Within the Jiagu sand control team, there was already laughter.

The large export order of Sanqin beef signed with the Saudis has bathed everyone in the joy of success.

Strictly speaking, this is the first serious income obtained by Jiagu since the development of the desert.

The management of Jiagu's desertification control team, such as Wei Ming, breathed a sigh of relief.

I was under a lot of pressure before!

Although in the eyes of outsiders, it is almost a miracle that millions of acres of barren desert have been transformed into green oases in more than three years.

But from a business point of view, especially in the accounting, it is only in and out for three consecutive years. If you think of the desert development project as a stand-alone company, it is a pauper with huge debts. Although the future is bright, as an investor, there are very few people who can wait with peace of mind.

This is one of the reasons why Jiagu seeks state funding. The governance and development of the Alashan Desert is a semi-public welfare project to a certain extent. As we all know, projects that are generally linked to the word "public welfare" have a worrying return on investment.

Although Qi Zheng and other high-level leaders in Jiagu are willing to wait a few more years to lay a good foundation first. But in the eyes of Wei Ming and others, what the high-level thinks is a matter for the high-level, if they don't want to, the hole is getting bigger and bigger, and there will always be times when there is too much blood loss.

Well, now, I finally see the hope of "blood return".

Just when Wei Ming and the others were about to make persistent efforts, seize the Saudis, a local tyrant, and prepare to sell them more desert output, they were stopped by Qi Zheng.

......

In the middle of the Jiagu Oasis.

Water-saving sprinkler irrigation machines rotate constantly, drawing beautiful circles on the meadow, and patches of alfalfa grow vigorously in the soil-hardened sand.

"Boss, why don't we sell the Saudis potatoes grown in the desert and good wheat? I think they're all interested. Wei Ming, who had followed Qi Zheng to investigate, asked suspiciously.

Qi Zheng didn't answer, but grabbed a handful of sand on the ground, only to see that it was a lump of soil when it was dug up, and unlike before, the sand would drain from between his fingers, and he couldn't help but smile.

"These areas are already suitable soil for growing food?"

When Qi Zheng asked this, Wei Ming couldn't care about his own question, and said proudly: "Yes." And that's just two years after our desert soilization. After testing, it has become completely suitable for growing food crops such as wheat and potatoes. ”

Qi Zheng smiled: "This effect is much faster than we expected. ”

"Not really. Wei Ming laughed out loud, "It's all about the 'evolved' alfalfa!"

Qi Zheng suddenly said: "The root nodules of alfalfa have been successfully improved?"

"That's right!" If it weren't for Qi Zheng having been busy with other affairs since he came to the desert, Wei Ming would have reported the good news to him a long time ago, and he didn't want to report it when Qi Zheng was distracted, just to shout it out loud now.

I only heard Wei Ming say angrily: "The fresh weight of alfalfa grass at the age of 2 can reach about 3,000 kilograms per mu, and the nitrogen content per mu is about 20 kilograms, 3 kilograms of total phosphorus, and 7.8 kilograms of total potassium. 24 kg of nitrogen can be fixed from the air per mu per year, which is equivalent to more than 70 kg of ammonium nitrate. If it is normal cultivated land, alfalfa stubble is enough to stabilize and increase the yield without fertilization for three years, and the yield can even be increased by more than 1 time......"

Since Jiagu Laboratory discovered that there is a subtle "symbiotic phenomenon" between Xintai Sugar No. 22 sugarcane and "Nanzao No. 1" soybeans, which promote each other's growth, they have been running wild in this direction.

However, it is not an exaggeration to say that it is all a matter of luck to find two plants that can form a resonance and have development value.

In this way, the research and improvement of existing crops with "symbiotic phenomena" has become another direction.

Leguminous plants and rhizobia are essentially symbiotic.

Rhizobia is a flagellar-like rod-shaped bacterium that invades the roots of leguminous plants to form nodules. Leguminous crops provide the rhizobia with the necessary energy to break the chemical bonds of inorganic nitrogen, and in return, the rhizobia provide organic nitrogen to the leguminous crops and increase the fertility of the surrounding soil.

Alfalfa is one such leguminous plant.

In the agricultural and animal husbandry map of Jiagu, alfalfa occupies a very important position. As the king of forage, it is not only one of the most important sources of feed for Jiagu agriculture and animal husbandry, but also can improve soil fertility and reduce the fertilizer input of Jiagu agriculture in planting.

Such an important crop, Jiagu laboratory has never stopped researching its improvement. In fact, alfalfa has been modified in the laboratory to show several different evolutionary directions.

For example, salt-tolerant alfalfa varieties are suitable for growing on saline-alkali land, and drought-tolerant alfalfa varieties are suitable for improving soil physicochemical properties in deserts.

"Biological symbiosis is like a 'toolbox' for biological evolution. Alfalfa needs a long time to evolve a root system that is conducive to nutrient absorption, and it is difficult to complete such an evolution even if it is cultivated artificially. But by cultivating super rhizobia and then implanting them in the roots of alfalfa, the alfalfa has completed its evolution. Wei Mingle smacked his lips and said.

Of course, it's that simple, but how to make super rhizobia form a stable symbiotic relationship with alfalfa is cultivated through thousands of experiments in the laboratory. Otherwise, Qi Zheng would not only know about this project, but not know its progress.

Qi Zheng remembered another important question: "Super rhizobia only work on pasture? What about soybeans?"

If the same evolution can be done in soybeans, will it be possible to promote a significant increase in soybean yields?

Wei Ming obviously also understood this, shook his head and said: "It is said that this super rhizobia is not compatible with soybeans, and the super rhizobia for soybeans is still being studied." ”

Qi Zheng nodded thoughtfully, taking this to heart for the time being.

Returning to desert soilization, the "evolved" alfalfa has done a great job.

"Not to mention the fact that the root nodules are much more efficient in fixing nitrogen in the atmosphere, the developed root system is left in the sandy soil layer, which is decomposed to form organic colloids, which can form stable aggregates in the soil and improve the physical and chemical properties of the soil.

Qi Zheng knew that he had overlooked one point.

"Jiukun Liuhe Array (Fourth Order) trigger, main earth system, range: 1,000 kilometers in radius. Effect: Solid soil, fertile ground. It can make the earth solid and fertile. ”

The "Jiukun Liuhe Array" is like a "net" that forms an elastic bond between the grains of sand and organic nutrients. I believe that without this "net", the process of soilization in the oasis would not be so alarming.

Wei Ming spoke with enthusiasm about the 2012 desert development plan: "We plan to plant alfalfa in newly opened desert areas to promote soiling, and to increase the area of wheat and potatoes in oases that have improved soil......

Qi Zheng interrupted him: "I have no problem planting alfalfa in the newly opened desert area, but the planting area of wheat and potatoes should not be increased for the time being, and we should continue to grow pasture." ”

Wei Ming was stunned: "Boss, in this case, even if the yield of forage grass in the newly opened area is not high, it is still millions of acres of alfalfa, can we digest it?"

Qi Zheng rubbed his eyebrows and said, "Well, the situation of overseas forage bases has changed, and we need to increase the supply of local forage. ”
