Abstract
The purpose of this project was to develop good agricultural practice through studying the effects on the yield, quality and active ingredients in different cultivated areas and cultivation management of Angelica acutiloba. The characters of A. acutiloba were measured and compared from harvests cultivated in five different areas within Hualien County from 2007 to 2009. In comparison of the average root weight of A. acutiloba, the highest value was obtained from roots cultivated in Shoufeng area. Those roots with highest active ingredient content of ferulic acid and Z-liguistilide were the harvest cultivated in Yuli area. It is also found October is the most appropriate cultivated period for A. acutiloba. Among the growth stages, the full bloom stage had the highest root yield, and this is the most suited period for harvest. As for comparison on the agronomic traits of different day lengths on growth, two hundred and five days had the highest value in plant height, root weight and root width. Those of two hundred and five growth days had the highest ferulic acid content in A. acutiloba. Harvest of one hundred and sixty growth days had the highest Z-liguistilide content in A. acutiloba. In organic fertilizer trial, those with application rate at 8,000 kg ha-1 had the highest root yield. The planting density 100 × 60 cm had the highest root yield. There was no increase effect with cut flowers in the root yield of the flowering in A. acutiloba. The mulching treatment with non-woven fabric and weed control mat material had the highest root yield than other mulching material. The transplanting cultivation had higher root yield than direct seeding method, yet in the root diameter, the direct seeding was larger than transplanting. The good agricultural practice of A. acutiloba will be introduced to farmers in the future in order to produce the high yield, stable quality, and high active ingredients contents of the A. acutiloba.
