Sclerotia of Grifola umbellata were cultivated by two methods such as burying and root inoculation methods. The sclerotia of G. umbellata produced by the burying method were $6.0{\sim}6.8{\times}3.4{\sim}4.6{\times}1.8{\sim}1.9cm$(Width$\times$Length$\times$Thickness) in size and $17.3{\sim}19.6g$ in weight, respectively. Their increase rate was $1.10{\times}1.12$ times. On the other hand, the sclerotia cultivated by the root inoculation method were $18.3{\sim}31.5{\times}12.5{\sim}26.4{\times}3.1{\sim}3.7cm(W{\times}L{\times}T)$ in size and $219.1{\sim}576.6g$ in weight, respectively. Their growth increment was $11.18{\sim}39.77$ times. The rhizomorphs of Armillaria mellea were developed with a high density under fallen leaves layer covering cultivation site, and distributed mainly between soil surface and soil depth of about 10 cm as well as colonized prominently on the inoculated wood logs. Fungal interaction between G. umbellata and A. mellea were observed mainly in the stage of white sclerotium of G. umbellata. The sclerotia of G. umbellata which were developed newly and harvested in the root inoculation method were twined with root hairs of host tree and rhizomorphs of A. mellea. The sclerotia of G. umbellata decomposing root hairs of host tree were confirmed through SEM examination. Physiochemical characteristics of soil in all cultivation sites had no significant differences. Soil pH were in the range of pH $3.98{\sim}4.40$. Organic matters were the range of $17.97{\sim}23.86%$ and moisture contents of soil were $12.00{\sim}18.20%$. Soil temperatures showed $12.9{\sim}13.8^{\circ}C$ in November and $22.0{\sim}23.9^{\circ}C$ in August, respectively. In conclusion, the root inoculation method seems to be a practical method for cultivating sclerotia of G. umbellata due to its many advantages such as simplicity of inoculation process, shortening of cultivation periods and facility of harvest.

To maintain the self-sufficiency of food production , it is required to improved the productivity and increase the effective utilization of land in the double cropping areas using improved cultivation technology. The following reasons encourage this cours of action because the overlapping rice harvest and barely seeding seasons complete for labour, the lower price of barley makes it financially less attractive to grow and these two facts together are responsible for a decrease in barley being planted in certain more seasonably marginal double cropping areas. Fro these reasons, it is desirable to carry out tests to improve the current cultivation techniques . In this interest , the following studies were carried out in the experimental field located at Banweol-myeon, Whasung-jkun, Gyeonggi-do from October 1977 to July 1978 in order to establish the mechanical method of barley cultivation using the power tiller. The summarized results are as follows. 1. The work performance in the seeding operation using the rotary barley seeder was 68 minutes per 10 ares which compares favourably with 408 min/10a using the conventional method. This is only one sixth of the time required by th conventional method. The operating costs using the rotary barley seeder was 1, 463 won per 10 areas as against 3, 486 Won per 10 ares for the conventional method, showing a saving of about 50% in comparison with the conventional method. 2. In the manure spreading operation, the work performance was 25 min/10a for the manure spreading machine , compared to 1089 min/10a for the manual operations. This is about one fourth of the time required by the conventional method, The operating costs were 810 Won/10a for the machine and 857 Won/10a for the manual labour. This cost shows little advantage by the machine over the manual labor costs. The conventional method of manure spreading will continue pending decision which will develope and improve the machine.3. Work performance in the rolling operation using the barley rolIer was 30 min/lOa which compares favourably with 135 min/10a using conventional method. This was one fourth of the time required by the conventional method. The operating costs were 514 Won/103. for the machine and 1, 003 Won/lOa for manual labour. In the weed control operation, the work performance and operating costs were 45min/lOa, 1, 399won/10a for the herbcide application using the power sprayer, 1, 149min/10a 8, 541won/lOa for the conventional method respectively. This is 26 times higher efficiency in comparison to the conventional method. 4. In the harvesting operation using the reaper binder and tiller attachment, the work performance was 60min/lOa and represents a cost of 2, 039won/10a. The con\ulcornerventional method took 640min/10a at a cost of 4, 757won/lOa. The reaper binder showns a saving of one tenth over the conventional method. The automatic thresher is already recommended for the current situations, and is now being used. 5. From a comparison of the results of the above trials, the serial cultivation system using the attachment for the power tiller such as the rotary barley seeder is now to be recommended for the current barley cultivation system. It is also recommend from these results that the mechanized technology now available must be used to improve and maintain the increase in barley production. It is seen th1t this is the only course now avaihble to solve the peak seasonal requirements of labour needed for l11rvesting and seeding between rice and barley cultivation.

Estimation of current and future loading from watershed is necessary for the sound management of water quality of an estuary lake. Pollution sources of point and non-point source pollution were surveyed and Identified for the Koheung watershed. Unit factor method was used to estimate potential pollutant load from the watershed of current conditions. Flow rate and water qualify of base flow and storm-runoff were monitored in the main streams of the watershed. Estimation of runoff pollutant loading from the watershed into the lake in current conditions was conducted by GWLF model after calibration using observed data. Prospective pollutant loading from the reclaimed paddy fields under cultivation conditions was estimated using the modified CREAMS model. As a result, changes of pollutant loading into estuary lake according to non-cultivation and cultivation conditions of reclaimed tidal land were estimated.

왕송이버섯의 인공재배법을 개발하기 위하여 농업과학기술원에서 보존중인 MKACC50852 등 4개 균주를 사용하였으며 우선 이들의 RAPD 분석을 통한 유전적 다형성을 분석하여 유사도를 알아보았다. 일본에서 수집한 MKACC50852균주와 인천에서 채집한 자생균주인 MKACC53368이 높은 유연관계를 보였으며, 제주도에서 채집한 MKACC50853은 태국에서 수집한 MKACC53359와 높은 유연관계를 보였다. 왕송이버섯의 인공재배 방법을 개발하기 위해 봉지재배 및 상자매몰 재배를 비교 실험한 결과, 봉지재배가 상자재배보다 초발이소요일수가 빨랐으며 발이정도에서는 큰 차이는 보이지 않았다. 균주별 자실체 발생에서 MKACC50852 및 MKACC53368는 버섯이 발생되었으며 그 외의 균주는 버섯이 발생하지 않았다. 특히, MKACC50852가 자실체의 품질 및 발이율이 가장 높았으며 복토 후 균상생장도 양호하였다. 왕송이버섯의 재배사내 습도별 자실체 생장율은 발이 후 습도를 80%이상 유지 시 자실체 생장율이 좋았으며, 복토 후 균사생장 완료전 약 70%정도 균사 생장시 하온 처리에 의한 발이유기가 효과적이라고 생각되며 발이유기 및 자실체 생장시 주야간 온도편차 유지가 가능하고 환기가 용이한 재배사가 적절하다고 판단된다. 왕송이버섯의 간편한 재배 체계를 확립하고자 폐면 및 톱밥배지를 사용하여 상자재배와 봉지재배시 미강, 밀기울 등 첨가제를 각각 3, 5, 7%씩 처리하여 자실체발생 및 수량을 조사한 결과, 첨가제 중 미강 처리구보다는 밀기울 처리구에서 균사생장이 양호하였으며 배양기간과 발이기간도 단축되었으나, 수량은 폐면 단용구에 비해 낮았다. 균주별로는 MKACC50852 균주가 폐면단용구에서 발이 및 수량(455g/봉지)이 가장 양호하였으며 MKACC53359는 비록 수량은 낮은 편이었으나 처리별로 고른 발이율을 보였다. 결론적으로, 왕송이버섯 자실체 발생을 위해서는 첨가제의 종류보다는 재배환경요인이 더 큰 영향을 준다고 생각된다.
