What is a compound microbial fertilizer?

Compound microbial fertilizer: It organically combines inorganic nutrients, organic matter and microbial bacteria to reflect the comprehensive effect of inorganic chemical fertilizers, organic fertilizers and microbial fertilizers. River pollution, reduce the occurrence of pests and diseases, enhance the stress resistance of crops, and improve the quality and yield of crops.

Over the years, in crop cultivation, the amount of chemical fertilizers has been increasing, and the amount of organic fertilizers has become less and less, while the utilization rate of chemical fertilizers by crops is only about 30%, and about 70% of chemical fertilizers are deposited and fixed in the soil. Or run off into rivers with rainwater and not be absorbed and utilized by crops, which results in soil compaction, environmental pollution, eutrophication of rivers and groundwater becoming more and more serious, soil organic matter content decreases, fertility declines, and the living space for beneficial microorganisms in the soil becomes smaller. , the quantity is reduced, the disease resistance, cold resistance and drought resistance of crops are weakened, and the occurrence of diseases and insect pests is becoming more and more serious, resulting in the decline of crop quality and yield.

The promotion and application of compound microbial fertilizers on crops can not only improve the effective utilization rate of chemical fertilizers, but also increase the utilization rate of fertilizers by 10%-30%. The compound microbial fertilizer has been used continuously for more than two years, the number of beneficial actinomycetes in the soil increased by 8.4 times, and the nitrogen-fixing bacteria increased by 39 times, so as to achieve the effect of activating, loosening the soil, and improving the fertility of the soil. The chemical fertilizers that have been deposited and fixed in the soil for many years are activated and then absorbed and utilized by crops again. At the same time, the increase in the number of Bacillus lateralis in the soil can effectively control soil-borne fungal diseases and root-knot nematodes, and the control rate can be as high as 70-80%, which is comparable to that of chemical pesticides. Thereby reducing the use of chemical pesticides, improving the quality and yield of crops and the ability to resist continuous cropping.

It has very good effects in improving the utilization rate of chemical fertilizers, loosening the soil, reducing river pollution, fertilizing soil, reducing the occurrence of pests and diseases, and enhancing the stress resistance of crops.

The price of compound microbial fertilizer is higher than that of organic fertilizer, microbial inoculum, and bio-organic fertilizer. Mainly contains high inorganic elements.

Functional characteristics of compound microbial fertilizer

Complete nutrition:

It not only provides NPK and medium and trace elements required for crop growth, but also provides organic matter and beneficial microbial active bacteria for crops.

Fertilizer efficiency has the effect of slow release and improves the utilization rate of fertilizer:

In the production process, some inorganic nutrients are dissolved and then adsorbed and complexed by organic matter to form organic NPK, which is not easy to be lost and fixed when entering the soil. The utilization rate of chemical fertilizers can be increased by 10-30%, and the fertilizer efficiency can last for 3-4 moon.

Loosen the soil, dissolve phosphorus and potassium, and cultivate soil fertility:

After the fertilizer enters the soil, microorganisms multiply with the assistance of organic matter, inorganic nutrients, moisture and temperature, reducing the living space of harmful microbial groups, thereby increasing the number of beneficial microorganisms in the soil. The phosphorus and potassium elements deposited in the soil for many years are partially dissolved and released for the crops to re-absorb and utilize. After long-term use, the soil will become more and more loose and fertile.

Disease prevention, insect prevention and repeated cropping:

Microbial bacteria are in a dormant state in fertilizers. After germination and reproduction in soil, they secrete a large amount of chitinase, extracellular enzymes and antibiotics, which can effectively crack the spore walls of harmful fungi, nematode egg walls and inhibit the growth of harmful bacteria. , effectively control the occurrence of soil-borne diseases and insect pests, and play the role of preventing diseases and insects and resisting repeated cropping.

Rooting and strong seedlings, reducing nitrite content, improving quality, increasing production and income:

After the microbial bacteria multiply in the soil, they produce a large amount of plant hormones and organic acids, stimulate the growth and development of the root system, enhance the photosynthetic intensity of crops, and the crops grow with deep roots and leaves, which can effectively improve the sugar content of crop fruits and reduce nitrate and other harmful in crop products. The content of the material, improve the quality, and the crop yield can be increased by 10-30%. Accelerating the degradation of organic matter in the soil not only provides more organic nutrients for the growth of crops and improves the stress resistance of crops, but also reduces the living space of some pathogenic bacteria in the soil.
