      • 요소분해효소 억제물질의 작용과 응용에 관한 연구

        주영규 한국잔디학회 1992 한국잔디학회지 Vol.6 No.1

        Urea, the major N source of world agriculture involves a serious urea-N loss through NH$_3$volatilization. Approaches to decrease N loss include using urease inhibitors in view of the environmental protection and the increase of urea-N efficiency. The purpose of laboratory researches was toassess the potential value of urease inhibitors to increase urea-N efficiency in soil and Kentucky blue-grass(Poa Pratensis L.) turf. The activity of urease inhibitors Phenyiphosphorodiamjdate(ppD) and N-(n-butyl) thiophosphoric triamjde(NBPT) measured to break-down ammonia volatilization. The soil and turf used in this project were from the fairway in one of the Korean gof course. The researches were carried out for two weeks to measure the urease activities on urea hydrolysis under four temperatures (10~ 40$^{\circ}C$) and for one week on turfgrass using forced-draft system. Results indicated that Urea-N involves considerable loss through gaseous NH$_3$ by urease activities in plant-soil systems. Urease inhibitors PPD and NBPT have potential value for increasing N use efficiency by reduing NH$_3$ volatilization. NBPT deserves futher evaluation as fertilizer amendment than PPD use of urea in turf industries.

      • 축분 유기질비료의 고형화에 의한 비효 연장

        주영규,정영상,이상국,김은규,Joo Young-Kyoo,Jung Yeong-Sang,Lee Sang-Kook,Kim Eun-Kyu 한국잔디학회 2004 한국잔디학회지 Vol.18 No.2

        Solid typed organic fertilizer from cattle manure may Increase plant root growth with the residual effect on soil fertility if it was applied directly into root system. It may also increase labour efficiency by simplifying the work process of manure application to soil. This research was carried out from May to October 1999 to study the fertility prolongation effects of bar typed organic fertilizer from poultry manure by analysing plant growth model compare with those of the chemical fertilizer or powder typed manure. The results showed that the bar typed organic fertilizer increased growth rates of shoot and root system with extending the effect of its fertility by slow releasing on pepper plant. Especially, solidifying organic manure into the bar type made possible the application of cattle manure under plastic mulching. And it also has benefits on simplifying the application process of the fertilization and effect on an extending soil fertility. 축분 유기질 성분을 고형화된 막대 형태고 조형하여 작물 뿌리 주위에 관입하게 되면 작업과정의 단순화와 비효의 유실을 줄이고 비효 지속 기간을 연장 시키어 작물의 근계 발육에 매우 효과적일 것으로 사료된다. 따라서 본 연구는 화학 비료, 분말 형태의 유기질 비료와 막대형 유기질 비료의 비효를 비교하고 작육의 생장 형태를 분석하여 축분의 막대화에 따른 유기질 비료의 효과지속성을 측정하는데 목적을 두고 실험을 실시하였다. 그 결과, 분말형태의 축분 사용보다는 고형화된 막대형태의 유기질 축분이 비효의 유출을 줄이고 작물 지상부와 근계발달을 촉진시켜 유기질 비료 특유의 완효성 비효의 지속에 효과가 있다는 것이 증명되었다. 특히 멀칭 후에는 분말 형태의 축분 시비가 불가능하나, 이를 막대 형태로 고형화하여 작물 근계 주위에 관입하게 되면 작업과정의 단순화해지며, 수확 후에도 토양 비옥도를 지속적으로 유지 시킬 수 있을 것으로 판단되었다.

      • 이식 시기와 초종에 따른 잔디뿌리의 활착력

        주영규,김덕환,이성호,이정호 한국잔디학회 2003 한국잔디학회지 Vol.17 No.2

        본 연구는 이식 후 경기를 수용할 수 있는 잔디의 생육기간과 잔디뿌리의 활착 요구기간을 측정함으로써 2002년 월드컵 잔디그라운드 조성 공사에서 발생될 문제를 예측하고 이를 해결하는데 필요한 자료를 얻기 위하여 1998년부터 2000년까지 2년에 걸쳐 월드컵 경기장과 동일한 지반에서 포장실험을 실시하였다. 한지형잔디와 한국잔디 모두 묘포장의 뗏장에서 경기장 그라운드로의 이식시기는 잔디의 활착력과 근계 발달에 직접적인 영향을 미쳤으며 초종에 따라 그 영향은 달리 나타났다. 한국잔디로 그라운드를 조성하려면 한지형잔디와 달리 충분한 양생기간을 확보한 적기에 뗏장을 식재하는 것이 좋았다. 또한 동계 간 보온 등의 관리가 수반되면 지하부의 발육과 근계 활착이 동계에도 지속되어 활착력이 조기에 증가하는 것을 알 수 있었다. A series of studies was conducted during 2 years to investigate the effect of transplanting time and turfgrass species on turf establishment rate of sod for 2002 World Cup Soccer ground construction. The required period of rooting and turf growth for acceptable soccer playing quality on transplanted sod from nursery was tested to collect data for the project authorities of hosting cities and construction companies who were involved in World Cup stadium project. Transplanting time significantly affects on rooting-potential of sod on cool season grass and zoysiagrass, but those effects differently showed by turfgrass species. The enough nursing period for the ground established by Zousiagrass should be secured with proper transplanting time. And the thermal insulation on the turf canopy with other maintenance during Winter should improve the early rooting on zoysiagrass. The sod contained Kentucky bluegrass (85%+15% perennial ryegrass, seed wt. basis) showed relatively slow at the early growth and rooting-potential of root, but the potential resulted higher than that of perennial ryegrass turf (85%+15% Kentucky) under longer nursing period. Kentucky bluegrass has one of the most strong resistance against environmental stresses, but intensive maintenance practise should be required when the turf transplanted during summer season. Higher mixture rate of perennial ryegrass sod has a rapid root growth compare with other turfgrass species. The rate provided a benefit to an early establishment of turf ground followed by a proper maintenance practise. For the completion of World Cup soccer ground construction for 2002, the most suitable time for sod transplanting in 2001 was March to May or mid Sept. to early Oct. by delayed architect construction schedule.

      • Pseudomonas spp.의 Rhizoctonia solani 및 Pythium spp. 병원균에 대한 길항작용

        주영규,한정훈 한국잔디학회 1994 한국잔디학회지 Vol.8 No.1

        Attempts were made to investigate the antagonistic activity of soil borne microorganisms Pseudomonas spp. and Trichoderma spp. against to the pathogens of turf diseases Rhizoctionia solani spp. and Pythiom spp. in vitro by a dual culture bioassay. Inhibition zone between the edge of the my-celium and the margin of each antagonistic bacteria, Pocudontonas, on potato dextrose agar was measured 3 days after incubation at 28˚C. Psudomonas spp. showed relatively high inhibition of mycelium growth of R. solani AG-i and Pythium spp. which cause brown patch and pythium blight, respectively. Antagonistic fungi Trichodenma spp. also showed effective inhibition against mycelium growth of both pathogens, more proper methods of measuring the inhibition effects were required because of fast growth of Trichodenna hypae. Brown patch and pythium blight both, re-quire most higher rate of fungicide use to control in golf curses in Korea. Application of antagon-istic microorganisms are useful as biological resources an approach to sole environmental contamination.

      • 야생초 가공에 의한 종자분사공법 재료화 기술

        주영규,김성균 한국잔디학회 1997 한국잔디학회지 Vol.11 No.3

        This study was performed to develope the method of wildgrass to process as hydroseeding material which is a most popular revegetation method for Slope areas through the control of soil eroison and stability by seeding grasses. The wildgrass material for the processing were harvested at Suwon, Kyungki-do and Wonju, Kangwon-do in 1994. The investigations were established in laboratory for pot and field experiment with seven treatments by harvesting date and place in 1995. Results indicated that wildgrass harvested field in open space or road side was able to be used as hydroseeding material by proper processing. It was possible to substitute wildgrass seed to conrrnercial turfgrass seed, and plant tissue to mulching fiber by drying and crushing process. Germination of wildgrass seed was relatively slower than control (20g /$m^2$ turfgrass seed) in early stage of 20 days, but surface revegetation rate was higher in 50 days at wildgrass plot than control applied by normal hydroseeding method. Mixture of 5g /$m^2$ of cool season turfgrass seed to wildgrass material increased the rate of early stage of germination and surface revegetation. The application of wildgrass as hydroseeding material showed more naturalistic scenery than rutine hydroseeding with imported cool season turfgrass seed. Key words: Rydroseeding, Turfgrass, Wildgrass, Revegetation.

      • 한국잔디류(Zoysia Grass)의 육종현황

        주영규,김두환,이재필,모숙연 한국잔디학회 1997 한국잔디학회지 Vol.11 No.1

        Although zoysia grass (Zoysia spp.) has a lot of excellent chracteristics as warm-season grass, it have been limited in use due to slow establishment, low seed production, poor shade tolerance and other factors. Breeding trials have been continued from 1900's, much attentions have been paid especially in U.S.A., Korea and Japan recently. In U.S.A., more than 24 varieties had been evaluated at National Turfgrass Evaluation Program(NTEP) from 1991 to 1995 and some were regsistered as commercial. After the 6th International Turfgrass Research Conference at Japan in 1989, Japan Turfgrass In-corporation (JTI) sponsored by private companies and government carried out breeding programs for pest, salt, and shade tolerant and herbicide resistant varieties. JTI also has been trying to im-prove vigor and breed evergreen zoysia Korean breeders collected germplasms since 1960's. After USDA breeders came to Korean penesula in 1982, Korean breeders joined with USDA zoysia breeding project for several years. Many interspecific hybrids and natural selected varieties were breeded that period both in U.S.A and Korea. Breeding objectives were to extend green color period, improve leaf quality and density, and better leaf color at dormant stage. Since 1990's, zoysia grass breeding trials are getting more diverse in many points such as random amplified polymorphic DNA (RAPD) assay for ecotype identification. The objectives of this study are to evaluate germplasms in Korea, and also review the present status and future prospect in zoysia grass breeding in the world.
