Microbial fertilizer is the basic guarantee for the realization of the country's "one control, two reductions and three basics"

"China uses less than 9% of the world's land to feed a quarter of the world's population.
" As my country has a large population and a small land area, to solve the problem of food and clothing for everyone, the cultivated land cannot be fallowed and rotated like in developed countries, so it cannot be obtained.
Opportunity to recuperate.
Behind this miracle, the application of chemical fertilizers and pesticides has played a very good role in improving grain yield and ensuring the supply of agricultural products.
However, due to long-term overdose and unreasonable application of chemical fertilizers and pesticides, the land we depend on for survival has lost its original vitality.
At the same time, it has also brought severe challenges to the ecosystem and the quality and safety of agricultural products.
According to Liu Haiming, general manager of Beijing Aerospace Hengfeng Technology Co.
, Ltd.
, long-term large-scale application of elemental fertilizers has brought extremely serious effects on resources, ecology, environment, and human health.
? First, chemical fertilizers and pesticides are the prime culprits of non-point source pollution of soil.
According to data, for every ton of chemical fertilizer produced, more than 2 tons of carbon dioxide are emitted, while the annual output of chemical fertilizers (pure nitrogen) in my country is more than 50 million tons.
The production of chemical fertilizers alone will emit hundreds of millions of tons of carbon dioxide each year.
Magnitude.
On the other hand, the utilization rate of chemical fertilizers and pesticides is less than 30%.
The long-term large-scale use of single chemical fertilizers reduces soil activity and hardens and becomes acidic, which has become a stumbling block that hinders the continuous increase and high yield of agriculture.
? Second, excessive use of fertilizers and pesticides poses a great threat to human health.
In order to pursue high yields, people have an excessive dependence on chemical fertilizers and pesticides, resulting in large amounts of nitrite and harmful metals such as lead, arsenic, chromium, mercury, and cadmium remaining in soil and agricultural products, exceeding the standard, which not only doubles the number of sub-healthy populations, but also Various rare diseases are also increasing.
According to data, there are more than 3 million new cancers every year, and 80% of the many cancer patients are caused by long-term consumption of harmful residues such as nitrite, lead, arsenic, cadmium, mercury and so on.
Some experts also analyzed the "Suicide Village" in India, which detonated the topic of the circle of friends some time ago, and pointed out that the villagers' choice to commit suicide is related to the excessive use of pesticides.
? Third, excessive production of chemical fertilizers leads to depletion of resources.
Even if we don’t talk about the non-point source pollution brought by chemical fertilizers to the soil and the health hazards to humans, the unavoidable problem facing people at present is that coal and petroleum for the production of chemical nitrogen fertilizers are non-renewable resources, while phosphate and potash fertilizers are produced at the same time.
Mineral resources are also decreasing day by day.
According to statistics, there are currently about 130 billion tons of coal and oil reserves on the earth.
According to the current production level (3 billion tons are mined every year in the world), it will only be exploited by humans for another 40 years.
As the raw materials for fertilizer production, coal and oil, what should they do if they are exhausted after 40 years? ? Liu Haiming said "Under the national 13th Five-Year Plan for weight loss and drug reduction, the only effective way to promote the sustainable development of China’s agriculture is to reduce the amount of fertilizer input while achieving the goals of high yield, high quality, high efficiency, ecology and safety.
, Is to use the beneficial microorganisms in the soil to improve the crop rhizosphere micro-ecological zone, to release the rich insoluble phosphorus, potassium and trace elements in the soil, or to convert the hard-to-use substances of crops into effective and useful materials.
Nutrients, alleviate the contradiction between fertilizer supply and demand, and eliminate the adverse effects on the ecological environment.
Therefore, the development and application of microbial fertilizers are of particular importance in terms of resource utilization, cost reduction and efficiency enhancement, environmental protection and improvement of crop quality.
"? In Liu Haiming's view, microbial fertilizers will be a major measure to achieve sustainable development of agriculture.
Not only can all kinds of legumes, food crops, cash crops, vegetables and fruits, etc.
, be applied with microbial fertilizers to increase yield and improve quality, at the same time, pollution-free microbial fertilizers are also the basic guarantee for the realization of the country’s “one control, two reductions and three basics”.
It has become a new development trend in the production of safe and pollution-free agricultural products.
