人參 根腐病에 關한 硏究<第二報> : 人參圃 土壤中의 菌類에 垂直分布 및 菌種 分類에 대하여 = Study on the Root Rot of Ginseng

국문 초록 (Abstract)

本 實驗은 人蔘圃 土壤中 根腐病이 發生한 곳과 發病않은 無病地 및 人蔘을 耕作않았든 土壤을 選定하여 捷息하는 菌類의 土壤別 垂直分包와 菌類를 分類하였고 土壤의 物理化學的 性質을 調査하여 다음과 같은 結果를 報告하고자 한다.
1. 土壤의 酸度는 各個 土壤이 均一하고 모두 酸性을 나타냈다.
2. 有機物의 含量은 5%의 有意差가 있어 無耕作地＞羅病地＞無病地와 같은 關係가 있다.
3. 無機物의 含量으로 CA과 Ksms 差異가 없고 P_2O_5와 Mg는 無病地와 蕪耕作地보다 5%의 有意差로 더 많이 함유하였다.
4. Cs와 Fs値는 無病地가 羅病地와 無耕作地 보다 5% 有意差로 差異가 있다.
5. Silt는 無病地가 他地區보다 더 적은 5%의 有意差가 있었다.
6. 水分含量은 統計的으로 差異이나 無病地에 比較的 적게 含有되엇다.
7. 菌類의 垂直分布는 一般的으로 各土壤 供히 表土層에 多數分布하는 경향이 있고 深層에 가까울수록 적어지는 경향이 있다. 統計的으로 無病地는 地區 보다 적으며 5%의 有意差가 있었다.
8. 羅病地 土壤은 10屬 21種의 菌腫이 分布하고 Aspergillus와 Penicillium屬이 多數分布하고 Rhizopus와 Nigrospora屬의 分布가 적었다.
9. 無病地는 12屬 17種으로 Asp. Pen. 및 Spicaria屬 등의 分布가 多數이고 Mucor Marrsonia 및 Rhizoctonia屬 등이 적게 분포하였다.
10. 無耕作地는 10屬 10種이 分布하고 Asp. Peb.屬이 多數分布하고 Hyalopus屬와 Thamnidium屬이 적게 分布하였다.

다국어 초록 (Multilingual Abstract)

This study was carried out March, 1973. the aim of this study was to know the relationship between soil conditions and population of vertical fungi distribution and species founded in the soil of uncultivated plot of ginseng diseased and healthy plot of ginseng in Kang wha-Gun, Korea. Acidity of each soil was uniformly acid. Organic matter content was 5 per cent significance in each soil; uncultivated plot was significance to diseased and healthy plot, and diseased plot was significance to healthy plot. As inorganic matter, Ca and K contents were uniform in all plot, but P_2O_5 and Mg were 5 per cent significance; healthy plot contain more quantity than the other two plot. Cs and Fs value were 5 per cent significance; healthy plot contatin more quantity than the other two plot. Silt was also 5 per cent significance; uncultivated and diseased plot contain more quantity than healthy plot.
Moisture content was statistically uniform in all plot, but it was less in healthy plot. Numbers of fungi were largely distributed on the surface soil, and decrease with depth. As the numbers of fungi, healthy plot was significance to other two plot which cantain larger numbers.
As to the species, diseased plot had 10 genera and 21 species, healthy plot had 12 genera and 17 species, and uncultivated plot had 10 genera 10 species. There was dominantly populated Aspergillus, Penicillum and Spicaria, but Rhizopus, Nigrospora, Marrsonia, Rhizoctonia, Hyalopus and Thamnidum group genera were recessively distributed.
