중북부 지방에서 호맥의 청예와 종실수량 연구
Utilization and Yield of Forage and Grain on Winter Rye in Northern and Central Areas of Korea
초록
본 실험은 팔당호밀을 사용하여, 우리나라 중북부 지방에서 월동전 청초 이용후 종실을 생산할 수 있는지를 검토코저, 춘천, 수원, 화성 및 청주에서 2개년 동안 실시하였다. 파종기는 각 지역 모두 4파종시기로서, 청초예취는 월동직전 1회 예취하여 실시하였으며 그 결과를 요약하면 다음과 같다. 1. 월동전 예취시 초장,
In order for Paldanghomil (winter rye) to be investigated if its grain yield is able to be produced after clipping just before winter season for forage utilization this experiment was carried out under the four sowing dates of four locations in Korea (Chunchon, Suwon, Hwasung and Chungju). In rye clipping plot earlier sowing showed taller plant height, more number of tillers/㎡ and higher forage yield before winter season, indicating the highest forage yield (1803 kg/10a) in Chunchon by sowing of September II. Forage yield of rye before winter season was mainly influenced by plant height and number of tillers/㎡, showing more effect of plant height. Rye plants were more or less affected on winter damages, late heading and short culm by clipping before winter season. Analysis of variance indicated that only number of spikes/㎡ among grain yield components showed the high significance according to the clipping method, and that there showed little variation for other yield components due to the sowing date and clipping method. There showed more grain yield in non-clipping rather than that of clipping plot, indicating the difference of 46kg/10a. This was resulted from short culm and severe winter damages caused by clipping before winter season. Of the grain yield components, number of spikes/㎡ was greatly influenced for grain yield by analysis of stepwise regression. Therefore, grain yield of rye was able to produce after forage utilization before winter season due to the appropriate crop and soil managements, by resulting from the little variation in grain yield between clipping or non-clipping plots and from the higher grain yield by the early sowing.
