  • 본 시험은 파종시기를 한달 간격으로 두었을 때 숙기가 다른 사일리지용 옥수수의 수량과 사료가치를 높이기 위한 적정 수확시기를 알기 위하여 수행하였다. 전식물체, 경엽, 암이삭 및 알곡의 건물률은 상대숙도가 다른 품종간에 차이가 뚜렷하였다(P<0.05). 암이삭 비율은 조생종인 DK501과 P3514 품종이 높았으며, 파종기간에는 조기파종이 만기파종보다 높았고 수확시기는 늦어짐에 따라 암이삭의 비율이 증가하였다. 건물수량 및 TDN 수량은 조중생종인 P3514 및 P3352가 가장 높았으며 조생종인 DK501이 가장 낮았다.(중략)

  • This study was conducted to find a way to improve quality by observing changes in quality and microbial communities according to whether corn silage was treated with additives and the storage period, and to utilize them as basic research results. The experimental design was performed by 2×4 factor desigh, and the untreated (CON), and the additive inoculated (ADD) silage were stored and fermented for 30 (TH), 60 (ST), 90 (NT), and 120 (OHT) days, with each condition repeated 3 times. There was no change in the nutrient content of corn silage according to additive treatment and storage period (p>0.05). However, the change in DM and the increase in the relative proportions of lactic acid content and Lactobacillales according to the storage period (p<0.05) indicate that continuous fermentation progressed until OHT days of fermentation. Enterobacterales (33.0%), Flavobacteriales (14.4%), Sphingobacteriales (12.7%), Burkholderiales (9.28%) and Pseudomonadales (6.18%) dominated before fermentation of corn silage, but after fermentation, the diversity of microorganisms decreased sharply due to the dominance of Lactobacillales (69.4%) and Bacillales (11.5%), Eubacteriales (7.59%). Therefore, silage maintained good fermentation quality with or without microbial additives throughout all fermentation periods, but considering the persistence of fermentation even in long-term storage and the aerobic stability, it would be advantageous to use microbial additives.

Effect of Herbicide Combination on Agronomic Characteristics, Dry matter Yield, Nutritive Value and Weed Control of Silage Corn in Alpine Area (고랭지에서 제초제 조합에 의한 사일리지용 옥수수의 생육특성, 건물수량, 사료가치 및 잡초방제에 미치는 영향)

  • This study was conducted to select the optimum herbicide combination on agronomic characteristics, dry matter yield, nutritive values and weed control of the silage corn at Daekwanryong branch(altitude 800m a.s.1.) of National Livestock Research Institute from 2001 to 2002. The treatments consisted of control, metolachlor, thiobencarb+linuron, pendimethalin, pendimethalin+linuron, propisochlor, nicosulfuron, propisochlor+nicosulfuron, and non treatment. The plant height and ear height of corn were no significant different among herbicide combination. However, the highest dry matter(DM) and ear rate of silage corn were observed with nicosulfuron treatment; 31.4% and 52.7%, respectively. Also, Dry matter yield of silage corn was the highest of 16,503kg/ha with propisochlor+nicosulfuron(P<0.05). The control of annual weeds was the greatest of 96.4% in the plots of propisochlor+nicosulfuron application. These results indicate that propisochlor+nicosulfuron treatment would be the optimum combination for dry matter yield, weed control and nutritive value of silage corn in alpine area.
