摘要：

为了给云木香GAP种植技术提供科学依据，研究了不同播期与种植密度对云木香产量及主要农艺性状的影响。采用随机区组排列，播期设置3/15（月/日）（A1）、3/25（A2）、4/5（A3）、4/15（A4）、4/25（A5）五个水平；种植密度设置穴行距30×10 cm（B1）、30×20 cm（B2）、30×30 cm（B3）、30×40 cm（B4）、30×50 cm（B5）五个水平。结果表明：播期、种植密度对云木香的产量均有显著影响，在播期为A3、A4、密度为B2、B3时产量较高，农艺性状较理想。25处理组合中，A3B2、A3B3、A4B2、A4B3较为理想，4月中上旬、30×20 cm和30×30 cm为分别当地云木香适宜的播期和种植密度。

Abstract:

The Effects of different seeding periods and plant densities on Yield and Main Agronomic Characters of Saussurea lappa in Yunnan were studied in order to provide scientific basis for GAP cultivation techniques. Designing five seeding periods of 3/15 (A1,month/day), 3/25 (A2, month/day), 4/5 (A3, month/day), 4/15 (A4 ,month/day), 4/25 (A5), Designing five planting densities of 30×10 cm(B1), 30×20 cm(B2), 30×30 cm(B3), 30×40 cm(B4), 30×50 cm(B5) by random arrangement. The results showed that the effects of seeding periods and plant densities on yield and main agronomic characters of Saussurea lappa in Yunnan were obvious; the yield of A3, A4 and B2, B3 were higher ,the main agronomic characters of A3, A4 and B2、B3 were good. A3B2, A3B3, A4B2 and A4B3 were the preferable treatment combinations. The suitable seeding periods of Saussurea lappa in YunNan were in early and middle of April. The suitable plant densities of Saussurea lappa in YunNan were 30×20 cm (B2), 30×30 cm (B3).
