"I'm sure it won't rain for half a month." Qin Fan said firmly.

"As for why I'm so sure, you should be able to predict the heavens!"

"But it doesn't matter, it's important that we plan for the next drought and locust plague!"

Qin Fan said as he observed the reactions of several people.

Sure enough, after listening to his words, Lao Li's face was already scorched.

Others are also worried.

I really didn't see the wrong person.

Qin Fan knew that the group of people in front of him were all first-class nobles of the Tang Dynasty.

At least what they said would influence the decision of the Heavenly Khan.

So in fact, whether Datang is drought or not does not have much impact on them.

It is the people who suffer the most.

And they, no matter what, will have a bite to eat.

But their expressions at the moment are unpretentious.

They are really worried about the livelihood of the people of Datang.

And the abnormal behavior of several people on Qin Fan's side also attracted the attention of others.

Changle and a few people walked over.

"Daddy, Uncle Sun, what's wrong with you?" Changle couldn't help asking.

Hearing this, Li Shimin spoke: "Datang is going to be a drought, and there may be a locust plague next." We're figuring it out. ”

Hearing this, Qianqian was stunned for a moment and said:

"Childe, didn't you write a copy of "Six Methods of Controlling Locusts" for Zhao Xiuzhu? Can we use it here? ”

"Six ways to cure locusts?" Hearing this, Li Shimin's eyes lit up.

It turned out that Qin Fan had already prepared!

Qin Fan frowned: "The countermeasures recorded in that book can only be applied to a small area. ”

"But today's drought is the drought of the entire Tang Dynasty."

"When the locust plague breaks out, it will also sweep half of the Tang Dynasty."

"If this is the case, then the six methods of controlling locusts are of little significance, and they can only be relieved slightly, but they cannot cure their roots."

Hearing this, the eldest grandson Wuji spoke:

"Anyway, as long as it works a little! It's better than sitting still! Qin Fan, boy, let's talk about it first. ”

Hearing this, Qin Fan nodded and said:

"Good! These six methods are mainly based on the locust's habitat, food sources, spawning grounds and other aspects. ”

"Reducing the impact of locusts through their habitat, cultivating their natural predators, and planting crops that locusts don't eat."

Li Shimin nodded: "So how do you do it?" ”

Hearing this, Qin Fan said helplessly, this is also what worries me:

"For example, it cuts its living environment."

"Locusts like low ground, so they can think of it as a pond."

"But one place and two places can be, the headquarters can stop farming in the whole Datang and change to fish farming!"

Li Shimin nodded: "What about other measures?" ”

"For example, planting trees to improve and reduce drought areas so that locusts have nowhere to lay eggs."

"The Gobi Desert, like the outside, is the best place for locusts to lay eggs."

"But if you want to improve the Gobi, you can't do it in a few words!"

"It must be the efforts of a generation to turn the yellow sand into a green space."

Hearing this, Li Shimin was also a little helpless.

Just as Qin Fan said.

Environmental change doesn't happen overnight.

Even if he can requisition the people of the world to plant trees in the Gobi Desert.

But the survival of trees is a problem.

Sometimes a single sand storm can wipe out all your efforts.

"In addition, the method of cutting down on its food sources does not apply to the entire Tang Dynasty."

"On the one hand, the locust plague is now a foregone conclusion, and the harvest of food grown by the people is imminent."

"What the people eat, the locusts eat! Then it will be the man and the locust who will fight for food. ”

"You can't reap the grain before it's ripe! The grain thus harvested is also unpalatable. ”

After a pause, Qin Fan continued:

Even after this year, this method of control will only apply to some locust-prone areas (this chapter is not finished!). )

District. ”

"Locusts love to eat crops such as rice and wheat, so we grow soybeans and other grains that locusts don't eat."

"Although there is a huge difference in production, it is not a complete harvest."

"But you can grow crops like potatoes and sweet potatoes. Even if the locusts eat their stems and leaves on the ground. ”

"But the potatoes and sweet potatoes we eat are buried in the ground and won't be hoho."

"However, there is another problem with this."

"Plots like ours near Chang'an can certainly grow sweet potatoes."

"But in the paddy fields like Jiangnan, you can't give up planting rice and plant sweet potatoes instead!"

Sweet potatoes and potatoes, although easy to feed, do not pick the environment.

But if the soil is too wet, it still can't be planted.

For example, rice fields are difficult to grow at all.

The cultivation of a piece of soil often takes years or even decades of effort.

To convert a hard-earned paddy field into a dry field in response to locusts would be to put the cart before the horse.

Hearing this, Li Shimin also sighed deeply.

Indeed, as Qin Fan said.

These methods are easier to adopt in a certain area, after all, there is the entire Datang for scheduling.

It's a big deal that there is no yield here, and other plants are planted.

Grain and grass can also be transported from other grain-producing areas.

But if half of the Tang Dynasty is plagued by locusts.

These methods can only be slightly alleviated, and many of them are not applicable as Qin Fan said.

Seeing that everyone sighed for a while, Qin Fan coughed lightly:

"However, among my six methods, there are two other methods, which are basically common in most areas, and there will be no negative impact."

Hearing this, hope ignited in Li Shimin's eyes again.

The eldest grandson Wuji also complained: "You kid, you love to pant when you speak!" Look at what worries us. ”

"The first thing is to exterminate locusts by creatures!"

"Biological locusts?" Hearing this, Li Shimin was a little surprised.

"Not bad! The so-called biological extermination of locusts is to let the people raise more chickens, ducks and geese. ”

"This locust plague is a disaster for our people."

"But for these poultry, it's a buffet feast!"

"When the locusts arrive, release the poultry, and they can mitigate the impact of the locust plague to a certain extent!"

"And when the poultry eats the locusts, the eggs will be bigger. This is an alternative compensation. ”

Hearing this, Li Shimin nodded.

Although this method cannot completely eradicate the locust plague, it can at least reduce the impact of the locust plague and add an additional benefit to the people.

"What about the other method?"

"Another way is to make a special batch of pesticides and spray them."

"These pesticides are harmless to the crops, and they don't cause damage to other organisms in the field, except for locusts."

"It can poison locusts!"

Hearing this, Li Shimin immediately said:

"That's a good idea! Just get this pesticide! ”

But Qin Fan shook his head: "The production of this pesticide is not easy. ”
