Chapter 590

These days, with the means of transportation and horses, Feng Lanchu has been exploring the grassland outside.

And Wang Bingbing has been doing research in the grassland disaster area. Among them, how to abuse the little assistants? They can write 30000 word papers, which will not be repeated here. In short, most of them are tears.

After three days of investigation, on the fourth day, Feng Lanchu and Wang Bingbing did not go out. Instead, they met to discuss the research and conclusions of these days.

They were sitting in the office with notebooks and a thick stack of materials in hand.

Wang Bingbing started his work elaboration first. He's been checking the grass samples these days. From the grass stem to the soil layer analysis, the results show that everything is in the normal range, and there is no problem of diseases and pests.

"I think the most serious problem of this grassland is trampling, just like the place where people often walk does not grow grass. Now this grassland also has this situation. So, in theory, as long as we leave this place idle, we can grow grass again soon. "

"But how fast this will be, well, I can't guarantee it, because the climate of the plateau is still different from that of our South."

Everyone was surprised to get Wang Bingbing's conclusion. They never expected the test results to be so simple.

The presence of only wind haze beginning is not surprised, she smiles to take out their own information.

"The results of my report here are similar to those of Professor Wang. The real culprit of this time's pasture decline is not pika. "

"What's that?" Wang Binbin is very interested in hearing that Feng Lanchu says that the result is the same as him.

"If my investigation is not biased. Then, the main reason for this time's Grassland desolation is not natural disaster, but man-made disaster. "

"Man made disaster?" The administrator was shocked, including Jiang Anzhi, Zhu zhengkui and Cai Jiao.

The breeze haze beginning calm ground nods.

"After a few days of investigation, I found that there were no wolves or birds in the places where the villagers lived. Listen, it has nothing to do with pikas. In fact, these are pikas' natural enemies. They hide deeper because they are afraid of human beings. Without natural enemies to control the number of pikas, they will naturally proliferate crazily. That's why pikas suddenly proliferate. "

The reason for the increase of pikas has been found, but what is the reason for the decrease of grassland? This is not enough to get rid of the suspicion of pika! The crowd looked confused.

"Of course, it's not that the grassland reduction has nothing to do with pikas. It's just a very small reason, but the main reason is the serious man-made damage, including the cattle and sheep raised by people."

"They consume a lot of forage every day, and they trample on the same place again and again, consuming it every day. No matter how strong the regeneration ability is, it can't last so long."

"As Professor Wang said just now, if people walk too much, they will become roads. If cattle and sheep trample too much on the grass here, it will not grow much. Maybe last year, the grass here had been in a weak state, but it changed a little bit, and people didn't find it. It was only after a serious deterioration that people found out. And it happens that pikas are breeding crazily in recent years. People blame pikas for the withering of grasslands. "

Everyone was shocked at the conclusion. What can we do?

Feng LAN Chu shook his head helplessly: "returning grazing to forest is the best way."

But she did not recommend that the whole village be moved to a new place.

Because a new place can live for ten years at most, and eight years will be exhausted, and then there will be endless relocation.

So? How to return grazing to forest?
