Microbial fertilizer

Abstract

The invention relates to a microbial fertilizer. The microbial fertilizer comprises 84-90% by mass of organic matters and 5-11% by mass of water and also comprises a strain, wherein the strain comprises at least two kinds of aerobic bacteria and at least one anaerobic bacterium; each aerobic bacterium is any one of bacillus subtilis, bacillus megaterium, bacillus stearothermophilus, bacillus sphaericus, bacillus firmus and saccharomycetes; the anaerobic bacterium is any one of bacillus circulans, bacillus licheniformis and lactobacillus acidophilus. The microbial fertilizer has the beneficial effects that the microbial fertilizer has the effects of overcoming the defects of the existing chemical fertilizers, reducing environmental pollution and activating soil; the content of beneficial biological bacteria in the microbial fertilizer is more than 0.3billion / g and biological activating enzymes and various trace elements are supplied, so that the quality of crops has a qualitative leap; through simultaneously containing the aerobic bacteria and the anaerobic bacteria, the microbial fertilizer can work under different conditions, thus increasing the output rates of the crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to microbial fertilizers. Background technique [0002] At present, the world is facing severe problems of population increase and environmental degradation, and the extensive use of inorganic fertilizers in agricultural production will also make environmental degradation more serious. The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year; After f...

Problems solved by technology

The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year; After farmland, the actual utilization rate is only 30% on average, and most of it flows into rivers and lakes with farmland drainage or remains in the soil, plants and crops, which not only brings environmental pollution but also endangers the safety and health of human beings and lives. These have become sustainable agriculture. Obstacles to sexual development; the above situations can be improved by using organic fertilizers, but there are many varieties of organic fertilizers in China. The dosage is very small, it cannot be used as the main fertilizer, and the effect is single, and the price is high
