본 실험은 단고추 자루식 장기 양액배지에 있어서 암면 대체배지를 개발코자 암면구를 대조구로하여 훈탄, 펄라이트, 훈탄(3) : 펄라이트(7), 훈탄(1) : 펄라이트(1), 출탄(7) : 펄라이트(3)를 두고, 이들 배지종류가 생육 및 수량에 미치는 영향을 시험한 결과를 요약하면 다음과 같다. 1. 초장과 엽수는 처리간 유의성이 인정되지 않았으나 훈탄(1) : 펄라이트(1)구에서 경경이 굵고 지상부 건물중과 근중이 무거웠으며 T/R율은 작았다. 2. 과장과 과수 역시 처리간에 유의성이 인정되지 않았으나 훈탄(1) : 펄라이트(1)와 훈탄(3) : 펄라이트(7)구에서 과장과 과수, 평균과중이 컸고, 수량도 많았다. 3. 식물체분석 결과 잎과 뿌리에 함유된 전질소와 인산은 훈탄(1) : 펄라이트(1)에서 많은 편이었다. 4. 수량은 수확 개시 4월 이후부터 계속 증가하여 7개월 후인 5월에 가장 많았고, 훈탄(1) : 펄라이트(1)구에서 수확 초기부터 후기까지 다른 처리구에 비하여 많았다.
This study was conducted to select useful medium material as a replacement for the rockwool in long term bag-culture of sweet pepper. The sole use of perlite and carbonized rice hull(CRH) as well as their mixture with various combinations were compared to the rockwool. The results are summarized as the followings : 1. Plant height and number of leaves did not significantly differ among media. However, in the mixture of CRH(1) : Perlite(1), stem diameter was thicker; plant weight and root weight were heavier, and T/R ratio was lower. 2. Although fruit length and number of fruits did not significantly differ among media, the mixture of CRH(1) : Perlite(1) provided longer fruit length, more fruits, heavier fruit weight, and greater yield. 3. Monthly yield was continuously increased from the first harvest in November to the harvest in May next year. The amount of increase in the fruit yield of the mixture of CRH(1) : Perlite(1) from the first harvest to the final harvest was significantly greater than the amount of increase of other media. 4. The amount of total nitrogen and phosphate was higher in mixture of CRH (1) : Perlite(1), while the amount of other elements did not significantly differ among mixtures.
