Microbial agentsIt has the functions of directly or indirectly improving soil, restoring soil fertility, maintaining the balance of rhizosphere microflora, and degrading toxic and harmful substances.
Compound microbial fertilizerIt is the organic combination of inorganic nutrients, organic matter and microbial bacteria, reflecting the comprehensive effect of inorganic chemical fertilizer, organic fertilizer and microbial fertilizer, and is the first fertilizer to resolve soil compaction, repair and condition soil, improve the utilization rate of chemical fertilizer, and improve fruit quality and yield.
Bio-organic fertilizerIt refers to a type of fertilizer with both microbial fertilizer and organic fertilizer effect, which is composed of specific functional microorganisms and mainly animal and plant residues and harmless treatment, decomposed organic matter and belly.
Agricultural microbial agents.
Microbial fertilizers have ecological adaptability, and the specific application methods and dosages should be determined according to local ecological conditions, crop varieties, soil types and tillage methods, so as to achieve better effects.
Microbial fertilizer can be used as base fertilizer, top dressing, furrow application or hole application, and can also be used for seed dressing, soaking, and dipping roots. Bio-organic fertilizer is generally used as base fertilizer, seed fertilizer and top dressing. In addition to being used as base fertilizer, seed fertilizer and top dressing, agricultural microbial agents can also be sprayed on the foliar surface.
It is mainly used as base fertilizer, top dressing and seedling fertilizer. The general dosage of solid microbial agent is about 2 kg mu, and it is mixed evenly with 40-60 kg of organic fertilizer. When the crop seedlings are raised, the solid fungus agent can be mixed into the nutrient soil and mixed with the soil, and then mixed into the nutrient bowl to raise seedlings; It can also dilute the fungus agent 10-20 times to mix seeds, dip roots, and spray roots; Diluted in a ratio of 1 to 100 for root irrigation and flushing; Dilute 500 times for foliar spray.
Compound microbial fertilizer.
used as base fertilizer 10-20 kg mu, applied together with organic fertilizer or farmhouse fertilizer; Top dressing 10-20 kg mu, crop growth period top dressing; Foliar sprays, diluted 500 times, foliar sprays.
Bio-organic fertilizer
100 kg of base fertilizer, which is applied together with farm fertilizer; Top dressing is about 7-10 days earlier than chemical fertilizer, and can be applied with reference to the amount of chemical fertilizer top dressing.
Biological agents can be divided into the following 5 categories according to their different effects:
1.Nitrogen-fixing agents: including rhizobia, nitrogen-fixing bacteria, nitrogen-fixing cyanobacteria, etc.;
2.Microbial agents that decompose soil organic matter: including organophosphorus bacteria and composite bacteria;
3.Bacterial fertilizers that decompose insoluble minerals in soil: including silicate bacteria, inorganic phosphorus bacteria, etc.;
4.Microbial fertilizers that promote the use of soil nutrients by crops: including mycorrhizal bacteria;
5.Bacterial fertilizers that resist diseases and stimulate crop growth: including antibiotic bacteria, yield increasing bacteria, etc.
1. Microbial fertilizers have strict requirements for soil conditions. The biological bacteria in the general bacterial fertilizer are most active in the soil when they are 180 -25 years old, when they are below 15 years old, when they are below 15 years old, when they are less than 10 years old, their activity ability is very weak, and even in a dormant state. Therefore, the use of microbial fertilizers pays attention to soil temperature and regulates soil moisture.
2. Pay attention to the fertilization period. After microbial fertilizer is applied to the soil, the biological bacteria need a process of adaptation, growth, nourishment, and reproduction, which can generally play a role after 15 days. If topdressed, apply before the crop's nutrient cut-off period. It should be applied in the early morning and late afternoon or on cloudy days without rain to avoid the killing of microorganisms by ultraviolet rays from the sun. Avoid use in high temperature, drought conditions.
3. Microbial fertilizer can not be soaked in water for a long time, and it should be applied in paddy fields for dry and wet irrigation to promote the activities of biological bacteria. Products based on aerobic microorganisms should not be used in paddy fields as much as possible.
4. The microbial agent has a good effect on the basis of applying sufficient organic fertilizer. If there is enough organic matter** in the soil, the organisms will multiply and inhibit harmful bacteria. Otherwise, the bacteria will die due to lack of food. Therefore, it is necessary to apply enough organic fertilizer before planting crops.
5. Microbial fertilizer can be used alone or mixed with other fertilizers. However, microbial fertilizer should be avoided mixed with unrotted farm fertilizer, otherwise, the high temperature generated by the fermentation of farm fertilizer will kill microorganisms and affect the fertilizer efficiency. In addition, avoid mixing with overly acidic and alkaline fertilizers.
6. Avoid using pesticides at the same time. Chemical pesticides will inhibit the growth and reproduction of microorganisms to varying degrees, and even kill microorganisms. Do not mix fungicides, pesticides, herbicides and sulfur-containing fertilizers (e.g. potassium sulfate, etc.) with plant ash. Tools that do not need to be mixed with pesticides and fungicides are loaded with microbial fertilizer.
7. Microbial fertilizer should not be put for a long time, and it should be applied in time after unpacking, and pay attention to the shelf life of the product.
