Abstract

The invention provides a slow-release organic fertilizer for tobaccos and a preparation method thereof. The slow-release organic fertilizer for tobaccos is composed of lignin, kieselguhr, humic acid, calcium base silicic acid salt mine, nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, microelements and water, wherein the microelements comprise boric sulfuric acid, magnesium sulfate heptahydrate, molybdenum sulfate, ferrous sulfate, heptahydrate and single superphosphate. The preparation method of the fertilizer comprises dissolving and stirring the components, mixing and granulating to obtain the slow-release organic fertilizer. The slow-release organic fertilizer for tobaccos is reasonable in components; the utilization ratio of the organic fertilizer and the productivity of tobaccos are greatly increased through the synergistic effects of each component; at the same time, problems of eutrophication symptoms and nutrient deficiency symptoms of crops are effectively solved; tastes of tobaccos are greatly improved; at the same time, water pollution problems caused by fertilizer loss are effectively prevented; soil is improved, resources are saved, and costs are reduced. The preparation method is simple and suitable for the requirements of large-scale industrial production.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a slow-release organic fertilizer for tobacco and a preparation method thereof. Background technique [0002] Tobacco is the whole herb of Nicotiana tabacum L., a plant of the genus Nicotiana in the Solanaceae family. It is pungent, warm, and poisonous. It has the functions of reducing swelling, detoxifying, and killing insects. Treatment. [0003] Tobacco planting requires the application of chemical fertilizers. However, the use of chemical fertilizers artificially changes the evolution process of the soil, so that in the existing agricultural production process, the weathered minerals in nature cannot meet the needs of rapid growth of tobacco, resulting in a lack of nutrients. Artificial Auxiliary addition. However, tobacco requires as many as 17 kinds of nutrients, including carbon, hydrogen, oxygen; nitrogen, phosphorus and potassium; calcium, magne...
