腐植含量이 지렁이 生育에 미치는 영향을 調査하기 위하여 각각 다른 腐植水準의 土壤에서 지렁이의 飼育試驗, 그리고 지렁이의 土壤中 生活生態 및 作物에 對한 農業撤布가 作物(早生大長가지) 生育에 미치는 영향에 관한 試驗, 그러고 지렁이 個體數가 가지生育에 미치는 영향에 관한 試驗, 또한 3種의 土壤病菌의 菌系生長에 대한 지렁이의 糞 및 磨碎濾液의 沮止效果를 檢計한 試驗 等에서 다음과 같은 結果를 얻었다. 1. 生存率은 낙시지렁이에서는 g, d, f處理에서 줄지렁이는 g, d處理에서 왕지렁이는 g, d處理에서 높은 傾向을 보였다. 2. 繁殖率은 낙시지렁이, 줄지렁이는 d處理에서 왕지렁이는 f, g處理에서 좋은 結果를 보였다. 3. 繁殖率과 Total-N은 낙시지렁이, 줄지렁이, 왕지렁이에서 正相關이 인정되었다. 4. 生存率과 腐植含量에서는 낙시지렁이, 줄지렁이에서 正相關이 인정되었다. 5. 繁殖率과 Total-N 및 腐植含量에서는 낙시지렁이, 줄지렁이에서만 正相關 인정되었다. 6. 農藥處理는 가지 및 지렁이의 生育과 生存數에서 有意性이 認定되지 아니했다. 7. 草丈. 無處理區에서 73.67cm, NAC-Wp區가 73cm로 크고 Nitrofen-Wp區은 59.67cm로 작았다. 8. 收量은 CAT-Wp區가 27個, Nitrafen-Wp區, 無處理區가 各 26個로 많고 Heptachlor-D區는 17個로 적었다. 9. 果重은 除草劑인 CAT-Wp區, Nitrofen-Wp區가 119,9g, 118,73g으로 무겁고 Reldan-Ec區은 93.70g으로 가벼웠다. 10. 果長은 無處理區, NAC-Wp區가 17.98cm, 15.84cm였고 Reldan-Ec區는 14.27cm로 작았다. 11. 지렁이 生存數는 Heptachlor-D區가 약 21마리로 높고 CAT-Wp區가 17마리로 제일 낮았다. 12. 收獲期別 收量은 8月 29日 57個로 많은 8月 17日 11個로 적었다. 13. 收獲期別 果長은 8月 17日은 20.99cm 길었고 9月 8日은 13.56cm였다. 14. 收獲期別 果重은 8月 4日 159.24g으로 무거운 9月 8日 65.11g였다. 15. Reldan-Ec, DEP-Ec는 Nitrofen-Wp부다 TLM의 相對效果가 29.64倍 20.41倍의 傾向을 보였다. 16. 지렁이의 무게가 395±25mg일 때 Redan-Ec, 0.0075% DEP-Ec0.0108%, Heptachlor-D 0.0114%, CAT-Wp0.0699%가 TLM濃度였다. 17. 農藥 DEP-Ec, Re1dan-Ec Heptachlor-D NAC-WpCAT-Wp Nitrofen-Wp의 LD90의 濃度는 0.0416%, 0.0305%, 0.0368%, 0.2416%, 0.3097%, 0.8277%였다. 18. 지렁이 個體數는 가지葉數에서 有意的인 增加를 보였다. 19. 지렁이 個體數는 가지의 果實數量增收에는 별다른 영향을 주지 않았다. 20. 지렁이 個體數는 가지栽培에서 안산과 加里質 肥料의 適量 混合施用이 必要하다고 認定되었다. 21. 供試된 3個菌株 모두 菌系生長을 抑制하는 지렁이糞의 沮止效果는 나타나지 않았다. 22. 菌系生長을 抑制하는 지렁이의 磨碎濾液의 沮止效果는 供試된 菌株中 Sclerot ium rol-fsii에서는 明白히 나타났으나 Rhizoctonia solani에서는 諸定할 수 없었으며, Fusarium solani는 오히려 菌사生長이 促進되었다. In order to study the effect of compost application on earthworm cultivation, a factorial experiment was carried out at each level of compost application, and also to check the effect of ecology of earthworms in soil as an effect of spraying crops is a field with agricultural chemicals, and also to check the effect of earthworm number to eggplant growth, to investigate the inhibitory effects of earthworm fecal wastes and earthworm extracts on the mycelial growth of soil pathogen fungi; and the results were as follows. 1. Relatively high increasing trend of the reproductive rate of earth worm was appeared at plots, d g f in Allolobophora japonica of g plot in Eisenia foetida, and plots f g in Pheretima communissima, respectively. 2. Reasonablely good effect of earthworm survival rate was shown at the plot d in Allo1ophora japonica, Eisenia foetida and plot f g in Pheretima communissima. 3. statistically positive correlation was convinced at plots between reproductive rate and total-N in all experimented earthworm species. 4. Statistical significance were revealed at plots between survival rate and compost in Allolobophora japonica and Eisenia foetida. 5. Statistical significance was also revealed at plots between reproductive rate and total-N or compost application in Allolobophora japonica and Esenia foetida. 6. Spraying agricultural chemicals was not presumed to be significant as a result of the survived number of earhworms and eggplant growing. 7. The height of the herbs and the weeds in non-treated area with chemicals were 73.67cm, in the NAC-Wp, as tall as 73cm, and in the Nitrofen-Wp area, was as short as 59.67cm. 8. Yields of eggplant treated with CAP-Wp were 27pcs. and both in the Nitrofen-Wp area and non-treated area were as much as 26 pcs., respectively; and in the Heptachlor-D area was 17 pcs. 9. The weight of the eggplant in the CAT-Wp area and the Nitrofen-Wp area treated with herbicide were as heavy as 119.92 gr. and 118.73 gr. respectively. And 63.73 gr. in the Reldan-Ec area. 10. The height of the eggplant with blank test area and the NAC-Wp area was 17.98cm and 15.38cm respectively. And Reldan-Ec area was 14.27cm. 11. The survived number of earthworms at Heptachlor-D area were 21 approximately. the lowest survived number was shown in the EAT-Wp area, 17. 12. Eggplant yield classified by harvesting season were 57 pcs. on August 9th; and as little as 11 pcs. on August 17th. 13. The height of eggplants classified by harvest season was 20.29cm on August 17th; and 13.56cm on September 8th. 14. The weight of eggplant classified by harvest season was 159.24 gr. on August 4th; and 65.11 gr. on september 8th. 15. The relative affectiveness of T(LM) in Reldan-Ec and CAP-EC was shown 29.64 times and 20.41 times as compared with the Nitrofen-Wp. 16. As the weight of earthworms reached 395-25mgs, the TLM concentration in Reldan-Ec was 0.007%;and in the CAT-Wp was 0.0699% respectively. 17. The concentration of L(D) percentage in the agricultural chemicals; DEP-Ec, Reldan-Ec, Heptachlor-D,%, 0.0305%, 0.0368%, 0.2416%, 0.3097% and 0.8277%. respectively. 18. Statistically high signiftcance on the number of earthworm was revealed in terms of eggplant leaves. 19. No significant effect was convinced in terms of increasing eggplant fruits. 20. Adequate application of phosphorus and potash fertilizer to the soil in which the earth worm grown was recommended for eggplant culitivation. 21. There was no visible inhibitory effect of earth worm fecal wastes on the mycelial growth of soil pathogenic fungi examined. 22. The obvious inhibitory effect of earth worm extracts on the mycelial growth was found in Sclerotium rolfsii but was recognized in Rhizoctonia solani and oppositely the stimulating effect of earthworm extracts on the mycelial growth was noticed in Fusarium solani.
