Organic fertilizer and preparation method thereof

Abstract

The invention provides an organic fertilizer and a preparation method thereof. The organic fertilizer is prepared from the following components in parts by weight: 50-80 parts of crop waste, 25-40 parts of waste tobacco materials, 15-20 parts of excrement of livestock, 10-20 parts of inorganic nutrients, 1-5 parts of strain powder, 3-5 parts of lime, 10-18 parts of decomposed coal and 5-15 parts of peat soil. According to the organic fertilizer, the crop waste and waste tobacco materials are recycled, soil pollution caused by excessive chemical fertilizer usage can be avoided, pesticide usage can be greatly reduced, the quality and safety of agricultural products can be guaranteed, and vicious circle of the soil environment quality can be retarded, so that cultivated lands can be constantly and durably utilized.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an organic fertilizer and a preparation method thereof. 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 o...

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, otherwise, crops will grow slowly and pests and diseases will be serious, resulting in reduced production; the agricultural ecological environment will deteriorate, and chemical fertilizers will be applied to farmland Finally, the actual utilization rate is only 30% on average, and most of them flow into rivers and lakes with farmland drainage or remain in the soil, plants and crops, which not only brings environmental pollution but also endangers the health and safety of human beings and various creatures.

The problem of agricultural product pollution is becoming more and more prominent, the toxic residues of agricultural products are getting higher and higher, the quality of agricultural products is gradually declining, and the market competitiveness is also weakening. These have become obstacles to the sustainable development of agriculture; The more primitive methods such as landfill and landfill, in which the waste tobacco burned will release a large amount of carbon dioxide, causing serious air pollution; and the landfill of waste tobacco will also cause damage to soil and water sources

[0003] The above situations can be improved by using organic fertilizers, but there are many varieties of organic fertilizers in China. As the main fertilizer, and the effect is single, the price is high
