Soil bacteria do not match. The soil is divided into acid and alkali. The organic fertilizer also has pH value. The bacteria are divided into fungi and bacteria. Neutral and slightly acidic soils should be applied with bacterial organic fertilizers. Alkaline soils should be treated with filamentous micro-organisms of algae organic fertilizers, which can fix nitrogen in the air after application and help crops use nitrogen nutrients in other states. Alkaline organic manure was applied to acidic soils. Acid and alkali neutralization reduced fertilizer efficiency and also caused strains to be harmed. Some bacteria are highly aerobic species, such as actinomycetes, molds, etc., and bacterial fertilizers containing such species are applied to soils with poor compaction and permeability. Not to mention fermentation, the strains themselves are difficult to survive. The effect of fertilization can be imagined.
Physical and chemical properties of the soil deteriorated. The conditions under which bacterial strains are used to survive are organic matter. However, more than 80% of the orchards, fields, and vegetable fields are currently using inorganic fertilizers, resulting in poor air permeability and resulting in the proliferation of some anaerobic bacteria, such as Fusarium, Slightly small nuclear bacteria, etc. What's more serious is that the lack of organic fertilizers destroys the structure of the soil pellets and reduces the soil's ability to retain fertilizer and water. The organic fertilizer for fruit farmers is generally about 40 kg per mu. The organic matter is quickly decomposed and used. The bacteria in the organic fertilizer loses the conditions for survival. It cannot survive and survive, and most of them die. This is also the reason why the fruit growers use organic products. Fertilizer found in the thick ground organic fertilizer has a role in the role of thin and no reason.
Don't know about the strains. As a new fertilizer, bacterial fertilizer is a blind spot for farmers. Each fungus has its unique properties and functions, and the grower must keep learning. As Bacillus, Bacillus glomus, Lactobacillus is a bacterial insecticide, the latter is more effective; Bacillus subtilis is a fungus, can effectively control the roots around the fungus, so that crops from infringement; Bacillus licheniformis is bacterial Prevent bacteria; EM bacteria resistance to weight loss.
The application temperature and method are wrong. Less than 5 °C strains can not be fermented, more than 35 °C bacteria will be burned to death, so the temperature of 5 °C ~ 35 °C application of bacterial fertilizer is effective. The organic fertilizer is best applied alone, do not mix with large fertilizers (nitrogen, phosphorus, potassium). The correct method of fertilization should be to use radioactive trenches to dig trenches that are 30 cm wide and 25 to 35 cm deep, first apply large chemical fertilizers, fill a layer of about 10 cm of soil, and then apply bacterial fertilizer. This isolation zone reduces the chance of large strains of fertilizer killing bacteria after water infiltration.
Insufficient organic matter in the soil. When there is enough organic matter or humus in the soil, it can be used by microorganisms, so that the soil microorganisms can be rapidly multiplied and nutrients can be activated. Taking orchard as an example, grass cultivation can be carried out, that is, when the grass grows 15 centimeters and less than 20 centimeters, the grass is cut. The ground is repeatedly covered once a year, and the entire garden is turned once every two years to increase the content of humus in the orchard; 3 to 5 years Once fermented cattle, pigs, sheep, chickens, rabbits and other domestic livestock manure provide an adequate matrix for the fermentation and propagation of organic bacterial fertilizers. This will not only provide the middle and trace elements for the growth of fruit trees, but also reduce the occurrence of physiological diseases such as leaflets and yellow leaves.
