영문 초록

Stable production of green manure crop is one of the critical factor for successful implementation of environmental-friendly agriculture in South Korea. Most green manure crops including hairy vetch cultivated in South Korea must be passed cold winter season. This study was conducted to establishment of cultivation zones on green manure crops under paddy field in South Korea using on minimum temperature and drainage class. In order to build the spatial distribution map, hairy vetch, triticale, barley, rye, and clover as green manure crop were selected and mean of daily minimum temperature and drainage class in paddy field were considered as limiting factor for stable growth of green manure crop. And cultivation zone on green manure crops was divided into two categories; ‘Availability area’ and ‘Safety area’. Low limit temperature on green manure crops in this study was the following. Temperature on ‘Availability area’ was –10℃, –8℃, –6℃, and –20℃ for hairy vetch (including triticale), barley, clover, and rye respectively. And temperature on ‘Safety area’ was lower –2℃ compared to that of ‘Availability area’ exception rye which was the same degree. Rye was expected to safely cultivated the almost whole paddy field (99.71%) of South Korea. ‘Safety area’ among the whole paddy field for hairy vetch, barley, and clover were 86.58, 53.06, and 15.76% respectively. The spatial distribution map of green manure crops reestablished in this study could be used the policy and agricultural management for environmental-friendly agriculture using green manure crops in South Korea.
