NOVELTY - Nanometer selenium tourmaline functional water is prepared by preparing nanometer selenium organic base fertilizer, which comprises organic fertilizer, tourmaline powder, ore selenium powder containing 0.5% of nanometer selenium having weight ratio of (90.4-97.5):(0.8-1.0):(1.7-4.6). The organic fertilizer includes chicken manure, sheep manure, pig manure and human excrement in weight ratio of (0.5-1):(1-2):(2-3):(0.5-1). The chicken manure, sheep manure, pig manure and human excrement are weighed. The materials are agitated uniformly.    USE - Nanometer selenium tourmaline functional water.    ADVANTAGE - The nanometer selenium tourmaline functional water provides organic fertilizer, which is non-toxic and fast-acting.    DETAILED DESCRIPTION - Nanometer selenium tourmaline functional water is prepared by preparing nanometer selenium organic base fertilizer, which comprises organic fertilizer, tourmaline powder, ore selenium powder containing 0.5% of nanometer selenium having weight ratio of (90.4-97.5):(0.8-1.0):(1.7-4.6). The organic fertilizer includes chicken manure, sheep manure, pig manure and human excrement in weight ratio of (0.5-1):(1-2):(2-3):(0.5-1). The chicken manure, sheep manure, pig manure and human excrement are weighed. The materials are agitated uniformly. The obtained mixture is fermented, dried, crushed and sterilized to prepare organic fertilizer. The obtained fertilizer, tourmaline powder, ore selenium powder are weighed. Tourmaline powder and ore selenium powder are mixed. The obtained mixture is mixed uniformly with fertilizer to obtain the nanometer selenium organic base fertilizer. Nanometer selenium tourmaline functional water is prepared. The nanometer selenium tourmaline functional water comprises tourmaline granule, ore selenium powder containing 0.5% of nanometer selenium and tap water or deep well water in weight ratio of (1.5-2.5):(0.2-0.24):(90-110). The raw materials are weighed. Tourmaline granules are poured into tap water or deep well water to soak water for 24 hours. Tourmaline extract is taken and ore selenium powder is poured into the extract. The materials are agitated to dissolve the ore selenium powder. Nanometer selenium organic rice is planted.
