Abstract

Chinese cabbage cultivation has been typically practiced in alpine sloped farmland in Gangwon province, and caused severe soil erosion by soil disturbance like tillage. Cultivation of wild edible greens such as Aster scaber Thunb. and Ligularia fischeri Turcz. could be one of alternative ways to reduce soil erosion, because their residues become stubble mulch after harvest, and there is no need for tillage every year. Therefore, the objective of this research was to estimate the effect of nitrogen application rates for the maximum production of Aster scaber Thunb. and Ligularia fischeri Turcz. in the early cultivation stages. Total N contents of Aster scaber Thunb. and Ligularia fischeri Turcz. increased with the increment of fertilizer application rates. Maximum growth of Aster scaber Thunb. and Ligularia fischeri Turcz. was observed with the highest rates of fertilizer. We obtained the relationship between Aster scaber Thunb. and N application rate, as y = $-0.296x^2$ + 73.82x + 5246 (R = 0.998). There was no significant difference for Aster scaber Thunb production between N application rates for 120 and 160 kg/ha. Also, the relationship between Ligularia fischeri Turcz. and N application rate was y = $-0.135x^2$ + 32.86x + 1529 ($R^2$ = 0.965) in the first year trial after transplanting.

환경조건이 불량한 고랭지 경사지 밭에서 정식 초기 산채 (곰취, 참취)류의 생육 및 수량과양분함량의 관계를 검토하고자 시험을 실시하였다. 시험 후 토양 화학성 변화는 참취, 곰취 시험포 모두 비료 시용량이 증가함에 따라 다소 높아졌고, 토양유기물 함량은 요소 처리보다 부산물퇴비 시용구가 높은 것으로 나타났다. 수확기 참취 및 곰취의 총 질소 함량은 질소시비량이 증가 할수록 높아졌으나 부산물퇴비 처리구에서는 경향성이 없는 것으로 나타났다. 참취 및 곰취 모두 질소시비량이 많을수록 생육이 양호한 것으로 나타났으며, 참취 생육의 경우 질소 120 kg/ha 처리구와 160 kg/ha 처리구에서 가장 높은 생육을 나타났다. 참취의 수량도 질소 처리 수준이 증가할수록 수량은 증가하여 질소 120 kg/ha 처리구와 160 kg/ha 처리구에서 높게 나타났으며, 160kg/ha 처리구에서는 다소 감소하였으나 통계적으로는 유의성이 없는 것으로 나타났다.
