Insect repelling organic/inorganic compound fertilizer prepared from tobacco-waste and preparation method thereof

The invention discloses an insect repelling organic/inorganic compound fertilizer prepared from tobacco-waste and a preparation method thereof. The organic/inorganic compound fertilizer is prepared from the following components in percentage by weight: 30 to 35 percent of organic components and 65 to 70 percent of inorganic components, wherein 1) the organic components comprise: 80 to 90 percent of tobacco wastes, 8 to 20 percent of grass peat, 1 to 2 percent of ammonium sulfate, and 1 to 2 percent of calcium-magnesium phosphate; and 2) the inorganic components comprise: 5 to 40 percent of ammonium phosphate, 10 to 25 percent of phosphorous explosion-proof ammonium nitrate, 10 to 20 percent of potassium nitrate, 4 to 20 percent of urea, 1 to 5 percent of trace elements, 5 to 15 percent ofpotassium chloride, 0 to 20 percent of normal superphosphate, and 0 to 20 percent of potassium sulfate. The abundant botanical amino acid active ingredients in the fertilizer of the invention can enhance the nourishing effect of the fertilizer. After the proteins contained in the tobacco wastes are processed, most of the proteins are conversed into amino acids, which makes up for the defect of slow fertilizer efficiency of the organic fertilizer; in addition, the amino acid materials have a positive effect on the increase in the nutrition resistance of the crops and improvement in the qualityof the crops.
