The rise of nanometers

Chapter 427 Water and Fish

The wind in October is very noisy.

Li Tanwen was busy in the fields for more than an hour. It was approaching 12 noon, and the scorching sun hanging above his head made the sand feel hot.

The Xiaonanhu 006 farm where he works has not yet been fully renovated, and more than a dozen colleagues are installing other infrastructure.

For example, he is responsible for the spray pipe network, power generation black layer, monitoring system, etc.

The power generation black layer system is the most important. It adopts a rollable composite solar power generation film, which can block a large part of the sunlight from directly exposing the soil. It can not only generate electricity but also reduce the evaporation of soil water.

In the early stages of planting and during the rest period, the solar film can be put out; when the crops enter the rapid growth period, the solar film can be rolled up.

In addition, in winter, it can be used as a greenhouse. Through solar power generation and a power station that stores carbon powder, the carbon powder stored in the summer is converted into electrical energy. Full fluorescent lamps and natural light are used to make the interior of the greenhouse become A suitable environment for farming.

Looking down from above, these grid-like farms look like they are wearing striped shirts, because the solar film is not completely covered, but is distributed in stripes, leaving rows of gaps.

These gaps can be covered with high-strength transparent films in winter and used together with solar films to form a greenhouse.

In this mode, photovoltaic and wind power combined with carbon powder make the farm self-sufficient in electricity, and even generate some surplus electricity every year.

As for the issue of water charges, although the initial transportation costs are very high, reaching an average of about 8.7 yuan per cubic meter, this price is not static.

A large part of the cost of water transmission is the shared cost of pipelines and infrastructure, and this part will become less and less over time.

Another big factor is electricity, which is also the main part of current transportation costs.

After all, water is transported from the eastern coastal area to the west five to six thousand kilometers away. Due to the influence of the terrain, pressurization stations must be installed at regular intervals.

Even if the pressurizing stations along the way have kinetic energy recovery systems, the electricity bill is still very high.

However, the cost of this part cannot be reduced. Suiren is equipped with a large number of solar panels, wind power and kinetic energy recovery, and emergency gas power stations along the route.

As time goes by, the water transportation cost of the East-to-West Water Transmission Project will decrease year by year, with an average annual decrease of about 15%.

Including official subsidies, it is expected that the cost of fresh water imported into Xinjiang will drop to about 0.8 yuan per cubic meter around 2020.

Once this water enters the territory, it will not disappear completely after irrigation and use. A large part of the water will be evaporated into the atmosphere, and some will seep into the ground.

When the local microclimate changes, a virtuous cycle will gradually form, causing fundamental changes in the agriculturally usable area in the region.

For example, the gravel desert in the Hami region (i.e. the Gobi Desert) has a high proportion that can be transformed into farmland and pasture.

There are also the Gurbantunggut Desert in the Junggar Basin and the Kumtag Desert near Lop Nur. These areas can all be transformed.

Although the Taklimakan Desert, which is densely covered with moving sand dunes, does not meet the conditions for complete transformation, at least half of the area along the ancient river channel can be transformed into an agricultural area.

Including the Kongque River, Tarim River, Yarkand River, Hotan River, Kriya River, and Chelchen River. The areas along these rivers were originally oases and grasslands in ancient times and had innate conditions for transformation.

After completing these transformations, the agricultural utilization area of ​​the entire Xinjiang will increase by 367,000 square kilometers, and the area of ​​desert and Gobi Desert will shrink to 220,000 square kilometers.

It is equivalent to increasing the area of ​​two Hebei provinces.

Although only 280,000 square kilometers of the 367,000 square kilometers will be used as farms, pastures and forest farms, and the remaining 87,000 square kilometers will be used as nature reserves.

280,000 square kilometers is 420 million acres, which is almost a quarter of the national red line of cultivated land of 1.8 billion acres.

Including the reconstructed areas in Mongolia, Gan, Ningxia and Dongbei provinces, the domestic agricultural usable area will increase by 900,000 to 950,000 square kilometers around 2020, or 1.35 billion to 1.425 billion acres.

In addition to the transformed saline-alkali land, the desert Gobi Desert and saline-alkali land in Mobei.

It is estimated that around 2020, 2.6 billion to 2.7 billion acres of agriculturally usable land will be available.

By then, the Grain Alliance will have become an important producer of agricultural products in the world. So what about ABCD? In the face of absolute power, ABCD will also kneel down.

What's more, the agricultural technology of the Food Alliance is improving very quickly, and breeding optimization, fertilizers and pesticides, agricultural machinery and equipment, soil improvement, etc. are all advancing by leaps and bounds.

In the first three quarters of this year alone, the Grain Alliance’s investment in agricultural technology reached 134.9 billion yuan, and the annual investment is expected to exceed 170 billion yuan.

The huge investment has brought about a lot of technological achievements. For example, the Fangge comprehensive farm now in use can still achieve year-round farming even if it is located near 40 degrees north latitude.

Li Tanwen and a dozen people came to the Fangge Comprehensive Farm next door. This farm has been basically renovated and currently has a large area of ​​alfalfa planted.

In the farm's staff canteen, everyone is queuing up for meals.

Li Tanwen ordered a pan-fried rainbow trout, a hand-shredded cabbage, a large plate of chicken, an asparagus, and a bowl of carrot, corn and pork ribs soup.

"Awen, this way."

He sat next to some colleagues with whom he had good relationships.

From the floor-to-ceiling windows on the second floor, you can see the endless sea of ​​sand.

"Why is this fish today such a foreign thing?" A colleague picked up a piece of rainbow trout and complained.

Another colleague shook his head: "This is not salmon, but rainbow trout. I heard it was raised in Dunhuang."

"Dunhuang? There was quite a big fuss about that incident last month. What's going on behind the Yangguan Forest Farm?"

"What else? A few have gone in."

Li Tanwen asked in confusion: "It seems that our company has also invested in planting Dunhuang vineyards!"

An old employee who knew some inside information whispered: "Our company's water is self-sufficient and has nothing to do with us. There are also many local vineyards that have been affected, mainly because Yangguan is too greedy. Don’t beat everyone to death with one stick.”

“What about this rainbow trout farm?”

"Don't worry, there is more than one rainbow trout farmer in Dunhuang, and several of them are our company's cooperative companies. It's not like you don't know about our company's cooperative companies," the old employee explained with a smile.

Many people nodded to this. The Suiren Department has very high requirements for cooperative companies. If there are any problems, they will have been kicked out long ago.

Rainbow trout and sturgeon have developed into pillar industries in Dunhuang, and there are currently more than a dozen breeding enterprises.

Domestic restaurants like to use rainbow trout as salmon, but rainbow trout cultured in fresh water itself contains many parasites.

However, in May this year, Fengmin Agriculture developed a special insecticide technology that can remove 99.99% of parasites and eggs in rainbow trout.

This technology is actually an improved version of the gold nanorod-photothermal knife, which uses cheap iron nanorods to kill parasites quickly and efficiently.

However, this technology can only be used for food pest control for the time being, because this technology will directly kill rainbow trout.

The main reason is that the infrared absorption frequency band of iron nanorods overlaps with the iron in hemoglobin. While killing parasites, it will also destroy part of the hemoglobin.

After being exposed to infrared light, rainbow trout will die after being exposed to infrared light for only a day or two.

Therefore, before the rainbow trout leaves the factory for sale, they are fed iron nanorod feed and undergo infrared pest control.

But for people who like to eat fish raw, this technology is simply good news.
