Abstract
시설 딸기 유기재배, 무농약 및 관행재배 재배방법이 토양의 글로말린 함량 및 미생물생체량과 식물체 양분흡수에 미치는 영향을 검토하였다. 토양 총 글로말린 함량은 유기재배 $2.00mg\;g^{-1}$, 무농약재배 $1.93mg\;g^{-1}$이었으며 관행 재배는 $1.68mg\;g^{-1}$으로 유기재배에 비해 유의적으로 낮았다 (p<0.05). 토양 미생물생체량은 유기재배가 $821mg\;kg^{-1}$ 으로 무농약재배 $216mg\;kg^{-1}$ 및 관행재배 $169mg\;kg^{-1}$에 비해 유의적으로 높았다 (p<0.05). 딸기 지상부의 질소 흡수량은 유기재배가 $65kg\;ha^{-1}$로 가장 많아 질소 이용율이 52.4%로 가장 높았다 (p<0.05). 딸기 수량은 유기재배가 $51Mg\;ha^{-1}$으로 가장 많았으며 관행재배가 $35Mg\;ha^{-1}$이었고 무농약재배는 $32Mg\;ha^{-1}$이었다. Glomalin has important roles in soil aggregation in agricultural lands including controlled horticultural lands. The objective of this study was to measure total glomalin content of soils treated conventional farming system (CFS), conventional farming system without pesticides (CFSWP), and organic farming system (OFS) for strawberry cultivation under greenhouse in Goseong-gun, Korea. The average concentration of total glomalin in the soils was significantly higher in the OFS ($2.00mg\;g^{-1}$) compared to the CFS ($1.68mg\;g^{-1}$). In addition, soil microbial biomass C content was 4.9 times higher in the OFS ($821mg\;kg^{-1}$) compared to the CFS ($169mg\;kg^{-1}$). Nitrogen uptake rate of strawberry was higher in the OFS (52.4%) than that in the CFS (13.0%). Furthermore, yield of strawberry in OFS ($51Mg\;ha^{-1}$) was significantly higher compared to CFS ($35Mg\;ha^{-1}$).
