초록

지속가능한 친환경농업을 위해서는 비료와 함께 식물생장촉진 미생물 또는 생장조절물질을 적절히 혼합 사용하는 것이 바람직하다. 본 연구에서는 Methylobacterium oryzae CBMB20의 근권토양접종과 메탄올 엽면살포에 따른 고추의 생육촉진 효과를 유기질 비료의 시용 수준별로 조사하였다. M. oryzae CBMB20의 근권토양접종과 메탄올 엽면살포는 각기 고추생육을 증대시켰다. 또한 이들을 동시에 혼합 처리하였을 경우에는 고추의 생장촉진 효과가 더욱 현저하게 나타났다. M. oryzae CBMB20의 근권토양접종과 메탄올 엽면살포에 따른 고추 생장촉진 효과는 유기질 비료의 시용수준이 낮은 경우에 더욱 현저하게 나타났다. M. oryzae CBMB20와 메탄올을 혼합 처리한 경우 권장시비수준 100%와 300% 처리 사이에 고추생육과 수량에서 유의성 있는 차이가 없었다. 시비량이 지나치게 많을 경우 생장촉진제의 처리효과를 거둘 수 없으며, 적정한 시비 수준에서 M. oryzae CBMB20와 메탄올을 혼합 처리함으로써 고추를 비롯한 작물의 생장과 수량을 유지하면서도 시비량을 크게 줄일 수 있을 것으로 판단된다.

Fertilizers, plant growth promoting microbes and plant growth regulators should be combined together and used in order to achieve a maximal plant growth and yield in modern sustainable and ecological agricultural systems. In this study rhizosphere inoculation of Methylobacterium oryzae CBMB20 and foliar application of methanol were tested for their ability to promote the growth of red pepper plant at different levels of organic fertilizer. Rhizosphere inoculation of M. oryzae CBMB20 and foliar spray of methanol could promote red pepper plant growth and yield, and the growth promoting effect induced by the combined treatment of M. oryzae CBMB20 inoculation and foliar spray of methanol was more distinctive. This result suggests that a synergistic growth promoting effect of methanol spray and M. oryzae CBMB20 inoculation can be obtained in the combined treatment of the two growth promoting factors. The growth promoting effect was more significant in the lower fertilization rate, and the plant growth was not significantly different between 100 and 300% fertilizer treatments where both M. oryzae CBMB20 inoculation and foliar spray of methanol were included. This result indicates that, with the plant growth promoting effect of M. oryzae CBMB20 and methanol, fertilizer application rate can be profoundly reduced without any significant decreases in biomass accumulation and yield of crops.
