초록

본 연구에서는 중량식 라이시미터를 이용하여 토양 및 물관리 방법에 따라 배추와 옥수수 재배기간 동안 물수지를 평가하였으며, 작물 생산성과 물 부족 상황을 고려하여 작물 수분스트레스 계수와 최소 물 필요량을 산정하였다. 2018 년 배추 재배는 정식 2 주 후 빈번한 강우로 인해 관개가 실시되지 않아 무관개구와 적습관개구의 관개량 차이가 없었으며, 생산량 차이 또한 나타나지 않았다. 2018 년 배추 재배를 제외하고 배추와 옥수수 재배에서 적습관개구가 무관개구보다 생산량이 높게 나타났으며 대체적으로 증발산량 또한 높게 나타났다. 생산량과 증발산량은 밀접한 관련이 있으며 바이오매스 증가에 따라 증산작용이 활발해짐을 알 수 있었다. 작물 수분스트레스 계수는 배추 중기 0.8, 후기 0.8, 옥수수 중기 0.8, 후기 0.5 로 산정되었다. 배추와 옥수수의 최소 물 필요량(2017 년 배추 196.2 mm, 2018 년 옥수수 321.0 mm)은 적정 물 필요량(배추 239.4 mm, 2018 년 옥수수 466.9 mm) 대비 각각 82.0%, 68.8% 수준으로 나타났다. 이러한 산정 결과는 물부족 시기에 최소 관수량을 확보하여 작물 재배를 위한 물관리의 기초자료로 활용할 수 있을 것으로 생각된다.

In this study, we performed to evaluate the water balance during the cultivation of Chinese cabbage and maize according to the soil type and water management method using weighable lysimeters, and to estimate the crop water stress coefficient and minimal water requirement by considering crop productivity and water deficiency. In 2018, Chinese cabbage cultivation period was not irrigated due to frequent rainfall two weeks after planting, so there was no difference in irrigation amount between the non-irrigated and the irrigated and little difference in crop yield. Excluding the Chinese cabbage cultivation in 2018, in the cultivation of Chinese cabbage and maize, the crop yield of irrigated plots was higher than that of non-irrigated plots. The evapotranspiration of irrigated plots was also generally higher than non-irrigated plots. Crop yield and evapotranspiration are closely related, and transpiration is active as biomass increases. The crop water stress coefficients in the middle and the late stage were 0.8 and 0.8 for Chinese cabbage and 0.8 and 0.5 for maize, respectively. The minimal water requirements for Chinese cabbage and maize were 82.0% and 68.8%, respectively, compared to the optimal water requirements (239.4 mm for Chinese cabbage and 466.9 mm for maize). These results can be used as basic data for water management for crop cultivation by securing the minimum amount of irrigation in case of water deficiency.
