Space peasant girl: sweet and sassy

Chapter 75 The Hand Sprayer

and the word "poison"
Listening to it makes people feel a chill down the spine!
Although Grandma Luo didn't know what kind of poison Feng Bai was going to make, she was the mastermind, ah, no.
She is the proposer.

Therefore, she knew very well what the use of Feng Bai's "poison" was.

He immediately explained to his granddaughter, "It is a poison that can kill weeds without affecting your continued farming."

Luo Xiaojiu almost understood.

She looked at Feng Bai and asked, "Grandma means you can make a herbicide, and it won't hurt people, right?"

Herbs that kill weeds and replant vegetables
This is similar to modern paraquat, as long as it is used in the right amount, it should not hurt people.

Feng Bai nodded, "Well, this medicine is decocted from several kinds of herbs, and the amount of medicine produced is about the same as that of ordinary traditional Chinese medicine."

"If you pour it directly on the weeds, it will seep into the field."

"So, I want to fry more medicine. You can put it in a special bucket, dip the wicker into the medicine and sprinkle it on the weeds."

"In this way, weeds can be eliminated, and the potion sprinkled on the field can be used to prevent other weeds from growing."

Feng Bai finished speaking.

Luo Xiaojiu became more and more certain that the medicine had the same properties as modern pesticides.

However, she frowned slightly, "You said that the potion can prevent the growth of weeds, but does it also prevent the growth of vegetables?"

It is good to be able to stop weeds, but if it stops the growth of vegetables, then she might as well not use it.

Feng Bai smiled lightly, "Don't worry about this, because it's just the potion sprinkled on the field, and the amount of the potion is only used on the surface."

"You need to turn over the soil when planting, and the effect of the medicine will dissipate after a small amount of medicine on the surface meets the moistened soil on the inner layer."

In fact, it is the principle of evaporation with the water in the wet land.

Luo Xiaojiu completely understood this time.

But what Feng Bai said about sprinkling water with wicker is too slow and laborious, so it's better to replace it with a modern hand-operated sprayer.

Modern have electric sprayers and foggers.

In ancient times, there was no electricity, so she could make a hand sprayer.

In modern times, she once helped grandma spray pesticides, and she also disassembled the hand-operated sprayer, and the principle of making it is very simple.

The beautiful almond eyes narrowed slightly, and she asked Feng Bai again, "Can you make the medicine less and thicker, I want to mix the medicine with water."

Feng Bai really didn't think of this just now.

He just wanted to fry more medicine, Xiaojiu can directly use the medicine he boiled, and there is no need to add additional water.

Listen to her now.
He also smiled, "Alright, then I will try to increase the dose of medicine and reduce the amount of medicine, so that it is convenient for you to carry."

His idea is that Xiaojiu can directly take the thick and thin medicine to the land that needs weeding, mix it with water, and then sprinkle the medicine with wicker.

As a result, Xiaojiu put down his bowl and chopsticks and went straight to his Westinghouse.

She skillfully found the pen, ink, paper and inkstone from his drawer, and then she didn't forget to say to him, "Borrow it."

Feng Bai was curious about what she was going to do, so he put down his bowl and chopsticks and followed.

I saw Luo Xiaojiu quickly grind the ink, and then began to draw something on the paper.

Feng Bai watched intently, and Luo Xiaojiu also focused on painting, neither of them noticed that the door of Westinghouse was quietly closed by Grandma Luo.

Grandma Luo: Give them more time to be alone, so that the little great-grandson can come out earlier!
Luo Xiaojiu drew a sprayer pattern on the paper.

But the sprayer does not require mechanical principles like a small stall, so she drew the spray rod, pump and other parts under the picture of the sprayer.

Feng Bai can understand the picture of her hand-operated sprayer, but he can't understand the principles of her following constructions?

After all, the hand sprayer uses air pressure.

This technology is rarely used in this day and age.

Luo Xiaojiu patiently explained to him the use of parts and the principle of air pressure.

Just seal it up.

At the same time, some of the materials Luo Xiaojiu mentioned were not available in ancient times, but he quickly thought of other things to replace them.

There is no plastic in this era, and Feng Bai's suggestion is to use iron sheets instead.

Luo Xiaojiu felt that the material of the iron sheet was expensive, and the junction of the iron sheet might not be very tight, so she wanted to use gum.

There are no rubber trees here, but there are many trees that can produce gum. They can collect these gums and use them to replace rubber to make plastics.

Or again.
Luo Xiaojiu suddenly thought of processing gum and molten iron together, which might make the iron not too hard and increase the tightness.

She shared her thoughts with Feng Bai.

Feng Bai thought about it, and felt that her idea was okay.

Hearing that he agreed, Luo Xiaojiu immediately wanted to go to the woods to find a tree with gum, but because he was too excited, he forgot Feng Bai beside him.
As soon as she got up, she bumped her head against Feng Bai's forehead.

Feng Bai couldn't help saying in a low voice, "Uh."

His fair forehead suddenly flushed red.

Luo Xiaojiu quickly realized that his little iron head had hit someone, and hurriedly apologized, "I'm sorry, I'm sorry, I didn't mean it."

The little one is kind of cute.

Feng Bai couldn't hold back, and hugged her into his arms, his deep voice was numb and provocative, "It's okay, just hug her and it will be fine."

Lo wine.
Unexpectedly, I dislike him a little bit!

With a heavy face, she decisively pushed him away.

Coincidentally, this time I ran into Feng Bai's wound again, but this gave someone Feng a chance to pretend to be sick, and immediately cried out in pain
"Uh, it hurts."

Seeing him clutching his wound, Luo Xiaojiu felt worried, and hurriedly stepped forward to ask him, "Did I touch your wound just now?"

"No, it's not torn, is it?"

Feng Bai curled up, seeing her worried appearance, he secretly rejoiced in his heart but didn't show it on his face, he said aggrievedly:

"I don't know, it just hurts."

Luo Xiaojiu was in a hurry, and wanted to untie his shirt to check whether the wound was torn, but Feng Bai held his little hand again.

Feng Bai's long and narrow phoenix eyes evoked evil charms, and whispered close to her ear, "Actually, it doesn't hurt too much."

Someone in Luo who realized that he was being fooled!

The little foot stepped on Feng Bai's big foot fiercely, and asked with a sneer, "Does it hurt now?"

seal white
numb!

In the kitchen, Grandma Luo stood at the door and eavesdropped, and when she heard that Luo Xiaojiu seemed to have been sealed off at the end, the old man was full of sympathy.

Tsk tsk, Xiaobai is not easy either.

Then the door was opened from the inside, and Grandma Luo quickly pretended to be okay and walked into the yard, not forgetting to tell her granddaughter:

"Let's go out after drinking and eating!"

Lo wine.
Feng Bai also walked out.

Although he didn't realize that the door was closed at first, but later he noticed that Grandma Luo had come to eavesdrop, and silently thanked her.

What a helper.

Luo Xiaojiu didn't go to the woods immediately after lunch. She suddenly remembered the strawberry sale yesterday, so she went to a few franchisees' homes first.

Because it was meal time, several franchisees were not at home and were still selling goods outside, so Luo Xiaojiu first found a few people who were at home.

She talked to several people about selling strawberries and asked their opinions.

Several people heard that they really wanted to sell strawberries.

Luo Xiaojiu gave each of them a few catties of strawberries for a trial sale.

First, it is to see the shipment volume in rural areas, and second, it is also to expand the advertising volume of strawberries more widely.

Let more people know.

In the later stage, she wants the villagers who are farming to sell a large number of fruits and vegetables.

Finally, she went to the woods.

As soon as she arrived in the forest, she felt as if someone was staring at her behind her.
