Seed production of italian ryegrass has a problem of lodging during ripening and a decrease in quality due to difficulty in drying seeds during harvest. Therefore, in order to produce high-quality Italian ryegrass in paddy fields, it was carried out to reduce the density and solve the lodging problem through transplanting. In this experiment, Lolium multiflorum cv. Kowinearly was transplanted in autumn from a paddy field in Sindong-ri, Gwansan-eup, Jangheung-gun, Jeollanam-do. var. Kowinearly was made into a bed at 90 g/box and stacked in boxes. It was transplanted on October 27th after 2 days of germination at 30℃ and 15 days of seedling and greening. When transplanting, they were transplanted at intervals of 30×14cm. The existing cultivation method, drill seedling, was sowed at a level of 50 kg/ha, and both transplanting and drilling were carried out at a nitrogen fertilization rate of 45 kg/ha. The number of ears during transplant cultivation was 1,016/m² and the drilling tended to be higher at 2,278/m², but this was probably due to the difference in seeding amount. The seed number of an ear tended to be 56% higher in transplantation, which had a significant impact on yield. The seed yield was 2,096 ka/ha in transplantation, which was 21% higher than that of drilling. When looking at the relationship with weed occurrence, there were areas where all the weeds, such as amul foxtail, occurred due to the low density. Even in the same transplanting area, the seed yield was about 1,000kg/ha less in the area where the weeds were abundant. It seems that weed management is important in paddy cultivation. Therefore, it seems necessary to develop an exclusive herbicide for Italian ryegrass cultivation.

농가현장에서 이끼재배에 활용할 수 있는 기존의 연구자료가 거의 없는 실정에서 분화식물로서 관상가치가 높은 나무이끼의 재배기술을 개발하고자 투명용기 재배시 토양 습도, 적정 공기노출 정도구명, 적정 용토 구명, 지피용 이끼선발 등 상품화에 관한 연구를 수행하였다. 나무이끼의 투명용기 재배시 용기내에 수분을 적습(수분 60~80%)으로 관리하는 것이 좋으며 용토는 피트모스:펄라이트(7:3)의 상토에서 좋았고 공기노출 정도에 있어서는 완전밀폐와 10% 노출에서 생육이 좋았다. 용기의 공기유통 정도를 나타내는 천공형태는 상부천공 2구에서 생육이 좋고 내부에 습기가 맺히지 않았다. 투명 용기내의 적정 용토는 수태, 피트모스, 피트모스+펄라이트 구에서 생육이 좋았으나 수태는 가격이 비싸 경제성이 떨어지므로 피트모스나 피트모스+펄라이트 상토가 유리한 것으로 나타났다. 나무이끼와 어울릴 수 있는 지피용 이끼로는 솔이끼, 편평털깃털이끼, 깃털이끼, 털깃털이끼, 아기초롱이끼, 은이끼, 가는털깃털이끼, 표주박이끼, 흰털이끼, 꼬마이끼 등 10종 모두 초장이 0.7~2.7 cm로 나무이끼보다 1 cm이상 작아 지피용으로 적당한 것으로 나타났다.

본 연구는 국화 재배온실에서 사용되고 있으면서 수작업 시 많은 노동시간이 요구되는 국화 유인네트를 대상으로 작업의 소요시간을 대폭 절감시켜 재배 작기를 증가시킴은 물론 국화재배용 유인네트의 베드를 기존 및 신축 국화재배 온실에 보급할 목적으로 네트의 베드를 설계한 후, 베드 및 기존 온실의 구조적 안전성을 검토하였다. 총 15종류의 부재에 대한 단면의 특성과 역학적 성질을 검토하고 각각의 부재에 대한 응력비를 검토한 결과, 이들 파이프 중 ${\phi}38.1{\times}1.7t$와 ${\phi}38.1{\times}2.0t$의 경우, 응력비는 초과하지 않았지만 처짐의 제한 값인 10mm를 초과하였으므로 응력비와 처짐의 제한 값을 모두 만족하는 최적 파이프는 ${\phi}48.1{\times}1.5t$인 것으로 나타났다. 유인네트의 베드를 중방에 설치할 경우, 베드 하중, 풍하중 및 설하중 때문에 중방은 트러스로 설계되어야 안전한 것으로 나타났다. 중방을 트러스로 시공할 경우에도 풍하중 및 설하중이 작용하면, 베드의 유무에 관계없이 거창지역의 국화재배 온실의 경우, 기둥과 방풍벽에 발생되는 응력은 허용응력을 초과하기 때문에 적절한 보강이 필요한 것으로 나타났다.

A research was made through a experimental cultivation during a period of 7 years (1956~1962) to determine the yearly yield, the total gross yield over 7 year's period and the maximum availability of stock timbers used as the germination bed of cortinellus edodes (Berk) Ido et Imai. The results are summarized as follows : (1) Research and plot scheme: Two experimental plots were established-plot "A" in the experimental forest of this college; plot "B" in the campus woods, 400 timber beds were furnished in each. The kinds of timbers used are : Quercus Serrata Thumb 140. Quercus acutissima Carr. 140, Quercus crispula BI 120. The environmental condition in plot "A" was better then that in plot "B" and the former showed greater yield than the latter. (2) yield : In plot "A" the total yield was 58.875kg and some of the timbers was still continuing germ in this seven after closing of the plot. In plot "B" the total yield was 56.90kg and after the sixth year no more germination was observed. In conclusion, plot "A" showed greater yield and longer germination than plot "B". (3) Germination efficacy and the kinds of timber: The best result was abserved on Quercus serrata, thumb Quercur acutissima Carr, stood next and then came Quercus crispula BI. Betula platyphylla was tried, but the result was worst. (4) Availability limits of timber beds: Quercus serrata Thumb with diameter 12~15cm had the longest availability more than (6~7 years) and Quercus acutissima Carr with diameter 12~15cm showed 6~7 year's availability. The shortest availability was found in Quercus crispula with diameter 6~9cm. Any kinds of timber with diameter 6~9cm had only 4~5 years of availability (5) In the table showing the yearly germination quantity, the figure of December and Jaunary of the 4th and 5th year shows the yield obtained in the semi-cellar paper house. This tells that there is good promise of winter cultivation of cortinellus edodes (Berk) Ido et Imai on matured timber beds.
