딸기 및 적환무의 관개용수 염도수준에 따른 생육영향 분석

Since the salinity of irrigation water is a critical constraint to the production of certain vegetable crops, salinity was considered as one of the mostimportant factors of irrigation water. The purpose of this study were to monitor and assess the effects of saline irrigation water on strawberry and redradish growth in protected cultivation. One control and three treatments, which were differentiated according to the level of salinity in irrigated water,were employed for each vegetable to assess the effects of the irrigation with saline water. Monitoring has shown that using irrigation water with salinityabove a certain level causes excessive accumulation of sodium (Na+) in both strawberry and red radish. Increased Na+ content was analyzed to be ableto decrease the sugar content in strawberry. In addition, the salinity higher than the threshold level of irrigation water was found to reduce the growthand yield of strawberry and red radish. This study could contribute to suggest criteria for safe use of saline water in protected cultivation, althoughlong-term monitoring is needed to get more representative results.
