친환경농업기술 개발을 위한 벼 재배 시 벼의 생육 및 수량에 대한 두과와 화본과 녹비작물의 효과
송범헌,이경아,전원태,김민태,조현숙,오인석,김충국,강위금 한국작물학회 2010 한국작물학회지 Vol.55 No.2
동작물과 하작물의 작부체계와 녹비작물을 활용하는 벼재배 기술을 개발하기 위하여 2007년과 2008년의 2년 동안 충북대학교 농업생명환경대학 농장 답작 시험포장에서 공시 녹비작물로는 두과작물인 헤어리베치와 화본과작물인 호밀을 사용하여 배 재배시 녹비작물들의 효과를 조사분석하기 위하여 수행한 연구결과는 다음과 같다. 초장은 최고분얼기, 수잉기에서 출수기에 이르기까지 완만한 속도로 컸으며, 관행처리구에서 가장 큰 약 105 cm정도를 보였고, 녹비처리구들에서는 약 100 cm 정도로 뚜렷한 차이는 아니지만 헤어리베치, 헤어리베치+호밀, 호밀처리구순으로 초장의 크기를 보였다. 최고분얼기의 분얼수는 녹비처리구에서 관행처리구에서보다 더 많았으며 헤어리베치와 헤어리베치+호밀처리구는 비슷하고 호밀처리구는 관행구와 비슷한 분얼수를 보였다. 출수기의 유효분얼수도 최고분얼기와 비교해 그 수가 줄었지만 비슷한 경향이었으며, 헤어리베치처리구에서 가장 많은 포기당 19개 정도였다. 벼의 수량 및 수량구성요소는 헤어리베치처리구가 관행구에 비해 주당수수가 뚜렷이 많았으며, 수수당 영화수도 2008년에는 관행구에서 많았지만 전반적으로 헤어리베치구에서 많았다. 천립중과 등숙율에서는 큰 차이를 보이지 않았지만 주당수수와 수수당 연화수에 의해 정조수량은 헤어리베치처리구에서 관행구에서보다 2007년에는 5.3% 2008년에는 7.9%의 더 높은 수량을 보였다. 반면에 호밀구에서는 관행구에 비교해 수량이 현저히 떨어 졌다. The agricultural techniques of environmental friendly using the green manure crops have been required recently more to have the safety agricultural products and to reduce the use of fertilizers and agricultural chemicals. The utilization of green manure crops related closely to cropping system would be very important. The purposes of this study are both to investigate the effects of green manure crops of hairy vetch, legume, and rye, gramineae, and to compare the effects between them in rice cultivation. The hairy vetch and rye were treated as green manure crops into paddy soil at 10 days before the rice transplanting. The plant height was increased gradually from the maximum tillering to the heading growth stage, showing that it was the highest with treatment of conventional cultivation in 2007 and the highest with hairy vetch in 2008. The number of tillers was higher with treatment of hairy vetch and hairy vetch+rye than those with the conventional cultivation. Dry weight was also higher with hairy vetch than that with the conventional, while it was lower clearly in rye than those in hairy vetch and conventional. According to the high tilller number and spikelet number per panicle out of the yield components relatively, the yield of rough rice was increased to about 6% and 8% in 2007 and 2008, respectively, comparing with the yield in the conventional cultivation. Based on these results, the hairy vetch would be a good green manure crop in rice cultivation.

황기의 녹비작물 작부체계 활용 유기재배 시 생장반응과 수량에 관한 연구
송범헌,이경아,장윤기,김영국,안태진,안영섭,박충범 韓國藥用作物學會 2011 한국약용작물학회지 Vol.19 No.2
This studies were conducted to investigate the growth responses and yields of Astragalus membranaceus Bunge which were grown with organic cultivation using two organic fertilizers and two green manure crops of hairy vetch and rye in 2008 and 2009. The lengths of stems and roots were not clearly different between organic and conventional cultivations. The root diameters and the branch numbers were slightly thicker and more in all treatments of organic cultivation than that of conventional cultivation in 2008, although they were not significantly different between two cultivating methods in 2009. The dry weights of shoot and root were heavier on organic cultivation than those on conventional cultivation. The T/R ratios were commonly higher in organic culture, showing more clearly in 2008 than 2009. The yields were generally higher in organic cultivation than those in conventional cultivation in 2008 although the effect did not clear on yield in 2009. The organic cultivation using of organic fertilizers and green manure crops would be new method to have safety and qualitative products. The techniques of organic cultivation for Astragalus membranaceus Bunge would be studied more on utilizing the natural organic resources.

논토양에서 해가림 유형 및 품종별 인삼의 생육시기에 따른 생육특성, 건물생산 능력 및 수량성 비교
송범헌,장윤기,이경아,이성우,강승원,차선우 韓國藥用作物學會 2011 한국약용작물학회지 Vol.19 No.2
This study was conducted to examine major growth responses, the production and partitioning of dry matter on different growth stages, and yields and to select the optimal shading material in both quality and productivity of ginseng. Two cultivars of ginseng, Cheonpoong and Geumpoong, were cultivated in the paddy soil with three different shading materials; three-layered blue and one-layered black polyethylene (TBP), blue polyethylene sheet (BPS), and aluminium-coated polyethylene sheet (APS). Plant heights were linearly increased until June 24 and then maintained with showing higher height in Cheonpoong than that in Geumpoong cultivar. Root lengths were gradually increased until October 16. They were longer in Cheonpoong than that in Geumpoong cultivar, showing slightly longer with APS compared to TBP and BPS. The ability of producing dry matter of leaves was much higher from April to June compared to those of other growth periods, whereas its ability of root was concentrated from the end of June to the end of August. Among the shading materials, the ability of producing dry matter of shoot was higher with TBP than those with BPS and APS, while its ability of root was not appeared certain tendency unlike the shoot. The yield of ginseng roots was the highest with TBP among three shading materials and it was higher in Cheonpoong than that of Geumpoong cultivar. The shading materials which affect the light intensity and the temperature would be considered as an important factor to get better quality and productivity of Korean ginseng.

Growth responses and yields of cucumber, the populations of soil microorganisms, and the control value of nematodes were examined with six different treatments of chemical fertilizer, compost, microbial fertilizer(MF), and the combined applications of NPK + MF and compost. Cucumber, Eunseong Bakdadaki cultivar, was cultivated in the greenhouse. Higher plant height was appeared with treatments of the combined application of NPK + compost and NPK + MF compared to other treatments, especially at the early growth until 20th day after transplanting. Also, higher number of opened flowers showed with the combined treatments of NPK + compost and NPK + MF than those with others. The control value of nematodes at 60th day after transplanting with treatments of MF and NPK + MF was about 39.0% and 61.6%, respectively. The density of soil microorganisms was higher in order of actinomycetes, bacteria, and fungus. Their densities were not clearly different with treatments. Fruit yields of cucumber with treatments of NPK, compost, microbial fertilizer, and additions of compost and microbial fertilizer to NPk were higher, about 40 to 60%, than that with the control. The highest fruit yield was with NPK + MF and next highest fruit yield was with NPK + compost. It is assumed that the combined application of chemical fertilizers, compost, and microbial fertilizers would be increased the plant productivity. 본 시험은 농가관행 재배방법에 퇴비 및 토양미생물제인 "활력토" 입제를 이용하여 오이의 생장반응, 수량성, 토양미생물의 변이 등을 조사하기 위하여 은성백다다기 오이 품종을 공시하며 충북 청원군 소재 농가 비닐하우스에서 시험한 결과이다. 정식후 20일까지의 초장은 NPK구에 퇴비와 활력토를 추가 시용한 시험구에서 다른 시험구들에서보다 높았다. 건전한 꽃수 역시 생육초기에는 화학비료와 퇴비 및 활력토를 추가 시용 한 시험구에서 유의성있게 많았으나 정식후 25일이후에는 처리간에 뚜렷한 차이가 없었다. 활력토와 화학비료에 활력토를 추가 시용한 시험구들의 정식후 60일째의 선충방제가는 각각 39%와 61.6%였다. 오이 정식후 재배 토양의 토양미생물의 밀도는 방선균, 세균, 진균 순이었으며, 시험처리구별로는 뚜렷한 경향을 보이지 않았다. 오이의 상품성이 인정되는 과실수량은 대조구에 비해 시험처리구들에서 약 40%에서 60%까지 높은 수량을 나타냈다. 화학비료에 활력토와 퇴비를 시용한 시험구들의 수량이 다른 시험구들의 수량에 비교해 높은 수량을 보여 화학비료, 퇴비 및 활력토를 단일시용하는 것보다 혼용해서 이용하는 것이 효과가 있는 것으로 나타났다.
