Abstract

The potato demonstration field in Kalaqinqi of Inner Mongolia has brought good news of harvest. In 2025, the 'Hundred Counties, Ten Thousand Acres' soil health and yield enhancement initiative was implemented, achieving remarkable results in potato cultivation through the 'functional strains-live bacteria preparation on-site-immediate production and application' model.

The potato demonstration field in Kalaqinqi of Inner Mongolia has brought good news of harvest.

In 2025, the 'Hundred Counties, Ten Thousand Acres' soil health and yield enhancement initiative was implemented, achieving remarkable results in potato cultivation through the 'functional strains-live bacteria preparation on-site-immediate production and application' model.

Bacterial cultivation demonstrates remarkable efficacy

Compared with the control area, the yield measurement data clearly demonstrate the comprehensive benefits of technology application.

Karaqin Banner - Potato Live Bacteria Planting Effect
Category	Compared with the control area, the efficiency indicators of the demonstration area are as follows
Fertilizer reduction	7.69%
Pesticide reduction	50%
Save on input costs	135 yuan
Increase yield per mu	1614.1 kg
Yield increase	34.7%
Increase income per mu	807.05 yuan
The income per mu increased	942.05 yuan

While ensuring healthy crop growth, the demonstration area achieved the 'two reductions': fertilizer application decreased by 7.69%, and pesticide usage dropped by 50%.

The most encouraging aspect is the 'two increases': potato yield per mu has achieved a significant leap, with a production growth rate of 34.7%, translating to an additional 1,614.1 kilograms per mu.

The final calculation shows that the increased production alone generated an additional income of 807.05 yuan per mu, while the combined savings in agricultural input costs contributed to a total economic benefit of 942.05 yuan per mu.

Application of live bacteria: Promoting robust growth during the seedling stage

The field observation conducted 18 days after the application of the demonstration using Trichoderma harzianum and Bacillus subtilis live bacteria showed that the potato in the demonstration group had a significant advantage during the vegetative growth stage: the average plant height was 48.9 cm and the stem diameter was 1.25 cm; while the conventional planting control group had an average plant height of 46.1 cm and a stem diameter of 1.12 cm.

The data showed that the treatment of live bacteria effectively promoted the healthy growth of crops in the early stage and laid a good foundation for the later yield formation.

Application of live bacteria: Stress resistance and disaster reduction as the core of yield increase

The significant yield increase demonstrated in this experiment is attributed to the critical role of microbial live bacteria in pest control under extreme climatic conditions.

During the planting season, the control area was flooded by heavy rainfall, leading to the outbreak and spread of soil-borne diseases, with some plants even suffering total crop failure.

The demonstration area regularly applies green nitrogen and live bacteria to continuously enhance the content of beneficial microorganisms in the soil, significantly improving the stress resistance of potato roots, thereby substantially reducing the occurrence and damage of diseases.

In the control plots where additional pesticides were applied due to disease risk, the demonstration area reduced the first pesticide application by leveraging the pre-protective effect of green nitrogen live bacteria. With improved soil fertility and root vitality, the demonstration area also decreased the top-dressing fertilizer application by 10 kg.

Small cases reflect the big industry: China's potatoes urgently need to improve quality and efficiency

Karaqin Banner is located in the golden planting belt of 41° north latitude, with an annual planting scale of more than 50,000 mu, and the practice in 2025 is a microcosm of China's potato industry seeking green transformation.

As the world's largest potato producer and consumer, in recent years, China's potato sown area has stabilized at about 70 million mu, with an output of nearly 90 million tons, accounting for about a quarter of the world, and the output has ranked first in the world for many years.

However, there are also challenges behind the industrial boom:

The average yield of potatoes in China is about 1.3 tons/mu, which is more than 2.5 tons compared with the yield of more than 2.5 tons in developed countries in Europe and the United States.

However, the long-standing problems such as single variety structure and soil degradation and soil-borne diseases caused by heavy stubble planting (with an average annual occurrence of more than 6.5 million mu) seriously restrict the sustainable development of the industry and the further growth of farmers' income.

The development of China's potato industry is facing challenges
The product structure is unreasonable	Some areas are overly dependent on traditional varieties, aging varieties, low market value, and difficult sales; The proportion of special potatoes and high value-added varieties is low and cannot meet market needs
The fertilizer used for planting is not scientific	Single fertilization and heavy stubble planting lead to an imbalance in soil microbial community, which in turn leads to problems such as soil compaction, insufficient fertilizer utilization and continuous cropping obstacles, and finally leads to frequent soil-borne diseases
Disease prevention and control pressure is high	Soil-borne diseases such as anthrax and scab occur in an average annual area of more than 6.5 million mu, especially in the northern production areas, which directly threaten yield and commerciality
Shortcomings in the industrial chain	The deep processing capacity is insufficient, the added value needs to be improved, and the market competitiveness still needs to be strengthened

Innovative practice: live bacteria technology to break the barrier of continuous cropping

Through the green nitrogen live bacteria technology introduced in this "100 counties and 100,000 acres" action, it directly targets the pain points in potato planting:

This technology reconstructs a healthy soil microecology by supplementing functional live bacteria, thereby improving fertilizer utilization, inhibiting soil-borne diseases, breaking down continuous cropping barriers, and more importantly, by enhancing the health and resistance of crops under extreme or adversity conditions, it realizes the disaster prevention and mitigation function of "ensuring yield and stable yield".

The results of this yield measurement not only verify the feasibility of this path, but also provide a set of verifiable and quantifiable green and high-yield technical solutions for solving the soil and disease problems commonly faced by China's main potato producing areas, coping with increasingly changeable climate challenges, and developing resilient agriculture.

Green Nitrogen Biotech assistance Launches 'Hundred Counties, Ten Thousand Acres' Initiative! On-site Fermentation Technology Activates Farmland Potential, Inviting Counties Nationwide to Jointly Build Green Farmland

Currently, China's crop productivity growth faces constraints due to soil degradation, monoculture barriers, excessive reliance on chemical fertilizers and pesticides, and water scarcity. On March 16,2025, the research team of the National Key R&D Program "Synergistic Technologies and Demonstration for Soil Health Maintenance and Productivity Enhancement in Medium-Low Yield Fields in Northern Arid Regions" launched the "Demonstration Initiative for Soil Health and Yield Improvement in 100 Counties and 10,000 Hectares" in Beijing. Centered on microbial technology, the project aims to establish 10,000 hectares of demonstration fields across 100 counties within two years, promoting green agricultural development and exploring a win-win path for ecological and economic benefits.
