NOVELTY - Planting method of five-element vegetable including white radish, white radish leaf, black mushroom, carrot and burdock root, comprises preparing nano-selenium organic base fertilizer comprising organic fertilizer, diatomite, tourmaline powder, selenium containing nano-selenium and medical stone; sowing nano-selenium organic base fertilizer in ground, spraying nano-selenium tourmaline functional water and planting white radish, carrot and burdock root; and planting mushroom in ground with nano-selenium organic base fertilizer.    USE - Method for planting nano-selenium organic five-element vegetable including white radish, white radish leaf, black mushroom, carrot and burdock root used for preparing vegetable soup (claimed) useful for eliminating excess free radical such as hydroxyl free radical or lipid peroxide free radical, strengthening oxidation resistance ability, and increasing immunity.    ADVANTAGE - The method is safe for supplementing selenium from food and drink, and has strong selenium oxidation resistance effect.    DETAILED DESCRIPTION - Planting method of nano-selenium organic five-element vegetable including white radish, white radish leaf, black mushroom, carrot and burdock root, comprises:    (A) weighing fowl manure, pig manure and human manure, uniformly stirring, fermenting, drying, crushing and sterilizing to obtain organic fertilizer without toxic side effect; and weighing organic fertilizer, diatomite, tourmaline powder, selenium and medical stone, mixing the diatomite, tourmaline powder, selenium and medical stone, and then mixing with organic fertilizer to obtain nano-selenium organic base fertilizer;    (B) preparing first nano-selenium tourmaline functional water by filling tourmaline granule into the tap water or deep well water to immerse for 24 hours, taking the extract solution, and adding nano-selenium to dissolve;    (C) preparing second nano-selenium tourmaline functional water using the same method as step (B);    (D) stirring the sugar, plaster, nano-selenium and first nano-selenium tourmaline functional water, adding wood chips, wheat bran, sugar, plaster, corn powder, and uniformly mixing to obtain the nano-selenium culturing material as black mushroom inoculating material;    (E) planting white radish, carrot and burdock root: with organic vegetable planting method, before sowing the nano-selenium organic base fertilizer, scattering or digging hole or open groove, the using amount is 200-1000 kg/mu; after sprouting out of the vegetables, spraying the first nano-selenium tourmaline functional water during sunny day, the spraying times should be determined according to the vegetable growth condition; after the vegetable is ripe or has seeds, spraying the second nano-selenium tourmaline functional water in sunny day, and the spraying times should be determined according to the vegetable growth condition; and    (F) planting the black mushroom: uniformly scattering 300-400 kg/mu of nano-selenium organic base fertilizer in the mushroom ground, digging hole by hoe, spraying the first nano-selenium tourmaline functional water on the ground, the using amount is 200-300 L/mu, increasing selenium in the soil, mixing 125-175 kg/mu of nano-selenium organic base fertilizer with the mud, the weight ratio of nano-selenium organic base fertilizer to mud is 3:7, adopting it as debagged soil, after covering the soil, covering film for 2-3 days, preserving the temperature and changing the color, after spouting the mushroom, spraying water to the mushroom surface, if the soil is dried, irrigating tourmaline functional water to supplement water in the groove, controlling the temperature of mushroom tent to 18-22 degrees C, and keeping the ventilation.    The nano-selenium organic base fertilizer comprises (wt.%) organic fertilizer (94-97), diatomite (1.0-1.5), tourmaline powder (1.0-1.5), selenium (1.0-1.5) containing 0.5% nano-selenium and medical stone (0.5-1.0). The organic fertilizer comprises (wt.%) fowl manure (0.5-1), pig manure (1-5) and human manure (1-3). The first nano-selenium tourmaline functional water comprises tourmaline granule, nano-selenium containing 0.5% selenium, and tap water or deep well water at weight ratio of 1.5-2.5: 0.2-0.24: 90-110. The second nano-selenium tourmaline functional water comprises tourmaline granule, nano-selenium containing 0.5% selenium, and tap water or deep well water at weight ratio of 1.5-2.5:0.4-0.48:90-110. The nano-selenium culturing material includes wood chips, wheat bran, sugar, plaster, corn powder and nano-selenium containing 0.5% selenium at weight ratio of 70-75: 18-22: 0.8-1.2: 0.4-0.6: 4.5-5.5: 0.4-0.6. An INDEPENDENT CLAIM is included for preparation of nano-selenium organic five-element vegetable soup, comprising respectively washing white radish, white radish leaf, black mushroom, carrot and burdock root, drying at low temperature of 60-65 degrees C, mixing the white radish, white radish leaf, black mushroom, carrot and burdock root at weight ratio of 0.95-1.05:1.05-1.15:1.05-1.15:1.6-1.7:0.4-0.6, and packaging to conveniently use.
