| 摘 要： | 采用小区试验研究了不同播种期对野香苏生长及产量的影响，以期为云南野香苏资源的开发利用提供参考。试验结果表明：野香苏种子萌发需5～8d，幼苗期生长较为缓慢，出苗后第10～15d长出第1对真叶。种子从萌发到成熟需133。196d，尽管播种期相差61d，但成熟期基本一致。营养生长期103～164d，繁殖期37～45d。播种期早，营养生长期较长，繁殖期花序和花的数量较多，穗数和产量较高；播种期晚，营养生长期相对较短，繁殖期花序和花的数量较少，穗数和产量较低。

| Abstract: | For providing reference on developing and making use of Elsholtzia rugulosa resources in Yunnan,the influences of different sowing dates on growth and yield of Elsholtzia rugulosa were investigated by plot test. The results showed that the seed germination of Elsholtzia rugulosa needed 5-8 days,the young seedlings grew slowly and the first pair of euphylla appeared in 10-15 days after seeding. The growth duration from seed germination to mature was 133-196 days. The mature period of different treatments was... |
