AI Technical Summary

Problems solved by technology

However, long-term production practice has found that the absorption rate of various nutrients by tobacco leaves is different and non-linear, so controlled-release fertilizers were invented, mainly sulfur-coated and wax-coated technologies, but the utilization rate of instant fertilizers still cannot be solved. , and thus cannot solve the problem of eutrophication or deficiency of tobacco leaves and the water pollution caused by the loss of instant fertilizer

Abstract

The invention provides a slow release organic fertilizer used for a tobacco leaf and a preparation method thereof. The slow release organic fertilizer used for the tobacco leaf comprises lignin, kieselguhr, humic acid, calcium-based silicate salt, a nitrogen fertilizer, a phosphatic fertilizer, a potassium fertilizer, trace elements and water, wherein the trace elements are boron sulfate, magnesium sulfate heptahydrate and molybdenum sulfate. The preparation method comprises the following steps of dissolving and stirring the components, mixing and granulating. The slow release organic fertilizer used for the tobacco leaf has a reasonable formula, through cooperation of the components, the utilization rate of the organic fertilizer and the yield of the tobacco leaf are improved, the problem of eutrophy or nutrition deficiency of the crop can be effectively solved, the taste of the tobacco leaf is greatly improved, the problem of water body pollution due to fertilizer loss is effectively avoided, the soil is improved, resources are saved, and the cost is reduced; the preparation method is simple and is suitable for 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 leaves and a preparation method thereof. Background technique [0002] Tobacco planting process requires the application of chemical fertilizers, but the use of chemical fertilizers artificially changes the evolution of the soil, making the existing agricultural production process, the natural weathered minerals cannot meet the needs of rapid tobacco growth, resulting in nutrient deficiency, requiring artificial Assist to add. However, tobacco leaves require up to 17 kinds of nutrients, including carbon, hydrogen, oxygen; nitrogen, phosphorus, potassium; calcium, magnesium, sulfur; iron, boron, manganese, copper, zinc, molybdenum, chlorine, nickel, and different varieties of tobacco leaves Nutrient requirements are also different, so compound fertilizers, compound fertilizers, and soil-testing formula fertilizers h...
