초록

본 연구는 SAP를 국화(Chrysanthemum morifolium) 분화생산에 활용하고 SAP의 혼합 비율에 따른 물 사용량과 국화의 생육을 비교하고자 수행하였다. SAP를 배지의 부피비인0, 0.05, 0.1, 0.2%로 섞었으며 각각의 처리구는 토양수분함량 0.50m3･m-3로 일정하게 유지시켰다. 국화의 성장은 초장, 초폭, 뿌리 길이, 개화소요일수를 조사하였다. SAP 0, 0.05, 0.1, 0.2% 처리구에 따르면 식물체의 초장, 초폭, 생체중은처리구간에 유의한 차이가 없었다. 그러나 지하부 건물중에서는 0.2% SAP 처리가 대조구보다 유의하게 높았다. 실험 기간동안 SAP의 혼합 비율에 따라 사용되는 관수량에는 상당한차이가 있었다. 관수량은 0, 0.05, 0.1, 0.2% SAP 처리에서각각 43.5, 37.2, 30.1, 29.4L이었다. 결론적으로 동일한 토양수분조건하에서 SAP의 양에 따른 국화의 생육에는 차이가없었으나, SAP를 통해 토양의 보수력을 향상시켜 사용되는물의 양을 크게 줄일 수 있었다.

Plant drought stress may be reduced by superabsorbent polymer (SAP) by improving the water retention of the soil and substrate. This study was conducted to compare the growth of Chrysanthemum morifolium with water consumption according to the mixing ratio of the SAP. An experiment was conducted in an automated irrigation system using a soil moisture sensor to measure the soil moisture. The SAP was mixed at 0 (control), 0.05, 0.1, and 0.2% of the volume ratio of the substrate, and the soil moisture content of each treatment was kept constant at 0.50 m3･m-3. Plant growth was investigated using plant height, width, root length, and the days of flowering as variables. According to the SAP 0, 0.05, 0.1, and 0.2% treatments, there were no significant differences among treatments in plant height, width, and fresh weight.
However, the treatment of SAP 0.2% was significantly higher than the control in root dry weight. The total amount of water was 43.5, 37.2, 30.1, and 29.4 L in the treatments of SAP 0, 0.05, 0.1, and 0.2%, respectively. In conclusion, there was no difference in the growth of chrysanthemums according to the amount of SAP under the same soil moisture conditions. Still, the amount of water used could be significantly reduced through SAP by enhancing water holding capacity.
