Why do you have a good effect on the bio-fertilizer that you bought? The bacterial fertilizer is a kind of pollution-free new compound biological fertilizer which is prepared from the natural nitrogen-fixing bacteria species and scientifically formulated and combined. There are acid and alkali in the soil, and the pH of the organic fertilizer also has fungi and bacteria. Bacterial organic bacterial fertilizer should be applied to neutral and slightly acidic soils. The alkaline soil should be applied to the algae organic bacterial fertilizer of the filamentous microorganisms, which can fix the nitrogen in the air after application, and help the fruit trees to utilize the nitrogen nutrients existing in other states.

In fact, there are many microorganisms in the soil, and the quantity is also very large. Most of the microorganisms have a great influence on the growth and development of the crops, the agglomerate structure of the soil, and the material circulation. It also decomposes organic matter and minerals and releases nutrients for crop absorption and utilization.

The alkaline soil organic fertilizer is applied to the acidic soil, and the acid-base neutralization reduces the fertilizer efficiency, and the strain is also damaged. Some bacteria are highly aerobic strains, such as actinomycetes, molds, etc., which are applied to soils with poor permeability of the knot, not to mention fermentation and reproduction, and the strains themselves are difficult to survive.

During the application process, the following seven points must be noted.

1. According to the actual situation in the field. For soils with high sulfur content and rust fields, it is not advisable to apply biological fertilizers because sulfur can kill biological bacteria. According to soil moisture. The optimum temperature for applying the bacterial fertilizer is 25 ° C ~ 27 ° C, below 5 ° C, above 45 ° C, the application effect is poor. At the same time, it should be known that the suitable soil moisture of nitrogen-fixing bacteria is about 60%, that is, the moisture of the wet soil is most suitable.
2. Can not be mixed with other pesticides. In order to prevent the death of live bacteria, do not mix with fungicides, insecticides, herbicides and sulfur fertilizers, such as potassium sulfate and straw ash, because these drugs and fertilizers are easy to kill biological bacteria.
3. At the time of application, if the application of the fertilizer is contradictory to the prevention of pests and diseases, weeding may be carried out first, and then weeding and weeding after 48 hours. If seed dressing, avoid mixing with seeds that have been mixed with fungicide. At the same time, it should be prevented from being mixed with unfertilized farmyard manure, because farmyard manure will ferment in the process of decomposing, which will directly kill the bacteria.
4. Mix with fertilizers to pay attention to the amount of fertilizer can not be too large. High concentrations of chemical substances have toxic effects on microorganisms in the bacterial fertilizer, and in particular, they cannot be mixed with alkaline fertilizers such as ammonium bicarbonate and physiological alkaline fertilizers such as sodium nitrate.
5. It is suitable for quantity. For the application of biological fertilizers in fields with chemical fertilizers for many years, it is not possible to reduce the application of chemical fertilizers and organic fertilizers in large quantities. Because crops are dependent on chemical fertilizers, replacing nitrogen fertilizers with biological fertilizers cannot be adapted at once. Therefore, the agent should do it. The first, second and third years replaced 30%, 40% and 60% respectively. Phosphorus and potassium fertilizers can only make up and cannot be reduced.
6. It is suitable for the time. Biological bacterial fertilizer is not a quick-acting fertilizer, so it is best to apply it in the nutrient critical period of the crop and 7 to 10 days before the large absorption period.
7. Different types of bacterial fertilizer should not be mixed. At present, there are many kinds of bacterial fertilizers on the market, and the active bacteria contained in them are different. It is not clear whether they are mutually offset. If they resist each other, the fertilizer effect will be reduced.

In recent years, farmers have gradually paid attention to the application of bacterial fertilizer, but many farmers have reported that after applying bacterial fertilizer, the effect is not obvious. What is going on? The condition in which the bacteria in the bacteria fertilizer depend on it is organic matter. More than 80% of the orchards are using inorganic fertilizers, and the soil plate is poor in gas permeability, which causes some anaerobic bacteria to multiply, such as Fusarium and sclerotium.

What is more serious is the extreme lack of organic fertilizer, which destroys the agglomerate structure of the soil and reduces the ability of the soil to maintain fertilizer and water retention. The organic fertilizer used by the fruit farmers is generally about 40 kg per mu, and the organic matter is quickly decomposed and utilized. The conditions in which the organic fertilizers lose their survival cannot be proliferated, and most of them die. This is the effect of the organic fertilizer applied by the fruit growers in the application of commercial organic bacterial fertilizer, but the ground is thin and has no effect.

Soil is not conducive to microbe survival

The orchard does not apply organic fertilizer and shallow application of inorganic fertilizer for many years, resulting in soil compaction, poor oxygen storage, slow root growth, and changes in soil pH. The residue of the herbicide in the soil directly destroys the agglomerate structure of the soil and causes the microbes in the soil to die. After the application of organic bacterial fertilizer in the orchard, there is not enough microorganism in the soil to ferment and ferment the bacterial fertilizer to form an effective flora, which hinders the exertion of fertilizer efficiency.

If the orchard is to be properly selected, the herbicide should be able to weed and have a short residual time in the soil, which does not cause much damage to the microbes and soil aggregate structure in the soil. Pay attention to the application of organic fertilizer, and improve the soil for 3 to 5 years.

Don't understand the strain

This new type of fertilizer is a blind spot for farmers. Fruit farmers must continue to learn, to recognize that microbial fertilizer is not a universal fertilizer for all diseases. Each organic fertilizer has its properties and functions. For example, Bacillus globos is a bacterial insecticide, EM is resistant to heavy bacteria, and Bacillus lactis is a long-acting bacterial insecticide. Bacillus subtilis is a fungus that can effectively control roots. The surrounding fungi protect the crop from infestation, and Bacillus licheniformis is a bacterial defense.

Application temperature and method are wrong

First, the ground temperature should be applied within 5 to 35 ° C. If the strain is lower than 5 ° C, the strain cannot be fermented and propagated. If the strain is higher than 35 ° C, the strain will be burnt to death. The organic bacterial fertilizer is preferably applied alone, and should not be mixed with large chemical fertilizers (nitrogen, phosphorus, potassium).

The fruit growers are often used together with large chemical fertilizers. Dig a 20 cm deep and 25 cm wide ditch between the two trees, first sprinkle the bacterial fertilizer into the ditch, and then spread the fertilizer to fill the soil. This is no different from the mixed application. Large chemical fertilizer killed the strain.

The correct fertilization method should be carried out by radioactive ditch, digging a ditch 30 cm wide and 25-35 cm deep, first applying large chemical fertilizer, filling a layer of soil about 10 cm, and then applying fertilizer. This layer of belt reduces the chance of killing the strain after the large chemical fertilizer is dissolved in the water.

Insufficient organic matter in the soil

The key to the application of organic bacterial fertilizer is to continuously cultivate microorganisms in the soil. When there is enough organic matter or humus in the soil, it can be used by the microbial bacteria, so that the soil microorganisms can rapidly multiply and activate nutrients.

Implement an orchard grass system. When the grass grows to 15 cm and less than 20 cm, it will be cut, and the ground will be covered repeatedly for one year. The whole garden will be turned over once in two years to increase the content of humus in the orchard. 3 to 5 years, fermented cattle, pigs, sheep, chickens and other livestock and poultry manure. Provide sufficient matrix for the fermentation of the bacteria in the organic bacterial fertilizer. It provides medium and trace elements for the growth of fruit trees and reduces the occurrence of physiological diseases such as lobular and yellow leaves.

The role of microbial bacteria in the soil is mainly to produce various enzymes, decompose various nutrients, produce various acids and carbon dioxide, and provide more nutrients to the crops. The microbes must survive and multiply, and there must be enough organic matter in the soil.

Therefore, to improve soil fertility, the most important thing is to supplement the organic matter in the soil, and then to supplement the biological enzymes to ensure the survival of the bacteria; the enzymes, enzymatic bacteria, and the production of enzymes by the industrial production method to promote the nutrient absorption of the crops. digestion. Enzyme-containing organic fertilizer can really reduce soil salinization, create conditions for the survival and reproduction of microbial bacteria, and form a virtuous cycle of soil.
