액비 엽면시비가 켄터키 블루그래스의 생육과 질산염, 인산, 칼륨의 모래지반 토양을 통한 용탈에 미치는 영향

국문 초록 (Abstract)

엽면시비시 켄터키 블루그래스의 생육과 토양 용출수 중 질소, 인산, 칼륨의 용탈량을 조사하고자 본 연구가 수행되었다. 모래상토가 충진된 라이시미터에 켄터키 블루그래스를 식재하였다. 엽면시비용 복합액비로 FFA (fertilizer for foliar application, N-P₂O5-K₂O-Fe-Cu-Mn-Zn=13-2-3-1-0.1-0.2-0.2)와 대조구(복합비료, 입상, N-P₂O5-K₂O=16:4:8)를 사용하였다. 엽면시비는 연간 15 g (FFA15), 10 g (FFA10), 5 g N m<SUP>-2</SUP> (FFA5) 수준이었고, 살포 물량은 50 mL m<SUP>-2</SUP>으로 하였다. 켄터키 블루그래스의 엽색과 품질은 FAA15 처리구에서 증가하였고, 액비 살포량이 증가될 수록 고온기 초장과 근장이 증가하였으나, 지상부 및 지하부 건물중은 통계적으로 유의차를 보이지 않았다. 엽면시비 수준에 따른 질산태 질소 용탈량 범위는 13.24-88.09 mg N m<SUP>-2</SUP> 이고, 용탈률은 0.58-1.76% 이었다. 이상 결과를 종합하면 살포 물량 50 mL m<SUP>-2</SUP> 수준으로 액비를 엽면 시비시 여름철 고온기 잔디 색과 품질 유지가 가능했으며, 질소와 인산의 용탈량도 대조구인 입상복합비료 살포구와 차이를 보이지 않은 것으로 나타났다.

This study was conducted to investigate the effects of liquid fertilizer foliar application on the growth of Kentucky bluegrass. Lysimeter was established at the experimental site for the measurement of nutrient leaching as well as top and root growth of turfgrass. The liquid fertilizer used for the foliar application (FFA) was the compound fertilizer containing N.P.K (13:2:3)+microelements (Fe 1.0+Cu 0.1+Mn 0.2+Zn 0.2), and the granular compound fertilizer of N.P.K (16:4:8) was used as a check. The foliar application rates of liquid fertilizers tested in this study were 15 g (FFA15), 10 g (FFA10) and 5 g N m<SUP>-2</SUP> (FFA5) per year with spay water volume of 50 mL m<SUP>-2</SUP>. The experimental plot was laid out as the randomized block. Leaf color and quality of Kentucky bluegrass was good at the foliar application rate of 15 g N mv and the growth rate also increased as foliar application rate increased, but the top and root weight was not significantly affected by foliar application rates. The nitrate leaching following foliar application was 13.24-88.09 mg m<SUP>-2</SUP> indicating leaching rate of 0.58-1.76%, but it was not significantly different from those of the plot treated with the granular compound fertilizer. Kentucky bluegrass showed higher rating at leaf color, plant density and quality at the foliar application rate of 15 g N m<SUP>-2</SUP> per year with spay water volume of 50 mL m<SUP>-2</SUP>.
