How to apply biological fertilizer is reasonable?

In fact, there are not many restrictions on the application of biological fertilizer, because biological fertilizer itself is composed of organic matter and bacteria. Before being applied to the soil, the bacteria are dormant. There are a few points to be paid attention to:

1. It can be carried out at a suitable air temperature and ground temperature.

Although there is temperature control, when we apply biological fertilizer, it is before sowing and harvesting in spring, and after picking fruit in autumn, the ground temperature is generally at a reasonable temperature, so we don't need to mind.

2. Application method

Biological fertilizer cannot be applied to topsoil. This is because the bacteria are generally activated very quickly after the bag is opened, that is, the microflora activity is carried out in organic matter or soil. Without the corresponding organic matter as a guarantee, the fungus will quickly die of sunburn.

Therefore, biological fertilizer is suitable for digging pits or ditching. to ensure its microbiota activity.

3. Mixed application

Biological fertilizer can be mixed with a large number of elemental fertilizers, and the impact is not great, and it is not as harmful as people say, and it is not so impactful. If it is mixed with elemental fertilizer, it is better to avoid potassium fertilizer as much as possible, as there will be a slight loss of nitrogen in it. Biological fertilizer can also be mixed with refined fertilizer and farmhouse fertilizer, which can promote the further decomposition of organic fertilizer or the balance of fungus to a large extent.

4. Application amount

According to the reason, biological fertilizer should not be applied too much, mainly involving the balance of fungi. However, judging from the current general soil situation, soil microbial situation and fungus situation in biological fertilizers, there is no special dosage requirement. It's just a matter of controlling the amount of input from the perspective of value cost.

In the actual production process, more fruit and vegetable crops are applied than field crops.

5. Avoid contact with fungicides

The direct effect is that the contact between the two will cause the fungus in the biological fertilizer to be killed. Under normal circumstances, there is basically no chance of contact.

Biological fertilizer is already a relatively common and mature product, in addition to the attention of effective live bacteria, there is basically nothing particularly worth reminding, on the one hand, the use of biological fertilizer is to fertilize the soil, on the one hand, it is to mineralize the inorganic elements in the soil, on the other hand, it is to balance and restrict the fungi and achieve the balance of the flora.

Bacillus or yeast in biological fertilizer, if the number reaches sufficient, will form a certain beneficial flora, beneficial flora in the rhizosphere of crops can limit the reproduction and infection of harmful microorganisms, inhibit or "eat" harmful bacteria, so it has the effect of preventing and controlling soil-borne diseases.

You can bury this fertilizer in the soil, and then ensure the fertility of the soil, and when applying the fertilizer, you must avoid direct sunlight, add an appropriate amount of water, can not be mixed with pesticides and fungicides, do not use it when the temperature is relatively high or when it rains.

According to the use effect of biological fertilizer, as well as the expiration date of use, it can be used in combination with other fertilizers, so that the role of fertilizer can be reflected.

1. Biological fertilizer is suitable for rapid reproduction in the temperature of 15-35, especially under the condition of alternating dry and wet irrigation, and can play a good role in the activity of biological bacteria.

2. The water content of biological bacterial fertilizer applied in dry land should be between 30% and 60%, and the beneficial bacteria multiply rapidly. When the humidity is lower than 30%, it must be watered, and only the effective activity of biological fertilizer can help crops absorb nutrients in the soil. At the same time, biological fertilizer has a certain drought resistance.

3. It can be used as base fertilizer in the early stage of crop sowing. The beneficial bacteria in the biological fertilizer can antagonize the diseases and pests in the soil, promote the growth of crop roots, enhance crop immunity, improve the disease resistance and stress resistance of crops, and have a good effect on the growth of crops at the seedling stage.

4. Biological fertilizer is best applied in cool and suitable weather. For example, before 9 a.m. or after 4 p.m., or on cloudy days, because strong sunlight and ultraviolet rays will affect the effect of bacterial fertilizer.

5. Biological fertilizer cannot be directly mixed with fungicides. Spraying fungicides should be applied at an interval of 5-7 days before applying biological fertilizers, so as to avoid the activity of biobacterial fertilizers in the nutrition of fungicides.

6. The effect of biological fertilizer with fermented farmhouse fertilizer and compound fertilizer is better. After the application of biological fertilizer, the amount of compound fertilizer can be reduced, but the biological fertilizer cannot replace compound fertilizer, and an appropriate amount of compound fertilizer is needed. (Of course, this depends on the situation, if the bacterial fertilizer contains suitable nitrogen, phosphorus and potassium components, it can completely replace the compound fertilizer) farmhouse fertilizer is rich in organic matter, well decomposed, and applied together with bacterial fertilizer, which can promote the decomposition of organic matter and promote the better absorption of comprehensive nutrients by crops.

Biological fertilizer is applied to the soil, there is an adaptation process to reproduce, growth activities, its effective period is 7-10 days, it can gradually and evenly feed the plant, play a role, the effect period can be as long as 6-8 months.

Microbial fertilizer is a living fertilizer, which mainly relies on a large number of beneficial microorganisms to exert their vitality, and continuously transforms substances to show its benefits under the condition of vigorous reproduction and metabolism. The application of biological fertilizer method is stricter than the application of chemical fertilizer and organic matter fertilizer, and the application of microbial fertilizer should pay attention to the following matters:

It is important to ensure that the microbial fertilizer is applied within the expiration date to ensure the purity, number and activity of the microorganisms.

Microbial fertilizers can be applied to the soil alone, but they are more effective when mixed with organic fertilizers, which provide water retention and nutrients for microorganisms, which help beneficial microorganisms multiply in the soil.

Do not mix with chemical fertilizers, and do not apply chemical fertilizers for a short period of time after applying microbial fertilizers. One is to avoid the salinity of fertilizer salt being too high to kill beneficial microorganisms when dissolving, and the other is to avoid beneficial microorganisms from no longer playing their functions of nitrogen fixation, phosphorus solubilization, and potassium dissolution because fertilizer salt has provided the nutrients it needs.

Microbial fertilizers should be applied near the root circle of the crop to avoid being too far away from the root system to help the root system absorb nutrients. Therefore, microbial fertilizer should be mainly used as a base fertilizer.

It is best to use it up immediately after opening the bag, and if there is any unused microbial fertilizer, it should be properly stored and used up as soon as possible within a day or two. One is to prevent the multiplication of miscellaneous bacteria and damage the beneficial bacteria of microbial fertilizer, so that they become ineffective; The second is to prevent the spread of microorganisms in microbial fertilizer, although the strains used in microbial fertilizer must be safe strains, but if they are not properly checked, and a large number of microorganisms, whether beneficial or harmful bacteria, are released to the outside world to maintain the ecological balance of the environment is always negative.

Microbial fertilizer should be stored in a cool place, avoid sunlight, avoid high temperature, avoid moisture, avoid stacking and compacting and not breathable, avoid getting stained with acidic or alkaline substances, and there are quite a lot of contraindications.

In short, before the application of microbial fertilizer, the environmental conditions of the soil should be inspected, and if there is a deficiency, the soil should be improved, and the soil should be managed after application to ensure that the beneficial bacteria applied can multiply vigorously.

The special composition of biological fertilizer determines that it must have specific conditions for use. Soil environmental conditions will affect the application effect of bacterial fertilizer, such as temperature, light, soil moisture, pH value and application method. So you need to consider these aspects when using it.

Controlling the ground temperature, the activity of the biological bacteria in the general bacterial fertilizer is high when the soil temperature is 18-25, the activity below 15 begins to decline, and the activity ability below 10 is weak, and even in a dormant state. Therefore, it is very important to control the ground temperature after the application of bacterial fertilizer to vegetables in winter greenhouses. In winter, if you want to maintain a higher ground temperature, you must first control the temperature in the greenhouse to cause the ground temperature to rise.

Generally, the temperature in the shed should be kept at 25-30 during the day, and the temperature in the shed should be low at night. In order to avoid the loss of ground temperature and keep the ground temperature constant, in addition to mulching, it is also a good way to cover crop straw in the operation area.

Control the moisture of the soil, the insufficient soil moisture content is not conducive to the growth and reproduction of biological bacteria, but the soil is overwatered, the air permeability is poor, the oxygen content is low, and it is not conducive to the survival of biological bacteria. Therefore, in addition to controlling the ground temperature, it is also important to water properly. In general, watering should be carried out in the morning on a sunny day, because watering during this time is conducive to the recovery of ground temperature and the removal of moisture in the shed.

When watering, pay attention to watering empty and small water, and do not fall asleep. If the vegetable seedling is watered before mulching, the ground should be hoeed in time to increase the air permeability of the soil and promote the life activities of biological bacteria.

Pay attention to the application of Hongtong organic fertilizer, the role of biological bacteria can only be exerted under the premise of abundant soil organic matter. If the amount of organic fertilizer in the soil is insufficient, the biological bacteria will become ineffective due to lack of food. If there is sufficient organic matter** in the soil, the probiotics in the bio-fertilizer will multiply, increasing the control of harmful bacteria.

Therefore, before planting vegetables, it is necessary to pay attention to applying enough organic fertilizer.

Method: It is advisable to use bacterial fertilizer as basal fertilizer, furrow application, furrow application or hole application; It can also be used as top dressing, and the effect of applying biological fertilizer is better, and the biological fungus can quickly form a strong flora around the vegetable root system to protect the root system.

It is not advisable to use a variety of biological fertilizers at the same time. When using biological fertilizer, it is recommended to use one kind of Douqing group, and it is not advisable to use a variety of biological fertilizers containing different beneficial bacteria at the same time.

Different types of biological bacteria should not be replaced frequently, because biological bacteria fertilizer requires a large number of beneficial microorganisms to play its role. Different fertilizer products contain different main beneficial strains. Be careful to keep adding new fertilizers.

For example, after the base fertilizer is used up, the same biological fertilizer can be chased many times to expand the flora. In particular, it should be noted that biotic fertilizers cannot be used after application. Because the fungicide used in the soil can destroy the beneficial bacteria in the biological bacteria, the fungicide cannot be used at the same time as the biological bacteria.
