초록
Recent years, there is increasing demand for seedlings of Daphniphyllum macropodum. However,the bare-root nursery of the species has been reported to be challenging due to meteorological disasterscaused by climate change. The study aims to investigate the appropriate levels of shade and fertilization ofcontainer-grown D. macropodum, which has shade tolerance in seedling stage. The shading treatment wasregulated with the shading level of full sun, and 35%, 55%, 75% of full sun. The fertilizing level was madeby regulating Multifeed 19 (N:P:K =19:19:19, v/v) with 1000mg·L-1, 2000mg·L-1, 3000mg·L-1, togetherwith the control. The height was indicated to be the highest in 3000mg·L-1 under 55% of shading. Theroot collar diameter was surveyed to be the highest in 1000mg·L-1 and 3000mg·L-1 of full sun. A case ofthe whole dry mass production was surveyed to be the highest in 3000mg·L-1 under 55% of shading and2000mg·L-1 under 35% of shading. Moreover, the study is to explore the possibility of production andsound growth of D. macropodum seedlings by container nursery; consequently, the result is expected toprovide the production method of the seedlings of D. macropodum that is to overcome meteorologicaldisasters from bare-root nursery.
Abstract
Recent years, there is increasing demand for seedlings of Daphniphyllum macropodum. However,the bare-root nursery of the species has been reported to be challenging due to meteorological disasterscaused by climate change. The study aims to investigate the appropriate levels of shade and fertilization ofcontainer-grown D. macropodum, which has shade tolerance in seedling stage. The shading treatment wasregulated with the shading level of full sun, and 35%, 55%, 75% of full sun. The fertilizing level was madeby regulating Multifeed 19 (N:P:K =19:19:19, v/v) with 1000mg·L-1, 2000mg·L-1, 3000mg·L-1, togetherwith the control. The height was indicated to be the highest in 3000mg·L-1 under 55% of shading. Theroot collar diameter was surveyed to be the highest in 1000mg·L-1 and 3000mg·L-1 of full sun. A case ofthe whole dry mass production was surveyed to be the highest in 3000mg·L-1 under 55% of shading and2000mg·L-1 under 35% of shading. Moreover, the study is to explore the possibility of production andsound growth of D. macropodum seedlings by container nursery; consequently, the result is expected toprovide the production method of the seedlings of D. macropodum that is to overcome meteorologicaldisasters from bare-root nursery.
