Mankind's quest to increase production is never-ending.

Qi Zheng hurriedly returned to China because, he did not reveal to Vasily that there was another big killer weapon for the increase in soybean production in Jiagu.

The Mercedes-Benz car went all the way, directly through the Sino-Russian border into the territory of Hei Province, and drove straight to the city of Hyrum.

Chen Jianzhang, the person in charge of the Jiagu laboratory, waited there with a smile on his face.

"Old Chen, have the soybeans started to be harvested?" Qi Zheng asked as soon as he got out of the car.

"It's harvesting, it's waiting for you. Chen Jianzhang said with a smile.

The two walked to the edge of the bean field, and saw that on the vast plain, as far as the eye could see, soybeans were planted almost everywhere. In the distance, the vast and lush "sea of soybeans" and the clear blue sky are divided by the horizon, and the soybeans that are more than half a person tall churn the yellow waves, indicating that this year's harvest is likely to be excellent.

In the farm, in addition to Qi Zheng and Chen Jianzhang, there are also a large number of "outsiders" - the leading group of Hailun City, senior officials of Hei Province, and academicians of the Chinese Academy of Sciences...... After greeting them one by one, Qi Zhengyi turned his gaze to the soybean field being harvested, as did the others.

A large combine harvester roared forward, and the soybeans were harvested in a blink of an eye, and the cutting, conveying, threshing, and cleaning operations were completed at one time; on the other hand, the staff were busy weighing the soybeans and measuring the yield on the spot.

As the harvest came to an end, the atmosphere became more and more enthusiastic.

In the middle of the night, Chen Jianzhang could not suppress his excitement and waved the record in his hand and announced loudly: "The new high-yield, high-oil soybean strain 'Jiadou No. 13' we developed has successfully reached 425 kilograms per mu in a large area!"

With a "whoosh", everyone present had ecstatic expressions on their faces.

Qi Zheng also clenched his fists!

This result has set a new record for soybean yield in China!

That's not the point, the point is that this high-yield record is based on 30,000 acres of planting.

Over the years, agricultural researchers have developed many high-yielding soybean varieties, and the yield record has been repeatedly broken.

But if you look closely, you can find that it is a small area to create a high yield record, a large area of demonstration mu production capacity of 200 ~ 250 kilograms, can make researchers shout long live.

It can be said that Jiagu's large-scale demonstration yield per mu is excessively strong even when compared with the best small-area results in China.

This polarization, like the gap between the rich and the poor, is the gap between the rich and the poor who cannot imagine how rich they are.

For a while, the agricultural experts present couldn't help but surround Chen Jianzhang and asked to see the records in person, and the chaotic discussion was chaotic enough.

Among them, an octogenarian with half-gray hair did not step forward to join in the fun, she looked at the harvested soybeans with red eyes, and even spoke with a trill: "The appearance of 'Jiadou No. 13' is really of great significance!"

Qi Zheng reacted, cautiously supported the old academician, and said respectfully: "Academician Chen, thank you too! Without your contribution, the birth of 'Jiadou No. 13' would not have been possible." ”

Although Academician Chen is more than eighty years old, she is still quick thinking, and she said with a smile: "Xiao Qi, we don't make a fool of ourselves, this is what you have done well!"

Qi Zheng shook his head and didn't say much.

For the old academician in front of him, he did not hesitate to pay the highest respect. She can be humble as an old man, but Qi Zheng can't take it seriously because of this.

"Jiadou No. 13" is made by the cooperation of Jiagu Laboratory, the Soybean Research Institute of the Northeast Academy of Agricultural Sciences, and the scientific research team of Academician Chen Lao, using molecular design breeding technology, combined with hybrid and radiation breeding methods, supplemented by soybean rhizobia technology to increase yield, only to reach a yield record of 425 kg per mu.

It can be said that the "Jiadou No. 13" variety alone may yield more than 300 kilograms per mu at the top of the sky, although there are only a handful of high-yielding varieties that can reach this level. However, after supporting the soybean rhizobia technology, the yield per mu has been directly increased by more than 100 kilograms, which is a god-like existence.

The project of using rhizobia technology to increase soybean yield, Jiagu Laboratory started research very early, but the real breakthrough was after Academician Chen joined.

As early as 1988, she discovered the first new genus - the fourth rhizobia genus known in the world at that time, "Chinese rhizobia", which was the first rhizobia genus discovered and named by Chinese scholars.

Over the past decades, Academician Chen Lao has led the scientific research team to excavate and investigate the nodulation of various leguminous plants in 32 provinces, 700 counties and cities, and under different ecological conditions, and collected more than 10,000 plant nodule specimens, of which more than 300 plant nodules have not been recorded; after isolating, purifying and returning to the original host nodulation confirmation, 12,000 strains of rhizobia have been stored and preserved; through the analysis of more than 100 phenotypic traits of 7,000 strains, a number of acid-resistant, alkali-tolerant, salt-tolerant, Valuable rhizobia germplasm resources with strong resistance to high temperature or low temperature......

The best soybean rhizobia strains screened by the Jiagu laboratory are from it.

It is known that rhizobia works because it converts nitrogen in the air into nitrogen-containing compounds for plant use. However, not all rhizobia are suitable for soybean yields.

Even if Qi Zheng has a spiritual array that can promote the transformation efficiency of rhizobia, after the experiment, too much nitrogen can easily lead to a significant increase in the growth of soybean leaves, which in turn affects the soybean yield. It can be said that if there is no rhizobia library of Academician Chen, Jiagu will have to wait until the Year of the Ox to screen the most suitable soybean rhizobia strains.

But in Academician Chen's heart, she didn't think so.

In the early days of the founding of the People's Republic of China, under the organization and leadership of several agricultural microbiology seniors who returned to China, China carried out soybean, peanut and milk vetch rhizobia inoculation experiments extensively, and the results were very good, and the rhizobia inoculation had a prosperous period. However, with the application of a large number of chemical fertilizers, biological nitrogen fixation technology has gradually faded out and is no longer valued.

After devoting herself to rhizobia research, she has traveled all over the green mountains to collect rhizobia and study rhizobia for decades, just to make this invisible microorganism contribute to mankind in the motherland. On more than one occasion, she has made suggestions to the central authorities to strengthen research and popularization in this area.

But her proposal made many people in the industry feel puzzling. They feel that it is too outdated to revisit the "old-fashioned" technology of decades ago?

Jiagu is the first private enterprise in China to invest heavily in rhizobia inoculation technology and apply it to production practice, and Jiagu Laboratory is outrageously strong in microbial cultivation technology!

After screening out the best soybean rhizobia strains, Academician Chen Lao personally watched how the microbial research team of Jiagu Laboratory determined the stable and high-yield fermentation process of the strain step by step, including the optimal fermentation medium formulation, the best fermentation parameters, etc., and screened the appropriate carriers and stable additives step by step, so that the functional strains in the product could survive stably, prolong the shelf life of the product, and reduce the cost......

She felt that even without her own help, Jiagu would be able to succeed sooner or later.

Of course, to make a little contribution to the rise of domestic soybeans, Academician Chen really thinks it's worth it. Because, it is not an exaggeration to say that "Jiadou No. 13" can help Chinese soybeans come back to life.

It is naturally not just Academician Chen who can see this.

When the yield per mu was confirmed, Qi Zheng did not say anything, and the senior officials of Hei Province were ecstatic.

In terms of agricultural development strategy, China's principle of basic self-sufficiency in agricultural products, especially food, is supplemented by international adjustments. However, due to the limitation of cultivated land, soybeans are too dependent on the international market and are too easy to be stuck.

With limited acreage, nothing can revitalize China's soybean industry more than increasing yields.

When he thought that it was already a miracle that Jiagu had increased the yield of most of the soybeans per mu in Hei Province to 200 kilograms through a modern production organization, the "Jiadou No. 13" that doubled the yield per mu was born!

"Promote, promote, must promote......" muttered the high-ranking official of the Black Province who was ecstatic in his heart, as if he were a repeater.

A few seconds later, he immediately rushed to Qi Zheng's side and asked, "Dong Qi, after large-scale promotion, can the yield per mu still stabilize at a similar level?"

Without waiting for Qi Zheng to answer, Academician Chen gave an affirmative answer: "It's not a big problem. The demonstration site in front of us proves that 'Jiadou 13' can give full play to the potential of the variety in large-scale production, and even if there are discrepancies, it will not be less than 400 kilograms......"

Academician Chen has followed the research of "Jiadou 13" all the way, and naturally knows the potential of this variety best.

After receiving the confirmation of Academician Chen, the senior official of Hei Province asked with a smile on his face: "Dong Qi, do you think it will take how long it will take to fully promote 'Jiadou No. 13' in Hei Province?"

If it had been any other time, he would not have asked so bluntly. But the economic benefits of "Jiadou No. 13" are too touching.

It is no exaggeration to say that the economic benefits brought by "Jiadou No. 13" to China's soybean industry cluster will be calculated in hundreds of billions of yuan, and the social benefits are immeasurable. In this sense, Qi Zheng's answer will be a milestone.

The inquiries of the high-ranking officials of the Black Province also attracted others present at once.

If all the 55 million mu of soybeans in Hei Province are replaced with "Jiadou No. 13", even if the yield per mu does not reach the target of 400 kilograms, the output can be directly increased by more than 9 million tons; if all the soybeans in the whole country are replaced with "Jiadou No. 13", there is no need to increase the existing planting area, and China's soybean self-sufficiency rate will rise to 50 percent.

Qi Zheng had thought about this issue earlier than the others, and he was not timid in the eager eyes of the crowd, and he raised a finger and said, "In one year, it can be fully promoted in Hei Province, and in the whole country, it will take at least two years." ”

The high-ranking officials of the Black Province froze.

Academician Chen was stunned.

Everyone froze.

One year, two years, the whole province, the whole country, how dare he think!?

However, it sounds inexplicably emotional.
