Abstract
A simple cultivation method using Jew's mallow (Corchorus olitorius L.) was examined to evaluate the biological quality of 72 upland soils collected from greenhouses in Korea. Each soil was mixed with 4-fold volume of sterilized basal soil having no indigenous chemical and physical problems to lessen the chemical and physical variations among original sample soils. This study assumes that the biological characteristics of each mixture 2 weeks after treatment reflect those of individual sample soil prior to treatment. Jew's mallow (Corchorus olitorius L.) was cultivated for 4 weeks in a pot filled with 250g of each experimental soil and the biological quality of each soil was estimated by the aboveground plant growth. The results indicated that microbial floral quality was explicitly deteriorated in 18 soils having EC above or equal to
우리나라 시설재배지토양(施設栽培地土壤)에서 채취(採取)된 72개(個) 밭 토양(土壤)에 대해 Jew's mallow(Corchorus olitorius, L.)의 유식물(幼植物)을 이용(利用)하여 토양(土壤)의 미생물성(微生物性) 간역(簡易) 평가방법(評價方法)을 시험(試驗)하였다. 검정토양(檢定土壤)의 이화학성(理化學性) 차이(差異)의 영향(影響)을 적게 하기 위해 각각의 검정토양(檢定土壤)에 이화학성(理化學性)의 문제(問題)가 없는 살균토괴(殺菌土壞)을 공통적(共通的)으로 4배량(倍量) 가(加)하여 혼합(混合)하였다. 이때, 2적(適) 배양(培養)한 혼합토괴(混合土壞)의 미생물성(微生物性)은 혼합전(混合前)의 미생물성(微生物成)을 반영(反影)하고 있다고 가정(假定)하였다. 1포트에 250g의 혼합토(混合土)를 넣고 Jew's mallow (Corchorusd olitorius L.)을 파종(播種)하여 4주간(週間) 재배(栽培)한 후(後)의 지상부(地上部)의 생육상(生育相)으로 부터 토양(土壤)의 미생물성(微生物性)을 평가(評價)한 결과(結果), 72토양내(土壤內) EC가
