6년근 인삼재배에 적합한 우량묘삼을 생산하기 위하여 적합한 묘포양식과 토양개량제를 선발하고자 양직묘포 및 반 양직묘포 그리고 팽화왕겨와 펄라이트를 혼합 처리하여 시험한 결과를 요약하면 다음과 같다. 1. 묘포의 투수성은 양직묘포가 반 양직묘포보다, 팽화왕겨처리가 대조구보다 양호하였고, 공극률은 양직묘포가 반 양직묘포보다 2.23%, 팽화왕겨 처리구가 대조구보다 2% 높아 토양 물리성 개선효과 있었다. 2. 입모수는 묘포양식과 토양개량제 처리 시 차이는 없었으나, 엽면적은 양직묘포에서 반 양직묘포보다, 팽화왕겨와 펄라이트 처리구에서 대조구보다 뚜렷하게 감소하였다. 3. 근장, 근두직경 및 동체직경은 양직묘포에서 반 양직묘포 보다 길거나 굵었으나, 토양개량제 간에는 뚜렷한 차이가 없었고 건조률은 양직묘포에서 반 양직묘포보다 높았으나 토양개량제 간에는 차이가 없었으며 칸당 수확본수는 양직묘포에서 반 양직묘포에 비해 252본이 많았으나, 토양개량제 간에는 큰 차이가 없었다. 4. 식재가능묘삼비율은 양직묘포에서 반 양직묘포에 비하여 21.7%로 증가하였고, 양직묘포와 반 양직묘포에서 팽화왕겨에서 대조구보다 유의하게 높았다. 불용묘삼의 비율은 양직묘포에서 32.5%로 반 양직묘포의 59.4%에 비해 26.9%감소하였다.
This study was conducted to produce high quality ginseng seedlings by improvement of the physical properties of nursery soil. In order to select optimum nursery conditions, nursery types were treated with the yangiik nursery and semi-yangiik nursery. Soil conditioners were treated with two different materials of puffed rice husks and perlite. This experiments were tested at Gyunggido Agricultural Research and Extention Services, Hwaseng, from 2003 to 2004. Soil permeability was better at the plot of yangiik nursery than that of semi-yangjik nursery, and was better at plot of puffed rice husks than that of perlite. Soil porosity was improved 2.2% at plot of yangjiik nursery compare at that of semi-yangjik nursery, and was improved 2.0% at plot of puffed rice husks compared to control. There was no difference in the number of ginseng plants per kan among treatments. Root length was longer at plot of yangjik nursery than that of semi-yangjik nursery. More available ginseng plants per kan were obtained from the plot of yangjik nursery by more 252 seedlings than that of semi-yangjik nursery, but there was no significant difference between soil conditioners. The number of available seedlings per kan produced from yangjik nursery was 21.7% higher than those produced by semi-yangjik nursery. The number of available seedlings per kan produced from plot of puffed rice husks was 16.3% higher than that of control.
