Fertilizer: You will use it?

Fungus is not good, used to know! In recent years, bacteria fertilizer into our sight, its unique biological function of bacteria in improving the soil, improve crop quality results have also been gradually recognized by farmers. However, due to the fact that most peasant friends have more control over the effectiveness of the bacteriostat, nutrient content and fertilization methods, it is difficult to achieve the desired results. Today we talk about the issue of bacterial fertilizer:

What is the role of bacterial fertilizer

Bacterial fertilizer is the common name of microbial fertilizer, it is a kind of auxiliary fertilizer with live bacteria. There are a large number of microorganisms in the soil (including bacteria, fungi, actinomycetes), generally contain hundreds of millions to billions of microbes per gram of soil. Some are good for crop growth and some are harmful. People use scientific methods to separate from the soil, breeding beneficial microorganisms, after training, breeding, made of bacteria agents, these agents used in agriculture, the crop yield, known as bacterial fertilizer. At present, China's production and application of bacteria mainly Rhizobium, nitrogen-fixing bacteria, phosphorus bacteria, potassium bacteria, EM bacteria and other fertilizers. Bacterial fertilizer is beneficial to microorganisms by antagonizing the harmful microorganisms through the life activities of beneficial microorganisms, promoting the transformation of nutrients in the soil, improving the effectiveness of soil nutrients, improving crop nutrient conditions and increasing soil fertility.

The role of bacterial fertilizer in the following areas:

1.1 to improve soil nutrient supply

Fertilizer mainly through a variety of bacteria to promote the dissolution of insoluble nutrients in the soil release. In the process of metabolism, the agent releases a large amount of inorganic and organic acid substances to promote the release and chelation of the trace elements such as silicon, aluminum, iron, magnesium and molybdenum in the soil, effectively breaks the soil compaction, promotes the formation of aggregate structure, Fixed ineffective fertilizers are transformed into effective fertilizers to improve nutrient supply, aeration and porosity in the soil.

1.2 to promote crop growth

The use of bacterium fertilizer promotes the production and regulation of stimulating hormone and promotes the growth and development of crops. The use of fungi can promote the production of gibberellins, auxin and other active substances.

1.3 enhance the ability of crop disease resistance

Some strains of bacterial fertilizer have the function of secreting antibiotics and various active enzymes to inhibit or kill pathogenic fungi and bacteria. A large number of field trials have proved that the application of bacterial fertilizer can reduce the incidence of pests and diseases and enhance the resistance of crops. Such as cotton yellow blight, rice blast, wheat powdery mildew, stalk rot, vegetable damping-off disease, blight, bacterial wilt and so have some control and inhibition, a large number of experiments show that Endemic microbial agents can be effective Inhibit the occurrence of certain species of nematode. Bacterial fertilizer is also obvious drought, cold, lodging, salt and alkali effects, enhance crop disease resistance, thus effectively preventing the occurrence of crop physiological diseases.

1.4 increase production, improve quality

The use of microbial fertilizers can increase the content of vitamin C, amino acids and sugars in agricultural products and effectively reduce the nitrate content, so that the agricultural products produced are delicious and good-looking, and they are selling at a good price. Can increase crop yield by 20-30% differently.

The correct application of bacterial fertilizer:

Fertilizer use less, the single application is not easy to apply, before the casing susceptible to the effects of sunlight, the wind and the wind will happen to run the wind can be mixed with organic fertilizer deep application of better, can also be mixed with nutrition soil Nursery vegetables, vegetables can also be applied when planting or ditch facilities.

(1) bacterial fertilizer long duration. Because of the strong vitality of biological bacteria, the general fertilizer up to 150 to 180 days, the first quarter of the crop is only applied once to meet the growth and development of the crop's life requirements.

(2) Bacterial fertilizer is a kind of active bacteria. When applied, it must be buried in the soil and can not be applied to the earth's surface. Generally it is applied to 7 ~ 10cm. As the biological bacteria on the crop roots and seeds do not cause any harm, so the application of microbial fertilizer should be close to the crop roots to maximize contact with the crop roots in order to give full play to biological fertilizer efficiency. For seed fertilizer, applied to the seeds just below the 2 ~ 3cm Department; as close as possible when the top dressing for the root system is good; foliar spraying should be carried out after 3 pm and sprayed on the back of the leaves to prevent ultraviolet light to kill Species.

(3) Fertilizer and other fertilizers with a good effect. Bacterial fertilizer is a kind of high content of biological agents, applied to the soil takes 15 to 20 days to play a fertilizing effect, the majority of biological bacteria need to be restored under the action of nitrogen, so the amount of fertilizers to be modest with a small amount Of nitrogen fertilizer, the general compound fertilizer per hectare 25 ~ 30kg, and according to different situations, with the application of 45 ~ 75kg urea, 75kg diammonium phosphate. If combined with organic fertilizers (80kg of organic fertilizer per hectare), the physical and chemical properties of soil can be accelerated, the content of soil organic matter can be increased, and the activity of biological bacteria can be increased.

(4) Maintaining suitable temperature and humidity conditions of soil: The bacterial fertilizer can be applied under soil conditions with soil water content above 30%, soil temperature between 10 and 40 ℃ and pH between 5.5 and 8.5. Watering in time when soil water content is less than 30%, and timely cultivating loose soil to maintain soil moisture, improve soil temperature.

(5) Preparation of nutrient soil: Generally take the pastoral soil (non-pesticide contaminated pastoral soil) 60kg, fully ferment the maturity of man, livestock and poultry manure 30kg, plus compound fertilizer 10kg, stir well. The nutrient soil can be used for crops, vegetables, fruits, fruit trees and other nursery, raising seedlings and other uses.

Application and promotion should pay attention to matters:

Biological Fungus plays a key role in the species, but the species is invisible, how to determine the pros and cons of a biological fertilizer?

First of all to see if there is no registration certificate of the Ministry of Agriculture, the Ministry of Agriculture registration certificate of the microbial fertilizer may be real;

Second, look at the sustainability of the brand, in general, the longer the brand, the higher the credibility;

The third point is that operators must do their own experiments. With these three basic can determine the advantages and disadvantages of bacterial fertilizer.

In addition, in the application process should note the following:

3.1 Valid and effective live bacteria At present, the effective life of microbial fertilizer in China more than 1 year survival time, so the optional fertilizer to be used as soon as possible, storage time is too long, the strain of dormancy may be destroyed. Bacteria effective bacteria can not reach the standard number of bacteria can not be purchased. The number of viable microorganisms of microbial agents in the state is more than 200 million / g (100 million particles / g), and the effective viable count of compound microbial fertilizer and bio-organic fertilizer is more than 20 million / g. If you do not meet this standard, indicating the quality of products can not meet the requirements.

3.2 temperature and humidity, soil and application of microbial fertilizer application of the best temperature is 25 ℃ ~ 37 ℃, less than 5 ℃, higher than 45 ℃, the application effect is poor. The high temperature, low temperature, drought conditions, crop plots should not be applied. Azotobacter fertilizer moisture content of the soil moisture is 60% to 70%. Sulfur-rich soil and rust paddy fields, should not be applied to fertilizer, because sulfur can kill biological bacteria. For thickened paddy fields, generally do not spread, with the spray method will be better. Biological fertilizer is not a quick fertilizer, nutrition critical period in the crop and nutrient absorption period of 7 to 10 days before the application, the best.

3.3 dosage and mix

Soil into the more fertilizer, although there will be no phenomenon of burning roots burning seedlings, but it is not applied to the more the better. The blind application of biological fertilizer in large quantities will increase the input cost of fertilizer and reduce the cultivation efficiency of crops.

Therefore, should be based on the needs of different crops and soil nutrients, the scientific determination of biological fertilizer amount of fertilizer in order to achieve the purpose of increasing production and income.

Remember: Do not mix the bacteriostat with fungicides, insecticides, herbicides and sulfur-containing fertilizers (such as potassium sulphate) and straw ash, as these drugs and fertilizers can easily kill biological bacteria. Or first fertilizer, every 48 hours, then fight weeding. If the seed dressing should not be mixed with germicide seed mixed use. Do not mix and decayed farmyard fertilizer.
