바이오황과 염화칼슘 혼합액의 엽면시비가 고추 생육과 품질에 미치는 효과

Abstract

This study was conducted to investigate the possibility of mixing Bio-Sulfur with calcium chloride and the appropriate concentration of applying Bio-Sulfur to pepper growth and quality. The treatments of foliar fertilization consisted of control (water), 2,000, 1,000 and 500 times diluted Bio-Sulfur without calcium chloride, only 0.2 % calcium chloride, and diluted Bio-Sulfur that was respectively mixed with 0.2 % calcium chloride. The plant height, number and dry weight of pepper fruits were highest in the treatment of 1,000 times diluted Bio-Sulfur. Whereas these decreased with increasing concentration of Bio-Sulfur in calcium chloride-containing treatments. The non-commodity rate of all treatments was lower than that of non-treatment due to the effect of plant control of Bio-Sulfur and calcium chloride. The calcium concentration of the leaves and pepper fruits in calcium chloride-containing treatments was higher than that of other treatments. The uptake of calcium of the pepper fruits decreased with increasing concentration of Bio-Sulfur in calcium chloride-containing treatments because of decreasing plant growth. In conclusion, the growth and uptake of major elements of pepper were lowest in the treatment of 500 times diluted Bio-Sulfur that was mixed with calcium chloride. Considering both pepper growth and quality, it is suggested that Bio-Sulfur diluted 2,000 ~ 1,000 times could be mixed with calcium chloride.
