After a while, the children had almost finished harvesting.

Fang Ye glanced at the rice field, blew a whistle, and clapped his hands: "Okay, let's tidy up the rice cut here and rest for a while!" If you want to threak millet, you can try it, and I will take you to dry the millet later. ”

Some children hurriedly raised their hands and said, "Mine hasn't been cut yet!" ”

Fang Ye smiled: "There is not much left, let's leave a little for the birds to eat!"

Although the fields are planted by us, we also rely on the various organisms in the fields to grow healthily.

Take it from nature, and give back to nature. ”

Some children are not very reluctant: "Eh~~ Isn't this a waste of food!" ”

After all, it was the rice that I had planted so hard, and my back hurt after planting the seedlings, and my legs and stomach hurt for several days!

Fang Ye thought for a moment and said, "Tell me a story about the Oriental White Stork!"

There are about 6,500 Oriental white storks in China, and last winter, 5,000 migrated to Tianjin for the winter.

In previous years, there were never so many because the several wetlands along their migration route did not have enough food.

Together, these Oriental White Storks are easy targets for poachers, and their frequent ups and downs can also lead to electrocution on high-voltage lines.

Without enough food, they had to eat the fish from the villagers' fish ponds, which were driven away by the villagers with firecrackers, and finally volunteers raised money to buy fish for them to build a canteen, which temporarily solved the crisis.

Due to human activities, many wetlands have disappeared or are being destroyed.

Among the threats to wetlands, in addition to the reclamation of land around the lake, there are also dredging boats that dig a lot of river sand on the riverbed and lakeshore.

The country's large-scale urbanization over the past few decades has created a high demand for sand, which is used in glass, concrete, and building materials, and the ideal sand for industry comes from rivers and lakes rather than from the ocean.

The rice field is equivalent to a small wetland, which can allow birds to stop and resupply when they are tired of flying.

While our human community is growing, we should not forget to leave some living space for these wild animal neighbors.

Of course, the most important thing is to protect their habitat. ”

"Oh!"

After listening to what Fang Ye said, the child blinked his eyes twice, and looked watery as if he was about to cry: "Then can you leave them a little more?" ”

Fang Ye squatted down and touched the child's head, and said gently: "Okay, the bird who came here to rest will definitely thank you~"

A parent lamented: "In the past, when we harvested in our hometown, we would deliberately leave some wheat, corn and sweet potatoes unharvested, just to leave some food for the wintering animals. ”

"This kind of agriculture that is eco-friendly and gives back to nature is really good!"

"Eh, our hometown used to hate migratory geese very much, because they would eat wheat, and goose velvet could be exchanged for foreign exchange, so they were beaten off a lot, and then they didn't dare to come to settle down with us...... If I had the opportunity now, I would definitely be kind to them. ”

"While our human community is growing, don't forget to leave some living space for our wildlife neighbors, that's a great saying!"

Not only the children, but also the parents who listened on the ridge felt that they had learned a lot!

My impression of the zoo has always been that it is a place to relax and relax, see elephants, see pandas, and feed two pieces of meat to tigers.

However, after visiting Linhai Zoo, I gradually learned to appreciate the natural behavior of animals and understand their survival needs.

There are a few fields in the zoo, thinking that the children can exercise, get rid of the problem of pampering, and know the rare food.

Unexpectedly, although there are no rare animals in the rice field, it is like a window showing the way of harmony between man and nature.

The harvest far exceeded expectations.

After the children finished threshing, Fang Ye called the keeper of the small farm and took a bag to pack the beaten grain.

Take away the rest of the unfinished ones and let the machine handle them.

"Come, let's clean up the rice stalks! The rice stalks are also very useful, not only can they be fed to alpacas, they can be used as straw mats for animals to sleep on after drying, and they can also be used to ferment with manure and turn into fertilizer! ”

Fang Ye put the unfinished rice in a small cart, waved his hand, and said chicly: "gogogo!" Let's deal with that first. ”

There is a small brick house behind the small farm.

The area is 300 square meters, but the walls have not been painted, and it is very simple.

This is the rice processing room, where various machines are placed, and it is usually used as a storage room for farm tools.

Fang Ye greeted the children and said, "Everyone follow me to visit in an orderly manner, keep your distance, don't touch it blindly!" Parents also help to watch the dots! ”

When the children came in, they all looked left and right with fresh curiosity!

Fang Ye patted a wooden shelf beside him and introduced with a smile: "This is the Wind Valley Machine!"

After the rice is dried, the millet is blown through a wind grain machine so that the lighter impurities, husks and broken husks are blown out, and the plump rice is left behind and loaded into the warehouse.

The principle you should have talked about in junior high school physics class, f=ma.

Very ancient traditional tools, there were in the Western Han Dynasty, and "Heavenly Creation" is also recorded.

There are still many rural areas that are still in use, and I have to admire the wisdom of the ancients. ”

Qian Keke said: "It looks a bit like a barbecue grill!" ”

Both are rectangular and have a rocker blower vent.

Tang Xiaoxin has a different opinion: "I feel like a steam locomotive!" ”

Fang Ye demonstrated, took a little rice and poured it into the funnel above, took the bamboo basket below, and then began to shake the handle of the windmill with his hand.

The wind valley machine sounded "woo~woo~woo~"!

The plump grains flowed down from the outlet below, caught by the bamboo basket, and impurities flew out from the other side.

After shaking it a few times, let the children come up and experience it in turn, and everyone had a lot of fun!

Fang Ye left, Qian Keke was still shaking the handle with great interest, while Tang Xiaoxin stretched his face to the air outlet, closed his eyes and opened his mouth: "Ah......"

Seeing the fans, few people can't resist playing like this.

Qian Keke was quickly treated as a chestnut by Qian's mother: "Let's go, still playing!" ”

Qian Keke covered his head and said aggrievedly: "People are originally very smart, but they were stupid by you like this." ”

Tang Xiaoxin took advantage of Qian's mother's inattention and secretly stuck out her tongue at Qian Keke.

Continuing forward, Fang Ye pointed to a machine very similar to the Wind Valley Machine and introduced: "Now it is common to use a hulling machine to hull rice!" ”

The staff poured half a bag of dried rice into the funnel of the huller.

When the switch was pressed, the belt kept spinning, and the yellow rice flowed down from the outlet.

Some children wondered, "Hey, why is this like this?" ”

The staff explained: "It's only been grinded once, and it's going to be grinded three times!" ”

The second time I grinded, the rice looked a lot whiter, a bit like the rice I usually eat, but it was still faintly dark.

The third time I grinded, what came out was white and crystal rice!

"Oh~"

The children were amazed and applauded.
