After a while, the children had almost harvested.

Fang Ye looked at the rice field, blew a whistle and clapped his hands: "well, let''s tidy up the rice cut here and have a rest! Those who want to thresh grain can have a try and take you to dry the grain later."

A child quickly raised his hand and said, "mine hasn''t been cut yet!"

Fang ye said with a smile, "there''s not much left. Let''s save some for the birds!

Although we grow the field, we also rely on all kinds of organisms in the field for the healthy growth of rice.

Take it from nature and give it back. "

Some children are not willing: "ah ~ ~ isn''t this a waste of food!"

After all, it''s the rice you planted hard. After transplanting the seedlings, your back is sore and your legs and stomach still hurt for several days!

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

There are about 6500 Oriental white storks in China. Last winter, enough 5000 moved to Tianjin for the winter.

There have never been so many in previous years because they can''t get enough food through several wetlands along their migration route.

When these Oriental White Storks get together, they can easily become targets of poachers. Frequent ups and downs may also hit high-voltage lines and be electrocuted.

Without enough food, they could only eat the fish in the villagers'' fish pond, which was driven away by the villagers with firecrackers. Finally, volunteers raised money to buy them fish and build a canteen, which temporarily solved the crisis.

Because of the impact of human activities, many wetlands have disappeared or are being destroyed.

Among the threats faced by wetlands, in addition to reclamation and reconstruction of farmland around the lake, dredging ships excavate a large amount of river sand in the riverbed and lake bank.

China''s large-scale urbanization in the past few decades has a great demand for sand. Sand is used in glass, concrete and building materials, and the most ideal sand for industry comes from rivers and lakes rather than the sea.

The paddy field is equivalent to a small wetland, which can make birds tired, stop to rest and replenish.

As our human community develops, don''t forget to leave some living space for these wildlife neighbors.

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

"Oh!"

After listening to what Fang ye said, the children blinked twice and looked like they were going to cry: "can you save more for them?"

Fang Ye squatted down and touched the child''s head and said gently, "OK, the bird who comes here to rest will certainly thank you ~"

Some parents lamented: "in the past, when we harvested in our hometown, we deliberately left some wheat, corn and sweet potato, just to leave some food for overwintering animals."

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

"Ah, our hometown used to hate migrating wild geese very much, because they could eat wheat and exchange foreign exchange. Many of them were knocked out. Later, they didn''t dare to settle down with us... Now if they have the opportunity, they will be better for them."

"While developing our human community, don''t forget to leave some living space for wildlife neighbors. That''s very good!"

Not only the children, but also the parents listening on the ridge feel that they have learned a lot!

I have always had the impression that the zoo is a place for entertainment and relaxation. I look at elephants and pandas and feed two pieces of meat to tigers.

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

The zoo made some fields to let the children 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 harmonious coexistence between man and nature.

The harvest far exceeded expectations.

After the children experienced threshing, fangye called the breeder of the small farm and took a bag to pack the threshed millet.

Take away the rest and let the machine handle it.

"Come on, let''s clean up the rice straw! The rice straw after threshing is also very useful. It can not only be fed to alpaca, but also be used as a straw mat for animals to sleep after drying, but also be fermented with feces and turned into fertilizer!"

Fang ye put the unfinished rice in a small cart, waved his hand and said smartly, "gogogo! Deal with these first."

There is a small brick house behind the small farm.

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

This is the rice processing room, where all kinds of machines are placed. It is also the storage room for farmland tools at ordinary times.

Fang Ye greeted the children and said, "everyone follow me in an orderly way. Keep a distance. Don''t touch it! Parents also help watch!"

After the children came in, they all looked around freshly and curiously!

Fang Ye patted a wooden shelf around him, smiled and said, "this is a wind Valley machine!

After the rice is dried in the sun, the fan will be used to blow the rice again, so that the lighter impurities, husks and broken shells will be blown out, and the full rice will be left and loaded into the warehouse.

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

Very ancient and traditional tools existed in the Western Han Dynasty, and it is also recorded in Tiangong Kaiwu.

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

"It looks a bit like a barbecue oven," said Qian Keke

They are all rectangular and have a handle blower.

Tang Xiaoxin had different opinions: "I feel like a steam locomotive!"

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

The valley blower "woo ~ woo ~ woo ~" rang!

The full grain flowed down from the outlet below, was caught by the bamboo basket, and the impurities flew out from the other side.

Shook a few times and let the children come up and experience it in turns. Everyone had a good time!

When Fang Ye left, Qian Keke shook the handle excitedly and kept turning. Tang Xiaoxin stretched her face to the air outlet, closed her eyes and opened her mouth: "ah..."

Seeing the fan, few people can resist playing like this.

Qian Keke was soon led by Qian''s mother: "go and play!"

Qian Keke covered his head and said wrongly, "people were very smart, but they were knocked silly by you."

Tang Xiaoxin secretly spit out his tongue at Qian Keke while Qian''s mother is not paying attention.

Moving on, Fang Ye pointed to a machine very similar to the fan and said, "now we usually use the sheller to shell the rice!"

The staff poured half a bag of dried rice into the hopper of the sheller.

Pressing the switch, the belt kept turning, and the yellow rice flowed down from the outlet.

A child wondered, "Hey, how is this?"

The staff explained, "it''s only been ground once. It''s going to be ground three times!"

After the second grinding, the rice looked a lot white, a little like the rice we usually eat, but it was still faint and dark.

After the third grinding, the white and glittering rice comes out!

"Oh ~"

The children were amazed and clapped their hands.
