The purpose of this study is to determine the amount of irrigation water for upland crop growth based on the 30 year of historical rainfall data and the water management guidelines as a reference. Five regions and ten crops were selected by their cultivation size. The changes of soil moisture conten...

밭작물 물관리 지침서란 무엇인가? | 밭작물 물 관리와 관련된 다양한 연구들이 진행된 가운데 농업인에게 보급된 농촌진흥청의 밭작물 물관리 지침서 (Eom et al., 1999)는 작물별, 생육시기별, 지역별로 관개 시기와 간격 그리고 1회 관개량 등의 정보를 토양 종류에 따라 물관리가 이루어질 수 있도록 정보를 제공하고 있다. 이를 통해 작물의 재배에 필요한 총 용수량 또는 시기별 용수량 등을 개략적으로 산정할 수 있게 되었다. | |
효율적인 물관리 방안을 위해 알아봐야 할 특성은 무엇인가? | 수자원의 변동성 증가에 따라 노지 밭작물에 큰 영향을 미칠 수 있기 때문에 기상 및 기후 특성, 작물의 종류, 지역 특성에 따라 효율적인 물관리 방안이 수립되어야 한다고 하였다 (Shin, 2017). 밭작물의 물 관리와 관련된 연구는 관개용수량 산정 방법 연구 (Suh and Lee, 2002; Hong et al. | |
용수 확보를 위해서 결정되어야 하는 것은 무엇인가? | , 2018). 이처럼 용수 확보가 우선적으로 필요한 지역에서는 작물에 필요한 용수량을 산정하고, 용수를 저장하는 적절한 시설의 규모 또는 적정 보관량 등이 먼저 결정되어야 한다. 농업용수의 저장 규모가 합리적으로 결정되어야 시설투자에 대한 부담이 적어질 수 있기 때문이다. |
