God don't even try to stop me from doing infrastructure!

For the birth of the sun salt field, the mayor wants to keep Yunze and hold a banquet.One is to thank him, and the other is to send him off, because Yunze will leave Yancheng and return to Curry the next day.

Yunze refused, he asked people to pack their luggage, and left Yancheng early the next morning.

They also passed by the village where Yunze had a fever. At that time, there were two girls from two families who were pregnant.But the child has nothing to do with the soldiers in his team, and people can't just wait for the soldiers who don't know when they will come to the door.Therefore, after a while, the two villages will organize group blind dates for men and women in need.

Sometimes the woman goes to the man's side, and sometimes the man goes to the woman's side. If the relationship is not compatible, the person who comes will leave and take away the property earned by the other party during the marriage (minus the remaining property used).But the child is the woman's by default, which seems to be a custom.

Then they left the small village and passed through the previously attacked wasteland.But there is no trace of human beings ever passing by, and nature has repainted it with a paintbrush.The wasteland has turned yellow, and the grass and trees are beginning to wither.

The team finally returned to Curry before the autumn harvest festival.The wheat outside the city of Curry has been harvested, and only cattle and sheep are grazing.Yunze noticed that there seemed to be a lot of thatched huts here, but he didn't know what they were.

When Yunze returned home, he hurriedly met with his family and found that there was a lot of salt in the house.

It turns out that the king, the priest and others have already received the sea salt delivered early, and even the "official salt store" in Curry City has opened. Although the purchase limit has been imposed, this batch of salt was still sold out within three days. The Currys ran out and there was nothing left.

It can be said that half of the problem of using salt for Taixi people has been solved, and the remaining half is how to quickly and safely deliver salt to every corner of Taixi.

"The Son of God came just in time."

Just as Yunze was about to change a suit of clothes, before he could catch his breath, he was taken away by the king for a meeting.This is another important meeting, the royal family, the temple and the elders are present, because it is about the plague of locusts.

"Plague of locusts?" Yunze's heart skipped a beat when he heard the term.This kind of biological natural disaster is not easy to solve even in modern times.In ancient times, we could only hope for nature, and it would be best if the rain would drive away the locust plague (because the heavy rain brings moisture, which is conducive to the growth of a certain fungus, which just restrains the locust. dead locust eggs).

People in this era already know the law of occurrence of locust plagues.First there is a severe drought, then there is a plague of locusts, and then there will be continued effects for at least three years, because the locusts will lay eggs, and these eggs will hatch in the following year and continue to be a plague.

The previous weather changes only reduced food production, but the locust plague will cause people in a place to completely lose crops and food. No country dares to underestimate the locust plague.

Therefore, His Majesty the King, who knew that several small countries in the south of Taixi were affected by the disaster, immediately became vigilant. He was worried that this terrible bug would come to the south of Taixi next year.It's not that this kind of thing has never happened before, and it's all a lesson of blood.

The faces of the people in the meeting were heavy, and they had learned the lesson of blood several times, but in the face of this kind of natural disaster, what can people do?It's not that they haven't tried poisonous smoke, large net fishing, etc. before, but they have no effect at all, so they should still wreak havoc.

"I have issued an order that in the southern region, all spring wheat planting will be replaced by winter wheat planting." The king said solemnly.Winter wheat can be harvested in early summer, and locusts are raging in Taixi in dry summer (Taixi is rainy in spring, which is not conducive to locust migration and reproduction), so planting winter wheat can harvest a wave before the locusts come.

When the king mentioned winter wheat, Yunze thought of a crop that could also be harvested in early summer, potatoes.

"Your Highness, I have a crop here that grows in the soil and has a high yield. If it is planted in spring, it can be harvested in three months, before the locusts arrive."

Yunze raised his hand and said, "This crop has three disadvantages. One is that it stops growing when the weather gets hot, so it can only be planted in spring and harvested in early summer, or planted in autumn and harvested in late autumn. The other is that once this plant If you get sick, the disease will spread, and the entire piece of land planted with this crop will fail. What's more, if this crop is dug out of the ground, if it is not properly preserved and sprouts, humans will be poisoned if they eat it.

"This is potatoes. Its yield is higher than golden wheat, and its taste is better than golden wheat, but its shortcomings are also obvious. If your majesty thinks it is appropriate, you may wish to plant this crop in the south."

The rest of the meeting looked at the treasure of their country, Shenzi: Did you move the kingdom of God down?

Then others began to discuss whether this crop should be promoted in the southern region next year.The first shortcoming is okay. Although the summer in Taixi is long and hot, isn’t there still two seasons for planting in spring and autumn?This shortcoming is not a shortcoming at all.The third shortcoming is that it is poisonous if it germinates, and it is not poisonous if it does not germinate. It is not surprising that some things are not poisonous when they are cooked, but they are poisonous if they are not cooked.

The trouble is the second shortcoming. Once you get sick, you won't get any crops.If someone relies on this to eat, and unfortunately the crops get sick, wouldn't it be the same as encountering a plague of locusts?

"Your Highness, how sick is the crop you mentioned?" an old official asked hesitantly.

Yunze shook his head: "Not many, this is the worst case scenario. This kind of crop can be buried a little deeper to reduce the chance of disease."

Everyone breathed a sigh of relief, and the prime minister from the left looked at the king: "Your Majesty, I think His Highness Shenzi's crop can be planted. The possibility of it getting sick is at least no greater than the possibility of locusts not entering Taixi. There must be no harvest."

The king nodded: "It's a way."

Afterwards, several ways to preserve food were discussed to help people in the southern region keep at least part of their rations.But the fundamental problem, how to reduce the losses caused by the locust plague, or how to reduce the extent of the locust plague, no one spoke.

It's not that they avoid talking about it, but that they really don't know what to do.

Yunze was also dazed for a while, mainly because he really couldn't think of any better way to eliminate the locusts.What he knows now are all the barrage comments from a certain website back then, and everyone knows that there are experts per capita on a certain website, so Yunze doesn't know if these methods are useful or not.

"Your Majesty, I've heard of some ways to reduce locusts, but I'm not sure how effective it is. Maybe you can try it." After hesitating for a while, Yunze decided to believe in the barrage again.

Like last time, he asked someone for a wooden board, white cloth and ink pen: "Let's first analyze the reason why locusts can continue to cause disasters for several years. It's very simple, locust eggs, they left enough locust eggs A female locust can lay dozens of eggs in the ground at a time, and they hide deep in the soil, making it difficult to find them. These eggs will hatch after a month and continue to reproduce."

"If the next year is no longer dry, but rainy, too much water will drown the eggs of locusts, that's all. But basically, the drought will not last for one year, so the locusts will be a plague again in the next spring. They eat up the south The food from several countries continues to go north, and it can reach Taixi in summer. Taixi has high temperature and little rain in summer, and it is also a good breeding ground. Then the locusts will stay in January and February, and will not disappear until the rainy season in late summer.

"The best time to kill insect eggs is summer, but because it happened in other countries, we can't go to other people's homes to kill insects, so we should also take measures in our own country. I suggest that the land should be turned over again before winter, and It has to be dug up and scattered. The heavy snow will freeze the insect eggs inside, including locusts. This is the first way.”

After Yunze finished the first article, he looked at everyone's feedback. If no one objected or refuted, then continue.

"Secondly, let's take a look at what locusts are afraid of. Locusts are a disaster, and every time there is a drought, why? First, because the drought leads to food shortages, the locusts change shape due to the impact of the environment. We can call it 'swarming'. There are An obvious feature is that the body has changed from yellow-green to yellow-brown, from separate ones to clusters.

"Second, the drought has caused locusts to lack natural enemies. Many animals around us use locusts as food, such as birds and frogs. But after entering the drought, the birds and frogs disappear, and the locusts have no natural enemies, so they will reproduce unscrupulously.

"Three, there is actually a curse (fungi) specifically for locusts, which must exist in a relatively humid environment. Once there is a drought, this curse (fungus) that can control the number of locusts is difficult to work. There are fewer locusts An enemy."

Yunze spoke carefully, and the people below listened with great interest.They just like to listen to Shenzi's analysis of things. It's hard to describe, but they feel very clear, organized, and persuasive.After listening to it, they will establish a very clear concept in their minds, and will consider all aspects, and have a deep memory.

In modern terms, it is full of dry goods and very targeted.

In fact, this is one of the golden fingers of modern people. The habit of sorting out, summarizing, asking questions, and solving problems developed in classroom education can also be said to be logical thinking ability.

The meeting room was still quiet, everyone was staring at Yunze, only the clerk was desperately taking notes.

They felt that since Yunze listed one, two, and three reasons for the formation of the locust plague, shouldn't it be time to talk about ways to alleviate the locust plague?

They guessed right, Yunze began to analyze one by one, how to fight against this natural disaster.

"So, we can see that when locusts become a plague, there must be a unique environment, that is, drought. It is formed due to drought, and then migrates to low-lying and humid areas. Along the way, they will lay eggs in bare land. The locust plague continues Continuously, causing huge losses.

"Theoretically, land with high water content and dense vegetation cover is not suitable for their reproduction, so we can artificially create an environment without bare soil. That is, intercept rivers, create artificial lakes, and regulate water and soil. Or, like Like the canal diversion system in the library, the water is fully utilized. Even if the rainfall decreases, the land will still have enough water, which is not conducive to the growth and reproduction of locusts.

"Of course, this may be a big project, and we won't see concrete results in a year or two. But in the long run, it will have a huge effect on combating drought and locust plagues, so, Your Majesty..."

Yunze looked at the king. The king covered the money bag. He knew that he had to spend money again, and not in one lump sum, but in the same way as the water supply system in Curry. The mowing will not be finished until this year.

But can he say no?With so many people watching, can he refuse?

Yunze looked at the king and whispered 'salt'.

It was like a life-saving rope, which brought His Majesty the king back in one fell swoop.Yes, this year he has salt, and there is a steady stream of salt.When his salt specialty stores opened all over Taixi, wouldn't the money continue to flow into his pocket?

His Majesty the King immediately revived with full blood. He stroked his beard and said righteously: "In order for the people of Taixi not to be invaded by locusts in the future and to keep their own food, the artificial lake must be built."

He didn't talk about repairing the water supply system. This thing consumes too much stone and cement. The city of Curry alone squeezed out more than one-third of his graves. Can the southern region be a city?That's several cities!His Majesty the King felt that he might not be able to afford such an expensive luxury water supply system.But it is still possible to dig artificial lakes, and others have plenty of them.

It is enough to intercept the water source and build an artificial lake. Yunze returned to the previous topic: "Maintaining moisture in the land and keeping the vegetation dense can fundamentally reduce the number of locusts, but at present, these measures will not take effect immediately. , it will take some time. So is there any other way to effectively curb the number of locusts? Yes."

He wrote a line on the white cloth: "Increase natural enemies of locusts."
