Tall fescue의 밀도변화에 미치는 토양경화와 공극률의 영향
Effects of Soil Compaction and Artificial Pore Space on the Shoot Density of Tall Fescue
초록
tall fescue의 밀도변화에 미치는 토양경화는 공극율의 영향에 대하여 조사하였다. 1. 토양경화에 따라서 토양경도와 용적중은 증가되었다. (Table 1). 2. 10kg 처리구(토양경도 2.5kg/
This experiment was to study the effects of soil compaction and artificial pore space on the shoot density of tall fescue (Festuca arundinacea Schreb.). Tall fescue subjected to compaction treatments with control, 10, 20 and 40 kg power roller, used for two times bi-weekly during six months. Artificial pore space treatments were control, 13.5, 37.5 and 84.5% at 0-lOcm depth, respectively. 1. Soil compaction increased soil hardness and soil bulk density.2. Compaction level of lOkg (soil hardness 2.5kg/
