To study the effects of different altitudes and sowing dates on direct sowing Angelica sinensis biomass, yield and quality, and to provide a theoretical basis for Angelica sinensis direct sowing cultivation techniques.
Two factors trials were used to research the influence of altitude and sowing dates on yield and quality of direct sowing Angelica sinensis. The altitudes were located at 2500, 2000 and 1500 m, and the sowing dates were set up at autumn August 29, and Spring April 3 and April 24. The experiments were designed with split plot.
Under the same altitude, roots and aboveground biomass of direct sowing Angelica sinensis were higher when sowing earlier. In the same sowing date, the root and aboveground biomass was the maximum at 2 000 m altitude, followed by elevation of 1 500 m. At 2 500 m altitude, Angelica sinensis root and aboveground biomass was the minimum. Sowing at 2 000 m altitude at August 29 direct sowing Angelica sinensis showed the highest biomass and yield, reaching 13 840.95 kg/hm2, significantly higher than the other treatments. Compared with transplanting Angelica sinensis in this region, the production of direct sowing Angelica sinensis was also 15. 3% higher. Angelica sinensis medicinal grade was significantly higher than the rest of the process. Angelica sinensis extract, volatile oil and ferulic acid content had reached the standard of Chinese Pharmacopoeia.
Angelica sinensis sowed in late August at 2000 m altitude has the best yield and quality on root length, root diameter, plant height, leaf number, dry and fresh matter accumulation, followed by 1500 m altitude, and 2500 m worst. Therefore, altitude range of Angelica sinensis direct sowing cultivation area can be reduced to 1500-2000 m.
Angelica sinensis sowed in late August, at 2000 m altitude, the indicators like root length,root diameter,plant height,leaf number,and dry and fresh matter accumulation showed the best, followed by 1500 m altitude, 2500 m worst. Therefore, altitude range of Angelica sinensis direct sowing cultivation area can be reduced to 1500~2000 m.
研究不同海拔和播种期对直播当归生物量、产量及品质的影响，为当归直播栽培技术提供理论依据。
采用二因素试验研究海拔和播种期对直播当归产量和品质的影响。海拔设置为2500、2000和1500米，播种期设置为秋季8月29日，春季4月3日和4月24日。试验采用裂区设计。
在相同海拔条件下，直播当归的根和地上生物量在较早播种时较高。在相同播种期，海拔2000米时根和地上生物量最大，其次是海拔1500米。在海拔2500米时，当归的根和地上生物量最小。8月29日在海拔2000米处直播当归生物量和产量最高，达13840.95千克/公顷，显著高于其他处理。与该地区移栽当归相比，直播当归产量也高出15.3%。当归药用等级显著高于其他处理。当归提取物、挥发油和阿魏酸含量均达到《中国药典》标准。
8月下旬在海拔2000米处播种的当归在根长、根直径、株高、叶片数、干鲜物质积累等产量和品质指标方面表现最佳，其次是海拔1500米，海拔2500米最差。因此，当归直播栽培适宜海拔范围可缩小至1500 - 2000米。
