At that time, when Dr. Man and Dr. Liu went to see Hao Jianshe to ask about implant issues, the other party was very excited.
He threw out a lot of questions about the black soil, and Shi Man was unable to get a word in.
Faced with the other party's eager eyes, Shi Man was silent. Why was the black soil so productive and where did it come from? How could she explain this?
If I can't explain it, I'll just reply with "I'm not sure, I don't understand, I don't know".
Hao Jianshe instantly became dispirited.
But after just a few seconds, he applied to end the quarantine early, wanting to observe the black soil up close and conduct research.
Shi Man still refused, the principle of three days of isolation could not be broken.
"So how much of this high-yield black soil is left? You're not going to use all this precious soil to plant fruit trees, are you?"
Shi Man felt that if he said he had planted all the seeds, this physically weak agronomy professor in front of him would probably turn into the Hulk and strangle him to death.
Doctor Liu glanced at Shi Man as if he was enjoying a show.
Shi Man looked calm and said, "Don't worry, there's still at least 100 square meters. I'm planning to build a high-yield planting area, so I came to ask for professional advice."
When he heard that it was only 100 square meters, Hao Jianshe seemed very disappointed, but he was more tempted.
"If the natural disaster continues, food will be a huge problem. If, as you said, black soil not only produces high yields but also shortens the crop maturity cycle, I suggest planting potatoes and sweet potatoes first."
"The growth cycle of these two crops is 3-5 months. The only things we need to pay attention to are pests and diseases and fertility issues."
"Potatoes consume a lot of soil fertility."
Shi Man nodded. She felt that the high-yield black soil was not a problem in terms of soil fertility. In addition, there was a one-month acceleration period, so she had stockpiled a lot of potatoes and sweet potatoes.
At that time, some potatoes had sprouted, so she collected them as well, thinking that they would be easier to plant.
After discussing these, Shi Man asked about the seeds again, and heard Hao Jianshe say:
"In recent years, my father's research topic has been high-yield grain varieties, and we have also cultivated many new grain varieties, but unfortunately, these grain varieties are all in the school's seed bank."
Shi Man's mind moved: "Now that the city is flooded, can the seeds in the seed bank still be used?"
Hao Jianshe pondered, "There are many ways to preserve seeds. Generally, low-temperature areas are equipped with generators, so even if there's a power outage, it won't affect their preservation. But now it's flooded, so even if there are generators, they're useless."
"However, in addition to low-temperature storage, there are also vacuum storage methods. This part of the high-yield grain will definitely be fine."
