Chapter 304 300. Go get some free stuff!

Cause: Luo Yihang contracted a thousand acres of land and came to Professor Du to change the plan.

Process: We talked a lot about breeding, but didn’t talk much about planning.

Turning point: Dr. Wei got something good, and Professor Du also wants to get some good stuff.

Result: The next day, direct flight to Shenyang.

Go and get some free stuff!

They are still fleecing the Academy of Sciences.

The year was 1988.

We once launched the "Huanghuaihai" agricultural science and technology campaign.

In the six years from 1988 to 1993, 67 major scientific and technological achievements were made, 2 of which won the National Science and Technology Progress Award. Among them, 16 reached international standards and 12 filled domestic gaps.

At that time, they were known as the two bombs and one satellite of agriculture.

In 2017, the second agricultural technology campaign began in Northeast China.

It’s called the “Black Soil Granary” Agricultural Technology Campaign.

Moreover, this technological battle will last longer than the "Huanghuaihai" period and is planned to continue until 2030.

Now is the time to conclude the first phase and accept the results.

Because modern agriculture is interdisciplinary, it is not just a matter of agronomy.

Therefore, both scientific and technological campaigns were led by the Chinese Academy of Sciences.

Therefore, the wool being fleeced is also being fleeced from the Chinese Academy of Sciences.

After Professor Du and Luo Yihang arrived in Shenyang, they drove north.

The place we went to was called the "Black Soil Granary" Agricultural Science and Technology Battle Shenyang Demonstration Zone, and Dr. Wei was also here.

After arriving at the demonstration area, we first took a tour and received an introduction.

Only then did Luo Yihang have a perceptual understanding of this operation code-named "Battle".

too exaggerated!

The core demonstration area is 11 mu, and the demonstration and promotion area is 7700 million mu, spanning three provinces.

The unit is ten thousand acres.

There are now 22 main projects and countless experimental projects.

Not to mention the people involved, it's exaggerated and scary.

Experts who are treasured in other places are everywhere here.

For example, Luo Yihang visited a non-promoted project, smart agricultural machinery.

There are four academicians in charge of the project.

Professor Du, who is in his sixties, was a junior when he came here, but he actually enjoyed the care from his elders.

I was called "Xiao Du is here" and "How are you, Xiao Du?"

That's interesting.

Luo Yihang also followed suit, saying, "The kid is pretty good.", "The kid is enterprising, very good."

The campaign has already achieved results. The grain output in Northeast China has nearly doubled, and the proportion of grain output in the country's total grain output has increased from 2% to 12.74%. The increase in grain accounts for 25.36% of the country's total grain output increase.

It's been less than five years.

Nearly ten years will pass in the future...
-
Luo Yihang and his team stayed in the Shenyang Demonstration Zone for four days, mainly waiting for Professor Wei's approval. It turned out that the agricultural active phased array radar and the matching drone warning and identification system were also a project of this battle.

After completion, the group moved to the Changchun Demonstration Area and stayed there for another three days.

Professor Du’s knowledge may not be at the forefront, and his students have already practiced and it depends on each individual, but he is definitely the owner of the face fruit.

This week, I took Luo Yihang around and often I could go on a visit just by making a phone call.

Luo Yihang really opened his eyes.

I saw a lot of new things.

For example, there is a small drone with a laser cannon.

It is a smaller version of the drones used by power departments to remove objects from high-voltage power lines.

Can fly to the sky and pick fruits.

I heard from the explanation that in order to make picking easier, fruit trees are nowadays cultivated to be dwarfed as much as possible.

In fact, fruit trees can grow very tall. An apple tree that is more than ten meters tall can definitely bear more fruit in the same area as an apple tree that is only one or two meters tall.

Besides, there are still many fruit varieties that have not been dwarfed.

There are also high-quality varieties that have to be abandoned because they cannot be dwarfed.

If the efficiency of this kind of drone is comparable to that of manual labor, then there is no need to prioritize dwarfing of fruit tree varieties, and the conditions will be much more relaxed. If it can be equipped with automatic control, automatic identification, infrared cameras, etc., maybe you can put up a net under the tree, turn on the drone, pull up the battery box to charge automatically, and let it pick the fruits by itself.

The fruit farmers go home to sleep and come back to harvest in the morning when they wake up.

Cyber ​​serfs belong.

My cousins ​​from Guangxi no longer have to swing the scissors until smoke rises when they cut tangerines.

But unfortunately, it has only reached the point where it can biubiubiu. The functions of intelligently controlling the laser intensity and finding the fruits inside the leaves are still in progress. It is unknown how long it will take to be fully realized.

By the way, I unexpectedly met Engineer Yang in the Changchun Demonstration Area.

After leaving Luo Yihang, Engineer Yang came to Changchun. In fact, this is their main battlefield.

The smart agricultural system also participated in the "Black Soil Granary" agricultural technology campaign.

So, Luo Yihang has already achieved some results in the battle.

There were so many good things that Luo Yihang was dazzled and wanted every one of them.

"Stop, stop. Not everything can be used by you. You have to base it on the current situation where you are. See what is most needed."

"Your biggest problem now is that you have an extra thousand acres of land, but it has been abandoned for more than ten years. After it is reclaimed, the land needs to be maintained."

"Besides, you don't have enough manpower. With your few dozen people, you can't farm a thousand acres of land. You can't even do daily maintenance."

"And what is your core? It's the soil microbiome, and everything else has to revolve around that. Spreading the microbiome is the primary goal."

Then.

Professor Du used his reputation to get the first chance to go to the Key Laboratory of Soybean Molecular Design and Breeding of the Chinese Academy of Sciences.

They have developed 31 soybean varieties in the "Dongsheng" series.

The fat content of "Dongsheng 79" is 24.16%, setting a new record for high-fat varieties in Heilongjiang Province in the past 50 years.

"Dongsheng 118" achieved a breakthrough of 149 kilograms per mu in medium to severe soda saline-alkali land.

There are also "Dongsheng 17, 19, 37, 77" and so on that focus on high yield.

The entire Dongsheng series is one of the 22 main projects promoted in this Black Soil Granary Battle.

Leguminous plants, especially soybeans, grow rhizobia that can fix nitrogen.

What Professor Du was fleecing was not Dongsheng soybeans, but Dongsheng’s paternal variety.

The Dongsheng series is a hybrid soybean, and its paternal line is an unlimited-pod variety.

It is characterized by tall plants, long internodes, scattered pods, and only two small pods at the top, or even no pods.

Its value lies mainly in its flowers, which are used to pollinate other varieties and hybridize into the Dongsheng series of soybeans.

It's just right.

The ability to fix nitrogen and nourish the soil is not a consideration, as the output won't be much anyway.

Soybean straw is tall and contains a lot of organic matter. It can be used to make mushroom bags and can be fed to pigs after fermentation.

Of course it is better to feed cattle and sheep.

The cycle of feces - earthworms - earthworm soil - microbial flora is continued.

These two items alone will pay for themselves.

Another source of income is from selling flowers, or more precisely, pollen.

Only then did Luo Yihang realize that pollen could be sold.

There is even a special term for it, called off-site application of soybean pollen.

very important.

Because of hybrid varieties, there is often the problem of different flowering periods between the male and female parents.

Also, the male and female plants have different growth requirements and cannot be planted together.

Artificial pollination is required.

The demand for the Dongsheng series is huge, so the pollen can be sold at a high price and the soybean laboratory can recycle it.

Pollen cryopreservation technology is also provided for this purpose.

Signed a unified purchasing contract.

The laboratory provides 500 acres of bean seeds.

It didn’t say what variety it was, nor did it say which model of Dongsheng it was suitable for.

Even when introducing it, they didn't tell us whether it was because Dongsheng had a different flowering period or because its parents adapted to different environments.

This is called confidentiality awareness.

Hey, learn another trick.
