Abstract

The aim of this study was to evaluate the effect of 3 environment- friendly farming materials on the growth of pepper and tomato seedlings under low level of solar radiation. The pepper and tomato seedlings were separately grown on commercial substrate and non-fertilizer substrate under 30% shading condition, respectively. The microbe-, enzyme-, and amino acid-supplements were used for the foliar application to the seedlings. The application of enzyme- and amino acid-supplements significantly enhanced the growth of tomato and pepper seedlings grown on non-fertilizer substrate, while there was no significant effect on the seedlings grown on commercial substrate. The foliar application of enzyme- and amino acid-supplements reduced the days to flowering by 3 to 4 days and lowered the node order of fruit set in tomato plants grown on non-fertilizer substrate. The results showed that the enzyme- and amino acid-supplements could enhance the seedling growth and lower the node order of fruit set under limited nutritional conditions.

저일조 조건에서 고추와 토마토 유묘의 생육에 미치는 몇 가지 친환경농자재의 이용효과를 검토하고자 하였다. 친환경농자재는 미생물제재, 효소제, 아미노산제 3종을 이용하였고 30% 차광조건에서 토마토와 고추를 육묘하였으며, 육묘용 상토 종류에 따른 차이를 보기위해 일반 원예용(유비)상토와 무비상토를 비교하였다. 토마토와 고추 모두 무비상토에서는 효소제와 아미노산제 처리에 의해 묘의 생육이 양호하였으나, 미생물제재 처리는 대조구와 차이가 없었다. 유비상토에서는 친환경농자재 처리에 의한 생장촉진효과가 나타나지 않았다. 차광처리에 의하여 묘의 건물중은 감소하고, 엽면적은 다소 증가하는 경향을 보였으나, 친환경농자재의 처리에 의한 생육촉진효과는 없었다. 정식 후 토마토 1화방의 개화소요일수 및 착과절위를 조사한 결과, 무비상토의 경우 효소제 및 아미노산제 처리구에서 개화소요일수가 3~4일 적었으나, 착과절위는 차이가 없었다. 다만 차광조건에서 착과절위가 낮아지는 경향을 보였다. 유비상토의 경우는 친환경농자재 처리나 차광 유무에 따른 개화소요일수나 착과절위의 차이가 없었다. 고추는 무비상토에서 차광에 관계없이 효소제 및 아미노산제 처리구에서 건물중이 증가하였으나 미생물제재 처리구에서는 효과가 없었다. 유비상토는 친환경 농자재의 처리효과가 없었다. 따라서 시판되고 있는 효소제와 아미노산제는 무비상토에서 생육촉진효과가 있었으나, 미생물제재 처리는 처리효과가 없었고, 양분이 함유된 상토에서는 친환경농자재의 처리효과가 없었다. 또 차광에 의한 저일조 조건에서 친환경농자재의 혼용 처리에 의한 토마토와 고추 유묘의 생육촉진효과는 없었다.
