Song Yuanhuanzhi

Fu Yuanzhi not only helps to catch insects in Xiaozheng's field every day, but also stays in other people's wheat fields. This stay lasts for half a day.

It's just that Fu Yuanzhi hasn't been able to find anything wrong with it.

The setting sun gradually fell behind the mountain peak, and the afterglow sprinkled a layer of gold on the whole village.

Fu Yuanzhi poured the heart diggers he caught into the chicken coop of the master's house.

After Fu Yuanzhi finished this series, he walked unhurriedly towards Li Zheng's house.

When Fu Yuan's road crossed a small stream, a group of half-grown children were swimming in it and having water fights.

When Fu Yuanzhi walked under a big tree on the bank, he saw a child in patched cloth clothes, about seven or eight years old, with a small rock under his buttocks, and he looked up from time to time into the stream. From time to time, his companions used the sticks in their hands to poke back and forth on the ground.

Fu Yuanzhi knew this child. The other party was a child of Xiao Zheng's family. He stepped forward, knelt down and said, "Niuboy, why don't you go with them?"

Niu Wa looked at the adult whom his father had always praised on the opposite side, first stood up very politely and called Fu Yuanzhi respectfully, and then said, "My father and mother won't let me play in the water."

Fu Yuanzhi touched Niuwa's head, and then asked, "What did you poke with this branch just now?"

Hearing this, Niuwa pulled away the loess that had just been covered, and a caterpillar emerged from the small hole.

Just as Fu Yuanzhi was about to say something, he suddenly realized that something was wrong with this caterpillar.

Fu Yuanzhi picked it up, and the caterpillar no longer had that fleshy feeling, as if it had stepped from a young age to an age when it was about to step into a coffin. Under its body was a yellow cocoon, which looked like a coffin as a whole. The caterpillar hugged the yellow cocoon tightly.

And the whole cocoon has been punctured by Niuwa, revealing small white cocoons inside.

It was the first time Fu Yuanzhi saw a caterpillar like this, and he asked curiously, "Where did you catch it?"

Niuwa pointed to the Fanmai field not far away.

……

Fu Yuanzhi took this unique caterpillar away, and he observed it carefully all the way. Although he didn't know why, it might be because he hadn't found anything for half a month, which made him feel a little different about this caterpillar. The place seems to be fussing.

Fu Yuanzhi returned home and put it in a small wooden box.

He suddenly smiled.

He was so frantic that he brought it back obsessively.

Fu Yuanzhi sighed and ignored it.

But four days later, when he saw a wireworm coming out of the belly of a mantis on the road, Fu Yuanzhi suddenly had a flash of inspiration.

Words that he had heard before suddenly appeared in his mind.

parasitic.

Madame once said that some insects live in other insects.

So, can heartworms also parasitize?
The parasitized worms will die because of the birth of the host, so the heart diggers can be easily solved without their help!

Moreover, Changliu Village has such a large planting area, and the number of heart digging insects is not as many as that of Dasinongsi. Can he boldly guess that there may be parasitic heart digging insects in places other than Xiaozheng?

Fu Yuanzhi's footsteps that were about to go back stopped instantly, and he directly turned around. He urgently needs to do an experiment now!
After Fu Yuanzhi ran away for a certain distance, he felt inconvenient and ran back again, so he asked Li Zheng to help.

The two slings of money prepared by Fu Yuanzhi will be gone in one day.

The reason is that Fu Yuanzhi asked Lizheng to help tell the villagers to sell all the heartworms they caught in the wheat field to Fu Yuanzhi.

The villagers in Changliu Village have never seen such a rare thing that a nobleman wants to buy worms, and everyone can't help but feel suspicious, but since Yuri said this, everyone has the attitude of giving it a try. Lost, lost, but the chicken at home just missed a meal.

This kind of good news swept across the entire Changliu Village in an instant, and everyone threw themselves into catching bugs one after another.

Fortunately, Fu Yuanzhi made the precondition that it must be a heart-digger from his own field. If he pretended to be from another place, he would have to cancel it all.

Fu Yuanzhi's identity is still deterrent, no one dares to play tricks.

Fu Yuanzhi's goal was achieved. There are many people and strength is great. Fu Yuanzhi separated the packed wooden boxes according to the names of the characters. For example, if the ones from Uncle Gao's house were delivered, they would be labeled "Uncle Gao's house, 35 pieces".

Of course, there is a comparison, and the comparison is the heart digger in Xiao Zheng's field.

If it proves that the heartworms in the wheat fields other than Xiaozheng's are parasitized, and that the rice in Changliu Village is not greatly affected, then they can start from this aspect!
Since Fu Yuanzhi wanted to conduct this experiment, he never went out of Lizheng's house, except to go out to get the cut wild vegetables or guava leaves, and stayed behind closed doors at other times, observing their changes all the time.

Although it is very slim, Fu Yuanzhi still has to try again. Knowing the natural enemy of heart diggers, the rice in Beijing will be able to grow as smoothly as in Changliu Village!
Fu Yuanzhi didn't know what the current situation in the capital should be like, but in order for Song Yi to resist for a longer time, Fu Yuanzhi felt that he had to write down the breakthrough point he found.

Now that he has found a solution, Song Yi will not always be at a disadvantage.

Fu Yuanzhi's letter was indeed timely, with a breakthrough point, Song Yi's confidence greatly increased.

Of course, he didn't think of a way.

Now, he also has some ideas.

Since people can be poisoned to death by medicine, why can't insects?

Song Yi came up with this idea and ran to the clinic every day, but the clinic was for doctors, so Song Yi had to return disappointed.

What can poison people can definitely poison insects, but if the insects are poisoned in this way, how can we eat food?
So Song Yi's move is destined to not get results in the medical clinic.

However, there are many roads that cannot be followed by one road, the difference is just that there are some detours.

Since the heartworm harms wheat, millet, sorghum, beans, etc., list them one by one and eliminate them one by one.

Why do heartworms get these grain damage, but other species don't, is there something that can get rid of it?
Once Song Yi understood this one, he could also understand other joints when he thought about it.

After this, not only Fu Yuanzhi was doing experiments, but Song Yi was also doing comparative experiments through hard investigation and research.

What kind of scallion solution, leek solution, bitter gourd leaf solution, garlic solution, etc., as long as it is not eaten by heart diggers, he has tried them all.

Don't ask to kill it, but also smoke it away!

It's just that he took away some of the spider mites in the rye, and some of the heartworms were still strong.

Song Yi thought it might be because they were in the ears of wild wheat, and the solution was less, so they couldn't smoke it at all.

After guessing this possibility, Song Yi directly prepared to use irrigation. Because of the large amount of work, Song Yi could only select some experimental sites to carry out the experiment. After making sure everything was safe, he proceeded to the next step.
