Settled in the Tang Dynasty

Chapter 544 Prevention and Control
Some things can be tolerated, and some things are absolutely unbearable!
Xue Lang finally raised his head, stared at Li Er, and said loudly: "The [-] army on Fuzhou Island has not moved a single soldier! If you really don't want your majesty to be emperor, the princess was still able to rein in the army when she was born at the end of the century. With [-] Megatrons in Guanzhong, now that the Navy has an army of [-], wouldn't it be more advantageous than when it was in its infancy?"

"you!"

Xue Lang's words were so straightforward that Xiao Li's face turned red, and he didn't know whether he was angry or ashamed.

Indeed, with Princess Pingyang's ability, she had no one at hand except her family and personal guards, and she was able to pull up an army of [-], let alone [-]!
What's more, although Xue Lang didn't say anything, but with Xue Lang's management skills... If Princess Pingyang really has a different heart, the situation will not be what it is now.Li Er wants to sit on the world peacefully... Hehe!
As for the initial construction of the navy... that's not a problem at all!Bandits and murderers can be used by Her Royal Highness as elite soldiers, but the Hundred Thousand Navy Division was adapted from the garrisons of the four states!

Xue Lang paused, and said earnestly: "Your Majesty, the princess handed in the navy token as soon as she entered Beijing, without even a moment's hesitation. In terms of the general situation, it is already enough. Even if I feel awkward and a little emotional, But my princess has only been back for a few days, and just after she settled down, she asked the old sage to issue an edict of Yi Chu, isn't this enough to explain her attitude?"

Saint Li was rendered speechless.Xue Lang saw that he was almost angry, clapped his hands and said, "Your Majesty, let's talk about the locusts! The soil clods haven't been brought in yet!"

Xiao Li didn't speak, looked at Xue Lang's luck silently, gritted his teeth and said, "If you didn't know that Sister didn't mobilize a single soldier, do you think the matter of you two leaving your post without authorization can be let go so easily?"

Xue Lang sighed, spread his hands and said, "So, Your Majesty, you and the princess are siblings. If you two are having trouble, don't ask me if you're okay? I can't afford to offend your majesty, and I can't bear to make things difficult for the princess... It's difficult for both sides. I'm not very good at lying and deceiving people, let's talk about the locust plague, this is a big deal, don't be sloppy!"

fool!fool!fool!

In the past, when his father talked about Xue Lang like this, King Qin didn't take it seriously, thinking that his father-in-law buried his son-in-law, but today, the feeling suddenly became more profound!Anyone who is clever will take advantage of this opportunity to bridge the gap between the two, but in the end he is lucky, he only cares about making Auntie happy, and others don't care!I'd rather be idle at home than plan my future... I'm so stupid!Stupid!

However, a certain idiot didn't feel his resentment at all, Xiao Li was lucky in silence, and after a while, he ordered the left and right: "Go and carry in the soil clod brought by Mrs. Xue!"

"Here."

When the soil clods were brought in, Xue Lang began to introduce: "Please look, Your Majesty, these are the soil clods from last year, these are the soil clods from this year, and these are locust eggs! Your Majesty can compare them!"

Just as they were talking, the palace servants came to report that Du Ruhui, Fang Xuanling, and Changsun Wuji had arrived!
Li Er announced the people in, and the three of them finished their salutes. Seeing that Xue Lang was there, they paused for a while, but there was no change in expression. When Du Ruhui saw Xue Lang, he took a step forward, bowed his hands and said, "Ruhui has seen Xue Lang." Son-in-law, long time no see, how is the son-in-law?"

Du Ruhui has received Xue Lang's kindness, so seeing him perform the ceremony is the right thing to do.However, Du Ruhui was no longer the penniless scholar in the past, and now he was also an important minister of the imperial court. Naturally, Xue Lang would not accept the gift calmly, so he returned the gift with a smile and said, "Thank you for your greetings, everything is well."

After that, there were no more words.Du Ruhui also knew the rumors that this son-in-law was not good at socializing, and now he experienced it personally, and felt that it was really profound.

Seeing this, Xiao Li felt much better for some reason, coughed, and said in a loud voice: "Earlier, You Yang presented a melody, and since it's a big matter, I hurriedly ordered the three of you to come in, and discuss after reading it. "

As he said that, he asked the servant to take down Xue Lang's melody and show it to the three ministers.After the three of them finished watching, their expressions became serious. Xue Lang couldn't help explaining what locusts are and why locust plagues occur.

The ancients knew that droughts caused locusts, but they did not know enough about locusts, which led to a lot of misunderstandings about locust disasters. They also believed that locusts were the scourge of heaven and were transformed from fish and shrimp eggs.And because our great China has been an agriculture-based country since ancient times, the locust plague has caused too much damage to agriculture. From the emperor to the officials, everyone talks about locusts.

Science is not omnipotent, and it is not enough to explain everything. For example, Xue Lang's time travel... science cannot explain it.However, locusts and locust plagues can be explained clearly.

After popularizing the science about the locust plague, he pointed to the soil in the basket and explained it, and said calmly: "These soils are the soil I dug on the Zhuangzi and the princess's village. I went to It is vast, and where there has been drought in the past two years, His Majesty can send people to hurry up and dig some soil clods and come back, so as to know the locust plague that will break out in the coming year!"

After finishing speaking, he specifically explained how deep the soil should be dug, where to dig the soil to dig out the locust eggs hidden in the soil, and so on.Li Er asked someone to write it down, and after finishing speaking, Xue Lang said: "Is there no other question? If not, then the minister will leave!"

The three of Du Ruhui looked at each other strangely, Changsun Wuji, the round-faced elder brother, cupped his hands towards Xue Lang, and said, "Mr. The matter is of great importance, and I can’t help but want to ask for proof again.”

The prevention and treatment measures Xue Lang wrote very clearly in the play, but due to space limitations, he did not write the rationale.Considering that the ancients knew very little about locusts, Xue Lang thought about it, and simply explained in a simple way: "Based on my current conditions, after I screen, the most suitable methods are two, chickens and ducks and trapping!"

If it is in modern times, agricultural aircraft can be used to spray pesticides and other measures. In the Tang Dynasty, Xue Lang did not have the ability to prepare pesticides. Of course, it can only be considered from the biological chain.

Xue Lang said: "The habits of locusts, the first batch of locust eggs should hatch after the beginning of spring, between March and April, they are called summer locusts, and summer locusts will breed one, called autumn locusts, and the eggs laid by autumn locusts survive the winter After hatching, they are summer locusts. Therefore, in terms of prevention and control, summer locusts are the most stressful, and the focus is also summer locusts. There are many wheat crops in Guanzhong, and summer locusts are the most harmful. As long as summer locusts are controlled, autumn locusts will be harmed. Nothing to worry about!"

The three ministers nodded repeatedly, and Xue Lang continued: "Locusts are also insects, and it is a well-known natural law that birds eat insects. Locusts exist every year and have existed since ancient times. Why do they sometimes become locust plagues and sometimes not? It’s very simple. The impact of climate not only affects locusts, but also affects everything in the world. Locusts have many natural enemies in nature. Birds, frogs, etc. like to eat locusts. In the past, when the weather was normal and not dry, locusts laid eggs In addition, the predation of birds and frogs will naturally not cause disasters. When the climate is dry, birds and frogs... especially frogs will be the first to be affected. Originally, because of drought, locusts lay more eggs, frogs, The toads have decreased due to the drought, and almost half of the natural enemies have gone. The survival of the locusts is naturally more beneficial, and there will naturally be more locusts that grow. When the two are added together, the locust plague is formed! Therefore, to prevent and control the locust plague, we need Starting from the rules of nature, chickens and ducks are also birds and eat insects. The number of natural enemies of locusts has decreased, so we artificially increase the number of natural enemies of locusts to achieve the purpose of reducing the number of locusts. Some flower growers have studied it, about [-] Chickens and ducks can control more than [-] acres of locust plagues, so chickens and ducks are the first choice to prevent and control locust plagues!"
