"After several times of transplanting, the yield will drop significantly, just like a person suffering from a disease. My grandson has also arranged for people to study it, but there is no solution yet."

Yam crops are buried underground and are most susceptible to virus invasion. Zhu Ying is not an encyclopedia, nor has he memorized an encyclopedia, so he naturally does not know how to get rid of viruses.

This involves knowledge related to chemistry in later generations. Obviously, given the current situation in the Ming Dynasty, it will be difficult to deal with detoxification methods for a long time.

However, sweet potatoes, potatoes, and corn are particularly easy to grow, and they do not occupy the same living space as rice fields. In addition, they are cold and drought tolerant and do not require care. For the people of the Ming Dynasty today, it can be said to be real gospel.

Moreover, if the three crops are planted in rotation, even if they are really affected by the pathogen, the most stupid method will be adopted, which will cause tuber failure and corn moldy areas. The crops will be directly destroyed to block the spread.

Then replace it with new seeds and it can still be maintained.

But obviously, detoxification technology needs to be studied from now on.

Over in the Western Region, there are currently not many breakthrough developments in the field of detoxification, but there is still some experience in how to protect potatoes and corn, which have been planted for many years.

"Even if it's less, to what extent will it be less?" Zhu Yuanzhang couldn't help but ask.

"Even if the yield is reduced, as long as it is not impossible to produce seeds and the yield per mu is several hundred kilograms higher, there will still be no problem. Regarding the planting experience, I have recorded it in a book and will distribute it together when the time comes. At the same time, I will strengthen the research on these crops.

, I guess the problem won’t be too big.”

"While we were talking about this, my grandson discovered that Uncle Wu has a strong interest and rich experience in agriculture. He is planning to set up an agricultural school in Daming to study everything related to crops."

"I just want to ask my fifth uncle to help my grandson and set up an agricultural school together to protect my food supply in the future."

As Zhu Ying finished speaking, Zhu Yuanzhang couldn't help shouting: "What a great idea!"

"Dasun is indeed Dasun. This idea is really good. It is a good agricultural school, dedicated to the study of various crops, mainly to increase the yield per mu. If we can make a breakthrough, the people of Ming Dynasty will not have to worry about having nothing to eat.

."

Now Zhu Yuanzhang's face was rosy with excitement, and he felt that his eldest grandson was completely a gift from God to him.

Whether it is matchlock guns or high-yield crops, it is completely conceivable that it will definitely cause earth-shaking changes for today's Ming Dynasty.

By then, the Ming Dynasty will be rich and powerful, the people will no longer suffer from hunger, and the army will have powerful firearms.

Is there anyone in this world whom I cannot fight?

In the past, Zhu Yuanzhang was worried that his eldest grandson would be militaristic, but now it seems that he knew too little.

Having mastered what Da Sun said, who can still restrain Feng Lang Ju Xu's thoughts?
