Half a month has passed in a blink of an eye, and in this half a month, news of locusts has often come from Shandong.

One after another, people fleeing from disasters in Henan rushed to the capital, Kuang Yu followed Cheng Yuan for a long time, and his motivation was more than before.

The thousand-acre greenhouse outside the city has changed its name to a very riotous name: Zhenguo Academy.

The news was published in the People's Daily and the official newspaper, so more information about the greenhouse was sent to all officials in the Ming Dynasty as soon as possible.

Once Di Bao and Minbao publish news that is different from usual, it will immediately cause different discussions in the capital.

This is an anomaly that officials can study constantly.

The four words of Zhenguo Academy have obviously begun to gradually be noticed by officials, and of course it is also firmly tied to the words Cheng Yuan.

Many officials do not understand that it is possible to rescue the disaster just by relying on ducks, sun-dried vines, sweet potatoes, corn?

Where is the rice and wheat?

Cheng Yuan didn't have time to listen to the discussion, he gathered all the ducks that could be bought in the capital, and during this period, sweet potatoes also began to be promoted, and many people came to Zhenguo Academy to ask how sweet potatoes were grown.

In addition, in order to thank Cheng Yuan, Zhu Di gave Cheng Yuan nearly 5,000 acres of fertile land near the temple outside the city.

There is a large amount of land to grow corn seedlings and sweet potatoes.

Although it is May, the seedlings transplanted from the greenhouse are much taller than the seedlings outside.

Kuang Yu followed Cheng Yuan every day, and he was also busy, and he was going back and forth between the Zhenguo Mansion and the Zhenguo Academy every day.

Cheng Yuan often took Kuang Yu to Tai Hospital and Zhu Di.

The two of them are not black, and Cheng Yuan's originally white face is sunburned like a loach.

He also learned a lot with Kuang Yu's medical skills, and even a simple pulse cutting.

When Ji Gang and the palace attendants saw Cheng Yuan, they all laughed and joked.

The selection of doctors from Tai Hospital is imminent.

The doctors of all provinces are gearing up and eager to try.

Only Kuang is foolish and has nothing to do with himself, and he is not in a hurry, so he runs around with Cheng Yuan all day long.

He followed Cheng Yuan into the palace again today.

When he arrived at the Jinshen Palace, Zhu Di looked at his daughter's concubine and Kuang Yu was more husband and wife.

The two joked: "You two are as tanned, this is husband and wife." ”

Zhu Laosi, I'm not good at Longyang's wind......

Cheng Yuan was bearded, his eyes were staring at a dish not far away, and he couldn't help but want to ask questions.

Zhu Di put down the music, sat down at the table, looked at the person staring at his food, and cleared his throat:

"Look at what? I won't give you food today. ”

Cheng Yuan smiled, "How rare this sweet potato leaf is, it is not enough for the victims, how can you eat this, Your Majesty." ”

"Sweet potato leaves are nothing in the prime of life, but in times of famine, even the oldest leaves are better than Guanyin soil, bark and grass roots.

In order for it to be sent to the remote areas of Shandong and Henan, the minister thought that it was precious.

Turning it all into dried vegetables can save lives. Your Majesty may have a hard time swallowing this? ”

Zhu Di shook his head: "I eat when I am in trouble, there are not so many requirements, my people eat for a day, I will eat for a day." ”

Although Zhu Di learned from Zhu Yuanzhang to be thrifty, he would not eat bran every day, so Cheng Yuan asked him if he was used to it.

Who knows that Zhu Di said that he ate white steamed buns with this kind of sweet potato leaves, and he felt that the taste was not bad.

"I plan to make everyone in the palace vegetarian, when will the locusts end, I will solve this request again.

Of course, except for the imperial grandson and pregnant women, your government will also do the same. The saved grain was sent to Shandong and other places. ”

Hearing Zhu Di's supplementary conditions, Cheng Yuan nodded reassuringly.

..........

Cheng Yuan watched as the officials of Sinong Temple picked the sweet potato leaves he had planted in the palace.

He reminded: "Don't pick up the leaves in one place, you must pamper each one, and the rain and dew will be even, otherwise my sweet potatoes will not grow." ”

The official of Sinong Temple was stunned for a long time, smiled and nodded.

Kuang Yu felt that those farmers were not good at cultivating some vegetable seedlings and rice in the experimental fields, and he was worried that the seedlings would be wasted.

Angry stamped his feet and scolded.

The doctor, who should have been Svenwen, became like a farmer who loved the land like a child.

The seedlings of these experimental fields are the lifeblood of him and his master, a handful of and a handful of urine.

After thinking about it, Kuang Yu went over to discuss with Cheng Yuan: "Master, medicine books can teach people, why don't we write a few books on planting experience, and write down planting experience and pests and diseases." ”

Cheng Yuan thought about this proposal, but did not do it.

He just built a yard next to the greenhouse, in which wooden planks were placed as blackboards, and when he was not busy, he called the farmers who worked in the greenhouse together and asked them to pay attention to the problems when taking care of them.

"To heal people, we must also learn to heal the land.

This time, the locusts in Shandong, just like you said, Master, are sick, so I have some thoughts these days. Kuang Yu said.

Cheng Yuan became interested: "Then tell me what pesticides can repel insects." ”

There were definitely no pesticides in the Ming Dynasty, and it was impossible to get chemistry out of it immediately.

The Chinese people's traditional Chinese medicine is very great, and some traditional Chinese medicine can be used as pesticides.

The neem of neem can effectively control a variety of crop aphids, tea tree green leafhoppers, rice planthoppers, cotton aphids, vegetable whiteflies and other stinging pests and lepidopteran pests such as cabbage worms and cotton bollworms.

It has special effects on the control of pests such as aphids of various crops, vegetable cabbage worms, diamondback moths, yellow curved strip jumping beetles, ape leaf beetles, and 28-star ladybugs. No harmful residue, no pollution.

Cheng Yuan said: "Kuang Yu, let's go back tonight and look through the medicine book, and make good use of traditional Chinese medicine to prevent pests and diseases such as sweet potatoes and rice." ”

It was early summer, when the master and apprentice came out, the sun was scorching Ying Tianfu like a furnace, and it rained again a few days ago, and there was still rain in the earthen canals on both sides.

Except for a few homeless people entering the city, there were few pedestrians on the official road, and the leaves were wilting weakly.

The weather was hot and humid, and Cheng Yuan glanced at the inlet in the distance.

The lotus flowers in the inlet are growing very well, and several farmers are holding small boats through the lotus leaves.

The lotus leaves were separated on both sides, and a few live carp were sent to the board.

Cheng Yuan waved his hand: "Someone is coming." ”

"Grandpa Guo, what do you command?"

"Go, buy two live fish and bring them home."

Kuang is stupid, this fish is not fat at all.

Cheng Yuan seemed to see his doubts, and said with a smile: "This fish is natural, and it grows naturally. ”

The two rode back to the mansion.

Kuang Yu asked Cheng Yuan as he walked: "Last time, Master said that when there are many people in the disaster, they should be isolated and disinfected?" ”

"Yes, often in the aftermath of droughts and disasters, there is a source of infection, and in this case, quarantine is required. And the things used by the doctor should be disinfected frequently.

In this way, the source of infection will be reduced, and for infectious diseases, it is necessary to find the source in a timely and accurate manner to contain them. Cheng Yuan patiently explained.

In ancient times, a lot of people drank raw water, and they did not pay attention to hygiene, and once some bacteria and diseases appeared, the people would get sick and die in pieces, and they could die if they were infected with wind and cold.

Back at the Guogong Mansion, Cheng Yuan thought about taking the fish to the kitchen.

The fish soup these cooks make every time is too fishy, and he plans to tell him today.

In the kitchen yard, there is a mother-in-law chopping vegetables.

The tender lotus root is cut into thin slices, the taste is fragrant, and in the pot are a few live shrimp roe, washed clean yellow-orange-orange loquat fruit, which are all prepared for An Cheng.

Cheng Yuan was about to go in, when he saw the woman chopping vegetables lifting a large wooden bucket with one hand and pouring water.

He looked a little dumbfounded, and a few mothers-in-law in the house couldn't mention it.

Only Liu Dazhui, who is in charge every time, and he can lift it.

This ordinary woman is so human?
