Magnetized carbon-based fertilizer and preparation method thereof

Abstract

The invention provides a magnetized carbon-based fertilizer and a preparation method thereof. The magnetized carbon-based fertilizer comprises, by mass, 25-40 parts of agriculture and forestry wastes, 20-25 parts of fly ash, 15-18 parts of ammonium sulfate, 9-12 parts of urea, 6-8 parts of potassium sulfate, 1-2 parts of monoammonium phosphate, 9-13 parts of expansive soil and 1-2 parts of an adhesive. The preparation method of the fertilizer comprises the following steps: mixing above raw materials, deodorizing the obtained mixture with a composite microbial starter, carrying out piling fermentation on the mixture, turning the obtained pile and overturning to completely keep nutrients, carrying out high temperature fermentation to kill grass seeds with diseases and pests, decomposing the mixture to eliminate pesticide residual, drying and crushing the decomposed mixture, screening the crushed mixture to remove impurities, magnetizing the screened mixture, spraying a bacterial liquid, drying the sprayed mixture, and granulating the dried mixture. The preparation method has the advantages of no seasonal restrictions, low management cost, full utilization of resources, changing of wastes into valuables, realization of no peculiar smell of the produced organic fertilizer, harmless treatment, short organic fertilizer production time, simplicity in operation, convenience in management, substantial improvement of the earth temperature, prolongation of the effective period, soil improvement, and promotion of early growth and quick tillering of crops.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a magnetized carbon-based fertilizer. Background technique [0002] As we all know, the current global agricultural ecology is seriously unbalanced. The common use of chemical fertilizers in developed capitalist countries has been as high as more than 80 years. From the early 1980s to today in my country, the use of chemical fertilizers is increasing, the effective utilization rate of chemical fertilizers is getting smaller and smaller, and fungal diseases are rampant. , the growth rate of crop products is getting smaller and smaller, fungal diseases are rampant, and agricultural losses are huge. The fertile land has been seriously polluted by chemical fertilizers and pesticides, and the soil structure has changed, making it impossible to grow crops, especially the wheat shrivels, turns yellow and dies after emergence. If this continues, the consequences will be unim...

If this continues, the consequences will be unimaginable, and the agricultural losses will be huge! The severe pollution of the environment and soil has sounded the alarm for us

The world's three major crops, wheat, corn, and rice, have lost as much as 60 billion yuan in production due to fungal diseases. Frogs have disappeared, earthworms, the soil loosening experts, have left the field, and the soil surface area has shrunk (commonly known as hardening), drought resistance, and waterlogging resistance. , disease resistance has dropped significantly, and the production cost of crops has increased due to the manpower and material resources invested in drought resistance, disease prevention, and disease treatment.

Due to the single use of chemical fertilizers, insecticides and pesticides in large quantities, it not only restricts food production, but more importantly, it threatens the food safety of agricultural products and human health.
