남부지방(南部地方)에서 황금(黃芩)의 맥후작(麥後作) 직파재배시 적정(直播栽培時 適定) 시비량(施肥量)을 구명(究明)하여 재배기술(栽培技術)을 개선(改善), 보완(補完)하고 수량(收量)을 증대(增大)시켜 안정생산(安定生産)에 기여(寄與)하고자 여천(麗川) 재래종(在來種)을 공시(供試)하여 실시(實施)한 시험결과(試驗結果)를 요약(要約)하면 다음과 같다. 1, 무비구(無肥區)(N-P2O5-K2O = 0 - 0 - 0kg/10a)의 개화기(開花期) 7월(月) 20일(日)에 비하여 모든 시비구(施肥區)가 7월(月) 21일(日)~23일(日)로 1~2일(日) 늦게 개화(開花)하였다. 2. 생육형질(生育形質)인 경장(莖長), 경태(莖太), 분지수(分枝數), 주근장(主根長), 주근경(主根徑) 생경엽중(生莖葉重), 건경엽동(乾莖葉重)은 무비구(無肥區)에 비하여 모든 시비구(施肥區) 양호(良好)하였으나 다비구(多肥區)(N-P2O5-K2O = 12-18-12kg/10a) 3. 수량형질(收量形質)인 건근중(乾根重)은 무비구(無肥區)보다 모든 시비구(施肥區)가 양호(良好)하였으나 그 중에서 중비구(中肥區)(N-P2O5-K2O = 9-13.5-9kg/10a)에서 10a당 건근중(乾根重)이 178kg으로 무비구(無肥區)의 126kg에 비(比)하여 41%가 증수(增收)되었고 표준시비구(標準施肥區)(N-P2O5-K2O = 6-9-6kg/10a)의 167kg에 비해서는 7%가 증수(增收)되었다.
This study was carried out to determine the effect of various fertilizer levels on the growth and yield of Scutellaria baicalensis Georg cultivated after the barley in the southern coastal areas of Korea under the non-mulching condition by direct sowing culture. The flowering date of medium dressing plot (N : P2O5 : K2O=9 : 13.5 : 9 kg/10a) and heavy dression plot (N : P2O5 : K2O=12 : 18 : 12kg/l0a) were July 23. The flowering date of the medium and the heavy dressing plot was delayed by 3days compared with that of non-fertilizing plot. The growth characteristics such as stem length, diameter of main stem, number of branch per plant, main root length, main root thickness and dry weight of stem leaves were more increased at medium dressing plot than that of other fertilizer levels. The root dry weight of in Scutellaria baicalensis Georg cultivated after barley was highest at the fertilizing plot of N, P2O5 : K2O = 9 : 13.5 : 9kg/10a. The dried-root yield was 178kg in medium dressing plot, 167kg in standard dressing pot, and 126kg in non-dressing plot. The dried-root yield of medium dressing plot was 7% and 41% higher than that of standard dressing pot and non-dressing control plot, respectively.
