Abstract

This study was conducted to evaluate to the effect of liquid fertilizer with saponin (SLF) and liquid fertilizer with amino acid (ALF)on the growth of creeping bentgrass. In creeping bentgrass, turf color index, chlorophyll index, dry weight and shoot number were measured. It was hardly affected by SLF and ALF applications in investigation of chemical properties of the soil. By applying SLF and ALF, turf color index and chlorophyll index in 2SLF and 2ALF were increased more than CF, and shoot number and root length in 2SLF, ALF and 2ALF were higher than CF. In correlation coefficient among growth factors of creeping bentgrass, turf quality was significantly different in root length, shoot number, dry weight, and content of N and K in turf tissue (P<0.05), N content of tissue was significantly in root length, shoot number and dry weight (P<0.05), and K content was significantly in shoot number and dry weight (P<0.05). These results suggested that application of functional liquid fertilizers such as SLF and ALF was expected to replace compound fertilizer in turf management and that applied SLF and ALF was stimulated the uptake of N and K into turf so that turf qualities were improved by enhancing growth shoot and root of turf.

본 연구는 사포닌과 아미노산 함유비료를 크리핑벤트그래스에 관주시비하여 잔디생육에 미치는 영향을 조사하여 복합비료를 대신하여 잔디관리에 이용할 수 있는지 평가하기 위해 수행되었다. 엽색지수, 엽록소지수, 건물중, 잔디밀도, 뿌리길이 및 잔디의 양분함유량을 조사하여 생육을 평가하였다. 시험 전후 토양분석결과, 처리구에 따른 토양화학성의 변화는 나타나지 않아 SLF와 ALF의 시비가 골프코스의 토양화학성의 변화에 영향을 미치지 않음을 확인하였다. 벤트그라스의 엽색지수와, 엽록소지수는 2SLF와 2ALF에서는 엽색지수와 엽록소지수가 CF와 비슷하거나 약간 높았고, 잔디밀도와 뿌리길이는 2SLF, ALF 및 2ALF에서 CF보다 높았다. 건물중과 잔디 중 질소와 칼리함량은 2ALF 처리구에서 가장 높게 조사되었다. 잔디품질은 뿌리길이, 잔디밀도, 건물중 및 질소와 칼륨함량에 대해 고도의 상관성을 보였고(P<0.05), 잔디에 함유된 질소는 잔디밀도, 뿌리길이 및 건물중과 같은 잔디생육과 높은 상관성을 보였으며(P<0.05), 잔디에 함유된 칼륨은 잔디밀도와 건물중에서 높은 상관성을 보였다(P<0.05). 이러한 결과를 통해 기능성물질이 함유된 비료는 복합비료를 대신하여 잔디관리에 이용할 수 있을 것으로 기대되었고, 기능성액상비료의 관주시비 시 질소와 칼륨이 잔디에 흡수되어 잔디 지상부 및 지하부생장과 밀도를 증가시킴으로써 잔디품질을 향상시키는 것을 알 수 있었다.
