Abstract

The purpose of this study was to examine the effects of black polyethylene film mulching and soil conditioners on the growth, yield, and flavonoids biosynthesis of mungbeans. The seedling stand rate, plant height, and pods per plant were 98%, 61 cm, and 15.1, respectively, when the mungbean grown black polyethylene film mulches. They were greater than these results when the without mulches was applied by 13%, 9 cm, and 1.8, respectively. Mungbean grown with black polyethylene film mulches ($243\;kg{\cdot}10a^{-1}$) exhibited 38% more seed yield than without mulches ($176\;kg{\cdot}10a^{-1}$). However, no significant difference in contents of vitexin and isovitexin of mungbeans between with black polyethylene film mulches and without mulches was observed. Among soil conditioners, standard fertilizer+oil cake and standard fertilizer+mineral powders increased number of pods. The standard fertilizer+oil cake showed the highest seed yield (119%) of mungbean when it mixed with standard fertilizers, and followed by mineral powders (115%). The mixed combinations of oil cake or mineral powders also seem to have affected the biosynthesis of vitexin and isovitexin, whose content in mungbeans was significantly more.

녹두 생육과 수량 및 flavonoids 생합성에 멀칭과 토양개량제의 효과를 구명하고자 본 연구를 수행하였다. 1. 녹두 흑색 polyethylene film 멀칭처리의 입모율은 98%, 경장은 61 cm, 개체장 협수는 15.1개로 무멀칭보다 각각 13%, 9 cm, 1.8개 많았다. 2. 녹두 멀칭처리의 수량은 $243\;kg{\cdot}10a^{-1}$로 무멀칭 $176\;kg{\cdot}10a^{-1}$보다 38% 많았으나, 종실의 vitexin과 isovitexin 생합성에는 효과가 없었다. 3. 토양개량제 중 표준시비+유박과 표준시비+광석분말 처리가 녹두 개체당 협수가 많고, 수량은 표준시비에 비해 표준시비+유박(119%), 표준시비+광석분말(115%) 순으로 많았다. 4. 표준시비에 유박과 광석분말 혼용은 녹두 vitexin과 isovitexin이 유의적으로 많아 이들 성분의 생합성에 영향을 미치는 것으로 판단된다.
