Chapter 0156 - Loess Plateau!

He looked at the 3D virtual image of the soybean again, and the changes in the entire root system were visible to the naked eye, and the main branches of some lateral roots were comparable to the thickness of the taproot.

Chen Cheng hurriedly implanted the rhizobia into it, and then watched the simulation process.

Sure enough, this time the rhizobia was able to stay on the lateral roots and form nodules.

Chen Cheng found that the lateral roots of soybean do not penetrate deep into the soil like the taproot, but are a few centimeters below the surface of the soil, which is more suitable for the reproduction and development of rhizobia.

The simulated results showed that the nitrogen fixation function of rhizobia was increased by 241%!

Such a perverted nitrogen fixation effect leads to the fact that the entire soybean plant grows wildly due to overnutrition.

In the end, soybean production increased by only 78%.

Chen Cheng was not very satisfied with this effect.

The reason is that this increase is only an increase per soybean plant, but due to the exponential increase in the lateral root area, the number of soybeans planted per unit area has also doubled.

That is, because of the increase in lateral roots, 2,000 soybeans can be planted per mu, but now only 1,000 soybeans can be planted.

In this way, the 78% increase in soybean production is not good, but rather a loss.

Chen Cheng calculated that the increase in soybean production must reach at least 100% before it can be considered balanced.

Today's soybean plants have thicker rhizomes and more lush foliage, but most of the nutrients are used for growth and do not accumulate in the soybean fruit.

The next step is to inhibit plant growth and promote the accumulation of nutrients in the soybean fruit.

When Chen Cheng was about to start the experiment, the phone rang.

"For, Expert Xiao Chen, I'm Wu Bin."

"Minister Wu?" Chen Cheng was surprised why he called him.

"Xiao Chen, we've already found out. The Ministry of Commerce called me today, saying that they have clarified the changes in international soybean prices through various channels. ”

"What the hell is going on?"

"Because a scientist in Chouguo has developed soybean fuel technology, which has passed verification experiments, it is estimated that this technology will soon be introduced to the market."

"Soy fuel technology?" Chen Cheng asked.

"Yes. The use of soybean oil extraction as fuel power has been researched for a long time, and the current mainstream is soybean oil decomposition technology and soybean oil blending technology. ”

Soybean oil decomposition technology uses a catalyst to crack polymer soybean oil into small molecule hydrocarbons to meet complete combustion.

"The Sword Comes"

Fuel blending is the mixing of soybean oil with other flammable fuels to achieve the possibility of full combustion.

Because of the complexity of this technology, it is still in the research stage at home and abroad.

But soybean oil as a fuel technology is a technology that many people are looking forward to.

After all, soybeans are a renewable resource and are more futuristic than fossil fuels, which are used in smaller and smaller quantities.

"Now that this technology is in place, shouldn't the Big Four promote the widespread cultivation of soybeans around the world? After all, the more soybeans they produce, the more soybeans they can trade. Chen Cheng asked.

"No, this time they don't want to make money on soybeans, they want to make money on oil."

Wu Bin said: "Regardless of whether this soybean fuel technology is true or not, it has now caused a chain reaction in the ugly country market." Many oil companies have slowed down the progress of oil reserves, which is quite interesting.

And they want to use the soybean stocks in their hands to reverse the oil market price through various price rises and falls. ”

Chen Cheng roughly understood.

"In other words, the four major grain merchants are now depressing the market price, deliberately making farmers around the world unwilling to plant soybeans, and then waiting until later to use their storage to control soybean prices?"

"That's pretty much it." Wu Bin said.

"So what's our response?" Chen Cheng asked.

"It doesn't matter how they operate the market. What we need to do is to expand soybean production, at least to ensure that domestic soybean demand is replenished, and at least not to overburden soybean processors and consumers. ”

"Okay." Chen Cheng said.

"How's your side doing?" Wu Bin asked.

Chen Cheng clasped his head and said: "I have experimented with a soybean variety that can increase the area of lateral roots, and the yield has increased a little, but this will greatly reduce the number of units planted."

So, it's not too successful yet. ”

"Increase the lateral root area?"

Wu Bin repeated two sentences, and then asked: "In other words, the soybean root system has become very developed?" ”

"Yes. However, the decline in the number of plantings per unit area has led to a lack of significant increase in yields. Chen Cheng said with some disappointment.

"Have you experimented with the drought resistance of this variety?" Wu Bin asked.

"Not yet, what's wrong with that?"

Wu Bin said: "If you can resist drought, maybe your soybean with a well-developed root system will play a major role!" ”

"What do you mean?" Chen Cheng was a little incomprehensible.

"The Loess Plateau is vast, but it is not available arable land in our country."

Hearing Wu Bin say this, Chen Cheng instantly came to his senses.

"That's right! If soybeans with well-developed roots can be grown on the Loess Plateau, it will be a lot of money! ”

Soybean production increased, land improvement, vegetation greening.

These three benefits are far more beneficial than an ordinary soybean variety with increased yields.

The total area of the Loess Plateau is more than 600 million mu. Loess particles are fine, the soil is soft, rich in mineral nutrients, except for a few stony mountains, the thickness of loess is between 50~80 meters, and the thickest is up to 150~180 meters.

In terms of soil quality alone, the Loess Plateau is suitable for farming.

But the real situation is that the Loess Plateau has few flat land, many slopes, and broken ground. The loess structure is loose, porous and vertically fractured, and many substances are easily soluble in water. As a result, the water content of the land is so low that it cannot hold water at all.

However, the precipitation on the Loess Plateau is mainly concentrated in July and August, and there are many heavy rainfalls. As soon as the flood was rushed, all the sediment flowed into the Yellow River.

In addition, the Loess Plateau is an earthquake-prone area, the plateau ground is broken, the valleys are vertical and horizontal, and the valley slopes are steep, and the loess slope is easy to lose its balance during the earthquake, and a large area of landslides occurs, which makes the slope more broken and the erosion of flowing water is further aggravated.

Rainwater, runoff and wind directly erode the loess surface, which will inevitably cause serious soil erosion, flood and drought disasters become more and more frequent, and agricultural production will fall into a vicious circle.

In fact, a long, long time ago, the Loess Plateau was a forest and forest-steppe zone, due to the long-term irrational use of land resources in history, long-term human activities, reclamation of steep slopes, destruction of trees, overgrazing and wood mining, and abuse of land.

The increasing area of reclamation will inevitably lead to an increase in soil erosion. The already scarce vegetation of the Loess Heights is still being cut down for firewood. Irrational land use has led to the intensification of soil erosion, which has caused the forests and grasslands to gradually disappear, and become today's barren mountains and bald mountains.

Chen Cheng didn't even dare to imagine what kind of beautiful scene it would be if this variety of soybeans could grow on the Loess Plateau.
