Abstract
|
|
|
Background: Roots of Astragalus membranaceus (Fisch.) Bunge have medicinal uses. This study was conducted to select promising succeeding crops by planting 10 different kinds of medicinal crops such as balloon flower on continuously cropped and firstly cropped land, for comparing and investigating the yields of each crop.
Methods and Results: For the yield evaluation of 10 kinds of medicinal crops in continuously cropped land and firstly cropped land, test field located in Songhak-myeon, Jecheon-si, Chungcheongbuk-do was selected. In order to maintain the cultivated area for medicinal crops while avoiding the injury by continuous cropping, 10 kinds of candidate crops those can be harvested in that same year with a high domestic cultivation area were planted for selecting promising succeeding crops of Astragalus membranaceus (Fisch.) Bunge. The yield was evaluated at the optimal harvest time of the crops. The yield of Peucedanum japonicum Thunberg and Platycodon grandiflorum A. De Candolle in the continuously cropped land was significantly higher than in the firstly cropped land.
Conclusions: These results may help enhance the understanding of the selection of promising medicinal crops in continuously cropped land and to establish countermeasures for injury by continuous cropping research.
