Abstract

This study was conducted to evaluate effect of liquid fertilizer contained medium of Lactobacillus confusa and Pichia anoala on growth of creeping bentgrass(Agrostis palustris Huds. CV. Pennlixs). By application method of liquid fertilizer, the experiment plot was designed as following; NF was non-fertilized treatment, control was applied with compound fertilizer and treatment 1(T-1), treatment 2(T-2) and treatment 3(T-3) were applied with compound fertilizer and liquid fertilizer solution diluted 500, 300 and 100 folds, respectively. The every treatments was arranged a randomized complete block with three replications. Compared with NF, leaf color index of control, T-1, T-2 and T-3 in creeping bentgrass was increased 7.4%, 7.5%, 77% and 7.2%, respectively and chlorophyll content of T-1, T-2 and T-3 in creeping bentgrass was increased 45.7%, 45.6%, 52.1% and 49.6%, respectively, and T-2 and T-3 was increased 4.4% and 2.7% more than control. Dry weight of T-1, T-2 and T-3 was increased 2.7%, 13.8% and 13.9% more than control, when compared to control. These results were found that turfgrass qualities and growth was improved in treatment applied to compound fertilizer and solution of liquid fertilizer diluted 300 folds.

본 연구는 효모균과 유산균의 발효액을 함유한 비료가 크리핑벤트그래스 잔디의 생육에 미치는 영향을 시험하고자 2007년 8월부터 11월까지 SKY72 골프클럽 증식포장에서 수행하였다. 시험처리는 무처리구, 대조구, 처리구1, 처리구2, 처리구3로 3반복 난괴법으로 수행하였다. 시험기간 동안에는 토양화학성, 엽색지수, 엽록소함량 및 예초물량, 잔디분석 등을 조사하였으며, 그 결과는 아래와 같다. 토양화학성은 공시비료의 시비가 토양에는 별다른 영향이 미치지 않음을 알 수 있었다. 엽색지수는 무처리구보다 비료처리구(대조구, 처리구)에서 7.6% 증가하였으나 대조구와 처리구간차이는 나타나지 않았으며, 처리구 2에서 가장 높은 엽색지수 값을 나타내었다. 엽록소 함량은 무처리구보다 비료처리구(대조구, 처리구)에서 48.3% 증가하였고, 대조구와 처리구간 차이는 처리구 2과 처리구 3에서 각각 4.4%와 2.7% 높게 나타났으며, 시험기간 중 가장 좋은 잔디생육을 나타내는 처리구는 처리구 2로 조사되었다. 예초건물중은 무처리구 보다 비료처리구(대조구, 처리구)에서 83.6% 증가하였고, 대조구와 처리구간 차이는 처리구 2와 처리구 3에서 각각 13.8%와 13.9% 증가한 것으로 조사되었다. 시험 종료 후 채취한 잎의 무기성분은 시비구(CF, T-1, T-2, T-3)가 무처리구보다 질소는 82%, 인은 19%, 칼리는 42% 정도 증가하였고, 대조구(CF)와 처리구(T-1, T-2, T-3)사이에서는 비슷하였다.
