang seedlings.
Combination. Because no matter what kind of seedlings are raised, film cannot be found in this era, so Liu Zheng must find a way to solve this problem.
Liu Zheng first asked people to dig out a seedbed in the experimental field, and then built a fire pit underneath - this is not difficult in Yinzhou, it is actually a stove that can light a fire. The specific process does not need to be described in detail.
After building the seedbed, sterile base soil must be used... This is a bit difficult for Liu Zheng. He definitely can't get fungicides, so he can only choose to expose to the sun for sterilization. Fortunately, when Liang Erfu left, Liu Zheng did it himself
Some soil is finally useful at this time. Then fertilize... excrement, the most natural fertilizer, and then mix it with the base soil evenly.
At this time, the fire bed needs to start burning to keep the seedbed at a temperature of 35 degrees!
Then, comes the last step.
From the sweet potatoes brought back by Liang Erfu this time, Liu Zheng selected the ones with better quality, without spots, wounds or insect pests, and then placed them in flat rows, head up and tail down, on the seed bed. Then Liu Zheng used
Fill the gaps between the sweet potatoes with fine soil, sprinkle some fine soil on the upper layer of the sweet potatoes, and then sprinkle the seedbed with water...
Liu Zheng explained while doing this.
When everything was ready, three hours had passed!
"Sir, drink some water..."
Liang Erfu brought water.
Liu Zheng chuckled: "No, you drink, I will burn it here later. Erfu, go back and bring me a bed!"
Everyone was shocked.
"Sir, why is this?"
"Absolutely not!"
"How can this place be a place to stay?"
Liu Zheng said categorically: "This is the first cultivation. The process is complicated and you can't do it. I have to watch the whole process. Stop talking nonsense and hurry up and get it for me!"
Everyone's eyes turned red.
With such a young master, why should Yinzhou worry about not being rich?
Jiang Xuan, who originally had a sneer on his face, was also looking at Liu Zheng with dumbfounded eyes.
Isn’t it just a crop?
As for being so desperate?
"Master, Erfu will accompany you!"
Liang Erfu said with red eyes.
So, Liu Zheng lived in this greenhouse. Another headache for him came, that is, he did not have a thermometer! One or two days after the sweet potatoes arrived on the seedbed, they had to be covered with film and started to heat up. Although
There is no film, but Liu Zheng still uses oilcloth instead. Although there is no sunlight, the temperature can be maintained to a large extent. When the seedbed reaches 35 degrees, the temperature will drop significantly after watering. Liu Zheng needs to light a fire to keep the temperature constant.
Back to thirty-five!
But the good thing is.
Thirty-five degrees is exactly the comfort range of the human body!
If the temperature exceeds 35 degrees, people will feel uncomfortable. Therefore, Liu Zheng has been testing the temperature with his own body in the past few days!
Of course, it sounds simple but is still difficult to operate.
