摘要：【目的】比较研究当归熟地育苗试验及大田栽培试验,分析当归产区熟地育苗的适宜播期和播种量。【方法】采用二因素随机区组设计,设置不同播期和播种量当归熟地育苗试验,测定当归种苗形态指标及产量,移栽后统计成活率、早期抽薹率、植株特征,采挖后测定药材产量及阿魏酸含量。【结果】不同播期和播种量育成当归种苗在大小、产量及移栽后成活率、早期抽薹率、形态指标、药材产量及阿魏酸含量方面均有差异。第1、2播期所产当归种苗单根重在0.45~0.63 g,符合生产要求。第2播期5 kg/667m^(2)的播种量下药材产量比同播期7 kg/667m^(2)的高76.26%,且早期抽薹率为0。【结论】熟地育苗应在6月下旬进行,播种量控制在5~6 kg/667m^(2),苗龄控制在110 d,可获得符合生产要求的当归种苗。
【Objective】To clarify the appropriate sowing date and sowing amount of ripe seedling raising in Angelica sinensis producing areas by carrying out its seedling raising test in cultivated fields and comparative test of drug preparation stage.【Methods】The experiment adopted the two-factor split zero group design by setting up different sowing dates and sowing amounts to cultivate seedlings in the cultivated fields of A.sinensis,and measured the morphological indices and calculated the survival rate,early-bolting rate,plant characteristics,yield and ferulic acid content after transplanting.【Results】There were differences in the size,yield and survival rate after transplanting,early-bolting rate,morphological indexes,crude drug yield and ferulic acid content of A.sinensis seedlings.The root weight of A.sinensis seedlings in the first and second sowing date ranged from 0.45-0.63 g,which met the production requirements.In the second sowing date,the yield was 76.26%higher at 5 kg/667m^(2) than that at 7 kg/667m^(2) in the same sowing date and the early-bolting rate was 0.【Conclusion】In the production area of A.sinensis,seedlings should be raised in cultivated fields in late June,the sowing amount controlled in the range of 5-6 kg/667m^(2),and the seedling age controlled in 110 days,which might meet the production demand for the A.sinensis seedlings.
