Back to that night, she flirted with the cold-faced rough man

Chapter 249

In order to find out the reason, Bai Ying confirmed with Wang Jinyu again.

Wang Jinyu nodded and said, "Yes! We raise silkworms on our farm three times a year, except in winter. I was sent here last autumn. By then, the autumn silkworms had already grown up, and I was only responsible for helping the old silkworm farmer. In the winter, the old silkworm farmer passed away. Fortunately, he taught me the silkworm rearing methods before he died. At the beginning of this spring, Captain Ding gave me full responsibility for the silkworm room."

"Although I've never raised silkworms before, I've asked the farm elders, and they've also had their young silkworms die, but never in such large numbers. I still don't know the specific reason. Hatching was fine, and as soon as the silkworms hatched, I fed them fresh mulberry leaves every day. I just don't know why they died right after eating them. At first, I thought the leaves were dirty, so I washed them before feeding them, but they still died! I had no choice but to dissect the dead silkworms and discovered they died from diarrhea due to the excessive moisture in the mulberry leaves."

Bai Ying's face twisted when she heard Wang Jinyu's detailed description of her dissecting of silkworms, even including her hand movements.

After all, she was a barefoot doctor and was not afraid of bloody scenes.

Only!

I was afraid of round insects that looked like silkworms, but I didn't expect Wang Jinyu to dare to dissect a silkworm... It seems he was forced to this point.

Wang Jinyu tugged at her pigtails in distress. "I really don't know what the problem is! If all the silkworm eggs die, I won't be able to meet the production quota, and I'll be lucky if I don't get criticized. Maybe... there's no hope for me to go back in this lifetime."

As he talked more and more, Wang Jinyu's mood gradually became depressed.

"Sister Jinyu, don't be discouraged. Together we can help you find the cause of the silkworms' death..."

Bai Ying was lost in memories of her past life.

With the reform and opening up, the state supported members in raising silkworms and making silk in order to generate foreign exchange. At that time, their commune also encountered similar difficulties. Silkworm farmers suffered heavy losses due to the large-scale death of silkworm seeds. Many families lost everything. Seeing that no one wanted to raise silkworms anymore, the commune invited an old professor from the provincial agricultural university to provide guidance.

After some investigation by the old professor, he quickly found out the main reason for the mass death of silkworm eggs.

In the 1970s, with the invention of Jinggangmycin by an academician from the Shanghai Pesticide Research Institute, which could solve the problem of rice sheath blight, large quantities of pesticides such as BHC and DDT began to be produced in 1976 and gradually put into use.

Years of abuse of pesticides have caused adverse effects such as agricultural product pollution, poisoning of humans and animals, and environmental degradation. Although it was urgently stopped later, the adverse impact on the environment is irreversible because these pesticide ingredients are non-degradable.

Silkworms are the most sensitive creatures to environmental changes. They are so sensitive that even if the air where pesticides are sprayed is contaminated with the slightest smell of pesticides, let alone spraying them on mulberry leaves, the silkworms will die immediately.

Therefore, the old professor gave two solutions to this situation.

One is that if silkworm farmers pass by an area where pesticides are sprayed, they must change their clothes before feeding the silkworms and cannot feed the silkworms while wearing contaminated clothes.

Also, if there are pesticide residues on the mulberry leaves, you can soak them in vinegar water, bleach solution, alkaline water, atropine detoxification solution, etc. for half an hour, then take them out, wash them with clean water, and dry them in the sun before feeding them to silkworms.

Thinking of this, Bai Ying looked up at Wang Jinyu and asked again and again, "Sister Jinyu, is there any farmland next to the mulberry garden being sprayed with pesticides?"

Wang Jinyu was puzzled. “Yes, there is arable land, but it’s planted with peanuts. It’s not time to spray pesticides yet.”

"peanut?"

Bai Ying paused.

Was she wrong? Wasn't the pesticide the cause of the mass death of the silkworms Wang Jinyu was managing?

Just as she was feeling a little discouraged, Bai Ying thought of a key point that she had overlooked!

Peanuts are different from other crops because they bear fruit underground. The most important step is to mix pesticides into the soil in advance.

In 75, Shandong Province invented a pesticide that can be mixed into the soil, phoxim granules. This pesticide can effectively prevent and control underground pests such as peanut grubs and mole crickets.

The farm had just planted peanuts a few days ago, and the mulberry orchard was close by. It's very likely that the silkworms absorbed the pesticides that had degraded in the soil, causing the mass death of the silkworms...
