However, Emperor Chongzhen thought about it and understood what was going on.

Potatoes and sweet potatoes are alien species after all. To achieve such a per mu yield, it requires generations of cultivation, and selection of the best among the best can ensure an increase in yield.

As for the current yield per mu, it is excellent for the Ming Dynasty.

Planting one acre of potatoes or sweet potatoes can catch up with three or four acres of wheat. This is definitely auspicious existence for the Ming Dynasty, where disasters occur frequently.

People are red when they are hungry. Not to mention eating tree bark or eating soil, it is very common for Yizi to eat each other.

"What about corn production?"

Emperor Chongzhen calmed down, walked forward, helped Xu Guangqi up and said.

"Your Majesty, the corn has not been harvested yet."

Xu Guangqi bowed and said, "According to my observation, the maturity period of corn has not yet arrived, but judging from the situation I have learned, the yield per mu is also amazing.

At least more than twice as much as wheat.

However, the specific yield will be determined after harvesting, peeling and weighing.”

As an agricultural expert in the late Ming Dynasty, Xu Guangqi had extremely strong abilities in crop cultivation and planting.

"This is indeed auspicious for the Ming Dynasty."

Emperor Chongzhen nodded slightly and said, "Since potatoes and sweet potatoes are so effective in planting in imperial villages in various places in northern Zhili.

That means there is no problem in planting in the North.

The next thing to do is to start large-scale planting in various prefectures and counties in northern Zhili. Xu Qing may become busier in the future and the burden on his shoulders will be heavier."

"It is worth finding a living thing for the people of the Ming Dynasty to death even if you exhaust your ministers!"

Xu Guangqi couldn't hide his excitement and said: "If corn yields are excellent per mu, then we must even change the cultivation method of the Ming Dynasty, especially in the north, a crop of wheat and a crop of corn.

Adjust the climate according to the season.

If such a thing can be done well, it will definitely be a great thing that benefits the present and the future.”

The large-scale planting of corn, sweet potatoes and potatoes requires periodicity. In the eyes of Emperor Chongzhen, it would take at least ten years to popularize the planting in various parts of the Ming Dynasty.

After all, as the group that understands farming the most, the change of main crops has been implemented for a long time.

"This thing needs to be done well."

Emperor Chongzhen thought for a while and said, "If the agricultural sciences under Xu Qing are understaffed, you can ask the inner court to continue to supplement them.

As for the money you need, don't worry.

What Xu Qing has to do is to use the shortest period to solve the food security for the Ming Dynasty. Next year, I will try planting in Beizhili, and I will solve all the problems for Xu Qing."

"I obey the order!"

Xu Guangqi bowed and responded.

Grain production is one of the benchmarks for measuring whether the country is strong. After all, compared with others, grain cultivation has a longer period of time, and it takes more effort to get more rewards.

"By the way, the agricultural science and technology side needs to start developing how to increase the yield per mu." Emperor Chongzhen thought for a while and said to Xu Guangqi: "Just like when a person is weak, he should use tonics to warm up.

So can the land fertility decline be supplemented in a similar way?

Xu Qing should pay attention to this matter, conduct more research on this aspect, and develop a fertilizer for the land to enhance grain yield per mu."

"I obey the order."

Xu Guangqi bowed again.

What Emperor Chongzhen said opened up new ideas for Xu Guangqi and asked him to start thinking about this matter. If he could really develop a fertilizer to enhance grain yield per mu, then the food security of the Ming Dynasty would be even more unfavorable.
