Nutrient contributions of N, P 2O 5, K 2O, CaO, and MgO in rye were 9.1, 4.2, 11.8, 3.8, and 3.1 kg /10a, respectively. After incorporation of GMCs into soil, bulk density in soil with GMCs was lower than that in soil without GMCs (control). In soil after incorporation of GMCs, ph was not different in all treatment conditions, and ranged from 6.37~6.52. EC in soil after incorporation of GMCs was lower than that in soil without GMCs. The OM, T-N, and avail. P 2O 5 contents in soil with GMCs were higher than those in soil without GMCs. The tomato growths were increased in the rotational cropping system (RCS) as compared to continuous cropping system (control and without NPK). Also the density of Pseudomonas corrugata in soil with GMCs was lower than that in soil without GMCs (control). This study suggest that the RCS using GMCs showed lower disease outbreak density in soil for tomato cultivation as compared to RCS without GMCs. Especially, the GMCs was good effect for reduction of continuous cropping injury of tomato.

T-N 은 Kjeldhal 법으로, NH 4 -N 은건토 5g을 0.5M K 2 SO 4 50 ml로용액으로침출후 MgO 로알카리화하여증류법으로정량하였으며, NO 3-N은 NH 4-N을정류후 devarda s alloy를가하여 NO 3 -N을 NH 4 -N로전환시켜 증류법으로정량, 유기물은 Tyurin 법으로측정하였으며, 유효인산은 Lancaster 법으로비색계 (UV-1650PC, Shimadzu Co., Kyoto, Japan) 를사용하였다. 치환성칼륨, 칼슘, 마그네슘, 나트륨등의양이온은 1M NH 4OAc로추출하여 ICP(DV-4300, Perkin-Elmer, Norwalk, USA) 로분석하였다. 식물체분석은습식분해법 (H 2 SO 4 :HClO 4 =1:1) 으로전처리하여 T-N 은 Kjeldahl 법 ( 질소자동분석기, Gerhardt autosampler Vapodest 50 carouse, Germany) 으로분석하였고, T-P 는 Vanado molybdate 법 (UV 2550PC, Perkinelmer) 을사용하였다. 무기성분함량은습식분해법으로분해된용액을 ICP (DV-4300, Perkinelmer) 를사용하여각각분석하였다 (NIAST, 2000). 또한분석된토양화학성은 SAS 프로그램 버전 (2006) 을사용하였다. 결과및고찰토마토재배지에서녹비작물의생육특성토마토시설재배지에녹비작물의단작및혼작등재배방법에따른초장, 생체중및건물중을조사한결과 Table 3과같다. 각처리구별생체중및건물중함량은헤어리베치의경우는 46.0 및 4.8 g plant -1 이었으며, 호밀은 16.8 및 3.2 g plant -1 로헤어리베치가높은경향이었다. 단작및혼작에따른녹비 1주당생체중및건물중은단작의헤어리베치가가장높게나타났고, 그밖의처리구에서거의유사한결과를얻었다

4 韓資植誌 Korean J. Plant Res. 28(2) : 263~270(2015) 토마토재배지에서녹비작물의성분함량토마토시설재배지에서녹비작물의양분흡수비율은단작의경우헤어리베치의질소함량은 3.29%, 호밀의질소함량은 1.67% 였으며, 혼작의경우헤어리베치질소는 3.02%, 호밀의질소는 1.35% 로서헤어리베치의질소가호밀보다높았다 (Table 4). 헤어리베치는호밀에비해식물체내질소함량및기타무기물함량이높고, C/N 율이낮아서포장에서분해가빠르다. 생육후토양에피복하고 2주정도지나면모두분해되어, 후작물재배시질소비료시용량도감소시킬수있다고하였다 (Lee et al., 2013). 녹비작물생육시기별무기성분함량은재배기간이길어짐에따라감소하였다. 질소의경우도생육초기에함량이높고생육이진행됨에따라낮아지는경향을보였다. 단파에비해혼파의경우녹비작물에포함된질소의함량이감소하였다. C/N 율이높은호밀은헤어리베치와혼파재배시초기에질소를생산할수있는장점이있으며뿌리가깊어토양의통기성을좋게하는데이는 Jeon et al. (2011) 의보고와일치하였다. 또한녹비작물수확후미량원소 Fe, Mn, Cu 및 Zn 함량은단작및혼작에따라거의유사한결과를얻었다. 또한녹비작물수확후미량원소 Fe, Mn, Cu 및 Zn 함량은단작및혼작에따라거의유사한결과를얻었다. 녹비작물의 biomass 생산량및양분공급량토마토시설재배지토양에서녹비작물단파및혼파에따른 biomass 생산량은단파처리구인경우헤어리베치 (2,183 kg /10a) 가호밀 (2,154 kg /10a) 에비해높은경향으로녹비작물환원시토양유기물공급면에서호밀보다는헤어리베치가효과적일것으로판단된다. 혼파의경우 2,169 kg 10a -1 로단일처리인헤어리베치및호밀과유사성을보였다. 건물중면에서볼때단파처리구의헤어리베치와호밀이각각 515 kg 10a -1, 509 kg 10a -1 로나타났으며, 혼파처리에서 405 kg 10a -1 로나타나단일재배지가높은 biomass 량을보였다 (Table 5). 흔히두과인콩과화본과인헤어리베치를여름과겨울철에파종하여실험했을때, 겨울철에는두녹비작물간에별다른차이없이비슷한 biomass 량을보였으나, 여름철에콩은 4 kg /ha 였으며, 헤어리베치는 7.7 kg /ha 로큰차이가있다고보고된바있다 (Lee et al. 2008, Kim et al., 2013). 또한토마토시설재배지토양에서생육된녹비작물의토양환원시인 (P 2 O 5 ) 공급량은단파의경우헤어리베치가 5.8 kg /10a, 호밀이 4.2 kg /10a 였고, 혼파는헤어리베치가 3.1 kg /10a, 호밀이 2.5 kg /10a 였다. 토마토시설재배지에서녹비작물의토양환원시질소 (N) 공급량은단파의경우헤어리베치가 26.2 kg / 10a, 호밀은 9.1 kg /10a 였고, 혼파는헤어리베치 13.5 kg /10a, Table 4.

T-N 함량은녹비를토양에환원한후모든녹비처리구가처리전토양 ( 대조구 ) 에비해증가하는경향을보였다 (Table 7). 녹비작물중에서두과녹비는공중질소를고정하는능력이있어토양에환원시킨후에분해속도가화본과녹비에비해질소함량이증가한다고알려져있다 (Sung et al., 2008, Jeon et al., 2011). 본연구에서도두과인헤어리베치가화본과인호밀보다도질소함량이높게나타났다. 또한토마토시설재배지에서녹비작물의토양환원전 후토양의양이온함량및무기성분함량은 Table 8과같다. 양이온중 K의함량은호밀이포함된처리구의경우는약간증가하는경향이었고, 헤어리베치는감소하는경향이었다. 무기성분함량은전반적으로녹비작물처리전 ( 대조구 ) 에비해약간증가하는경향이었다

P 2 O 5 함량은녹비작물처리가대조구에비해증가하는경향이었다. 녹비작물토양환원에따른후작물인토마토생육은녹비작물처리는대조구에비해우수한생육을보였으나, 관행처리와는비슷한생육을보였다. 또한녹비처리에서토마토시들음병원균의밀도가현저하게감소하였다. 이상의결과를종합할때, 토마토시설재배지에서녹비작물의시용은비료로서충분한가치가있으며, 녹비작물토양환원후토양화학성을개선함으로써시설하우스토마토연작재배지의연작장해를경감할수있을것으로사료된다. 사사이논문은농촌진흥청의연구비지원 (PJ007358) 에의해이루어진결과로이에감사드립니다.
