Do you know the role of microbial fertilizer?
In recent years, with the increasing prominence of soil problems, biological fertilizer has become the darling of the fertilizer market, so what is biological fertilizer?
1. Definition of microbial fertilizer
As the name suggests, microbial fertilizer is a product that causes crops to obtain specific fertilizer effects due to the life activities of microorganisms, and is a kind of fertilizer commonly used in agricultural production. In fact, this kind of fertilizer has a history of nearly 50 years in the mainland, and it was a rhizobia agent as early as a rhizobia agent, then to a bacterial fertilizer, and then to the current microbial fertilizer.
We have always thought that it is a highly efficient fertilizer, and some people say that it can completely replace chemical fertilizers, and some people think that it is not a fertilizer at all. Actually, both of these are prejudices. Many years of experiments at home and abroad have proved that inoculating soybeans, peanuts and other leguminous crops with rhizobia can improve the efficiency of symbiotic nitrogen fixation, and indeed have the effect of increasing yield. As long as it is a microbial fertilizer, the above effects can be achieved, so it is very important to choose a good bacterial fertilizer.
Second, the role of microbial fertilizer
1. The role of improving the utilization rate of chemical fertilizers
Because of the large use of chemical fertilizers, the utilization rate of chemical fertilizers continues to decrease, only by increasing the application of chemical fertilizers to improve crop yields is limited, but also cause environmental pollution problems.
2. The role of soil improvement
The beneficial microorganisms in microbial fertilizers can improve the structure of soil aggregates, enhance the physical properties of soil and reduce the loss of soil particles, and can also participate in the formation of humus, which can improve soil physical properties and soil fertility.
3. The role in the production of green food
While people's living standards continue to improve, the requirements for the quality of life are also getting higher and higher, and green agriculture is actively developing at home and abroad to produce safe and pollution-free green food. In this process, it is required not to use or minimize the use of chemical fertilizers, chemical pesticides and other chemical substances, and not to cause the production and accumulation of harmful substances in the application object, that is, there is no adverse impact on the ecological environment. In recent years, some microbial fertilizers at home and abroad, especially imported bacterial fertilizers, can not only alleviate or reduce the pollution of agricultural products, but also improve the quality of agricultural products.
4. The role of microbial fertilizers in environmental protection
Using the specific functions of microorganisms to decompose and ferment municipal solid waste and agricultural and animal husbandry wastes to make microbial fertilizers is an economically feasible and effective way, and researchers are also researching it.
total
The role of microbial fertilizer in agriculture has gradually been recognized, now there are more than 70 countries in the world to produce, apply and promote microbial fertilizer, the promotion area of microbial fertilizer in Israel is currently wide, from the technical point of view, Israel's agricultural technology is in the forefront of the world, so in this aspect is more believable!
Of course, there are more than 200 enterprises in the mainland with an annual output of about hundreds of thousands of tons of microbial fertilizer used in production, although the production volume is very small compared with large fertilizers, but it also plays a role in agricultural production, and also occupies a place in the domestic fertilizer industry, and has achieved certain economic benefits and social effects, has initially formed a formal industrial production stage, which shows that the development prospects of microbial fertilizer in China are very good!
