Chapter 306: Bugs can see it, but I can’t?

Before dawn the next day, Sun Jianping got up, yawned, and went to the rice fields to see the results of last night's experiment.

He stayed in the rice fields until midnight last night, and after replacing two candles in the bottle, he couldn't bear it anymore and returned home.

On the birch pole, there is no light in the two large lanterns made of glass bottles. Only a layer of burnt wax oil is left sticky on the wire, while the net bag below is sinking. You can tell at a glance Lots of goods.

Sun Jianping stood on tiptoe and took off the net bag. Oh my god, it was full of captured insects!

Many of them are still alive and crawling around inside!

Lao Cao came over with a water pot, and Sun Jianping pulled the bottom of the net bag and poured out all the insects in it!
It’s half full of water!
Lao Cao was dumbfounded!
so much!
"Uncle, look, that melon-seed-sized thing with the powder on its body is the rice borer. If this thing lays eggs in the rice stalks, what hatches will be big white bugs. This is called the leaf roller..."

"We finally planted some rice, but all these insects, big and small, are causing trouble!"

Lao Cao hated it so much that his teeth itched!
Another insect trap was also filled with various flying insects, which was enough to fill a bucket of water. Lao Cao took these insects home and fed them to the chickens, almost killing the old hens.

One has two. In view of the fact that it is too laborious to change the candle, and there is an open flame, which poses a safety hazard, inventor Sun Da thought hard and thought of a good way.

Use a battery, two wires and a small light bulb tied together to make a simple flashlight and put it in a glass bottle.

One battery is enough to keep this little light bulb burning overnight!
This solves the trouble of changing candles in the middle of the night, and there is no safety issue without an open flame.

As for the effect...

It was getting dark again, and Lao Cao looked at the lights shining inside the rice - rice would stop earing under strong light at night, so Sun Jianping modified the glass bottle again and put a layer of black dye on the outside. Paper, use a knife to cut a few slits, which greatly reduces the light, but does not affect attracting insects.

The small lamp turned on, and rays of light shone straight in all directions, looking very strange.

Lao Cao felt a little pain in his head.

The effect of these two glass lamps was good, so Sun Jianping kept up his efforts and made seven or eight more, which were hung in every corner of the forty rice fields. As soon as it got dark, simple light-emitting devices made of batteries and small light bulbs were put in.

The bugs gave up eating the delicious rice and swarmed into the glass bottle. Once inside, they never wanted to come out again!
The next day, three large water bugs were poured out of ten glass bottles!
All the old hens in the village are eating meat!

"This thing is great. It requires no work, no pesticides, just a few batteries, and all the bugs are eliminated!" Xu Jinshui looked at the simple insect trap version 3.0 hanging on the rice field, swinging back and forth in the wind, standing vertically Thumbs up!

"No, these lamps are very troublesome!"

Lao Cao looked at the vibrant rice fields with a smile. Although pesticides are easy to use, they are not provided by the supply and marketing cooperative for free. They always cost money!

And it’s also very expensive!
The most commonly used pesticide now is 666, which is a highly toxic pesticide. A few years ago, the agricultural technicians of the Taipingshan Brigade died from drinking this.

Recently, the supply and marketing cooperative has sold a brand-new pesticide called 1605, which is even more sinister than . When mixing this pesticide, you must wear long-sleeved clothes and rubber gloves, and you must apply soapy water on your body and face to avoid poisoning.

If there really is a large-scale insect pest outbreak in the rice fields, Lao Cao would have to spend his money to buy pesticides. However, it seems that the effect of these lights is very good. The rice fields are growing well, and many rice plants have bloomed and eared as scheduled. It seems that the season has passed in August and it will start to get cold. By then, the insects will not be able to jump even if they want to.

"Yo, good stuff!"

A middle-aged man's voice came from a distance. Old Cao Xun was stunned when he heard it!

This is not...Sun Jianping's second uncle, Sun Changguo!

"What gust of wind brought you this rare guest here!" When Lao Cao saw it was him, he was overjoyed. He hurriedly took a few steps forward and shook hands with him!

"The Academy of Agricultural Sciences sent me down to investigate the growth of this year's crops and check the stability and resistance of the seeds. Where is Jianping?"

"Working in the fields, Jianping, Jianping, come out quickly and see who's coming!"

Lao Cao shouted into the rice field, and a tall and handsome young man emerged from the waist-high rice waves, holding a handful of weeds in his hand. Sun Changguo laughed when he saw it!
good boy!
After a few months of not seeing each other, my fair skin has turned slightly bronze, my arms have become fleshy, and there are dark stubbles on the corners of my mouth!

The brat who hugged my thighs and asked for sweets has now grown into a strong young man!
"Second uncle!"

Sun Jianping was overjoyed and struggled to pull his feet out of the mud. He ran to his second uncle with long strides and called out affectionately.

"Good boy, your body bones are getting stronger and stronger. Is this the rice you are planting this year? It's not bad, but the season is wrong. Logically speaking, this month should have been filled long ago. Why are you so busy growing flowers?"

"I can't do it this year. I'm repairing canals and begging grandpa and grandma to find a rake. By the time I plant the seeds, I'm already more than ten days late..."

"We usually get frost in September, so late, I'm afraid the rice won't be able to grow..."

Sun Changguo sighed, and Old Cao's heart skipped a beat when he heard this, "Then... Uncle, see what you can do to save the day. Don't work hard for a year. In the end, you can't even eat rice. Then our village People should not die of embarrassment!"

"Let's talk about it then. It just so happens that Yu Xin and the others are going to the countryside to join the queue in a while. I will follow you then and help you think of a solution."

Sun Changguo could only comfort him like this.

"That's good. If you, a great technician, take action, we can save this year's rice!"

Lao Cao was delighted and suddenly felt reassured.

Sun Changguo sighed, squatted beside the rice field and inspected it carefully. He couldn't help but secretly praise in his heart. Although this batch of rice was planted more than ten days late, it is definitely growing well. The roots are thick and the leaves are dark green. There are many tillers. They have already sprung up. The rice ears are neatly arranged. If they are arranged well, the yield this year will be quite good!
"You guys are very attentive to the care here..." Sun Changguo looked at the insect trap hanging on the birch pole with interest, "It's just that, Jianping, you seem to have used the wrong light."

"Uncle, you are talking about a black light. I have also read about it in books, but there is no place to buy it."

Sun Jianping scratched his head and smiled naively. Sun Changguo opened the briefcase he carried with him, took out a whole box of small black light bulbs and handed it to him, "Those of us who are engaged in agriculture must prepare what kind of things at any time. Shi, I bought this box a few days ago to be used in the rice experimental field of the Academy of Agricultural Sciences, but I haven’t used it yet, so I’ll leave it to you first!”

Black light?
Lao Cao was stunned. There is also a black light lamp?

"Well, Chang Guo, why does the country produce this thing? You said that when this lamp is lit... it is pitch black. What's the use if it's not lit?"

Seeing his confused look, Sun Changguo smiled and explained, "Brother, the black light is... how to say, it doesn't emit black light, but emits something that we can't see with our eyes, but can be seen by insects." A kind of ultraviolet light. When insects see this light, they will fly over..."

"Ah...bugs can see it, but I can't?"

"Yes!"

Lao Cao scratched his hair in frustration, "Then I'm worse than a bug!"
