Abstract

This study was conducted to investigate the effect of Actinomyces sp. and Bacillus sp., United States granular microorganisms and Japan granular microorganisms on turfgrass growth and thatch decomposing of creeping bentgrass in golf course by measuring turf color index, chlorophyll index, thatch content of soil, root length, turf density and chemical properties and thatch content of soil. Fertilizer treatment was designed as follows; control(CF; compound fertilizer), microorganism medium(M; CF+M), microorganism medium and livestock manure fertilizer(M-L; CF+M+LMF), microorganism medium, livestock manure fertilizer and amino acid liquid fertilizer(M-L-A; MM+LMF+ALF), United States granular microorganisms(USGM; CF+USGM), Japan granular microorganisms(CF+JGM). Soil properties investigated after experiment was scarcely affected by applied fertilizers in root zone of creeping bentgrass. The turf color index and chlorophyll index of M, M-L, M-L-A, USGM, JGM treatment were higher than those of CF. The turfgrass root in M-L treatment was longer than others. The thatch content of soil in M treatment was longer than others. The thatch content of M was decreased than that of CF by 6.8%. These was suggested that application of M induced the development of quality and growth of creeping bentgrass by assisting turfgrass growth and thatch decomposing.

본 연구는 Bacillus sp.와 Actinomyces sp.을 포함하는 미생물배양액, 일본산입상미생물 및 미국산입상미생물 등의 기능성성분을 포함하는 기능성비료의 시비가 크리핑벤트그래스의 잔디생육과 토양 대취분해에 미치는 영향에 대해 조사하였다. 처리구는 비료의 종류에 따라 대조구(CF), 미생물배양액(M), 미생물배양액과 가축분뇨발효액비(M-L), 미생물배양액과 가축분뇨발효액비 및 아미노산액비(M-L-A), 일본산 입상미생물(JGM), 미국산 입상미생물(USGM)였다. 시험 전후 토양분석결과, pH는 시험 후에 전보다 모든 처리구에서 약간 증가하였고, 시험 종료 후 처리구간의 토양화학성은 비슷하여 공시비료의 시비는 토양환경에 거의 영향을 미치지 않았다. 잔디생육 조사결과, 엽색지수와 엽록소지수는 관행구와 비교할 때, 처리구에서 높았고, 관행구과 처리구들사이에는 조사시기별 변화경향은 비슷하나 M-L-A와 M-L처리구에서 약간 높게 나타났다. 잔디뿌리는 M-L에서 더 길었다. 대취함량 조사결과, 관행구와 비교할 때, 처리구에서 감소하였고, 관행구와 처리구들사이에는 M처리구가 관행구보다 대취분해에 효과적이었다. 본 연구 결과, Bacillus sp.와 Actinomyces sp.을 함유하는 배양미생물 처리는 다른 미생물제제에 비하여 크리핑벤트그래스의 뿌리생육과 토양 내 대취분해를 촉진하여 잔디품질을 향상시키는 잔디성장촉진 기능이 있는 비료임을 알 수 있었다.
