李貞植,韓銀姬,柳炳悅 한국화훼연구회 1993 화훼연구 Vol.2 No.1
This study was carried out to obtain basic information on the proper native shade tolerant ornamental plants for the use indoor foliage plants. Four kind of native plants Calanthe discolor R. BR., Aceriphyllum rossi Eagler., Trachelospermum asiaticum var. intermedium Nakai., Saxifraga fortunei Hook var. incisolobate Nakai. and one introduced plants(Hedera helix L. 'Scutifolia') were grown in the differant temperatures arid light intensities to find out best growing indoor condition. Three temperature which were treated diurnal and nocturnal temperature 20/15℃, 25/20℃, 30/25℃ respectively and three light intensities were applied by shading 85%, 50%, and 0% of full sun were conducted and investigated for this sturdy. The results are summarized as fellows : 1.Calanthe discolor Lindl R. BR. Response of growth in the different temperatures and light intensities of Calanthe discolor R. BR., the best growth were resulted in the diurnal temperature 25℃ and nocturnal temperature 25℃ to compare with higher temperature treatments (30/25℃) and 50% shading plots of natural light showed more growth than that of growth in higher light. On the content of total chlorophyll had larger amounts in the 50% shading of natural light when to keep temperature 20/15℃, 25/20℃ than the high light (full sun) and high temperature (30/25℃). 2.Aceriphyllum rossi Eagler. were grown the best in the low temperature 20/15℃, and high light chlorophyll content also resulted condition the most in the low temperature(20/15℃) and high intensities, whereas were shown the least in the high temperature (30/25℃)and no shading. 3,In the Trachelospermum asiaticum var. intermedium Nakai. the growing condition was better growth chlorophyll content in higher temperature and higher light intensities. They gave resulted the most in 50% shading exceptionally whereas the others plots were next significant. 4.The best growth grave mere influence by the differences of light condition than tempera turn conditions in Saxifraga fortunei Hook var. incisolobate Nakai. Therefore, the 50% shading was the best growth in chlorophyll content when to keep the 30/25℃ and 50% shadings respectively. 5.In Hedrea helix L. 'Scutifolia' the growth was not particularly influenced by the different light intensities. The temperature 20/15℃ was the least growth among all light contidions. The figures showed higher content of chlorophyll in the temperautre 20/15℃, while 30/25℃ was the lower contents. These results might be thought Calanthe discolor Lindl R.BR., Saxifraga fortunei Hook var. incisolobate Nakai. can be easily use for indoor plants alike Hedera helix L. 'Scutifolia' in the evaluation of temperature and light condition. Whereas Tranchelospermum asiaticum var. intermedium Nakai. and Aceriphyllum rossi Eagler. might be thought difficult to grow the indoor because of adaptation in low light condition than temperature.
고온 및 화학약품 처리에 따른 국내산 화분용 유기질 배양토 원료의 C/N율 및 염기치환용량(CEC)의 변화
李貞植,柳炳悅,盧希宣 서울市立大學校 1995 論文集 Vol.29 No.-
화분용 배합토 원료로 국내산 유기질원료를 이용하기 위하여 볏짚, 왕겨, 톱밥, 땅콩껍질을 고온초리, 가성소다, 소석회, 알카리과산화수소처리를 하여 기존사용하던 피트모스, 부엽 및 관행배합토와 C/N율과 염기치환용량(CEC)를 비교분석한 결과 다음과 같다. 1. 질소함량이 높았던 재료는 땅콩껍질이었고 낮았던 재료는 톱밥, 왕겨였다. 탄소함량은 톱밥이 비교적 높았다. 전체적으로 톱밥은 매우 높아 다른것의 5∼6배 높았고 땅콩껍질이 가장 낮은 경향이었다. 볏짚은 무처리에 비해 모든 처리에 C/N율이 증가되었는데, 과산화수소와 소석회처리 및 온탕과 스팀처리에서 비교적 높았다. 왕겨도 과산화수소와 소석회처리에서 가장 높게 나타났다. 톱밥은 전처리중 가장 높았는데, 특히 소석회와 스팀 및 온탕처리에서 높았고 과산화수소에서 높은 편이었다. 그러나 땅콩껍질은 전체적으로 낮은 값을 보였으며, 가성소다 8%분무구와 소석회 및 온탕처리구에서 높은 경향이었다. 2. CEC의 변화에서 가장 높았던 재료가 볏짚과 왕겨였으며 다음이 땅콩껍질이었는데 전체적으로 톱밥이 가장 낮은 편이었다. 모든 재료의 물리, 화확적처리에서 피트모스나 부엽보다 크게 높았다. 왕겨는 온탕2시간처리와 소석회처리시 크게 증대되었다. 무처리에 비해 모든 처리에서 증가를 보였다. 볏짚은 온탕처리로 11배 이상 증가되었고, NaOH, 소석회 및 과산화수소처리에 의해 증가폭이 커졌다. 톱밥은 다른 재료에 비해 높지 않았으나 온탕처리와 과산화수소처리에서 높았다. 땅콩껍질도 원료의 CEC가 가장 높았으며, 소석회 및 온탕처리와 과산화수소처리에서 높았다. Four domestic raw materials were analyzed and evaluated in the four kinds of treatments which include as high temperature heat treatments, NaOH, Ca(OH)₂, alkaline H2O2 with comparison of conventional pot raw media for instance peat moss, leaf mold and mixed soil. The results are summarized as follows ; In C/N ratio change, rice straw had a tendency to increase in the treatment of H₂O₂ Ca(OH)₂ and heat treatments. H₂O₂ and Ca(OH)₂ treated for rice hull were getting higher for C/N ratio. In saw dust also it showed high its ratio by Ca(OH)₂, heat and H₂O₂ treatment against control. Whereas peanut hull showed a low ratio totally, but the plot of NaOH 8% spray, Ca(OH)₂ and hot water treatments trend to increase for it. In cation exchange capacity(CEC) change, rice hull was largely increased it by hot water 2 hours, Ca (OH)₂ in comparison with control. Also rice straw increased as much as 11 times against control particulary in case treatment for NaOH, Ca(OH)₂ and H₂O₂. Whereas saw dust were not high in all treatments to compare with other organic materials, whereas hot water and H₂O₂ showed more or less high. Peanut hull showed highest CEC in raw materials among four materials and there were high in Ca(OH)₂ and hot water and H₂O₂.
