China produces 900 million tons of straw every year, and 5.8 billion tons of processing by-products, the average comprehensive utilization rate of these processing by-products is less than 40, and more than 60 by-products are stacked at will, discarded or used as fertilizer and living fuel, which is equivalent to 700 million acres of land input and output and 600 billion yuan of income are lost in vain.

This situation is even more pronounced in the main grain-producing areas.

In the Northeast where Qi Zheng and others are now located, "comprehensive utilization of corn straw" has always been a big problem in Northeast China.

Northeast China is one of the world's three golden corn belts and the country's largest corn producing area, with more than 1.1 billion tons of corn straw collected every year.

However, the total utilization rate of corn straw in Northeast China is less than 50%, and most of the straw is discarded or burned, which wastes a lot of agricultural resources and causes serious haze pollution.

Chen Jianzhang, a political leader of Qi, led a team to come in order to select and breed excellent soybean varieties.

But it is clear that Chen Jianzhang, who came with the latest results of the laboratory, saw a greater opportunity from it.

"We are in the Northeast, we should not limit our eyes to soybeans, the agricultural resources of the Northeast are a great treasure for us, make good use of our advantages, Jiagu will be able to reach a higher level in a few years. Chen Jianzhang's eyes revealed ambition.

Qi Zheng recovered from the surprise brought by the laboratory results and focused his attention on Chen Jianzhang's words.

Looking at Chen Jianzhang's look of "I have a big plan", Qi Zheng almost blurted out a sentence of "please start your performance".

He settled down and motioned for Chen Jianzhang to start "selling" his "big plan".

Chen Jianzhang quickly entered the role and said, "Then I'll start from the beginning." ”

Qi Zheng nodded.

"First of all, back to our domestic soybean support strategy, we have to admit that China's food security is still based on grain production, and the status of soybeans, which are mainly used as oilseeds, has declined. See. Woolen and Chinese networks are in the northeast, as the main grain producing area, the policy orientation will inevitably favor the planting of corn, because the corn yield of the same area is higher than the soybean yield, and farmers are also happy to choose the former. ”

Qi Zheng bowed his head, this cannot be refuted, and the history of the previous life clearly confirms this trend.

"Under the premise that the soybean yield level has not been greatly improved in a short period of time, it is necessary to give full play to the advantages of China's traditional soybean resources, strengthen the research of soybean germplasm resources and the cultivation of new varieties; ”

Chen Jianzhang analyzed that the soybean meal after importing soybean oil can theoretically be used to process various soybean products, but in practice, imported soybeans need to obtain a license from the government, and the use of soybeans must be recorded.

The cost of domestic soybeans in oil extraction is difficult to compete with imported soybeans, since it can't be fight, we have to change our thinking - those who can't see the situation clearly, will only be submerged in the market wave.

For domestic soybeans, although the competitiveness of domestic oil soybeans is weak, but the domestic soybean protein content is high, and it is non-GMO, not only the Chinese people reject GMO, Japan, South Korea and Southeast Asian neighboring countries are more favored by our non-GMO soybeans.

Even in Europe, the United States and other developed countries, people prefer high-priced non-GMO soybean foods and soybean oil.

Therefore, domestic soybeans should further develop green soybean series products on the basis of high nutrition and pure nature, and their international market prospects are broad. Among them, soybean protein is a high-tech product in high-end soybean products, and its processing is also the most potential and promising field in soybean intensive processing, and the market capacity of its products cannot be underestimated. ”

"So now the question is back to the development of green soybeans! How to develop the green soybean industry?"

"These three achievements of the laboratory microbiome have undoubtedly found a breakthrough for us. ”

Speaking of which, Qi Zheng probably followed his train of thought.

Sure enough, Chen Jianzhang's eyes burned, "Let's establish a joint base in the main soybean producing areas in Northeast China!"

"Establish soybean production and processing bases, livestock and poultry breeding bases and crop straw energy bases, plant and produce marketable special soybeans according to the needs of enterprises; digest soybean meal and other healthy feeds in high-quality livestock and poultry breeding concentration areas, and transform soybean enterprise products; ferment and utilize livestock and poultry and idle crop straw in Northeast China to produce biomass energy and organic fertilizer, and feed back green soybean planting ......"

Qi Zheng blinked, looked at the gushing Chen Jianzhang, speechless.

It can only be said that worthy of being the seeds of future academicians of the Academy of Engineering - the group of coercion in the laboratory just made some great things, and their boss directly promoted these things to a strategic position that affects Jiagu and even the entire Northeast, which is simply.

Qi Zheng only focused on the soybean planting base, and at most added a livestock and poultry farm, which was the general layout of Jiagu in the northeast.

Chen Jianzhang's plan is to use straw energy as a link to connect soybean production and processing with livestock and poultry breeding, forming a complete ecological cycle chain that can cover the great northeast.

It doesn't sound like a shock, does it?

But let's only take the most critical straw energy, why is the added value of straw energy the highest?

Looking at its output, biogas plus organic fertilizer, both of which are absolute high value-added products.

So what is the most direct impact on the Northeast?

I dare not say that it is earth-shattering, but it is quite possible to have a new look. At least the sky can return to blue, and the black soil can be more fertile - these two points are precisely the top priorities of the current Northeast agricultural science and technology attack.

After this layout, Jiagu has even evolved from an agricultural enterprise to an energy company, which is AD - a grain company that is most like an oil merchant.

Just by using the idle corn stalks in Northeast China, at least 20 billion cubic meters of biogas can be obtained every year. Whether it is used for gas or power generation, it is a green renewable energy source.

It's not that I couldn't think of it before, but I couldn't do it.

Without the latest results of the laboratory, it is impossible to talk about the most critical straw energy - among which super white rot bacteria and cellulolytic bacteria are the most critical.

The competitiveness of end products (mainly biogas) is the most important constraint affecting the energy utilization of straw gasification, and the competitiveness of products is limited by the efficiency of straw into biogas.

In the process of converting straw into biogas, a variety of non-methanogenic bacteria and methanogenic bacteria are mixed and fermented together to complete four stages: hydrolysis, fermentation, acetic acid and hydrogen production, and methane.

Hydrolysis is the first step and a shackle that currently limits the conversion of straw to biogas.

Straw in its natural state is composed of cellulose, lignin and some proteins. Due to the complexity of the structure of natural lignocellulose, the difficulty in biotransformation lies in how to efficiently degrade it into fermentable sugars.

Previously, there was a lack of highly active strains that completely degraded the natural lignin and cellulose of crop straw.

The emergence of super white rot bacteria and cellulolytic bacteria has broken this shackle, making it possible to accelerate the hydrolysis process of crop straw, and the subsequent fermentation and methane production can also be improved simultaneously, and the input-output benefits are completely different.

But......

How did the soybeans evolve to biomass energy production?

Even Qi Zheng is not mentally prepared for this!
