Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a biological organic fertilizer and a preparation method thereof.
Background
The fertilization is an important technical measure in agricultural production, and the reasonable fertilization can supplement soil nutrients and improve the crop yield. However, improper fertilization, especially long-term use of chemical fertilizers, can easily result in reduced organic content in soil, soil acidification and hardening, unbalanced soil flora, increased harmful bacteria and harmful substances, and reduced soil fertility. The abuse of chemical fertilizers and pesticides also causes the increase of harmful substances such as chemical residues in agricultural products and the like, reduces the quality and influences the health and survival of human beings. Therefore, the production of organic agriculture and pollution-free agricultural products is more and more emphasized by people, and the bio-organic fertilizer is expected to be developed in green agriculture and organic agriculture due to the unique biological activity and the soil improvement characteristic.
The bio-organic fertilizer is produced by inoculating beneficial microorganisms on the basis of the traditional organic fertilizer. The biological organic fertilizer contains a large amount of organic matters and beneficial microorganisms, and can improve the soil structure, repair the soil microorganism flora, inhibit the spread of harmful microorganisms and maintain the ecological balance of the soil. Besides containing major elements and trace elements necessary for the growth and development of crops, the biological organic fertilizer also contains microbial metabolites and a large number of active beneficial microorganisms, so that the biological organic fertilizer can promote the growth of crops, enhance the disease resistance of the crops, increase the yield of the crops and improve the quality of agricultural products.
Along with the development of economy and the improvement of the living standard of people, people pay more and more attention to the quality of agricultural products, and the green and environment-friendly bio-organic fertilizer has wide market prospect. The bio-organic fertilizer in China has many varieties, but the bio-organic fertilizer is not widely applied really, and the main problems are that the cost of the bio-organic fertilizer is high, the fertilizer efficiency is slow, and the quality is not stable enough. Meanwhile, in the growth and development process of plants, certain trace elements are needed, when certain trace elements are deficient, the growth and development of crops are obviously affected, the yield is reduced, the quality is reduced, and the application of the trace element fertilizer is gradually urgent along with the continuous improvement of the yield of crops and the large-scale application of chemical fertilizers.
At present, the trace element deficiency diseases of people all over the world are iron deficiency diseases and zinc deficiency diseases, the iron deficiency diseases can cause symptoms such as anemia, the zinc deficiency diseases can cause human body development disorder, even pica and other symptoms, and the current iron deficiency and zinc deficiency diseases of the human body are serious and mainly caused by insufficient dietary supply. At present, the deficiency of trace elements in human bodies is mainly solved through approaches of drug treatment, diet diversification and the like. The medication needs to be taken for a long time, which not only has side effects, but also is expensive. The diversification of diets requires extensive changes in food production, selection patterns, preparation methods and processing, which are difficult for many households. Therefore, a more economic, effective and safe supplementary way is sought, and the method has great significance for improving the current situations of iron deficiency and zinc deficiency of human bodies. Agricultural products including vegetables, soybeans, corns and the like are irreplaceable important subsidiary foods, are one of main foods for human beings, can provide various abundant and cheap vitamins, minerals and cellulose for the human beings, and are an important way for supplementing various nutrient elements for the human bodies. Therefore, the nutrient condition of human body can be improved by increasing the content of iron and zinc in the agricultural products.
