염류집적 토양에서 광합성균, Soil plus, 목초액, 활성탄 등 토양개량제가 오이와 토마토의 생육과 수량에 미치는 영향을 시험하였다. 그 결과 활성탄이 수량을 증진시키고 뿌리의 활력도 좋았다. 토마토 배꼽썩음병도 활성탄 처리구가 가장 낮았다. 토마토의 당도는 Soil plus구가 높았으며 질산염과 인산함량은 처리간에 차이가 없었다.
To investigate effect of soil conditioners on salt reducing effect, saline soil were treated with photomicrobe, soil plus, pyroligneous liquor and active charcoal and cucumber and tomato were grown. Yield and root development were enhanced in active charcoal treatment overall and tomato blossom end rot frequency was lowest in active charcoal treatment. Total sugar content was highest in soil plus treatment and nitrate and phosphate content were not significantly different within 4 treatments.
