Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to organic 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 far...
