Big news! Microbial fertilizer welcomes another major opportunity! This "Plan" clearly states!（1）

Today, the National Development and Reform Commission released the "14th Five-Year Plan for Bioeconomic Development" (hereinafter referred to as the "Plan"). What has attracted the attention of the agricultural materials industry is that the "Planning" clarifies the application of biotechnology such as functional microorganisms in soil remediation. This is a re-affirmation of microbial fertilizers at the national level. It is expected that the industry will usher in greater development space in the future.

For a long time, due to the unreasonable application of chemical fertilizers and the widespread use of high-intensity, off-season, and continuous cropping, China's soil conditions are no longer optimistic: poor drought and flood resistance, weak water and fertilizer retention, nutrient imbalance, acidification, compaction, soil-borne diseases The continuous increase and the increase of salt ion concentration have not only affected the income of farmers, but also affected our food safety.

In recent years, action plans for weight loss and efficiency improvement, green development, and zero growth of chemical fertilizers have been introduced frequently, which signifies the government's attention and determination to this green revolution. Whether it is the need for soil remediation or policy orientation, an industry has an opportunity to break out, that is, the microbial fertilizer industry.

The "Planning" proposes to use functional microorganisms, enzymes and other biological technologies to promote the realization of water body denitrification and phosphorus removal, heavy metal soil remediation, solid waste utilization and disposal, promote the improvement of the comprehensive utilization level of straw, and develop pollutant biological environment response monitoring, biodegradation and recycling. Bioremediation, biological resource recycling and other bio-environmental protection industry chains will help to win the battle against air, water, soil and other pollution.

In recent years, microbial fertilizers have become one of the most dynamic sectors of the fertilizer industry with rapid development. Li Jun, director of the Quality Supervision, Inspection and Testing Center for Microbial Fertilizers and Edible Fungi of the Ministry of Agriculture and Rural Affairs, once pointed out that microbial fertilizers are an indispensable input for green (ecological) agriculture and have become an important part of the bio-industry and bio-economy.

Looking at the previous relevant policies, we can see that the industrial support policy for microbial fertilizers has been continuously strengthened. In the "Bio-Industry Development Plan" promulgated and implemented before, microbial fertilizers are included in the "Agricultural Biological Products Development Action Plan"; under the major policies and projects of the state and ministries, the microbial fertilizer industry is listed as a biological industry and a high-tech industry. and strategic emerging industries.

Thanks to policy support, the demand for microbial fertilizers has risen rapidly in recent years. According to relevant statistics, in 2013, the annual demand for microbial fertilizers was only 9.65 million tons, and it has increased to 15 million tons in 2020, which shows that the market's awareness and acceptance of microbial fertilizers is increasing.

At the same time, the market share of microbial fertilizers continues to rise. According to the statistics of the Ministry of Agriculture and Rural Affairs, the cumulative number of registered microbial fertilizer products in my country has increased from 149 in 2007 to more than 9,990 in February 2022. According to Li Jun, the annual output of microbial fertilizers in my country has reached 30 million tons, the annual output value has reached 40 billion yuan, and the cumulative application area has exceeded 500 million mu.

The release of the "Plan" will undoubtedly add new momentum to the development of the microbial fertilizer industry. Industry experts have predicted that the state will support and develop the microbial fertilizer industry in the "14th Five-Year Plan" and longer period, and it is expected to develop at a rate of about 10% every year.

Repair the soil and stand on the air outlet

No one can deny that chemical fertilizers are an important guarantee for China's grain production, but the unreasonable and unscientific application of chemical fertilizers over the years has brought a huge burden to our soil.

According to the national arable land quality grades announced by the Ministry of Agriculture and Rural Affairs (the national arable land quality grades are divided into 1 to 10 grades in descending order), the area ofChina's 1st to 3rd grades is 498 million mu, accounting for only 27.3%; the fourth to sixth grades 818 million mu, accounting for 44.8%; while the seventh to tenth grades have 510 million mu, accounting for 27.9%, nearly 1/3.

Due to high-intensity and extensive production methods, the topsoil in the black soil area ofNortheast China has been seriously lost, and the structure of farmland ecosystems has been unbalanced and its functions have been degraded. The average annual loss of surface layers is 0.3-1 cm, and the organic matter has dropped from 3% to 6% at the beginning of reclamation. %~3%; the problem of soil acidification in the south is prominent. According to monitoring, the proportion of acid farmland with pH value below 6.5 in 14 southern provinces has increased from 52.4% in the second soil census to 65.4%. Enhancement and destruction of microbial communities; salinization of soil in Northwest China, compaction of soil in North China, and soil pollution in the middle and lower reaches of the Yangtze River.

It is very urgent to improve the quality and repair the damaged soil. It is this demand that has strengthened the development of the microbial fertilizer industry. Studies have confirmed that microorganisms reduce pollution hazards through biosorption, biological passivation, etc.; by improving soil physical structure, bulk density, and water-stable aggregate structure, etc., improve soil biological fertility structure, and the balance of beneficial and harmful bacteria; reduce soil pollution, through Bioaccumulation and biotransformation, reducing heavy metal content.

In addition to soil remediation, improving fertilizer utilization is also an important role of microbial fertilizers. Some inoculants can increase the content of nitrogen, phosphorus and potassium nutrients in the soil, and can also improve the activity of some soil enzymes, which is conducive to the transformation of nutrients in the soil and facilitates the absorption and utilization of plants.

Microbial fertilizers can also enhance plant resistance. Some biological bacterial fertilizers grow and multiply in the soil, and gather in the roots of crops to form dominant flora. While growing on their own, they improve the surrounding environment and improve the stress resistance of plants. For example, mycorrhizal fungi grow in large quantities in the soil, the mycelium absorbs a large amount of nutrients, and also stores a large amount of water, which is conducive to the drought resistance of crops.

The soil environment has been improved, the nutrients absorbed by plants are adequate and balanced, the ability to resist drought and disease is improved, and the quality of agricultural products will naturally be higher. According to research reports, after the application of microbial fertilizer, the nitrate content of vegetables can be reduced by 25.4-44.3 mg/kg, which is 21% lower than that of the control; the content of vitamin C and sugar are both increased by 10%. Scientists also applied microbial fertilizers to cucumbers, tomatoes and leeks, and found that the sugar content of these three vegetables increased by 10%, of which glucose and fructose increased by more than 20% and 17%, respectively; crude protein, potassium, and vitamin C content increased by 11% %, the total organic acid content decreased by 9%, and the nitrite content decreased by 8%. Some microorganisms can also release hormones such as auxin, indole acetic acid, and gibberellin in the soil, which can regulate crop growth and increase yield.

It can be said that small microbes play a big role.
