A method of environmentally-friendly cultivating organic grapes with improved antihypertensive activity is provided to increase crop yield and functionality. An environmentally-friendly cultivation method for organic grapes comprises the steps of: improving soil by applying a compost, elvan powder and oyster shell powder to a vineyard between November and early December; preventing disease and insect damage by treating with antibacterial/germicidal agent for food addition 1 to 2 times a month between early March and late August; cutting a branch in-mid March, crushing and sprinkling to the vineyard; treating with a diluted chitosan solution by 10 days until early May when a new shoot is sent up to 20cm in early April; supplying nutrients to a grape tree and soil by sprinkling 100 to 150g mycelium of soil microorganisms to the grape tree between late May and early June; foliar spraying with a fermented mixture by 10 days when the new sprout is grown to more than 30cm in early June until a harvest season; harvesting when grapes are full ripe; and supplying the fermented mixture to the grape tree and soil 1 to 3 times from after harvesting to late October. The fermented mixture is obtained by selecting one or more components of fermented dropwort products, fermented mugwort products, wood vinegar and fermented calcium liquid and mixing with water, fermented grape products and chitosan liquid. The mycelium of soil microorganisms is obtained by sprinkling boiled glutinous rice to a bamboo forest, covering with a plastic film and leaving it along for 1 month. |
