강원 북부지역 큰꽃삽주의 논 토양 재배시 재배방법에 따른 생육양상

다국어 초록 (Multilingual Abstract)

Background : Atractylodes macrocephala is a perennial herbaceous plant belonging to the family Asteraceae and should be cultivated in field soils with good water dripping due to plant characteristics. However, cultivating farmers mainly have recently been cultivated in paddy soil due to their regional characteristics, which causes the decrease in yield due to poor drainage. Therefore, this study was carried out to investigate the cultivation in high ridge and subsoil breaking effect for stable paddy soils cultivation technology of A. macrocephala.
Methods and Results : Soil was paddy soils in the fall of 2017, and the pH (1 : 5) was 6.61 ± 0.15 as a result of chemical and physical properties. EC was 0.49 ± 0.05 dS/m, and organic matter content was 28.69 ± 69 g/㎏ and effective phosphoric acid was 306 ± 17.8 ㎎/㎏. As a result of the soil layering survey, the surface layer was 0 - 26 ㎝ deep as paddy soil mounded with sandy loam in the past. In the surface layer, there was a light layer after 17 ㎝ depth, and volume density was 1.71 ± 1.3 g/㎤. The porosity of the plow pan was 33.41 ± 2.34%. The cultivation methods were cultivation in high ridge (30 ㎝ or more) and level row (10 ㎝ or less) at 2 levels and 3 repetitions. In subsoil breaking, the depth of the plow pan was increased from 17.1 ± 0.5 ㎝ before treatment to 31.1 ± 3.6 ㎝ after treatment and the hardness was 24.8 ± 1.5 ㎜. In the case of rotary plowing, the depth of the plow pan was 17.1 ± 1.9 ㎝ before treatment and 26 ± 2.4 ㎝ after treatment and the hardness was 25.8 ± 2.9 ㎜. The medium growth characteristics of A. macrocephala per treatment showed the tendency of increase in plant length, culm length, number of nodes, number of leaves, and fresh weight in level row cultivation after subsoil breaking. Root growth of cultivation in high ridge after subsoil breaking tended to be good with rhizome weight of 11.6 g per hill. The survival percentages were 98.8 - 100% and the bolting rate was 93.4 - 96.2%
Conclusion : In cultivation in high ridge after subsoil breaking in the paddy field of Gangwon area, the decrease of yield of A. macrocephala due to drainage was expected to be alleviated, but final conclusion should be drawn after analyzing soil temperature and soil moisture data.
