Problems solved by technology

[0002] As we all know, China is a large agricultural production country. In recent years, with the rapid growth of population, people have used a large amount of chemical fertilizers and pesticides in order to increase crop production, resulting in the reduction of organic matter content in the soil, nutrient loss, soil acidification, compaction, nitrogen, phosphorus, etc. Potassium and other nutrient utilization rate is not high, the soil flora is unbalanced, biological activity is reduced, harmful bacteria and harmful substances are increased, soil fertility is seriously reduced, and the sustainable development of agriculture is seriously challenged
Although chemical fertilizers have the effect of increasing production, they also contain a variety of chemical components that are not conducive to the human body and the environment. The use of a large amount of chemical fertilizers in the one-sided pursuit of high yields leads to a decline in the quality of crops. The detection of pesticide residues and harmful substances in a large number of crops exceeds the standard, which makes human survival and health are seriously threatened
In addition, because a large number of farmlands also use sewage irrigation or are affected by the environment during the irrigation process, the soil condition is further deteriorated, and a large amount of harmful substances and heavy metal ions accumulate in the soil, seriously affecting the yield and quality of crops, affecting food safety, and affecting Hazard to human and animal health

Abstract

The invention discloses biological organic fertilizer with a soil remediation function and a preparation method thereof. The biological organic fertilizer is prepared from the components in percentageby weight: amino acid fermentation tail liquid, peat soil, a soil remediation agent, potassium fulvic acid, a microbial agent and rotted plant straw. According to the biological organic fertilizer, the specially-prepared soil remediation agent is adopted to synergistically act with a large number of organic substances and beneficial microorganisms, thus the activity of heavy metal ions Hg, Pb andCd in soil can further be lowered while the physical and chemical properties of the soil are effectively improved, absorption of the root system to harmful substances is inhibited, and a guarantee isprovided for safe production of crops.
