What is Microbial Fertilizer? What is microbial fertilizer?

Microbial fertilizer is developed according to the principles of soil microecology, plant nutrition, and the basic concepts of modern "organic agriculture". 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 used in agricultural production. It has a history of nearly 50 years in China, from rhizobia agent - bacterial fertilizer - microbial fertilizer, from the name of the evolution has explained the gradual development process of microbial fertilizer in China.

The relationship between microbial fertilizers and fertilizers is a complementary and complementary relationship. In addition, the application of microbial fertilizers can also greatly improve the quality of agricultural products.

1. Microbial fertilizers cannot completely replace the use of chemical fertilizers. Especially in the agricultural product planting plots that only seek output but not quality, such as wheat, corn, etc., general microbial fertilizers should not completely replace the application of chemical fertilizers, otherwise it will increase input costs and reduce yields.

2. The application of microbial fertilizer can improve the utilization efficiency of chemical fertilizer. In the current planting mode, the utilization rate of chemical fertilizer is only 30% to 35%, and most of the remaining chemical fertilizer fertilizer efficiency is not absorbed and utilized by crops.

These lost fertilizers are either volatilized, fixed by the soil, or infiltrated into the ground. If the fertilizer of crops, the microbial fertilizer as the base fertilizer, the fertilizer as the top dressing, can greatly improve the utilization efficiency of the fertilizer, according to estimates, the utilization rate of fertilizer can be increased to about 70%.

3. Proper use of microbial fertilizers can reduce the amount of chemical fertilizers used. As mentioned earlier, the application of microbial fertilizers can increase the utilization rate of fertilizers, which makes it possible to reduce the amount of fertilizers used and provides guarantees. In addition, microbial fertilizers contain strains with nitrogen-fixing ability, which can fix nitrogen in the air and convert it into nitrogen fertilizer, which can also greatly reduce the amount of chemical fertilizer used.

Things to pay attention to when using microbial fertilizers

1. The application of microbial fertilizer has strict requirements for the environment, especially soil temperature, humidity, pH value, permeability and other factors, which have a great impact on the fertilizer efficiency of microbial fertilizer. For example, microbial fertilizers in the soil at a temperature of 18-25 degrees Celsius.

When it is more active, the activity will decrease below 15 degrees Celsius, and it will be dormant below 10 degrees, which is an important factor to consider when fertilizing.

2. When microbial fertilizer and chemical fertilizer are used together, it is necessary to adhere to the principle of using microbial fertilizer first and then using chemical fertilizer. Generally, it is required to use chemical fertilizer after three days of biological fertilizer to ensure that the beneficial bacteria in the biological fertilizer adapt to the environment in the soil and ensure the activity of beneficial bacteria to improve the fertilizer efficiency of chemical fertilizer. Especially not with sulfides.

Such as potassium sulfate and peracidic and alkaline fertilizers are used at the same time. Otherwise, it will backfire.

3. Microbial fertilizer should not be used at the same time as pesticides, and the simultaneous use will inhibit the growth and reproduction of microorganisms, and even kill microorganisms. Especially fungicides, insecticides, herbicides.

and plant ash.

etc., do not use together. Nor can microbial fertilizers be shipped with utensils and instruments that have been loaded with these pesticides.

Microbial fertilizer is a product with specific fertilizer effect, which can play a role in improving soil fertility, improving soil physical and chemical properties, improving quality, and increasing crop yield.

Increase soil organic matter, speed up soil remediation, improve fertility, and reduce the use of large chemical fertilizers. Resistance to heavy stubble and disease prevention, the effect is very good.

(1) Improve soil fertility. This is the main effect of microbial fertilizers, such as various autogenous, combined or symbiotic nitrogen-fixing biofertilizers, which can fix nitrogen in the air and increase the nitrogen content in the soil; A variety of microorganisms that decompose phosphorus and potassium minerals, such as silicate bacteria, can decompose potassium feldspar, mica and phosphate rock in the soil, so that the insoluble phosphorus and potassium in them are effective.

2) Manufacture and assist crops in absorbing nutrients. After the application of some bacterial fertilizers, due to the activities of microorganisms, it can not only increase the effective nutrients of the soil, but also produce a variety of hormones and vitamins, thereby promoting the growth of crops; The rhizobia in rhizobia fertilizer provides 30% to 80% of the lifetime nitrogen to leguminous plants. Va mycorrhizae is a soil fungus that can live in symbiosis with a variety of plant roots, and its hyphae extend far from the roots and can absorb more nutrients for various plants to use, among which the absorption of phosphorus is the most obvious.

3) Enhance the stress resistance of plants. After inoculation, some microbial fertilizer strains become the dominant bacteria in the rhizosphere of crops due to their large growth and multiplication in crop roots, and they can secrete antifungal and bacterial antibiotics, thereby inhibiting the growth of a variety of pathogens. Due to the large growth of mycorrhizal hyphae in the roots of crops, in addition to absorbing nutrients that are beneficial to the growth of crops, they can also increase the absorption of water by crops and improve the drought resistance of crops.

Use bacterial fertilizer as the base fertilizer, and you can choose to adopt the microbial agent.

To understand the role of microbial fertilizer, we must first understand the composition of soil: soil is composed of organic matter, minerals and microorganisms, of which microorganisms are divided into harmful bacteria and beneficial bacteria, if there are too many harmful bacteria in the soil, then there will be a variety of soil-borne diseases, such as gray mold, powdery mildew, root-knot nematode and so on.

At this time, microbial fertilizers are needed to regulate the soil.

Microorganisms are a major part of the composition of soil.

We call "microbial fertilizer" as "microbial fertilizer" every day, and we can see from the name that microbial fertilizer is divided into two aspects: "bacteria" and "fertilizer", in which "bacteria" refers to microbial fertilizer, and "fertilizer" refers to fertilizer, which can be used in combination to effectively improve soil problems and supplement the nutrients required by crops.

Microbial bacteria are an important part of the soil composition, in the case of continuous cropping and heavy cropping, the beneficial bacteria in the soil are absorbed and decomposed, and the harmful bacteria continue to grow, resulting in insufficient soil nutrients and slow crop growth. Therefore, it is important to add beneficial microorganisms to the soil in a timely manner.

The main role of microbial fertilizer is to improve soil activity and supplement crop nutrients, which is manifested in four aspects:

1.To improve soil activity, the beneficial bacteria in microbial fertilizer can effectively target the harmful bacteria in the soil, inhibit the growth of pathogens, and reduce the occurrence of crop diseases.

2.Provide the nutrients required by crops, and there are sufficient nutrients in the microbial fertilizer in addition to the fungicide, which can be supplied to the root system of crops in time to ensure the healthy growth of crops.

3.To improve the fertilization efficiency, the soil activity of the microbial fertilizer has been strengthened, and the root system has been grown, so the absorption rate of the fertilizer has been improved, and the effect of less application and high efficiency has been achieved.

4.To improve the growth environment of crops, rich organic matter can also improve soil physical properties, increase soil aggregate structure, so that the soil is loose, reduce soil compaction, is conducive to water retention, fertilizer conservation, aeration and promote root development, and provides a suitable microecological growth environment for crops.

Bio-organic fertilizer, implementation standard: NY884-2012, main technical indicators: more than 100 million bacteria, more than 40% organic matter, no requirements for nitrogen, phosphorus and potassium.

Bio-organic fertilizer adds functional microorganisms on the basis of organic fertilizer, such as actinomycetes, bacillus, photosynthetic bacteria, phosphate-calving and potassium-califying bacteria, etc.

Biological organic fertilizer is a kind of organic fertilizer, organic fertilizer in the process of commercial production using microbial fermentation and decomposition, can be natural fermentation or the addition of artificial strains to intervene in fermentation, to achieve the purpose of full decomposition and full sterilization.

According to the different raw materials, most of the microbial fertilizers are insoluble in water, and they are used as base fertilizers, which can be mixed with organic fertilizers, and the effect is particularly good. Beneficial bacteria survive in the soil, and a large amount of organic matter must be used as food for beneficial bacteria.

At present, the trading volume of this kind of fertilizer in the market is also relatively large. There are many organic fertilizer carriers of this kind of fertilizer, and the quality of this kind of fertilizer is relatively different, mainly because of the difference in the effective microbial activity quantity of microbial fungi. This kind of fertilizer also has the insufficient activity of the added microorganisms and fungi, and we must carefully identify it when choosing this kind of fertilizer.

Organic fertilizer containing microbial strains, in addition to providing organic matter to the soil, can also supplement the soil with microorganisms, microbial activities can activate the soil, but also improve fertilizer utilization!

Is it obtained by fermentation?

<> concepts are different: biological fertilizer generally refers to the product that makes crops obtain specific fertilizer effects through microbial activities, and microbial fertilizer refers to the biological fertilizer made by industrial cultivation and fermentation of one or several beneficial microorganisms.

The characteristics are different: biological fertilizer itself has no nutrients, but it can activate the soil and improve fertilizer efficiency through the activities of beneficial bacteria, and microbial fertilizer can promote the absorption of nutrients by crops or enhance the resistance to pathogenic microorganisms.

First, the concept is different

1. Biological fertilizer: In a narrow sense, it refers to the products that make crops get specific fertilization effects through the life activities of microorganisms, and in a broad sense, it refers to products that contain nutrients and microorganisms required by crops.

2. Microbial fertilizer: refers to the biological fertilizer made by industrial cultivation and fermentation of one or several kinds of beneficial microorganisms.

Second, the characteristics are different

1. Biological fertilizer: It does not contain nutrients, but contains a large amount of beneficial bacteria, which can activate the soil and improve fertilizer efficiency through the state macro activities of beneficial bacteria.

2. Microbial fertilizer: promote the absorption and utilization of nutrients by crops, or enhance the resistance to certain pathogenic microorganisms, reduce pests and diseases, so as to increase yield and improve quality.

Third, the mechanism of action is different

1. Biological fertilizer: accelerate the decomposition of organic matter, provide energy for the production and transformation of quick-available nutrients for the production of quick-available nutrients, and assist in the release of potential nutrients in the soil.
