The invention discloses a biology base air source and a flame retardant polyolefin compound formed by the biology base air source. The biology base air source is nitrogenous base subjected to surface treatment by a coupling agent, wherein the nitrogenous base includes A, G, T, C, U and A-T, G-C and A-U. The flame retardant polyolefin compound comprises polyolefin, a flame retardant, a synergist, a lubricant and an antioxidant; the a flame retardant is formed by mixing an acid source, a carbon source and the biology base air source. The flame retardant polyolefin compound has the following characteristics that the flame retardant effect is good; the addition quantity of the flame retardant is small; the efficiency is high; the cost is low; the advantages of good mechanical property and light weight of polyolefin are maintained; the product heat stability is good; the flame retardant and the synergist are matched with polyolefin processing and pyrolysis temperature; no decomposition or equipment corrosion exists in the processing process; the acid source, the carbon source and the air source achieve a synergistic effect; after the combustion, a compact expansion carbon layer is formed to protect a lower layer base body; the flame retardant performance of the compound is obviously improved; the compound can pass through UL94V-0 level; melting dripping resistant performance is realized.
