PURPOSE: A functional crop cultivation apparatus is provided to use nanosilver antibiotic ionized water and a lacquer extract which have excellent penetration force and antibacterial activity. CONSTITUTION: 1,000 g of silver oxide and 2,000 ml of watery nitric acid (10%) are mixed and heated at 80°C to dissolve the silver oxide. 0.3% of chlorine is added to the silver oxide solution, and the mixture is electrolyzed to obtain nanosilver water containing 500,000 ppm of nanosilver. 1,000g of lacquer trees or the bark of the lacquer trees is mixed with 10,000 ml of water, and the mixture is heated to obtain 1,000 ml of lacquer water. The lacquer water is mixed with 1,000g of nanosilver water, and the mixture is stirred for an hour to obtain a nanosilver lacquer extract. Seeds or roots to sow are soaked in the nanosilver lacquer extract. 1,000 ppm of nanosilver water or nanosilver lacquer extract is sprayed to an agricultural land after sowing the seeds or roots. The nanosilver water or nanosilver lacquer extract is supplied every 3-6 days by the kinds of the crops.
