Some things can be endured, and some things are resolutely unbearable!

Xue Lang finally raised his head, looked at Li Er, and said loudly: "There are 100,000 troops on Chuzhou Island, and not a single soldier has moved!" If you really don't want Your Majesty to be the emperor, when the princess started at the end of Wei, she was still able to raise 70,000 troops in the middle of the earthquake, and now the 100,000 army of the Navy Division is in hand, wouldn't it be more advantageous than when she was at the end of Wei? ”

"You!"

Xue Lang's words were too straightforward, and when he heard this, Xiao Li Shengren's face turned red, and he didn't know whether he was angry or ashamed.

Indeed, with Princess Pingyang's ability, in addition to the domestic servants and personal guards, there was not a single horse on hand, but she was still able to pull up an army of 70,000, let alone an army of 100,000!

What's more, although Xue Lang didn't say it, he added Xue Lang's ability to operate...... If Princess Pingyang really had different intentions, the situation would not be what it is now. Li Er wants to sit on the world steadily...... Hehe!

As for the initial construction of the Sailor Division...... That's not a problem at all! Bandits and murderers can be used by Her Royal Highness the princess as elite soldiers, and the 100,000 sailors are adapted from the garrisons of the four states!

Xue Lang paused, and said earnestly: "Your Majesty, as soon as the princess entered Beijing, she handed over the sailor token, and she didn't even hesitate for a moment, which is enough in terms of the general situation." Even if I feel awkward and a little emotional, but my princess has only been back for a few days, and as soon as she settles down, she asked the old sage to issue an edict to Yi Chu, isn't this enough to explain the attitude? ”

Xiao Li Sage was directly speechless. Xue Lang saw that he was almost stunned, clapped his hands and said, "Your Majesty, let's talk about the locust!" The clods of dirt haven't been brought in yet! ”

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

Xue Lang sighed, spread his hands and said, "So, Your Majesty, you and the princess are sisters and brothers, you two have an awkward quarrel, don't ask me if I'm okay?" I can't afford to offend Your Majesty, and I am reluctant to embarrass Princess...... The two sides are in a dilemma, and the subordinates are not very good at lying and deceiving people, let's talk about the locust plague, this is a big deal, and we can't be sloppy! ”

Nerds! Nerds! Nerds!

In the past, when his father talked about Xue Lang like this, King Qin still didn't think so, thinking that it was his father's father-in-law who buried his son-in-law, but today, his feelings suddenly became profound! But whoever is clever will take this opportunity to bridge the gap in two places, but he is good, just cares about coaxing Sister to be happy, and others don't care! I'd rather be at home than plan for the future...... Very foolish! Very foolish!

However, a certain nerd didn't feel his resentment at all, Xiao Li was silently lucky, and after a while, he ordered left and right: "Go and bring in the clods of soil brought by Xue Fuma!" ”

"Whoa."

The clods of soil were brought in, and Xue Lang began to introduce: "Your Majesty, please see, these are last year's clods, these are this year's clods, these are locust eggs!" Your Majesty can compare and see! ”

As he was talking, the palace people came to report that Du Ruhui, Fang Xuanling, and the eldest grandson Wuji were here!

Li Er announced the people in, and after the three of them finished saluting, they paused slightly when they saw Xue Lang, and there was no sameness, just when Du Ruhui saw Xue Lang, he stepped forward and bowed and said: "Ruhui has seen Xue Lang, I haven't seen him for many days, how is the horse?" ”

Du Ruhui has received the favor of Xue Lang, and it is right to see him performing. However, Du Ruhui is no longer the penniless scholar in the past, and now he is also an important minister of the imperial court, Xue Lang naturally will not accept the salute calmly, and returned the salute with a smile: "Thank you for your greetings, everything is fine." ”

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

Seeing this, Xiao Li somehow felt much better, coughed, and said loudly: "Youyang presented a sparse performance before, and the matter is serious, so I urgently ordered the three of you to come in, and discuss it after reading it." ”

As he spoke, he asked the chamberlain to take down Xue Lang's sparse music and show it to the three ministers. After the three of them finished reading, their expressions became solemn, and Xue Lang had to give science popularization on the side what a locust is and why there is a locust plague.

The ancients knew that locusts were caused by drought, but their understanding of locusts was insufficient, which led to a lot of misunderstandings in their understanding of locust plagues, and they also believed that locusts were cursed by heaven and turned into fish and shrimp eggs. And because our great China has been an agriculture-oriented country since ancient times, the locust plague has caused too much harm to agriculture, from the Son of Heaven to the officials, all of them talk about locusts.

Science is not omnipotent, nor is it enough to explain everything, for example, Xue Lang's crossing ...... Science can't explain it. However, locusts and locust plagues can be explained.

After popularizing science, what was going on with the locust plague, he pointed to the soil in the basket and explained, and said calmly: "These soils are all the soil I dug on my and the princess's Zhuangzi, as well as near the Zhuangzi. I have a vast court, where there has been a drought in the last two years, Your Majesty can send people to dig up some clods of soil quickly, so that you can have a good idea of the locust plague that will break out in the coming year! ”

After speaking, he deliberately explained how deep the soil must be dug, and where to dig the soil to dig up the locust eggs hidden in the soil, etc. Li Er made a note of it, and after finishing speaking, Xue Lang said, "There are no other questions, right?" If not, then the minister will retire! ”

Du Ruhui and the three of them glanced at each other strangely, and the round-faced brother of the eldest grandson Wuji arched his hand towards Xue Lang and said, "Xue Yuma is invited, as for the problem of prevention and control, only chickens and ducks are needed?" It's not that Mowgli suspects, it's just that the stakes are very high, and I can't help but want to verify it again. ”

The method of prevention and control Xue Lang wrote very clearly in the sparse play, however, due to the limitation of space, there was no principle of writing. Considering that the ancients knew very little about locusts, Xue Lang thought about it and simply explained in simple terms: "With the current conditions of my dynasty, after I screen, the most suitable method is two, chickens and ducks and trapping!" ”

If it is in modern times, it can also be sprayed with agricultural aircraft and other means and measures, which in the Tang Dynasty, Xue Lang did not have the ability to modulate 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 hatch should be after the beginning of spring, between March and April, it is called summer locusts, and summer locusts will also reproduce a horse, called autumn locusts, and the eggs laid by autumn locusts hatch after wintering is summer locusts." Therefore, in terms of prevention and control, the most stressful is the summer locust, and the focus is also on the summer locust. Guanzhong grows more wheat, and the most harmful is also the summer locust, as long as the summer locust is prevented, the harm of the autumn locust is not to worry! ”

The three ministers nodded again and again, and Xue Lang continued: "Locusts are also insects, and birds eat insects, which is a natural rule that everyone knows. Locusts are there every year, they have existed since time immemorial, so why do they sometimes become locust plagues and sometimes they don't? Quite simply, the effects of climate affect not only locusts, but everything in the world. Locusts in nature in the natural predators in fact, birds, frogs, etc. like to eat locusts, in the past when the climate is normal and not drought, locusts lay few eggs, coupled with birds and frogs predation, naturally will not cause disasters. When the climate is dry, birds and frogs ...... In particular, frogs will bear the brunt of the impact, originally because of the drought locusts lay more eggs, frogs, toads because of the drought has decreased, the natural enemies are almost half, and the survival of locusts is naturally more favorable, and the growth of locusts is naturally more, two by two, the locust plague is formed! Therefore, to prevent and control the locust plague, we also need to start from the rules of nature, chickens and ducks are also birds, and they also eat insects, and the natural enemies of locusts have decreased, so we will artificially increase the number of natural enemies of locusts to achieve the goal of reducing the number of locusts. Someone who grows flowers has studied that about 2,000 chickens and ducks can treat more than 100 acres of locust plague, so chicken and duck are the first choice to prevent and control locust plague! ”

Just look at the refreshing one
